Title: Device for Producing Electrical Signals from Positions Distributed over an Area
IPC: G06F3/033
Filed: 1967-09-20
Abstract: 1,199,163. Electric selective signalling. LICENTIA PATENT - VERWALTUNGS G.m.b.H. 20 Sept., 1967 [20 Sept., 1966], No. 42843/67. Heading G4H. In a device for producing signals representing a position of a marker in a plane area two series of parallel conductors are provided arranged at right angles over the area, normally not touching at the cross-over points but caused to touch by the pressure of the marker, the voltage on the two series being equal but of opposite polarity so that upon contact at a cross-over point the conductors making contact are indicated by a zero voltage marking. The conductors may be connected to diode AND gates V 1 -V 10  and h 1 -h 10  to which a pulse is applied to read out the zero markings, a transistor inverter serving to convert this to a signal on an appropriate lead A 1 -A 10 , A<SP>1</SP> 1 -A<SP>1</SP> 10 . Resistors R in each conductor circuit limit the current when contact is made with a conductor of opposite polarity.

Filed: 1964-10-21
Abstract: A mercury cleaning apparatus consists of a reservoir 3 containing dirty mercury, an elongated chamber 2 (containing cleaning agent and communicating with the reservoir via a capillary tube 4) and a small bore tube 8 extending from within the reservoir to a nozzle 9 in the upper part of the chamber. When a vacuum pump is connected at 10 mercury is drawn up the tube 8, discharged from the nozzle, falls through the cleaning agent and passes through the capillary tube 4 back into the reservoir. Clean mercury is removed from an outlet 5. The cleaning agent may be sulphuric acid to remove water or nitric acid to remove zinc.

Abstract: 1,152,551. Measuring oxygen content electrically. BAILEY METER CO. Sept.27, 1966 [Sept.27, 1965], No.42998/66. Heading G1N. The oxygen content of a gas is measured and recorded by mixing the gas with a fuel, e.g. hydrogen and passing the mixture over a platinum filament 1 which is automatically maintained at a constant temperature (between 700 F. and 800 F.) by making the filament one arm of a D.C. bridge, the balance of which is sensed by a differential amplifier 13, which controls the energization of the bridge through transistors 15, 18. Thus as the temperature of the filament rises due to catalytic combustion, so the D.C. energization from battery 4 is reduced. The energization current is measured by the voltage drop across bridge arm 8 and is recorded, in terms of oxygen content, at 12.

Abstract: 1488830 Colour television INDESIT INDUSTRIA ELETTRODOMESTICI ITALIANA SpA 9 Oct 1974 [22 Oct 1973 12 June 1974] 43709/74 Heading H4F A half-line-frequency switching signal generator 14 in a PAL colour television receiver has its phase controlled in dependence on the output of a threshold detector 20 connected to the output of R-Y demodulator 15 receiving one input from subtractor 4 connected to a one (or three or five) line delay 5 and the circuit input, and receiving a reference signal input from PAL- switch 13. A burst gate 2 is controlled by a pulse shaper 7 receiving the switching signal from generator 14 and line synchronizing pulses 7 and transmits every second colour synchronizing burst to subcarrier oscillator 9; if the phase of generator 14 is correct oscillator 9 provides an output of B-Y phase and demodulators 10, 15 provide B-Y and R-Y outputs respectively, gates 16, 17 being blocked during line flyback intervals. If the phase of generator 14 is incorrect oscillator 9 provides an output at 90 degrees to the B-Y phase and demodulator 15 provides, due to delay 5 and subtractor 4, substantially no output; threshold detector 20 then blocks a gate 8 to block gates 16, 17 and to block generator 14 until it is in the correct phase. A second threshold detector may be connected to the output of the B-Y demodulator 10, which receives an input from adder 3, the outputs of the two threshold detectors being fed via an OR gate to gate 8. In an alternative embodiment the output of the B-Y demodulator is fed to a second threshold detector (57, Fig. 3, not shown), the outputs of the threshold detectors 20, (57) being supplied via an OR gate (56) to one input of a differential circuit (55), the output of which controls gate 8. Third and fourth demodulators are also included, the third demodulator (50) receiving inputs from adder 3 and 90 degrees phase shifter 11, and the fourth demodulator (51) receiving inputs from subtractor 4 and subcarrier oscillator 9; the third and fourth demodulators thus produce substantially no outputs for correct phase of generator 14, but outputs for incorrect phase of generator 14. The outputs of the third and fourth demodulators are fed via respective threshold detectors (52, 53) and a second OR gate (54) to the second input of the differential circuit (55).

A high polymer sponge of low specific gravity is impregnated with priming composition dissolved in its proper solvent and the sponge is then dried, leaving the priming composition dispersed throughout the sponge. The sponge may be of synthetic resin sponge, viscose sponge or acetate sponge, such as polyurethane, polyethylene polystyrol, polyvinylchloride, phenol and polyether &c., or any similar substance. The priming composition may be lead styphnate, tetracene, D.D.N.P. or mercury fulminate &c., which may also be mixed with potassium nitrate, chlorate or perchlorate, or barium peroxide. Five detonators using such priming sponges are described. In Fig. 1, a capsule 4 holds the priming sponge 10 on to a priming charge 3 above the base charge 2 and the detonator is contained within the shell 1. The detonator in Fig. 2 has a priming sponge 10 containing a large amount of priming charge compressed on to the base charge 2 by the capsule 4; such a priming sponge will detonate where it would only ignite if not compressed. Either detonator may be used with a safety fuse or with an electric bridge wire set in the sponge. An instantaneous electric detonator has a bridge wire in contact with a priming sponge above a priming charge and base charge. Fig. 5 shows a delay electric detonator in which a primary charge 3 is compacted by a capsule 4, the firing of the delay element 8 being ensured by the priming sponge 10 above it. Powdered priming composition 12 is fired in space 13 by bridge wire 5 connected to leg wires 6 passing through plug 7.

Sheet materials, such as wire or textile cloth and tissue paper, which by nature contain regularly spaced apertures, is illuminated by a beam of light arranged at such an acute angle to the material that the beam will not pass through the regularly spaced apertures but will pass through any unwanted apertures of a larger diameter. In the embodiment the sheet material continuously runs over one roller and under a second roller and a linearly extensive beam of ultraviolet light is directed at an acute angle on to the material between the rollers, any light passing through the larger holes reaching a photo-cell. Creases or lumps in the material can be detected, since as they pass over the rollers the plane of the illuminated material alters and light passes through all the holes.

Apparatus for determining the internal pressure of a tyre 1 comprises means for determining a value dependent on the load on the tyre, means for determining a value dependent on the contact area between the tyre 1 and a base 2 and means for determining the pressure from these values. In one embodiment, Fig. 1, the load is measured by means of a displaceable base 2 connected through a lever 6 piston 9, piston 13 transfer lever 14 and transfer rod 21. The contact area is determined by the fluid displaced from within an elastic pad 25. This displacement operates a piston 28 to displace rod 21. Displacements of rod 21 due to load and contact area measurements are transmitted to a pivoted operating lever 15 to move a displaceable rack 17 to actuate a pointer 20. A dial may be provided, Fig. 7, which is divided into four quadrants and has lines 56, 57 to indicate the highest and lowest permissible pressures for each tyre. Alternatively the contact area value may be determined by a pad of hollow units, Fig. 2, between a resilient layer 44 and a solid base 46. In another embodiment, Fig. 5, the base comprises two condenser plates 32, 33 with a layer of resilient dielectric 34 between them. When a tyre 49 (Fig. 6) is located on the base, the dielectric is compressed and the capacitance increased by an amount approximately proportional to the area of contact, measured by the potential across the plates 32, 33 with constant current. The load is measured at 35 by a piezocrystal 35 or differential transformers 54, and the two signals are combined in a wattmeter-type instrument 40.
