Title: Extincteur de cigarettes
Inventor: FRANCHELLINI ANTONIO RUE SAINT
IPC: A24F19/14
Filed: 1978-04-25
Granted: 1981-02-03
Abstract: L'invention concerne un dispositif extincteur de cigarettes fixé sur le rebord d'un cendrier.  Le dispositif comporte deux lames pivotées entre leurs bouts sur un axe commun monté sur le rebord du cendrier, chacune munie d'un tranchant permettant de couper le bout d'une cigarette, des moyens pour rappeler les lames dans une position ouverte, et un couvercle recouvrant les tranchants et muni d'un trou dans lequel la  cigarette peut être insérée pour être tranchée par les tranchants des deux lames.  Celles-ci sont actionnées en les serrant par exemple entre le pouce et l'index, ce qui permet de se servir de l'autre main pour tenir la cigarette que l'on veut éteindre, étant donnée qu'il n'est pas nécessaire de retenir le cendrier.

Abstract: MEATY TEXTURED PET FOOD ABSTRACT OF THE DISCLOSURE Disclosed is a uniquely textured pet food in the form of low-intermediate moisture, but highly-palatable, resilient, soft, meat-like chunks. These soft, chewy chunks are expanded internally and have a substantially-continuous, fibrous, highly-irregular surface. This pet food is prepared by relatively high pressure extrusion of a plasticized, meat based formulation to achieve expansion. The product contains sufficient water activity (aw) lowering and antimycotic agents to avoid spoilage when packaged under aerobic conditions. By virtue of their meat-like texture and structural integrity, these chunks enable the production of an unusually good quality dual-textured pet food.

Abstract: ABSTRACT     A metal panel, particularly though not exclusively for use as an outer panel of a refrigerator door or hinged freezer lid, has a peripheral lip forming an inwardly facing channel.  The channel is formed by two folds, the outer fold being formed by roll-forming operations and the inner by a folding machine or the like.  This (a) permits the panel forming machine to be more readily adjustable for different sizes of panels, (b) permits the lip to be made up of a number of folds (which strengthens the panel and permits thinner metal to be used), (c) avoids the need for corner welding, (d) permits a lip profile into which a gasket can be snap-fitted and (e) permits precoated metal sheet to be used.

Abstract: SYSTEM FOR RANDOMLY ACCESSING    A RECIRCULATING MEMORY              Abstract of the Disclosure A control system for randomly accessing the contents of a recirculating shift register memory under the control of a processor.  The processor provides to the control system an address equivalent to the number of positions the operating point (defined by an operating flag) is to be moved in the shift register memory to access the information desired by the processor.  The control system decodes the address, removes the operating flag from the memory character stream and reinserts the operating flag in the memory at the point desired by the processor during a single revolution of the memory.

Title: Galois field computer
Inventor: BERLEKAMP ELWYN R
IPC: H03M13/15
Filed: 1979-04-19
Granted: 1982-03-30
Abstract: ABSTRACT Errors are corrected in a cyclic encoded data stream, consisting of sequential groups of data bits and check bits, by means of a novel digital computer.  The computer employs a stored program and is organized into three distinct substructures, each having an independent internal addressable memory and all capable of synchronous concurrent operation. An arithmetic unit substructure (6) including a data memory (60) implements finite field arithmetic operations upon received data.  The arithmetic unit includes a Galois field manipulative subunit (62) for producing finite field products and sums over the field GF(25) from operands selected from three registers which derive data from the memory of the arithmetic unit, another register, or the result of a currently executed Galois field operation.  The preferred embodiment is especially suitable for correcting data encoded in the Reed-Solomon(31,15) code.  An address generator (5) realizes address modification in the Galois field GF(27), whereby consecutive addresses in data memory (60) are characterized by a shift register sequence.  The address generator (5) includes a counter memory array (52) and an equality test facility (54).  Counter memory words of the address generator may selectably retain either the modified or non-modified address.  A control unit substructure (4) includes a control memory for storage and execution of the instruction sequence, branching logic (44) for determining the transfer of control in response to logical functions of up to 16 logical variables, and select means and gating means for execution of instructions in all three substructures. Provision for data dependent arithmetic function selection, not employed for decoding the (31,15) Reed-Solomon code, permits operation of the apparatus to yield solutions at high speed to simultaneous linear binary equations.
