Filed: 1921-11-26
Abstract: 187,870. Clements, G. F. Nov. 26, 1921. Cleaning internally. non-rotary appliances for. - Relates to tube scalers of the type comprising striker pistons reciprocated by compressed air, and consists in closing the ends of the bushes or bores in which the pistons reciprocate by a enclosing sleeve which replaces the screwed plugs ordinarily used. In the form shown in section in Fig. 3, the tube through which the compressed air is supplied is replaced in part by a member 1, in which the piston bores 3, are arranged in staggered relationship. The bores are closed at one end by the sleeve 9 which is held against rotation by a slot 16 engaging a pin 15 in the part 1. The air is supplied through the connection 4 and passes to the individual cylinders by way of a helical groove 7 and communicating holes 8 around and in the member 1 respectively. The outer face of the members may be slightly conical and the sleeve similarly faced, so that an air-tight joint between the two may be made by adjusting the nut 12. The member 1 may have a conical or stepped formation, the use of the sleeve in lieu of the plugs permitting of this, and the pistons may be arranged either at right angles to the conical wall or to the axis, as de. sired.

Patent GB-1352779-A (GB)
Title: Method of manufacturing semiconductor devices
IPC: H01L21/74
Filed: 1971-07-07
Abstract: 1352779 Semi-conductor devices PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 7 July 1971 [10 July 1970] 31842/71 Heading H1K A semi-conductor zone 24 is formed in a semi-conductor body by doping a surface part of the body through a mask, increasing the size of the aperture in the mask and oxidizing the now exposed semi-conductor surface. As well as forming an oxide layer 23 at least partly inset into the semi-conductor body the heating required for the oxidation process also drives the dopant further into the body to form the zone 24. A recess may be formed in the body prior to oxidation in order that the upper surface of the oxide 23 may be substantially flush with the rest of the device surface. This recess may be formed by etching through the enlarged mask aperture or by oxidation through the aperture followed by removal of the oxide. As shown the invention is used for device isolation in a Si integrated circuit including a transistor and a resistor. The devices are formed in island-shaped portions 22 of an N-type epitaxial layer on a P-type substrate 21, and are laterally isolated by the combination of the inset oxide 23 and the P-type zone 24. Fig. 13 (not shown) illustrates a modification of this structure in which a P-type isolation zone (54) formed in accordance with the invention beneath an inset oxide layer (55) extends down to meet a P-type buried layer (53), thereby isolating an island-shaped region of an N-type epitaxial layer (52) deposited on an N-type substrate (51). The invention is also applicable to the manufacture of a target plate for a T.V. camera, the plate comprising an array of PN mesa diodes and an N<SP>+</SP> zone (5), Fig. 6 (not shown), formed in an N-type substrate (1) beneath an inset oxide layer (4) providing a means for preventing inversion channels, etc., forming between adjacent diodes. SiC is also referred to as a suitable semiconductor material, and ion inplantation or diffusion from a doped oxide layer may be employed to dope the body. The dopant used may be an acceptor or donor or may be a lifetime-determining impurity. Initial introduction of the dopant may be effected through an area of the mask which is permeable to the dopant, rather through an actual aperture.

Filed: 1926-12-17
Abstract: 279,274. Marks, E. C. R., (Kemet Laboratories Co., Inc.). Dec. 17, 1926. Vacuum tubes. - Thorium-tungsten, thoriummolybdenum. and thorium-tungsten-molybdenum alloys, for use in electron-emitting devices, are made by heating in hydrogen a compacted mixture of thorium hydride and the other metal or metals to a temperature sufficient to decompose the hydride, and further heating in hydrogen, to sinter and complete the formation of the alloy. For example, a mixture of thorium and tungsten powders may be pressed into a rod and heated in hydrogen to 1300-1450‹ C. for about half an hour after which the rod is pushed into a watercooled portion of the furnace and rapidly cooled in hydrogen. The product is finely powdered and again pressed into a rod which is heated in hydrogen to 1300-1450‹ C. and cooled. It is then further heated in hydrogen by passage of an electric current. The alloys may contain for example 10 per cent of thorium and 90 per cent of tungsten, or 0.5-.5 per cent of thorium and the remainder molybdenum, or up to about 5 per cent of thorium, 20-40 per cent of molybdenum, and the remainder tungsten.

The leading-in wires may be formed by helices 9, 10, Fig. 1, of stout tungsten wire which are welded at one end to metal rods 7, 8 and bent at right-angles along their length, the ends 11, 12 of the helical filaments being slid through the helices 9, 10 and welded to the rods 7, 8. To increase the cross-section of the coils acting as leading-in wires and electrodes a mandrel 19 of tungsten wire is inserted into each of the end portions 11, 12 and their associated coiled helices 13, 14, so that only the portion 15 is without a core. This latter portion is disposed substantially at right-angles to the helices 13, 14 and may be bent into S-shape, with additional supports 16, 17 of thin molybdenum wire fastened to an insulating body 18 mounted between the rods 7, 8. The single turns of the double coils 13, 14 may be spaced uniformly, as shown in Fig. 2, but are preferably in contact at the upper portions of the coils to provide a larger surface for the arc discharge. In a modification the end portions 12, Fig. 4, of the double coils are welded directly to a bent rod 20 mounted on the metal rod 8. Preferably the bulb 1 contains a quantity 21 of mercury or an amalgam.

A balanced flue unit air heater comprises an inner hollow heat exchange panel 15 within an outer hollow panel 24, a burner 21 being mounted within the inner panel 15 and close to the bottom thereof, the inner panel having a combustion air inlet 16 and a flue gas outlet 17. A crossflow fan 30 is located above the outer panel, which fan draws in air through an air inlet (11), Fig. 2 (not shown), in the top of the outer casing (12) of the unit and delivers it through an inlet 29 into the space between the inner and outer panels, where it is heated indirectly by the flue gases in the inner panel 15 before being delivered into the space to be heated through an outlet (13) in the base of the unit. A centrifugal fan 50, coaxial with the crossflow fan 30 and driven on a common shaft therewith, draws air from the atmosphere into a chamber 55 and delivers it to the inner panel through a flexible duct 56 and inlet 16. The flue gases escape through the outlet 17 and through a tube (83), Fig. 3 (not shown), coaxially within the combustion air inlet (75) to the fan 50. A single control 96 is provided which adjusts the fuel supply rate, controls an electric circuit for the motor 47 and is designed to ignite the burner. Fuel initially flows only to a pilot burner 114 which is ignited by an igniter 107 comprising an ignition coil heated by a pulse from a transformer operated by the control 96, the heat from the pilot operating a valve controlled by a mercury tube 115 and allowing fuel to flow to the burner 21. On failure of the motor, combustion air ceases to flow and the burner is extinguished.
