Title: Apparatus and method for dispensing detergent in a warewash machine
Inventor: REINHARD ROGER A
IPC: A47L15/44
Filed: 1991-01-15
Granted: 2001-07-03
Abstract: A dispensing apparatus and method for dispensing detergent in a warewash machine. The rinse water spray system or an alternate water source is monitored to determine if water is being supplied to the warewash machine. Once water is sensed being supplied to the machine, the apparatus determines whether the water is being supplied for a rinse cycle or a fill cycle. The amount of detergent dispensed is controlled based upon the determination of whether the water is being supplied in a rinse cycle or a fill cycle. If the apparatus determines that the water is being supplied for a rinse cycle, a make-up amount of detergent is dispensed upon completion of the rinse cycle. If the apparatus determines that the water is being supplied for a fill cycle, the washtank is pre-charged with the desired concentration of detergent during the fill cycle.

Title: External memory system having programmable graphics processor for use in a video game system or the like
Inventor: SAN JEREMY E
IPC: A63F13/08
Filed: 1992-07-23
Granted: 2002-09-10
Abstract: A fully programmable, graphics microprocessor is disclosed which is designed to be embodied in a removable external memory unit for connection with a host information processing system.  In an exemplary embodiment, a video game system is described including a host video game system and a pluggable video game cartridge housing the graphics microprocessor.  The game cartridge also includes a read-only program memory (ROM) and a random-access memory (RAM).  The graphics coprocessor operates in conjunction with a three bus architecture embodied on the game cartridge.  The graphics processor using this bus architecture may execute programs from either the program ROM, external RAM or its own internal cache RAM.  The fully user programmable graphics coprocessor has an instruction set which is designed to efficiently implement arithmetic operations associated with 3-D graphics and, for example, includes special instructions executed by dedicated hardware for plotting individual pixels in the host video game system's character mapped display which, from the programmer's point of view, creates a "virtual" bit map by permitting the addressing of individual pixels -- even though the host system is character based.  The graphics coprocessor interacts with the host coprocessor such that the graphics coprocessor's 16 general registers are accessible to the host processor at all times.

Title: Method for preparing asymmetric radial polymers
Inventor: TSIANG RAYMOND CHIEN-CHAO
IPC: C08G81/02
Filed: 1992-10-26
Granted: 2002-07-16
Abstract: METHOD FOR PREPARING ASYMMETRIC RADIAL POLYMERS        A method for preparing asymmetric radial polymers wherein the different polymeric arms are contacted sequentially with a non-polymerizable coupling agent. Contacting of the final step in the process, which frequently but not necessarily always will be the second step in the process, will be carried out in the presence of a polar compound suitable for increasing the amount of vinyl content in a conjugated diolefin polymer during polymerization thereof. The method used narrows the relative arm distribution of the several asymmetric radial polymers produced and significantly increases the amount of total product having the desired ratio of polymeric arms and accomplishes this objective in relatively short reaction time. Any non-polymerizable coupling agent known in the prior art to be useful in the production of asymmetric radial polymers may be used in the method of this invention but non-polymerizable coupling agents having from 3 to about 12 functional groups are most effective and non-polymerizable coupling agents having 2 or 3 functional groups are most preferred. Useful polar compounds are, generally, selected from the group consisting of ethers, tertiary amines, pyridine and pyrolidene compounds.
