Title: Improvements relating to gill boxes
Inventor: HILL MOORE
IPC: D01H5/04
Filed: 1956-05-17
Abstract: 857,542. Gill boxes. MACKIE & SONS Ltd., J. May 17, 1957 [May 17,1956], No. 15416/56. Class 120(1).  In a screw gill box having movable guides 6 for controlling the fallers 5 during their passage from feed screws 1 to return screws 11, an additional pusher mechanism acts on each faller to push it away from guides 6 along the beginning of its return path. The pusher mechanism comprises a member 21 working in association with each guide 6. Member 21 and guide 6 are pivoted at 22 and 20 respectively and are acted on by a common compression spring 24, Fig. 2. When a faller 5 reaches the end of a feed screw support slide 4 it is forced down by the ususal cam 7, Fig. 2, to the Fig. 3 position, causing guide 6 and member 21 to move back. As the descending faller clears slide 4, guide 6 and member 21 move back to the Fig. 2 position, the top end of member 21 overtaking the guide and engaging the faller just as or before it engages a return screw slide 10. The faller is thereby rocked into a more upright position so that any rebound will be towards the underside of slide 4 and damage to cam 7 will be avoided; also the faller is caused to engage the return screw 10 at two points 30, 31 so that the screw takes over control of the movement of the faller without jolting. In alternative arrangements, the pusher mechanism may be controlled by cams driven from the feed screws, or the pusher mechanism may consist of rotating cams working in synchronsim with the guides and acting directly on the fallers.

Patent GB-1101445-A (GB)
Title: Process for the production of synthetic resins
IPC: C08G63/87
Filed: 1965-04-13
Abstract: A soluble product which is convertible into the insoluble state by polyesterification is prepared by mixing or partly esterifying (I) an addition compound of 1 p.b.w. of maleic anhydride with 1.5-2.5 or, in the presence of amine (see below), 3.0 p.b.w. of an unsaturated oil fatty acid, or a hydroxy-free polyol ester thereof, containing only isolated double bonds or one pair of conjugated double bonds, with (II) a diol in amounts approx. equivalent to the carboxyl or anhydride groups of I.  Preferred oils have iodine values of 120-170 cg. I/g. From 3-7% by weight of the addition compound of a primary or secondary amine of low volatility may be used in place of part of the diol.  Suitable diols are diprimary glycols, e.g. ethylene or polyethylene glycols or butane-1,4-diol; less preferred are e.g. a propane-1,2-diol, butane-2,3-diol, dipropylene glycol, and fatty acid monoesters of triols, e.g. of glycerol and trimethylolpropane; dimethylol alkylphenols may also be used in minor amounts.  Suitable amines are e.g. ethylene diamine or polymers thereof, and amine diols, e.g. diethanolamine. The soluble product may be obtained by heating (I) and (II) together at about 100 DEG  C. until the mixture is clear.  It may then be dissolved in an organic solvent, or in an aqueous ammonia or amine solution.  Alternatively the adduct I may be dissolved in the aqueous solution before the diol is added. In examples adducts of maleic anhydride with soybean oil or linseed oil or linseed-soya-dehydrated castor oil or dehydrated castor-safflower oil are heated at c. 95 DEG  C. with ethylene glycol or diethylene or dipropylene glycol or polyethylene glycol or butane-1,4-diol with and without a 2:6-dimethylol-4-t-alkylphenol and the mixtures are dissolved in an aqueous solution of ammonia and diethanolamine or triethylene tetramine and optionally diethylene glycol monobutyl ether or ethoxyethyl acetate, to give aqueous stoving lacquers of particular use as primers.ALSO:Aqueous stoving lacquers comprise a mixture or partial esterification product of (I) an adduct of 1 p.b.w. maleic anhydride and 1.5-2.5 p.b.w. (up to 3.0 p.b.w. when an amine is present) of an unsaturated oil fatty acid, or hydroxyl-free polyol ester thereof, containing only isolated double bonds or one pair of conjugated double bonds, and (II) a diol, in approximately equivalent amounts; from 3-7 wt. % of the adduct of a primary or secondary amine may replace part of the diol. (see Division C3). In Examples such products (I) are mixed with diols (II) and diethanolamine or triethylene tetramine in aqueous ammonia solution optionally also containing diethylene glycol monobutyl ether or ethoxyethyl acetate and a pigment.  The lacquers are used to coat steel panels; they may be applied by dipping or spraying.

Abstract: 1,185,667. Semi-conductor devices. MORDOVSKY NAUCHNO-ISSLEDOVATELSKY ELEKTROTEKHNICHESKY INSTITUT. 6 April, 1967, No. 15886/67. Heading H1K. In an electrically symmetrical thyristor, i.e. one having a thyristor-like switching characteristic for both directions of current flow through the device; the two shunted emitter regions 7, 8 are positioned so that when one face of the device is projected orthogonally on to the other, regions of the two faces which coincide are of opposite conductivity type, except in the region of the control electrode 17. This electrode 17 is situated on a region 14 which is surrounded on the device surface by material of the opposite conductivity type, and which is positioned on the line of emergence of the major part of the emitter junction 9. The device illustrated is formed by diffusion into a basically N-type Si crystal having a resistivity of 40 #cm. and a diffusion length of 0À3 mm. The junctions 5, 6 and 9, 10 are respectively diffused to depths of 7-80 Á and 10-15 Á. The Ni control electrode is deposited on an area 14 which is entirely of one conductivity type. In this embodiment the control voltage applied between the control electrode 17 and the current electrode 15 is limited to one polarity. In a second embodiment, Figs. 6-10 (not shown), the control electrode (17) is in contact with four equal-area quadrants (25-28) of alternating conductivity type, situated on the line of emergence of the upper emitter junction on the upper surface. Each of the quadrants (25-28) is surrounded on the surface by material of the opposite conductivity type, sectors (30) and (33) being provided in the regions (22, 23) adjacent quadrants (25) and (28) respectively to make this possible. In this case the device can be switched by a control voltage of either polarity between the control electrode (17) and the adjacent current electrode (15). A third form of the invention, Figs. 4, 5 (not shown), is similar to the form of Figs. 6-10, but the control electrode is situated on a pair of complementary semi-circular areas (42, 43) of opposite conductivity type, the line joining these two areas coinciding with part of the line of emergence of the upper emitter junction on the upper device surface. The line of emergence of the lower emitter junction on the lower device surface is adjusted so that half of the orthogonal projection of each of the areas (42, 43) on to the lower surface coincides with a region of the same conductivity type as the relevant area (42 or 43), and half of the projection coincides with a region of the opposite conductivity type.
