IPC: C09B49/10
Filed: 1927-05-02
Abstract: 270,348. Soc. of Chemical Industry in Basle. April 30, 1926, [Convention date]. Addition to 109,360. Sulphuretted dyes are produced by sulphurizing, in the presence of urea and an aromatic base or derivative thereof, the indophenols obtained by condensing carbazol or an N-alkylcarbazol or mixtures thereof with nitrosophenol. According to one example the indophenol obtained by condensing carbazol and nitrosophenol is sulphurized by means of sodium polysulphide and sulphur, urea and carbanilide being then added. The mass, after drying and baking, is ground and extracted first with dilute sodium sulphide and then with hydrochloric acid. The dyestuff dyes cotton blue in a hydrosulphite bath. In a second example, the indophenol obtained by condensing a mixture of N-ethyl carbazol and carbazol with nitrosophenol is sulphurized as before and to the mass are added sulphur, urea, and the symmetrical urea obtained from o-toluidine. The dyestuff is worked up as in the first example and dyes cotton greenishblue tints from a clear hydrosulphite. bath. Benzidine, aniline and acetanilide are also mentioned as suitable bases that may be added together with the urea. to the sulphurized mass. Specifications 234,681 and 243,739 are referred to.

Title: Improvements in or relating to signalling systems
IPC: H03M1/00
Filed: 1947-05-02
Abstract: 630,095. Secret transmission. WESTERN ELECTRIC CO., Inc. May 2, 1947, No. 11874. Convention date, July 9, 1945. Addition to 630,094. Drawings to Specification. [Class 40 (iv)] [Also in Group XL (c)] A signal transmission system comprises means for determining at predetermined intervals the amplitude of a signal wave, means for building up by steps an electrical quantity proportional to the predetermined amplitude and means for transmitting a series of pulses defining each electrical quantity thus built up. At the receiver, a corresponding quantity is built up, conducting devices being selectively conditioned by the pulses of a series, to change the voltage due to a constant current in a load, each by a fixed fraction of a voltage which represents the maximum amplitude of the signal wave. Output pulses are then produced of amplitude proportional to the voltage across said load. The circuits described are similar to those of the second embodiment of the invention described in the parent Specification, the difference being that the controlled attenuators for building up the electrical quantity representing the signal amplitude by varying the gain of amplifier stages are replaced by controlled conductances of the same form as the attenuators and shunted across a line.

Abstract: 332,536. Musgrave, J. L., and Crittall, R. G. April 18, 1929. Ventilation apparatus. - In a ventilating system for buildings or large halls in which air is supplied from a main duct to a series of ventilating gratings or openings, a stream line shutter is arranged in each branch duct communicating with the ventilating gratings or openings, each shutter being automatically operated and controlled so that intermittent currents of air of varying velocities are created from the different ventilating openings. As shown in Fig. 1, the branch ducts A, B, C are provided respectively with stream line shutters a<1>, b<1>, c<1> each rotated by a small electric motor D acting through a worm gear d'. The shutters are initially set at different angles in relation to the ducts, and the motors are operated from a central station, the current being switched on by a time or other device arranged either to actuate each motor in turn, or the three motors simultaneously. In a modification, the shutters are arranged at the entrance to the ducts A, B, C and are actuated through worm gearing by a single motor. In further modifications, the shutters are regulated by a pegged barrel device, or by a perforated roll or compressed air to keys controlling ' the shutters.

Abstract: 1536834 Magnetically retained switches TOKYO KINZOKU CO Ltd 22 March 1977 [26 March 1976] 12051/77 Heading H1N A magnetically held switch has a magnet 40 with pole-pieces retained in engagement with a conductive soft magnetic member 13 connected between the terminal 7 and fixed contact 19 which co-operates with a movable contact 26 on a spring contact carrier 25 which is pivoted at 53 to a body 35 which carries the magnet 40 on a pivot pin 47 and ispivotally mounted on the housing 1 at 54. A spring 30 acts on end 28 of the member 25 in the direction to rotate it about the pivot 53 and apply contact pressure to contact 26 but on release of the magnet 40 from the conductor 13, the force of the spring 30 causes rotation about part 54 to open the contacts 26, 19 and closure of alarm contacts 60, 62. The switch is reclosable by a plunger 6 engaging the end 27 of the spring 25. The plunger 6 can also be used to open the contacts 26, 19. Release may be due to thermal demagnetization or magnetic opposition on heavy current in the conductor 13.

Abstract: 214,840. Frame, J. May 7, 1923. Furs and the like, beating and cleaning mechanically.-In a machine for burring wool on skins and pelts, the skin is made to traverse a worktable beneath a rotating drum which carries on its periphery a series of parting-blades and beaters so arranged that the beaters strike in the partings made by the blades. The feed-rolls 11, 12 feed the skin forward from the table 10 to the workt.able, which consists of a series of slats or flaps 22 hinged at 23 and supported below by a spring 24 restrained by a bridle 25. The drum is built up of a series of disc sections 49 bolted as at 29. Each disc section carries three peripheral lugs, the leading portions of which are tapered to form blunt curved parting-blades 30. Beaters 31 are attached to the lugs by bolts 32. To ensure thorough treatment of the skin two of the blades and beaters on each disc are slightly offset, one to the right and one to the left, and the sections are so bolted together that the dividers and beaters are located in helical arrangement round the surface of the drum. The beaters 31 may be made with the rear ends closed, or they may be solid throughout. In operation the skin is fed backwards and forwards beneath the drum by the rollers. It is then reversed, and the operation repeated. Suitable gearing enabling the drum roll 11 to be reversed as desired is described.
