Abstract: 1,028,759. Selective signalling. LUFKIN RESEARCH LABORATORIES Inc. Sept. 22, 1964 [March 9, 1964], No. 38606/64. Heading G4H. In a shaft position encoder, for example for a watt-hour meter, ground G, Fig. 7, is selectively connected, by a four-brush wiper, to coded segments A, B, C and D to produce combinations of markings in accordance with the code shown in Fig. 10, where a " 1 " represents ground potential and an " O " represents a floating condition. The code is monophylic except for the changes from 9 to 0 and 0 to 1. Errors at these points arising from non-simultaneous changes are prevented by making the ground segment G dicontinuous. Thus in going from 9 to 0 the ground segment G, Fig. 11, stops before segments B and D, and therefore ground potential is removed from B and D simultaneously. Similarly the ground segment starts again after the A segment.

Abstract: 1,225,741. Keyboards. ING C. OLIVETTI & C., S.p.A. 1 Jan., 1969 [13 Feb., 1968], No. 143/69. Heading G4H. A keyboard comprises a set of keys 1 each bearing directly on a metal tongue 2 making contact with one contact a<SP>1</SP> in the unoperated position and another 6<SP>1</SP> in the operated position, the contacts serving to connect the biasing wires of a bi-stable magnetic core 5 to negative and positive sources respectively so that the core is saturated in its two different senses in the two positions and in changing induces in output wires U1-U4 a coded combination of pulses representing the operated key. The tongue 2 is resilient and has humps a, b which make contact in the two positions, with a slight sliding motion due to the bending of the tongue. In the unoperated position the tongue rests on the lower contact as shown. When the key is pressed it deflects the tongue against a fulcrum F, raising the hump b against contact b<SP>1</SP> a stop F. Instead of using two separate sources E, E<SP>1</SP> a single source may be used, being switched to one of two oppositely wound biasing wires to produce the same effect. The tongue in this case may be permanently connected to the source and arranged to energize one wire or the other. The tongues may be integral, formed by cutting a metal sheet to leave the tongues connected to a central spine. The signals are magnetically amplified, being applied to the primaries of small transformers. The output from the secondary winding is applied to a diode to suppress one of the output signals, e.g. the negative signal caused when the core switches back to its initial position.

Abstract: 1,228,805. Forcing liquids by gaseous pressure. SIEMENS A.G. July 1, 1968 [June 30, 1967], No.31415/68. Heading F1R. Apparatus for conveying a liquid, e.g. electrolyte in a fuel cell, or corrosive liquid, from a low level reservoir 22 to a high level reservoir 27 comprises chambers 19, 25 connected by reducing valve 30 to a pressurized gas container 31, e.g. oxygen for flushing the fuel cell, and by non-return valve 21 to reservoir 22. In operation, with liquid at level 32 in chamber 19, gas entering chamber 19 from container 31 passes to atmosphere via chamber connection 24, chamber 25, pipe 26 and reservoir 27. The head of liquid in reservoir 22 opens valve 21, and the liquid rises in chamber 19 to level 33, at which syphon 23 operates to discharge liquid from chamber 19 into chamber 25. The liquid in chamber 25 prevents the gas from passing to atmosphere, and the gas pressure above the liquid in chambers 19 and 25 rises and acts to close non- return valve 21 and to force the liquid in chambers 19 and 25 into reservoir 27. When all of the liquid has been discharged from pipe 26, the gas is free to pass to atmosphere and the pressure in chambers 19 and 25 falls, permitting valve 21 to open and another cycle to begin. In Fig.2, (not shown), chamber 25 is incorporated within chamber 19. The gas spaces of reservoirs 22 and 27 may be connected for pressure equalisation.

A toy structural element made of a synthetic plastics material comprises a core element 1 with connecting elements, consisting of a plurality of pin-like prongs 2 arranged in longitudinal and transverse rows, disposed on at least one outer surface 3 thereof, the prongs being adapted to engage with the prongs of other structural elements thereby forming an interlocking frictional connection. The prongs are spaced from one another by a constant distance, the prongs of a second structural element thus engaging in the gaps between adjacent prongs on a first structural element. The structural elements may be shaped, e.g. as cubes, cuboids, circles or as segments of a circle. The (core) element may also be provided with one or more openings. Optionally the connecting elements are disposed on a thinwalled base body which is susceptible of being connected, e.g. by glueing, by magnetism, by provision of a sliding guide arrangement, by a screw connection, or by interlocking parts or clips, to a part which determines the shape of the structural element. Thus in one embodiment the structural element is a wheel (see Figs. 13 to 23, not shown).

Abstract: 1,259,147. I.C. engine fuel injectors. ROBERT BOSCH G.m.b.H. Oct. 24, 1969 [Oct.26, 1968], No.52167/69. Heading F1B. A fuel injection valve for an I.C. engine comprises first and second passages for conveying fuel to a pressure chamber, a control member controlling the flow of fuel through the first passage and a restrictor or throttle in the second passage, the control member in its normal position opening the first passage and being displaceable to close the first passage against the action of a spring. Fuel from an injection pump passes to the spray aperture 11 via passages 15, 16 in parallel, an annular groove 17, a passage 18 and a chamber 9. A slide valve 21, which is held open by a spring 20, is interposed in the passage 15. When the engine is idling or operating at low load, an electromagnet 28 is energized by a switch operated by, e.g., the regulating rod or adjusting lever of the injection pump and moves the valve 21 against the action of the spring 20 to close the passage 15. The fuel then flows only through the passage 16 which contains an inter-changeable throttle 19. The throttle 19 prolongs the injection period, which would otherwise be short because of the smallness of the quantity of fuel injected at idling or low load. The prolongation of the injection period reduces combustion noise. To relieve the pressure in the chamber containing the return spring 10 of the needle valve 8, in the chamber 32 and in the cavity of the electromagnet 28, inter-connecting passages 31, 32<SP>1</SP> and a passage 33 leading to a leakage line (not shown) are provided.
