Abstract: 1,221,626. Two-part couplings. AMP Inc. 31 Oct., 1969 [25 Nov., 1968], No. 53368/69. Heading H2E. An electrical connector 2, for connecting a vertical printed circuit board 54 to a horizontal board 36, has an elongated body 4 extruded from nylon in a channel section with a rib 22 extending from channel base 6 and terminating in a thickened portion 24. Apertures 20, 20<SP>1</SP> are punched in the base 6 on both sides of the rib 22 at a spacing equal to that of apertures 34 in the horizontal circuit board 36. Contacts 26, also of channel form and each having a split, arcuate contact portion 38 struck from a base 28 between side walls 30, are inserted through the apertures 20, 20<SP>1</SP> from below until the upper end of each contact 26 engages a groove 14, 14<SP>1</SP> in a side wall of the housing 4 and a lip 18 of the groove latches with an undercut shoulder 48 on the contact. Terminal posts 32 of the contacts are then inserted through the holes 34 in the board 36 and soldered to conductors (52, Fig. 3, not shown) on the board's underside. When the vertical board 54 is inserted downwardly into the connector, the contacts 26 are restrained from pivoting about the base 6 by engagement of the lower portions of the contact side walls 30 with the thickening 24 on the housing rib 22. The board 54 may be polarized with respect to the connector 2 by means of a slot 61 in the board engaging with an insulating key 58 inserted in the housing between longitudinally spaced contacts 26.

Abstract: 1371258 Semi-conductor device BBC BROWN BOVERI & CO Ltd 30 Nov 1972 [3 Dec 1971] 55440/72 Addition to 1341309 Heading H1K A disc shaped semi-conductor device 1 (Fig. 1) is mounted between cooling bodies 2, 3 serving as electrical connections, clamping bolts 6, 7 engaging one of the bodies and extending past the other to engage a common yoke 8 which is biased away from body 2 by spring washers 10. These can be mounted as shown on a bolt 9 or in a cup-shaped member fitted into the recess in body 2, the bolt or the base of the member having an internal thread into which can be screwed a clamping screw 15 the head of which abuts the yoke. In manufacture a subassembly is first formed by screwing in screw 15 against the resilience of the washers until the face 11 on bolt 9, or in the alternative the rim of the cup-shaped member engages the yoke face. The subassembly, cooling bodies and device are then brought together and bolts 7 screwed into the yoke to the position shown at the right of Fig. 1, with their heads seated without play but with spring washers 17 the travel a of which equals the required spacing between the yoke and body 2 undeformed. Screw 15 is then released allowing spring washers 17 to be flattened by the resilience of washers 10 thus giving the spacing required to take up differential thermal expansion occuring in operation.

Abstract: 1389352 Fluid-pressure actuated switches PIANCO CONTROLS SpA 4 Dec 1972 [24 Aug 1972] 55843/72 Heading H1N In a device for monitoring fluid pressure changes, as in a vehicle tyre, a diaphragm 12, Fig. 1 for actuating a movable contact 17<1> encloses a chamber 11 containing fluid at substantially the same pressure as that to be monitored and also having the same temperature coefficient of variation of pressure. The arrangement permits equilibrium conditions to be maintained when normal pressure/temperature variations occur in the tyre. The movable contact arm 17<1> is integrally formed to extend from the end of a spring strip 17 which is preloaded by a second spring strip 21 whereby under normal conditions of loading when the pressure in the tyre equals that in the chamber 11 the contact 17<1> engages a fixed fulcrum 20 and is disengaged from a central contact pin 16 (broken lines in Fig. 1). If the tyre pressure drops, contact 17<1> engages contact 16 to close a circuit of signalling apparatus in the motor vehicle. A perforated cover plate 13 limits the movement of the diaphragm 12 to protect it against excessive deformation. In modifications the movable contact may be urged closed by a permanent magnet whereby snap-action closure is obtained. The movable contact 32<1> Fig. 8 may also be bent over at its end and engages a disc 31 attached to the fixed contact 16 whereby the signalling circuit is closed both on over-pressure and under-pressure.

The upstanding deckles are then compressed against the pulp portions 19. A number of such moulds are moved in turn on a rotary member 12 through a vat of pulp slurry, and when the mould is in a vertical position to operate a switch 28 a valve 32 is actuated allowing a blast of air to pass from an accumulator 34 through a hose 30 to the box. Each mould passes to a position beneath a pressure mould 16 which compresses the deckle, and the finished preform is fed to a conveyer 18.

The tensioning members 10 or their replacement force producing members may comprise spindles or hydraulic cylinders or diaphragms. The roller chains 9 are disposed side-by-side across the web width, the end faces of the rollers in adjacent chains being aligned so as to leave no gaps and the gaps between the rollers in each chain being staggered, Figs 5, 6 and 7 (not shown).

Heading G4H [Also in Division H1] A luminous display system comprises a plurality of units 12, which may be contained in a common envelope, each unit having an anode consisting of a plurality of selectively energizable parts for building up a desired character, and a grid to which a blocking potential may be applied. Characters circulating in dynamic store 18 are applied serially to decoder 21 the outputs P 1 -P 0  of which are connected to different combinations of anode parts in each unit 12.
