Title: Improvements in presses, punches or the like
IPC: F16D67/06
Filed: 1951-03-07
Abstract: 688,435. Operating clutches. MASCHINENFABRIK WEINGARTEN AKT.-GES. March 7, 1951 [March 22, 1950; March 22, 1950], No. 5515/51. Class 80 (ii). In a clutch for a power press, punch or like machine, the driving flywheel 5 is arranged between a conical friction surface of a collar 11 adjustably secured to the machine shaft 1 and a flat friction surface of a sleeve 3 which is mounted on quick-pitch threads 2 on the shaft 1 and which constantly abuts, through a thrust bearing 10, against a non-rotating disc 8 between which and a second non-rotating disc 7 are arranged pre-stressed springs 6, the disc 7 co-operating with a conical friction surface of a collar 9 secured to the shaft 1. With the sleeve 3 arrested by a pawl 15 engaging a tooth 3a on the sleeve, the latter is displaced away from the flywheel to disengage the clutch and compress the springs 6, applying the brake disc 7 strongly against the shaft collar 9. If, however, the pawl is tilted to free the sleeve 3, the latter is displaced on the threads 2 by the springs 6 towards the flywheel to engage the clutch, the disc 7 remaining in light frictional contact with the collar 9 and the friction effect of the flywheel on the collar 11. being greater than that on the sleeve 3. The pawl carrier 16 is mounted on a rubber buffer 17. The pawl 15 is normally held in the path of the tooth 3a by a spring 22 and is tilted out of the path when an electromagnet 18 .is energised to attract a pivoted armature having a projection 19 engaging a bar 21 pivoted to the pawl. A cam 26 on the sleeve 3 coacts with an arm 20 to move the bar 21 positively back towards the end of the revolution so that, if the magnet has been de-energised, the clutch is disengaged and the brake applied at the end of the revolution. By means of other teeth 36-3e, the clutch may be disengaged, on de-energisation of the magnet, at various stages during the downstroke of the press.

Title: Improvements in and relating to gas turbine power plant
IPC: F02C7/275
Filed: 1945-03-05
Abstract: 590,418. Gas turbine plant. BRITISH THOMSON-HOUSTON CO., Ltd. March 5, 1945, No. 5516. Convention date, March 7, 1944. [Class 110 (iii)] [Also in Groups XXIX and XXXVII] Relates to starting and control arrangements for a gas turbine plant comprising, for example, a compressor 3, a combustion chamber 2 and a turbine 2a. The burner 6 is supplied with fuel by a pump 21, the output of which can be returned to source by a valve 87 controlled by an emergency governor, or be bled by a valve 90 under atmospheric pressure control. The fuel passes through a starting and operating valve box 24. In starting, the circuit of a starting motor 8 is closed, by a relay switch 13, through a resistance 17 which is soon short-circuited by a delay action relay 18. During starting a sparking plug 7 is energized from a transformer 16 and a fuel sufficient for running light passes through box 24. When the turbine begins to take up power, the ignition and starting motor circuit is broken and the supply of fuel adjusted by hand. The valve box 24, Fig. 2, comprises, in series, a stop-valve 50 and a regulating piston valve 34. Fuel, for idling, passes through a permanently open passage 47 in valve 34 which can be regulated by means of a pin-valve 48. When the turbine is running under power, the piston part of the valve 34 is moved beyond the end of the sleeve 27 and control is effected by the conical part of the valve body. The valves 34, 50, are operated by means of links, levers and cords from shafts 44 and 60 in a control box 15. The operating lever 70 is carried by a shaft 67 directly geared to shaft 44 and has a roller which engages a slot in a lever 63 on the shaft 60. When the lever 70 is moved to position A, a cam 75 closes the contacts 14 in the circuit of the relay 13 and the ignition and starting motor circuit is closed. Movement of lever 70 to position B causes the lever 63 to swing to its upper position and thereby open the stop-valve 50, the piston portion of the valve 34 still closing the end of the sleeve 27. When the plant is running under its own power, further movement of the lever 70 immediately releases the contacts 14, so shutting down the starting motor and the spark ignition, and regulates the supply of fuel by means of the conical body of valve 34. The rod 78 has a pivoted endpiece so that in the return of the control lever to its initial position, the cam 75 does not close the contacts 14. Specification 590,422 is referred to.

Filed: 1944-03-25
Abstract: 579,398. Latches. PARKER, T. H. March 25, 1944, No. 5568. [Class 44] Relates to latches of the kind in which the bolt is held by a detent in partly retracted position so that its bevelled end, by engagement with the striker plate, pushes the bolt inwards and so releases the detent to allow the bolt to shoot fully into engagement with the keeper, the invention being particularly concerned with mortice locks of small dimensions suitable for drawers, doors of cabinets, &c. The bolt f shot by spring g is retracted by a follower b<1> on the spindle n carrying handle o, the follower acting on the tail cross-bar of a runner plate b slidably guided by the casing i. Member b has inward projections p engaging lateral projection q on the bolt, and is biased to normal position by a spring h mounted on a pin k secured to the rear end of the casing. The bolt is bifurcated as shown to provide rearwardlyextending limbs which overlap the cross-bar of runner b, the overlapping parts being cut away to reduce the overall thickness, the cut-away portions of the cross-bar providing recesses leaving a central part v not cut away, the shoulders of which serve to guide the tail end of the bolt. The outer ends of the recesses provide inclined shoulders r. The bolt limbs are formed with undercut shoulders e. The detent comprises a spring member c anchored to the rear end of the casing and having inwardly-hooked ends d which are biased outwards away from the bolt, and towards the side members of runner b, as shown. When member b is moved to the left to retract the bolt the shoulders r exert cam action on correspondingly inclined portions of spring c to stress the ends d inwards so that they snap into engagement with the shoulders e to hold the bolt in partly-retracted position. When the bolt is pushed inwards, the hooked ends disengage and spring outwards to the boltreleasing position shown. In place of the handle the latch may be operated by a key which fits into a hole in a shaft which turns the follower b<1> but does not project beyond the face-plate o<1>.

Title: Improved phase-responsive electric circuit
IPC: G01P1/04
Filed: 1961-02-15
Abstract: 909,123. Phase-sensitive circuits. GENERAL MOTORS CORPORATION. Feb. 15, 1961 [May 23, 1960], No. 5613/61. Class 38 (4). In a phase-sensitive circuit a reversible direct voltage between lines 34, 38 is derived from a resistor 32 in series with rectifiers 40, 44 and transistors 48, 50, arranged as shown, supplied from a secondary 28 of a transformer 13 connected to an alternating current source 10. The base-emitter bias of the transistors is derived from an output winding 20 of an eddy-current or drag-cup tachogenerator 16 having an input winding 14 supplied through a capacitor 18 from the source 10. For one direction of rotation of a rotor 26 the voltage of the winding 20 is inphase with the voltage of the source and current flows during the first half-cycle through transistor 48 and rectifier 44 to the resistor 32. When the rotation of the rotor 26 is reversed the current then flows during the second half-cycle through rectifier 40 and transistor 50 to the resistor 32 so that the polarity of the voltage between lines 34, 38 is reversed. A diode 25 limits the reverse voltage across the transistors and resistors 66, 68 provide bias to the transistors and resistors 70, 72, 74 negative feedback so that the direct voltage is linear with respect to the amplitude of the alternating voltage from the tachogenerator 16.
