Abstract:
A color coded safety belt or harness to be worn by a person to protect the person from a fall and the method of making and using the belt or harness. The belt or harness is formed of first fibers of a predetermined first color, e.g., optical yellow, and also includes at least one color coded indicator fiber woven therein to indicate the year of the manufacture of the belt or harness. The indicator fiber is of a second color which contrasts with the color of the belt or harness fibers to enable the user of the belt or harness to determine if the belt or harness had been produced more than a predetermined number of years before so that a decision can be made by the user of whether or not to discard the belt or harness due to its age. The second color of the indicator fiber is a predetermined different color than the first color, and is changed in successive years, without repeating the second color.
Abstract:
Microcode is loaded into, for example, a processor or I/O module within a computer system without manually halting and restarting the computer system. In other words, microcode can be loaded into the computer system dynamically while data processing continues from the processor or I/O module states just prior to the microcode load with no major interruption to the user. A microcode image is loaded into a processor which is already executing one or more tasks. A request to load microcode into the processor is received. The processor is signalled to suspend task execution. After the microcode image is transferred into the processor, the processor is signalled to resume task execution.
Abstract:
A system and method of use for attaching a safety rope to an elevated portion of a tower, e.g., an electric power transmission tower, so that the rope extends along the tower's leg from the elevated portion to a lower portion, e.g., the ground, to enable a worker may be secured to the rope by a safety device, e.g., a rope grab, to protect the worker from a fall. The system comprises an air rifle for shooting a projectile having a light weight flexible filament secured to it over the elevated portion of the tower, the safety rope, and plural rope-retaining gates. Once the projectile has been shot over the tower to carry the filament over the elevated portion the safety rope is connected to the filament and pulled over the elevated portion of the tower. The safety rope is then secured in place extending vertically between the elevated portion and the ground. Plural gates are mounted on the tower's leg at spaced locations therealong to hold the safety rope close to the tower leg so that it cannot flap or blow around in the wind. A worker can then attach a safety device on the rope and climb up the tower, while being protected from a fall therefrom.
Abstract:
An ice-gripping sandal for securement to other primary footwear. The sandal comprises a sole, a toe strapping assembly and a heel strapping assembly. The sole has plural groups of cleats projecting therefrom. Some of the cleats extend at an acute angle to the longitudinal axis of the sole and include portions having ice-gripping screws. Grooves are provided between the cleats in the forefoot and toe portions of the sole. The width and depth of those grooves increase from the medial side of the sole to the lateral side of the sole to facilitate the release of material which may tend to adhere therein when the wearer walks. The toe strapping assembly includes plural flexible straps which produce an adjustable size toe box for receipt of the toe of the primary footwear. The straps of both of the strapping assemblies include VELCRO.RTM. fastening strips.
Abstract:
A connector device for releasable securement to a post of scaffolding on which a worker wearing a safety restraint member, e.g., safety belt and associated lanyard, will be disposed. The post terminates at a free upper end. The connector device basically comprises a hollow cup-shaped member formed of any suitable flexible material, e.g., a fabric of nylon or polyester, having a top portion and a downwardly extending peripheral skirt portion. The hollow interior is arranged to receive the top free end of the scaffold post therein. A reinforcing patch is disposed at the top of the hollow interior to abut the top free end of the scaffold post when it is located within the hollow interior of the connecting device. A ring, e.g., of metal, is pivotally secured to the outside of the downwardly depending skirt and is arranged to have the safety device, e.g., the lanyard, releasably secured thereto when the cup-shaped connector device is mounted on the scaffold post.
Abstract:
An ice-gripping sandal for securement to the sole of a boot or other primary footwear. The sandal comprises a sole and plural attachment straps for mounting the sandal on the boot. The sandal's sole has a bottom surface having plural ice-gripping teeth. The attachment straps are secured to the sole and comprise a short front strap and a long front strap and a pair of short rear straps. The long front strap is arranged to be extended through a loop in the short front strap and about the upper of the boot through loops in the rear straps so that its free end is connected to a buckle mounted on the short front strap at the toe of the boot, thereby forming "figure 8" strap pattern. A pair of cooperating VELCRO.RTM. fastening strips are secured onto the long strap to hold the long strap in the buckle.
Abstract:
A rope grab for protecting a worker at an elevated position from a fall. The rope grab is disposed on a vertically extending safety line and is connected to the worker by a lanyard. The rope grab includes housing having a pivotable actuator mounted thereon. The actuator includes an serrated extension for engaging the safety line. A rupturable capsule containing an indicating liquid is located in the housing. The actuator is connected to the lanyard to secure the worker to the rope grab and is pivotable upon a downward pull thereon to move the serrated extension from a first position to a second position. When the serrated extension is in the first position it engages the safety line slightly to permit the rope grab to be slid therealong. When it is in the second position it tightly engages the safety line to preclude the device from being slid along said safety line, and causes the automatic rupturing of the chamber, whereupon the indicator liquid flows onto a portion of the rope grab and a portion of the safety line. The actuator is also arranged to be moved to a third intermediate position wherein the rope grab is precluded from sliding along the safety line but the capsule is not ruptured.
Abstract:
A lanyard for connection to safety device, e.g., a belt or harness, worn by a worker and for connection to an anchor point. The lanyard is arranged to be used in a method to prevent the worker from falling. The lanyard comprising a flexible member, e.g., nylon or polyester webbing, having first, second, and third, elongated sections, each of the sections having a first end and a second end. The second ends of all of the sections are connected, e.g., sewn, to one another. Each of the first ends of the lanyard includes a respective connector, e.g., a clasp, mounted thereon. In accordance with the method of use the connector of the first section is releasably secured to the safety device, while the connectors of the second and third sections are releasably secured to the anchor point. A shock absorber may be included in the first section of the lanyard.

Each rapelling strap includes a passageway through which a waist belt extends to releasably secure it to the harness. The waist belt includes a positionable tool case thereon. A positioning pad may be releasably secured to the waist belt.
Abstract:
A plurality of test cells in a cuvette is optically measured while the cuvette is manually moved through a sensing light beam. The cuvette is exposed in an open channel exposed to ambient light and is manually moved through the sensing light beam at an arbitrary rate. Abrupt changes in the optical density sensed by the beam are used to trigger the storage of the light beam intensity as an accepted measurement. The abrupt change is determined by comparing the currently read optical density of the cell against a predetermined moving average of previously read optical densities. A modulated sensing beam is received by a photodetector and converted from an analog to a digital signal by a fast A-to-D converter. The output of the A-to-D converter is coupled to a central processing unit which also includes as its input a bar code reader reading from a optically coded strip such instructions which are necessary to describe the number of cells, the test to be determined and other processing or reporting information. Abrupt changes in optical density caused by the passage of the edge of a cuvette cell triggers the generation of an accepted measurement from which an enzyme immunoassay test is performed.
