Patent GB-1501506-A (GB)
Title: Electromagnetically actuable valve units
IPC: B60T15/02
Filed: 1975-01-24
Abstract: 1501506 Valves ROBERT BOSCH GmbH 24 Jan 1975 [26 Jan 1974] 3094/75 Heading F2V An electromagnetically operated valve has two closure members 27, 28 biased away from each other by a spring 29 and mounted in an armature 13 biased to the position shown by a spring 14, the force of attraction between the electromagnet and the armature being approximately matched to the combined effect of the springs 14, 29 throughout the stroke of the armature. A third spring 37 is provided between the armature and a portion 9 of the housing. When the electromagnet is energized by a small current the armature moves downwardly until the closure member 28 is seated, an increase of current causing a further movement of the armature to open the closure member 27. The third spring is now fully compressed and a slight separation of the armature from the portion 9 is maintained by a spacer 16 to eliminate the rapid increase in the force of attraction between the electromagnet and armature during the last part of the movement. The valve may be used to connect a pump 3 to a receiver 2 or a discharge line 4.

Title: Electric conductor of solid cross-section and smooth surface
IPC: H01B5/10
Filed: 1928-01-31
Abstract: 303,666. Metallbank und Metallurgische Ges. Akt.-Ges., and Zagorski, J. Jan. 31, 1928. Cores for cables. - Relates to a conductor for use in overhead high-tension transmission lines, in which a core of stranded wires is surrounded by an annular conductive shell of metal strips which fit together and have a smooth outer surface. According to the invention, the strips a, Fig. 1, which surround the stranded core b, are formed with projections and recesses which interlock and prevent relative displacement of the strips. The projections and recesses may be of various shapes and they may be dispensed with, if, as shown in Fig. 7, the strips are made sufficiently deep. In this'case, the lateral meeting surfaces of the strips support one another when the conductor is bent. The wires of the core, and the strips, may be made of different metals.

Patent GB-640105-A (GB)
Title: Improvements in and relating to the manufacture and production of artificial threadsfrom viscose
IPC: D01F2/06
Filed: 1948-02-09
Abstract: Artificial threads are produced from viscose using coagulating baths or ancillary processing liquids containing sulphuric acid, one or more metallic salts, a mineral oil, for example a white oil, or a non-drying fatty oil, for example a vegetable oil such as olive oil, or a liquid wax, for example sperm oil, and an emulsifying agent for the oil comprising a polyglycol ether obtained by reacting from 2 to 12 mols. of ethylene oxide with one mol. of a fatty alcohol having not less than 10 carbon atoms in the chain.  The process may be continuous, the viscose being extruded into a coagulating bath and the thread thus formed subjected without any break to a series of treatments and to drying and winding on to a package.  The coagulating or processing liquid may contain a white oil and lauryl triglycol ether.  The processing liquid may contain 0.8-4 per cent by weight of sulphuric acid, 1-10 per cent sodium sulphate, 0.1-1.5 per cent zinc sulphate and 0.1-1 per cent oil.  The proportion of polyglycol ether may be 2-10 per cent by weight of the oil.  In an example, 5 grams of a mineral oil in which is dissolved 5 per cent of a lauryl polyglycol ether made by condensing 1 part of lauryl alcohol with 0.7 part of ethylene oxide, is added to each litre of a processing liquid for effecting further coagulation of viscose threads.  This liquid contains 2.0 per cent of sulphuric acid, 4.2 per cent of sodium sulphate and 0.5 per cent of zinc sulphate.  Other polyglycol ethers which may be used are obtained by reacting 1 part by weight of cetyl alcohol with 0.8-1.0 part of ethylene oxide, or 1 part of octadecyl alcohol with 1.0-1.2 parts of ethylene oxide.  The addition of the oil and emulsifier to the coagulating or processing liquid is said to prevent the formation of hard deposits on thread guides, godets, or thread-advancing reels.  Specifications 467,500 and 541,099 and U.S.A. Specification 2,394,519 are referred to.

Abstract: 1372835 Valves CESKOSLOVENSKA AKADEMIE VED 25 Jan 1973 [1 Feb 1972] 3935/73 Heading F2V [Also in Division A5] A non-return valve, e.g. an artificial heart valve, comprises at least two movable closure members 1 pivoting inside a ring 2 about axes represented by chords of the ring. The closure members are attached to the ring by thin elastic suspensions 3. Closure is effected by forces of adjacent closure members coming into contact, further movement being limited by contact between part 5 of the closure member and the inner wall of the ring. The closure members may have their contact areas increased by the provision of lips 7 which extend in a down-stream direction. The ring and closure member may be reinforced by polyester textile fibres. A stainless steel collar may be inserted in the peripheral part of the ring. The valve may be made by moulding a mixture consisting of 60 parts of hydroxyethyl methacrylate, 0À25 parts of ethylene dimethacrylate, 10 parts of ethanol, 15 parts of 1% aqueous solution of ammonium persulphate and 15 parts of 1% aqueous solution of sodium disulphite. This mixture produces a hydrophyllic gel which swells when soaked in a physiological saline. Alternatively, the valve may be made from a silicone rubber in which case reinforcement is unnecessary.

A semi-conductor device consists of a monocrystalline semi-conductor substrate with at least one diffused heavily doped zone in its surface and a layer which has been grown epitaxially over said zone. A typical arrangement illustrated in section in Fig. 5 is formed from a 100 ohm cm.

A three-way AND gate, Fig. 9, is formed from a high resistivity P-type wafer 95 on which highly doped P layers 99, 97 have been formed by diffusion. Low resistivity P layers 93, 91 are epitaxially deposited on layers 99, 97 and groups of three N-type layers 81 and one P+ layer formed by diffusion into layer 93. The wafer is then diced into elements including one of these groups and a N+ layer formed by diffusion into layer 91.
