Title: Improvements in and relating to electric press-button operated switches
IPC: H01H13/72
Filed: 1948-03-24
Abstract: 641,515. Keyboard switches; switches held set and freed mechanically. WALTER INSTRUMENTS, Ltd., NOAD, J. E. G., and ARMSTRONG, C. J. March 24, 1948, No.. 8704. [Class 38(v)] A press-button controlled switch e.g. a tuned circuit selector switch for a radio receiver comprises spaced, parallel insulating plates 5 corresponding to the number of tuned circuits and carrying angularly-disposed radial contacts. Discs 16, 17 keyed to bushes 14 rotatable on a shaft 13 passing through the plates, are disposed on each side of each plate and carry the moving contact bars 18 projecting therethrough. Some of the contacts 8 are spaced from the plates 5 at their inner ends 12 and extend over the discs to engage selected contact bars 18 and the ends 11 of the remaining contacts 8 lie close to the plates and contact the inner ends of selected contact bars 18. The discs are rotated by arms 19 engaging slidably-mounted bars 22 carrying push-buttons 24, whereby any selected bar may be moved against a return spring 25 to rotate its related discs 16, 17 through the angular distance between two adjacent contacts 8 to switch in a particular tuned circuit. The bars 22 are retained set by a spring-pressed latching rod 30 engaging notches 34 therein. The rod 30 extends transversely to all the bars which also have cams 35 so that before engaging the notch in a particular bar, the rod is lowered by the cam thereon thereby disengaging it from any previously-set bar which is then returned by its spring 25. A " cancellation " bar 36 is also provided whereby the rod 30 may be disengaged from any pre-set bar to cut-out all the tuned circuits.

Title: Improvements in apparatus for measuring thicknesses
IPC: G01B7/02
Filed: 1946-03-22
Abstract: 629,648. Inductance and capacitance rneasurements. JACOT, G., and MONTI, J. March 22, 1946, Nos. 8940 and 8941. Convention dates, May 15, 1945, and Oct. 24, 1945. [Class 37] [Also in Group XIX] In a thickness-measuring device a comparator F is formed with a condenser C. B. so that as the rod A of the comparator is moved according to the thickness of a test specimen in place of a standard specimen E the capacitance of the condenser C, B is varied and disturbs the resonant condition in a pentode crystal oscillator. A compensating linear variation condenser C<SP>1</SP>, scaled in fractions of a millimetre, is adjusted to restore resonance and therefore indicate the thickness of the test specimen. The condenser C, B consists of a tubular plate C secured to the rod A so that as the latter is moved the plate C moves within the bore of a fixed tubular plate B. In setting up the device for operation the condenser C<SP>1</SP> is adjusted so that it reads according to the thickness of the standard specimen E with milliammeter I indicating resonance. The provision of condenser Cn, adjusted to neutralize the internal capacity of pentode R, ensures greater exactitude in the resonance adjustment. With the test specimen superseding E the condenser C<SP>1</SP> is varied until milliammeter I indicates the re-establishment of resonance. The Specification as open to inspection under Sect. 91 comprises also a modification, Fig. 2 (Cancelled, not shown), wherein the thickness index is a cyclometer geared to the movable element of C<SP>1</SP> and there is included a triode so connected in the oscillator circuit that when the resonance point is reached an electromagnet is energized to uncouple or lock the cyclometer gearing. This subject-matter does not appear in the Specification as accepted.

Abstract: 861,124. Magnetic pulse-gating circuits. STANDARD TELEPHONES & CABLES Ltd. March 22, 1957 [March 23, 1956], No. 9150/56. Class 40 (9). In a magnetic gate comprising a core having a rectangular hysteresis characteristic, input pulses are applied to one or more windings A and bias and control pulses to a winding B, the input and bias pulses being applied simultaneously and having opposite magnetizing effects so that a core is switched from one remanent state to the other only when input pulses are absent. Each bias pulse is immediately followed by a control pulse of opposite polarity which restores a switched core to its initial remanent state, the magnetization reversals inducing outputs in an associated output winding C. The sequence of pulses applied to windings A and B, and the induced outputs in winding C are shown in Fig. 4. An AND gate is described, Fig. 2 (not shown), in which four input windings A and the bias/control and output windings B, C are associated with an apertured core which may comprise an element of a multi-apertured ferrite block as described in Specification 760,048, outputs being induced only when input pulses to all four windings are simultaneously absent. An OR gate is shown in Fig. 5 comprising cores 10, 11, 12 having common bias/control and output windings B, C and individual input windings A1, A2, A3, outputs being produced when one or more input pulses are absent. A two-out-of-three gate having input windings A1, A2, A3 common to pairs of cores 5, 6, 7, is shown in Fig. 6. A modified AND gate with two inputs A1, A2 is also described, Fig. 7, in which an inhibit winding I, when energized, neutralizes core switching by the bias. Specification 760,047 also is referred to.

Abstract: 1,265,493. Texturising yarns. ARTOS DR.- ING MEIER-WINDHORST K.G. 20 Feb., 1969 [21 Feb., 1968; 19 March, 1968], No. 9268/69. Headings D1F and D1P. A process for texturising endless yarns such as spun cables, continuous filaments and spun yarns, of synthetic fibres comprises heating the endless yarn by a heat treatment in a heated liquid comprising a water soluble inert solvent at normal atmospheric pressure, or an aqueous solution at higher pressure, to a temperature in the softening range of the fibre material and subjecting the endless yarn while in a softened condition to a texturising deformation. The fibres may be of polyamide, polyester or polyacrylonitrile. The texturising deformation may be effected before, during or after the liquid heat treatment and may be effected by combined thermodynamic and turbulence dynamic treatment with steam or hot-air, by passing water coated endless yarn into the heated water soluble inert solvent to develop steam in the immediate vicinity of the endless yarn or by mechanical means. The high temperature liquid bath may contain further treatments for the endless yarns such as to improve dye receptivity, weather-resistance, and/or dispersion of electro static charge, and/or dyeing. The process may be followed by cooling then a washing treatment in several steps in which the washing water flows counter to the endless yarn which simplifies solvent recovery, and finally drying.
