Title: Means for controlling the movement of trolleys or other bodies along a predetermined path or track
Inventor: BURROWS ARTHUR THOMAS CHARLES
IPC: B61L3/04
Filed: 1962-02-28
Abstract: 1,056,261. Automatic vehicle control. GEO. W. KING Ltd. May 28, 1963 [Feb. 28, 1962], No. 42486/61. Heading B7N. In an arrangement for controlling the movement of a trolley confined to a predetermined track so that it halts at a selected one of a number of stations, projectable and/or fixed striker elements at the selected station cooperate with a ramp-operated variable resistance and switch elements on the trolley to initially brake and then halt the vehicle at the station. The vehicle is driven and controlled by electric motor 15 with associated electromagnetic brakes 16, 19, drive coupling 17. brake coupling 20 and travel motion gear-box 19. The arrangement is described with reference to three stopping stations one of which is selected by operation of one of the buttons PB1-PB3 which energizes the required solenoid to raise the projectable striker at the selected station to its operative position. Pushbutton PB4 is a start button which initiates forward movement of the vehicle towards the stations. Assuming the second station is selected, as the vehicle passes the first station a fixed striker at the station depresses a ramp on the vehicle coupled to a variable resistance 21 in the circuit to drive coupling 17, however, since the projectable striker at this station is not operated, limit switches L1S4 in the forward drive circuit and L/S8 and L/S9 controlling solenoid R5 with contact R5A in the brake coupling circuit will not be operated and limit switches L/S10 and L/S11 are operated in turn by the striker when retracted to energize and de-energize solenoid R6 a contact of which shuts out the variable resistance to maintain full excitation to the drive coupling during the period the vehicle passes the station. As the vehicle approaches the second (selected) station limit switch L/S8 is operated by the projecting striker, operating solenoid R5 whereby current is supplied via contact R5A to the brake coupling 20 to retard the vehicle and ramp 25 is depressed to vary resistance 21 and partially de-energize the driving coupling 17. Just before the required stopping point is reached limit switch L/S9 is operated by the projecting striker to de-energize solenoid R5, the brakes are released and the vehicle proceeds with low drive until it reaches the stop position at which L/S4 is operated to cutoff the drive and apply the electromagnetic brakes 16 and 18. At the completion of the loading or unloading operation at the station a limit switch, in this case L/S ST2 is opened, releasing the associated solenoid R2. If the vehicle has only to stop at one station the release of the solenoid completes at R2B the reverse energizing circuit of the vehicle and it returns to the despatching station, further limit switches being operated by strikers at the despatching station to bring the vehicle to a halt.

Title: Improvements in voltage regulating transformers
Inventor: THOMAS ROBERT GEORGE
IPC: H01H9/00
Filed: 1960-12-09
Abstract: 942,828. Electric transformers. FOSTER TRANSFORMERS Ltd., R. E. JENNINGS, and I. R. M. STEWART. Dec. 11, 1961 [Dec. 9, 1960], No. 42494/60. Addition to 775,742. Heading H1T. In a transformer tap-changing system as described in the parent Specification and Specification 775,741, having the coarse tapchanging switch mechanically linked to a fine regulating switch system the toroidal transformer incorporated in the fine regulating system has a winding bearing a number of sections (two) each having a contact moving over and directly engaging it to feed a winding of an auxiliary transformer the output of which is used in the coarse tap changing circuit to obtain smooth transitions between tapping steps. In the Fig. 1 arrangement the moving contacts 51, 52 which are mechanically linked to the tapping switches and to the rotary wiper switch 21, 22, 23, introduce variable voltages into the tapping switch circuits to output terminals O to obtain smooth transition from tapping step to the next. Additional voltages may be introduced into these circuits by oppositely connected windings of the main transformer (Fig. 4, not shown), or of an auxiliary transformer (Fig. 3, not shown). In another arrangement the winding sections 3, 4 (Fig. 5), of the toroidal transformer are separate and have contacts feeding primary windings 241, 242, 251, 252 of the auxiliary transformers T3, T4 additional impedances 36, 38 being provided so that the duty loading of the wiper switch 10 is reduced. This switch may be eliminated by arranging for the tapping contacts to operate step by step with the tapping contacts moving from one tapping stud to the next as the moving contacts on the toroidal transformer move from one section to the next (Fig. 6, not shown).

Title: Ammunition testing apparatus
IPC: F42B35/00
Filed: 1962-11-12
Abstract: 1,019,588. Ordnance for testing ammunition. MAUSER-WERKE A.G. Nov. 12, 1962 [Nov. 29, 1961], No. 42579/62. Heading F3C. A recoiling gun for measuring the maximum gas pressure produced by the propellant of the ammunition when firing comprises pressure meters 16, Figs. 1, 3 (not shown), located in a housing 14 surrounding and secured to the breech end of the barrel 10, the inner ends of the meters 16 being located in bores 18 in the wall of the barrel chamber and the arrangement being such that the centre of gravity of all the parts movable with the barrel on recoil including the housing 14 and pressure meters 16 is located on the axis of the barrel bore so that no transverse forces act on the barrel when firing to adversely affect the test of plotted hits which is carried out simultaneously. In addition a recoil braking device is provided in which the braking effect starts to act only after the projectile has left the barrel. Two recoil brakes 17 on one each side of the barrel 10 have recoil spindles 23 connected at their rear ends to a plate 13 rigid with the housing 14. Each spindle 23 carries a fixed collar 23a in front of which a uniform pressure brake 24 and behind which a compensating brake are arranged. The latter consists of a spiral spring 29 bearing at one end against a sleeve 28 in contact with the collar 23a and at the other end against the rear end wall of the brake housing 22. The brake 24 comprises a spring extending between two pairs of cones slidable on the brake spindle 23. When the barrel is in its forward position and the brake is inoperative, the spring 29 holds a slidable abutment sleeve 26 against an abutment in the housing 22. If the weapon is set at an angle of elevation then the weight of the barrel is compensated by the spring 29. If a shot is fired, the recoil acts on the brake spindles 23. Each moves backwards taking with it the brake 24 until the rear pair of cones strike the sleeve 26 which is pushed back until it reaches the rear shoulder 22a of the housing 22. The spindle then compresses the spring 29 and during this phase the projectile has reached the barrel muzzle. On leaving the barrel, the full recoil impulse becomes effective and the sleeve 26 now abuts against the abutment 22a and the rear pair of cones in contact with the sleeve 26 slide one within the other and exert a steeply increasing braking force on the spindle 23. This force is damped during the continued rearword movement to an extent that the recoil forces are fully absorbed by the further compression of the spring 29. The spring 29 then pushes the spindle 23 forward again, the brake 24 is no longer effective and the parts resume the position indicated in Fig. 6 (not shown). A safety device is provided which prevents the operation of the trigger (not shown) for firing unless the pressure meters are located in their bores.

Abstract: 1,182,013. Copy-milling. FRIEDRICH DECKEL PRAZISIONS MECHANIK & MASCHINENBAU. 19 Sept., 1967 [21 Sept., 1966], No. 42697/67. Heading B3K. A manually-controlled copy milling machine, Fig. 1, e.g. of the type having a pantograph 84 linking the tracer and cutter, is adapted for servo-assistance of the copying movements by means of a bearing arm 44, Figs. 1, 3, 4 extending from the tool carrier 36 and carrying servo control means 58, Figs. 1, 3 and 7, at an end portion thereof, the bearing arm 44 also supporting a pivoted lever 72, Fig. 4, through a further pivoted lever 68, Figs. 1, 3 and 4, which lever 72 at one end is connected rigidly to the tracer holder 80, Fig. 3, and at the other end carries a coupling pin 88, Fig. 7, which is rigidly attached to an input member 92 of the servo means 58. The tracer holder 80 has a coupling 82 for connection to the pantograph 84. Thus hand controlled movements of the tracer cause small pivotal or three dimensional movements of the lever 72 with corresponding input through the pin 88 and input member 92 to the servo means 58. For three dimensional copying the lever 72 is made vertically displaceable on its pivot. The servo means 58 preferably controls movements of the work-table 24 by means of hydraulic servomotors 16, 30, 32, Fig. 1, but may control feed of the tool carrier. If the work-table is servo controlled the tool support 36 is bolted up to machine column 10. If it is desired, e.g. for a finishing cut, to return to totally manually controlled copying the servo means 58 may be removed and a plug, Fig. 8, (not shown) attached in its place, this plug serving to connect the lever 72 rigidly and impivotably again to the bearing arm 44.

A valve 10, adapted for controlling flow through a well pipe 11, includes a rotary plug 19 which has a bore 20 extending therethrough, is disposed within an enlarged portion 16 of the pipe bore 15, and is journalled between a pair of opposed bearing plates (22, 23, Figs. 3 and 4, not shown), the plates being retained between pipe portions 12 and 13, receiving plug bearing shafts, (35, 36), and having bearing balls (26) disposed between them and the plug, the balls being contained within ball races (27, 29) formed partly in the plates and partly in the plug. Plug bearing shaft (36) extends through the pipe portion interconnector 14 and has attached to its free end a crank 38. An annular sleeve 50 is slidably mounted circumadjacent interconnector 14 and has formed therein a longitudinal slot 51 within which a main portion 38a of the crank is disposed, and a further transverse slot which provides cam surfaces 54, 55 and accommodates the crank small end 38b. Upon application of pressure, via line 60a. to a chamber 59 formed at one end of the sleeve 50, the latter moves downwardly and, through the crank 38, rotates the plug 19 to a position wherein its bore 20 is in alignment with bore 15. Closure of the valve may be achieved either solely by the removal of applied pressure in which case springs 67, acting on the other end of the sleeve, move the sleeve upwardly, or by the application of a second pressure, via line 66, to the said other end of the sleeve, i.e., to chamber 64. In two modifications (Figs. 6 and 7, not shown) the second pressure line 66 and its connector 66a are replaced by a piston contained within a cylinder and enclosing a compressible fluid, or by a bellows which is subject to ambient pressure, respectively. In a further modification, (Fig. 5, not shown), the valve includes two serially arranged plugs 19 actuated in a manner similar to that above, the actuation being substantially in synchronism.
