Title: Improvements in or relating to vapour arc lamps
IPC: H05B31/00
Filed: 1920-02-26
Abstract: 139,506. Siemens & Halske Akt.-Ges. July 26, 1918, [Convention date]. Arc lamps. - A flame arc is confined by a tube and is prevented from spreading over the outside of the tube by a protecting or cooling device. The current density within the tube should be at least one ampere per sq. mm. Such an arc has high efficiency and concentration, and is suitable for projectors. It may be further compressed by a parallel magnetic field, or by increasing the pressure above atmospheric. An insulated negative electrode a within the tube f may co-operate with an external electrode b; or the tube may serve as one electrode, the other being either internal or external. The conductivity of the tube should be kept low, either by making it with thin walls or by using material of low conductivity, so that the are may not be formed at its end. Vapour such as mercury may be passed into the tube continuously or at intervals; or a vaporizable material such as an alkaline-earth or rare-earth compound in liquid, powdered, or coherent form may be fed in. If the tube burns away, the vaporizable material may form a lining, or may consist of a spiral metal wire within the tube. Introduction of carbon or like vapour into the arc is avoided. A current-conductor of carbon or tungsten is provided. Adjacent its end the tube is closely surrounded by the protecting device, consisting of an insulated sleeve or waterjacket k. The space between the tube and sleeve may be cleaned, for instance, by a mechanical device or by a current of gas, produced for instance by air suction. The part of the arc outside the tube may be compressed by a co-axial solenoid. According to the Specification as open to inspection under Sect. 91 (3) (a), the tube, when it is to form an electrode, may be lined with tungsten or other conductive material, or may be made from a mixture containing such material. This subject-matter does. not appear in the Specification as accepted.

Title: Improvements in or relating to semi-conductor devices
IPC: H01L21/56
Filed: 1959-02-20
Abstract: 909,921. Semi-conductor devices; glassmetal seals. SIEMENS-SCHUCKERTWERKE A.G. Feb. 20, 1959 [Feb. 21, 1958], No. 5974/59. Classes 36 and 37. A semi-conductor device is enclosed, apart from its external electrical connecting members, in an envelope made by embedding the device in a mass of glass particles and sintering to bond them together. A silicon PN junction diode is made by mounting the component parts of the diode on a molybdenum rod 3 in the lower half of a graphite mould 1. The component parts consist of an aluminium foil 4, silicon wafer 5, antimony-doped gold foil 6, tungsten block 7, and a connecting member 8 of molybdenum. To effect good sealing of conductors 3, 8 in the sintered glass the conductors are glazed at 15, 16 over a pre-oxidized surface which facilitates adhesion of the glaze. A ceramic sleeve 7 is placed on the wafer surrounding the conductor 8 and the mould then filled with glass granules and closed by graphite member 2. The assembly is heated by high-frequency induction in vacuum or a protective gas atmosphere to alloy the components of the diode together and sinter the glass into a unitary envelope. The thermal expansion coefficient of the external electrical connecting members should match that of the sintered glass. For instance, where, as in the above device the members are of molybdenum or of " KOVAR " (Trade Mark) borosilicate glass is used. If, on the other hand the members are of chromium-iron alloys or copperclad iron-nickel alloys alkali silicate or lead glasses are suitable. One of the members may be made rigid and be formed with an internal or external thread to facilitate mounting to facilitate mounting on a chassis. It may also form a support for cooling fins. In an alternative arrangement shown in Fig. 3, the ceramic cylinder is replaced by a hollow conical member 10a, which co-operates with conductor 13 to prevent the glass granules from coming into contact with the operative parts of the diode during the sintering process.

Title: Treatment and fractionation of hydrate-forming gases
IPC: C07C7/152
Filed: 1942-05-06
Abstract: Natural or other hydrate-forming hydrocarbon gases are separated into their constituents, including fixed or normally uncondensable gases, by maintaining the hydrates of certain of said constituents in different fractionating zones and separating from the hydrates in said zones different constituents of the gas existing in non-hydrated form.  A stream of carrier liquid containing the hydrates may be passed successively through the zones, the stream being depleted of hydrates by their selective dissociation in each zone.  Thus, a natural gas containing methane, ethane, propane and butanes is passed into a tower down which water and a non-aqueous carrier such as kerosene are caused to pass, the mixture being preferably emulsified, the temperature being maintained at 35 DEG  F., and the pressure 350 lbs. per sq. in. absolute, so that ethane and higher hydrates are formed, but not methane hydrate.  The carrier liquid containing the hydrates is passed to a hydrate fractionator, where the ethane hydrate is dissociated to ethane which is separated.  Specification 568,292 is referred to.
