Abstract: BINARY TO MODULO M TRANSLATION          Abstract of the Disclosure Modulo M translation is performed on a large binary number of n bits by grouping the binary number in contiguous sets of approximately K bits each, storing the modulo M residues for each K bit set in an individually associated pre-stored ROM, reading the modulo M residues for a particular K bit segment of a binary number out of the ROMs, and performing modulo M addition on the read-out residues.  Thus, modulo M translation of a positive number is accomplished in n/k modulo M additions and a table look-up, with the look-up table being stored in n/k ROMs.          A subsequent modulo M subtraction is performed if the binary number is negative.

Abstract: VEHICLE CONSTRUCTION                Abstract of the Disclosure A vehicle having a generally centrally located operator's station with an operator's seat raised above the platform of the operator's station in a rear portion thereof.  An engine is mounted rearwardly of the operator's station with its crankshaft oriented in a fore and aft direction and at least a forward por-tion thereof extending under the operator's seat.  A propulsion pump for a hydrostatic transmission is secured to a rear portion of the engine and has a drive shaft coaxial with and coupled to the crankshaft of the engine.  A PTO gearbox is secured to the rear of the propulsion pump and includes an input shaft which is coaxial with and secured to the drive shaft of the propulsion pump.  The PTO gearbox includes both a rearwardly extending hori-zontally oriented output shaft and a downwardly extending verti-cally oriented output shaft.  The arrangement of components pro-vides a very compact tractor type vehicle in which power from the engine is delivered to both the rear traction wheels and the power take-off output shafts with a very minimum of components.  The arrangement also places an appropriate portion of the weight of the necessary components of the vehicle onto the rear traction wheels to help provide good traction.

Abstract: ABSTRACT OF THE DISCLOSURE: A culture medium composed of carbon source, nitrogen source and minerals was sterilized at 120°C for 15 minutes, inoculated strains of the genus Streptococcus and then cultivated at 35°C for 72 hours under aeration and agitation.  Subsequent of the cultivation, the resultant was subjected to water-washing and sieving to obtain crude glucan.  The crude glucan was then dissolved in NaOH solution and centrifuged.  The recovered filtrate was neutralized with HCl and then the insolubilized glucan was collected by centrifugation.  The collected glucan was washed with water thoroughly until no chloride ion was detected in the waste water and then dried to form white puritied glucan powder.

Abstract: Abstract of the Disclosure A non-caking bleaching composition, based on sodium perborate as the active bleaching component, includes certain proportions of sodium perborate tetrahydrate, water soluble inorganic salts, such as sodium silicate, sodium carbonate and sodium sulfate, and a hydratable molecular sieve zeolite. The presence of the molecular sieve zeolite prevents caking of the bleaching composition upon being subjected to moisture, such as may be released from the sodium perborate tetrahydrate during storage.  Additionally, it furnishes very finely divided insoluble nuclei which may assist in releasing active oxygen from dissolved sodium perborate in aqueous medium during bleaching operations.  Preferably, the bleaching composition is a free flowing parti-culate product, substantially all of which except the sodium perborate tetra-hydrate and molecular sieve zeolite is in spray dried globular bead form.          Also, the product is preferably free of phosphorus.

Abstract: APPARATUS FOR PROCESSING INTERRUPTS                IN MICROPROCESSING SYSTEM                ABSTRACT OF THE DISCLOSURE         Circuitry external of a microprocessor determines priority between different peripheral devices requesting interrupts to generate a restart vector and a signal granting priority to one of the interrupt-requesting devices.  The peripheral device loads its status and address into two addressable registers connected to a common system bus.  The restart vector is loaded into the instruction register of the microprocessor.  The microprocessor treats the restart vector as an instruction to store the contents of the program counter in memory and loads certain bits of the restart vector into the program counter.  These bits repre-sent the starting address of a subroutine of eight instructions for analyzing the interrupt.  An interrupt is recognized and the status and identification of the interrupting device is stored in a single instruction cycle.  On the next instruction cycle the first instruction of the interrupt analysis routine may begin.  During this analysis routine the contents of the two addressable registers may be read out to determine which device caused the interrupt and what action should be taken in view of the status of the interrupting device.  Provision is made for processing interrupts other than those requested by peripheral devices, and each type of interrupt generates a different restart vectro thus selecting a different address as the first instruction address of the interrupt analysis routine.

Shackle Abstract of the Disclosure A pressure-sensitive carbonless transfer sheet comprising a paper substrate having a front and back surface and a coating composition adhered to at least one of the front and back surfaces of the paper substrate.  The coating composition is set to a flexible, tack-free coat, and the coating composition includes a solvent free non-aqueous hot melt suspending medium which is characterized by being substantially water insoluble, being characterized by being substantially water insoluble, being characterized by the presence of one or more functional groups selected from the group consisting of:  carboxyl, carbonyl, hydroxyl, ester, amide, amine, heterocyclic groups and combinations thereof to impart polarity thereto and having a melting point of from about 60°C. to about 140°C. and a melting point range of lessthan about 15°C.  In addition the coating composition includes an encapsulated, chromogenic material which is substantially dis-persed therein, the hot melt suspending medium being compatible with the color forming characteristics of the capsular chromogenic material.  This invention further includes a liquid chromogenic coating composition which comprises a hot melt suspending medium in combination with a microencapsulated chromogenic material.  The chromogenic material is a color precursor of the electron donating type which is mixed with a carrier oil to form an oil solution of the chromogenic color precursor material which is then com-bined with one or more wall forming compounds.  A novel process is provided for producing a pressure-sensitive carbonless transfer sheet which comprises the steps of preparing a hot melt suspending medium, the hot melt suspen-ding medium being water insoluble and having a melting point of from about 60°C. to about 140°C. and a melting point range of less than about 15°C.  A microencapsulated chromogenic material is prepared and dispersed in the hot melt suspending medium, the chromogenic material being a color precursor of the electron donating type.  A coating dispersion is prepared by combining the hot melt suspending medium with the micro-encapsulated chromogenic color precursor material, the hot melt suspending medium being compatible with the color forming or developing characteristics of the chromogenic material.
