Title: Improvements in and relating to sparking plugs and methods of making the same
IPC: H01T13/32
Filed: 1920-01-16
Abstract: 153,808. British Thomson - Houston Co., (General Electric Co.). Jan. 16, 1920. Sparking-plugs are made by packing a powdered insulating-material, such as fused magnesia, quartz, mica, or alumina. around a rod 18 placed centrally in a tube 5, and swaging or drawing down the whole until the powder is compressed into a hard, solid mass. Insulating-heads 7, 8, which may be of porcelain, are secured to the ends of the shell by caps 11, 14, in order to prevent the insulation from crumbling, and the heads may have ribs 9 in order to increase the surface in contact with compressed insulation. The manufacture is carried out with a long tube and central rod, the whole being cut into suitable short lengths after swaging.

Title: Remote angle measurement
IPC: E21B47/022
Filed: 1972-01-12
Abstract: 1410051 Measuring angles electrically M K RUSSELL and A W RUSSELL 4 Jan 1973 [12 Jan 1972] 1537/72 Heading G1N A transducer arrangement for providing signals indicative of angles of pitch and roll, i.e. angles about perpendicular axes for the inclination of the head of drilling tool in a borehole comprises, Figs. 1 and 5, a mass 2 which under gravity causes a rod 3 to bend causing variation in two pairs of differential capacitors formed by the body 2 with four fixed capacitor plates 6, the arrangement providing a signal whose amplitude is dependent on the pitch and whose phase depends on the roll. As shown in Fig.7 signals of A cos wt. and A sin wt. are fed to primary windings 33, 34 of transformers whose secondary windings are centre tapped to earth and connected to opposite plates 6a 6a, 6b 6b respectively. The output signal derived from the body 2 is given by A sin # sin (wt-#) where # is pitch angle and # is roll angle. This output is fed to phase locked loop circuit 38 which provides a squarewave constant amplitude signal with the same zero-crossing points as the input. This signal is used as a demodulating signal in 3 circuits. In circuit 40 it demodulates A sin # sin (wt-#) and yields after integration K sin #. In circuit 39 it interrupts the signal A cos wt. and after integration yields K sin #, whilst similarly in circuit 41 K cos # is obtained. A resolver gives # from K sin # and K cos #. Details of the transducer are provided Fig.6 (not shown), which disclose an arrangement wherein the mass 2 is oil immersed and a closed bellows is provided in the oil chamber to allow for thermal expansion.

Title: A New or Improved Process of Manufacturing Colour Leaves.
Inventor: IWATSUBO GOHEI
IPC: B44C5/06
Filed: 1917-02-02
Abstract: 109,205. Iwatsubo, G. Feb. 2, 1917. Bronzing and the like.-Colour foil for use in printing and other processes is made by immersing a roughened plate in a volatile solution of a solid, such as camphor, which will volatilize by heat, coating the plate with the colour, and heating the plate, whereby the volatilization of the solution separates the foil from the plate. A plate of tin, glass, copper, or other suitable heat-conducting material is roughened by sand-blast or otherwise and immersed in a solution of 15 parts of camphor in 100 parts of naphtha. The naphtha is then volatilized, leaving a deposit of camphor on the plate, which is then coated with a colour mixture composed of 100 parts of water, 10 parts gelatine, 5 parts of glycerine, 2 parts of syrup made of sugar and water, and a suitable quantity of colouring-matter. One part of starch is added to the mixture to render it impermeable to air, so that upon heating the plate, the volatilized camphor cannot pass through the foil and consequently tends to lift the foil and separate it from the plate. To prevent the volatilization taking place too readily, 2 parts of stearine may be added to the volatile solution.

A battery B is charged from an A.C. source a, b by way of a rectifying diode D 1 , a converter comprising a transistor Tr 1  and a transformer T having a primary winding nc in the collector circuit of the transistor Tr 1 , a feedback winding nb connected to the base of the transistor and a secondary winding ns the output of which is rectified by a diode D 2  to charge the battery. When the battery B is sufficiently charged the potential at the mid-point of a divider R 2 , R 3  becomes such that transistor Tr 2  turns on so turning on transistors Tr 3 , Tr 4 , the turn-on of transistor Tr 4  connecting the base of transistor Tr 1  to its emitter whereby the transistor Tr 1  ceases oscillation so terminating the battery charging process. The turn-off of transistor Tr 1  may be enhanced by connecting a diode in its base or emitter circuit and the connection of a diode between the emitters of transistors Tr 1 , Tr 4  prevents interaction between the A.C. source and the secondary side of the transformer T. If desired the converter may comprise a pair of transistors operating in a push-pull blocking oscillator mode. In order to provide full electrical isolation between the secondary and primary sides of the transformer T the connection between the transistors Tr 4  and Tr 1  may include a photo-electric element, an electromagnetic relay or a thermo-electric element. An indicatoring lamp may be provided to indicate that charging is taking place.

Jan. 21, 1959 [Jan. 22, 1958; Jan. 8, 1959], No. 2271/59: Classes 75 (1) and 75 (3): [Also. in Group XXVIII] A combustion apparatus comprises a rotary cup burner 3, a fuel oil pump 7, a fuel accumulator 17 disposed in the fuel supply pipe between the pump and the burner, a valve 18 for entrapping fuel under pressure in the accumulator when the pump is closed down and an electrical resistance 26 for igniting fuel supplied to the combustion chamber. 2 from the accumulator. The fuel pump 7, the rotarycup 3 and a fan 4 for combustion air are drivenby an electric motor 6. The-valve 18 is operated by a solenoid 19. When the burner is closed down the electric motor 6 and the solenoid valve 18 are de-energised simultaneously but the motor keeps on, running long enough to charge the accumulator 17 with fuel under pressure. At starting the solenoid valve 18 is first opened and the fuel in the accumulator flows from the stationary burner cup 3 into a groove 25 in the wall of the combustion chamber 2 and is .ignited by the resistance 26. The motor 6 is then started and the fuel thrown out by the rotating cup is ignited by the fuel burning in the groove 25. The fuel supply is controlled by a further valve 20 actuated by a variation in temperature or pressure. The accumulator 17 consists of a diaphragm 22 and an adjustable spring 23 acting thereon. The pump 7 comprises a diaphragm 8 pressed by an adjustable spring 10 and actuated by a shank 9 engaged with a slanted disc 12 on the end of the shaft 5 of the electric motor. If the fuel pressure developed by the pump exceeds a predetermined value the diaphragm moves the shank 9 out of engagement with the slanted disc. In a modified arrangement the fuel pump comprises two spaced diaphragms of unequal diameters connected by a rigid spacer and actuated by a shank engaging a ball bearing mounted on an eccentric pin on the end of the motor shaft ; and the solenoid valve has its stem secured to the diaphragm of the accumulator and controls an outlet in the wall of the accumulator.
