Abstract: A door jamb assembly for varied installations in a conventional rough cut door opening disposed in a wall, the assembly including first, second, and third elongated members for mounting on the sides and top of the rough cut door opening to form a pair of door jambs and a header. Two of the elongated members are configured so that they will mate on one end thereof to the first elongated member and on the other end thereof to a portion of the other elongated member between the ends thereof, these two elongated members being essentially mirror images of each other. As a result, a door jamb assembly is provided which can be installed in various width door openings to provide jambs for doors which can be hung with left or right hinges and which open in or out. Additionally, the width of the jambs and header is variable to accommodate walls of different thicknesses.

Abstract: In an automatic pick-up sewing system for curved edges of a fabric piece such as an outer pocket on clothing such as a jacket, the clothing kept in a horizontal state with the fabric piece pressed against a sewing needle is displaced two dimensionally during pick-up sewing as programmed under computer control while the sewing needle is driven for concurrent horizontal rotation so that the point of the sewing needle should always be directed in tangential directions of a sewing line on the fabric piece. Beautiful pick-up sewing is achieved quite at high efficiency without any need for highly skilled manual operation.

Abstract: An acupressure apparatus for applying vibrational pressure evenly to a plurality of preselected points on a shaded portion of a living body such as upon the face thereof includes a housing and a flexible membrane secured to the housing to form an enclosed chamber between the housing and the flexible membrane for containing therein a liquid. A plurality of protrusions are carried on the flexible membrane and, when the housing is placed adjacent to the shaped portion of the living body, the plurality of protrusions contact preselected acupuncture points. The fluid is excited by vibrational energy such that this energy is transferred to the plurality of protrusions evenly so that the protrusions exert vibrational pressure on the preselected acupressure points. The fluid can be heated if desired.

Abstract: A bottom closure for resonator of a sound bar on percussive musical instruments has a radially expandable construction for uniform pressure contact of a gasket with the resonator inner wall. Ideal follow-up of the bottom closure to the current shape of the resonator bottom end resulted from its elastic deformation assures almost perfect air leak prevention under any conditions.

Abstract: A propelling and braking apparatus for a zero pressure accumulator conveyor includes a driven belt normally in intimate contact with a plurality of supporting rollers and a braking device disposed proximate thereto. Both the driven belt and the braking device apparatus are disposed between and beneath the supporting rollers and are resiliently mounted to a mounting bracket which is adapted to be affixed to one of the side rails of the conveyor. By filling an expansible tube with a pressurized fluid, the driven belt is removed from intimate contact with the supporting rollers and the braking device is caused to come into contact therewith applying braking forces thereto, thereby preventing contact between articles moving along a conveyor.

Abstract: A non-destructive method and apparatus for inspecting materials in excess of 500.degree. C. includes a dual transducer disposed upon a delay line suitable for operation at the elevated temperatures. The delay line is divided into two parts acoustically isolated and is cooled by a fluid to maintain the surface upon which the transducers are mounted at a safe operating temperature.

Abstract: A fluid proportioning system for apportioning fuel usage among several discrete fluid fuel supplies which are used to supply fluid fuel to a single commonly used apparatus. An application for the invention is in a multidwelling unit wherein each unit is heated from a common furnace. Each tenant's metered gas line is tapped in proportion to the amount of heat necessary to heat their dwelling unit by the adjustment of precision valves, the gas from each line being combined in a manifold. Means are provided to preclude interaction of the individually metered gas lines when the furnace is not consuming gas.

Abstract: A power supply system for providing uninterruptible DC output power with momentary failure of the primary or AC mains supply utilizing a DC power source for back-up includes a power transformer having two primary windings, rectifying means, a serially-connected high voltage switching device coupling one primary winding to the AC primary mains supply, and a low voltage switching device coupling the second primary winding to the back-up DC supply. An output winding on the power transformer is coupled to a rectifying device for providing a DC output voltage. A transition circuit arrangement senses the DC output voltage and the resulting DC voltage generated by rectifying the AC mains supply and controls the duty cycle of the high voltage and low voltage switching devices by gradually increasing the duty cycle of the low voltage switching device to supply additional power when the AC mains voltage and resulting DC voltage decreases, thereby providing a virtually transient-free DC output voltage.

Abstract: A liquid sampling apparatus for use in sampling the liquid in a well pipe to determine surface contaminants contained therein includes a unitary tubular housing formed to provide a valve seat therein.
