Abstract: 1518310 Latches WILMOT BREEDEN Ltd 17 Sept 1976 [17 Sept 1975] 38143/75 Heading E2A  A rotary bifurcated latch bolt 15 engages the shank of a striker pin 19 and is held in the fastening position by detent 16 which can be removed by control means. Both are pivoted by pins held between front and back plates 11, 12 of the latch casing, between which is also located a plastics moulding 22 (Fig. 2). This moulding contains a pathway for the entry of the striker pin, holes for the pivots two rubber blocks 21, 30 and a leaf-spring portion 25 bounding one side of the pathway. Part of block 21 has a bore to accommodate bolt pivot 13; the resilience of the block tends to push bolt 15 towards plate 12, contact is however prevented by plastics bushing 20. The striker pin on entry engages leaf-spring 25, which is buffered by block 21 and which, in combination with bolt 15 in the later stages of entry; provides a wedging action for better retention of the pin. The pin comprises part 28 of block 21 which provides an initial throw out on release. Pin 30 on pawl 16 is buffered by block 30.
Patent GB-1000265-A (GB)
Title: Beam-directing device for radiation transmitters, more particularly head lamps
IPC: B60Q1/18
Filed: 1962-10-09
Abstract: 1,000,265. Photo-electric control of radiation emitters. H.BAUMANNS. Oct. 9, 1962 [Oct. 9, 1961; Dec. 4,1961], No. 38153/62. Heading G1A. [Also in Division H4]. The direction of a beam of electromagnetic radiation emitted by a radiation transmitter e.g. a vehicle headlamp, can be continuously varied in continuous dependance on the intensity and/or position of an external source of the same type of radiation, e.g. the headlamps of an approaching vehicle, as determined by a radiation sensitive receiver operatively coupled to the radiation transmitter. The invention is particularly described as applied to the automatic control of a car's headlamps in dependance on the position of the headlamps of an oncoming car. A car 10 Fig. 1 is provided with two headlamps 11 and 12 arranged to be pivoted about vertical axes under the control of electric motors 22, Fig. 3, such that the beams emitted thereby, normally directed dead ahead, are moving inwards as in Fig. 1. Each motor is under the control of a photo-cell 19 and its amplifier 21a, such that when the beamed radiation from an oncoming car 10a is detected thereby, the beams are pivoted inwards such that the oncoming car is within the zone of darkness 13a Fig. 2 in between the two crossed beams. The amount of crossing of the two beams is increased as the oncoming car 10a gets nearer, the beam 14 illuminating the side of the road, until the amount of beamed light reaching the photo-cells decreases as the oncoming car passes, whereupon the two beams swing back into their normal dead ahead position. An auxiliary lamp, manually operable if so desired, may be provided on the car 10 to illuminate the road in the zone of darkness in front of the oncoming car, the said lamp being automatically controlled to dip as the two cars approach. The presence of scattered, i.e. none beamed, light in the light from the oncoming car 10a can upset the operation of the arrangement as so far described. To overcome this the main photo-cell 18, Fig. 5, may be placed at the focus of a parabolic reflector 19, with a compensating photo-cell 18a placed outside the said focus and electrically connected in opposition with the photo-cell 18. The receptive faces of the two photo-cells are placed to the side so as to receive only light reflected by the parabola. The arrangement is such that beamed rays 24 fall on the main photo-cell 18 only, while scattered rays 25 fall on both photo-cells producing equal but opposite currents therein which cancel out. The invention can also be used between an aircraft and signal towers to direct radar beams for short distance communication, or as a landing aid in fog. Ultra violet or infra-red light may also be used.

Abstract: 1,188,787. Pneumatic despatch apparatus. SIEMENS A.G. 13 Aug., 1968 [14 Aug., 1967; 16 Aug., 1967], No. 38579/68. Heading B8A. In a pneumatic shuttle-conveying system with stations, arranged along a pneumatic tube, which can act as transit, despatch or receiving stations, each station is provided with at least two banks of keys for destination determination through coded destination signals in a destination control circuit, the number of keys in the banks at each station being such that the product of the number of keys in each of the banks is equal to or greater than the number of stations in the system. To monitor the despatch and removal of shuttles, a circuit is provided incorporating a test relay, which responds when the destination is selected, and a travel relay, which responds when the shuttle is despatched, the energizing of the test relay being cut off whilst a shuttle is travelling through the system. The monitoring is effected through the provision at each station of a light source and a light receiver by means of which central switching equipment common to all the stations can be operated. The arrangement is such that the light receivers in stations operating as transit stations are masked by movable components of these stations and those in stations operating as receiving stations are uncovered. The despatch of a shuttle is then initiated by the uncovering of the light receiver at the destination station and the return of the station to its initial position is trigg:red by the temporary masking of the light receiver on the arrival of the shuttle. Detailed circuits, Figs. 5, 6 (not shown), for systems in which the stations have two key banks each with three keys or have three key banks each with three keys are described.

Abstract: 1,094,742. Driving record tapes. BSR Ltd. Oct. 8, 1964 [Oct. 10, 1963], No. 39923/63. Heading G5B. The tape spool carriers 11 are fixed to the upper ends of respective spindles 16 which pass axially through their associated continuously driven drive pulleys 18 and, at their lower ends, are rotatably supported on bridges 19 carried by clutchactuating levers 20 pivoted at their rear ends 31 to the tape deck 10. Normally, when the tape drive is inoperative, both spool carriers are held in a raised position out of driving engagement with their drive pulleys. Operation of the " rewind " and " fast-forward " keys 25, 26 rock, through associated rods 27, a corresponding one of the two clutch actuating levers 20 downwardly, causing the associated spool carrier to fall under spring action 21 until it engages its drive pulley through a friction pad 23. The usual interlocking between the control keys is effected by a sliding spring-biased latch plate 40, Fig. 5, mounted beneath and parallel to the tape deck. Depression of the start key 32 also operates the R.H. clutch actuating lever 20, through an extension arm 35, to drive the R.H. take-up spool and through a lug 41 advances the latch plate 40 whereby the pinch roller 43 resiliently carried thereby is moved to effect tape drive by the capstan. At the same time spring-urged felt pads (45) also carried by the plate 40 press the tape against the heads. In this forward position of the latch plate 40 depression of the " rewind " and " fast forward " keys 25, 26 is prevented by pegs 54 rigid with these keys engaging the portions 56 of the plate 40. However, in the stop condition, operation of either the " rewind " or " fast forward " key 25, 26 prevents forward movement of the latch plate and hence prevents operation of the start key. The tape is also withdrawn from the heads by two fingers on the latch plate as the latter is retracted by operation of the stop button 33. During " rewind " and " fast forward " operation the head signals are thus muted and tape wear prevented. For recording, a spring-urged arm is rocked clockwise and a peg on this arm enters a slot 63 in the latch plate, which, when moved to its forward position on depression of the start key thereby holds the " record control " operative until operation of the stop key 33. The pause key 34, when depressed to the full extent, operates the L.H. clutch actuating lever 20 at the same time as it rocks a further lever to disengage the pinch roller so that capstan drive of the tape is interrupted and the tape brought to rest as the slipping drive on the R.H. spool is balanced by that on the L.H. spool. The usual counter 67 is driven through a belt 70 by a pulley on the lower end of the R.H. spool carrier spindle. Braking arrangements are as described in Specification 1,094,741.
