Title: Improvements in or relating to bonded metal/glass-ceramic elements
Inventor: MCMILLAN PETER WILLIAM
IPC: C03C10/00
Filed: 1961-03-10
Abstract: To form a printed circuit panel, a metal component in the form of a thin metal foil is bonded to a flat plate of devitrified glass-ceramic or of a glass capable of controlled devitrification and the bonded element heat-treated to convert the glass to glass-ceramic.  The metal foil may be of copper or copper alloy, silver or silver alloy or nickel; the copper or silver may be coated with a thin layer of nickel and the copper or nickel given a thin layer of the corresponding oxide.  As described, the metal foil is pressed on the base of a mould, which base may be porous and the foil held by suction, and molten glass poured on the foil and either pressed by a die or rolled.  The mould is of cast-iron or steel so that the foil is not melted by the heat of the glass. The resulting element is annealed and heat treated to devitrify the glass, treatment for copper being in an atmosphere of nitrogen. The preferred glass composition is in weight percentages SiO2 50-80; PbO 0-30; Al2O3 0-3; ZnO 5-30; Li2O 5-15; B2O3 0-7; K2O 0-5; Na2O 0-5; P2O5 1-3.

Title: Improvements in or relating to the control mechanism of wireless receivers
IPC: H03J5/12
Filed: 1940-05-17
Abstract: 543,639. Wireless receiving apparatus. PHILIPS LAMPS, Ltd. (Naamlooze, Vennootschap Philips' Gloeilampenfabrieken). May 17, 1940, No. 8836. [A Specification was laid open to inspection under Sect. 91 of the Acts, Nov. 21, 1940. ] [Class 40 (iv)] [Also in Group XXXVI] In a wireless receiver having one or more switch assemblies for performing more than two switching operations by direct actuation by pushbuttons or by actuation by a motor controlled by push-buttons, each switch assembly is built up from two or more electrically connected switches which have fewer switching positions than there are switching operations. As shown in Fig. 1, a tuning condenser 4 can be connected to any of the four inductances 23 ... 26 by means of two coupled switches 14, 15 in series wifh a switch 16, these switches being connected to a pair of levers 12, 13. These levers and the condenser are actuated by screws 10, 11, 15 on a plate 3 when a push-button t attached to the plate is depressed. The adjustment of the screw 5 in the plate 3 determines the setting given to the condenser ; and the positions of the screws 10, 11 in one of the holes 6 or 7 and 8 or 9 respectively in the plate 3 determines the position of the switches and therefore the particular inductance connected to the condenser. These inductances may be for wave-range selection or for bandwidth adjustment. In another arrangement, Fig. 2, two switches 34, 35 are connected as shown between the inductances and the tuning condenser.

Filed: 1917-11-02
Abstract: 120,352. Wade, H., (Universal Winding Co.). Nov. 2, 1917. Winding-machines.-In cone winding machines, particularly of the dium type such as is described in Specification 120,261, the cone C is supported between arms A, B, pivoted eccentrically to one another and arranged one at each end of the cone with means to permit the tilting of the cone at its points of engagement with the arms. The arm B. Figs. 3 and 4, is pivoted on a rod T<1> supported in brackets 28 from a tie-rod T extending the length of the machine. The arms A are pivoted on studs 29 carried by the brackets 23 and comprise an arm 46 carried by a hub 40 on the stud, and an arm 46<1> pivoted to the arm 46 and controlled by a spring 49. A spring washer 45 bears on the end of the hub 40 to retard the movement of the arm A and to cause the apex of the cone C to bear with the necessary pressure against the drive roll. The hub 30 of the arm B is loose on the the rod T<1> and carries a projection 35 which is pressed by a spring 31 against a cam 34 fixed on the tie-rod T. As the cone grows and the arm B is raised, the cone is pushed by this arm slightly in the direction of its length towards its apex. A washer 37 held by projections 38 embracing the rod T is interposed between the spring 31 and the hub 30. The arm B carries a pivoted catch adapted to engage the tie-rod T to hold the cone out of engagement with the driving-drum, and also a weight to ensure the necessary contact between the cone and the driving-drum. The cone-holder is supported upon a ring 55, Fig. 2, carried by ball bearings 66 upon a stud 58 on the arm B. The ball bearings are interposed between the ring 55 and a sleeve 61 having convex ends to fit a concavity 63 in the arm B and the concave head 59 of the stud 58. There is clearance between the stud and the sleeve to allow the sleeve to rock slightly. The apex of the cone-holder fits in a cup 50 carried by ball bearings 52 in the arm A. A series of cone-holders is arranged on each side of the machine and the arms A, A<1> and B, B<1> for the two series are arranged in pairs as shown in Figs. 3 and 4. A suitable stopping-mechanism may be applied.

Filed: 1930-03-24
Abstract: 348,304. Tipping apparatus. ELLSON, B. E., Abford House, Wilton Road, Victoria, London. March 24, 1930, No. 9316. [Class 78 (iv).] In apparatus for hoisting and tipping wagons the hoisting rope is carried from the winch round a sheave on the tipping cradle, around sheaves on the hoisting table and is then anchored to the cradle. The hoisting rope A passes from the which B over a sheave C on the cradle D and around sheaves E on the table G to an anchorage H on the cradle. By winding in the rope the table is hoisted until the wagon contacts with a buffer bar O on the cradle. Continued winding causes the wagon to contact with a side buffer bar N and the cradle then rolls over to tip the wagon and discharge its contents. The table is fitted with uprights Q carrying rollers R engaging the rope to prevent swinging of the table. Specifications 291,489 and 339,064, [both in Class 78 (iv), Loading &c.], are referred to.

Abstract: 622,110. Coating optical lenses. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. March 27, 1946, No. 9411. Convention date, July 1, 1941. [Class 93] [Also in Group XX]  An aspherical surface is formed on the plane or spherical surface of a transparent plate by the uneven deposit by vapourization, sublimation or spraying of a transparent substance or a substance rendered transparent after deposit. As described the substance is evaporated from a filament 4 and reaches a glass plate 6 after passage through the apertures of a rotating shutter 9 which are of a size and shape to produce a deposit 16 having portions A, B, C. Suitable substances are calcium fluoride and quartz. Alternative magnesium or barium which are oxidized after deposition to give a transparent coating may be used.

Title: Improvements in or relating to piezo-electric substances
IPC: H01L41/18
Filed: 1928-03-29
Abstract: 311,055. Freedman, P., and Rickets, W. J. March 29, 1928. Television. - Substances possessing piezoelectric properties, and also in some cases the property of rotating the plane of polarization of light, are produced artificially from a dielectric material, preferably one with a high dielectric constant, and comprise a multiplicity of suitably orientated hemihedral crystals in close juxtaposition or embedded in a suitable medium. The dielectric may be composed wholly or partly of one or more waxes, hydrogenated fats or oils, or natural resins, either separately or mixed in suitable proportions ; or it may be composed partly of celluloid, vitreous material, or the like. Hemihedral crystal structure is obtained by incorporating one or more optically operative bodies, such as zinc oxide, neutral sulphates of cinchonine, or ouprein, dicamphahexandion, and dicamphahexandionperoxide or the optically-active substances present in the oils and resins can be relied upon. Crystal orientation is obtained (1) by depositing the crystals from a liquid under the influence of an electric field or (2) by depositing the crystals on an electrode from an electrolyte solution or (3) by precipitation from a saturated solution on cooling or evaporation or on addition of a precipitating agent or (4) by a mechanical process such as repeated rolling of the crystalline body. The artificial crystal may be used as a light interrupter in television and like systems.
