The said automatic mechanism comprises a lever member 42, Fig. 2, biased by a spring assembly 44 for pivotting about the axis of a hub portion 61 such that when during uncoupling from a mated coupler, the knuckle of the mated coupler moves to release pressure on the front face 46b of a plunger 46, the lever member 42 pivots to cause a roller 64 to engage a cam 40 and effect pivotting of the rotor shaft 32. The railway car coupler may be of the A.A.R. Standard "F" type. As illustrated, the lever member 42 comprises: an arm 82, Fig. 8, bearing a trunnion 82a for engagement in a slot of the plunger 46; an arm 62 which has a bifurcated end carrying the roller 64; and a pair of arms 70 having recessed bearing portions 70a for receiving trunnions (74a), Fig. 4 (not shown), of the spring assembly 44.

Abstract: 1462776 Fusible cut-outs OTTERMILL Ltd E G WRIGHT and E BURT 22 Nov 1974 [29 Nov 1973] 55432/73 Heading H2G A base member for a fuse unit has a shield 40 of polyamide, polypropylene or polytetramethylene terephthalate based polyester comprising a first part 41 which may be flexed relative to a second part 42 mounted on a body portion 44, the first part being capable of occupying either a position in which it precludes accidental contact with the terminal 12 or a position in which it allows access to the terminal. The first and second parts are joined by a portion 45 of reduced cross-section. The first part of the shield is held in the shielding position by side projections 53 releasably engaging over vertical ribs 52 on the walls 11 of the body portion, projections 51 on the first part engage against ribs 52 to determine the alternative position of the first part. In this position the first part tends to prevent complete insertion of the fuse carrier (20, Fig. 6, not shown). The second part of each shield is L-shaped and has a transverse slot (46, Fig. 9, not shown) in the underside of the horizontal leg (47) for gripping engagement with a rib (48) on the base 43, the leg (47) also having a pair of ears 49 locating under projections 50. In a further embodiment an alternative shield (29, Fig. 3, not shown) is retained in the body portion (10) by having an end (25) trapped between a terminal 12 and the base (16). An upstanding rib (32) on the base (16) locates the shield and has a sloping surface (33) to limit the flexing movement of the shield. The second part of the shield may also be fixed to the body portion by screws or rivets.

Title: Reversible counting device
IPC: H03K23/56
Filed: 1971-12-06
Abstract: 1336953 -Reversible counters BENDIX CORP 6 Dec 1971 [14 Dec 1970] 56568/71 Heading G4A A pulse counting system arranged to add pulses applied at 64 and subtract pulses applied at 66 comprises an input circuit feeding a counter 12 and including delay circuits so that it can accommodate two consecutive applied pulses whereby, when it is determined that the next pulses to be applied to the counter will cause the accumulated count to pass through zero, the signals necessary to change the counter 12 from incrementing to decrementing or vice versa can be generated before the counter actually reaches zero thus allowing counting at maximum speed. The counter 12 operating in binary coded decimal comprises several decades 20-26. Pulses applied at 30 are fed via an inverter 32 to the units stage 20; as each stage reaches a count of 9 or 1 depending on the counting direction it issues a signal at terminal U/D to condition a gate 34-38 so that the next pulse is applied as a carry pulse to the next stage. The direction in which the counter counts is determined by a signal applied to terminals MC froma line 28. The two input pulse trains at 64, 66 are added together by OR-gate 84 and fed to the input 30 of the counter 12. The signal on 28 which determines whether each individual pulse is to increment or decrement the counter 12 is derived from a gating unit 18 which issues a new signal for each input pulse to the OR-gate 84 and is also controlled by a sign flip-flop 74. When the latter is in the state indicating the count is positive the unit 18 issues signals to 28 causing pulses from 64 to increment the counter and pulses from 66 to decrement it. When the sign flip-flop changes over the signals have the opposite effect. A gating unit 40 provides an output whenever (a) the counter 12 is registering 1 and is conditioned to be decremented by the signal on 28 and (b) a pulse to be counted has passed a point 58. This output enables an AND gate 68 which sets the sign flip-flop 74 according to whether the next pulse arrives on line 64 or 66.

[Also in Division E2] The backrest of a vehicle seat is maintained at a selected position of angular adjustment by teeth 21 meshing with those 9 of fixed rack 8. In order to separate teeth 9 and 21, handle 17 is raised, against the force of spring 19, to move bearing surface 16 eccentrically about the axis Y-Y, of bearing surface 12 of sleeve 10. Sleeve 10 is normally secured relatively to bolt 4, thus allowing the hinge member 3 to rotate about the axis Z-Z of its bearing surfaces 16 and 20. To adjust the axes Y-Y and Z-Z, relatively to the fixed axis X-X of bolt 4, nut 22 is slackened and sleeve 10 is turned about the bolt 4 until the best position of interengagement of the teeth 9, 21 is obtained. When the member (3a) on the opposite side of the backrest pivots about the fixed axis X-X, the eccentric movement of member 3 is accommodated by elastic deformation of the backrest frame (2). Alternatively, an elastomer may be provided in the pivot (4a, 5a).

Abstract: 1,148,700. Flocking textile materials. SINGER CO. 29 Dec., 1967 [31 Dec., 1966], No. 59101/67. Heading D1L. Textile materials including filaments and yarns are electrostatically flocked by conducting an adhesive coated material through an atmosphere of flock generated by an electrostatic field acting on a source of flock material, the electrostatic field being generated by a main electrode and an activating electrode of the same polarity but higher potential and a complementary electrode of opposite polarity, the adhesive coated material being passed between the complementary electrode and the main and activating electrodes in the direction from the activating electrode to the main electrode. A flock material is fed from a hopper 20 via rotary distributing devices 21, 17 onto an earthed sieve floor 19 through which the flock passes onto a moving endless conveyor 8 whence it is conveyed into the flocking apparatus. The belt 8 passes between an upper vibratory complementary electrode 5 having a positive potential and lower activating electrode 2 and main electrode 3 both of negative potential, but that of electrode 2 being greater than that of electrode 3. Electrode 3 is situated downstream of electrode 2 and is separated therefrom by a gap A sufficient to prevent flasbover. Simultaneously a plurality of parallel filaments or yarns are fed through a device 26 in which they are coated with adhesive and thence through the flocking apparatus passing above the belt 8 but below upper electrode 5. A cover plate 4 is placed over the flocking apparatus to enclose the flocking chamber. To ensure an even distribution of the flocking material the base of the sieve 19 is divided into three trapezoidal sections the outer two of which have a larger mesh size so that the peripheral areas of the belt are not deficient in the material when the belt enters the flocking apparatus. In a preferred embodiment the activating electrode was given a potential of between -33 and -60 KV, the main electrode a potential of between -30 and -40 KV and the complementary electrode potential of between +40 and +45 KV.
