Title: Improvements in a method of manufacturing articles and threads of rubber
IPC: B29D99/00
Filed: 1933-11-25
Abstract: 430,982. Indiarubber threads. SCHULLER, H., 10, Zieglerg, MATZNER, E., 3, Sebastian Brunnerg, and KAILICH, A., 4, Lautensackgasse, all in Vienna. Nov. 25, 1933, No. 33025. Convention date, Aug. 1. [Class 70] Threads of rubber or similar material are made by depositing a rubber band, from a liquid containing rubber or the like, continuously on a moving support, such as a band, of the same or substantially the same width as the rubber band being produced and feeding the latter directly and continuously into a twisting device to form the thread. The band may be dried or vulcanized before entering the twisting device but only to such an extent as leaves it sufficiently adhesive to enable thread formation. In an apparatus described, an endless band 2 passes through a self vulcanizing rubber dispersion 4. The coated band then passes through a drier 6 and to twisting devices with grooved discs 8, which detach the rubber bands 10 and twist them into threads. The slot 5 of the container is provided with a packing. The twisting devices as well as providing rotation of the discs 8 also rotate as a whole about an axis coincident with the thread. The twist remaining in the thread is eliminated by suitable rotation of the winding device on which the thread is received after the twisting. The initial rubber band produced tapers towards the edges so that when it is twisted into a thread, the various layers lie closely together and no perceptible ridge is produced. Specification 431,031 is referred to.

Title: Improvements relating to the formation of p-n junctions in semi-conductor material
Inventor: GASSON DENYS BROMLEY
IPC: H01L21/00
Filed: 1957-10-25
Abstract: <PICT:0852749/III/1> <PICT:0852749/III/2> <PICT:0852749/III/3> <PICT:0852749/III/4> An NPN or similar junction structure is produced by locally melting a narrow peripheral region of a semiconductor bar containing both donor and acceptor materials with differing segregation coefficients, and maintaining the region near melting point for a period of minutes to allow diffusion to occur.  Fig. 1 shows a silicon or germanium bar 1 containing antimony and aluminium as impurities suspended in a r.f. heating arrangement consisting of coil 3 and concentrator 4.  A graphite cylinder 5 is used for preheating and a narrow molten region is produced around the periphery of bar 1, which is slowly drawn up to provide a recrystallised region as shown in Fig. 2.  Fig. 5 shows the change in donor and acceptor concentrations along a radius of the bar after recrystallisation and Fig. 6 the concentration after diffusion has taken place.  The larger diffusion coefficient of the aluminium results in aluminium predominating in the central region so that an NPN structure is produced.  Heating may alternatively be effected by electron bombardment.

Abstract: 335,789. Deutsche Gold-und Silberscheideanstalt vorm. Roessler. Nov. 9, 1928, [Convention date]. Addition to 308,226. Enamelling, vitreous.- The processes described in the parent Specification and in Specification 835,788 are applied to the decoration of metallic surfaces. In one example, an aluminium surface is scoured and coated with a lustre colour such as Craquelier purple lustre." The dried coating then is covered with a layer of glycerine 14 parts, gum arabic 12 parts, sugar 5 parts, spirit 20 parts, and water 49 parts, and the article afterwards fired. In a further example brass is coated with a ceramic enamel known as " Ring's blue " ground in 50 per cent of heavy oil. A covering layer as above is applied also in this instance. The character of the veined decoration produced can be modified by the preliminary treatment of the metal surfaces, for example polishing or etching or pre-heating in a suitable atmosphere. In some instances, especially for metals of low melting point, the ground layer of colour may be mixed with combustible material which burns during the firing. Nitro-cellulose is mentioned as an example.

Abstract: 968, 826. Liquid level detectors; pressure responsive devices. FMC CORPORATION. Aug. 26, 1963 [Sept. 7, 1962], No. 33762/63. Headings G1H and G1L. A liquid level differential sensing device comprises two open-ended conduits 11, 12 inserted in different portions of a body of liquid, means associated with each conduit for supplying pressurised gas to the conduit to force bubbles of gas out of the immersed end of the conduit, and means 24 sensitive to the difference between the pressures in the conduits. The device is illustrated as being applied to a flowing stream of sewage or other liquid containing solids, the stream passing through a screen fitted with a comminuting device 13, preferably a rotary cutter which moves across the screen to clear collected solids. The comminuting device is arranged to be operated automatically when the solids collected by the screen cause the liquid level upstream from the screen to rise a predetermined height from the level downstream from the screen. The conduits 11,12 are arranged upstream and downstream respectively from the screen, and each conduit is supplied with air from a separate pump (only one, 23, shown in Fig. 2) the output of which is adjustable. Flexible conduit sections 20, 21 lead to the conduits 11, 12 from the pumps through tee-fittings 41, 44 which also lead to the pressure sensing means 24. This means, Fig. 3, comprises two chambers 30, 31 divided by a flexible diaphragm. A normally open micro-switch 36 is fitted inside the chamber 30 and this has an operating plunger 47 adapted to be actuated by a screw 33 carried by the diaphragm 29. The diaphragm also carries a U-shaped bracket 35 to actuate a reset button 48 on the switch 36. The conduit 11 is connected to the chamber 31 and the conduit 12 to the chamber 30 so that as the liquid level rises upstream from the screen the pressure to force air out of the conduit 11 rises and this rise moves the diaphragm 29 to close the switch 36 and start the comminuting device 13 when the liquid level differential reaches a certain value. As the comminuting device clears the screen the pressure differential in the chambers 30, 31 is reduced and the switch 36 is reset switching off the device 13.
