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.

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.

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.
