IPC: B01D17/04
Filed: 1950-01-09
Abstract: 678,025. Gravity-separation apparatus; filters. BENDIX AVIATION CORPORATION. Jan. 9, 1950, No. 536/50. Class 46 Liquid contaminant, e.g. water, and solid contaminant are removed from a fluid, e.g.. petrol or kerosene, by firstly removing a substantial proportion of the solid matter as by filtering, then causing the minute droplets of the contaminating liguid to coalesce to form relatively large droplets which separate from the fluid under treatment and then filtering the fluid through a third element to remove the contaminant and the remaining particles of solid matter. As shown, the contaminated fluid, e.g. petrol containing water, passes from inlet 14 in series through a filtering element 30 constituted by a pleated paper filter element for removing solid matter from the liquid, then through a mass of fibrous. material 32 such as glass fibre, for coalescing the droplets of the contaminating liquid or dispersed phase which separate out and settle in the bottom of the tank 12. The fluid is passed to a second filter, such as an edge filter 18, spaced from the mass 30, for removing the small droplets of contaminating liquid carried over and the remainder of the solid matter, to outlet 20. The pleated paper filter element 30 is rather porous and impregnated with some material such as resin to make it resistant to water, gasoline, kerosene and the like, and forms the outer bounding wall of the glass fibre 32, the inner wall being constituted by a perforated metal or wire screen cylinder 34. The two ends of this so-formed unit are sealed by impervious rings 36, 38 cemented to the ends of the pleated paper and to cylinder 34. The first filter, namely filter 30, may if desired be separate from the fibre mass 32, e.g. an edge-type filter element may be substituted therefor. Any free water which may be removed before it passes through the element 30 collects in the lower end of chamber 24 and is drawn off through passage 66. After passing through the fibre mass 32 into the central portion 26, the mixture passes to the edge filters 18, and the water settled to the bottom of the tank 12 is drained off through outlet 22 controlled by a valve 60 and float mechanism 62 which will float on the contaminant water but not on the other liquid, kerosene, gasolene or the like. In an alternative embodiment the edge filters 18 are located above the fibre mass 32. Specification 672,737 is referred to.

Abstract: 555,291. Control systems for resistance welding; transformer arrangements. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Jan. 15, 1942, No. 599. Convention date, Jan. 16, 1941. [Class 38 (iv)] Thermionic control.-A reactor or transformer 19, for example in a resistance welder circuit, is energized through space discharge devices such as ignitrons 11, 13, 15, connected to a polyphase source so as to supply a periodically pulsating potential such that the current in the primary winding builds up to a maximum at which a relay 21 is operated to disconnect the exciting circuits of the ignitrons. The ignitron which is conducting at this instant is extinguished when the algebraic sense of reactor voltage, source voltage, and the voltage of a bias battery 39 becomes sufficient to ignite a control valve 37, whereby an ignitron 35 is fired and a suitably polarized precharged condenser 31 is connected across the conducting ignitron to extinguish it. The welding current resulting from the ensuing collapse of flux in the reactor is controlled by a parallel circuit comprising a space discharge device, such as an ignitron 41, and an adjustable resistance 43 which circuit is completed by the ignitron of a control valve 136 when a certain reactor voltage is reached. The system is controlled by a manual switch 45 and auxiliary relays 23, 81, closure of a contact 47 causing actuation of fluid pressure means applying the electrode 57 to the work and the closure of a switch 71 to energize the ignitrons when the correct electrode pressure is reached.

Filed: 1939-01-10
Abstract: 522,856. Belt fastenings. MASTABAR BELT FASTENER CO., Ltd., TEBB, B., and HARTLEY, W. W. Jan. 10, 1939, No. 834. [Class 80 (i)] With the usual type of V-shaped wire fastener, the limbs 10, Fig. 1, are joined by a curved loop portion 16 with the result that when the limbs are clinched into the belt, the projecting portion of the loop assumes a semi-elliptical form with the curvature at the extreme end so acute that the pin used to connect the loops is subject to jamming, torsion and ultimate breakdown. According to the invention, the part 22, Fig. 3, is made straight or substantially straight and merges into the limbs by curved side portions 24. With such a construction, the projecting loop portions 16, Fig. 5, have a uniform curvature, being substantially semicircular arcs on a base equal to the thickness of the belt. The connecting pin 20 will therefore touch the loops at only one point and a rolling action instead of rubbing will occur. If the wire be somewhat thin, the part 22 may be given a slight curvature.

Title: Improvements in and relating to semiconductor devices
IPC: H01L27/00
Filed: 1970-01-08
Abstract: 1291383 Semi-conductor devices PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 8 Jan 1970 [11 Feb 1969] 981/70 Heading H1K A semi-conductor device comprises a substrate of one conductivity type, an epitaxial layer of the opposite conductivity type, a lateral transistor formed within an isolated island of the epitaxial layer, the island having a buried layer, of the opposite conductivity type at its junction with the substrate, the emitter, but not the collector, of the transistor reaching down to the buried layer. The P type silicon substrate 2 has an N type region formed in its surface prior to deposition of the N type epitaxial layer 4, the region being subsequently diffused into the layer 4 to form the buried layer 18. P type material is diffused into the surface of the layer 4 to form the separation zones 14 and hence isolate the island 5, and also to form port 15 of the emitter of the transistor, which port contacts the buried layer 18. A second diffusion takes place to form port 16 of the emitter, and also the collector zone 17. Formation of the emitter port 16 and collector 17 simultaneously is stated to enable higher precision to be achieved. An N<SP>+</SP> contact zone, to the base of the transistor is also formed, and aluminium electrodes 26 to 31. The contacting of the buried layer 18 by the emitter is said to decrease vertical injection of charge carriers, the non-contacting by the collector maintaining the base-collector breakdown voltage level. In another embodiment, additional P type regions are provided in the substrate surface besides the N type region which subsequently forms the buried layer 18, these regions subsequently forming ports (40), Fig. 6 (not shown) of the separation zones 14, and port 15 of the emitter. Further simultaneous diffusion of ports (41) of the zones 14, collector 17 and emitter port 16 takes place, ports 15 and 16 of the emitter becoming contacted. Substrate material may alternatively be of germanium or an A 3 B 5  compound. Dopants include antimony, arsenic, boron and phosphorus. A vertical transistor 23, 22, 6 may be formed simultaneously in another island 6.
