Abstract: 719,297. Envelopes. GULSON ENGINEERING CO., Ltd., CROMPTON, J. B.. HAYWARD, H., and HUTCHINSON, A. D. May 21, 1952 [Feb. 21, 1951], No. 4175/51. Class 146(2) To enable a strip assembly of interconnected envelopes to be fed through an addressing or other printing machine, the normally lower edge of each envelope has a portion 10 thereof extending over and free from that end part of the flap 3 of the next envelope connected thereto so that a lip 11 is formed which can be engaged by feeding means in the printing machine. As shown, the assembly comprises separate blanks of paper or plastic material each having a back 2, a flap 3, and a front 4 provided with side wings 5 and transverse wing 6, and they are joined together in strip form such that the back 2 forms the back of the preceding envelope when it is secured by adhesive to the wings 5, 6 of that envelope. The assembly of the blanks, coating of the side edges of the backs 2 and flaps 3 at 9 with adhesive, folding of the wings 5, 6, and creasing and perforating the flaps 3 at 7 and 8, respectively, can be carried out in the machine described in Specification 719,298, [Group XVII]. In affixing each back 2 to a front 4, the back is so positioned that a narrow margin 10 of the wing 6 is left free from the back 2 which is adhesively affixed to the remaining portion of the wing 6. This free portion 10 extends over the upper edge of the flap 3 of the next envelope, and provides a lip 11 which can be engaged by a claw of a feeding means in a typewriter or an addressing or franking machine. The wings 5, 6 could be formed on the back portions 2, instead of, or in addition to, those on the front portions 4. In a modification, the envelope assembly is formed from a continuous strip which provides an alternating series of flaps and fronts, and the backs are provided by affixing thereto, by adhesive, blanks which each comprise the back, side wings, and lower transverse wing. Each such blank is affixed so that a narrow portion of the lower transverse folded wing is left free from the front, and a transverse lip is provided.

Title: Improvements relating to multi-speed dynamo-electric machines
IPC: H02K17/14
Filed: 1919-02-20
Abstract: 143,600. Creedy, F. Feb. 20, 1919. Alternating-current induction machines.-A multispeed polyphase induction motor has primary windings on both stator and rotor capable of direct excitation from a polyphase supply and of producing fields of different pole-numbers; each winding is also adapted to serve as a secondary for one or more primary pole-numbers when the other is excited from the line. The cross-connexions for the secondary currents induced in these windings are such that approximately bal. anced polyphase currents flow therein. Suitable methods of changing the pole-numbers of primary windings are described in Specifications 18887/14 and 123,395. The number of sections (or bands of current of a particular phase; of the secondary winding should not be much below three times the number of pole-pairs of the inducing. field; the necessary increase in the number of sections may be obtained by connecting together points in the winding which an equipotential when the winding is acting as a primary. Figs. 1 and 2 are simplified diagrams of a three-phase four-pole primary winding of twelve sections 1, 1<a> - - 12, 12a Fig. 1 showing the relative dispositions of the sections on the periphery of the machine. and Fig. 2 their star-parallel connexion. The winding is adapted to act as a secondary on two, six, or eight poles; as shown in Fig. 2, half the sections are relatively reversed. Figs. 3 and 4 show a winding of six sections connected to art as a two-pole primary and as a four-pole secondary; Fig. 5 shows a winding of twelve sections connected to act as a fourpole primary and as a two-pole secondary. A two-speed motor may thus be constructed by placing the winding shown in Fig. 4 on the rotor, and the winding shown in Fig. 5 on the stator. Fig. 6 shows a mesh-connected rotor winding of twelve sections, the angles of the mesh and the midpoints of its sides being joined to slip-rings M1, M2, M3, S1, S2 S,. A switch S enables the sliprings M1, M2, M3 to be joined to three-phase mains L1, L2, L3, when the winding gives eight poles, or the slip-rings S1, S2, S3 to be connected to the mains and the other slip-rings short-circuited when the winding gives four poles; the internal parallel connexions enable the winding to act as a secondary for six poles. Examples of motors capable of producing three, four, five, six, and seven different speeds are given in the Specification. Rules and tables are also given showing the numbers of sections which may be connected in parallel with and without relative reversal for particular combinations of pole-numbers. External connexions may be brought out from tappings on the windings for resistance control.

Title: Electrolytic diaphragms and method of electrolysis using the same
IPC: C25B13/00
Filed: 1975-02-03
Abstract: 1493164 Treatment of ion exchange membranes; ethyleneimine polymer TOKUYAMA SODA KK 3 Feb 1975 4589/75 Headings C3P and C3R [Also in Divisions B2 C7 and B5] A polymeric cationic exchange membrane for use as an electrolytic diaphragm and containing both cation exchange groups and fluorine atoms in a main layer also comprises a thinner, secondary layer which is electrically neutral (i.e. contains no ion exchange groups or equal equivalent amounts of both cation and anion exchange groups) and/or which contains anion exchange groups. The secondary layer is generally formed by a surface treatment and will be on the outside of the main layer but by a subsequent lamination of two membranes an internal layer can be formed. A particularly preferred treatment consists of converting sulphonic acid cation exchange groups to sulphonyl halide, treating the surface groups with an amino compound, then regenerating the internal sulphonic acid groups. Other treatments exemplified include coating with a compound or polymer optionally with a subsequent irradiation to graft the layer to the membrane, reacting surface cation exchange groups to convert them to non-ionic groups, or decomposing them, e.g. by oxidation, or neutralizing them with an anion exchange material or by polymerizing a monomer or effecting a chemical reaction on the surface with or without grafting to the surface. The layer formed may be non-ionic or may contain anionic groups or may have anionic groups subsequently introduced. The membranes are used as diaphragms in electrolytic cells particularly for the production of chlorine from alkali metal chlorides. The chemical after-treatment of polymers is also exemplified as follows: (5) poly-α,#,#<SP>1</SP>-trifluorostyrene is chlorosulphonated and simultaneously cross-linked by reaction with chlorosulphonic acid. The product is arylated on the surface by a Friedel-Crafts reaction with naphthalene, xylene, fluorene or benzene; (6) and (24) poly-α-fluoro-styrene is reacted with phosphorus trichloride and oxidized to introduce phosphoric acid groups; (9) polyvinylidene fluoride is fluorosulphonated with fluorosulphonic acid; (10) PTFE grafted on the surface with polystyrene is reacted with benzoyl chloride and aluminium chloride to introduce benzoyl groups into the styrene units; (22) poly-α-fluoro-styrene is chloromethylated and aminated; (29) polychloromethylstyrene is dispersed in dimethylsulphide and dialysed to obtain a polymer containing sulphonium salt groups. Ethylene imine is matrix polymerized in the surface layer portion of one side of a commercial perfluoro-type cation exchange resin containing sulphonic groups in Example (14).
