Title: Electric arc furnace
Inventor: WYNNE PETER JOSEPH
IPC: H05B7/109
Filed: 1965-01-19
Abstract: 1,031,255. Automatic control systems for arc furnaces. McGRAW-EDISON CO. Jan. 19, 1965,No.2303/65. Heading G3R. In a polyphase arc furnace, the feeding mechanism for each consumable electrode 40 comprises a differential assembly 59 having an output, constituted by a plate 62 connected to the electrode, a first input constituted by a screw shaft 66 and a second input constituted by a nut 65 on the shaft 66. The separate shafts 66 are all driven by one A.C motor 81 running at constant speed; the nuts 65 are separately driven by individual D.C. motors 85 each responsive to the arc conditions of its relative electrode and under normal.operating conditions the arrangement is such that there is no relative movement between nut and shaft and therefore no output from the differential assembly. If any arc gets too short or too long, the speed of the motor 85 associated with the particular electrode will alter accordingly and the nut will move relative to the shaft whereby the electrode is moved until the arc is the correct length. The motor 85 is supplied from a Ward Leonard generator having a control winding energized in dependence upon electrode current (Fig. 7, not shown).

Abstract: 705,901. Automatic gain control. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Jan. 12, 1951 [Jan. 31, 1950], No. 2449/50. Class 40 (5). [Also in Group XXXV] In modulated carrier wave apparatus the smoothing of an automatic control voltage is effected by applying the voltage to the input of an amplifier through a resistance and connecting the smoothing capacitor between the input and a point at which appears a voltage in amplified form and of opposite polarity. By this means a smaller smoothing capacitor may be used. In the circuit shown a control voltage for automatic gain or frequency control is applied through a smoothing resistor 11 to the grid of the first valve of a cathode coupled pair and the smoothing capacitor 6 is connected between this grid and the first anode or the junction of output resistors 8 and 9 or the output of a further amplifier 14 connected to the junction. If a control voltage of the opposite sign is required it may be derived from the anode of valve 2. Specifications 589,613, [Group XXXV], and 626,088 are referred to.

Abstract: 305,043. I. G. Farbenindustrie Akt.- Ges. Jan. 28, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Vinyl ester resins are freed from unpolymerized ester by heating to about 80‹-100‹ C. in water or water vapour, whereby the volatile material in the resin is replaced by water. The water is then removed by treating the resin in a vacuum at about 100‹ C. or by cooling, comminuting, and submitting to a vacuum. In an example, the resinous polymerization product from vinyl acetate is placed in a kneading- machine provided with a distilling-device, and heated to 80‹ C. while stirring, water vapour being blown in. After about an hour, the mass is kneaded at 80‹-100‹ C. under reduced pressure to remove the moisture. After cooling, a colourless product is obtained which may be freed from bubbles by again heating to 80‹-100‹ C. If a higher temperature is applied, the viscosity and elasticity of the resin are diminished.

In Fig. 1, a locking ring 10 of slightly elliptical form is housed in an annular groove 7 in a shoulder 6 of a bolt head 1, and contacts the smooth cylindrical wall of a recess 9 in an article 5. A ring shaped to have three or more areas in contact with the wall may alternatively be used. In Fig. 3a, the locking ring 10 is housed in a longitudinal extension of a nut 15 and engages an unthreaded surface 17 at the end of the shaft. In Fig. 4a, not shown, the surface 17 is on the side of the shaft threaded portion away from the shaft end. The ring 10 may alternatively be housed in a groove in the shaft and contact a smooth inner cylindrical wall of the nut extension (Figs. 3b and 4b, not shown). In a pipe coupling, Fig. 5, the ring 10 is housed in a groove in the wall of one pipe 25 and contacts an internal cylindrical surface of an axial extension 23 of a nut 20. A lip 22 of the nut clamps the end flange 27 of a second pipe 28. Again, the ring may be housed in a groove in the nut extension (Fig. 6, not shown). In Fig. 7, the locking ring 30 is a sleeve engaging outer cylindrical surfaces of the nut 35 and the pipe end, the points of contact with the nut being circumferentially offset from those with the pipe. The sleeve may be secured or clamped to the nut or to the pipe or bolt. A modified sleeve (Fig. 9, not shown), is clamped to a pipe end and has axially extending fingers which frictionally engage the outer surface of the nut.

Title: Copolymerization with monomer complexes
IPC: C08F20/62
Filed: 1962-01-26
Abstract: A first monomer, which is a polar vinyl or vinylidene monomer containing negative groups that do not promote electron pair release at the double bond and which is responsive to free radical initiation, is copolymerized in the presence of a free radical initiator and a Friedel-Crafts catalyst with a second monomer which is an olefine or substituted olefine containing one or more groups promoting the release of electrons at the double bond and responsive to Friedel-Crafts catalysts.  The first monomer may be vinyl or vinylidene halide, acrylonitrile, methylacrylate, methacrylonitrile; acrylic or methacrylic esters or acids; acrolein or vinyl acetate. The second monomer may be 2-methyl-1-pentene, ethylene, propylene, isobutylene, 2-methyl-styrene, isopropenyl toluene, vinyl ethers, hexene-1 or methallyl chloride.  An organic solvent, e.g. ethyl ether, ethyl acetate, acetone, dimethylformamide, butyrolactone, dimethyl-sulphoxide, or methylene or methyl chloride may be present. The first monomer and Friedel-Crafts catalyst e.g. ZnCl2, AlCl3, FeCl3, CdCl2, BF3 may be used in equimolecular amounts at -78 to +175 DEG C.  The Friedel-Crafts catalyst may first be complexed with the first monomer and then co-polymerized with the second monomer in the presence of the initiator, which may be contained in the second monomer, or the catalyst may be added to the mixture of monomers and initiator.  The initiator, e.g. 0.001-5%, may be benzoyl peroxide, cumene hydroperoxide, peroxidised butyl ether, azobisisobutyronitrile, g  radiation, boron or aluminium alkyls. Modifying agents, e.g. formaldehyde, acetone or acetic acid may be incorporated in the copolymers which may be formed into fibres or films.
