摘要:
An improvement for a steering differential for a tracked vehicle comprising a liquid cooled, hydraulically operated disc brake, two of which are normally used upon the differential to brake and steer the vehicle. A number of stationary discs are keyed internally to a brake body, with a number of rotating discs dispersed therebetween and splined to a braking axle of the differential, the rotating and stationary discs being hydraulically compressed together to apply braking torque to the braking axle. Oil or other suitable liquid is pumped through the brake body and radially through grooves on the faces of the discs to prevent excessive heating of the discs and the brake.

The present invention relates to a process for producing lignocellulose composite materials by combining lignocellulose particles with a binder composition, followed by molding or compressing the combined lignocellulose particles and binder composition. Suitable binder compositions comprise a polymethylene poly(phenylisocyanate) component and a liquid hydrophobic diluent that is characterized by a flash point of at least 250° F.

A loading head for loading food articles into packaging includes a transfer conveyor in operable communication with a source of articles to be loaded. The transfer conveyor communicates the articles from an upper receiving position to a lower loading position. A first drive drives the transfer conveyor at a variable speed. A second drive oscillates the transfer conveyor between a first position and a second position. A controller is in operable association with the first and second drives for varying the driving speed of the transfer conveyor as a function of the position of the transfer conveyor. An article holder is disposed at the loading position for receipt of a transferred article.
摘要:
Electrically conductive, pressure sensitive adhesive composite formulations comprising adhesive polymers, electrically conductive quaternary ammonium polymers, electrically conductive water soluble and water swellable polymeric fillers for imparting cohesiveness to said composite, and additionally, chemical agents that retard oxidative or microbial degradation of the composite. The composite formulations yield a flexible and extensible material that is suitable as an adhesive for biological electrodes, particularly transcutaneous electrical nerve stimulation electrodes.
摘要:
An imprinting system with a typeface for transferring ink from an inked ribbon onto a substrate including a first resilient member having an exposed surface located opposite the typeface, and the inked ribbon and substrate disposeable between the typeface and the first resilient member. The first resilient member is mounted on a first rigid member which is supported by a second resilient member supported by a second rigid member. The first resilient member has a durometer hardness greater than a hardness of the second resilient member, wherein the second resilient member is compressible between the first rigid member and the second rigid member to absorb shock from the typeface impacting against the first resilient member during imprinting.
摘要:
A method and apparatus for a hot stamp imprinter which imprints ink from an inked print ribbon onto a substrate. The imprinter includes multiple printhead assemblies, with one or more heater elements, mounted on a frame. An actuatable backup assembly, also mounted on the frame, corresponds to each printhead assembly, wherein the backup assemblies are actuatable in series or parallel, to move, from a rest position, toward the printhead assembly, to an imprint position, to transfer ink from the print ribbon onto the substrate. A temperature probe disposed in each printhead is coupled to the control unit, which individually and sequentially energizes the heater elements of the respective printheads so that only one printhead assembly is energized at any one time. A spring biased dancer assembly having a idler roller maintains a tension on the inked print ribbon as the inked print ribbon is transferred from a supply reel to a rewind reel. The dancer assembly is coupled to a first encoder which controls a drag brake on the supply reel based on a position of the dancer assembly. A second idler roller is coupled to a second encoder for measuring the rate at which the ribbon is transferred from the supply reel to the rewind reel. The control unit increments the inked print ribbon a short interval to move an unused portion of the inked print ribbon between the printhead and backup assemblies, and then, after a subsequent imprint, increments the print ribbon a long interval to move an unused portion of the ribbon between the printhead and backup assemblies.
摘要:
A message holder for use in vehicles or home or other building windows or the like provides for the display of a message inserted therein. The holder is formed of at least one sheet of transparent material and contains a central space in which a message, such as a bumper sticker, may be temporarily installed for display. Suspension rods are pivotally attached to opposite ends of the holder and have suction cups to provide for the attachment of the holder to any suitable surface. The suspension rods may be locked at any desired angle in order to allow a message displayed within the holder to be seen clearly even through a sloped window, as in the rear window of many vehicles. The holder provides for the temporary display of a bumper sticker or other message as desired without the need to adhesively secure the sticker to a surface and the resulting difficulty of subsequent removal and possible marring of the finish. An alternative version includes suction cups on attachment lugs extending from each end of the holder.
摘要:
A programmable logic device (PLD), such as a field programmable gate array (FPGA), has a programmable clock manager (PCM) that converts an input clock into at least one output clock and the PCM can perform one or more delay-locked loop (DLL) functions. In one embodiment, the DLL functions include clock delay, duty-cycle adjustment, and clock doubling, where duty-cycle adjustment can optionally be applied independently to the doubled clock cycles.
摘要:
A programmable logic device (PLD), such as a field programmable gate array (FPGA), has a programmable clock manager (PCM) that converts an input clock into at least two different output clocks having different clock rates. The different output clocks can be used to control different processes either within or outside the FPGA. For example, one output clock can be used to control the FPGA's input/output registers, while a second, faster output clock can be used to control the FPGA's internal registers.

A remote control system for a vehicle mirror comprises a pair of drive systems each having a nonrotatable actuator shaft (12) caused to move longitudinally by an internally threaded bore (52) of a pinion gear (14) in driving engagement with a worm gear (16) on a shaft of a motion (18). The actuator shaft (12) is divided by a slot (36) into two end portions (38, 39). The first end portion (38) has a threaded protrusion (42) and the second end portion (39) has an unthreaded protrusion (44). Both end portions additionally spring biased (40). The actuator shaft (12) is made of flexible plastic so that the shaft flexes as the mirror pivots with respect to the motor housing (10).
