Abstract:
A harness or belt to be worn by a person connected to some elevated anchor point, e.g., a rope grab on a safety line, to prevent the person from a fall. The device comprises at least one web or strap of a fabric which is subject to a shock load when the device has been used to arrest the fall of the person and plural shock load indicating strands or fibers located on the web or strap. The web or strap is a generally flat member having an exterior surface and is formed of plural interlaced strands of a first stretchable, yet strong material, e.g., nylon or polyester. The shock load indicating strands are of a contrasting color to the strands forming the strap or web and are visible from the exterior surface of the web. The shock load indicating strands are of a lesser stretchability than the strands of the web or strap. Accordingly, upon the shock loading of the harness or belt the shock load indicating strands rupture and fray out of the exterior surface of the web, whereupon the frayed ends are readily visible. This appearance indicates that the device has been used to arrest a fall and should be discarded or refurbished.

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. A heel retainer in the form of a projection is located at the rear of the sole of the sandal for frictionally engaging the vertically extending portion of the heel of the primary footwear to aid in holding the sandal in place. The heel retainer includes a top surface which is arranged to be stepped on to facilitate the removal of the sandal from the footwear.
Abstract:
A safety system for connection to at least one fixed, elongated, structural component, e.g., an I-beam, of a static structure, e.g., a building being erected, to protect a worker located on the structure from falling thereoff. The system comprising first and second releasably securable mounting assemblies frictionally secured at respective spaced locations on the structural component, a rope or cable connected between the mounting assemblies, and a sliding anchor mounted on the rope. The sliding anchor comprising a tubular member mounted on the rope means for sliding therealong to a desired position whereupon it can be actuated to releasably secured it against further sliding. The worker wears a supporting belt, harness or other device, which is connected, via a lanyard and an associated shock absorber, to the sliding anchor, to thereby prevent he/she from falling more than a predetermined distance away from said sliding anchor.
Abstract:
A portable support system for use on the roof of a building to support an object and/or person therefrom. The system is arranged to be readily rolled to a desired position adjacent the edge of the roof and includes two wheeled frame assemblies and a collapsible/extendable boom assembly. The boom assembly comprising pivotable sections arranged to be extended from a compact orientation to an extended orientation and vice versa. The frame assemblies are arranged for connection to respective portions of the boom assembly. When the boom assembly is in the compact orientation the frame assemblies are closely connected together via plural connecting members to form a compact cart. The frame assemblies each include a pair of spaced wheels which can pivot in any direction to enable the cart to be readily wheeled to a position at the edge of the roof. The frame assemblies are then disconnected from the connecting members, and the boom sections extended so that the frame assemblies are spaced further apart for stability. A portion of the boom assembly extends over the edge of the roof to support a person/object therefrom. When the system is in position supporting the person/object the wheels are locked into an orientation so that they may only roll in directions transverse to the axis of the extended boom so that the system may roll along the edge of the roof, if desired.
Abstract:
A safety apparatus to be worn by a person located at an elevated position for releasable securement to a holding device, e.g., a rope grab, etc., to protect the person from falling. The apparatus also enables the person to move about relatively unencumbered when supported by it, while also enabling the person to repel down a safety line located adjacent the holding device.

The first belt is releasably secured about the waist of the person and includes at least one connector, e.g., a D-ring, for releasable securement to the holding device. The second belt comprises an elongated web-like member having a pair of ends, each of which is fixedly secured to the first belt. The second belt is disposed in a stowed position interposed betweeen the first belt and the lower portion of the back of the person but is arranged to be pulled out and down from the first belt to form a seat for the buttocks of the person. Each of the extendable straps is fixedly secured to the second belt has a free end arranged to be readily connected to a lowering device mounted on the safety line to enable the person to repel down the line once he or she has disconnected the first belt from the holding device.
Abstract:
A flow control device for controlling the flow rate of liquid through a flexible tube which comprises a body having sides and a slot to receive the flexible tube passing through the body. The slot commences at one of the sides of the body and the length of the slot is sufficient to receive most of the tube. The slot has sides spaced apart a predetermined distance sufficient to bear against the sides of the tube when in position in the slot to deform the tube inwardly and evenly along those sides a sufficient degree to provide an even, predetermined reduced flow rate through the tube. Because the tube is constricted in a routine manner by the slot of the device, a predictable reduced flow rate can be achieved for outlet tubes of a similar construction and diameter, making it possible to achieve a predetermined, proper flow rate through that tube. This device provides surprising reliability when used on a tube in conjunction with a liquid dispensing outlet controller, for simultaneous flow of milk from a bag of whole milk and a bag of reconstituted powdered milk, to achieve proper relative flow rates through the tubes from the two bags of milk.
