Abstract: 900,199. Frequency changing. STANDARD TELEPHONES & CABLES Ltd. March 2, 1961, No. 7591/61. Class 40 (6). A crystal mixer 12 is held in a coaxial mount comprising an outer cylinder 10 attached by means of a flange 14 to mounting-block 15 which is soldered to one element 16 of a strip line. The central conductor of the crystal engages a pin 11 passing through insulators 20, 25 and an aperture in the line element 16, and which is coupled to the other line element 18 by means of a fixed condenser comprising plates 21, 22 and dielectric 23. The shunt capacity between the pin 11 and line element 16 is made variable by means of a variable condenser comprising conductive disc 24 attached to the pin, dielectric washer 25 and a movable element comprising slider 26. Slot 27 in slider 26 prevents contact with the pins 10, and the slider may be held by means of a clamp 28. The arrangement is such that the crystal mount is inductive and resonates at the working frequency with the fixed and variable condensers which form an adjustable impedance-matching network.

Abstract: 384,991. Alternating-current commutator motors. SIEMENS-SCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. March 12, 1931, No. 7694. Convention date, March 14, 1930. Void [Published under Sect. 91 of the Acts]. [Class 35.] Sudden changes of speed of shunt commutator motors driving knitting and similar machines are obtained by switching operations which alter the ratio between the potentials of the commutator and the secondary or stator windings. Figs. 1 to 4 show connections of a rotor fed motor giving respectively hyper-synchronous, synchronous, sub-synchronous and very low speeds required in the operation of a knitting machine and the necessary changes of connection may be effected by the cam chain of the machine. The main speeds may be varied by means of a resistance 3, Fig. 1 in the secondary winding 1. In a modification, the ends of the secondary winding are connected to separate brush sets which are adjustable for speed regulation. In the case of a stator fed motor, Fig. 7, the commutator brushes are also connected to the mains through an adjustable transformer 7. Alternatively the brushes may be connected to a tapped transformer winding on the stator through an induction regulator. Further speed variations may be obtained by varying the number of poles of the motor.

[Also in Division G5] In rewinding mechanism which may be applied to cine film, magnetic tapes or other webs, the spool in magazine 2 is driven initially at high speed until the web is nearly re-wound, and then an element 38 sensitive to a reduction in web tension reduces the re-winding speed. The spool is driven by a side-wheel 11 engaging, through an intermediate roller 12, a wheel 13 whose shaft carries a rubber faced disc 15 opposite a parallel, but axially off-set similar disc 27. Disc 27 is driven through gears 25, 26 by motor M and a variable speed driving transmission between the discs is provided by an axially slidable friction roller 28 carried on an arm 30 pivoted at 31, and spring-loaded at 33. Fast re-wind from spool 6 is started by depression of button 34 to pivot arm 30 and so move rollers 28 to the periphery of disc 27, arm 30 thus being retained by the spring-loaded rod 37 engaging dog 36. The end 38 of rod 37 rides on the web or film F until tension falls and arm 30 is released to pivot back to the low-speed position of roller 28. This position is determined by stop 40.

Title: Process for the manufacture of sulphinic acid derivatives
Filed: 1938-03-15
Abstract: 509,804. Sulphinic acid amides SCHERING AKT.-GES. March 15, 1938, No. 8039. Convention date, March 27, 1937. Samples furnished. [Class 2 (iii)] Sulphinic acid amides of therapeutic value are obtained by the reaction of aromatic sulphinic acid halides, substituted by at least one nitro or acylamino group or halogen atom, with ammonia or a primary or secondary amine. The sulphinic acid halides used as starting materials may be obtained by the action of thionyl chloride on the sulphinic acids, which are themselves obtainable by reducing the corresponding sulphonic acid halides, e.g., with stannous chloride in alcoholic solution or with an alkaline solution of sodium sulphite. In the examples, (1) p-nitrobenzenesulphochloride is treated in alcoholic solution with stannous chloride to yield p-nitrobenzenesulphinic acid, which is converted into its chloride by reaction with thionyl chloride ; the chloride is then treated with ammonia in ethereal solution to yield p-nitrobenzenesulphinamide ; (2) o-nitrobenzenesulphinic acid chloride is produced from the acid and thionyl chloride, and is treated with ammonia in ethereal solution. Reference is made also to (a) the production in similar manner of pacetylaminobenzenesulphinic acid amides, from which p-aminobenzenesulphinic acid amides are obtainable by saponification, suitably in the presence of a reducing agent, (b) the reaction of o- or p-nitrobenzenesulphinic acid chloride with sulphanilic acid amide, and (c) the reaction of the sulphinic acid halides with aminopyridines and aminoquinolines. Samples have been furnished, under Sect. 2 (5), of products prepared from p-nitrobenzenesulphinic acid chloride and (1) dimethylamine and (2) 2-aminopyridine. The Specification as open to inspection under Sect. 91 states that the sulphinic acid halides may contain as substituents hydroxy groups, groups convertible by hydrolysis into hydroxy groups, mercapto groups, carboxylic and sulphonic acid groups, amino groups and arsenic acid groups. It refers also to the reaction of the sulphinic acid halides with alkylamines, anilines and glucosamines. This subject-matter does not appear in the Specification as accepted.
