Abstract:
A measurement device is disclosed, embodiments of which are adapted to withstand, detect, and record detection of heat cycle events, including autoclave cycles. Embodiments of the measurement device comprise a sensor for measuring a characteristic of a medium and a heat cycle detection unit. Embodiments of the heat cycle detection unit comprise a temperature or atmospheric pressure responsive element, a detection module, data interface, and data memory. In one disclosed embodiment, the temperature or pressure responsive element is configured to respond to a characteristic of a heat cycle event while the heat cycle detection unit is off. In another disclosed embodiment, the detection module is configured to automatically power off the heat cycle detection unit in response to detecting an autoclave cycle. Methods of using the devices are also disclosed.
Abstract:
A counter includes: a count processing circuit including a nonvolatile register; a regulator receiving voltage from a direct current power supply, generating power supply voltage based on the received voltage for the count processing circuit, and supplying the power supply voltage to the count processing circuit; and a delay circuit receiving the power supply voltage and supplying a count signal to the count processing circuit after the power supply voltage is supplied to the count processing circuit. After having received the power supply voltage from the regulator, the count processing circuit updates a count value in response to the count signal and holds the updated count value in the nonvolatile register in a non-volatile manner.
Abstract:
An electrical process and device are described wherein interruptions in the passage of yarn from a series of supply bobbins, used in succession, to a wind-up bobbin are detected by a yarn breakage surveying device that transmits an impulse for each interruption. Some of these interruptions are due to supply bobbin changing and others to yarn breakages. Only the interruptions due to breakages are transmitted to a counter by way of a gate that receives the said impulses as well as periodic signals from a timing device. The timing device is actuated for spaced periods initiated by signals from a differentiating circuit for each change from "no yarn" to "yarn present" indicated by the surveying device, the latter being connected to the differentiating circuit as well as directly to the timing circuit. Each timing circuit period is limited to a total which is less than the average period required for each supply bobbin to unwind, but for each yarn breakage a gap appears in an associated one of the periods, the gate transmitting an impulse to the counter only when such a gap arises.
Abstract:
A conveyor loading and counting system is described for deriving a count and controlling operation of a conveyor for transporting articles between a loading and unloading area. The system includes loading and unloading area count registering means coupled to and controlling loading and unloading area counting and read-out means, respectively. The loading area count registering means includes a loading area count registering trigger mounted on a conveyor mechanism for moving completed articles from the loading area to an unloading area with the trigger means being actuated by a completed article passing over the conveyor mechanism for registering one unit count for each completed article transported by the conveyor mechanism out of the loading area into the unloading area. The conveyor mechanism includes a power driven portion that normally in its inactive condition engages a completed article subsequent to the completed article being loaded upon the conveyor mechanism and wherein the count registering trigger of the loading area counter, in addition to registering a unit count for each completed article loaded upon the conveyor mechanism, also actuates the power driven portion of the conveyor to cause the conveyor to move the article off the trigger a sufficient distance to assure return of the trigger to its normally inactive position (thereby recording one count) while simultaneously loading the power driven portion of the conveyor with one completed article. The conveyor mechanism preferably includes a plurality of different located count assuring stops for accommodating different types of articles produced by the manufacturing facility and being loaded on the conveyor. The system also further includes a plurality of different characteristic article counters at both the loading areas for deriving a count of each different type of article completed in the manufacturing facility and a type of article selector for selectively activating a desired one of the differently located count assuring stops and different characteristic article counters. The system also further includes at least one over-delivery sensing and inactivating control means for sensing a build up of unloaded articles being delivered to the discharge-unloading end of the conveyor mechanism above a predetermined number, and for inactivating the power driven portion of the conveyor mechanism in response thereto. Further, manually operable control means also are provided for inactivating the power driven portion of the conveyor at the option of an operator-unloader working at the discharge-unloading end of the conveyor.
Abstract:
An intermittent drive mechanism for an encoding device is driven by a continuously rotating drive source. First and second Geneva drive discs are each rotated through a sequence of rotated rapid incremental displacements to a plurality of positions each of which are utilized for providing coded information. The first Geneva drive disc is rotated by a drive means which is moved to a high energy level condition by the drive source and permitted to rapidly discharge. A second drive means is connected to the first disc and is moved to a high energy level condition by rotation of the first disc and permitted to discharge to rapidly drive the second disc.
