Title: Hot-bar suspension system
Inventor: PORTERFIELD RICHARD F
IPC: B23K3/00
Filed: 1990-08-15
Abstract: ABSTRACT OF THE DISCLOSURE Compensation is made for inherent lateral  shifting of portions of a pivoted working surface along a work surface, when the pivot point of the working surface is maintained on a line of feed into contact with said work surface, during  relative  pivoting  of  said  working  surface  into conformity with said work surface.  The working surface is supported by a quadrilateral linkage system having a remote instantaneous center point which, during pivoting of the working surface, is maintained substantially on a quiescent centerline of the linkage system.   By spacing the pivot point of the working surface from this center point along the centerline, the pivot point is caused to move laterally of the centerline during exercising of the linkage system The distance and direction of spacing the pivot point from the center point is selectable so as to cancel the inherent lateral shifting referred above.  A preferred embodiment of the invention maintains the working surface in the tilted position  of  conformity  with  the  work  surface  during subsequent withdrawal of the working surface therefrom.

Title: Refrigeration system having a modulation valve which also performs function of compressor throttling valve
Inventor: HANSON JAY L
IPC: F25B47/02
Filed: 1990-11-21
Abstract: 55,492 ABSTRACT OF THE DISCLOSURE A refrigeration system having a modulation valve which controls  refrigerant flow to a compressor according to  a  control  algorithm.    The  need  for  a compressor throttling valve  is eliminated  by a load control circuit which  operates  the  modulation  valve  to   perform  the function of  the throttling  valve when  load reduction is required.  An overload  condition  of  a  compressor prime mover  overrides  the  control  algorithm  and  selects  a predetermined  load  control  position  of  the modulation valve.  A timer ensures that a predetermined recovery time is  provided,  before  switching   back  to   the  control algorithm.    The  timer  also  selects  the  load control position of the modulation valve upon start-up.  A heating or  defrost  mode  automatically  selects the load control position of the modulation valve for  the duration  of the mode, as  does an  ambient air temperature sensor when the ambient exceeds a predetermined value.

IPC: A61B17/22
Filed: 1991-01-10
Abstract: The guide catheter system for use in the treatment of coronary artery disease includes a first single-lumen catheter of a relatively large internal diameter to pass a second guide catheter therethrough.   The first guide catheter comprises an elongated flexible tube having a stainless steel braid embedded in the wall  thereof  for  imparting  desired  torqueability characteristics to it.   The first guide catheter is intended to be inserted at an appropriate point in the vascular system and then advanced until its distal end reaches the coronary ostium.  The second guide catheter is  fabricated  by  extruding  a  plastic,  such  as polyurethane thermoplastic resin over a tubular Teflon? core and because it is to be used within the lumen of the first catheter,  it need not include a braided structure within its walls to prevent it from kinking. This allows the second catheter to be sufficiently slim to permit it to be advanced into a coronary artery while allowing fluids to be perfused between the outer wall of the second guide and the inner wall of the first  guide  catheter  while  still  providing  a sufficiently  large  inner lumen to pass  a working catheter, e.g., an angioplasty or atherectomy catheter. An atraumatic tip is attached to the distal end of the second guide catheter.

Title: Sanitary facility for cats
Inventor: REINARTZ JOHANN O
IPC: A01K1/01
Filed: 1991-07-10
Abstract: ABSTRACT 1) designation Sanitary facility for cats (toilet facility for cats) 2) Abstract 2.1) The advantage of this toilet for cats relative to conventional models consists of the fact that the toilet automatically cleans itself after each use and is again automatically supplied with fresh cat litter. Annoying odors are extensively eliminated by that the used cat litter is immediately removed into a separately mounted, air tight waste container equipped with a replaceable bag, by a slide. This satisfies both the hygienic requirements of contemporary household pet maintenance and the cleanliness needs of cats. 2.2) The problem is resolved by that a slide is located in the cat toilet facility, which moves the used cat litter into an automatically opening and closing waste container and that subsequently fresh cat litter is distributed over the bottom by an automatic refill device.  To prevent access to the toilet facility during the cleaning process, the inlet is closed by a sliding door.

Title: Method and apparatus for fast page mode selection
Inventor: MEHRING PETER A
IPC: G06F12/0882
Filed: 1991-11-28
Abstract: ABSTRACT OF THE INVENTION   In the memory access unit of the present invention, the memory request logic is centralized in the memory management unit (MMU). The MMU instructs the MCU, which interfaces directly with the DRAMs, on the type of memory access to perform. By centralizing the memory requests, the MMU is able to maintain an account of each memory access, thereby providing the MMU the means to determine if a memory access fulfills the requirements of a fast page mode access before a request is made to the MCU. The MMU comprises the row address comparator which can execute the row address comparison in parallel with the cache lookup. Therefore, if the cache lookup determines a memory access is required, a specific fast page mode memory access request can be made, without the memory controller incurring the additional delay of checking the row address. Thus, by using the memory access unit of the present invention, the system can default to fast page mode access without the additional penalty normally incurred by comparing the row address in a serial manner.
