Abstract: A framed garment bag with flexible walls having exterior suspension means at the top thereof and a jointed clamp disposed in a substantially vertical plane on the interior thereof. The upper jaw of the clamp which is fixed to the underside of the top and the lower jaw which is pivoted to the rear end of the former are fitted with contiguous edges of yieldable material which effect a tight retention of the hooks of the garment hangers disposed therebetween when the jaws are clamped together in a plane parallel to the top of the frame of the bag. When the jointed clamp is open for loading or unloading the garment hangers, the controlled limited downward inclination of the lower jaw provides a convenient frictional guide for the hangers preparatory to their lifting into juxtaposition to the fixed upper jaw by the movement of a clasp of high mechanical efficiency, which movement terminates in a secure clamping between the jaws.

Abstract: A cigarette package comprises a body 20. The body includes a plurality of bores 26 which are divided by a membrane 32 into a cigarette containing chamber 34 and a cigarette butt receiving chamber 36. Each chamber 34 contains an unsmoked cigarette 6. When a butt 10 is pushed into a butt receiving chamber 36, it engages and pushes an unsmoked cigarette 6 up past the top surface 28 of body 20 to allow that cigarette to be manually removed. This discourages littering of cigarette butts 10. Alternatively, body 20 can be formed so that each cigarette 6 is movable without having to store cigarette butt 10 in one of the chambers 36.

A plurality of video fields are recorded in each video track extending across the video tape such that the burst of noise produced when the magnetic head crosses over the guard band between separate video tracks during the slow or fast mode of operation of the video recorder is encountered in only one of the field regions in the video track. This burst of noise is utilized to control the television monitor circuit so that the video field region which is free of noise is reproduced on the monitor while the video field region which contains the noise is blanked out from the monitor. As the noise progresses from one field region to the succeeding field region in the video track, means is provided for automatically switching to display of the noise-free field region.

Abstract: A liquid dispenser, adapted to rest upon the bottom of a flush tank, includes a container having a quantity of the concentrated soluble material therein, and a closure forming a piston extending into the top opening of the container. The closure forms a liquid flow passage between the interior and exterior of the container and is adapted for shifting in response to the flush/fill modes of the tank cycle. The closure rises to its upper limit by flotation from entrapped air within the closure, retains liquid in an open cavity thereof and becomes fully submerged by the rising level of the tank liquid. As the closure rises, tank liquid enters the container through the flow passage for mixing with the chemical concentrate. During the flush mode of the tank, the closure falls by gravity and is augmented by the retained water in its cavity as the receding level of the tank liquid passes below the upper rim of the closure.

Abstract: A method of flushing a toilet for aircraft or the line using vacuum and pressure, in which there is a toilet or other waste receiving bowl, a waste the holding tank, and a valve means for opening or closing the drain line. A vacuum is created in the waste holding tank and the drain line. The drain line is closed or opened by the action of the valve means. In the method the valve means is actuated by vacuum to open the drain line to connect the bowl to the holding tank to apply vacuum on the bowl to suck the contents from the bowl and deliver it to the holding tank. When the bowl has been emptied, pressure is applied to the valve means for closing the drain line to again build up vacuum in the system for subsequent operation.

Abstract: A flush valve mounting permitting adjustment of water flow to the requirements of different types of toilet bowl comprises a housing in which a float container with a float therein is removably emplaced. The lower portion of the housing has window apertures through which water can flow from the flush tank into a drain upon lifting of the pipe which carries the valve plate. A wall extending downwardly from the floor of the float container abuts the interior of the window openings, and this wall itself has through-flow apertures separated by webs formed by the wall. The openings in the window apertures are diminished by rotating the float container relative to the housing. This permits the water flow to be adjusted to the requirements of the particular toilet bowl.

Abstract: A collapsible bathing assembly utilizes a flexible liner housed within a cabinet.
