Title: Automatic change-speed transmission
IPC: F16H47/08
Filed: 1964-09-03
Abstract: 1,018,539. Friction clutches. FORD MOTOR CO. Ltd. Sept. 3, 1964 [Oct. 4, 1963], No. 36068/64. Heading F2C. An automatic change-speed planetary gear for a motor car &c. includes a friction clutch having multidiscs 70 engaged for intermediate ratio and direct drive by admitting liquid under a relatively low pressure (less than 150 p.s.i.) through a shaft duct 140 to a ring-shaped working chamber between a thickened hub 118 and the radially inner part 122 of an axially-slidable piston 64. During reverse drive, the pressure is increased (to 200 p.s.i.) and then opens spring- closed valves 144, through which liquid passes to pipes 154 in the hub and thence to a second working chamber between the radially outer part 120 of the piston 64 and the drum 60 of the clutch, thereby engaging the multidiscs 70 more firmly. The multidiscs 70 connect the clutch drum 60 and an extension 56 of the drum 38 of a preceding hydraulically-engaged multidisc clutch. Passages 152 to the rear of the valves 144 lead into the casing of the change-speed gear. The piston 64 is biased in the clutch-disengaging direction by springs 132. The planetary gear in which the clutch is described is similar to that of Specification 912,399 (Division XXIV), and comprises an hydrodynamic torque converter driving through one clutch to a first sun gear, through another clutch (the clutch 70) to a second sun gear, intermeshing planet pinions on a carrier held against reverse rotation by a one-way detent, and an output driven ring gear. Band-brakes are operative to station the second sun gear and the' planet carrier. Three forward ratios and reverse are obtained. Control pressure, which is supplied to the clutch 70, depends upon engine torque demand and output speed.

Abstract: 941,678. Reactor control rods. A. REYROLLE & CO. Ltd. Feb. 9, 1960 [Nov. 10, 1958], No. 36086/58. Heading G6C. [Also in Division E2] A clutch is provided in the transmission mechanism between a control rod suspension and its driving motor, and the clutch can be mechanically disengaged by an associated release mechanism responsive to abnormal conditions in the reactor. The clutch 13 shown in Fig. 1 comprises a driven inner shaft 16 coupled by a ball lock to a cylinder 24 forming part of the rotor of an electric motor. The balls of the lock are held in the locked position by a spring-biased plunger 33; the plunger is coupled to a bellows 62 one side of which communicates directly with the reactor coolant and the other side of which communicates through a throttle valve 68 with the coolant so that a rapid fall in coolant pressure will depress the bellows and plunger and release the balls so that the shaft 16 is free to rotate. An eddycurrent brake 42, 43 is provided. The whole mechanism is housed in a pressure-tight head attached to the reactor pressure vessel. A spindle 80 with a pinion 83 is provided so that the control rod can be moved by hand if necessary. Specification 908, 059 is referred to.

Title: Improvements in or relating to machines for the continuous production of flat bags
Inventor: ENTZMINGER AUGUSTE
IPC: B31B23/00
Filed: 1960-10-22
Abstract: 918,381. Bag-making machines. ATELIERS DE CONSTRUCTIONS MECANIQUES C. & A. HOLWEG. S. a. r. L. Oct. 22, 1960, No. 36320/60. Class 94(2). In a machine for the production of flat bags a web is perforated along transverse lines, folded longitudinally, torn along the lines of perforation to produce bag lengths which are then folded transverse to the web length and sealed to form a complete bag. During machine operation the perforator is adjustable transversely of the web and the pressure on the web of webdrawing rollers is adjustable and may be released without altering this adjustment. In one embodiment (Figs. 1 and 2) a web 1 is fed from a roll by rollers 7, 8 the driving pressure being adjustable and releasable by means 9-13. The web continues past a glueing roller 15, perforating rollers 16, 17, transverse scoring device 21 and a guide roller 22 mounted eccentrically so as to enable the web length from the reel to be adjusted for timing purposes. Next follows a tube forming device E and a second pair of drive rollers 27, 28 the pressure between which is adjustable by collars 39 and releaseable by cam means 41. The tube passes between a pair of rollers 43, 44 for periodically gripping it to enable a faster running pair of rollers 50, 51 to tear off bag lengths. Waste material between bags is torn off by faster running rollers 46, 47 co-operating with the rollers 50, 51. The roller 51 is hollow and contains rows of spikes which spring through slots in the roller and impale the waste, the spikes being withdrawn under the action of a cam on further rotation of the roller releasing the waste, the waste being stripped off by a rotating rake, Fig. 8 (not shown). The bag lengths then pass to conventional bottom flap folding and glueing mechanism K. In another embodiment, Fig. 3 (not shown), for producing bags as shown in Fig. 4 the tube forming device E is replaced by longitudinal creasing, cutting and folding devices. Notches between web margins which are folded over to form glue flaps are cut out, suction nozzles removing the waste. Devices turn in the edges of the web and apply adhesive to them after which the bag is doubled transversely by means not detailed.
Patent GB-626353-A (GB)
Title: Improvements in and relating to methods for preparing organo-silicon halides
IPC: C07F7/16
Filed: 1946-12-09
Abstract: <PICT:0626353/IV (b)/1> Organo-halogen-silones are prepared by separately introducing into a reaction zone a hydrocarbon halide and a finely divided mass comprising silicon alone or intimately associated with a metallic catalyst for the reaction between the hydrocarbon halide and silicon, the reaction zone being heated to a temperature of p  200 DEG  C. to 500 DEG  C., conveying the mass upwardly through the reaction zone in the region adjacent to the side walls defining the same, contacting the moving mass continuously with the hydrocarbon halide, allowing the mass containing unreacted silicon when its upward travel has ceased to fall downwardly through the central portion of the zone in contact with the hydrocarbon halide, and withdrawing from the reaction zone the organo - halogen - silanes.  The mixture of metallic catalyst and silicon may be moved spirally upward through the reaction zone in the region adjacent to the inner walls.  Organo-halogen-silanes which may be prepared are methylchlorosilanes, ethyl-, propyl-, butyl-, amyl-, isoamyl- or hexyl-silicon chlorides or bromides, aryl silicon halides such as phenyl silicon chlorides or bromides, aryl-substituted aliphatic silicon halides such as phenylethyl or phenylpropyl silicon halides, aliphatic-substitued aryl silicon halides such as tolyl silicon halides or xylyl silicon halides. Suitable metallic catalysts for the reaction between the hydrocarbon halide and silicon are copper, nickel, tin, antimony, manganese or titanium.  In an example, gaseous methyl chloride and a powdered mass comprising silicon and copper are reacted to form methyltrichloro- and dimethyldichloro-silane.  The silicon-copper mixture is introduced through inlet 14 of Fig. 1 into the heated reaction chamber 11 and is stirred continuously by the revolving ribbon conveyer 17 so that the mixture on top of the flight 18 is carried vertically up the tube adjacent to the wall of the reactor.  Methyl chloride is introduced continuously through inlet 15 and reacts with the silicon adjacent to the walls of the reactor. Unreacted silicon falls down the annular space 32 in the central portion of the reactor and is raised up through the reactor again on ribbon conveyer 17.  Effluent vapours pass off through conduit 23 and unreacted methyl chloride is separated from the methylchlorosilones and may be recycled.  Specifications 575,668 and 590,654 are referred to.  The Specification as open to inspection under Sect. 91 refers to the preparation of mixed organo-silicon halides such as methyl ethyl silicon halides, methyl phenyl silicon halides or ethyl phenyl silicon halides and alkylene silicon halides such as ethylene silicon chlorides and others described in Specification 3139/43, as open to inspection under Sect. 91 by the above method. Organo silicates such as methyl silicate may be prepared by employing methyl alcohol instead of a hydrocarbon halide by the above method.  This subject-matter does not appear in the Specification as accepted.

Abstract: 1,017,240. Aerials. WESTERN ELECTRIC CO. Inc. Sept. 26, 1962 [Oct. 5, 1961], No. 36677/62. Heading H4A. A Cassagrainian aerial system comprises a primary feed 10 filling an aperture 25 of diameter d in a primary concave paraboloidal reflector 20 facing a secondary convex reflecting surface 40 and spaced a distance x therefrom where x<d<SP>2</SP>/ 2 # (e.g. d = 14X, x = 30#) such that the secondary reflector 40 is in the near zone of the feed 10 thereby reducing spillover at the reflectors 20 and 40. As shown, the secondary reflecting surface 40 is paraboloidal, the primary feed 10 comprises a circular waveguide 14, conical horn section 18 and concave paraboloidal section 22 producing a substantially collimated beam having a plane wavefront, the diameters of the aperture 25 and secondary reflector 40 being substantially equal; alternatively, a plane wavefront may be produced by a small paraboloidal reflector fed in a conventional manner, or a diverging wavefront may be produced by a waveguide horn, or the paraboloidal section 22 of the feed 10 may be replaced by an ellipsoidal section to produce a converging wavefront, the contour of the secondary reflecting surface 40 being suitably modified. In order to reduce aperture blocking by the secondary reflector structure 30, radiation from the primary feed 10 incident on the central portion of the secondary reflecting surface 40 passes through an aperture therein and is directed on to a concave paraboloidal reflecting surface 42 of the secondary reflecting structure 30 via a conical horn 32, circular waveguide section 34 containing a dielectric phasing slab 38 and a reflecting cup 36 located at the focus 28 of the primary reflector 20. Suitable valves for the diameters of the primary and secondary reflectors 20 and 40 are 100# and 15# respectively. The aerial may be used for transmission to or reception from a communication satellite.

Title: Improvements in or relating to the extrusion of tubular or other sections
IPC: B21C35/04
Filed: 1954-12-20
Abstract: 753,207. Extruding. HERLAN, F. Dec. 20, 1954 [Dec. 22, 1953], No. 36684/54. Class 83(4). In the extrusion of tubular or other sections from hollow billets 1, the discard remaining in the billet container 2 at the end of extrusion is automatically severed from the extruded product by the release of stored energy, the discard is then withdrawn from the container on the return stroke of press ram 4 and is removed therefrom by a stripper plate 9, and the extruded product is ejected from the press by the succeeding extruded product being formed on the next stroke of the press. The press ram 4 has slidably mounted therein a punch 5 having a reduced forward end which during extrusion acts as a mandrel. The punch is biased forwardly by a series of springs 6 but during extrusion is held fixed relative to the ram 4 by the shoulder at the end of its reduced end portion engaging the rear end of the billet 1. At the end of extrusion the force of the springs 6 is sufficient to force the shoulder through the thin discard remaining in the container and thus to sever it from the extruded product. A recess or neck 11 at the periphery of the forward conical end surface of the ram 4 receives some of the billet metal during extrusion whereby the discard adheres to the ram and is withdrawn thereby from the container and subsequently removed by the stripper plate 9.

Title: Improvements in coil developing apparatus
IPC: H02K15/04
Filed: 1969-07-22
Abstract: 1,270,290. Winding stators; shearing. GENERAL ELECTRIC CO. 22 July, 1969 [29 July, 1968], No. 36820/69. Headings B3A and B3W.  Apparatus for winding a coil 62 for insertion  into a magnetic core 184 comprises a coil turn  forming assembly and coil injection equipment 20, the latter including a plurality of blades defining turn receiving slots, and means for guiding turns of wire into the slots during winding so as to form a coil directly in the equipment 20. The coil injection equipment 20 is located under a winding head 19 and a jump tube 51 is actuated to drive the winding head downwardly to position a push-plate 117 so that an extension 150 thereon abuts a first trip-bar 143, Fig. 11. A first snap-out plate 39 is concurrently released by the winding head and engaged by spring pressure against a first blade 30 of the equipment 20 in alignment with a first turn-gauging step 58, Fig. 5. A flyer 22 places turns of wire on the step 58 and after about three turns have been wound the start end of wire is released from a cutter and holder 23. When the required number of turns has been wound, as determined by a punched tape in a reader 127, a solenoid 165 is actuated so that a pin 156 engages the bar 143. The oscillatory movement of a mechanism 155 pivots the bar to allow the extension 150 to engage a second trip-bar 144. The concurrent downward movement of the winding head releases a second snap-out plate 40 to bring it into the path of the wire 62 together with the gauging step 57. The remaining coils are similarly wound and as the flyer 22 rotates around each turn-gauging step, the wire is laid on a bevel 61 of each step and it pushes the preceding turn into the openings of the injection equipment 20. The tape also controls the number of slow-down turns included at the end of the turn count of the last coil, which is necessary to allow the cutter and holder 23 to be brought into the wire path during the last turn. A mark 133 on a translucent disc 131 interrupts a light source to a photo-electric cell 135 to provide a turn count and another mark 134 co-operating with a photo-electric cell 136 indicates the position of the flyer head. The cutter and holder 23 is provided with a hook 94 having a cutting edge 95, and when the hook is engaged in a cutting block 96, the edge 95 will shear the wire. At the end of the total turn count, a stripper 24 clears the coil form assembly 21 of any remaining turns and pushes the turns into the injection equipment 20 so that they will not spring out. The stripper is then returned and the jump tube 51 and head 19 are raised thereby resetting the trip bars 143- 146 and the snap-out plates 39-43. The injection equipment 20 is then indexed 180 degrees and the coil turns of a second pole are wound in sequence. When the second coil group has been wound the equipment 20 is moved to a coil injecting station where the coil groups are axially inserted into the stator 184.

Abstract: 819,893. Electric tests. MINNEAPOLISHONEYWELL REGULATOR CO. Nov. 29, 1957 [Dec. 3, 1956], No. 37305/57. Class 37. Conductive or magnetic bodies on a conveyer are detected by anelectrical bridge circuit have ing four arms each constituted by an inductance coil; two of the coils are wound on one core member and two on another, the cores being so arranged that when one is placed with its poles near enough for the flux to be affected by the body on the conveyer, the other has its pole out of range of such influence. Fig. 3 shows one arrangement of the four coils 31 ... 34 of which 31, 34 on core 82 form opposite arms of the bridge circuit and 32, 33 on core 83 form the other pair of arms. Cores 82, 83 are at right angles and the object to be detected passes the free poles of core 82 so that the inductance of coils 31, 34 is changed. This produces an output current in the bridge diagonal which is rectified by full wave rectifier 36 (Fig. 2) and fed to control windings 50 of normally selfsaturating magnetic amplifiers 52. This reduces the saturation cutting off the signal applied by output windings 53 through rectifiers 55 to control windings 65 of a further magnetic amplifier. This allows the further stage to saturate feeding an output to a control relay or load device 80 which may control the conveyer.
