Abstract: A pedal-operated valve is provided controls the rate of fluid flow in a soft hose. A cradle positions a section of the hose so that its cross-sectional area can be compressed by the hinged rotation of a pinchcock toward the cradle in response to a pedal force to reduce the rate of flow. The compressed cross-section expands in response to the internal fluid pressure of the hose upon release of the pedal force to increase the rate of flow. A latch secures the pinchcock in an angular orientation relative to the cradle to maintain the reduced cross-sectional area. A lever is pedal operated to disengage the pinchcock from the latch.

Abstract: An electronic package is disclosed in which a plurality of stacked "same function" IC chips are designed to be used in lieu of a single IC chip, and to fit into a host computer system, in such a way that the system is "unaware" that substitution has been made. Memory packages are of primary interest, but other packages are also feasible, such as packages of FPGA chips. In order to "translate" signals between the host system and the stacked IC chips, it is necessary to include suitable interface circuitry between the host system and the stacked chips. Specific examples are disclosed of a 4 MEG SRAM package containing 4 stacked IC chips each supplying a 1 MEG memory, and of 64 MEG DRAM packages containing 4 stacked IC chips each supplying a 16 MEG memory. The interface circuitry can be provided by a single special purpose IC chip included in the stack, referred to as a VIC chip, which chip provides both buffering and decoding circuitry. Additionally, the VIC chip should provide power supply buffering.
