Title: Improvements in and relating to rotary machines
IPC: F01C20/14
Filed: 1935-07-02
Abstract: 437,939. Rotary engines. BEUDELS, J., 87, ChaussÚe de Charleroi, Gilly, Belgium. July 2, 1935, No. 18927. Convention date, July 2, 1934. [Class 110 (ii)] The engine is driven by expanding fluid, and comprises vanes 7 mounted on ball bearings 10 supported by a central, fixed, shaft 11, and an eccentric rotor 5 driven by the vanes and containing packing members 12 to allow the vanes a sliding- rocking movement. The inlet and exhaust ports each comprise a number of holes 21<a>, 22<a>, arranged as shown and also helically along the lengths of the cylinders A, B. The last line of holes H lie along a generator of a cylinder. Fig. 3 shows the means of operating the valves by a cam 44 and rollers 47, 48, placed in arms 45, 46, pivoted at 45<a>, 46<a>. All the holes covered by the valve 43 are opened before the valve 42 commences to move. Working fluid enters by one of passages 21, 22, controlled by the position of a piston valve 25, the second passage leading to the atmosphere or a condenser. An additional exhaust 23 or 27 is provided depending upon the direction of motion of the rotor. Pipes 36 ... 39 lead from the spaces 21, 22, to the ends of cylinders 34, 35, and the pressure of the working fluid, or the exhaust, acting through these pipes causes one piston, 32 or 33, to be up and the other down, and so close one exhaust 29 or 31 and open the other. The valve 25 may occupy a central position allowing both passages 21, 22, to be open to exhaust. Fig. 5 shows a means for moving the rod 40 by means of a lever 52 pivotally mounted in a stirrup 53, which is supported on bearings 54. Before the cam 44 can be rotated the rod 40 must be actuated, until the lever 52 reaches one of the slots 55a, 55b at right angles to the slot 55d. The vane tips carry packing bars supported on tension springs to prevent frictional force due to centrifugal action, from becoming excessive. Further packing bars are supported in the vane ends. The rotor is packed by fixed rings 13, 15, on the casing and rotor respectively, and a rubbing ring 14 connected by a spring 16 to the ring 13. The rotor is mounted on a shaft 17 in bearings 19 and provided with gears 20 for transmitting the driving torque to external machinery, which may be mining winch gears.

Abstract: 882,426. Photo-electric control of photographic printing. LOGETRONICS Inc. June 13, 1958 [June 17, 1957], No. 18998/58. Class 40(3). [Also in Group XX] The contrast of a negative print 30 on to which a negative 26 is imaged point by point by a flying spot produced on the end of a cathode ray tube 24 is increased with respect to that of the negative by means of a photomultiplier 34 receiving light which has passed through both the negative and print and the output of which is amplified at 38 to provide a positive feed-back signal which brightens the flying spot on light portions and dims it on dark ones. In a further arrangement (Fig. 2) the negative is adjacent the end of the cathode ray tube and the image is projected on to the print, the photo-multiplier receiving light reflected from the print surface. The specification states that the feed-back signal may change the contrast by controlling spot size or speed.

Title: Method of reducing the coefficient of friction of elastomer surfaces
IPC: C08J7/18
Filed: 1965-01-13
Abstract: A method of reducing the coefficient of friction at surfaces of cured elastomeric products comprises the steps of contacting the surfaces to be treated with at least one compound containing a carboxylic acid group and capable of addition polymerization, initiating a free-radical reaction on the contacted surfaces so as to cause chemical combination and/or physical integration of the compounds and the elastomeric surface and to cause polymerization of the compounds to occur, and subjecting the contacted surfaces to a fluorinating agent.  In one embodiment, the elastomer is (a) contacted with the monomer and exposed to ionizing radiation or (b) contacted with the monomer containing a thermal initiator and heated, prior to contacting the elastomer with SF4, a mixture of NaF and SCl2, or another fluorinating agent. In a second embodiment, the elastomer is contacted with the monomer in the presence of a fluorinating agent and heated under pressure, in which case the said agent initiates polymerization. Acrylic acid is employed as monomer in all the examples, in which slabs of elastomer are washed with soap and water and rinsed with acetone prior to being soaked in monomer, exposed to U.V. light and then heated with SF4 (Examples 1 to 4), soaked in monomer containing benzoyl peroxide, heated and then further heated with SF4 (Example 5), soaked in monomer, exposed to U.V. and then heated with SF4-BF3 complex (Example 6), or exposed to a fluorinating atmosphere generated by the monomer and SF4 complex (Examples 7 to 10), SF4 and BF3-SF4 complex (Example 11) or SCl2 and NaF (Example 12).  The elastomers employed are acrylonitrile rubber (Examples 1, 5 to 7 and 11), neoprene (Examples 2, 9 and 11), natural rubber (Examples 3, 8 and 12) and SBR rubber (Examples 4, 10 and 12).
