Title: Fluid-operated well-drilling mechanism
IPC: E21B4/14
Filed: 1958-01-06
Abstract: 819,160. Liquid-pressure engines. GULF RESEARCH & DEVELOPMENT CO. Jan. 6, 1958 [May 16, 1957], No. 398/58. Class 69 (2). [Also in Group XXI] A liquid-operated percussive drilling mechanism comprises a tubular housing 3, 10, an inverted cup 55 mounted in the housing above a constriction 8, a bit 25 slidable in the housing below the constriction, a hammer 33 within the housing and having sliding contact with the constriction, and a valve 44 slidable within the cup and having a larger diameter than that of the constriction. The drill, comprising a drill string from which the mechanism depends, is run into the hole with the valve, hammer and bit in their lowermost positions relative to the housing so that drilling liquid supplied through openings 7 passes through holes 53 to discharge through the central passages in the valve, hammer and bit. The drill is lowered until the bit touches the bottom of the hole, the mechanism taking up the positions shown in Fig. 5. As the holes 53 are blocked, the liquid pressure raises the valve and hammer until the valve head 48 is about to enter the cup (Fig. 6). From this position the valve accelerates upwardly and the seal 47 between the valve and hammer is broken. The valve and hammer rise to their uppermost positions (Fig. 8) and then fall to the positions shown in Fig. 5 in readiness for a further operational cycle of the mechanism. Springs (not shown) may be respectively mounted in the cup and below the constriction to assist the downward movement of the valve and hammer, and a shoulder may be provided on the hammer neck 36 to cooperate with the constriction to prevent the hammer jamming in its uppermost position. The juncture between bit and housing is formed to transmit torque so that the bit may also be rotated.

Title: Method of and machine for cutting multiple screw threads
IPC: B23G1/02
Filed: 1946-01-05
Abstract: 640,141. Lathes. SOC. CRIDAN. Jan. 5, 1946, No. 479. Convention date, Jan. 10, 1945. [Class 83 (iii)] Relates to the screw-cutting lathes described in Specification 640,142 and consists in a method of and means for cutting multiple threads by a series of cuts in which a cut at each depth of feed is applied automatically in turn to all the threads before further cut is applied and the lathe stops at the end of a cycle. The saddle is traversed by a pitch cam 107 and returned by springs, the cam rotating once for each complete cut and return. The shaft 102 driving the cam is geared to the spindle 103 by a train such that the spindle makes the required number of whole revolutions plus a fraction of a revolution equal to the reciprocal of the number of starts. The mechanism is supported. by a subsaddle 101 adjustably positioned as described in Specification 640,142 and a two-part adjustable cam 112 rocks a lever 115 at the end of each traverse to reciprocate a bar 116 with a wedge end interposed between the end of a lever, controlled by a cut-applying eccentric 120, and one end of a lever 117 whose other end controls the movement of the cross slide. Advance of the wedge between the lever ends removes the cut and return of the wedge permits springs to restore it. The eccentric is geared by a quadrant 119 to a shaft carrying a ratchetwheel 1 driven by a pawl 3 carried by a lever 5 linked at 7 to the lever 115 and held by a detent 8. The pawl has a tail that rides on the edge of a notched disc 26 carried by the lever 5 and rotated step-by-step by a ratchet 28 and pawl 29, mounted on a fixed pivot. A detent 31 is mounted on the lever 5. The ratchet 28 may have twelve teeth and is rotated one tooth each time the cam 112 rocks the lever 115 to restore the cut. If a four start thread is to be cut, the notches 26a each corresponding to one tooth are separated by lobes 26b corresponding to three teeth. Whilst the pawl 3 rides on the lobe it is held away from the ratchet 1 so that cut is only applied after a chasing traverse on each thread. A peg 14 is set in a hole in a disc 13 such that when all the threads are cut to depth the peg engages a lever 15 on a rock-shaft 16 having arms 17a and 19a that trip the pawl 3 and detent 8 allowing a spring to return the eccentric to its initial position. The rock-shaft is also geared to means for operating the main driving clutch so that the entire lathe is stopped. A rockshaft 21 fitted with a hand lever 22 provides manual control for the pawl 3 and detent 8. The lever 19 is driven from the shaft 16 through a clutch so that it may be rocked without moving the lever 17 whilst movement of the lever 17 rocks the lever 19 also. When the shaft 21 is rocked clockwise, Fig. 1, an arm 23 engages an arm 19b on the lever 19 to trip the pawl 3 and suspend feed, but on rotation in the opposite direction an arm 24 acts through a double-armed lever 25 to engage the arm 17b of the lever 17 and trip both the pawl 3 and the detent 8, stopping and resetting the feed mechanism.

Abstract: 1,166,311. Getters. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 5 Jan., 1967 [8 Jan., 1966], No. 761/67. Heading H1D. A getter for use in an electric discharge tube, e.g. a cathode ray tube or a travelling wave tube, initially comprises a mixture of zirconium hydride and tungsten powder and is manufactured by a process which includes the steps of reducing the hydride to metallic zirconium which is subsequently superficially oxidized by exposing it to an oxygen atmosphere at 10<SP>-4</SP> Torr pressure. The zirconium hydride and tungsten powder mixture is first heated, e.g. to 850-900 C., in a separate vacuum space to reduce the hydride, the hydrogen evolved being pumped away, then the resulting mixture is subjected e.g. at room temperature to a 10<SP>-4</SP> Torr oxygen atmosphere e.g. for a few hours, so that the grains of zirconium are superficially oxidized. The mixture is then mounted in a discharge tube which is degassed and pumped down and then the getter is heated for about 30 seconds to 800-1000 C., either before or after sealing the tube, so that the oxygen diffuses into the grains of zirconium and the getter is activated. A specific example is given.

Abstract: 400,155. Synchronous movements. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Butler, H. R. ; 278, Rutledge Avenue, East Orange, New Jersey, U.S.A.) Jan. 11, 1932, No. 796. Void [Abridged as open to inspection under Sect. 91 of the Acts, Jan. 11, 1932]. [Class 40 (iii).] In a radio picture-receiving apparatus having a rotatable light sensitive member 3 or a rotating light source driven by a motor 10 which is controlled by a mechanical or other governor 14, a predetermined phase relationship between the rotatable member and the incoming synchronizing signals is maintained by automatically varying the setting of the governor by means responsive to any departure from the desired phase relationship. In the arrangement shown the motor 10 is adapted to drive a rotatable and axially fed light-sensitive drum 3, the speed of the motor being regulated by a brake-disc 15 forming part of the governor and a brake-block 16, or by a tuning-fork or oscillator, while the incoming synchronizing signals periodically energize a correcting relay 25. Co-operating with the latter is an insulating cylinder 18 mounted on the drum shaft 5 and carrying two spaced contacts 19, 20 designed to coact with three brushes 21, 22, 23. If the correct phase relationship is being maintained, then, at the time the relay 25 is energized by an incoming signal, the brushes 21, 22, 23 will make idle contact with the insulating portion of the cylinder 18 between the contacts 19, 20. If, however, the phase of the cylinder 18 has been advanced or retarded, one pair of brushes 21, 22 or 22, 23 will complete a circuit via the contact 19 or 20, energizing alternative relays 28, 27, which in turn control the movements of alternative pawls 32 'acting on opposite sides of a toothed wheel 33, whereby the position of the brake-block 16 is adjusted in the corrective direction. The pawls 32 are normally maintained out of contact with the teeth of the wheel 33. In order to lengthen the duration of the current that actuates the relays 27, 28. capacities 38, 37 are introduced in parallel therewith.
