Title: Improvements in electrical indicating and recording systems
IPC: G01R17/04
Filed: 1944-03-16
Abstract: 581,382. Electric indicating systems. KEINATH, G. March 16, 1944, No. 4944. Convention date, Dec. 24, 1942. [Class 40 (i)] A recording mechanism which is controlled in dependence upon two variable quantities employs two Wheatstone bridges in which the resistance arms 211, 221 are varied in accordance with the two quantities. The contact arm 214 of the potentiometer 213 in the first bridge is rotated continuously with the recording drum 245 so that a point of balance is reached every revolution, thus operating relay 215 to discharge condenser 283. The contact member 224 of the potentiometer 223 in the second bridge is driven by a step-by-step motor 241 which is operated by discharge of condenser 283 when both relays 215, 225 are operated, that is when both bridges are balanced, a mark being made on the recording sheet at the same time. The voltage across resistance 221 is rising continuously so that when a point is reached where the bridge is balanced relay 225 is operated and the contact member 224 driven on one step by motor 241, the bridge thus becoming unbalanced again. Time marks are made on the recording sheet by a stylus 264 moved in proportion to time by motor 261. In Fig. 5 (not shown), a rotary reversing switch is included in the circuit of the step-by-step motor so that the motor may be reversed if the voltage across the corresponding variable element decreases. In this arrangement, the voltages across the variable elements are applied directly across the potentiometers, the relays being operated when a certain "threshold" voltage is applied to them. In another modification, Fig. 9 (not shown), the stylus is driven. by a motor which is stationary when the bridge is balanced, but when there is no balance a relay is operated so that the motor drives the contact arm of the potentiometer with the stylus into a position of balance.

Title: Improvements in or relating to pulse distortion detecting equipment
Inventor: DAY RICHARD ALLEN
IPC: H04L12/26
Filed: 1957-02-18
Abstract: 823,874. Testing-apparatus for telegraphy. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. Feb. 5, 1958 [Feb. 18, 1957], No. 5457/57. Class 40 (3). A pulse-distortion detecting device for an electrical signalling system in which the signals have one or the other of two values, and each value is nominally maintained for at least a fixed predetermined period, comprises timing means for comparing with a reference standard the period of time during which either value of the signals is maintained and giving an alarm if any signal period is of less duration than the reference standard. In the arrangement described for telegraph signals of marking and spacing elements, the mark-space and spacemark transistions trigger separate one-shot multivibrators having a relaxation time equal to the duration of the reference standard and if, during the period in which a vibrator operated by one of the transitions is passing an output, the opposite signal transition takes place, a signal is transmitted to the error-detecting circuit which may include a relay which becomes locked until a release action is taken. With signals exceeding the predetermined reference standard each multivibrator restores to its initial condition before the opposite transition takes place. In the diagrammatic arrange - ment, Fig. 1, the incoming signals are applied to a toggle V1 which has its sides A, B conducting in response to marks and spaces respectively. In response to a space or starting element a one-shot multivibrator V2 is operated to pass from its B side to a gate V4 a pulse of the reference standard duration, and the toggle V1, if changed to mark before the expiry of this duration, passes a pulse from its A side through the gate V4 to a pulse amplifier V6 which operates a gas-filled trigger V7 to actuate a relay RA controlling an alarm circuit. Similarly, the transition to mark operates V1 to produce a pulse from its A side to trigger one-shot multivibrator V3 and if the toggle V1 reverts to space before the expiry of the reference time duration, a pulse from its B side passes through the gate V5 to operate V6, V7 and the alarm relay RA. If the received pulses are of duration greater than the reference period, the pulse from the B side of vibrator V2 or V3 has been cut off from V4 or V5 before the opposite transition has taken place to provide the pulse from the A or B side respectively of the toggle V1. The detailed circuit arrangement corresponding to Fig. 1 has been described in connection with Fig. 2 (not shown).

Title: Improvements relating to sliding fastenings
IPC: E05C1/02
Filed: 1945-03-09
Abstract: 588,897. Sliding bolts. VINES, A. March 9, 1945, No. 5962. [Class 44] A fastening of the sliding bolt or catch type for doors or covers is made self-locking by a spring-pressed locking arm or detent engaging an aperture in the member carrying the bolt so that, while it has visible indication of the locked or unlocked position, it need have no protruding operating member. For example, in a fastening suitable for a cabinet, Fig. 1, a channel-shaped housing a has flanges along its upper and lower edges to be secured to a front plate c on the back surface of the door. A rectangular section bolt or catch e slides within the rear part of the housing a bearing against the edges of two internal plates, and co-operating with a rebate or catch plate g fixed to the back of the stationary member of the cabinet. A bent locking arm or detent i is pivoted to the bolt e at k and is urged forwards by a flat spring l so that when the bolt is shot the point of the detent will protrude through a hole m in the front plate c and into a hole n in the door ; thus the door will not be shaken free by vibration, and visible indication of the locked or unlocked position is provided. To unlock the door a loose rod or pin o is thrust through the holes m, n, and into a hope p in the bolt, thus pressing back the detent j; the pin o is now rocked to draw back the bolt e. To lock the door, the pin is again inserted and this time the bolt is pushed forwards ; the pin is then removed, and the detent j re-enters the holes m, n. In another construction, Fig. 3, the housing comprises a front plate with its edges bent back leaving recesses for flanges on the channel-section sliding bolt e ; the locking arm j curves out from the end of the bolt and is fixed to its back plate by a rivet t. The operating method is the same as before. Various modifications are suggested. The bolt may be formed with an inclined rear surface bearing on a correspondingly inclined surface on the back wall of the housing, so that the bolt when shot may bear firmly on the catch plate. The detent may be a rigid bolt slidable in a guide and urged forwards by a compression spring. Instead of using a loose operating pin, a lever may be left permanently in position, in which case the detent may be arranged to enter a hole independent of the operating lever. Two panels or other parts of a structure may be secured to enable loads to be transmitted from one part to the other. In the case of two panels with overlapping edges, a stud or pin secured in one may pass freely through the other, and have an annular groove on its protruding end. A sliding fastening of either of the previous constructions is mounted on the back of the first panel, and has forked or slotted bolt, so that when shot the prongs engage the slot in the stud and fix the two parts together.
