Title: Coaxial tube arrangements
IPC: F16L59/14
Filed: 1973-01-31
Abstract: 1400652 Insulated metal pipes KABEL-UND METALLWERKE GUTEHOFFNUNGSHUTTE AG 31 Jan 1973 [3 March 1972] 4979/73 Headings H1A and A4D In a coaxial tube arrangement of at least two metal tubes, e.g. for super-cooling a cable in the inner tube 1, at least two strips of super-insulating material 4 are helically wound on the inner tube in alternating winding directions and with spaced turns so as to leave holes at the inter-sections of the strip edges. The inner tube 1 is supported by elements 5 which pass through these holes. As shown, the elements 5 are attached to the inner tube 1 by eyelets 3 in a helically wound strip 2. Sleeves are placed over the elements 5, which may be filaments of synthetic material, to protect them whilst the layers of super-insulation 4 are wound over the strip 2, and are then removed. Successive layers of super-insulation 4 are wound from strips of different widths, the ratio of the strip widths being either a whole number or not. The gap between adjacent turns of the same strip is between 0À5 and 4 mm. and preferably 1 to 2 mm. The support elements 5 are attached to a member 6, which may be helical or a series of connected rings, which is then received within the outer tube, the space between the tubes then being evacuated.

Abstract: 1,253,765. Sb and Bi diffusion into Ge and Si. SIEMENS A.G. 3 Feb., 1970 [4 Feb., 1969], No. 4993/70. Heading H1K. Antimony and/or bismuth are diffused into a silicon (1100-1300‹ C.) or germanium (700- 900‹ C.) body by heating the body in an atmosphere containing or consisting of one or more M(OR) 3 , where M is antimony or bismuth and R is an alkyl or aryl group with not more than 10 carbon atoms. Examples are the methoxy, ethoxy and phenoxy stibines/bismuthines. Part of a nitrogen or argon stream may be passed over or through these liquid dopants and, if it is desired to also provide a doped vitreous oxide on the semi-conductor surface, the carrier gasdopant stream may be mixed with oxygen and/or nitric oxide either within or immediately adjacent the diffusion chamber. This chamber is heated in a single zone tubular furnace. The method may be used to provide buried regions from which little diffusion occurs during the epitaxial deposition which provides the overlying semi-conductor.

Filed: 1925-02-25
Abstract: 252,274. Horstmann, S. A., and Rooke. J. W. Feb. 25, 1925. Turning-gear.-In a starting-device for internal-combustion engines, a dog clutch member 15 driven from an electric motor engages a dog clutch member 18 formed on a floating element 10, the inclined faces of the members 15, 18 moving the element 19 .axially into engagement with a clutch member 20 on the engine shaft 12. As shown, the members 19, 20 form a cone clutch and the clutch member 15 is mounted on a freely mounted worm wheel 10 in engagement with a worm 4 on the shaft 3 of the starting motor, the worm being movable axially against a spring in case the engine turns backwards while the clutch 19, 20 is in engagement.

Title: Improvements in or relating to hydraulic measuring systems
Inventor: GAHR SVERRE
IPC: G01F3/38
Filed: 1960-02-13
Abstract: 890,978. Liquid meters. JOTUL A.S. Feb. 13, 1960, No. 5206/60. Class 69 (1). A measuring tank has inlet and outlet valves opened alternately when lower and upper liquid levels are reached in the tank by operation of two bi-stable mechanisms, each of which comes into either of its stable conditions with quick action from the other stable position, one mechanism being operated by a float and in turn actuating the other mechanism, which actuates the valves. The valves 4 and 5 have elongated stems 10 and 11 which pass freely through the float 20 and through a wall 12 above the float chamber. Pivoted above the wall 12 are two tiltable shoots 14 and 15, in each of which rolls a weight 16, 17 in the form of a roller. The shoot 15 has lugs 18 which extend above and below the shoot 16 and a bracket 25 in which rests the end of a cranked rod 21 on which the float 12 can move freely between stops 22 and 23. The shoot 14 rests either on the rod of the outlet valve 5 or on the rod of the inlet valve 4, thereby closing the valve in question. When the liquid in the float chamber reaches a predetermined level the float raises the stop 22 thereby causing the rod 21 to raise the shoot 15 so that the weight 16 rolls from the outlet valve end to the inlet valve end and tilts the shoot sharply. The lugs 18 cause the shoot 14 to behave similarly, closing the inlet valve and opening the outlet valve. When the liquid falls sufficiently the float contacts the stop 23 and the process is reversed. A small tank with a shut-off valve 7 operated by a knob 9 serves as a reservoir whilst the chamber refills. Specification 241,378 is referred to.

Abstract: 843,441. Clutches. VINCENT ENGINEERS (STEVENAGE) Ltd., and VINCENT, P. C. May 16, 1957 [Feb. 20, 1956], No. 5242/56. Class 80 (2). [Also in Group XXVII] An automatically engageable and disengageable ratchet clutch particularly for a hand starter for a small I.C. engine, comprises a ratchet-toothed clutch member 25 secured to a hand-operated cable drum 32, and advanced axially into engagement with a complementary ratchet-toothed clutch member 51 fast on an engine shaft 12, by action of the initial turning movement of the cable drum on two control sleeves 17, 22 in helical interengagement as by screw threads or a stud 20 on one, engaging a helical slat in the other, one 17 of the control sleeves being fixed, while the other 22 is in frictional engagement with the toothed clutch member 25, as by end pressure of a wavy spring 29, and moves axially with the said clutch member. Thus when a handle 35 is pulled to start the engine, a cable attached thereto turns the cable drum 32, which first engages the ratchet clutch 25, 51 and then through the latter turns the engine shaft 12, the friction connection between the outer control sleeve 22 and the clutch member 25 slipping. When the engine starts, the clutch teeth are disengaged by ratchet action, and release of the handle 35 permits a spiral spring 36 to wind back the cable drum 32, retracting the clutch member 25. Seals 31, 53 retain lubricant.

Abstract: 312,207. Cook, G. H. Feb. 20, 1928. Joint-making packing. - In making jointmaking packing, brass or other wire is fed, together with a composition consisting of, for example, asbestos fibre and indiarubber, between rollers, so that the wire is incorporated in the sheet. Indiarubber mixed with asbestos fibre is worked up into a plastic mass, a quantity of rubber solvent being incorporated. The mass is then fed between a pair of heated rollers preferably disposed side by side.

Convention date, March 3, 1934. [Class 35] Coils; rotary machines; field magnets, dampers on poles of.-In a compound-wound starting motor for internal-combustion engines, the field magnets comprise pole cores G carrying polepieces L around which are wound the coils of the series winding K so as to extend closely around the periphery of the armature F in approximate continuation of the pole face. The coil sides are secured by metal bands M fixed to a supporting body N adjustably held in the casing J by bolts O. The bands M are of non-magnetic material of high specific resistance such as Constantan or Cekas, and an insulating spacer Q is inserted between the inner portion of the band and the coil side. To obviate the effect of electromagnetic forces on the curved sides V of the coils, wedge-shaped members R located equidistantly about the axis are inserted between adjacent coils and are secured to the casing by bolts S. The coil sides may bear directly against the sides of the polepieces, or if tapered poles are employed in order to reduce leakage, non-magnetic filling members T may be fitted as shown in connection with the left-hand pole. If with, the described arrangement the speed of the motor is insufficient to start the engine, a shunt circuit for the series winding may be temporarily closed. The motor may function as a generator in which case the series winding is automatically short-circuited to function as a damping winding.
