Patent CA-1310520-C (CA)
Inventor: COOPER DAVID G
IPC: F16H57/021
Filed: 1988-01-21
Granted: 1992-11-24
Abstract: ABSTRACT          A clip to clip independently rotatable parts that must be axially held relative to each other, but not be constrained from sliding axially together.  Each part (9, 10) has a bore and an internal annular groove (28) and the clip has transverse flanges (23, 24) that spring out and enter the grooves when the bores are aligned.  The clip has a gap so that the cross-section can be changed considerably by gripping holes in the flanges with long-nosed pliars, or other gripping tool, that can enter the internal bores, address the clip to the grooves, and release the clip to enter the grooves. The tool is also used to remove the clip for dissembling the parts.  Thus the parts, eg mainshaft gears, that have to be slide each way to engage respective dogs, can be replaced individually - in contrast to existing gear-pairs which tend to be unseparable without destruction of the clip (and usually of both gears).

Granted: 1992-06-16
Abstract: ABSTRACT OF THE DISCLOSED EMBODIMENT A sheet feeder for a copier for the sequential separation and feeding of individual sheets from a stack of sheets with an impact type sheet feeder with flexible frictional flapper blades, a preprogrammed drive for automatically moving the sheet stacking tray towards or away from the sheet feeder, a reference stop automatically limiting the movement of the top of the stack relative to the feeder, and a programmed positioning mode for automatically slightly lowering the tray into an optimum feeding position in which the top of the stack is maintained at a substantially constant level position relative to the feeder, closely adjacent, but slightly spaced below, the limit position, and automatically programmed repositioning to maintain the optimum feeding position and to compensate for the reduction in the height of the stack as sheets are fed, and to provide improved double sheet feed prevention by cycling the tray though small up and down movements coordinated with the feeding of sheets from the stack, for moving the fed sheet into and out of engagement with retard members. Retarding is further assisted by angled take-way rollers deflecting the trail end of the fed sheet down against the next sheet.

Abstract: METHOD AND APPARATUS FOR MANAGING MULTIPLE LOCK INDICATORS IN A MULTIPROCESSOR COMPUTER SYSTEM                            Abstract A computer system having multiple processors inter-connected by a pended bus provides exclusive read-modify-write operations employing multiple lock bits.  A processor generates an interlock read command which is transmitted as a transfer over the pended bus to a memory or I/O node.  Acknowledge con-firmations are transmitted by the memory back to the processor two bus cycles after each bus cycle of the processor transfer. The processor transfer, including an interlock read command, is stored in a input queue in memory and processes in turn by the memory.  A first interlock read command to a specified memory location causes a lock bit to be set for that location and a first type of response message including the contents of the specified location to be generated by the memory and stored in an output queue.  The memory obtains access to the pended bus through an arbitration process and transmits a response message including the contents of the memory location specified in the interlock read command at an unspecified time after initiation of the interlock read command.  A subsequent interlock read command from the processor to the same memory location will result in a denial of access to the specified location and in the generation of a second type of response message by the mem-ory which indicates that the specified location is locked.

Abstract: ABSTRACT    A net shaped ceramic-reinforced aluminum matrix composite is produced by forming a permeable mass of ceramic material with a defined surface boundary having a barrier, and contacting a molten aluminum-magnesium alloy with the permeable mass of ceramic material in the presence of a gas comprising from about 10 to 100% nitrogen, by volume, balance nonoxidizing gas, e.g. hydrogen or argon.  Under these conditions, the molten alloy spontaneously infiltrates the ceramic mass under normal atmospheric pressures until it reaches the barrier.  A solid body of the alloy can be placed adjacent to a permeable bedding of ceramic material having a barrier, and brought to the molten state, preferably to at least about 700 C, in order to form the net shape aluminum matrix composite by spontaneous infiltration.  In addition to magnesium, auxiliary alloying elements may be employed with aluminum.  The resulting composite products may contain a discontinuous aluminum nitride phase in the aluminum matrix.

Abstract: "CONTROLLED DEFLECTION OF FLEXIBLE SCRAPER STRANDS"            Abstract A conveyor belt scraper assembly includes an array of   transversely  extending,   flexible   scraper   members engaging, in an operative position, a conveyor belt surface to be cleaned.  The flexible scraper members are resiliently biased in frictional engagement with the curved surface of the conveyor belt by a tension spring.  Each scraper member includes a flexible tension member, a plurality of scraper blades movably coupled to the tension member,  and spacer springs  yieldably  separating  the  scraper  blades.    The scraper blades are differently sized relative to each other to impose different static deflections at separate points along the flexible tension member relative to the conveyor belt surface.  According to this arrangement, the deflection forces are shifted to the scraper blades along the trailing end of the cable, thereby avoiding a concentration of forces on the leading scraper blade which could lead to premature wear and breakage of the tension member.

Abstract: ABSTRACT     A pair of frame members are secured to the ends of a pair of adjacent generally circular ducts.  Each frame member includes a vertical wall extending upwardly from the circular duct and a sloped outer wall angularly spaced from the vertical wall.   Each frame member includes an annular pocket for receiving an end of the circular duct, and a base wall abutting the annular pocket.  The base wall has a rebent end portion for engaging a plurality of protuberances positioned on the inside wall of the circular duct.   The frame members have an expanding means to urge the frame end portions away from each other to increase the diameter of the frame and engage the duct end portion.  A gasket is positioned between the vertical walls of adjacent frame members to contact the adjacent vertical walls, and a clamp is positioned in surrounding relationship with the pair of adjacent frame members secured to the pair of adjacent circular ducts.  The clamp has a pair of legs, each leg contacting a frame member sloped outer wall.  The clamp includes tightening means for reducing the diameter of the clamp.  As the tightening means is operated to reduce the diameter of the clamp, the clamp legs are moved in a direction towards the adjacent circular ducts to slide along the adjacent frame members sloped outer walls.  As the legs are moved along the adjacent sloped outer walls, the pair of adjacent frame members are urged towards each other and into further contact with the gasket to provide an air-tight connection between the circular ducts.

Abstract: ABSTRACT OF THE DISCLOSURE A hydraulic actuating unit for raising a hospital bed includes a reser-voir, a hydraulic piston cylinder device the cylinder of which has its ends con-nected to the reservoir through a supply conduit that contains a hydraulic plunger pump with suction and pressure valve means and through a return conduit which contains an orifice in a normally closed relief valve. A branch conduit leads to a hydraulic liquid accumulator from the supply conduit at a location between the cylinder and pressure valve means. A multiple pilot op-erated check valve of the differential type is provided in the branch conduit to-wards the accumulator. The largest and smallest end faces of the differential spool member are subject to the pressure in the branch conduit while the dif-ferential area of the spool member is subject to the pressure in a conduit whichleads from the return conduit at a location between the orifice and the relief valve. The pressure in the branch conduit to the accumulator tends to cause the spool member and the check valve to open while the pressure in the return conduit tends to move the spool member into a closed position.
