Patent CA-2123448-A1 (CA)
Inventor: RAY DAVID S
IPC: G06F9/46
Filed: 1994-05-12
Abstract: An apparatus and method provides additional logic in both execution units of a dual execution unit processing in order to   determine   if the   instruction   is   interruptible.          Additionally,  backout  logic is  provided  for  saving  the contents of unique registers.  The backout logic uses two decodes to determine if the instruction currently executing modifies the unique registers.  It is possible for a single instruction to modify more than one unique register.  The backout logic of the present invention resides in both of the execution units and particularly in the unit which contains the  unique  register  being  modified  by  the  executing instruction.  If  an  instruction  is  being  executed  which modifies one of the unique registers, then the contents of that register are saved in a backout latch. A cancel signal is then  provided  if  the  interruptible  instruction  executes without causing and interrupt. However, if the interruptible instruction does cause an interrupt, then the contents of the backout latch are reloaded into the execution units.

IPC: B41J2/14
Filed: 1994-06-06
Abstract: An ink jet printing head that, based on the face shooter principle, contains a nozzle row arranged in the z-direction in the surface of a plate, allowing an ink jet to be ejected in the y-direction, a membrane plate arranged on a first chamber plate carrying the ink chambers, and paths for delivering and actuators for expelling ink from each chamber. The ink jet printing head also has a second chamber plate in a different level from the first chamber plate. The chambers of the second chamber plate are arranged offset in the x- and z-directions relative to the chambers of the first chamber plate. The overlap of chambers of neighboring levels becomes minimal as a result. Alter a pre-treatment of the plate material of which the printing head is constructed, a masking and etching of the plates ensues in a parallel plate processing for all individual parts.  Separated, finished discrete parts are joined and contacted to form a module.
Patent CA-2126100-A1 (CA)
Inventor: KNUDSON GARY A
IPC: B21J15/04
Filed: 1992-11-30
Abstract: Fastening apparatus and method for forming a rivet-type fastener are disclosed for joining two pieces together that is particularly suitable for use in constructing a building. The fastening apparatus (14) utilizes an actuating rod (22) preferably driven by a hydraulic cylinder (15) with the rod being inserted through a fastening section (67) and holes (71) in pieces to be fastened. A  set of dies (51,57) has one fixed (51) and one pulled (57) by the rod through the holes to form at least one rolled flange or two rolled flanges (78) to form a hollow fastener that secures the pieces together. The rod is automatically returned to an extended position to be ready for the next operation. The fastener has a relatively large inside diameter in relation to the thicknesses of the pieces being fastened to avoid shear of the piece and prevent having the flange deform under load.

Title: Stabilization of cultured skim bactericidal activity
Inventor: NAUTH KAISER R
IPC: A23C9/123
Filed: 1994-06-30
Abstract: The present invention is directed to a method for retaining the antimicrobial activity of the byproducts of growth of microorganisms during storage. In the method, a pasteurized low fat or skim milk substrate is provided. The substrate is inoculated with an S.lactis culture. The substrate is then fermented to cause growth of the culture and the release of metabolic byproducts, including nisin, from the culture. The fermented substrate is loaded into a container. The headspace of the container is then flushed with a quantity of an inert gas in excess of the amount required to displace all of the ambient air in the headspace. In an important embodiment of the invention, a small amount of a CO2 producing chemical, such as calcium carbonate, sodium carbonate and sodium bicarbonate, is mixed into the fermented substrate. The CO2 producing chemical has the effect of both stabilizing the antimicrobial activity of the cultured substrate and aiding in the release of nisin from the cells produced during fermentation of the substrate.

Inventor: FADYK MICHAEL W
IPC: B27C9/00
Filed: 1994-08-12
Abstract: The conventional method of producing wooden rosettes involves the lowering of a cutting tool against a square blank clamped on a worktable.  The method is time consuming and labour intensive and, because the cutting tool is moved vertically against the workpiece, tool misalignment can occur.          A simple machine for facilitating the production of rosettes which are consistent in terms of shape includes a frame with a worktable mounted for vertical movement thereon, a clamp system for releasably clamping a blank on the worktable, a rotary cutter head mounted on the frame above the worktable, and a piston/cylinder for moving the worktable vertically, whereby the blank can be moved against the rotating cutter head mounted on the frame above the worktable, and a piston/cylinder for moving the worktable vertically, whereby the blank can be moved against the rotating cutter head to form a rosette, and an ejector air cylinder for ejecting a completed rosette.

Title: Film cartridge loading apparatus for camera
Inventor: LAWTHER JOEL S
IPC: G03B17/30
Filed: 1995-02-10
Abstract: A camera is provided with a loading chamber insertion mechanism for receiving a film cartridge of the type having a retention slot formed therein inserted manually into an insertion position by positively engaging the retention slot, pulling the cartridge into the chamber, and seating the cartridge in a seated position.  A movable clamp and escapement mechanism are operable in an initial, insertion position for latching a carriage against movement in response to a biasing force provided by a tensioning spring.  The movable clamp is pivotally mounted to the clamp for movement within escapement channels that cooperatively latch the carriage in the insertion position.  The clamp pivots on the carriage within the escapement channels on being contacted by the film cartridge during its initial end-wise insertion by the user.  The clamp pivots in the escapement channels to an intermediate, unlatched position that releases the carriage for movement in response to the biasing force and simultaneously engages the film cartridge retention slot.  The carriage and clamp are pulled by the spring biasing force through the escapement channels and in turn pull on the engaged film cartridge to effect seating of the film cartridge in the loading chamber.
