Abstract: In a solenoid driven hammer for an impact printer, the armature, which is driven by the magnetic field provided by the solenoid's coil, is integral with the hammer which strikes a printing element on a print wheel. The shape of the pole piece in the solenoid conforms to the shape of the leading surface of the armature to provide a magnetic force field that is of constant strength as the armature is propelled toward the pole piece when the solenoid coil is energized. The hammer, being unitary with the armature, is thereby propelled against the printing element. As the hammer rebounds after striking the printing element, the armature strikes a polyurethane cushion which absorbs substantially all of the energy of the armature/hammer unit, thereby bringing the unit to a complete stop so that the next stroke may be quickly commenced.

Abstract: A gas discharge lamp is connected across an inductor and in series with a solid state switching device and a resistor, and this combination is connected across a voltage source. This switching device is controlled by a monostable multivibrator, the input of which is connected to the output of a comparator amplifier sensing the difference between the voltage drop across the above-mentioned resistor and a reference voltage which may be changed to vary light intensity. A supply voltage feedback control loop uses a power oscillator to maintain the voltage supplied to the inductor and the lamp at a level corresponding to a symmetrical voltage wave form in the lamp in order to maximize lamp efficiency. A reference voltage feedback control loop controls the reference voltage supplied to the comparator amplifier in order to minimize the effect of power line variations on lamp intensity while allowing controlled variations in intensity by the user.

Abstract: The multi-layered back plane of this invention permits a plurality of processors and a plurality of memories to be interleaved through separate memory interface boards in a computer in a manner which provides a significant reduction of path length while eliminating crossover of signal cables and permitting the use of identical memory interface boards, resulting in a significant increase in the clock rate and efficiency of the computer.

Abstract: A panel file, for the storage of flat, flexible data elements, consists of plural, vertically spaced pockets, the entrances of which are formed by a plurality of vertically spaced, horizontally extending strips of resilient material. The strips are arranged so as to have an upper edge which overlaps the lower portion of the next upwardly adjacent strip. The strips are fastened together at their lateral margins. The lower portions of the pockets are formed by a support sheet which is attached to the panel on the surface opposite the pocket entrances. The support sheet is cut so as to have a column of inverted "V"-shaped straps, each having a vertex which is attached to the back of strips above overlapped portions thereof. The strips have an upwardly indented bottom edge with a central vertex at the point where the support sheet strap is attached to the next downwardly adjacent strip.

Abstract: A gas discharge lamp is connected in parallel with an inductor and in series with a solid state switching device and a resistor, and this combination is connected across a rectified AC voltage source. This switching device is controlled by a monostable multivibrator, the input of which is connected to the output of a comparator amplifier sensing the difference between the voltage drop across the above-mentioned resistor and a voltage which bears a predetermined relationship to the rectified AC signal of said source. This results in a high frequency operation of the lamp wherein the lamp current level is controlled or modulated in accordance with the rectified AC supply voltage, providing a high power factor lamp circuit without the normal heavy lamp ballast. In addition, a circuit is disclosed which prohibits the lamp from exhibiting a high resistance when the AC voltage is at a zero crossing point, protecting the solid state switching device and stabilizing the high frequency.

Abstract: A container is disclosed with a valve opening at its bottom wall to permit steam to circulate into the container and to permit any condensation to drain from the container while the valve is open. The valve is closed by an expandable chamber in response to the pressure drop at the end of a sterilizing cycle. A valve controlling the flow of steam into the expandable chamber closes when subjected to the high temperature steam, thus capturing steam within the chamber. This steam expands when the pressure drops to close the valve in the container. The container lid and gasket permit steam to be withdrawn from the container but prevent air flow into the container. A vacuum created in the container at the end of the sterilizing cycle holds the container lid in place and holds the valve closed.Also disclosed is a bimetallic spring valve which opens when steam is applied to a container and closes when the temperature drops as steaming ceases.

Abstract: A batting tee comprising a planar base adapted to rest on the ground, the base having a plurality of holes therein and being a representation of a baseball home plate, an elongate, length-adjustable, telescopic member, such member including an elongate pipe being externally threaded at one end thereof, such one end of the pipe being extendable through any one of the holes in the base, and a disc having an internally threaded central hole for receipt of the one end of the pipe for removably connecting the telescopic member to any one of the holes in the base, the member supporting a ball above the selected hole in the base.

Abstract: An energy efficient process is disclosed for the continuous production of semiconductor matrices formed from depositing doped silicon or germanium films on metallic sheet substrates. The energy released from such deposition can then be used to regenerate the anode material used in the deposition.

Abstract: A refuse collection device includes a pair of side-mounted lift arms with a carriage for engaging a refuse container. The carriage is laterally extendable to reach out and engage the container. The lift arms swing upward to dump the refuse from the container into a hopper. An auger in the hopper bottom precompacts the refuse and displaces it into a refuse body behind the hopper. The operation of the lift device is reversed to return the container to its original position.

Abstract: A chemical heat pump system is disclosed for use in heating and cooling structures such as residences or commercial buildings. The system is particularly adapted to utilizing solar energy, but also increases the efficiency of other forms of thermal energy when solar energy is not available. When solar energy is not available for relatively short periods of time, the heat storage capacity of the chemical heat pump is utilized to heat the structure as during nighttime hours. The design also permits home heating from solar energy when the sun is shining. The entire system may be conveniently rooftop located. In order to facilitate installation on existing structures, the absorber and vaporizer portions of the system may each be designed as flat, thin wall, thin pan vessels which materially increase the surface area available for heat transfer.

Abstract: A flexible tube container has a plurality of cells linearly disposed along the length of the tube. The cells are defined by a plurality of segmented weld lines, each segmented weld line extending the width of the tube. Each segmented weld line permits fluid communication between the various cells in the container and the formation of individual frozen confections within each of the cells upon freezing of the fluid therein. Dispensing of an individual frozen confection is easily done by bending the tube along any segmented weld line, which detaches an adjacent cell containing an individual frozen confection and immediately permits sanitary consumption of the frozen confection while it is hygienically protected within the detached cell.
