Abstract: A mechanical hand tool converts random-sized boards or planks into small, uniformly sized pieces suitable for use as kindling wood for stoves, fireplaces, and campfires. The device as a whole works on the principle of pincers or nippers, comprising two handles connected by means of a series of pivots and levers to jaws carrying opposing splitter blades. The mechanical advantage of the tool is increased significantly by the compounding action of the multiple pivots such that the physical effort involved in applying the tool is minimized. The tool is applied by holding the work, consisting of any of a broad range of predetermined sizes, edge-up between the feet of a user, who stands erect and astride the board or plank as it lies on the floor or ground.

Abstract: A circuit chip mounting arrangement for use in a multiple chip unit (MCU) of a computer is disclosed which provides high chip packing density to decrease signal path lengths and thereby increase operational frequency. Chip mounting assemblies are employed which include a centrally located metal heat sink block attached to a chip site on the MCU base. A plurality of circuit chips are attached by their top sides to the front and back sides of the heat sink block with a thermally conductive electrically insulating adhesive. The chips are electrically connected to vertically disposed interconnect boards on either side of the heat sink block, and corresponding flex circuits are employed to connect the interconnect boards to bonding pads on the chip site. A pair of the chip assemblies can be disposed on a single chip site of the MCU, and any desired number of circuit chips can be disposed in each chip assembly.

Abstract: A tilt base assembly includes a base and pairs of elongated feet which attach to the bottom of a cathode ray tube (CRT) display terminal unit. The base includes a pair of trapezoidal shaped base members which attach to the ends of a horizontal plate. The elongated feet suspended from the bottom of the terminal unit rest on both inclined surfaces of each of the trapezoidal shaped base members. The front inclined surfaces of the trapezoidal shaped base members are constructed to include a plurality of indentations which provide a corresponding number of stationary positions for providing different operator viewing angles over a wide range of adjustment. Both front and rear inclined surfaces of the trapezoidal base members are provided with side walls so as to confine the terminal feet movement to the track-like areas within the side walls.

Abstract: An electronic computer includes a plurality of printed circuit boards that are slideably mounted in spaced parallel planes within a housing. The housing contains an input/output bus arrangement which is substantially open in the middle. A power supply is detachably mounted to the housing in such a manner as to automatically connect to the input/output bus arrangement when it is secured in place. The power supply includes suction fans which draw ambient air in through the front of the housing over the printed circuit boards, through the open portion of the bus arrangement and hence over critical portions of the power supply. The air is initially drawn through perforated openings in a hinged control panel in one preferred embodiment. In another preferred embodiment, the air is drawn through a stationary member at the front of the housing.
