Filed: 1966-09-01
Abstract: 1,179,695. Releasable fastenings. G. & S. ALLGOOD Ltd. 29 Nov., 1967 [15 Sept., 1966], No. 39052/66. Heading E2A. A locking device comprises a latch spindle 4 formed in two axially distinct portions coupled one to the other and each carrying a respective handle 8, 19, the handle 8 carried on one of said portions of the spindle being movable axially within limits thereon but fastened rotationally thereto, the two portions of the spindle being axially adjustable one with respect to the other to permit precise axial positioning of the spindle and the handle on the other portion of the spindle preventing axial movement of the spindle in the direction of the first-mentioned handle, a faceplate for securing stationarily on a door, and tenon 15 and recess 16 locking means provided one by the first-mentioned handle and one by the faceplate at a radial spacing from the axis of rotation of the spindle, said tenon and recess being engaged and disengaged by axial movement of the handle 8 with respect to the faceplate. In the construction shown the face plate is the end wall of a recessed area of a nose plate 13 the spindle 4 passes through a follower 3 of a latch mechanism and near the follower the spindle carries a strip 5 which can be tightened into a selected position of axial adjustment by a screw 6 engaged in a slot 7 in the strip 5 and threaded into the spindle. The inner end of the strip 5 abuts against the boss of the follower so that the position of the spindle relative to the follower is determined so that the tenon and recess can be disposed in their correct relative axial positions. The two portions of the spindle are connected together by a threaded stem which engages a threaded hole. The positioning of the tenon 15 and recess 16 are such that in the rest position of the handle 8 the tenon does not align with the recess but so that it can be aligned by very slight rotation of the handle out of the rest position. The handle is maintained in the rest position by the spring which biasses the follower 3. When the tenon is engaged with the recess the handle 19 which is on the outside of the door and connected to the spindle cannot be rotated to release the latchbolt. By suitable disposition the tenon and recess or another tenon and recess can be used to lock the latch bolt in withdrawn position.

Title: Improvements in or relating to cathode ray tube deflection circuits
IPC: H03K4/28
Filed: 1958-12-16
Abstract: 908,798. Sawtooth generator circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. Dec. 16, 1958 [Dec. 19, 1957], No. 40536/58. Class 40 (6). In a sawtooth current deflection circuit for the indicator tube of a radar receiver, in which the scanning period is only a small portion of the interval between radar pulses, the deflector coil is fed in push-pull by being connected between the anode of two tubes to which sawtooth control voltages are applied. A tapping on the coil is connected to the anode supply voltage via an inductor and to the anode of a normally conductive discharge tube which is provided with negative voltage feed back, a negative pulse being applied to its grid during the application of the sawtooth voltage to the push-pull pair of discharge tubes. In this way, even if the rest position of the cathode-ray tube beam lies off the display screen, the dissipation in the push-pull connected valves is considerably reduced. Fig. 1 shows a sawtooth current deflecting circuit of a radar indicator (not shown), in which tubes B1, B2 are fed from a sawtooth generator ZG synchronized by pulses applied at terminal K to feed in push-pull deflector coil S. A synchronizing pulse at terminal K renders sawtooth generator ZG operative to start the sweep period of the current flow in coil S. The synchronizing pulse also triggers mono-stable trigger circuit M to produce a high value negative pulse at the grid of tube B3 so that the tube would be cut off. However, this is prevented by the negative voltage feedback via circuit C, R1. The sum of the currents, through tubes B1 and B2 during the scanning period is equal to the sum of the standing current and the current through coil L cannot be varied instanteously, so that the current through tube B 3 must also vary continuously and immediately after the start of a scanning period, the total current must be about equal to their rest value in spite of the negative voltage applied to the grid of tube B3. Thus since the grid voltage of tube B3 must also initially remain constant the voltage drop which would be produced by the output of the trigger circuit M must be compensated for by a voltage rise at point A. Thus this voltage rise must be equal to R1/R2 times the variation of the output voltage of circuit M. During the scanning period the current through tube B3 falls so that the voltage at point A is maintained at high value. Because of the voltage increasing effect of coil L which compensates the voltage decrease at the anode of tube B2 by the inductance of the coil S, the anode voltage Vb can have a low value which is sufficient to supply the currents during the rest period. The recovery time of trigger M is about equal to the effective deflection time. During the rest period the current through coil L is again increased to the initial value under control of tube B3.
