Title: Improvements in knit fabric and method of making same
IPC: D04B9/54
Filed: 1944-11-24
Abstract: 632,145. Knitted fabrics. SCOTT & WILLIAMS, Inc. Nov. 24, 1944, No. 23426. Convention date, Nov. 27, 1943. [Class 74 (ii)] Uniting loops 21, 21<SP>1</SP> interknitted with a transfer course X to form a turned welt for a stocking are formed in the first few courses at recurring wales 3 with two wales 1, 2 between successive wales 3. As described, the welt fabric comprises a group of three wales 1, 2, 3 recurring successively. Needle loops are formed in every course of the first wale 1 and in every course except the first of the second wale 2, each loop being interknitted with the following loop. A loop is not formed in the first course of the third wale 3, and the loop 22 formed in the second course is held in an inoperative position by the needle until the seventh course is knitted, when it is interknitted with a corresponding loop 702 in that course. During the knitting of the third and fourth courses, the yarn is held by transfer bits at wale 3 to form uniting loops 21, 21<SP>1</SP>, which are reintroduced to the fabric at a transfer course X on the completion of the welt so that the loops are interknitted with a corresponding loop 215 in the transfer course to form a turned welt. The fifth and sixth courses are allowed to float across the third wale 3 whilst the corresponding needle is held in an inoperative position. The seventh course is knitted at the third wale 3 and is interlooped with the delayed knitted loop 22 of the second course which is reintroduced to the fabric by the operation of the withheld needle. The following courses are knitted in the normal manner until the welt is completed, when at the transfer course the transfer bits allow the uniting loops to be interknitted with the corresponding loops 215 in that course. The construction of the welt so formed causes the fourth course uniting loop 211 to bulge laterally beyond the other uniting loop 21. Alternatively a single uniting loop may be formed. The uniting loops and delayed knitted loop may be formed in any course and interknitted with any appropriate following course. The group of recurring wales may be larger than three and the initial course may be formed with loops at alternate wales. As described, the fabric is knitted upon the machine described in Specification 614,308. Alternatively it may be knitted by hand.

Title: Improvements in the construction of floors for buildings
IPC: E04B5/26
Filed: 1945-09-11
Abstract: 610,826. Floors and ceilings; casting in situ. WILSON, A. D. G. Sept. 11, 1945, No. 23440. [Classes 20(ii) and 20(iv)] In the construction of floors, clips 5, made of flat metal, are hung over ribs or beams 1 and support permanent or temporary shuttering, or the corners of permanent infilling such as hollow clay tiles 8 whose open ends abut against the sides of the ribs 1. The clips may be formed with upturned parts 10, Fig. 2, to locate the tiles. Clips for use when the rib 1 is against a wall, or to hang on the wall itself, have only one depending leg 5. The outwardly directed ends 6 may be left plain and may be drilled to secure the shuttering, or the parts 6, Fig. 7, may be bent out from an intermediate zone of each leg 5, the lower part 12 being hooked at 13 to support a ceiling. In Fig. 8, nuts 18 are locked against rotation by upturned parts 6x, or the nuts may be welded to the parts 6. The shuttering 14 is retained by a beam 15, bolts 16 and plates 17 which are finally removed. In a modification, single-legged clips, with associated nuts 18, support the shuttering directly by bolts passing through the shuttering and the clips, the heads of the bolts bearing on the shuttering, or angle irons spaced to permit the passage of the bolts. The shuttering may be spaced from the bottom of the ribs, to permit in situ concrete to pass to the undersides of the ribs.

Abstract: 1478597 Control of D.C. motors CONSIGLIO NAZIONALE DELLE RICERCHE 29 May 1974 [30 May 1973] 23756/74 Heading H2J [Also in Division G3] In a control system for two peristaltic pumps each driven by a D.C. motor M1, M2, the mixture of liquids supplied by the pumps is controlled according to a predetermined ratio or to the relative ratios between the liquids and their concentrations in a solution (see Divisions G2- G3), by controlling the motor speeds so that when the speed of one pump is increased or decreased according to a predetermined function, as set by adjustment of a potentiometer P1, the speed of the other pump is decreased or increased respectively in accordance with the same predetermined function. Such control is effected by varying the speeds of motors M1, M2 through transistor amplifiers TD1, TD2 respectively controlled by the outputs of a differential amplifier TR1, TR2, TR3, having one input connected to potentiometer P1 and the other to earth via resistor R1. Adjustment of potentiometer P 1 may be stepwise or continuous and the latter linear or non-linear, to provide variations about an equal-motor-speed condition set by adjustment of resistor P2, a further potentiometer P3 controlling a constant current transitor TR10 to adjust the operating point of the differential amplifier.

Abstract: 226,468. Automatic Telephone Manufacturing Co., Ltd., Mercer, R., and Tench, F. Sept. 18, 1923. Drawings to Specification. Automatic exchange systems.-In systems using large-capacity step-by-step selectors wiperselection is effected by applying a certain potential to one of the speaking leads and takes place in the interval between the seizure of the switch and the energization of the release relay. In the connector described, the line relay in the absence of this discriminating potential energizes in series with a wiper-choosing relay which locks up, its original circuit being disconnected by the redease relay. The discriminating potential short-circuits the wiper-choosing relay. Detailed description is given of group selectors forming the subjectmatter of Specification 226,467 which are not effectively operated in response to the first digit but according to its value connect a wiper-selecting potential to one of the speaking leads. Detailed description identical with a part of Specification 227,888 is given also of a system in which a two-wiper simultaneous-hunting group selector similar to that described in Specification 170,385 gives access to the same trunks over its 1st and 6th, 2nd and 7th, &c. levels. If the first digit has the higher value, post springs are operated to cause one of the talking wires to be grounded in the interval between the energization of the switching relay and the relapse of the release relay. The second selector is also of the largecapacity simultaneous hunting type and. is arranged to repeat the discriminating potential to the connector bv means of a relay which energizes in series with the line relav unless it is shortcircuited by the discriminating potential at the first selector. Repeaters may be provided with a similar relay for repeating the discriminating potential.
Patent GB-933296-A (GB)
Title: Improvements in or relating to the manufacture of devices containing thin layers
IPC: H01B3/00
Filed: 1961-07-05
Abstract: 933,296. Magnetic and super-conductive stores, made electrolytically. SIEMENS & HALSKE A.G. July 5, 1961 [July 5, 1960], No. 24301/61. Class 41. [Also in Group XXXIX] A magnetic or superconductive store device is made by electro-plating a thin layer of a material on a base which is of low resistance under the conditions of plating and high resistance when in use as a store. For example, a metal whose electrical conductivity increases with increasing temperature is plated at normal temperature and the device used at a lower temperature. The process can also be supplied to materials which are photo-conductive. Examples of the base layer include cadmium or lead sulphide, cadmium telluride, and selenium used as photo-conductive materials and used as a base layer, and lead or tin as superconductivity materials sandwiched between layers of germanium. The preferred process consists in immersing a glass support coated with CdS by vapour deposition, in CuSo 4  solution in which is mounted a copper anode. A beam of light passes through the transparent side of the container and through a disc having slits, by which copper is deposited on the CdS layer as strips corresponding to the pattern of slit openings. Further layers or strips of CdS, magnetic alloys, tin or other metals are then applied to build up the device. In Fig. 2 a section of such a magnetic store device shows a carrier support of glass 1, layers of photo-conductive material 4, with intervening strips of copper 2b, orthogonal strips of copper 2a, and situated at these " cross-over " points are magnetic materials 3 of circular shape. An insulating layer 5 is then applied. Both the copper and nickel-iron alloy used as magnetic material are deposited electrolytically under focused light rays; a magnetic field is applied during deposition of the ironnickel. A plate of silicon may be used instead of glass. Fig. 5 shows a section of a superconductive store, consisting of a glass support 1, layers of germanium 4a, strips of lead 3, 3a which becomes super conductive at low temperature, narrow parallel strips of tin 2c, 2d, 2f, under the central bridge 3a, and serving as writing and reading wires. The tin and lead are deposited electrolytically at room temperature, and the device assembled with a protecting insulating layer 5 is operated at 3.5 K, when regions 3 become super-conductive, while germanium has low electrical conductivity. In a further modification, a germanium plate is plated with lead at room temperature, the surface of the lead is sulphided, and a second lead plating is applied under light. This layer is also sulphided and tin conductors plated on, which serve as active memory members, the lead layer acting as control line.
