Title: Fastener driving tool with sound deadening features
IPC: B25C1/04
Filed: 1973-07-10
Abstract: 1377344 Fastener driving tools J M WILSON (Spotnails Inc) 10 July 1973 32748/73 Heading B4C Sound-deadening in a fastener driving tool is effected by mounting a section 33 of sound deadening material on the piston 18 and another section 34 on the valve 25 for engagement with one another when the piston is retracted and the valve closed as shown in Fig. 1. Instead of a coating 33, the material on the piston may be a pad 23, Fig. 4, adhesively secured in a recess 22 the material being moulded of polyurethane with or without additives of asbestos and fluorine-containing polymers. Sound-deadening material may also be applied at 35 on the piston for engagement with a bumber 24 and at 36 on the cover 13 for engagement by the valve when the valve is lifted to allow air to pass into the cylinder above the piston and seal off the exhaust port 28 by the engagement of a tubular part 25a with a seal 32. Automatic recycling occurs when the trigger is continuously depressed and the tool is positioned against a workpiece.

Abstract: 465,867. Optical sound-recording apparatus and processes. ELECTRICAL RESEARCH PRODUCTS, Inc. Dec. 1, 1936, No. 32908. Convention date, Dec. 4, 1935. [Class 40 (ii)] In order to minimize " ground noise," a sound film, Fig. 4, is provided with a central opaque trace 28 of constant width and side traces 27, whose inner edges 30, 31, extend approximately parallel to and are located closely adjacent the envelopes of the amplitude variations of the central trace. In the production of the negative film, a light valve of the kind described in Specification 382,663 is utilized except that the valve has three vertical ribbons 5, 6, 7, Fig. 1, instead of two which vibrate across a narrow slit 20 in the casing 19, the central ribbon 5 being fed with amplified modulated current, and the outer ones with amplified rectified current in opposition to a constant biasing current furnished by a battery 8. In the absence of sound, the bias current causes the outer ribbons to approach closely the central ribbon, in order to reduce the width of the exposed portion of the film to a minimum.

Title: Diffusion purification of gases
IPC: C01B3/50
Filed: 1963-08-23
Abstract: A selected gas is separated from a mixture by contacting the mixture at superatmospheric pressure with one side of a thin unsupported non-porous diffusion membrane selectively permeable to the gas, passing a sweep gas at superatmospheric pressure into contact with the other side of the membrane and maintaining the partial of the selected gas in the sweep gas below the partial pressure thereof in the mixture.  The membrane may be 0.1 to 5 mil thick and may be subjected to a pressure differential of up to 100 psi which may be controlled by a Bowdon tube, diaphragm or bellows to control the gas velocities on either side of the membrane.  The sweep gas which may flow con-current or counter-current to the mixture, may be steam or hydrogen.  The membrane is preferably Pd-Ag, Pd-Ru, Pd-Au, or Pd-B but Fe, Ni, Cu, Pt and Mo may also be used for hydrogen diffusion.  A silver foil may be used for oxygen diffusion.  A gas system for separation of H2 with N2 as a sweep gas at 200 DEG  to 800 DEG C. by diffusion through Pd or an alloy thereof is described in relation to a Figure.  A multiple membrane diffusion cell is also described in relation to another Figure, the cell being constructed of stainless steel and silver.
