  • Patent number: 4423848
    Abstract: An improved helicopter seat primarily for combat aircraft includes at least upper, intermediate, and lower pairs of energy absorbers attached between the seat bucket and the frame of the helicopter and operable in both tension and compression. An upper pair and lower pair of steel tension rods attached between the frame and the seat bucket provide attentuation in a lateral direction. The energy absorbers comprise a plurality of telescoped tubes interfitted into one another and having coils of wire frictionally engaged between adjoining tubes such that energy is dissipated by motion of the tubes relative to one another through the plastic deformation of the coils of wire. The energy absorbers are adjusted to optimize the safety parameters of occupants of the seat under a range of potential crash conditions including the most probable crash condition, and for occupants having a substantial range of weight.

  • Patent number: 4252257
    Abstract: An automatic closure for collapsible tubes, squeeze bottles, and the like containers of the type formed from resilient plastic material. The container typically is tubelike, provided with a tapered or frusto-conical neck portion terminating in a flattened mouth defining end lips forming an openable closure. Pressure applied to the body of the container remote from the lips to forms a transverse pinch-off across the end portions wherein the lips are deflected or bent along a line of curvature to one side or the other and at an angle to the axis of the container, and wherein the lips are also bowed, having a curved contour. Such pinch-off forms a closure across the neck portion. The pinch-off opens in response to pressure on the walls of the container proximate thereto in a manner to relive the pinch-off and permit the fluid contents to flow. Specifically, the pinch-off is in the following form: the end lips of the neck have a bowed contour about the lengthwise dimension.

  • Patent number: 4174743
    Abstract: An integrated apparatus or device for transferring, that is, pumping water from a water bottle to a water fountain having a reservoir with a dispensing faucet. A housing is provided carrying a stopper for insertion into the neck of a water bottle. Within the housing, there is a pump; a tube is connected to the pump discharge and extends through the stopper for pumping air into the bottle. A further tube passes through the stopper for transferring water from the bottle. The other end of this tube extends to fitting means which can be placed on the reservoir in a position normally occupied by the water bottle in an inverted position. This fitting carries a float valve which closes the end of the supply tube when the reservoir is filled.

  • Patent number: 4097894
    Abstract: A secured scramble decoder filter comprised of a narrow band filter assembled on a fragile substrate and mounted in a housing wich automatically destroys the filter when any tampering is attempted. The filter is a series tuned network bridging a conductor coupled through a capacitor to a parallel tuned network, which is connected to ground. The coils for the filter are printed on a special electronic glass tube for temperature stability while the capacitors are deposited on the fragile substrate. The filter is mounted in a sealed housing in brackets with a spring, loaded to break the substrate when the device is tampered with to render it inoperative. The device is provided with a mounting screw requiring a special tool for removal so that when the device is mounted any prying in an attempt to remove the device will trigger the destruction of the filter.

  • Patent number: 4084695
    Abstract: A clear plastic pillbox having an intermediate longitudinal channel and lateral partitions which form a multiplicity of compartments therein for storage and convenient dispensing of medicament tablets. The pillbox is sealed by a clear plastic cover having a plurality of slots through its surface which form peripheral seals around the projections of the lateral partitions above the sidewalls of the pillbox and thus individual sealing tabs are provided for each of the compartments created by the longitudinal channel and lateral partitions. The individual sealing tabs are frangible and may be broken away to provide access to particular compartments, which may be pre-loaded by pharmacists with medicament tablets or doses of medication for scheduled use.

  • Patent number: 4074311
    Abstract: A system for subscription TV security which is comprised of a scramble signal generator which adds a modulated RF carrier signal to the TV channel transmission. Preferably the frequency of the scramble signal generator is selected to fall within the band of frequencies of the TV channel between the video carrier and the audio carrier. The TV channel is transmitted to receivers encoded with the scramble signal carrier providing false and misleading information, preventing the receiver from reconstituting a coherent picture or sound while this scramble signal is present. The transmitted signal is decoded, (i.e. scramble signal removed), restoring regular reception by filtering with a sharply tuned high-Q notch filter attached to the drop line going to a TV receiver. By careful selection of the band width and attenuation of the filter and pre-emphasis of the channel band, degradation of the video information is prevented.

  • Patent number: 4071065
    Abstract: A one-piece container formed as an injection molding preferably from polypropylene. The single piece is molded in preformed sections joined by thinner portions or parts of material which serve as hinges, the sections being relatively moveable about these parts. The sections are preformed to constitute portions of a container along with a closure for the container so that when the sections are moved about joint parts a complete container with a closure cover is formed. Preferably the container has inwardly extending flexible members formed on at least one section to engage an article within the container to retain it in position. The container is particularly adapted for use with calculators.

  • Patent number: 4067424
    Abstract: A readily removable tool holder constructed to be held in a receptacle which may be carried on the spindle of a tapping attachment. A torque release clutch is built into the removable tool holder for the purpose that when one tool holder is substituted for another, it is not necessary to make adjustments in the torque release clutch of the tapping attachment itself. The parts of the torque release clutch are of relatively small diameter to fit into the tool holder. Improvements are embodied in the torque release clutch. Clutch members are provided including a first clutch member and a second clutch member. The main biasing spring acts on the first clutch member. When the clutch parts are disengaged, the first member is moved against the spring and held in an inactive position wherein it is completely out of engagement with the teeth of the other clutch member to eliminate wear.
