Title: Improvements relating to the production of regenerated cellulose fibres
Inventor: MAHOMED RAMON SIDICK
IPC: D06P5/22
Filed: 1961-03-14
Abstract: A water-soluble reaction product made by heating epichlorhydrin and a polyamide containing secondary amine groups is incorporated in regenerated cellulose fibres, preferably by incorporation in the viscose prior to spinning, although alternatively the spun fibres may be treated with the polyamide-epoxy resin reaction product before drying.  The polyamide may be a reaction product of a polyalkylene polyamine, e.g. diethylene triamine, triethylene tetramine, tetraethylene pentamine or dipropylene triamine, or mixtures thereof, with a dicarboxylic acid, e.g. adipic, azelaic, or diglycollic acid or mixtures thereof.  A portion of the polyalkylene polyamine may be replaced by a diamine.  Preferably the water-soluble polyamides contain the recurring groups -NH(CnH2nHN)x-CORCO-where n and x are each 2 or more and R is the divalent organic radical of the dicarboxylic acid.  Conventional regenerating baths containing sulphuric acid and sodium and zinc sulphates are used.  Fibres so made may be dyed with wool dyes (see Group IV(c)).  Specification 930,132 and U.S.A.  Specifications 2,926,116 and 2,926,154 are referred to.ALSO:Regenerated cellulose fibres having incorporated therein a water-soluble reaction product made by heating epichlorhydrin with a polyamide containing secondary amine groups are dyed with wool dyes.  The polyamide-epoxy resin reaction product may be used in proportions of 0,5-10%, based on the cellulose content of the viscose.  In an example, fibres were dyed in an AzoGeranine 2GS sulphuric acid bath to a full solid shade after 1 hour, which was not reduced by prolonging dyeing under acid conditions for a further 3 hours, while exhaustion after 4 hours was 72%. Preferably the reaction product is incorporated in the viscose prior to spinning, although alternatively the spun fibres may be treated with the polyamide-epoxy resin reaction product before drying.  The polyamide may be a reaction product of a polyalkylene polyamine, e.g. diethylene triamine, triethylene tetramine, tetraethylene pentamine or dipropylenetriamine, or mixtures thereof, with a dicarboxylic acid, e.g. adipic, azelaic, or diglycollic acid or mixtures thereof.

Patent GB-241241-A (GB)
Title: Starting apparatus for electric motors
IPC: H02P1/20
Filed: 1924-04-14
Abstract: 241,241. Cousins, R. W. April 14, 1924. Master control systems. - In a starting apparatus depending on a two-position master controller, resistance contactors close automatically in succession under the control of a transformer and relay, which have a mutual action in retarding the steps of acceleration. The transformer has two oppositelyacting winding primary windings 68, 66 of which one is in series with the motor and the other in shunt across the supply conductors. The secondarv winding 67, by induction from rising current in the series primary 68, transiently excites the relay coil 26 which controls in turn the electromagnets 145 of the starting-resistance contactors. The immediate response of the relay attracts two spring-restrained armature-levers 32, 33. The lever 33 opens a contact 56 which weakens the contactor magnet by putting in a resistance 165, and simultaneously both levers co-operate by their lower cranked ends to maintain equal pressure on opposite sides of a pivoted hang-down member 47. When the rising motor-current steadies and the armatures begin to return, the movement of the lever 33 is retarded bv an inductive shading-coil 27 while the unretarded movement of the lever 32 deflects the hanging member, which makes a circuit through contacts 52, 53, and thus shorts a resistance 174 in the shunt coil of the transformer primary. The effect is to prolong the transient inductive energization of the secondary coil for an additional period. When both armatures have returned, the contact 56 is reclosed, the magnet of the contactor is fully energized and the corresponding step of the starting resistance is cut out. A similar mutual action of the transformer and relay takes place at each step of the starting period. The transformer coils are disposed as shown in Figs. 8 and 10 inside a closed laminated magnetic yoke 57.

Title: Improvements in and relating to multi-range electrical measuring instruments
IPC: G01R15/00
Filed: 1945-04-16
Abstract: 600,274. Resistance, inductance, and capacitance measurements. MUIRHEAD & CO., Ltd., and LISTER, W. C. April 16, 1945, No. 9489. [Class 37] In a multi-range instrument, particularly a universal bridge, the switching means is associated with means adapted to disclose through windows in a panel inscriptions showing.the state in which the switching means has been set, the factor by which the readings are to be multiplied, and the units in which the measurements are made. In the universal bridge shown in Fig. 1 the main balance impedance is controlled by three knobs K1, the position of which at balance gives the figure in the measurement before multiplication. A knob K2 controls the circuit switching for selecting the type of measurement, and has three positions corresponding to inductance, capacitance, or resistance measurements. A knob K3 controls a range-changing switch which selects the factor by which the reading of the knobs K1 is to be multiplied. Three further knobs K5, K6, K7 control impedances the magnitude of one of which gives the quadrature balance for indicating the " Q " of an inductance or the dissipation factor " D " of a condenser. The particular impedance which gives balance and consequently the knob K5, K6, or K7 to be used is selected by a knob K4 controlling a selector switch. The range change knob K3 carries a dial 1 with three concentric rings of figures. Above this dial is a sliding plate S1 engaged in guides 2, as shown in Fig. 2, with three windows SL6, SL7, SL8. Above this plate is the panel 3 with a window SL2 in it into register with which one or other of the windows SL6, SL7, SL8 will be brought. The sliding plate S1. is moved by an arm 4 attached to the knob K2, for each of the three positions of which one of the windows SL6, SL7, SL8 in the plate S1 registers with the slot SL2 in the panel so that one number on the dial 1 is visible, indicating the multiplying factor to be used. The plate 8 is furnished with inscriptions " Ohms," " Microfarads," and " Henrys " so positioned that the appropriate one is visible through a window 6 in the panel 3 according to the position of the knob K2. A second sliding plate S2 is moved by an arm 8 on the knob K2 and is engraved with letters " D " and " Q " in certain predetermined positions. With the knob K2 in the resistance position no letters are visible through windows SL3, SL4, SL5 in the panel. A third sliding plate S3 formed with windows SL9, SL10, SL11 slides over the plate S2 and is operated by an arm on the knob K4, which controls a switch selecting a particular impedance used for measuring " D " or " Q. " The arrangement is such that the letter " D " or " Q " is visible opposite the particular knob K5, K6, or K7 that controls the impedance for the corresponding measurement.

Jackets and covers.-A tyre casing is built up from plies of a rubbered fabric 1 - - 6, Fig. 7, assembled as a flat band over an expansible drum 13, the edges of the band being turned over to form the tyre beads (with or without endless retaining-wires 17) and the band shaped to arched cross-section by the application of a lateral pres. sure at the edges and outward radial pressure at the intermediate portion. The fabric layers of which the cover is built up consist of parallel threads held together by unvulcanized rubber, or by a weak weft thread at intervals. Strips of such fabric with the threads arranged obliquely are laid successively on the mandrel, with the threads of adjacent layers crossed, and to provide for even tension in the threads, the fabric strips are cut at graded angles to compensate for the increasing cross-section of the cover during the building-up process. Fig. 16 shows (approximate. ly) the necessary variation in the obliquity of the threads in the layers 1 - - 6 of a 36in. by 4¢in. cover having threads .04in. thick on a rubber backing. 007in. thick.
