Abstract: CONTINUOUS SNOW CHAIN                    Invented by:  Hyok Sang Lew Abstract A snow chain for automovile tires employing a single or   a plurality of chains disposed circumferentially around the tire in the zig-zag pattern is disclosed.  In the said arrangement of the snow chain, the tire always rolls on top of the chain and, consequently, a better traction as well as a smoother ride is enhansed.  Further more, said snow chain eliminates the vibration and pounding commonly experienced with the conventional snow chains.  As a consequence, said snow chain enables to drive the car at a higher speed on the snow covered road as well as on the bare asphalt surfaces. The high speed capability of said snow chain is further bolstered by the net-like pattern of said snow chain, which provides the self-centered capability of said snow chain around the tire.

Abstract: ABSTRACT OF THE DISCLOSURE         An expanded pet food product having a moisture content of about 20%-30% by weight and a spongy, compressible cellular structure is made by combining a mix of dry ingred-ients containing farinaceous materials, proteinaceous materials and dry bacteriostatic materials with a blend of liquid ingredients containing an edible acid, a liquified fat or oil, a liquid bacteriostatic agent and water, and passing said admixture  into an expander where it is subjected to mechanical work, shear, heat and pressure. The hot admixture is extruded through a die plate into a zone of lower pressure to cause the extrudate to expand.  As the extrudate passes through the die plate it is cut into particles of desired length and promptly contacted with a water spray to reduce its temperature and control the amount of moisture loss from the particles.  The cooled extrudate particles are coated first with an edible fat or oil and then with a solution containing an antimycotic, water and flavoring material.          The thus coated product is then packaged.

Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus and process for automatically making a spiral wrapped unitary package having a ring type or tied closure.  In the apparatus a series of loads, each containing a plurality of unit are fed one load at a time onto a turntable adjacent a material dispenser with the leading edge of the material from the dispenser being formed into a rope-like configuration by a roper mechanism and held by a clamp mechanism mounted on the turntable. The material is opened to its full web width, stretched and is spirally wrapped around the load at which time it is again formed into another rope-like configuration by the roper mechanism, and is positioned adjacent the leading edge where it is mechanically joined to the leading edge of the material by a ring type or tied closure. The roped material is then released from the clamp mechanism mounted on the turntable and the material is allowed to return to its memory position.  The clamp mechanism again clamps the leading edge for the next load and the material is severed from the wrapped load.

Abstract: HAVING IMPROVED CONTROL SCHEME   ABSTRACT OF THE DISCLOSURE An inverter system for supplying variable frequency alternating current power to a load such as an a.c. motor includes an inverter bridge of controlled rectifiers which are selectively rendered conductive by the application thereto of gating pulses.  The gating signals result from a control circuit which includes a voltage controlled oscillator responsive to a command signal having a d.c. magnitude and polarity which in turn outputs a signal having a substantially saw-tooth wave shape.  Comparator circuits responsive to the saw-tooth wave shape signal provide timing pulses and direction signals which are applied to a shift register to effect movement of the register contents the extant status of which initiates the production of the gating signals for rendering the semiconductors conductive.

Abstract: ABSTRACT            An arrangement for determining when a number of photodetectors each storing charge, in response to electro-magnetic radiation impinging thereon, have on the average accumulated enough charge in a current sample period through the photodetectors having a common electrode at which a voltage is applied commonly and, thereafter, at which a monitoring function takes place.  The monitoring determined when the voltage on the common electrode has sufficiently decreased in response to the electromagnetic radiation impinging on each photodetector to warrant termination of the taking of the current sample as the average accumulated charge has become as large as is desirable.  The arrangement permits determining within the current sample period that the average charge accumulated across the photodetectors in response to impinging electromagnetic radiation thereon has reached as large a value as is desirable without any manipulations of the accumulated charge or delays into later sampling periods such as occurs in the prior art.

Abstract: ABSTRACT OF THE DISCLOSURE         A data processing system which handles thirty-two bit logical addresses which can be derived from either sixteen bit logical addresses or thirty-two bit logical addresses, the latter being translated into physical addresses by unique translation means.  The system includes means for decod-ing macro-instructions of both a basic and an extended instruction set, each macro-instruction containing in itself selected bit patterns which uniquely identify which type of instruction is to be decoded.  The decoded macro-instructions provide the starting address of one or more micro-instructions, which address is supplied to a unique micro-instruction sequencing unit which appropriately decodes a selected field of each micro-instruction to obtain each successive micro-instruction.  The system uses hierarchical memory stor-age using eight storage segments (rings), access to the rings being con-trolled in a privileged manner according to different levels of privilege. The memory system uses a bank of main memory modules which interface with the central processor system via a dual port cache memory, block data transfers between the main memory and the cache memory being controlled by a bank controller unit.
