Title: Improvements in or relating to detergent compositions
IPC: C11D11/02
Filed: 1957-07-31
Abstract: A process of making a high-density spray-dried detergent composition from a homogeneous fluid slurry, initially containing entrained air, comprising (a) 40-60 per cent of water, (b) 10-40 per cent, preferably 15-20 per cent, of at least one alkali metal salt of a detergent anionic organic sulphuric reaction product having an alkyl group of 8-22 carbon atoms; (c) 5-25 per cent, preferably 15-20 per cent, of sodium sulphate, the weight ratio of (b) to (c) being in the range of 7-1; and (d) 5-15 per cent, preferably 6-12 per cent, of sodium silicate having a ratio SiO2 : Na2O of 3-1, preferably 1.5-2.0, comprises adding to the slurry at least one non-ionic compound; (e) containing polyoxyalkylene ether groupings and having a molecular weight of 800-11,000, generally in an amount of 1-4 per cent, whereupon the slurry separates into two phases, then agitating the slurry to liberate entrained air, and spray-drying the product. (All percentages are based on the final slurry obtained.  Component (b) may suitably be the sodium salts of alkyl glyceryl ether sulphonates, of fatty acid monoglyceride sulphates or sulphonates, or of the sulphate esters of the reaction product of fatty alcohols with ethylene oxide, but is preferably a sodium or potassium salt of an alkylbenzene sulphonate in which the alkyl group has 9-15 carbon atoms (suitably tetrapropylene), or of a hydrogenated tallow alcohol sulphate, or a mixture of both.  Components (b) and (c) are generally present in approximately equal proportions.  Component (e) may be an ethylene oxide condensate with polypropylene glycol, with an alkylphenol in which the alkyl group has 6-12 carbon atoms, with the reaction product of an excess of propylene oxide and ethylene diamine, or with an aliphatic alcohol having 8-18 carbon atoms. After the entrained air has been liberated, but before spray-drying, alkali metal tripolyphosphate may be added to the slurry with the minimum incorporation of air. Carboxymethylcellulose, commercial mixtures of fatty acids, tarnish inhibitors, fluorescent brightening agents, perfume, colour, and sodium carbonate may also be incorporated before spray-drying.  Specifications 416,379, 596,560, 614,044 and 645,129 are referred to.

Title: Improvements relating to circuits for generating unidirectional voltages in television receivers
Inventor: GARGINI ERIC JOHN
IPC: H04N3/18
Filed: 1953-09-03
Abstract: 767,264. Rectifying. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Aug. 18, 1954 [Sept. 3,1953], No. 24337/53. Class 38 (2). In a television receiver means are provided for generating a unidirectional voltage in response to the return strokes in a beamdeflecting circuit thereof, the voltage generating means comprising a ringing inductor 30 which, in conjunction with the stray capacitance 36 of an output valve 4, is excited into oscillation in response to the return strokes of the beam, rectifying diodes 32, 33 being used to rectify the positive and negative half-cycles of the oscillations to produce a unidirectional voltage which is greater than the amplitude of the oscillations.. The circuit forms a voltage doubling arrangement, the unidirectional voltage being developed across a condenser 34 and taken off via a smoothing resistor 35. The operation of the part of the circuit associated with the scanning coils 1 is described in co-pending Specification 767,263 to which reference is made in the Specification.

Title: Improvements in or relating to television and like systems, and circuits therefor
IPC: H04N5/08
Filed: 1934-08-24
Abstract: 443,031. Television receivers. LANCE, T. M. C., PUGH, D. W., and BAIRD TELEVISION, Ltd., 58, Victoria Street, Westminster. Aug. 24, 1934, No. 24399. [Class 40 (iii)] In a television or like receiver of the kind in which the synchronizing signals at line and picture frequencies for controlling oscillators associated with the deflecting coils of a cathode-ray tube are separated by a valve circuit including elements, such as a capacity and a choke or transformer, having different impedance-frequency characteristics, the valve or valves are so biassed as to separate the picture signals from the synchronizing signals by grid current rectification, while the synchronizing signals produce negative impulses on the grid. In the arrangement shown in Fig. 1, the valve 1 is fed with picture and synchronizing signals by way of condenser 2, grid resistances 3, 4 and limiting resistance 5, the junction of resistances 3, 4 being connected through high resistance 6 to the positive of the high tension, so that the grid is biassed positively with respect to the cathode. The picture signals tend to increase, and the synchronizing signals to decrease, this bias, so that only the latter appear in the anode circuit, where separation of the two frequencies is effected by condenser 11, resistance 7, and transformer 8. A modification, Fig. 2, employs two valves 12, 18 arranged in parallel and biassed so as to cut out the picture signals, a choke 16 being associated with the anode circuit of valve 12 to pass the lower or picture frequencies via condenser 14 to one oscillator, and a resistance 23 and condenser 22 being associated with the anode circuit of the valve 18 so as to pass the high or line frequencies to the other oscillator. Specifications 320,639, [Class 40 (iii)], and 436,108 are referred to.

Abstract: 480,024. Magazine gramophones. LOWE, A. E. BOWYER-. Sept. 16, 1936, No. 25275. [Class 40 (ii)] The unplayed records are supported on a table 28 with a central spindle 35 and are transferred successively to the turntable 27 by a feed-arm 1, mounted for rotary movement on a vertical shaft 4, and provided at its free end with a rotatable arm 24, the end of which carries a pin 25 which engages with the central hole of the topmost record to effect transference thereof, and is disengaged therefrom, when the record is in position on the turntable, by a rod 12 which tilts the arm 1 upwardly about a horizontal pivot 2. One end of the rod 12 is connected to a projecting lug 14 of a bracket 15 mounted below the arm 1 and forming a bearing for the shaft 4, and the other end is connected to a rod 18 sliding longitudinally within the feed arm and having a rack portion 19 which engages with a pinion 23 attached to the arm 24. The combined pivoting movements of the feed arm 1 and the short arm 24 result in a substantially parallel motion of the feed pin. When the record is positioned correctly on the turntable, the end of the rackbar 18 contacts with an adjustable stop at the end of the feed-arm, further lateral movement of which causes the feed arm to be lifted to disengage the feed pin from the record, as described previously. The feed-arm is then rotated into a neutral position intermediate the turntable and magazine, and the supporting spindle 4 is raised by means of one of two cams 29, 30, and a pivoted follower 31. The oscillatory movements of the feed arm are imparted by an eccentric 43 which actuates a horizontal rack member 47 in engagement with an elongated pinion 49 at the lower end of the spindle 4. During the transference of a record to the turntable, the feed arm 1 is positively coupled with the spindle 4 by means of a pin 6 at the end thereof which engages with a bracket 3 in which the pivot 2 is mounted, but during the return movement of the feed-arm, the latter is resiliently coupled with the spindle 4 by means of a spring 7 connected to the pin 6 and the bracket 3. The feed-arm may be rotated about the pivot 2 for adjustment by a screw carried by the bracket, and engaging with the undersurface of the feed-arm.
