Title: Improvements in or relating to dynamo-electric machines
IPC: H02J7/16
Filed: 1927-10-25
Abstract: 281,620. Renault, L. Dec. 4, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Exciting. - In a 3-brush machine used for accumulator charging on self - propelled vehicles, a resistance is provided in the shunt excitation circuit connected to the third brush, this resistance being introduced, by removal of a plug contact, when the output of the machine is required to be reduced for example when the vehicle is making a long run with the batteries already fully charged. In the form shown, the machine has a series coil 4 in the main charging circuit from the brushes 2, 3 and a resistance 11 is included on the earthed side 9 of the shunt coil 8 connected to the auxiliary brush 7. By means of a plug 14 the resistance is cut out when full output is required and introduced when the output is to be reduced. A fuse is included at 10.

Title: Improvements in or relating to retarding field oscillators
IPC: H01J25/24
Filed: 1952-11-11
Abstract: 728,932. Velocity-modulated tubes. RAYTHEON MANUFACTURING CO. Nov. 11, 1952 [April 8, 1952], No. 28442/52. Class 39 (1). The repeller electrode in a retarding field oscillator tube is constructed at its end nearer the accelerating anode to provide an electrical field which can return to the outer surface of the accelerating anode those electrons which penetrate furthest into the repeller electrode. The tube shown comprises a hollow spheroid cathode 11 heated by a coil 12 and emitting electrons through an anode in the form of a conical member 13 forming part of the wall of a resonant cavity 14 into a hollow cylindrical repeller electrode 15 comprising a tube of insulating material coated inside and outside with conductive material. The tube 15 is mounted so as to be electrically isolated for direct current from the wall of the opening 18 in the cavity 14 but coupled capacitively to the cavity at radio frequency through a virtual short-circuit. Tuning is effected by moving the repeller tube 15 relative to the anode 13 by means of a rod 20 passing through the envelope 10 by way of a bellows 21 which permits the rod 20 to be moved in either of the directions indicated by the arrows 22 and 23. A rod 24 of conductive material is mounted inside the tube 15 and is provided with a terminal 26 for connection to a source of potential which for tuning purposes may be different from that of the tube 15, in which case the rod 24 must be suitably insulated from the tube 15. A spike 25 formed at the end of the rod 24 distorts the repelling field so that those electrons which penetrate furthest into the repeller tube 15 are returned to the outer surface of the anode 13. In an alternative arrangement the repeller electrode is a hollow conductive cylinder and is provided with openings near the end of the wall of the cylinder near the anode to distort the repelling field. The openings may be slots in the wall or may be provided by connecting a short section of tube to the main electrode by a plurality of rods lying in the cylindrical surface of the tube.

Title: Improvements in or relating to pyridinium salts
IPC: A61K31/44
Filed: 1961-08-10
Abstract: The invention comprises a bis-quaternary pyridinium salt of the formula <FORM:0930040/IV(a)/1> wherein X is a monovalent ion or 2X is a divalent ion.  The salt may be precipitated by reacting one mol of Hal-CH2-O-CH2-Hal, wherein Hal is halogen, with two mols of pyridine-4-aldoxime in the presence of a solvent comprising a lower aliphatic alcohol, benzene, chloroform, dichloromethane, or dimethyl formamide.  Compounds in which X is halogen are thus formed; these compounds may be converted into the corresponding bis-perchlorate or succinate by treatment with perchloric acid or silver succinate respectively.  The compounds have a tendency to cancel out an inhibition of acetyl cholinesterase produced by alkyl phosphate and thus may be used to combat symptoms of poisoning by phosphurus compounds. Pharmaceutical compositions containing the compounds may take the form of pills, tablets, dragees, solutions, emulsions, syrups, or injection solutions.

Title: Improvements relating to the production of artificial silk, particularly viscose silk
IPC: B65H54/80
Filed: 1931-10-21
Abstract: Freshly spun artificial silk, such as viscose silk, is withdrawn by a preferably toothed roller and deposited in loose loops into a slowly rotating pot which is perforated and lined with cloths for protecting the threads.  The thread mass is treated in the pot while protected by the cloths by spraying, dipping, or lixiviating with deacidifying, desulphuring, bleaching, washing, sizing, or other liquid.  It is dried in this loose condition and wound from the pot preferably while the pot is rotating, on to a reel or bobbin.  The spinning pot is removable from its driving disc, and may receive in known manner a reciprocating horizontal movement in addition to the rotary movement. Alternatively, the thread falling into the pot may be given a reciprocating movement by means of a moving thread guide or such movement may be given to the godet.  In order to maintain the distance between the godet and the top of the thread cake, the height of the spinning pot and its driving plate may be adjusted. The position of the depositing thread guide is also adjustable. The permeable cloth lining of the pot may be muslin or artificial silk fabric, and it may be in the shape of a bag which can be folded over the top of the spinning cake.  The pots may be sprayed with the treating liquid individually or in column formation.  The pots may be constructed with enlargements at their upper edges, so as to facilitate their assembly in columns.  Each pot may be provided with a perforated cover which fits directly on the spun cake or on the protecting cloth.  After the wet treatments, the pots may be drained or centrifuged and then passed through drying chambers, or when in column form, hot air may be passed through the column from the top or bottom.  Specification 344,751 is referred to.

Abstract: 857,392. Mercury switches. REBAUQUECKSILBER - RELAISBAU G.m.b.H. Sept. 12, 1958, No. 29342/58. Class 38 (5). An electromagnetic relay with mercury contacts in a sealed tube has its components encased in a compound 25 such as an epoxy resin which is moulded around the components so as to hold them in position. A mounting-plate 27 may be cast in position with the assembly or may be secured to a threaded bush (not shown) which is placed in the mould with the other components. The sealed tube has two metal parts 8, 9 separated by resin 10, and to which the connectors 7, 7<SP>1</SP> are soldered. A quartz or ceramic insulator 11 separates the upper end of the part 9 from the cap part 8. The tube is partially filled with mercury 12 in which a magnetic float 13 normally maintains an insulating pot 14 so that the mercury therein, which is in contact with an electrode 15 welded to cap 8, is separated from the mercury 12. When the coil 2 is energized the float 13 is attracted to bridge a non-magnetic insert 17 in the part 9 and the mercury in the pot 14 combines with the mercury 12, to complete a circuit between the connectors 7, 7<SP>1</SP>. The float is guided for vertical movement by an apertured disc 18 engaging the pot 14 and by cams, balls or rollers 16 which bear on the inside wall of the part 9. The part 8 has an inwardly-bent flange 24 which, if there is an explosion within the tube, will engage a shoulder 23 of the part 9 and prevent separation of the parts 8, 9.
