Title: Method for regulating the temperature of an adjustable-crown roll and regulation system intended for carrying out the method
Inventor: NISKANEN JUHANI
IPC: D21G1/02
Filed: 1990-05-14
Granted: 1998-08-11
Abstract: The invention concerns a method and apparatus for regulating the temperature of an adjustable-crown roll.  The roll mantle (12) arranged to revolve on the stationary axle (11) of the roll (10) is loaded by passing a pressure medium into a pressure chamber (15) or series of chambers formed between the axle (11) and the mantle (12) so as to correct the deflection of the roll mantle (12).  The roll (10) is additionally heated/cooled by passing heating/cooling fluid into the roll (10).  The heating/cooling fluid used for the regulation of the temperature of the roll (10) is introduced into the roll (10) so as to be substantially uniformly distributed over the surface area of the roll (10) such that heat is removed or produced in the radial direction of the roll.  The heating or cooling fluid is passed into the pressure chamber (15) in the roll (10), in which case, by its means, pressurization of said chamber (15) is also accomplished, and/or into the unpressurized chamber (16) of the roll (10), in which case the function of the fluid is exclusively regulation of the temperature.  The invention further concerns a regulation system for carrying out the method.

Filed: 1990-07-18
Granted: 2000-09-05
Abstract: Foodstuffs are coated with particulate material wherein the foodstuff is delivered onto a conveyor onto which the particulate material falls to coat the upper surface of the foodstuff. The partly coated foodstuff is passed to another conveyor and in the gap between the two conveyors particulate material is brought from below and which coats the underside of the foodstuff as it passes onto the other conveyor. The foodstuff fully coated is then conveyed to storage. Excess particulate material falls into a circular rotating drum through which the conveyors pass and is lifted by the rotation of the drum to fall into a hopper and thence to be made to fall upon the top of the foodstuff as described.   Part of the particulate material falling onto the foodstuff is allowed to pass through a gap between the conveyors, or gaps in one of the conveyors, to be directed to an upwards moving conveyor to provide that for coating the underside of the partially coated foodstuff.

Title: General purpose compound apparatus for instruction-level parallel processors
Inventor: EICKEMEYER RICHARD J
IPC: G06F9/30
Filed: 1991-03-07
Granted: 1998-01-20
Abstract: The  disclosure  deals with a  technique  for  generating compound instructions from a binary instruction stream without knowledge as to where instructions start or which bytes  contain  data  instead  of   instruction. The disclosure describes pre-processing a set of instructions (or a program) to determine statically which instructions may  be  combined  into  compound  instructions.   Such processing is done in a typical embodiment by software and/or hardware means which will  look for classes of instructions  that  can  be  executed  in  parallel  in  a particular    computer    system   configuration.     The instruction  classes  and  the  compounding  rules  are implementation specific and will vary depending on the number and type of functional execution units.   While keeping their original sequence and object code intact, individual  instructions  are  selectively  grouped  and combined  with  one  or  more  other  adjacent  scalar instructions to form a compound instruction byte stream having both compounded scalar instructions for parallel execution  and  non-compounded scalar  instructions  for execution  singly.   Control  information is  appended to identify information relevant to the execution of the compound instructions.

Title: Very high angular resolution laser beam rider detector
Inventor: DUBOIS JACQUES
IPC: G01S7/483
Filed: 1992-06-18
Granted: 2000-04-11
Abstract: A laser warning receiver (LWR) having an ability to not only detect a low power level laser source, such as a pulse train emitted by a laser beam rider, but to also provide a high angular resolution in determining the angle of arrival of that pulse train. The receiver includes a lens/filter arrangement for a large area photodetector to detect an incoming signal from an emitting source and a high gain amplifier to amplify the signal which is then applied to a synchronization generator that generates a digital pulse train with pulses corresponding to peaks in the incoming signal. The digital pulse train is applied to a code breaker where the code is analyzed and a further code is generated anticipating the arrival of further pulses in order to verify the code. That further code is applied to a time gate generator which generate a code, synchronized with the incoming signal, that controls the high voltage of a gated image intensifier which is coupled to a video camera. Gating of the image intensifier is synchronized, as a result, with coded emissions from the source so that a video image from the camera can be displayed on a monitor and more easily differentiated from the background. The width of pulses generated by the time gate generator, the video camera, gain of the gated image intensifier, gain of the gated image intensifier and an auto-iris zoom lens coupled to the image intensifier are all under the control of a video processor.
