Title: Method and apparatus of isolating pneumatic panels in liquid application systems
Inventor: KONIECZYNSKI RONALD D
IPC: G05D16/00
Filed: 1991-02-07
Abstract: METHOD AND APPARATUS OF ISOLATING PNEUMATIC PANELS IN LIQUID APPLICATION SYSTEMS          Abstract of the Disclosure A method and apparatus for applying liquid coating  materials,  adhesives  or  other  liquids  is provided in which the liquid material is pumped from a source through a pneumatically operated,  diaphragm-type pressure regulator which discharges the liquid at a controlled pressure to a dispenser such as a spray gun.  Pressurized air from a pneumatic panel or other air supply device is transmitted to one side of the diaphragm in the pressure regulator through a one-way valve such as a check valve which protects the pneu-matic panel from an upstream flow of liquid from the pressure regulator in the event of a failure of its diaphragm.  A fluid bleed device such as a choke is located downstream from the check valve and upstream from the diaphragm in the pressure regulator to vent pressurized air located therebetween,  and to permit the escape of at least some of the liquid  flowing upstream from the pressure regulator in the event of a failure  of  its  diaphragm  which  provides  a  visual indication of the failure of the diaphragm.

Title: Granularity hint for translation buffer in high performance processor
Inventor: SITES RICHARD L
IPC: G06F12/10
Filed: 1991-06-27
Abstract: GRANULARITY HINT FOR TRANSLATION BUFFER      IN HIGH PERFORMANCE PROCESSOR                 ABSTRACT OF THE DISCLOSURE       A high-performance CPU of the RISC (reduced instruction set) type employs a standardized, fixed instruction size, and permits only simplified memory access data width and addressing modes.  The instruction set is limited to register-to-register operations and register load/store operations.  Byte manipulation instructions, included to permit use of previously-established data structures, include the facility for doing in-register byte extract, insert and masking, along with non-aligned load and store instructions.  The provision of load/locked and store/conditional instructions permits the implementation of atomic byte writes.  By providing a conditional move instruction, many short branches can be eliminated altogether.  A conditional move instruction tests a register and moves a second register to a third if the condition is met; this function can be substituted for short branches and thus maintain the sequentiality of the instruction stream. Performance can be speeded up by predicting the target of a branch and prefetching the new instruction based upon this prediction; a branch prediction rule is followed that requires all forward branches to be predicted not-taken and all backward branches (as is common for loops) to be predicted as taken.  Another performance improvement makes use of unused bits in the standard-sized instruction to provide a hint of the expected target address for jump and jump to subroutine instructions or the like.  The target can thus be prefetched before the actual address has been calculated and placed in a register.  In addition, the unused displacement part of the jump instruction can contain a field to define the actual type of jump, i.e., jump, jump to subroutine, return from subroutine, and thus place a predicted target address in a stack to allow prefetching before the instruction has been executed.  The processor can employ a variable memory page size, so  hat the entries in a translation buffer for implementing virtual addressing can be optimally used.  A granularity hint is added to the page table entry to define the page size for this entry.  An additional feature is the addition of a prefetch instruction which serves to move a block of data to a faster-access cache in the memory hierarchy before the data block is to be used.

Patent CA-2047362-A1 (CA)
Inventor: HIRSCH MARTIN
IPC: C10J3/84
Filed: 1991-07-18
Abstract: The process gases are passed into a steady-speed fluidised bed designed as an annular trough and fitted with cooling elements. Fluidising gas is passed into the fluidised bed through the inflow tray of the trough. The process gas is introduced through the central orifice of the fluidised bed. Cooled solid flows out of the fluidised bed over the inner rim of the trough into the process gas stream and is carried along by the latter into the dust chamber above the surface of the fluidised bed. The solid deposited in the dust chamber drops back into the annular fluidised bed, and the cooled gas containing the residual solid is passed into a gas cooler fitted with cooling surfaces. The gas emanating from the upper part of the gas cooler is passed into a dust precipitator, and the precipitated solid is recycled into the steady-speed fluidised bed.

Abstract: METHOD AND APPARATUS FOR THE MANUFACTURE               OF A LAMINATE OF TWO METAL SHEETS AND            A THERMOPLASTIC MATERIAL LAYER BETWEEN THEM     ABSTRACT OF THE DISCLOSURE          A laminate of two metal sheets and a layer of thermoplastic material is made by moving the two sheets along respective paths so that they approach each other at a region of convergence and feeding extruded thermoplastic material into the region of covergence so that the material is squeezed between the converging sheets to form the layer adhering to said sheets.  To improve bond strength, and reduce bonding time, an extruding nozzle for the thermoplastics material of slot shape is located relative to the region of convergence so that a body of said thermoplastics material in flowable state is formed in the convergence region in contact with the sheets, the layer being continuously drawn from the body and the body being replenished by extrusion from the nozzle.  The body is wider than said extrusion slot as seen in section in the width direction of the slot.     (Fig. 6)

Abstract: ABSTRACT      An image area is refreshed during the transmission of a set of motion compensated sequential video images.  The video images are divided into a plurality of adjacent regions.  The image area is refreshed during a refresh cycle by communicating a different region in each successive video image of the set without motion compensation. Motion compensation of the previously refreshed regions of the image area during the refresh cycle is restricted to an area containing only the previously refreshed regions.  Video image data from a current region being refreshed is encoded for use by a decoder in identifying it as non-motion compensated data.

Title: Explosive pipe crimping method and devices
Inventor: HUDAK DAVID
IPC: F42D1/00
Filed: 1992-04-24
Abstract: "EXPLOSIVE PIPE CRIMPING METHOD AND DEVICES"                  ABSTRACT OF THE DISCLOSURE     A main charge of explosive is positioned symmetrically about a passageway-forming tubular member, such as a well pipe assembly.  The charge is outwardly and radially spaced from the member and is coupled thereto by a dense medium, such as soil, which is adapted to transfer the produced explosive energy to the tubular member in the form of a pressure pulse applied by the medium.  Initiation charges are supplied at the outer surface of the main charge, to initiate a detonation wave directed at the tubular member.  A layer of dense medium is provided to confine the non-coupled surface of the charge and retard venting of explosive gases away from the tubular member.  In the end result, concentrated,  converging pressure pulses are applied to the tubular member on detonation, to cause it to be symmetrically crimped to restrict the passageway.
