Title: Improvements in or relating to power operated hydraulic jacks
IPC: B66F7/26
Filed: 1960-10-13
Abstract: 910,542. Hydraulic jacks. CASTROL EQUIPMENT Ltd., and EARLY, K. C. Oct. 13, 1960, No. 35176/60. Class 78 (3). An hydraulic jack comprising a motor-driven pump for delivering fluid to the jack cylinder is characterized in that independent handoperated valves are provided for controlling the inlet and outlet of the jack cylinder, and the pump motor is of such a type that it can be stopped without harm by an overload when both valves are closed, whereby the jack may be locked hydraulically in any position regardless of failure of the pump motor. As shown, the piston 13 of a reciprocating compressed air motor 10, such as that described in Specification 718, 532 is connected to the pump piston 17. Downward movement of the piston 17 closes outlet ball valve 42 and sucks fluid from the reservoir 18 through pipe 38, ports 36, 35, ball valve 34 and pump inlet port 31 into the pump cylinder 16. If lever 52 is not operated to engage a plunger 50 to open a ball valve 43, upward movement of the piston 17 will cause the pressure in the pump cylinder to close ball valves 43 and 34 and the load on the compressed air motor will cause it to stop. When the valve 43 is opened by the lever 52, the fluid in the pump cylinder passes through valves 42, 43 and port 45 to the jack cylinder 22. When the lever 52 is released, pressure in the pump cylinder closes valve 43 and the pump stops again, the pressure in the jack cylinder 22 closing ball valves 59, 65 and preventing fluid from returning from the jack cylinder to the reservoir 18 through the jack cylinder outlet port 53 and passages 56, 61, 67. When hand lever 70 is operated to open ball valves 59, 65, fluid can flow back to the reservoir from the jack cylinder through a bore 39 and ram outlet port 53. The tubular piston-rod 24 is provided with an internally threaded nut portion 28 which adjustably supports a lifting pad 30. The jack cylinder is provided with a support flange 27 which may be secured to a plate 78, Fig. 4, mounted on legs 81 which are provided with wheels 85. Alternatively, the flange 27 may be secured to a wheeled platform 86 which runs on a carriage 89 provided with wheels 95 running on tracks 96 fixed to the sides of a pit 97.

Filed: 1971-07-27
Abstract: 1300899 Regenerative heat transfer system CHICAGO BRIDGE & IRON CO 27 July 1971 [23 Nov 1970] 35229/71 Heading F4K In a heat transfer system using as a heat transfer medium a particulate material which is alternately melted and reconstituted as a particulate solid, said material is utilized in conjunction with a circulating liquid (e.g. water) to effect the primary heat exchange function (e.g. the removal of heat from a steam condenser). Examples given of suitable matterials are butyl stearate, docosane, tricosane, cetyl alcohol, and industrial paraffin waxes. In Fig. 1 the circulating liquid comprises the coolant water of steam condenser 11, circulated by a pump 22 through the condenser coils 14, thence via conduit 15 to a spray head 17 located in a tower 16 where the water is cooled by contact with a falling stream of the particulate material. The cooled water collects in a reservoir 20 and is recirculated by the pump 22 through the condenser. The particulate material is melted by its contact with the water from spray head 17 and the melt is removed by a pump 25 and conduit 26 to a spray head 19 the liquid droplets from which are solidified again as they fall, by cooling air admitted to the tower at 27. The spray head 19 may discharge upwardly (Fig. 2). In Fig. 3, the particulate material (again formed by contact of liquid droplets with cooling air in the tower 45) is mixed at 47 with the circulating liquid to form a slurry, and as this is circulated through the condenser coils 42 (by pump 55) the particles in the slurry melt and collect as a floating layer of molten material in a reservoir 51 into which the slurry is discharged. Melt from the layer 53 is circulated by a pump 57 to spray heads 70 in the tower, and the falling droplets are solidified into particles by air entering the tower at 60. The particles collect at 44 from which they pass via line 46 to the point 47 at which the slurry is formed.

Abstract: 882,217. Magnetic recording apparatus. COURT, .J. B., and LONG, N. G. Feb. 5, 1960 [Nov. 7, 1958], No. 35776/58. Class 40 (2). A juke box record player is provided with means operative at the end of each record to actuate the playing of a passage from a magnetic record tape. At the end of a playing of a disc record, a microswitch MS1 is operated by the automatic trip mechanism to energize a relay R1 which becomes latched in the energized state by the contacts of a delatch relay R3. The R1 relay contacts establish drive of the tape by starting motor 25 and bringing a pressure roller 26 into the operative position by a solenoid S1. In parallel with relay R1 is a change-over relay R2 which changes over the input connections on the juke box amplifier 13 from the gramophone pick-up 12 to the output of the tape pre-amplifier 30. At the end of a period of tape record reproduction a shorting contact 50 on the tape operates relay R3 to release the relays R1, R2 to the disc-record reproducing positions. When the end of the tape is reached a contact strip 56 establishes a reversal of drive of the tape through the medium of a solenoid S2 which causes the motor 25 to be reversed so that the capstan 24 is reversed, the spool carrying assembly 20 moved over so that the spools 21, 22 are driven in opposite direction, and the connections to the input of the pre-amplifier 30 are changed over from the upper track reproducing head 41 to the lower track reproducing head 41.

Abstract: 967,526. Indicating and recording production. SIEMENS & HALSKE A. G. Sept. 20, 1962 [Sept. 21, 1961], No. 35787/62. Heading G1J. Apparatus for recording production progress and displaying the records comprises a series of indicator cards K1 to K20, one for each work location the production progress of which is to be recorded, and a recording head Sch K arranged to record production progress on the cards when successively connected to their associated work locations by a step-by-step switch Stu driven in synchronism with the recording-apparatus. The cards are arranged to overlap and form a panel in a framework R, on which rollers run to guide a carriage Sch V for the head Sch K. The carriage Sch V is linked by a catch to a chain Ke driven by a motor AM and traverses the cards from bottom to top till released from the chain drive by the catch and allowed to fall to the bottom, being braked by damping means. Meanwhile a synchronous motor Sy drives the head Sch K horizontally by means of a toothed-rack Zst at a lower speed. The chain Ke also drives the arm KA of switch Stu whose 100 contacts 1<1>, 1<2>.... 20<5> are connected to switches Vsch1<1>, Vsch<2>,....Vsch20<5>, five at each location, one for each of five different machines, each switch being controlled by its corresponding machine to close only when the machine is operating. If one of these machine operated switches is closed when selected by switch Stu a generator JG sends a pulse to head Sch K causing a short stroke to be printed on the card appropriate to the location of the machine and in the one of five rows on the card appropriate to the particular machine. The switch Stu may be replaced by two switches having five and twenty contacts respectively and the five contact switch may be replaced by an electromagnetic printer in the head Sch K with five symbols used successively for the five machines at each station. The cards could be stacked round a drum.
Patent GB-494062-A (GB)
Title: Improvements in or relating to locking devices for elevator doors
IPC: E05B65/00
Filed: 1937-12-29
Abstract: 494,062. Locking lift gates. MAHLKE, W. Dec. 29, 1937, No. 35954. Convention date, June 12. [Class 78 (iii)] In well-door locking-appliances, the turning of the knob on the lock to withdraw the bolt, is only effective when the cage is standing at the floor, while silent working is ensured by arranging that the cage remains clear of the locking-appliances when passing floors at which it is not desired to stop. A two-dimension break of the operating circuit for the winding- gear also is made by the unlocking and the opening of the door. The contact roller o, Figs. 3 and 8, which normally hangs clear of the contact bars l on the cage, is carried by an arm h pivoted to the locking-bar r at m. Rotation of the member a by the attendant from the inside, or by an intending passenger from the outside, moves a member d axially to operate a bar s to swing the lever h. This has'no effect on the lock unless the cage is standing at the floor, in which case the roller o abuts against the bar l and forms a fulcrum about which the lever then moves to withdraw the locking-bar r from its socket to unlock the door. The bar has an upstanding contactcarrying arm at one end so that its movement causes the sets of contacts i to be displaced laterally to break the winding circuit. The unlocked door is then opened, which movement causes a slider g to be depressed by a cam groove on the housing carrying the bolt socket. This gives the displaced contacts i a further displacement in a vertical direction to allow of which they are mounted slidably on the arm carried by the bar. Contact is re-established in the same sequence as the door is re-closed and locked. The slider g in its lowered position also moves in front of the retracted bar r and retains it in the unlocked position. On closing the door the member g is raised to unlock the bar, and the spring f first swings the lever h counterclockwise and thus slides the bar r inwards to lock the door and then swings it clockwise to restore the members s and d to their original positions.

Abstract: 427,907. Vehicle spring-suspensions. ROESCH, G., and TALBOT, Ltd., C., Barlby Road, Ladbroke Grove, London. Dec. 21, 1933, No. 36024. [Class 108 (ii)] [See also Group XXXI] In a vehicle-suspension system of the kind in which each wheel is independently mounted upon a pivoted polygonal linkage, the pivotal movement of one or more of the links of which is resisted by a torsion member, such as a metal rod, tube, or helical spring, the linkage is disposed transversely and the torsion member longitudinally of the chassis, the torsion member being connected at one end to one of the links and at the other end to the chassis. As shown on the left-hand sides of Figs. 1, 2, the stub-axle 13 of a non-driven road-wheel 12 is supported by a member 14 connected by links 15, 16 to a bracket 11 fixed to the chassis. A lug 20, Fig. 2, fixed on the link 15 engages a non-circular portion of a torsion tube 17, the other non-circular end of which is fixed to a chassis member 19 so that movement of the link 15 twists the tube 17. Each link pivot comprises a bolt 22 passing through the forked end of one link and through a rubber bush 23 inserted in a sleeve in an adjacent link. The rubber bushes damp out vibrations and also act as torsion members. A second torsion tube 24 may be connected between the link 16 and chassis. In a modification the two links connect the bracket 11 to an axle-plate on a rear-wheel. In a further modification shown on the right hand side of Figs. 1, 2, the member 14 is omitted and spherical heads 25, 26 on the links 15, 16 engage spherical bearings on the stub-axle 13. In the construction shown in Figs. 3, 4, the vehicle front-wheels are engine-driven through half-shafts 29 and universal joints 30, 31, 32, 33, and are connected to the chassis by the casings of the half-shafts and by links 34 pivoted to lugs 37 on the chassis, the links having spherical ends 35 engaging spherical seatings 36 fixed to a cage surrounding the joints 31, 33. The torsion member comprises a helical spring 39 fixed at one end by a lug 41 to the link 34 and secured at its other end to the chassis and enclosed by telescoping cylinders. The pivot between each link 34 and lug 37 may incorporate a rubber bush 23, as shown in the left-hand sides of Figs. 3, 4, or a shock-absorber 44, as shown in the righthand sides of Figs. 3, 4, of the type having friction interengaging washers. In a further construction the rear-wheels are driven through half-shafts and universal joints, and the pivots of each link incorporate friction shockabsorbers.
