Abstract: 1482884 Non-contact-making switches STANDARD TELEPHONES and CABLES Ltd 27 Nov 1975 48773/75 Heading H3X Depression of a key 19, Fig. 6, in a coded keyboard moves a saturating magnet 17 away from a two-aperture transformer core 10 individual to the key, and so permits magnetic coupling between one or more pulsed conductors and an output conductor threading the same aperture, coding being effected by distributing a plurality of sequentially pulsed conductors 16 between the two apertures and by providing in each aperture one of two output conductors representing "1" and "0" respectively. A core is formed by two E-portions bonded together after the conductors have been selectively distributed between the two channels 11, 11a presented by one E-portion as shown in Fig. 3. A key is held in the raised position by magnetic attraction between the magnet and core, while in the depressed position the magnet may move in proximity to a flux diverter, Fig. 8 (not shown), to ensure complete desaturation of the core. In a particular example nine sequentially pulsed conductors are provided together with a parity check conductor. The first, second and ninth pulsed conductors are threaded through a core aperture of the exemplified key, this aperture including the "1" output winding. The other pulsed conductors are threaded through the second aperture which also includes the "0" output winding. The sequential pulse pattern is as shown in Fig. 7, and for this particular key the output, when depressed, is as shown in Fig. 7(a) for the "1" and "0" conductors. Output logic may be provided to detect simultaneous "1" and "0" outputs arising from improperly operating two or more keys at the same time, and to identify incomplete key depression by detecting missing pulses. Such erroneous outputs are shown in Figs. 7(b) and 7(c).

Abstract: 1,091,407. Spherical joints. ILLINOIS TOOL WORKS Inc. Dec. 8, 1964 [Dec. 30, 1963], No. 49917/64. Heading E2F. [Also in Division F2] A spherical joint for a shaft 40 comprises a part-spherical bush 10 that is made of a resilient synthetic-plastics material and contains a cylindrical bore 18 with a reduced diameter at one end thereof so as to define a shoulder 20, which engages with an annular groove 46 in said shaft, the radially - outermost peri - pheral-surface of the bush being engaged by the wall of a cylindrical bore 32 in a block 30. The external diameter of the bush is slightly greater than the diameter of the bore 32 to effect firm contact between the bush and the block. The joint is assembled by placing the bush in the bore 32 in abutment with a shoulder 34 at one end thereof and then driving the shaft 40 into the bore 18 until the shoulder 20 is lodged in the groove 46, the bush being subsequently retained in the bore 32 by friction. To facilitate assembly of the joint, the bush is split longitudinally, Fig. 2 (not shown). To obtain satisfactory contact between the bush and the wall of the bore 32, the bush may be moulded with one half thereof radially displaced relative to the other half so as to form diametrally-opposed shoulders (15), Figs. 4 and 5 (not shown). Alternatively, the outer surface of the bush may contain a plurality of grooves, ribs or nodules, Figs. 6 to 14 and Figs. 16 and 17 (not shown), and for details of these modifications the Specification should be consulted. The wall of the bore 18 may contain axially-orientated ribs (19g), Fig. 15 (not shown), which engage with the shaft 40. Axially-orientated ribs (14j), Fig. 18 (not shown), may be formed on both the internal and external surfaces of the bush. The bush may contain axially-orientated grooves (14n), Fig. 19 (not shown), and deformable projections (21n) on a flat surface defined by a portion of the bush that closes one end of the bore 18, which projections are engaged by the end of the shaft 40 when the latter supports an axial load acting in the direction of the bush.

Apparatus for feeding ampoules into prefabricated receptacles comprises a feed hopper 2 having an outlet disposed above a rotatably mounted conveyer drum 1 in the form of a truncated cone, the surface of which drum has a plurality of grooves shaped to receive a plurality of ampoules, means for feeding corrugated receptacles to a loading station beneath the drum, the lower portion of the interior of the hopper 2 tapering to an asymmetrical throat section leading to the outlet and comprising two oppositely disposed guiding surfaces 12, 13 for accommodating a plurality of ampoules therebetween, the guiding surface 12 facing in a direction counter to the direction of rotation of the drum 1 terminating in a curved portion. In the machine shown, ampoules 10 in a sloping hopper 2 (Fig. 2, not shown), drop into recesses 6 in the tapered drum 1 and are carried thereby into corrugated receptacles, Fig. 3, fed from a magazine 4 by dogs 5 on a belt 3. The ampoules are restrained from jamming by the curved portion of the surface 12 of the hopper, and are held in the recesses 6 by cover strips 11 which allow broken ampoules to pass between them. Rollers 18 push the ampoules firmly into the corrugations. The receptacles may be one continuous strip which is cut between groups of ampoules after filling. Parts of the machine are preferably of transparent plastics material so that the filling operation can be viewed. When a more upright hopper is employed it is provided with a front cover sheet.

Abstract: 1,078,624. Hydraulic intensifiers. R. LEHLE. Dec. 15, 1964, No. 51300/64. Heading F1P. The driving piston 3 of a hydraulic intensifier provides an oil reservoir 6 covered by a flexible diaphragm which when subjected to air pressure from a line 17 and a valve 18 forces oil through an axial bore 9 and a check valve 10 of the piston rod 4 into the pressure space 13 of the working cylinder 12 to effect rapid displacement of the working piston 14 until the latter becomes loaded whereon the resulting pressure rise in space 13 causes valve 10 to close and valve 20 to reverse to vent the underside of the driving piston 3 which is then forced downwardly by the air pressure above it and thus pressurizes the oil in space 13. To effect the return stroke valve 18 is manually reversed to vent the space 7 above diaphragm 5 and pressurize a space 16 below piston 14, and the pressure drop in space 13 reverses valve 20 to direct air pressure from line 17 into cylinder space 8. In a modification the working cylinder is separated from the driving cylinder and both the driving piston and working piston are returned by a spring.

Abstract: 1522274 Locking device for seat belts GRANGES ESSEM AB 8 Dec 1976 [9 Dec 1975] 51310/76 Heading A3V A locking device for a seat belt of the kind in which the seat belt is automatically retracted when not in use and locks against withdrawal if rapidly withdrawn comprises a disc-like body 16, Fig. 2, that rotates with a shaft 11 when the belt is wound on or off said shaft, an inertia disc 23, Fig. 3, rotatable on the shaft 11, a spring 26 that tends to keep the inertia disc 23 in a predetermined angular relationship with respect to the disc-like body 16, a fixed annular member 17 surrounding the disclike body 16 and locking members 19 carried in slots 24 in the inertia disc 23 and extending into an annular space 20 between the body 16 and the fixed annular member 17, the arrangement being such that when the inertia disc 23 and the disc-like body 16 are held in said relative position by the spring 26 the slots 24 in the inertia disc 23 guide the locking members 19 to a radially retracted non-locking setting as shown in Fig. 2, but if the belt is suddenly unreeled the disclike body 16 is rotated relatively to the inertia disc 23 and this relative motion causes the locking members 19 to ride radially outwardly in the slots 24 to a locking setting between the disc-like body 16 and the fixed annular member 17. As shown in Fig. 2 each locking member 19 is associated with two notches 21, 22 in the disc 16, the locking member 19 moving from the deeper notch 21 to the shallower notch 22 on relative movement between the two discs 16, 23 due to a sudden unreeling of the seat belt. When a  locking member is in its shallower notch 22 it locks with notches 18 formed in the fixed annular member 17 and so stops further unreeling of the seat belt. In Fig. 3 a pendulum arm 31 is also provided. Any rocking of the vehicle causes the pendulum arm 31 to swing to a setting in which it moves a pawl 29 into engagement with teeth 32 on the inertia disc 23 and so prevent rotation of the inertia disc 23.
