Title: Improvements in locks
IPC: E05B63/20
Filed: 1923-05-03
Abstract: 216,311. Lindberg, J. W. May 3, 1923. Latches, sliding; night-latches and like spring locks.-A follower-retracted spring-shot sliding latch is held in its intermediate or latching position by pin-and-slot engagement between it and its follower. Slamming of the door releases the follower to allow the bolt to shoot fully into lock-. ing position. The bolt comprises a head 1, shank 4 and nut or washer 5, perforated flanges 6, 7 on a plate 8 being engaged by the shank 4 to cause the plate to move with the bolt. Extensions 9 of the plate slide on a fixed rod 10 supported by lugs 11 on the casing and carrying the bolt-operating spring 12. The follower 13 is pivoted at P and has a spring 14 tending to throw it to the right. A pin 15 on the follower engages an L-shaped slot 16, 18 in the bolt-plate 8. Fig. 3 shows the bolt in its latching position, the pin 15 engaging a shoulder 21 at the corner of the L-shaped slot and preventing further outward movement of the bolt. In operating the bolt by the handle, the pin travels down the slot 18, withdrawing the bolt, and when the handle is released, the pin is again stopped when it reaches the shoulder 21. When the door is slammed, the bolt is pressed inwards, disengaging the shoulder 21 from the pin 15, allowing the spring 14 to flick the follower to the right, bringing the pin 15 into the large slot 16 and allowing the bolt to shoot out fully into the locking position. The bolt is withdrawn from this position by the follower, the pin 15 pressing on the shoulder 17 and snapping into the slot 18. When the bolt is in the fully shot position, an extension 26 on the follower engages behind the lug 25 on the bolt plate to prevent withdrawal by forcing. Lost motion occurs between the pin 15 and shoulder 17, in withdrawing the bolt, to ensure that the extension 26 is lifted clear of the lug 25 before the bolt begins to move inwards. A guide-pin 22 fixed to the casing co-operates with slots 23, 24 in the follower and bolt-plate respectively. A finger-operated stop 27 with a neck 29 pressed into an upper or lower side recess in a slot in the casing wall 3 by a spring 31, may be employed to hold the bolt in either of its extreme positions. The follower 13 may be operated from outside by a key.

Title: Improvements in or relating to apparatus for measuring relative motion between two bodies
Inventor: COATES LEONARD
IPC: H03K5/26
Filed: 1956-04-24
Abstract: 801,452. Photo-electric indicating arrangements. MULLARD RADIO VALVE CO., Ltd. April 24, 1956, No. 12507/56. Class 40 (3). [Also in Group XIX] The invention relates to an arrangement for determining the direction of motion, position, and distance travelled by a member capable of movement in two opposite directions. In this two trains of pulses are generated in response to any movement, the pulses being of the same frequency and the pulses of one train overlapping those in the other and having a displacement relative thereto whose sense depends on the direction of movement. For example, the number may carry a scale having alternate equal opaque sections D and transparent sections with alternately cut-off and pass light from a source S and lens L to two photo-cells P1 and P2. These are spaced along the direction of motion a distance equal to a quarter of the spacing between the centres of the sections D. The pulse output from cell P1, shaped if necessary to give a square waveform is differentiated at d to give an output train of alternate positive and negative short pulses. These are applied to a gate G.controlled by the output of cell P2 and the output of the gate circuit .will be either a train of negative-going pulses or a train of positive-going pulses according to the direction of motion. The output, pulses may be summed, taking account of sign, to give an indication of the position and distance travelled by the member. According to the present invention the accuracy of the arrangement is doubled by utilizing all the pulses, positive and negative, of the differentiated waveform to obtain the position and distance information. As described, this is done by feeding the pulses from the differentiator to a separator S1 which applies the positive pulses to gates Gland G3 and the negative pulses to gates G2 and G4. The square pulse train P2a from the cell P2 is used to control gates G2 and G3 and its invert, P2b, to control gates G1 and G4. Thus, according to the direction of motion, all the pulses appear on output line O1 or 02. The outputs may be applied so that each pulse, regardless of sign, from one output adds to the distance total and each pulse from the other output subtracts from it. If more convenient the output pulses may be made all of the same sign by incorporating invertors in, for example, gates G2 and G3. The initial pulses may also be generated electromagnetically.
