The intermediate member 9 having holes 19 whereby the intermediate member 9 is selectively secured to the fork 8, and also having holes 17 whereby the intermediate member 9 is selectively secured to the brake lever 10, thereby to provide the brake lever 10 with various effective lengths according to which particular holes are utilized for securing the intermediate member 9 to the fork 8 and the lever 10. As shown, the lever 10 forms part of a housing 11 of a known automatic adjuster device 12 and is rotatable about the pivot axis of a brake shaft 13 to actuate a mechanical drum brake. Lever 10 has three holes 15, and there are two said holes 17 in a fork 16 of member 9 and two said holes 19 in a connecting plate 18 of member 9. A pin 20 secures fork 8 to member 9 utilizing one or other of holes 19, and two pins 21 secure lever 10 to member 9 utilizing holes 19 and two holes 15. The member 9 may also be turned through 180 degrees before securing. In the embodiment of Fig. 3 (not shown) the holes (19) have their centres on a line parallel to the line connecting the centres of holes (15), unlike the embodiment of Fig. 1 wherein the lines are at an acute angle.

Title: Apparatus for dispensing cap lining material
IPC: B65D53/06
Filed: 1976-11-24
Abstract: 1531310 Dispensing extruded cap lining material JAPAN CROWN CORK CO Ltd 24 Nov 1976 [16 Feb 1976] 48984/76 Heading B5A Caps or crowns 10 are each provided with a slug 9 of material for subsequent moulding into a liner, by continuously sequentially conveying the caps or crowns, e.g. by a rotary turret, along a path below an extrusion outlet from which the slugs 9 of extruded cap lining material are sequentially cut and pressed into the centre of each cap or crown, by a blade 4 which continuously rotates across the outlet 8, to approach and depart from the path at a rotative speed which gradually decreases during the approach and gradually increases during the departure.  Preferably, Fig. 6, the speed component "x" of the blade along in the direction of the path, is substantially constant and equal to that of the conveying along the path. The decreasing and increasing rotative speed of the blade avoids difficulties that would otherwise occur at a uniform rotative speed, of the radially outer tip of the blade colliding on its approach with a deep skirt 11 of a cap, and of the blade tip having a speed component along the path which is higher than that of the cap and thereby displacing the slug from the centre of the cap.  The decrease and increase of speed may be effected by a link or cam mechanism, or as shown by intermeshing non-circular gears 31, 33, driven from a reduction mechanism 21 which also rotates the turret at a gear 25.

Abstract: 1400730 Electronic watches SOC SUISSE POUR L'INDUSTRIE HORLOGERE SA 25 Oct 1972 [25 Oct 1971] 49288/72 .Heading G3T [Also in Divisions G4 and H1] In a timepiece of the kind described in Specification 1177523 and having an oscillator which drives a gear train via frequency dividers and an electro-mechanical transducer, a variable capacitor which is used to detect errors in the mechanical counting system comprises a movable electrode system 5 which is normally biased by a spring S into engagement with fixed vanes 7a but which is periodically displaced by the timepiece gear train. The electrode system 5 consists of a set of circumferentially spaced vanes of oxidized aluminium fixed to a shaft 6 which carries a finger 11. The finger is displaced periodically by protrusions 2 on a wheel 1 which is attached to shaft 3 of the timepiece ratchet wheel, as the latter is rotated by the transducer. Circuits are described Figs.2, 3 (not shown) for detecting a lag or lead of the gear train with respect to the correct position as determined by the timebase oscillator. The variable capacitor (C4) is used as one arm of a voltage divider to which are fed pulses (V9, Fig.4 (not shown) derived from the frequency divider chain. If a pulse arrives when the capacitor has its maximum value, no corrective action is taken. If the capacitor is not in this position, the lag or lead error of the train is corrected by advancing the transducer by an additional step or causing it to miss a step.
