Title: Improvements in or relating to apparatus for determining corrections for a gun or the like mounted on a tilted platform
IPC: F41G3/10
Filed: 1938-07-25
Abstract: 577,788. Guns on inclined platforms. VICKERS-ARMSTRONGS, Ltd., and WATSON, J. P. July 25, 1938, No. 22057. [Class 92 (i)] Relates to apparatus for applying corrections in elevation and training for tilt of gun platform without levelling the platform. According to the invention, solid cam devices 23, 24, which receive a composite movement according to both elevating and training angles, impart lifts to correcting mechanisms X, Y which are functions of the elevating and training corrections necessary for a chosen maximum tilt (#), the actual tilt (T) being also set into the mechanisms so that the applied corrections are reduced in accordance with the rates T/#. In the apparatus shown, the shafts 28, 49 are driven from the normal gun elevating and training gears respectively, the corrections being introduced by the planetary members of differential gears 29, 50. The shafts 28, 49 are then operated until the pointers 32, 52 register with dials set to the true angles of elevation and training. The maximum tilt (#) is set into the apparatus by adjusting the gun until a spirit level bubble 1 is central and then turning hand wheel 8 until a spirit level bubble 2, moving at right angles to the first, is centralised by adjustment of a carrier 3 about an axis 4 parallel to the gun trunnions. The hand wheel 8 imparts movement to a slide 10 slots in which engage over pins 15, 16 on sleeves 17, 18 carried by the pivoted followers 19, 20 of the solid cams 23, 24. The pins also engage slotted racks 35, 56 which actuate the planetary pinions of the differential gears. The cams are translated in accordance with elevation angles by a screw 27 and rotated in accordance with training angles by a shaft 39. When setting in the maximum tilt, the cams are rotated to a datum position by a handwheel 45 until a pointer 42 registers with a setting mark 43. The cams are designed to suit accurate formulae based on spherical trigonometry which are quoted in the Specification.

Title: A register for high frequency phase jitter
IPC: G06F5/08
Filed: 1959-06-26
Abstract: 925,400. Transistor pulse circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 26, 1959 [June 30, 1958], No. 22084/59. Class 40 (6). [Also in Group XIX] A shift register (see Fig. 5) for storing data received on input line 28 as a pulse (representing " 1 ") or no pulse (representing " 0 ") in each bit period, and in which shift pulses for the trigger stages 25, 26, 27 ... of the register are derived from the data pulses, has a pulse generator 38 generating a train of shift pulses following each input pulse, and a gate 36 opened by a mono-stable flip-flop 32 via trigger 35 after 1¢ bit periods have elapsed without receipt of an input pulse. Fig. 6 shows waveforms; the input pulses (a) may each occur anywhere in their respective bit periods and as shown represent the binary number 1111001. Line (b) shows the state of trigger 25, which is set by the " 1 " pulses and reset by the same pulses delayed by unit 44 and passed by " or " gate 45; this resetting shifts data in the register in the normal way. If 1¢ bit periods elapse without an input pulse, 32 (the " recovery " waveform of which is shown at (c)) produces an output pulse 95 (e) which is passed to the shift line 29 (see 89, line (1)) and also switches 35 to open gate 36. The pulse generator 38 includes a ringing circuit tuned to produce a half-cycle in each pulse period and set in operation (line (g)) by each input pulse; this signal differentiated (h) and squared (i) is used to produce shift pulses (j) at the cross-over points of the squared signal. The first of these to be gated via 36 is 81 appearing on the shift line as 90; subsequently (in the absence of a " 1 " bit) they would appear at successive bit intervals. Fig. 7 shows unit 38 in which 52, 53 constitute the ringing circuit referred to above, which is normally undamped but damped and re-phased by conduction of T 1  caused by an input pulse. Differentiation is effected by 57, 60 and squaring by T 3 , T 4 . Circuit 61 produces an output pulse at each excursion of the input signal, a ringing circuit 91, 92 causing a positive pulse from T 4  (which has no effect since T 5  is cut off) to be followed by a negative excursion which instantaneously produces a positive signal out put before the feed-back through 94 is effective. Negative pulses produce a similar output with out ringing, in each case conduction of T 5  damps out ringing after the single output pulse has appeared.

Abstract: 687,600. Voltage, frequency and phase comparison. STANDARD TELEPHONES & CABLES, Ltd. Sept. 15, 1950 [Dec. 28, 1949], No. 22727/50. Class 37. An A.C. circuit for comparing a reference signal with a test signal comprises a balance network having the control circuits of two gas-filled discharge tubes in opposite branches, one of the tubes controlling action consequent upon the reference and test signals having a predetermined relationship, e.g. equality. As shown in Fig. 5, the standard alternating potential Sc is applied to a transformer Tr3 and the test alternating potential Ss is applied between e and the centre-tap m of the secondary of transformer Tr3, so that in one branch Tr1, e.g. the potentials are opposed and in the other branch Tr2 the potentials are additive. When Sc-Sc is of insufficient amplitude, tube T1 extinguishes to allow tube T3 to ignite and actuate relay Sr. This circuit can be used to compare A.C. signals that differ in amplitude, frequency, or phase. For amplitude differences to be detected, the frequency and phase are identical so that T1 is extinguished only when the amplitudes are substantially equal. For phase differences to be detected, the signals have the same amplitude and frequency, so that only when the signals are substantially in phase is the tube Tl extinguished. For frequency differences to be detected, the beat frequency is developed and when it is too low to maintain continuous conduction of lamp T1 (at about 600 c/s.) the lamp T3 cannot ignite. In Fig. 6, the test signal Ss is applied to a transformer Tr2 whose secondary is connected between the centre-tap of the secondary of transformer Tr1 and the point in 2; the tubes T1, T2 are shunted by high resistances R6, R7 to maintain balance when one is non-conducting. In Fig. 7, the reference and test signals Sc, Ss are applied in opposition to transformer Tr1 whose primary is centre-tapped to earth through the primary of transformer Tr2, so that transformer Tr1 is energized by Sc-Ss, and transformer Tr2 by Sc+Ss. In Fig. 8, Sc and Ss are applied to transformer Tr1 whose two primary windings are connected to primary windings of transformer Tr2 so that Sc and Ss are opposed in one transformer and additive in the other. A final embodiment is shown in Fig. 9, where the signals Sc, Ss are applied to separate transformers whose secondary windings are connected so as to provide Sc+Ss in the circuit of T2 and Sc-Ss in the circuit of T1. The invention is applicable to positioning a rotary switch, the signal Sc being selected in accordance with the desired position of the switch, and the signal Ss being provided from a brush swept by the switch over contacts energized with different potentials, frequencies or phases. Specifications 565,785 and 631,156, [both in Group XXXIX], are referred to.
