Abstract: 931,951. Road vehicle spring suspensions. METALASTIK Ltd. Sept. 6, 1961 [Nov. 29, 1960], No. 41048/60. Class 108(2). In a road vehicle suspension comprising a leaf spring 13 which supports an axle casing 11 and constrains the latter to deflect in an arcuate path, the stiffness of the suspension under tare loading conditions is decreased by an auxiliary rubber spring system comprising a pair of links 21, 23 connected by rubber pivot members 24, 25 to a bracket 22 fixed to the axle casing 11 and by rubber pivot members 26, 27 to the vehicle chassis 10. Since the ends of the links 21, 23 connected to the bracket 22 are constrained to move in the arcuate path followed by the axle when the spring 13 is deflected axial forces are set up in the links causing radial deflection of the rubber pivot members together with torsional deflection caused by rotation of the links. The axial force in the links is arranged to be compressive under tare load, tensile under full load and zero at an intermediate load. The rubber pivot members 24, 25 comprise cylindrical rubber bushes compressed between outer sleeves formed at the ends of the links 21, 23 and inner sleeves secured between two side plates forming the bracket 22. The rubber pivot member 26 comprises a cylindrical rubber bush compressed between an outer sleeve formed on the link 21 and an inner sleeve mounted on a pin protruding from a bracket bolted to the chassis 10. The rubber pivot member 27 comprises a double bush assembly with an inner cylindrical rubber bush 38 compressed between an inner sleeve mounted on a bracket bolted to the chassis 10 and an intermediate sleeve, and an outer elliptical rubber bush 39 compressed between the intermediate sleeve and an outer elliptical sleeve split along its minor axis and secured by threaded studs 43 welded to a pair of plate members forming the link 23. Alternatively the outer bush may be cylindrical and the inner bush elliptical with its major axis disposed transversely of the link 23. The double bush assembly may be used at either end of the link 23.

Title: Liquid storage tank and liquid removal means
IPC: F17C9/00
Filed: 1961-11-20
Abstract: 959,222. Centrifugal and axial flow pumps. CONCH INTERNATIONAL METHANE Ltd. Nov. 20, 1961 [Jan. 23, 1961], No. 41457/61. Heading F1C. A combination of a storage tank for liquefied gases and pumping means in the tank comprises an outer shell 32 having an outlet 42 and fixed adjacent to the bottom of the tank, an inner shell 60 having an outlet 68, sealing means 76 in the space between the shells 32, 60, a motor driven pump 46 mounted on the inner shell and means for raising or lowering the inner shell into and out of the outer shell. The pump inlet is fitted with a bell 54 and the pump outlet is connected to the outlet 42 by a bellows 72. The edges of the flanges 64, 66 provided on the inner shell 60 and the aligned inner surfaces of the shell 32 are machined to improve sealing between the inner and outer shells. The sealing means 76 may also comprise resilient gaskets having metal rings 78 on the sides opposite flanges 64, 66 and the pressurised liquid from the pump acts on the rings 78 to compress the gaskets. An alternative form of sealing comprises 0-rings retained within annular recesses on the outer wall of the inner shell (Fig. 4 not shown). The pump and inner shell assembly is mounted on a supporting bracket 94 attached to a plate 96. When suspended the weight of the assembly is taken by a spring loaded arm 106 and as a chain 90 is raised by lifting tackle, the arm 106 swings to a vertical position to clear a latching plate 104. On lowering, the asesmbly is guided into the outer shell 32 by a flared portion 40 thereof and rests on an annular flange 38. As the chain 90 is lowered further the arm 106 latches under the plate 104. In an alternative guiding assembly, the inner shell is directly suspended from a cable which passes through a sleeve section, which in its turn is suspended from a further cable. A number of collapsible stabilising arms are pivoted to the sleeve and engage guide rods extending through the depth of the tank. When the sleeve is raised relative to the cable passing therethrough, the stabilising arms collapse to allow them to pass through the tank opening when inserting or removing the pump.

Title: Folding mechanism
IPC: B65B7/28
Filed: 1970-08-28
Abstract: 1275228 Applying caps to containers SIGNODE CORP 28 Aug 1970 [5 Sept 1969] 41592/70 Heading B8C A mechanism for folding a flange 36 on a container 18 and a flange 38 on a closure cap 20 from the configuration shown in Fig. 2 to that shown in Fig. 5 comprises, a first member 32 which engages a portion of the cap flange 38 extending beyond the container flange 36 and which is pivoted about a pin 48 from the Fig. 2 position to a position overlying a second member 34 so as to fold the cap flange 38 over the container flange 36, both the members 32, 34 then being pivoted as a unit about stub shafts 42 to the Fig. 5 position. Arms 40 depending from the second member 34 are pivoted to a support frame by the stubs shafts 42 and rotatably support a shaft 50 to which is secured a link 52 pivotally connected to a second link 54 in turn pivoted to an ear 46 on the first member 32, the ear 46 being pivotally connected to an ear 44 on the second member 34 by the pin 48. The two end-positions of the members 32, 34 are determined by a stop 68 carried by the link 52 abutting either one of two stops 66 carried by one arm 40. The members 32, 34 are pivoted by means of a cylinder 96 having a piston-rod 100 connected to the link 52 by a pin 106 so that retraction of the piston-rod 100 rotates the shaft 50 anticlockwise and causes the linkage 52, 54 to take-up the relative configuration shown in Fig. 5 with the first member 32 overlying the second member 34, movement of the second member 34 being prevented by a spring biased latch arm (72, Figs. 3, 4) which abuts lug 82 on the arm 40, a stop 92, carried by an arm 90 on the link 42, abutting the latch arm (72) and moving it away from the lug 82 on completion of the pivoting movement. Thus, further retraction of the piston-rod 100 cause the members 32, 34 to pivot about the shafts 42 as a unit. Simultaneously with this pivotal movement the container 18 and the cap 20 are lowered by a mechanism (not shown) to a position between spaced guides 110 (only one shown), and a strap 112 is applied around the cap 20 to secure it to the container 18. Alternatively, adhesive may be used.

Filed: 1973-09-11
Abstract: 1393660 Detector circuits COMMISSARIAT A L'ENERGIE ATOMIQUE 11 Sept 1973 [21 Sept 1972] 42583/73 Heading H3Q A sine wave signal demodulator comprises two sample-and-holder circuits 8, 10, Fig. 1, connected in cascade. A circuit 6 driven from the incoming signal generates rectangular pulses B, Fig. 2, each of which coincides with the first half of a positive half-wave of the sine wave signal A in each alternate cycle, which gate the sample-and-hold circuit 8 to produce the output signal C. A second circuit 12 generates a second drive signal D outside the rectangular pulses B and which gate the sample- and-hold circuit 10 to produce the output E. An input filter 4 is provided, from the output A, Fig. 4, of which is generated by circuit 20, Fig. 4, the rectangular wave F of the same frequency. The output F from circuit 20, Fig. 3, is applied (1) to sawtooth generator 22 producing the waveform G and (2) to frequencydivider 24 which produces the waveform H of half frequency and also H which is inverted. Waveforms F, H are applied to the AND gate 26 which has as output the waveform I. The waveform G is applied to the sample-and-hold circuit 28 which is gated by the waveform I and produces as output the waveform J. A fraction k of the waveform G is applied to the negative input of comparator 34, while a fraction k/2 of waveform J is applied to the positive input, the output from comparator 34 comprising the waveforms K. The waveform F, H, K are applied to the AND gate 36, the output of which comprises the waveform B. The gating signal for the sample-and-hold circuit 10 may (1) be derived from the waveform B by means of an inverter 40, or (2) comprise the waveform I. Alternatively it may comprise the output of an AND gate 42 fed with the waveforms F, H.

Title: Method of producing a weld zone of desired cross-sectional shape in charge-carrier-beam welding
IPC: H01J37/147
Filed: 1961-11-29
Abstract: 1,004,356. Electron beam apparatus. UNITED AIRCRAFT CORPORATION. Nov. 29, 1961 [Dec. 6, 1960], No. 42597/61. Heading H1D. [Also in Division B3] In electron beam welding in order to produce a welded seam of desired cross-section, e.g. rectangular, the beam is periodically tilted about an axis parallel to the seam or a plurality of beams are used. In the latter case all the beams may be fixed or one or more may be periodically tilted. The generator has an electromagnetic focusing lens and two deflectors 30, 31 which may be both electromagnetic or one of which may be electrostatic. A work illuminator, a viewing window and an optical viewing system are provided. The control signals for the deflectors 30, 31 may be of square, trapezoidal or sinusoidal form and may be timed to produce greater heating at the margins of the seam. Where an interrupted beam is used, the beam is deflected in the pauses between the pulses. The total deflection may occur in one or in a number of steps and the work feed occurs intermittently when each deflection or set of deflections is completed. Alternatively the work feed may be continuous and an additional deflection of the beam longitudinally of the seam be superimposed to produce the desired intermittent relative movement of the beam and work. A rectangular sectioned seam may be produced by deflecting the beam to produce overlapping fusion zones 35, 36 as shown. An additional deflector may be provided to initially deflect the beam to follow inaccuracies of the seam. Alternatively this effect could be produced by superimposing a D.C. supply on the deflector 30. To produce a wider seam an additional transverse deflection may be superimposed on the tilting deflection. In a modification, the seam is produced from a number of fixed beams, which may be perpendicular or inclined to the work surface and may be from the same or opposite sides of the work.

IPC: F02C9/28
Filed: 1965-10-07
Abstract: 1,066,670. Gas turbine plant. BENDIX CORPORATION. Oct. 7, 1965, No. 42619/65. Heading F1G. A gas turbine engine comprises, Fig. 1 (not shown), a compressor (14) supplying air through a rotary regenerator (30) to a combustion chamber (16) feeding a compressor driving turbine (20) and a separate power turbine (24). Liquid fuel is supplied to the combustion chamber burner (18) by a positive displacement pump 58 driven through gearing 62 by the compressor (14), the fuel passing through three valve controlled orifices in series. The output from the pump 58 passes to a chamber 64 at pressure P 1  and through the first orifice 80 in a tubular member 76, obturated by a slidable sleeve 96 controlled by a compressor speed responsive governor 66, to an outlet 52 at pressure P 2 . The desired speed of governor 66 is set by a lever 94, which moves an abutment 106 of a spring 102. The fuel flows from outlet 52 through conduit 40 to the second orifice 136 obturated by a slide valve 130 moved in response to changes in the compressor outlet air temperature (T  R ) sensed by expansion or contraction of a tube 140. After passing through orifice 136, the fuel flows through conduit 44 at pressure P 3  to the third orifice 172 obturated by a slide valve 174 moved in response to changes in compressor inlet air pressure P a  sensed as a measure of altitude by an evacuated bellows 194. The bellows may be replaced by a fluid filled bellows responsive to inlet air pressure P a  and temperature to give a measure of inlet air density. The fuel flows from orifice 172 through conduit 46 at pressure P 4  to the burner (18). A fuel bypass conduit from the pump outlet chamber 64 to the pump inlet 50 is defined by passages 202, 204, chamber 206, a variable area orifice 208 controlled by a valve 210, and a passage 212. The position of valve 210, and thus the quantity of by-pass flow as well as the fuel pressure P 1  is established as a function of compressor outlet and inlet pressures P c , P a  respectively, applied to opposite sides of a diaphragm 214 connected by a rod 236 to one end of a pivoted lever 242, the other end of which is connected to valve 210 by a rod 264. Valve 210 is mounted in a diaphragm 254 the opposite sides of which are subjected to fuel pressures P 1  and P 4  so that the diaphragm senses the total pressure drop across the orifices 80, 136, 172. A spring 265 holds valve 210 closed at starting of the engine. A pressure relief valve 266 limits fuel pressure P 1 . The overall control is such that fuel flow to the burner (18) is a function of the position of speed setting lever 94, compressor speed, pressure differential P c -P a  and outlet air temperature (T R ), and atmospheric air pressure P a  or altitude.
