Filed: 1932-05-26
Abstract: 402,400. Fused silica. CLARK, F. L., Winnington Hall, Northwich, Cheshire, and IMPERIAL CHEMICAL INDUSTRIES, Ltd., Millbank, London. May 26, 1932, Nos. 14952 /32, 15128/33, and 15129/33. [Class 56.] A process for making an article of vitreous silica consists in shaping the article by casting a mixture of silica and water the pH valve of which lies between 1.1 and 11.5, or by pressing or moulding a composition obtained by dewatering such a slip, and then heating the shaped body to the temperature at which the silica changes over to the vitreous state. Preferably, a slip containing about 40 per cent of silica is prepared by mixing very finelydivided quartz with water, and after adjusting its pH to a value between 5 and 19, the slip is cast in a suitable porous mould. The cast article is dried at about 100‹C., and is then placed in a furnace and heated to a temperature at which vitrification occurs. In a modification, fused silica particles may be used as the initial material, the heating being carried to the point at which the particles are fused together, only the surface being vitrified to form a glaze. Instead of casting the slip, it may be filtered or otherwise dewatered, and the resulting wet solid material used as a binding agent for other silica particles, which may be coarser. The mixture thus prepared may be moulded to the desired shape, if necessary with the addition of a binder such as benzyl cellulose, and the article is dried and heated as before.

The phase of the unbalance of a rotor 1 (Fig. 1) is determined by feeding the unbalance signals from an electrical pick-up 2 through a phase-splitter 5, to give A.C. voltages at 90 degrees to each other, which are taken to the plates of a cathode-ray tube in an oscillograph 7 to give a circular trace, and also through a pulse-forming unit 6 which generates a cyclic, short duration pulse which is fed to the grid or cathode of the C.R.T. to brighten or blacken the trace for the duration of the pulse, a reference pulse being obtained from a coil 8 with permanent magnet core due to the recurrent passage of a small projection 9 of magnetic material attached to the rotor 1, whereby the position of the unbalance mass with reference to the position of the magnetic material 9 can be seen on the C.R.T. trace. The magnitude of the unbalance mass is indicated on a meter 4 receiving the amplified signals from the pickup 2.

Abstract: 632,366. Radio direction-finding. STANDARD TELEPHONES & CABLES, Ltd. May 17, 1946, No. 15011. Convention date, May 21, 1945. [Class 40 (vii)] In a radio direction-finder of the type wherein the spot of a cathode-ray tube is deflected in a circular path in synchronism with the rotation of a rotating directional aerial and controlled by the received signals to trace out a pattern which indicates the direction from which signals are being received, means are provided for converting the output of the receiver into sharp unidirectional pulses corresponding to instants of null-reception and for applying these pulses to deflect the cathode-ray beam radially so that the direction of reception is indicated by a radial linear trace. The aerial 1 is continuously rotated about its vertical axis by the driving means 3 which also drives the deflecting coil 12 in a rotary motion about the cathode-ray tube 13. The output from the receiver 5 which comprises a full-wave-rectified sine wave is applied to the " clipper " circuit 7 which passes the cusps of the rectified sine wave so as to deliver pulses at twice the frequency of the aerial rotation. The pulses are amplified at 9 and applied to a D.C. restoration circuit 10 which provides positively directed pulses, the peaks of which are at zero potential. The pulses are then applied to the deflecting coil 12, through the amplifier 11, which is cut off during the negative base portions of the pulse signal and which provides a predetermined deflection when the input potential rises to zero, so that a linear trace is obtained whose angular coordinate indicates the direction of reception and whose length is independent of the amplitude of the received signal. To eliminate indications caused by false nulls produced by signal modulation there is provided a tuned amplifier 15 which is tuned to twice the frequency of the aerial rotation, and to which are applied the pulses from the amplifier 9. The output of the amplifier 15 is a sine wave which is " clipped " at 16 and 18 to provide broad pulses which encompass the narrow, direction-indicating, pulses. These pulses are applied through the D.C. restorer 20 to brighten the trace of the cathode-ray tube during the application of the narrow pulses. In another embodiment, Fig. 3 (not shown), the output from the receiver is applied to a tuned amplifier which delivers a sinusoidal output. This is clipped to provide narrow pulses which are used as before to deflect the cathode-ray beam and also to brighten the tube trace. Specification 494,263 is referred to.

Convention date, June 2, 1931. [Class 40 (iv).] In a brush-choosing selector in which a preliminary setting movement of the brush-carrier selects a brush-set for tripping, the actual tripping action is effected by a control-switch member of sequence-switch or side-switch type. The invention is described with reference to a panel selector comprising a brush-carrying plate B sliding in guides 24 on the flat bank K and coupled to a driving member 33 sliding on a flat plate 32. The downward movement takes place by gravity under control of a stop magnet 40 and friction brake 42, and the upward restoring movement is effected by a fluid-pressure motor R. An auxiliary switch member 43 controlling contacts such as off-normal contacts 49 and attached to the driving member 33 by a spring 44 remains stationary during the brushchoosing movement but is positively coupled to the member 33 either by the engagement of a pawl 47 with a rack 48 on movement of the control switch 34 or subsequently by the guide 35 striking a projection 46. The control switch 34 consists of a sliding rod carrying contactcontrolling cams 59, 60 and is controlled by an escapement 55 actuated by a magnet 57. At the first operation of magnet 57 at the end of the brush-choosing operation the movement of lever 61 from under arm 63 frees pawl 47 to engage with ratchet 48 and at the same time a hook 69 causes a pivoted lever 66 to rock the shaft S whereby one of the pins 28 actuates the trip lever 29 of the selected set of brushes. A pointer 52 on the auxiliary switch member 43 co-operates with scales 50, 51, on the driving member 33 and on the baseplate 32, respectively, to give a two-co-ordinate indication of the position of the brushes. During the restoring movement of the driving member 33, a pin 73 engages a projection 65 to raise the control switch 34. Specification 275,255, [Class 40 (iv), Telephones &c.], is referred to.
