Title: Fluid meter register drive mechanism
IPC: G01F15/02
Filed: 1952-10-06
Abstract: 728,766. Epicyclic ratchet gearing. ROCKWELL MANUFACTURING CO. Oct. 6, 1952 [lVov. 28, 1951], No. 24952/52. Class 80 (2). [Also in Groups XIX and XXIX] In a fluid meter register drive mechanism, a planet carrier 26 is mounted on an input shaft 22 coaxial with an output shaft 54 carrying a sun-wheel 68 and the planetary pinions 50 are connected by one-way clutches 48 to levers 46 carrying rollers 106 adapted to co-operate with stationary cams 100 to impress a plurality of equal increments of rotation on the output shaft for each revolution of the input shaft. The rollers 106 are normally urged by springs 70 toward the axis of the device, but their displacement is limited by stops 74 on the carrier 26 abutting portions 76 of the levers. The input shaft is driven in a clockwise direction, Fig. 2. Each time a roller 106 engages a cam 100 the associated lever 46 pivots anticlockwise and drives, through its one-way clutch 48, the planet pinion 50 in the same direction. An additional angular movement is thus transmitted to the sun-wheel 68 causing the output shaft to advance on the input. After passing the cam, the lever 46, is pivoted back against its stop by the spring, the one-way clutch being inoperative and clockwise rotation of the planet pinion 50 about its axis is prevented as one or more of the remaining one-way clutches will be operative. With three cams, 100 and four levers 46 there will be twelve increments of angular movement impressed on the output shaft for each evolution of the input shaft. The cams 100 are radially adjustable simultaneously, to vary the drive ratio, by segments 96, Fig. 3, on which they are mounted and which co-operate with a gear-wheel 126 rotatable by a screw-and-nut mechanism 138, 134. The transmission ratio has a minimum value of one to one when the cams 100 are moved inwardly out of the path of the rollers. Members 102 attached to the cams 100 prevent damage if the mechanism is reversed. U.S.A. Specifications 2,216,016 and 2,438,935 are referred to.

Title: Improvements in and relating to electric gas blast switches
IPC: H01H33/91
Filed: 1939-08-31
Abstract: 532,477. Liquid-blast switches. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 31,1939, No. 25009. Convention date, Aug. 31,1938. [Class 38 (v)] In a switch of the kind in which at least one contact is movably mounted in an extinguishing- head and in the open position an isolating gap exists between the head and the other contact, or a similar head, as described in Specification. 483,996, the extinguishing-blast is produced by the relative movement of the contact or of a nozzle surrounding the contact, with respect to the head during the opening movement, so adapting the switch to breaking relatively small amounts of power. In Fig. 3, vertical insulators 13, 17 carry a roller contact 15 and a head 14 which comprises, Fig. 1, a contact 7 on a tube 5 on a piston 2, which is urged outwards in cylinder 1 by a spring 3 when the arms are rotated in the direction of the arrows of Fig. 3. The piston 2 thus forces air from chamber 18 through apertures 19 into the tube 5 and insulating nozzle 11, the back pressure eventually slowing the piston until it and the contact are stopped by the rubbing contact 8. The nozzle 9 is forced further outwards and the roller 15 separates from the head, whereupon the blast issues from the nozzle and quenches the arc. The nozzle 9 and contact 7 of Fig. 4 are both urged outwards, air being forced from space 18 through holes 19 into the space behind the nozzle and being released when the contact 7 is arrested. This head may cooperate with a roller 15 in the rotary switch of Fig. 3, or the two heads shown in Fig. 1 or 4 may be arranged to meet " head-on." The airflow can be increased by lining the nozzle with arc-quenching gas-evolving material.

Title: Circuit for detecting periodic variations superimposed upon a train of otherwise randomly distributed pulses
Inventor: WALKER DAVID ARTHUR
IPC: G01P3/489
Filed: 1967-06-01
Abstract: 1,118,474. Frequency discriminators. ROLLS-ROYCE Ltd. 1 June, 1967, No. 25307/67. Heading H3A. [Also in Division G1] Periodic variations in the pulse rate of a pulse train having a constant average frequency are detected by comparing the pulse rate with that of a train of clock pulses, to produce an output signal if consecutively the clock pulse rate exceeds the varying pulse rate and the varying pulse rate exceeds the clock pulse rate. Assume initially bi-stable circuits 60, 110 are in their " 1 " state, then the next clock pulse switches bi-stable circuit 60 to its " 0 " state. The next pulse on input 32 switches bi-stable circuit 60 back to its " 1 " state, and is also fed via AND gate 54 to one input 68 of AND gate 70. The other input 66 still receives a " 0 " due to delay 64, so that no signal is passed to counter 102. Subsequent pulses at 32 have no effect on bistable circuit 60, but they pass through AND gates 54, 70 and are counted in counter 102 until the next clock pulse switches bi-stable circuit 60 into its " 0 " state and closes gate 70. The above procedure is repeated until the counter 102 reaches a predetermined count and switches bi-stable circuit 110 to its " 0 " state, resetting the counter. Gate 80 is now enabled, and the roles of the clock pulses and the other pulses are reversed, with the counter counting the number of clock pulses occurring between pulses at input 32. The input signal applied to 32 is derived from a scintillation counter positioned near a rotary bearing which includes a radioactive roller, Fig. 1 (not shown).

Title: Improvements in and relating to the casting of metals
Inventor: SAVAGE JOHN
IPC: B22D11/053
Filed: 1951-10-31
Abstract: 715,282. Continuous casting. BRITISH IRON & STEEL RESEARCH ASSOCIATION. Oct. 31, 1952 [Oct. 31, 1951], No. 25463/51. Class 83 (1). In the continuous casting of metal, withdrawal of the cast billet from the mould is discontinued when the resistance to relative movement of the metal and mould rises above a limiting value, and resumed only when such resistance falls below that limiting value. A water-jacketed mould 6 is supported on compression springs 11. If the partially-solidified billet 8 sticks to the mould, resistance to withdrawal by the pinch rolls 9 increases and the mould is pulled down with the billet so that there is no relative movement between the billet and the mould, i.e. withdrawal ceases. When adherence of the billet to the mould decreases due to its cooling, and the restoring force of the spring increases due to their compression, the springs return the mould upwardly. The amplitude of movement of the mould depends inter alia upon the mould characteristics, nature of metal being cast and the strength of the springs 11 which is so chosen that the maximum restoring force exerted on the mould will be below that which would cause rupture of the casting to occur. When 'casting 3-inch diameter steel billets in a copper water-cooled mould at speeds up to 3 feet per minute, the movement of the mould was limited by stops 13 to a maximum of 2 inches, the springs 11 exerting a maximum restoring force of 200 lbs. In modifications, the mould is suspended from tension springs, or is counterweighted, or the drive to the pinch rolls is through a slipping or yielding clutch.
