Abstract: 1,188,094. Gear cutting. FABRIQUE DE MACHINES ANDRE BECHLER S.A. 23 Aug., 1968 [13 Sept., 1967], No. 40356/68. Heading B3K. An attachment adapted to be mounted on the rotary table 1 of a gear hobbing machine for holding a bevel gear blank P in adjustable angular relation to the hobbing tool 0, i.e. so that bevel gears may be cut or ground by the machine, comprises a plate 2 and shaft 5 adapted to be fixed to the table 1 and to rotate therewith, the shaft 5 supporting and driving a first bevel gear 9. A housing 6 rotatably mounted on the plate 2 and arranged to be held stationary by adjustable arm means 43, 44, 45 fixed to a stationary part of the machine carries, on an axis at right angles to that of the gear 9, a second bevel gear 16 in mesh therewith. The housing 6 also carries an angularly adjustable support comprising plates 21 ... 24 adjustable about the same axis as that of gear 16 and of a trunnion 20, the support carrying a work spindle 35 and mounted thereon a third bevel gear 38 at right angles to and in mesh with the second bevel gear 16.

Title: Automatic slack adjusters for vehicle brakes
IPC: F16D65/22
Filed: 1975-10-03
Abstract: 1509398 Brake slack adjusters; actuators GIRLING Ltd 9 Sept 1976 [3 Oct 1975] 40452/75 Heading F2E An automatic slack adjuster comprises a strut assembly 8, 9, of which the effective length is adapted to be increased to maintain the braking clearance constant, adjusting means comprising an adjuster member (e.g. a drive ring 24) engageable (indirectly) with a part (e.g. thrust member 9) of the strut assembly and movable with the strut assembly longitudinally in a brake-applying direction after the braking clearance has been taken up, and locking means (e.g. releasable wedging engagement between drive ring 24 and a tapered bore 25) for locking the adjuster member against movement with the strut assembly in the opposite (brakereleasing) direction beyond a distance necessary to establish the clearance, whereafter engagement between drive ring 24 and thrust member 9 causes the latter to rotate relative to tappetpiston 8 to increase the effective length of the strut assembly by a screw-threaded engagement between components 8, 9; the drive ring 24 acts on thrust member 9 through a driven, ring 29, and an overload spring 32 urges a clutch face 33 on the driven ring 29 into engagement with a complementary clutch face 34 on thrust member 9 so that the driven ring 29 and thrust member 9 are normally movable together, but the spring permits the clutch faces to disengage if a thrust acting on thrust member 9 in the brake-releasing direction exceeds the overloading of the spring, whereafter the driven ring can rotate relative to the strut assembly to preclude adjustment. Thus, during brake release, as thrust member 9 is moved from right to left, drive ring 24 returns to wedging engagement with bore portion 25, and later, the lost motion between teeth 27 on drive ring 24 and teeth 28 on driven ring 29 is taken up. Thereafter, if the force of leftward movement of thrust member 9 is excessive, (e.g. during vehicle rollback when re-starting on an uphill gradient), driven ring 29 will be held by drive ring 24, spring 32 is collapsed by abutment 31 on member 9, and clutch face 34 on thrust member 9 will separate from clutch face 33 on ring 29. Thereafter, it does not matter if spring 32 forces ring 29 to rotate because ring 29 cannot rotate member 9, so adjustment does not occur.

Title: Improvements in or relating to devices for converting electric signals into mechanical displacements
IPC: H03M1/00
Filed: 1959-12-01
Abstract: 917,664. Electric selective signalling systems. MEFINA S.A. Dec. 1, 1959 [Dec. 3, 1958], No. 40814/59. Class 40 (1). In a device for converting a combination of two-state electrical signals into a corresponding mechanical displacement energy to effect the displacement is derived from a continuously rotating shaft. As described, each input it has associated with it two levers 7, 8, Figs. 2, 4, freely mounted on a shaft 9, the levers being rocked about the shaft 9 by an eccentric pin 2 on a continuously rotating shaft 1 via links 3, 5 and 6. The arrangement is such that starting from the position shown in Fig. 2 the levers can either be rocked outwards symmetrically (not shown) or, if one of two coils 17, 18, is energized they can be rocked outwards asymmetrically. Fig. 4 shows the result of momentarily energizing coil 18 which momentarily prevents lever 8 rocking until lever 7 has moved slightly, whereupon a raised portion 23 on the link 6 latches in a fixed member 22. Thus substantially all the energy used to displace the lever 7 is derived from the continuously rotating shaft 1. In order to derive a single resultant mechanical displacement representing the incoming signals, each pair of levers 7, 8 is associated with a wedge 14, Fig. 5, the wedges being juxtaposed as shown and having a thickness corresponding to the weight of the bit with which they are associated. Thus the resulting output is a displacement of a member 24, Fig. 5, since the extreme right-hand wedge bears on a fixed support 4.
