Title: Improvements in or relating to electrical resistors and other electrical circuit elements
Inventor: LORO ALBERTO
IPC: H01B1/00
Filed: 1955-07-27
Abstract: 798,696. Ornamenting. PLANER, Ltd., G. V. Oct. 24, 1956 [July 27, 1955], No. 21745/55. Drawings to Specification. Class 93 [Also in Group XXXVI] An electric circuit component such as a resistor is formed by coating an insulating base with a conductive material parts of which are then removed to form a given pattern by treatment with an abrasive material in a liquid or fluid medium. In the application to a resistor a flat glass plate is coated with a paint comprising organic compounds of gold and platinum for example by a spinning method, the plate is then dried and a film of bichromated glue is applied over the coating and dried. The coated plate is then exposed to ultra-violet light in contact with the prepared negative of the desired resistance pattern the image so formed is developed in cold water and the plate stoved. The exposed unwanted areas of the metal film are then removed by gently wiping the plate with a liquid suspension of a fine abrasive powder for example chalk dispersed in propyl alcohol or alumina or silicon carbide dust in water or other liquid medium. After removal of excess abrasive material the remaining glue "resist" may be removed by immersion' in chromic acid followed by rinsing in water and firing. In place of the method of forming a glue "resist" the pattern can be applied by other methods such as by silk screen printing or spraying through a stencil the "resist" may subsequently be removed by chemical means or by dissolution in a solvent or by burning off. Instead of a flat plate type resistor a cylindrical filled type resistor may be used the film being then in the form of a helical band around an insulating cylinder. An inductive element may be made by the production of a spiral pattern of a conductive film on the insulating base. In a further modification the unprotected portions of the metallic film are removed by mechanical abrasion with the use of an abrasive powder suspended in a liquid medium the units being tumbled or agitated, for example, in a tumbling mill.

Filed: 1947-08-08
Abstract: 634,338. Helicopters. AUTOGIRO CO. OF AMERICA. Aug. 8, 1947, No. 21888. Convention date, Dec. 4, 1941. [Class 4] In a helicopter of the type having an airscrew offset to one side of the longitudinal centre line of the aircraft, the pitch of the rotor and airscrew blades is controlled by governor devices responsive to the speed of rotation of the rotor and airscrew respectively, the equilibrium settings of the governors being independently regulated and the governor for the airscrew preferably being coupled to the rudder control system. An engine 13 drives the rotor hub shaft 2 through a controllable clutch 14 and gears 12; 11, 7, 6 and drives the airscrew 15 through gears 12, 11, 17, 20, 19 and a pitch control mechanism 24. A sliding sleeve 41 fits over the hub shaft 2 and is provided with a spherical seating 40 for a swashplate 39 having arms 38 each coupled to a blade pitch control arm 5 by a link 37. The lower end of the swashplate is provided with a known type of cyclical pitch control mechanism 39a. For collective pitch control the lower end of the sleeve 41 is provided with a bearing ring 44 to which is pivoted one end of an arm 42, mounted on a rigid pivot 43 and geared at 46, 47 to a reversible electric motor 49. A governor 52 is driven from the gear 6 and controls one end of an arm 56, mounted on a fixed pivot 57 and formed at its other end into a contact 58 for engagement with other contacts 59, 60, the whole acting as a reversing switch for the motor 49. The spacing between the contacts 58, 59 and 60 is sufficient to permit a limited range of rotor speed without actuation of the pitch change motor 49. Limit switches 66, 67 and 69, 70, actuated by the sector 46, are provided to control the maximum and minimum pitch settings. To control the airscrew blade pitch a hydraulic governor 21 is supplied with engine oil by a pipe 27 and is connected to the pitch-changing mechanism 24 by pipes 25, 26. The governor is driven by gears 22, 23 and its setting is adjusted by a pulley and belt control 28, 29, 30 connected to the rudder bar 31 which also controls the movement of the rudder 35. By this means the yawing control effected by an increase or decrease of the thrust of the offset airscrew 15 assists the control effect of the rudder 35. Specifications 393,976 and 410,532 are referred to.

Title: Improvements in or relating to the coating of glass articles
IPC: C03C17/00
Filed: 1967-05-11
Abstract: 1,208,122. Coating sheets of glass. PILKING- TON BROS. Ltd., C. R. BAMFORD, W. J. R. MERREN and G. SHEPHERD. 22 March, 1968 [11 May, 1967], No. 21984/67. Headings B2E and B2L. A uniform film is formed on the surface of a sheet of glass by immersing the sheet in a coating liquid, locating the sheet in the liquid, and gradually lowering the level of the liquid about the stationary sheet at a rate such that the liquid meniscus sweeps down the surface of the sheet leaving a continuous static and optically uniform film of the coating liquid on the surface of the glass as the level of the liquid recedes. The level of the liquid is lowered at a constant rate controlled to avoid turbulence of the liquid meniscus thereby leaving a uniform film of liquid on the glass surface, where a part of the surface of the glass is to remain uncoated, that part is treated with an agent, e.g. a waxy substance, which renders the surface non-wettable by the coating liquid. The coating liquid may be an aqueous solution or a solution in an organic solvent of an organic compound, e.g. an organic compound of silicon or zirconium, water-soluble compounds of cobalt, nickel, manganese, iron, copper, silver or tin. Apparatus for producing the uniform film on a surface of a glass sheet comprises a tank for holding a coating liquid, means for locating the sheet in the tank so as to be completely immersed in the liquid, means for gradually lowering the level of liquid in the tank through an outlet at or adjacent the bottom of the tank, and a pump for recirculating the liquid to the tank when the coated sheet has been removed from the tank. The apparatus may be for producing a uniform film on the surface of glass sheets wherein the tank is in the form of a deep trough for receiving the sheets, a frame for locating the lower edges of the glass sheets which is mounted in the bottom of the trough, and the sides of the trough converge towards the bottom of the trough at an angle such that there is a constant rate of fall of the liquid level in 'the tank when the outlet is opened.
