Title: Machine for inserting fasteners
IPC: D05B5/00
Filed: 1972-05-30
Abstract: 1401684 Inserting tags DENNISON MFG CO Ltd 30 May 1972 [27 May 1971] 25283/72 Heading D1G Apparatus for dispersing fasteners 54 having a head 54a Fig. 13, and a filament extending from the head, comprises a pair of clamping jaws 20, 21 Fig. 1 relatively movable to clamp material 23 therebetween a needle 25 having a longitudinal slot and movable relative to the jaws to penetrate material held by the jaws and a plunger 51 movable to force the head of a fastener along the slot of the needle. In a first embodiment a movable jaw 21 is actuated by a compressed air piston 31, and normally urged rearwardly by a spring 42. The inner jaw includes racks 22a, 22b which engage gears 44 coupled in turn to a larger diameter gear 45. The gears are rotatable within a telescoping member 26. The jaw 21 is urged forwardly by a spring 47 which is stronger than spring 42, forward movement being limited by a stop pin 49. In operation, fasteners 54 are threaded into a slot 61. Actuation of the piston 31 causes the telescoping member 26 and jaw 21 to move forward, spring 42 first compressing. The needle 25 penetrates the material layers via jaw cut-outs 20e, 21e Fig. 8 and the plunger 51 moves forward at a greater speed due to rotation of the gears and movement of the rack 50. The fastener 54 is separated from the carrier 57 and passes through the material The needle has the usual V-shaped cut-off groove. Retraction follows, and the return of the telescoping member causes an indexing wheel 70 to position the next fastener in front of the needle when a rod 80 engages a plug 82 and holds the indexer 75. A second embodiment is hand operated by handles 100, 103 Fig. 14, with the work held by jaws 102, 106 which have cut-outs 102a 106a for the needle 120. A plunger 125 has teeth 125a and cooperates with a wheel 116. An indexing wheel 130 and pusher 137 are provided and when the handles are released a rack 11 retracts (to the left in Fig. 14) returning the plunger 125 and engaging the pusher 137 to rotate the indexing wheel 130 to position the next fastener in front of the needle. A third embodiment is arranged for automatic control with the needle mechanism in a housing 173 which also controls the jaw 176, Fig. 26. A modification to the first embodiment includes a nose guard 152 Fig. 18 and a bracket having inner guide edges 157a to position two sides of a ticket 158 between the jaws. The ticket is held by a binder clip 159.

Title: Improvements in or relating to a process and apparatus for the production of unsaturated hydrocarbons
Inventor: HUGHES EDWARD MORGAN
IPC: C07C4/04
Filed: 1954-09-03
Abstract: <PICT:0819784/IV (b)/1> A process for the pyrolysis of substantially saturated hydrocarbons to produce acetylene and unsaturated hydrocarbons such as ethylene comprises introducing the hydrocarbon in the form of a jet or stream into a closed combustion chamber to impinge upon an obstructing element to form a thin sheet of radially moving hydrocarbon, introducing molecular oxygen into the combustion chamber, effecting a partial combustion of the hydrocarbon, withdrawing the hot combustion products from the chamber and quenching them.  Preferably the cooling of the gases is effected by adiabetic expansion in a gas turbine as disclosed in Specification 711,208.  In a preferred embodiment propane is introduced through a pipe 4 and nozzle 5 into a combustion chamber constituted by circular walls 1 and 2 and impinges on to a cylindrical obstructing element 6. At the same time oxygen or air enters a manifold 8 and is mixed with the propane after passing through inlet ports 7.  The combustion products traverse radial outlet holes 10 into a manifold 11 constituted by a tube 3 and leave by a tube 15 to a radial-flow gas turbine T.  In a modification (not shown) methane and oxygen are combusted and are led to an axial flow gas turbine.  Specification 819,783 also is referred to.

Filed: 1974-05-13
Abstract: 1464865 Data transmission; phase modulation RACAL (SLOUGH) Ltd 13 May 1974 [1 June 1973] 26170/73 Heading H4P In a P.S.K. system to provide smooth transition between one phase position and another, the transition takes place progressively over a finite time by means of an intermediate frequency shift. In the particular embodiment a series of phase displaced outputs are developed one of which is selected in accordance with input bit value; in response to a change in bit value a second frequency is temporarily selected in lieu which is compared in phase with another first frequency output to be substituted, changeover taking place when the monitored phase difference is equal to the required phase difference between first frequency outputs. Output of oscillator 10 is divided in frequency at 11, 12 which produces a series of phase displaced outputs (e.g. 180 degrees) 18, 20 which are selected through one of gates 22, 24 by input data 45. Change in bit value is detected at 38 which through bi-stable 44 opens gate 17, admitting pulses from oscillator 10 into another divider 15, 16 producing a slightly higher or lower frequency than 11, 12 and initially in phase inhibits gates 22, 24 and is transmitted through gate 32. When the output from 11, 12 corresponding to the new bit value is in phase with the output from 15, 16 as denoted by l's detectors 50, 52, gate 48 is enabled which resets bi-stable 44 thus blocking gate 17 and opening one of gates 22, 24 corresponding to the new value, outputs from these gates being routed through OR 26. The arrangement is stated to reduce the frequency bandwidth required for transmission line equipment which may be further reduced by a sinusoidal rate of change. The change rate depends on difference between division factors of the dividers.

The clean water flows from the pipe 8 through a branch 14 to a pressure regulator 14 into a manifold 22 acting as the heat exchanger with the geothermal liquid in surrounding conduit 10 and the generated steam passes via a passage 18a to the turbine. After expansion the steam is redirected to flow upwardly through the turbine to the earth's surface 11 through a central conduit 9a. A portion of the clean water passes from the pipe 8 via pipes 13, 17 to form lubricant within a bearing section 6 of the turbine shaft. A control arrangement is described in which the pressure of the clean water entering the steam generator determines the rate of mass flow through the turbine and thereby determines the pumped well water pressure.
