Title: Side shift railway guide wheel apparatus
Inventor: MADISON HARRY
IPC: B60F1/00
Filed: 1991-11-19
Granted: 1997-09-30
Abstract: A railway guide wheel apparatus attaches to a frame of a road vehicle to allow the road vehicle to travel along rails.  The apparatus has a side shift capability where railway wheels of the apparatus may be lowered to engage rails even when the vehicle is offset sideways from the rails.  An automatic centering arrangement will center the vehicle relative to the rails after the railway wheels have engaged the rails.  Spring cells are used as a suspension to absorb vibration from the railway wheels contacting the rails and to maintain the railway wheels in contact with the rails.

Title: Method and circuit for testing transmission paths
Inventor: GAUTHIER JOHN ALBERT
IPC: H04B17/309
Filed: 1991-12-11
Granted: 1998-12-29
Abstract: A circuit for testing the integrity of transmission paths includes a first linear feedback shift register (LFSR) adapted to generate a periodic sequence of pseudo random test data for transmission on the transmission paths.  A second LFSR synchronizes to the transmitted test data after being provided with a seed value corresponding to a transmitted data word.  After synchronization, the second LFSR is set to a free running mode and independently generates a pseudo random sequence of patterns corresponding to the sequence generated by the first LFSR.  A comparator compares the pseudo random data generated by the second LFSR with the pseudo random data received from the transmission paths.  If a mismatch occurs a signal indicating an error condition is asserted.

Granted: 1999-01-26
Abstract: This interface connection through a hole (2) in a high-temperature-resistant and vacuum-proof insulating part (1), particularly of ceramic, glass, or a single crystal, consists of a metallic Lead (4, 17) inserted into the hole (2) and having a coefficient of thermal expansion less than that of the insulating part (1), wherein at least one end of the lead, if it is flush with at least one surface of the insulating part, is covered with active brazing material which high-vacuum-seals it to the insulating part, or, if it projects beyond at least one surface of the insulating part, is high-vacuum-sealed to the insulating part by means of ring-shaped active brazing material (5'), since in the liquid phase, the active brazing material moves into the gap between the wall of the hole (2) and the lead (4, 17) due to  capillary action. Thus, the available materials (insulating material, metals having a smaller coefficient of thermal expansion than the insulating part, active brazing materials) can be used in a different and novel manner such that the use of a lead covered with active brazing material can be dispensed with.

Title: Bumper assembly with resilient bumper for shopping cart
Inventor: KINNAMON KEVIN DALE
IPC: B62B5/00
Filed: 1992-05-19
Granted: 1999-06-15
Abstract: A bumper assembly for a shopping cart having a wire basket with horizontal wires bent so as to define a front corner of the basket.  The assembly comprises a resilient, extruded, polymeric bumper having front, back, and side apertures extending longitudinally through the bumper, which is slotted so as to accommodate such wires at the front corner.

Title: Personal computer having memory system with write-through cache and pipelined snoop cycles
Inventor: DERWIN MICHAEL THOMAS
IPC: G06F12/08
Filed: 1992-08-27
Granted: 1996-10-22
Abstract: A personal computer has a memory system including a write-through cache which is accessible by more than one device. A snoop mechanism includes logic that monitors bus master control signals to determine if a new memory write cycle has been started before a current snoop cycle has finished. If a new cycle has been started, then a corresponding snoop cycle occurs which overlaps the new memory cycle and is pipelined with the previous snoop cycle so that the snooping mechanism does not fall behind the memory write cycles.

Abstract: A system for cooling a single or plural zones of the exterior of a furnace or similar hot device, e.g., kiln, calciner, etc.   Each zone is cooled by a respective cooling assembly.   The operation of the assemblies is effected by a common control system.   Each cooling assembly comprises a shroud,  an induction cooler, e.g.,  an exhaust fan,  and at least one atomizing spray nozzle.  The shroud is in the form of a jacket disposed over the associated exterior zone of the furnace and is spaced therefrom to form a cooling chamber therebetween.   The exhaust fan is coupled to the shroud for inducing the flow of cooling air through the cooling chamber so  that  it  absorbs  heat  from  furnace's  exterior.    The atomizing spray nozzle is also coupled to the shroud and to a water and an air supply for introducing atomized droplets of water into the chamber, whereupon the droplets vaporize to absorb heat from the furnace's exterior.  The exhaust fan vents the air and steam from the shroud means.  A controller controls the operation of each cooling assembly pursuant to feed-back signals from respective thermal sensors mounted in each cooling assembly.
