Abstract: 1,233,217. Latch fastenings. EMERSON ELECTRIC CO. 4 Oct., 1968 [13 Oct., 1967; 31 May, 1968], No. 47287/68. Heading E2A. [Also in Division F4] A light-transmitting enclosure is attached to a supporting housing by latches adapted to hold the enclosure in either a first "closed" position in abutment with the housing or in a second "open" position spaced from and below the housing, each latch having an outwardly-extending hook-shaped part adapted to engage beneath an inturned lip on the enclosure and being movable in an outward-inward direction to permit engagement with, or disengagement from, the lip. An outwardly-extending shoulder is formed on each latch above the hook-shaped part and is engaged by the lip when the enclosure is raised from its second to its first position, such engagement causing the latches to move from the positions in which they hold the enclosure "open" to the positions in which they hold the enclosure "closed". In a first embodiment, Figure 5, each latch is mounted on the housing 7 by means of a spring 60 which permits the hook-shaped part 63 to move inwards so that it can be engaged with the lip 54 of the enclosure 5 when the enclosure is to be suspended in the second position. Upward pressure on the enclosure causes the lip to ride up the cam surfaces 69 of the latches and snap on to the shoulders 65 where it is held in the first position in abutment with a ledge 77 of the housing. The enclosure is moved from the first to the second position by the application of downward pressure. In a second embodiment (Figures 8-10, not shown) each latch plate (31) is pivoted to a bracket (11) secured to the housing and is biased towards the first  and second positions by an overcentre spring (21). In a further embodiment, Figure 12, each latch plate 231 is mounted on a pivot pin 227 slidable in slots 223 in the vertical side walls of a bracket 211 secured to the housing. The pivot pin is urged upwardly by a torsion spring 228 the free ends of which extend upwardly and outwardly through a slot 229 in the bracket 211. When the pivot pin is at the top of the slots 223, the enclosure 5 is in its first position, downward pressure on the enclosure causing the pin to descend to the bottom of the slots 223 and the free ends of the torsion spring to be compressed by the slot 229 so that they exert insufficient force to raise the latch member. In this lower position the latch member can pivot inwardly against the force of a leaf spring 241. In any of the embodiments the enclosure may be disengaged from the latches on one side when it is in its second position and hinged down on the remaining latches to obtain access to the interior of the housing.

[Also in Division H1] An anti-skid vehicle braking system responsive to tyre road surface conditions including a wheel speed sensor 30 generating pulses converted to a D.C. voltage level in a counter 32, which voltage is supplied to a device 34 which generates no output as long as wheel speed remains below a predetermined threshold value, the output of the device being an emitter follower 35 which reproduces upon its emitter any D.C. voltage applied to the input which is above the threshold value and the output being applied to a terminal X upon which is also established a minimum signal by a voltage divider comprising resistors 38, 39, 40 has also a device 42 responsive to linear acceleration of the vehicle and consisting of a tubular glass envelope containing mercury bridging electrical contacts mounted aligned with the vehicle fore and aft axis so that deceleration moves the fluid to open the circuit. The wheel acceleration signal is applied to comparators 50, 52, 54 wherein it is compared to a predetermined reference level. When the wheel decelerates to the reference level, comparator 50 generates an error signal triggering one shot 56 to trigger memory means 60 to impress thereon a voltage proportional to a predetermined percentage of the instantaneous wheel speed at the time of deceleration to reference level and if, during the time period defined by the period of the one-shot pulse, wheel speed should drop to the memorized wheel speed memory 60 generates an output which activates controller 62 to release the brake pressure.

Abstract: 1,257,158. Change-speed gear. FICHTEL & SACHS A.G 6 July, 1970 [10 July, 1969], No. 32549/70. Heading F2D. In a two-speed (step-up and direct drive). bicycle hub comprising planets 6 on an: input carrier 2 meshing a fixed sun 7 and ring gear 8, and 1st and 2nd pawl-and-ratchet one-way clutches 16, 17 and 19, 20 between the carrier 2 and ring 8 respectively and the hub shell 1, a back-pedalling operated control ring 22 retracts the ring pawls 19 for direct drive through the carrier pawls 16, the ring 8 idling, or releases the ring pawls 19 for radially outward movement into engagement with the ratchet 20 for step-up drive through the ring, the carrier pawls 16 ratcheting. As shown, the ring gear 8 is connected to a sleeve 18 forming a carrier for the, pawls 19 which axially extend into an internally cammed profile of the control ring 22 the cam profiles 28 of which serve to retract and disengage the pawls 19, whilst the cam profiles 30 effectively release the pawls 19 for outward movement into engagement with the ratchet 20. The direct drive pawls 16 are arranged on a carrier 13 screwably guided via a thread 12 on a sleeve 9 fast with the carrier 2, the sleeve 9 additionally supporting the control ring 22. Friction spring rings 44 and 32 serve to rotatably station the carrier 13 and control ring 22 during each back-pedalling gear-changing operation, whereby backward turning of the bicycle cranks through approximately 100 degrees will effectively ratchet the pawls 19 from one cam profile 28 to the adjacent cam profile 30, orvice versa, the back-pedalling operation being simply repeated for subsequent changes from one gear to the other. As shown in Fig. 1, further back-pedalling movement just beyond that required to effect a gear change further axially moves the pawl carrier 13 to engage and expand a brake 15 into frictional contact with the hub shell 1. Every time backpedalling is effected, for the purpose of braking, a ehange from one gear to the other unavoidably takes place. In Fig. 2 (not shown), the backpedalling brake feature is omitted.

Abstract: 1304085 Fluid actuation of switches AUTOMOTIVE PRODUCTS CO Ltd 23 July 1971 [1 Sept 1970] 41824/70 Heading H1N A fluid pressure operated electric switch comprises a plunger 35, Fig. 1, acting against resilient means 36, fixed contacts 18, 19, 20, a flexible bridging moving contact 27 (a helical compression spring) permanently in contact with fixed contact 18 and operable by plunger 35 from a position where it is out of engagement with fixed contacts 19, 20, to complete a circuit with firstly contact 19 and subsequently contact 20. The object is to indicate pressure decrease. When the pressure decreases, plunger 35 moves to the left from the switch open position followed by insulating member 28 which has a shoulder engaging spring 27, which shoulder is inclined to the longitudinal axis of the switch so that portion 33 of the shoulder is further from fixed contact 18 than portion 34. Consequently as plunger 35 moves to the left, spring 27 expands and the portion of spring 27 abutting shoulder portion 33 engages fixed contact 19 before the portion of spring 27 abutting shoulder portion 34 engages fixed contact 20. In a second embodiment, Fig. 2, the flexible moving contact 66 (not a spring) is a tapering helix, the larger end of which is permanently in contact with fixed contact 52 and the smaller end of which completes a circuit with firstly fixed contact 59 and subsequently fixed contact 53. In the normal pressure state, plunger 70 is to the right of the position shown with secondary metal plunger 62 to the right and insulating sleeve 68 under the action of compression spring 69 holding the smaller end of helix 66 to the right away from contact 53 and with the head 64 of secondary plunger 62 to the right out of contact with the smaller end of helix 66. As the pressure decreases, plunger 70 moves to the left, secondary plunger 62 moves to the left under the action of compression spring 65 and head 64 engages the smaller end of helix 66 completing a circuit between helix 66, head 64 and spring 65 to fixed contact 59. As plunger 70 moves further to the left, head 64 moves the smaller end of helix 66 against the action of spring 69 to the left to engage fixed contact 53.
