Abstract: 212,616. Thompson, W. P., (Union Special Machine Co.). Dec. 8, 1922. Sewing-machine needles, vibrating laterally; chain-stitching; loop-stitching. - In a sewing- machine in which the needle and the looper vibrate laterally in unison to form zig-zag stitching the lateral vibrations for both parts are divided from one member which can be connected to a constantly oscillating lever or be locked against movement. The needle-bar 2 is reciprocated by a needle-lever 4 from an eccentric 7 on the main shaft 8. The pivotally-mounted needle-bar gate 3 is vibrated laterally from a rock-shaft 13 on which is mounted an arm 14 connected to the usual arms 15 constantly-oscillating through variable amplitude. The arms 14, 15 are connected by a latch 20, 22 slidingly mounted in the lever 14 which is normally pressed down by a spring to hold the V-shaped under edge in a fixed groove and which can be raised to engage a square edged slot in the lever 15 by means of a treadle-operated table 23 which when raised bears upon a roller 24 on the latch 20, 22. A looper 36 is oscillated by a link-connection with a lever 43 fulcrummed at 49 on a link 50 and actuated by a lever 45 which is pivoted at 46 to the frame and linkconnected to an extension 48 of the needle-lever 4. The looper is given needle-avoiding movements from an eccentric on the main-shaft 8. The link 50, Fig. 6, is pivoted to an arm 51 of a shaft 52. A second arm 55 on the shaft 52 is adjustably connected by a link 58 to an arm of the shaft 13.

Title: Improvements in or relating to photographic roll film cameras
IPC: G03B17/42
Filed: 1954-11-23
Abstract: 753,122. Photographic roll-film cameras. KODAK, Ltd. Nov. 23, 1954 [Nov. 24, 1953], No. 33903/54. Class 98 (1). A photographic roll-film camera of the type in which the film is wound and the shutter is set, simultaneously and film locking means prevents successive film winding movements without an intervening release of the shutter includes a film take-up shaft carrying a ratchet, a shutter with a setting-element connected thereto, means engageable with the ratchet to lock the shaft, means controlled by the setting-element to  release the locking means, and means controlled by the film movement for holding the locking means in the released position. As shown, when the film is wound by rotating the winding shaft 11 it rotates a sprocket-wheel (not shown) fast with a disc 13. An arm 61 is pivoted to disc 13, and is formed with a curved slot 62 engaging a pin 63 on a lever, 64 pivoted on a stud 65. A pin 66 on lever, 64 engages the forked end of a slider 68, and is held terein by a spring (not shown), the other end of which has a slot 70 receiving a pin 54 on the shutter setting ring. When the shutter is in its normal position, the pin 54 is near the left-hand end of slot 70, as shown in dotted lines in Fig. 1, in which position it acts on the tail 51 of a pawl 46 pivoted at 47 to tilt the pawl 46 against spring action out of engagement with a ratchet 27 fast with shaft 11. A second pawl 45 also pivoted at 47 and spring-urged into engagement with ratchet 27 is held disengaged by a lug 49 on 46. Film-windlng can now be effected, rotating disc 13. An inclined edge of notch 14 acts on the nose 17 of lever 15 pivoted at 16, tilting the lever so thatflange 55 at the end thereof blocks re-engagement of ratchet 27 by pawls 45, 46 when, as a result of the continued rotation of disc 13, slider 68 moves to the right, setting the shutter by moving pin 54 to its fullline position in Fig. 1. As. the film wind continues, lever 64 returns under spring action so that the slider returns to its original position, slot 70 sliding on pin 54, until the nose 17 of, lever 15 drops once more into notch 14, allowing the pawls 45, 46 to re-engage ratchet 27. The pawls are.so spaced as to engage the teeth at half-tooth spacing. The film wind is thus locked untilthe shutter has been released. If it is desiredto make a second exposure without winding the film, the shutter may be re-set by moving slider 68 manually by means of an extension 72 thereof which extends through a slot in the camera casing. Pin 63moves in slot 62 during this action. Back rotation. of shaft 11 is normally prevented by a ratchet 26, mounted on shaft 11 next to ratchet 27, which is engaged by a spring-urged pawl 29 pivoted at 30. A-lever 36 also pivoted at 30 has a lug 37a whichengages an arm 37 of the pawl 29 to disengage it from ratchet 26 when lever 36 is rocked, by depressing an extension 41 which extends through a slot in the camera casing, to allow the film to be rewound into a casette.

Title: Thermoplastic copolymers with antistatic properties
IPC: C08F279/04
Filed: 1966-07-28
Abstract: An antistatic moulding composition comprises (A) a graft copolymer formed by grafting a mixture of styrene and acrylonitrile, or their alkyl derivatives, on to a copolymer of a conjugated diene and an ester of an ethylenically unsaturated acid and (C) a polypropylene glycol which has a degree of condensation of 5 to 1000 and may be etherified or esterified. The composition may also include (B) a copolymer of the mixture of grafting monomers incorporated in (A). Specified backbone copolymers are of butadiene and/or isoprene copolymerized with an acrylate, methacrylate or fumarate ester and, in some cases, a small amount of divinyl benzene, ethylene glycol diacrylate, butane diol diacrylate, styrene, acrylonitrile or methyl vinyl ether.  The alkyl derivatives of styrene and acrylonitrile used as grafting monomers or in copolymer (B) are, e.g. a -methyl styrene, a nuclearly substituted alkyl styrene or methacrylonitrile. Polymers (A) and (B) are preferably prepared in aqueous emulsion using peroxy or Redex catalyst. The polypropylene glycol is incorporated in the composition by (1) mixing with a coagulate of latices of (A) and (B), (2) working into a dry mixture of (A) and (B) or (3) mixing an emulsion of (C) with latices of (A) and (B), coagulating the resulting mixture and compacting or consolidating the coagulate, to which conventional additives, e.g. stearates and waxes may be added prior to further processing.  In the examples, graft polymer (A) is formed by grafting styrene and acrylonitrile on to a copolymer of butadiene with n-butyl acrylate, methyl methacrylate, di-n-butyl fumarate, or a mixture of n-butyl acrylate and divinyl benzene; (B) is a copolymer of styrene, or a -methyl styrene, and acrylonitrile and (C) is a branched polypropylene glycol or a linear polypropylene glycol, or the monomethyl ether or the diacetate of the latter.

Title: Improvements in or relating to friction material and method of making the same
IPC: F16D69/02
Filed: 1931-12-08
Abstract: 380,310. Friction material. COLT'S PATENT FIRE ARMS MANUFACTURING CO., 17, Van Dyke Avenue, Hartford, Connecticut, U.S.A.-(Assignees of Whitworth, H. ; 147, Zion Street, Hartford, Connecticut, U.S.A.) Dec. 8, 1931, No. 34031. Convention date, Dec. 19, 1930. Drawings to Specification. [Class 103 (i).] Friction material particularly adapted for use as a brake lining comprises unwoven sheet form and having perforations extending fibrous material and a binder, heat cured in partially therethrough from one or both surfaces, the perforations being formed prior to curing and remaining in the completed friction material. A method of making the material comprises (1) mixing a plastic mass containing unwoven fibrous material, e.g. asbestos, a binder preferably consisting in part of rubber and adapted to be cured when heated to a prescribed temperature, a vaporizable liquid, including a solvent, e.g. gasoline or naphtha, for the binder, and sulphur and other substances for effecting rapid curing of the binder, (2) forming the mass into a sheet and at the same time effecting vaporization of most of the liquid, (3) cutting the sheet into strips, in the case of brake linings, so that the fibres extend longitudinally of the strips, (4) perforating one surface of each strip by passing the strip between a smooth roller and a spiked roller, (5) drying the strip at a temperature below the curing temperature of the binder so as to vaporize the remainder of the liquid and expel it through the perforations, (6) perforating the strip on the opposite surface and again drying it, and (7) curing the strip preferably under pressure. If desired the first drying operation may be omitted and the sheet perforated on both sides and dried by a single operation. The strip may be used as a brake lining following the drying operation or operations, so that the heat developed during actual use effects the final curing. The mass is formed into a sheet by passing it between two rollers of different sizes, the material adhering to the larger roller in successive layers as the smaller roller is withdrawn, the fibres of the material being arranged circumferentially of the larger roll. During the perforating operation the fibres adjacent the perforations are displaced transversely to interlock with adjacent fibres and thus serve to prevent splitting of the strip. The perforations also make the strip flexible and may serve to collect water if the brake is applied in the presence of moisture.

Filed: 1962-09-05
Abstract: 983, 265. Automatic control. SIEMENS-SCHUCKERTWERKE A.G. Sept. 5, 1962 [Sept. 6,1961 ], No. 34096/62. Heading G3R. In an arrangement for controlling the voltage or reactive power of a synchronous machine 1, Fig. 1, supplying a system 4 through a transformer 3 an exciter 2 is controlled through a variable amplifier 7 by an error signal from a comparator 6. The comparator is fed with an input signal, from an element 5, dependent on the rotor angle defined as the angle between the instantaneous angular position of the rotor and one of the vectors of the supply voltage, and a reference input signal from a slider of a potentiometer 8 positioned by a servomotor 9. The servomotor 9 is energized from a regulator 10, Fig. 2, in dependence on the difference between the actual line voltage, or reactive power, V and a desired valve pre-set by the tension F of a spring (not shown). To prevent the rotor angle exceeding a value determined by the transient stability limit of the machine a polarized relay 13 opens the circuit of the servomotor when the slider voltage exceeds a voltage, across a resistor 14, dependent on the real power or current supplied by the machine as determined by a device 11. When the output of the regulator 10 is such as to lower the reference input signal a winding 15 of the relay causes the servomotor to be reconnected to the regulator 10.

Abstract: 321,841. Barros, J. Nov. 24, 1928. Aircraft instruments.-An instrument for automatically giving to the pilot of an aircraft an audible warning when the angle of incidence of his machine is such that stalling will occur, comprises a syren &c. let into the inter-cockpit communication tube or otherwise arranged to be audible in the pilot's acoustic telephones, the supply of air to the syren being controlled by a pivoted valve in such a way that the air supply is normally cut off but the valve is moved to allow air to pass to the syren when. a predetermined angle of incidence is attained. The valve 7 is connected by parallel linkage 8 to pivots 10, 10<1> and is set at an angle to the horizontal such that the air pressure will normally cause it to close the opening 9 of an air conduit 6. The air pressure also acts on a vane 11 mounted on the pivot 10 and the parts are so arranged that when the critical angle of incidence approaches the pressure on the vane 11 overcomes the downward pressure on the valve 7 and the latter is lifted from its seating to allow air to pass through the conduit 6 to a syren let into the inter-cockpit communication tube. The surface 61 of the conduit is cambered to assist the air to flow evenly. A balancing weight 12 may be fixed to the axis 10<1>. The device is adjustably attached to a strut by a saddle 15 to which it is pivoted, and straps 17 provided with turnbuckles 18. In order to render the warning device inoperative when the aeroplane is landing a cut-off valve may be fitted in the tube through which air passes to the syren, this valve being operated when the control column is pulled right back.
