Abstract: ABSTRACT OF THE DISCLOSURE           A dishwashing apparatus having a dispenser operable at a preselected time in the dishwashing cycle for dis-pensing a treating liquid such as a rinse additive.  The dispenser is arranged so as to measure in a measuring cup a preselected quantity of additives as an incident of moving the dishwasher door between opened and closed positions and to dispense the preselected quantity at the proper time in the wash cycle.  The measuring cup for the additive is pivotally mounted within the dispenser and is pivoted from a position submerged in the liquid additive when the dishwasher door is opened in the horizontal plane, and above the liquid additive level when the dishwasher door is closed in the vertical plane, to a position so as to discharge the liquid by gravity into a discharge conduit. The discharge conduit additive receiving opening is located above the level of the liquid additive at all door positions and conveys the liquid additive by gravity into the washing chamber.  The pivoting of the measuring cup is effected at the desired preselected time in the dishwashing cycle.

Abstract: INTERNAL COMBUSTION ENGINE WITH   STEPPED PISTON SUPERCHARGER     ABSTRACT OF THE DISCLOSURE        A reciprocating piston four cycle internal combustion engine utilizes a stepped piston the stepped portion of which, working in an enlarged bore in the block, serves as a compressor to provide a supercharged fuel-air mixture to the combustion chamber.  The compressor delivers two compression strokes per engine cycle.  The compressed fuel-air mixture travels from the compressor via a bypass manifold, which also serves as an accumu-lator, to the main cylinder via an intake valve.  Fuel-air mix-ture is admitted to the compressor cylinder through the crankcase and valved passages through the stepped portion of the piston.

Abstract: ABSTRACT:           A pulse generator fox generating pulse groups with desired widths and relations (spacings) within and between the groups up to extremely high speeds and with a time accuracy of the order of nanoseconds e.g. in radar applications.  It is purely digital and operates on a control frequency which may he derived from an internal crystal oscillator ox may be externally supplied.  The generator is divided into two main units, a first unit for determining the spacing of the pulse groups, and a second unit controlled by the first unit for determining the pulse widths and controlling pulse generator means. Different time space numbers and pulse widths numbers may be programmed into PROM memories of said units and may be selected by the same set of operating mode signals.  The time spacing may also be optimized by means of an exter-nal computer controlling a further PROM holding informa-tion which may be combined with the time distance PROM information.  Staggering and jittering radar modes may be obtained by supplying relevant mode signals.  The pulse groups may comprise a ("listening interval") control pulse having a time position which falls within the next following pulse group but is generated with a fixed rel-ation to the pulses of its own group.  Further trimming possibilities with respect to the internal pulse relations of a group are available.  All mode signals required are of the two-level type.

Abstract: ABSTRACT OF THE DISCLOSURE     A selective memory addressing scheme employs a programmable read only memory (PROM) which responds to the opcode of the next instruction to be executed and supplies control information to memory module selection registers.          The memory module selection registers operate in conjunction with the internal address registers to provide the necessary steering information for properly addressing the intended memory location. The PROM is programmed in accordance with the instruction set by which the processor operates and is coupled to decode the opcode contents of the instruction register that has been loaded, in a lookahead fashion, with the instruction following the instruction presently being executed by the central processing unit.         The PROM has a first output that defines whether or not a second output of the PROM is to be used to select the memory module containing the operand to be references inthe execution of the next instruction. This second output of the PROM is of a code size required to identify any one of the modules is the bank. The PROM has a third output that may be used to increment the location counter based upon the length of the next instruction. Where the second output of the PROM is not to be used to select the memory module containing the operand to be referenced, the first output of the PROM has a state such that it gates out information stored in a program status word register to identify the memory module containing the operand of the next instruction to be executed.         To provide for direct CPU intervention in the execution of instructions, such as may occur in the case of an interrupt, prescribed bits of the CPU data bus may be selectively coupled to the module selection circuitry, so that the opcode-dependent operation of the PROM is bypassed and direct CPU selection within the memory bank may be achieved.
