Title: Improvements relating to drive shaft clutch mechanism
IPC: F16D47/00
Filed: 1956-08-27
Abstract: 790,981. Washing-machines. GENERAL ELECTRIC CO. Aug. 27, 1956 [Aug. 26, 1955], No. 26133/56. Class 138 (2). [Also in Group XXIV] In a drive mechanism for a washing-machine a motor 21 is used to selectively drive either an agitator 8 or a centrifugal dryer tube 7. An outer case 2 has a channel cross member 3 with a resilient block 4 carrying a U-shaped frame 20 which supports a plate 18 carrying the motor 21, the agitator drive mechanism 22 and a discharge pump. The tub 7 is supported on a tubular spin shaft 14.mounted in a support sleeve 15 which is carried on a structural plate 16. Plate 16 is supported by posts 17 on the plate 18 and a plurality of tension springs 23 maintain the mechanism in a normally vertical position. A belt 25 extends between a motor pulley 26 and an agitator pulley 27. Rotation of an agitator drive shaft 28 is converted to oscillatory motion of a dog clutch member 30 on a stub shaft 31 by gearing 29. Concentric with the stub shaft 31 is an agitator shaft 32 extending through the tubular spin shaft 14. The upper end of shaft 32 (carries the agitator 8 and the lower end is splined and slidably carries a drive collar 52 with clutch teeth 66 for engagement with teeth 67 on the clutch member 30. A second pulley 33 fixed to the motor shaft is belted to a pulley 34 which is idly journalled on the shaft 32. The smooth upper surface of the pulley 34 carries a plurality of friction shoes 47 each pivoted at 48, Fig. 8 (not shown), at one end for centrifugal engagement with the wall of a clutch element 43 which is fixed to the tubular spin shaft 14. A plate 51 freely rotatably carried by the driving sleeve 32 has cam arms 53 which pass freely through slots 54 in the pulley 34 and enter slots 55 in the shoes 47 to engage cam faces 57. With the plate 51 in the raised position the cam faces 56 are out of contact with the shoes 47 allowing free centrifugal engagement of the latter with the clutch element 43. Lowering the plate 51 disengages the spin clutch and engages the agitator drive clutch 66, 67. The shifting of the plate 51 and sleeve 52 may be accomplished through a yoke 59 on a lever 58 controlled by a solenoid 64.

Apparatus for attaching a stud fastener member or a socket fastener member having a base portion of synthetic thermoplastic material to a support composed of leather, wood or other material having pores or apertures on at least one surface, comprises fastener-member-storing means, transfer means and heat sealing means, the transfer means being operable to transfer a fastener member from the storing means to the sealing means, which latter is operable to fuse the base portion of a fastener member to the surface of the support. As shown, the apparatus is used to attach stud and socket members 4, 5, moulded from thermoplastic synthetic resinous material, to parts of a garment 1 each of which includes a layer of woven fabric 2 and a lining of plastic sheet material 3. The stud and socket members are fed from respective hoppers 12 and 13, Fig. 3, through escape mechanism 14 on to a slide 10 reciprocably mounted on a bed plate 6. The slide is provided with six apertures for receiving the fastener members. The apertures beneath the hopper 12 have stud members assembled therein and the other three apertures have socket members assembled therein beneath press units 20 mounted on the lower end of a solenoid-operated ram 8. In operation, the support to which the fastener members are to be attached is positioned over the socket members, the ram operated, and an electric heating unit energized to press and fuse the flanges of the socket members to the support. The ram and heating unit are then de-energized, the support removed, and the slide 10 moved to position the stud members beneath the ram, where they are similarly attached to their support. As the slide reaches its position below the hopper 13, pins 21 on the slide actuate levers associated with the escape mechanism 14 to effect release of the lowermost sockets in chutes 13a from the hopper 13, into the apertures of the slide. Pins 22 on the slide actuate levers associated with stud chutes 12a to release studs to a lowermost position where they are retained by an arm of the escape mechanism until released into the apertures of the slide by the pins 22 as the slide is returned to the position shown. The apparatus may be adapted to secure single fastener members and both hoppers 12, 13 may contain either stud or socket members. The apparatus may be arranged to perform all steps of the cycle of operations in timed sequence and each cycle of operation may be automatically repeated. The ram may be other than solenoid-operated. Also, the ram and slide may be manually-operated.

Title: Improvements in or relating to ceramic capacitors and capacitive elements
Inventor: WINDEBANK ROBERT WILLIAM
IPC: H01L41/39
Filed: 1957-08-20
Abstract: A capacitative or piezo-electric capacitative element the dielectric of which is formed by flame spraying of a titanate material, the formed dielectric having ferro-electric properties. The material used for spraying may be preformed barium titanate already exhibiting perovskite type structure and ferro-electric properties before spraying or it may comprise constituents e.g. barium oxide or carbonate or titanium dioxide forming the titanate ceramics, the material then not having a perovskite structure which is formed by the flame spraying process.  Strontium titanate, tantalum oxide, lanthanum oxide and cerium oxide are mentioned as ingredients which may be added to barium titanate to increase the permitivity.  The materials used for spraying are preformed from the raw ingredients by firing.  The capacitor is made by spraying the dielectric directly on a conducting substrate to form one electrode e.g. aluminium, steel, silver coated metal aluminium foil, platinum, heatstable alloy, conducting ceramic. Alternatively, the ceramic may be sprayed on to a support of metal, refractory, paper, or wax from which it is subsequently detached.  The component may subsequently be fired, temperatures of 1250 DEG C.-1400 DEG C. and 500 DEG C. being referred to, to increase its density and therefore its capacity.  It may first be detached from its support or the latter may be of wax so that it melts during firing.  It is stated in the earlier Provisional Specification that soft or hard magnetic ferrite ceramics may be fired by a similar process.  In the formation of a piezo-electric capacitor for use in gramophone pickups or strain gauges, the ceramic is flame sprayed on each side of a conductor which remains a part of the element.

Abstract: 319,761. British Talking Pictures, Ltd., (Assignees off Forest, L. de). Sept. 28, 1928, [Convention date]. Sound - reproducing apparatus associated with kinematographs; optical apparatus ; optical records.-In combined motion picture and soundreproducing apparatus in which separate films are used for the sound and picture records respectively, the films are superposed and wound on to one feed spool, and after passage through the apparatus are preferably wound on to a single take-up spool. Any desired number of separate sound-traces may be formed on the sound-film, and each sound-trace may be associated with a separate reproducing system. In the apparatus shown, a sound-film S and a picture film P pass together from a reel 3 over a sprocket 4. After leaving this sprocket, the film P passes through a gate at the end of a tube 29 containing an optical projecting system, a light source such as an arc being mounted in a casing 28. The picture-film is intermittently moved through the gate, and then passes over sprockets and rollers 30, 31, 16, 17, to a take-up reel 18. The. soundfilm S is separated from the film P between the sprockets 4, 16, and is guided by flanged spools 6, 8 and a roller 7 past the tube 29 and out of contact therewith. Before reaching the sprocket 16, by which it is fed together with the film P to the reel 18, the film S is drawn by a large smooth roller 11 through a guide 10 in a soundreproducing device. The guide comprises two plates, one of which is pressed by springs against the film. The sound-film, in the arrangement shown, bears four independent sound-traces 40, Fig. 2, running side by side along the film. These may, for example, be records produced by using separate microphones for picking up sounds from different groups of instruments in an orchestra. The records are separately and simultaneously reproduced by using a separate light source 22, lens system 24, and light-sensitive cell 26 for each record. The light sources 22, mounted in a casing 21, preferably consist of small lamps with straight filaments. Each optical system 24 comprises lenses and slits mounted in a tube, the light from each source being focused on the slit and a reduced image of the slit being focused on the record. The systems 24 and cells 26 are staggered, as shown in Fig. 2. The cells 26 are connected to amplifiers 43 operating loud-speakers 44, each of the latter being preferably adapted to suit the characteristics of the record with which it deals.

Title: Polyoxyalkylene products
IPC: C08G65/28
Filed: 1956-08-30
Abstract: Poly-oxyalkylene glycol mono ethers suitable for use as detergents in laundering compositions and for emulsifying aromatic compounds in aqueous media are obtained by reacting a monohydric alcohol having no reactive hydrogen other than that of the hydroxyl group with a mixture of ethylene oxide and 1,2-propylene oxide in weight ratios between 5 : 95 and 15 : 85 until a hydrophobic product having an average molecular weight of 1000 is obtained and then reacting this product with ethylene oxide until the weight ratios of the hydrophilic oxyethylene chain to the hydrophobic product lie between 0.8 : 1 and 1.2 : 1.  Monohydroxy alcohols specified are n-butanol, 2-ethylhexanol, methanol, ethanol, n - propanol, iso - butanol, 2 - ethyl butanol, n-heptanol, isopropanol.  The reaction is preferably carried out under substantially anhydrous conditions and in presence of a catalyst, e.g. NaOH, KOH, or alcoholates and at temperatures of 80-160 DEG  C.  The mixture of oxides is introduced at such a rate that a substantially uniform pressure of 5-50 lbs. p.s.i. is maintained in the reactor which is preferably filled with an inert gas, e.g. nitrogen.  In Examples: (1) 480 gs. butanol containing 30 gs. sodium dissolved therein were heated to 110-115 DEG  C. in a reactor pressurized with nitrogen, and a mixture of 893 gs. ethylene oxide and 16,967 gs. propylene oxide added.  After the pressure had dropped, the hydrophobe polymer obtained was found to have a molecular weight of 1462 and was then further treated at 115 DEG  C. with 17,606 gs. ethylene oxide.  The product had a soil removal efficiency of 182% as compared with the dodecylbenzene sulphonate standard; (2)-(4) the reaction conditions were similar but the proportions of ethylene oxide to propylene oxide are varied; (5) 2-ethylhexanol is used as the monohydric alcohol.

IPC: H04L27/233
Filed: 1929-08-30
Abstract: 318,209. Marconi's Wireless Telegraph Co., Ltd., (Assignees of Weagent, R. A.). Aug. 30, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Multiplex signalling; secret systems ; atmospherics, limiting.-Two or more C.W. signals are imposed on different outof-phase components of the same carrier-wave, and are received separately by discriminating between the different phases. In reception the system also operates differentially against atmospheric disturbances, the extent of exclusion being substantially similar to that secured by using a directional aerial. Transmission is secret since no ordinary receiver will distinguish between the different signals. In transmission, Fig. 1, a constant-frequency generator CO is coupled to the aerial N through amplifiers HP1, HP2 arranged in two separate channels, one of which comprises a phase-shifter PS imparting a phase-difference of 90. Each channel is separately modulated at M1, M2. In reception, Fig. 2, the aerial is coupled to two similar amplifying and detecting systems A, B comprising valves 4, 5, 19, 20 in balanced or push-pull relation. A local oscillator 11 of the same frequency as the received carrier is coupled directly to the coil 9 in system A and through a 90 phaseshifter 11<1> to the coil 9 in system B. In these circumstances each receiver A, B is responsive to one of the modulated transmissions and unresponsive to the others, so that both messages are received simultaneously and independently. Reception in each case is due to the 90 phase difference maintained between the local oscillations from generator 11 and the incoming waves which produces a direct current potential across the points A1, A2 and B1, B2. A second local oscillator 23 coupled to the output from the valves 4, 5 renders the received signals audible in the phones 27. Alternatively, direct-current responsive devices D.C.A., D.C.B. may be inserted in circuit as shown.
