Title: Vibration damper
Inventor: CHELNOKOV I I
IPC: F16F9/40
Filed: 1970-02-04
Abstract: 1294523 Horizontally acting hydraulic dampers LENINGRADSKY INSTITUT INZHENEROV ZHELEZNODOROZHNOGO TRASPORTA IMENI AKADEMIKA V N OBRAZTSOVA and KALININSKY VAGONOSTROITELNY ZAVOD 4 Feb 1970 [7 Feb 1969] 5310/70 Heading F2S.  In a horizontally acting piston-cylinder hydraulic damper, liquid is expelled from the cylinder 1 to a reservoir 6 beneath it on the inward (damping) stroke of the piston 2 via a throttling passage 7 and a chamber 9 which after a few initial strokes is maintained full of liquid. This ensures that on the outward stroke of the piston as liquid is drawn into the working chamber 5 from the reservoir 6 through a valve 11 lying below the liquid level and a passage 8, no air is drawn in through the throttling passage 7. Liquid overflowing from the chamber 9 on the inward stroke of the piston returns to the reservoir 6 via an annular space 17 and a port 20. If the pressure in working chamber 5 rises above a predetermined adjustable level, valve 12 opens and liquid returns to the reservoir via the chamber 9 and the space 17. The passages 7 and 8, the chamber 9 and the valves 11 and 12 are all housed within a removable unit 13.

Filed: 1942-04-24
Abstract: 556,947. Counters. IGRANIC ELECTRIC CO., Ltd., and RAPLEY, H. H. April 24, 1942, No. 5544. [Class 106 (i)] An apparatus for counting articles conveyed in a stream which may be interrupted comprises a counter adapted to be driven by the conveyer, means whereby, in response to the rear of a stream passing a first given point, said counter ceases to operate, and means whereby, in response to the front of a stream passing a second given point, said counter begins to operate, this next count always beginning when the same length of the new stream has passed said second given point. A siream of overlapping newspapers is conveyed past levers 2, 21, Fig. 1. According to the presence or absence of papers, circuit-control lever 21 closes or opens a switch 3 in series with a counting switch. When the stream past clutch-control lever 2 ceases, a bar 9 is pressed downwards but is unable to move until a roller 4, engaging a cam 5 on the rotary part of the counter switch, enters a recess 6, when a bar 13 secured to the bar 9 declutches the drive from the conveyer to the counting switch, counting during the arresting motion being prevented by the open switch 3. When a new stream restores the lever 2 and bars 9, 13, the counting switch always starts rotating from the same angular position and, according to the position of the recess 6, allows a preselected number of papers to pass before counting begins. In the modification shown in Fig. 4, lever 2, 21 are spaced apart to an extent depending on the length of the newspaper.

Filed: 1969-01-31
Abstract: 1,210,623. Thrust reverser. ROLLS-ROYCE Ltd. 31 Jan., 1969, No. 5545/69. Heading B7G. A jet propulsion ducted fan engine 12 has a value, for providing reverse thrust, consisting of two kinds of flaps 24 and 26 arranged circumferentially in the cowl 14. A translatable midportion 28 of cowl 14 is pushed downstream by rams and in doing so exerts a force via links 34 on flaps 24, causing them to fold about hinge 36 and pivot radially inwards, thereby obturating the annular fan duct 18 (Fig. 1); the pressure build up then causes flaps 26 to pivot against the action of springs 48 and about centres 50. Hence the air flows radially past flaps 26 to guide vanes 30 where it is directed to provide a reverse thrust. The flaps 26 are held open by providing an aerofoil shape 52 on one side of each half of flaps 26, so that the air flowing past will exert greater pressure on the flat side of the flap; the pressure differential biasing the flaps towards each other (Fig. 3, not shown).

Title: Fluoropolymer compositions and methods of manufacturing them
IPC: C08F259/08
Filed: 1960-02-22
Abstract: Polymeric materials are made by contacting a fluoropolymer in the form of an aqueous emulsion or a coagulated emulsion with ethylenically unsaturated monomeric material in liquid phase, and polymerizing the monomeric material in the absence of a free-radical producing catalyst to produce a material in which the polymerized monomer is distributed throughout the fluoropolymer. Fluoropolymers used are those consisting of a chain of carbon atoms in which more than half the sites available for bonds other than carbon-carbon bonds are occupied by fluorine atoms and the other sites are occupied by other halogen atoms, hydrogen atoms or more fluorine atoms, e.g. polytetrafluoroethylene, polychlorotrifluorethylene, polytrifluoroethylene, polyperfluoropropylene and a copolymer of vinylidene fluoride and chlorotrifluoroethylene.  Monomers specified are aliphatic and aromatic unsaturated hydrocarbons, unsaturated acids, salts, esters, amides and nitriles, vinyl esters, allyl compounds, unsaturated amines and unsaturated ethers. The polymerization of the monomer is preferably effected by means of ionizing radiation, ultraviolet light or heat.  The examples describe the following processes: (1) a mixture of styrene and a polytetrafluorethylene emulsion is subjected to high speed stirring and the resulting coagulum is irradiated from a cobalt-60 source; (2) a mixture of 4-vinylpyridine and a polytetrafluoroethylene emulsion is subjected to high speed stirring, the resulting coagulum is formed into sheets and exposed to ultra-violet light; (3) styrene is blended with an emulsion of a vinylidene fluoride-chlorotrifluoroethylene copolymer and the mixture is irradiated from a cobalt-60 source; and (4) a mixture of styrene and an emulsion of polytetrafluoroethylene is irradiated from a cobalt-60 source.  Reference has been directed by the Comptroller to Specification 820,120.
