Title: Drive rivet assembling machine
Inventor: WILSON RAYMOND OWEN
IPC: B21K1/58
Filed: 1961-10-06
Abstract: 916,140. Making tubular pinned rivets; assembling force fits. OLYMPIC SCREW & RIVET CORPORATION. Oct. 6, 1961, No. 36070/61. Classes 83 (2) and 83 (4). [Also in Group XXV] A machine for assembling the sleeve and pin of a drive rivet comprises a first disc 14 having peripheral sleeve carrying stations and intermittent drive, a second disc 13 having peripheral sleeve carrying stations from which sleeves are transferred to the first disc, a third disc 16 placed above the plane of the first and second discs and having peripheral pin carrying stations which position successive pins above successive sleeves, means 19 for downwardly displacing successive pins into partial engagement in the sleeves, and means 20 for further engaging partially engaged pins. Drive mechanism.-Drive is transmitted from a pulley 30 through shaft 31 to gear 32 which drives gears 33 and 36. Gear 36 drives shaft 35 which actuates a cam and air valve mechanism 18. Gear 33 provides drive for the intermittent rotation of three vertical shafts 38, 45, 53 which support the three discs. Gear 33 has a recessed hub 60 containing friction packing 63 on the other side of which is a ratchetwheel 62 keyed to shaft 34. Gear 33 rotates continuously but the ratchet - wheel normally remains stationary due to engagement of its pawl 68, this being made possible by the clutch 60, 64, 62 slipping. However, a lug 61 on the gear hub 60 strikes a roller 71 mounted on the pawl 68 and lifts the pawl from engagement, thus allowing the clutch to transmit rotary drive to the shaft 34 until the next ratchet tooth is engaged by the pawl. Two gears 75 transmit this rotation to a secondary shaft free to rotate on shaft 31, the secondary shaft driving discs 13 and 16 through bevel gears; shaft 34 drives disc 14 directly through bevel gears 72. Rivet and pin feed and assembly.-Pins P are fed down an inclined shoot 15 into the notches 55 on disc 16 and retained therein during rotary transfer to a position below rammer 82 (Fig. 2) by a guide rail 58 (Fig. 1). An identical feed. and transfer system is used to feed rivets F to. a position below both the pin P and the rammer 82, which, by application of compressed air controlled by the means 18, partially enters pins P into rivets F. Final ramming to the required engagement is carried out by a mechanical linkage ram shown in Fig. 5 at the position shown in Fig. 1. A further pneumatic means 21 may be used to place sealing washers under the rivet heads, and the assembled rivets are finally stripped from the disc 14 by an inclined face 22.

Filed: 1930-12-04
Abstract: <PICT:0363116/III/1> In a process for evaporating liquids containing incrustants the solubility of which decreases with increasing temperature, e.g. brine containing gypsum in solution, by circulating the liquid in apparatus of the separate heater and evaporator type, deposition of salts in the heater is prevented by maintaining the liquid in the heater in the metastable zone, by employing high pressure in the heating zone, by keeping the temperature drop between the medium and the liquid small, by circulating the liquid at high velocity so as to give turbulent flow, and by relieving the supersaturation of the liquid prior to its return to the heating zone.  Brine is circulated from a heater 2 through a pipe 11 to an evaporator 1, the pressure being relieved in two stages by a valve 12, and passage though nozzles 13.  Steam is withdrawn through a pipe 14 and the concentrated liquid is returned through a saturator 4 and pipes 3, 5 to the heater 1 by a pump 6, driven by a turbine 7, the exhaust steam from which is led through a pipe 9 to the heater, extra steam being supplied through a pipe 10.  The saturator A may alternatively be situated between the valve 12 and the nozzles 13. The velocity of the liquid in the heater should be at least 1 metre per second.  U.S.A. Specification 1,006,823 is referred to.

Abstract: 1326072 Raising liquids by suction MEDICAL DEVELOPMENT CORP 29 July 1970 [21 Aug 1969] 36744/70 Heading F1R [Also in Division A5] In a disposable surgical bottle 10 which comprises a container 11 with a cover 12 provided with respective body fluid and vacuum conduits 20, 19 means are provided co-acting with the body fluid conduit 20 to prevent back flow siphoning of fluid. As shown, an inlet tube 36 depends from the cover 12 and has one or more apertures B which ensure, should the pressure in the container 11 rise, equal pressures in the tube 36 and the remainder of the container 11 so as to prevent back flow of body fluid to the patient. To collect body fluid, air is withdrawn from the container 11 by a vacuum system 21 and fluid enters the container through a tube 32 and the conduit 20. When the vacuum system 21 is not operating any increase in pressure which might occur above the level of the body fluid is transmitted through the apertures B and prevents the column of fluid in the tube 36 and that in the tube 32 from flowing back to the patient. After the container has been filled tube 23 is disconnected from the conduit 19, the free end of the tube 32 is attached thereto and the bottle 10 discarded. In a modification the inlet tube (36'), Fig.2 (not shown), extends just below the lower end of the conduit 20 which may have a check valve to prevent reverse flow.

Abstract: 918,546. Fuel pumps. ENGLISH ELECTRIC CO. Ltd. Oct. 23, 1961 [Oct. 27, 1960], No. 36863/60. Class 102(1). [Also in Group XXVI] In an emergency shut down gear for an internal-combustion engine, a spragging pin 15 capable of locking the tappet assembly of a fuel pump 1 is normally held back by fluid pressure against spring bias and this fluid pressure is controlled by a spring loaded valve 35 under the action of a mechanical overspeed tripping device 2 which in normal operation holds this valve in a position securing access of fluid pressure to the spragging pin but in case of overspeeding of the engine triggers off the valve to a position relieving fluid pressure on the spragging pin as shown in case of overspeeding the trip latch 21 is swung anticlockwise by conventional overspeed tripping means (not shown) when the trip latch 21 releases the cam 27 the spring 39 pushes the valve 35 down so that it obturates the inlet port 31 and establishes communication between the outlet port 32 and the drain port 34. The arrangement is particularly suited to multicylinder engines where more than one multi element fuel pump is fitted and where these pumps are arranged remote from one another for instance on a V-engine with the pumps outboard. The fluid pressure controlling the spragging pin may be derived from the engine lubrication system or from an independent closed hydraulic circuit.
