Title: Production of dyestuff pigment pastes
IPC: C09B67/46
Filed: 1936-12-22
Abstract: Aqueous pastes of azo dye pigments are obtained by working up the dry pulverulent pigment into an aqueous paste with a quaternary ammonium or phosphonium or ternary sulphonium compound containing an aliphatic or cycloaliphatic residue of more than 5 carbon atoms.  Specified quaternary ammonium compounds are dodecyltrimethylammonium chloride, stearyldi (b -hydroxyethyl) methylammonium methyl sulphate, stearylpyridinium chloride, oleylpolyglycoldimethylammonium methyl sulphate and trimethylammonium acetic acid dodecyl ester chloride. In an example, dry pulverulent Hansa yellow 5G is pasted with an aqueous solution of stearylpyridinium chloride and the paste, diluted with water, is allowed to stand overnight and passed through a sieve, the paste is applicable for use, with a usual substratum, as a size colour.  Specification 424,672 is referred to.ALSO:Dye preparations.-Aqueous pastes of azo dye pigments are obtained by working up the dry pulverulent pigment into an aqueous paste with a quaternary ammonium or phosphonium or ternary sulphonium compound containing an aliphatic or cycloaliphatic residue of more than 5 carbon atoms.  The pigments so treated may be either (a) lakes obtained by precipitating azo dyes from aqueous solution by means of precipitating agents such as barium chloride in presence or absence of substrata, or (b) admixtures of water-insoluble azo dyes with substrata.

Inside the case is a frame 17 made of spring metal wire which is U-shaped and has a central limb 18 and two side limbs 19, the free ends of the limbs 19 being disposed adjacent the mouth of the case. The frame is secured in the case by two metal clips 22 secured one over each of the opposite corners of the mouth and a reinforcing strip of leather or like flexible material is interposed between the frame and the case and is secured to the case by adhesive. The central limb 18 of the frame has a loop which forms the anchorage 26 to which is connected a chain forming the attachment means 27, the other end of which has a ring 28. The edge portion of each side 11 at the mouth of the case is folded inwardly to enclose a strip metal spring which is normally straight and which must be bent by the pressure applied substantially parallel with the side to open the case. The clips 22 serve to secure the springs in position.

Band; actuated by springs and weights; electric and magnetic. -One end of a brake band is connected to a spring or weight S, Fig. 1, and the other to a lever E<1> or other actuating-device. In the " off " position the spring draws a part D<1> on the end of the band against a stop d1, and there is no tension of the band. In the " on " position the lever E<1> engages with a stop F<1>, the part D<1> is drawn away from the stop d1 and the tension on the band is determined by the spring or weight S and is uniform. The spring or weight S may be connected directly to the band or through a lever or the like. Fig. 3 shows an arrangement in which the brake is operated by the movable core E of a solenoid, which, in the " on " position, is drawn into engagement with a fixed core F. The connecting- link a2 is bifurcated, and the link a3 passes through the fork, carries an adjustable stoppiece D, and is encircled by the spring S.

Title: Improvements in or relating to carrier demodulators
Inventor: MATTHEWS ROBERT
IPC: H03D1/10
Filed: 1954-12-10
Abstract: 789,168. Phase-sensitive circuits. DECCA RECORD CO., Ltd. Dec. 7, 1955 [Dec. 10, 1954], No. 35894/54. Class 38 (4). [Also in Group XL (c)] The amplitude and phase sense of a modulated carrier is detected by pulse sampling the carrier at short intervals of time corresponding to the same phase of the carrier frequency, then integrating the pulses in a Miller valve circuit with capacitive negative feedback and whose time constant during the sampling pulses is made small so that it rapidly follows any sudden change of amplitude or reversal of phase. As shown, the carrier is applied through a cathode follower valve 12 and second cathode follower 18 to a diode bridge gate 20-23 rendered conducting by positive or negative switching pulses synchronous with the carrier frequency so that the instantaneous amplitude of the carrier is applied to the grid of a Miller integrator valve 24, whose integrated output applied through a cathode follower 42 measures the amplitude and phase sense of the carrier. Alternating current negative feedback is also applied from the anode of the integrator valve 24 to the grid of the cathode follower 18 so that the difference of the two inputs to its grid is very small and the sampling pulses may be of small amplitude. Further, D.C. negative feedback is applied from the output 43 through a cathode follower 52 to the mixer cathode follower 18 to stabilize its D.C. level. Equal positive and negative H.T. voltages energize the valves to render the output symmetrical. The output D.C. level may be varied by varying the D.C. bias applied back to the valve 18 from a potentiometer 46 having a constant voltage drop across it derived from a gaseous circuit tube 45 in the derived from a gaseous tube 45 in the cathode circuit of the valve 42. The circuit may be used in # sweep radar P.P.I systems for detecting the amplitude and phase sense of the quadrature voltages respectively induced in the stator coils from the rotor. Specification 679,723, [Group XL (c)], is referred to.

Abstract: 619,376. Adjusting radio apparatus. PHILIPS LAMPS, Ltd. Dec. 5, 1946, No. 36012. Convention date, July 9,1943. Addition to 617,098. [Class 40 (v)] The system for setting a circuit element, such as a slidable electrode condenser, to a number of predetermined positions by means of an associated follower member co-operating with an adjustable turret of pre-set screws, described in the parent Specification, is modified so that screws found to be unsatisfactory may be removed without stripping the assembly. This being effected by making the two discs carrying the screws relatively adjustable, the removal of the screws being possible only at an off-normal relative setting of the discs. As shown, follower 14 of condenser 15 is spring urged into contact with screws 7, which are mounted in threaded and smooth bore holes in adjustable discs 23 and 9 respectively. Bushes 11 are provided on screws to limit the distance through which the screws can be adjusted. In order that the screws may be readily removed the holes in disc 9 and an associated ring 30 are made larger than the diameter of bushes 11. Normally, the disc and the ring are given a relative angular displacement, so that the screws cannot be withdrawn, but can be brought into alignment by loosening a screw 26 to enable the screws to be withdrawn. The detent mechanism described in the parent Specification is employed.
