Title: Improvements in or relating to semi-conducting devices
IPC: H01L21/205
Filed: 1965-04-12
Abstract: 1,033,868. Metal base transistors. TELEGRAPH CONDENSER CO. Ltd. April 12, 1965 [April 13, 1964], No. 15354/65. Heading H1K. A semi-conductor device comprises a monocryatalline semiconductor wafer, an epitaxial layer of the above semi-conductor material on the wafer, a layer of metallic material overlying the epitaxial layer and a layer of monocrystalline semiconductor material overlying the metallic layer, the metallic layer being no thicker than the mean free path of charge carriers therein. In an embodiment, a carbon pedestal 2 is heated by an R.F. coil 3, the pedestal 2 supporting a monocrystalline Si wafer 10. Hydrogen is introduced at 5 and flows via filter 9 through vessel 4 containing SiCl 4  and on into chamber 1 where an epitaxial layer of Si is formed by reaction at 1250‹ C. A layer of MoSi 2  is then formed by passing H 2 +MoCl 5  (from vessel 11) into the chamber operating at a temperature of 750‹ C. Finally, a further monocrystalline epitaxial layer of Si having the same crystal orientation as the first layer is formed at 1250‹ C. Molybdenum may be replaced by W, V, Cr or Ti. The layer formed by the deposition of Mo should be 50 to 500 Š thick to meet the mean free path requirements. If contacts are made to the two epitaxially grown layers and the metallic layer, then a metal base transistor may be formed.

Title: Improvements in or relating to the bleaching of textile materials
IPC: D06L4/24
Filed: 1959-05-05
Abstract: Textile materials are bleached with aqueous solutions of alkali-metal chlorites or alkaline-earth metal chlorites while they are carried on a conveyer belt woven from threads of a polyalkene or a copolymer of two or more alkenes.  Specified polyalkene threads are obtainable from polymers of ethylene and propylene and copolymers thereof, which are preferably woven to produce conveyer belts with an open weave. Preferably, the textile material is immersed in the chlorite solution, the excess liquid is removed by squeezing and the impregnated material is then led to the conveyer belt and steam admitted to at least a part of the belt.  The chlorite solution may have a pH adjusted to 3-4 by the addition of hydrochloric, sulphuric, nitric, phosphoric or maleic acid or a neutral solution of chlorite may be used and an acid, e.g. formic acid, admitted with the steam during treatment on the conveyer belt.  Alternatively the chlorite solution may contain a substance which decomposes to give an acid under the influence of heat, e.g. diethyl tartrate, the acid subsequently being liberated during steaming.  The bleaching of a tow of polyacrylonitrile threads is described.  Specification 870,309 is referred to.

Title: Improvements in systems for signalling over electric distribution networks
IPC: H01H51/32
Filed: 1935-05-27
Abstract: 446,611. Signalling over power circuits. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ, 12, Place des Etats-Unis, Montrouge, France. May 27, 1935, No. 15441. Convention date, May 28, 1934. Drawings to Specification. [Class 40 (iv)] In systems for signalling over power circuits by means of superimposed musical frequencies, the tuned receiving relays are protected from disturbances on the network by series or shunt non-linear resistances which limit the effective voltage across the relays due to the disturbances to a value lower than the voltage of the superimposed frequencies without appreciably affecting the sensitivity of the relays. Series and shunt resistances may be used in combination. The actual voltage limit imposed by the non- linear resistances may be a little greater than the superimposed voltages provided for, but as the disturbances are generally not of the same frequency as the signalling frequency, the selectivity of the relays will reduce the effective voltage of disturbances to a value which will not affect the relays. The shunt resistance may comprise silver sulphide or phosphide, silicon carbide, carbon (carbon filament lamp), and the series resistance may comprise an iron-hydrogen barretter or a metal filament lamp. The Specification describes and illustrates a known arrangement employing a spark gap as a protective device.

Filed: 1922-06-06
Abstract: 181,355. Martini & H³neke Maschinenbau Akt.-Ges., (Assignees of Hurlbink, E.). June 3, 1921, [Convention date]. Volatile liquids, recovering.-In recovering the volatile solvent used in applying thin coatings of caoutchouc &c. to woven fabrics, a gas, free from oxygen, is circulated through a hood 2 covering the drying-table 1 and through a condenser 17 and is returned by a pump 19 through a heater 21 to the hood. Part of the gas is allowed to escape through pipes 33, 35 and is replaced through a pipe 31 by fresh gas from a holder 26, sn that the amount of air in the circulating current never becomes sufficient to cause danger of explosion. The pressure of the gas escaping through the pipe 33 regulates, through a dia. phragm 29 and valve 30, the admission of fresh gas. The gas enters the hood 2 through nozzles 24, 25 directed against the inlet and outlet slots 3, 4 so that the entry of air is diminished and entering air is immediately mixed with the gas. When the apparatus is to be started, a cock 23 in the pipe leading from the heater 21 is closed and cock 32 is turned to connect the fresh gas supply to the nozzles 24, 25, and the slots 3, 4 are closed by rollers 44, 45, the cocks and rollers being operated simultaneously through connected levers. Fresh gas is then passed from the holder 26 through the hood 2, condenser 17, and pump 19 and escapes to the atmosphere until the air is displaced. The gas which is allowed to escape may be freed from solvent by cooling and washing or absorption, for example, in charcoal.
