Title: Process for carrying out circuit reactions with liquids under relatively high pressures
IPC: F04D13/14
Filed: 1961-05-11
Abstract: 960,890. Circulating systems for high pressure processes. KLEIN, SCHANZLlN & BECKER A.G. May 11, 1961 [May 13, 1960], No. 17264/61. Heading B1X. In a process for carrying out circuit reactions with liquids circulating under relatively high pressures a multi-stage centrifugal supply pump is arranged in the circuit and the pressures of separate intermediate stages of the supply pump are used to prevent the circulating liquid from issuing from the circulatory system either by directly connecting the said separate intermediate stages to the circuit or by connecting the said separate intermediate stages to the shaft seals of a circulatory pump forming part of the circuit. In one form of the process the used liquid issuing from the circulatory system is supplied through a regenerator to a low pressure stage of the supply pump. In Fig. 1 the working liquid passes through pipe a, cooler 2, pressure-raising pump 3 and pipe c to the reaction tank 1. The delivery port of the multistage centrifugal supply pump 4 is connected via pipe d and valve 5 to the circulatory system. The supply pump 4 draws liquid through pipe e from supply tank 6 to which fresh liquid is supplied through pipe f and regenerated liquid through pipe g. The glands of pump 3 are connected to those intermediate stages of pump 4 which have a pressure which, depending on the nature of the liquid in the system, is controllable by shaft seals. Thus by appropriate choice of the intermediate stages of the pump a pressure difference can be produced at the gland, this difference being so low that the gland continues to seal. In Fig. 2 the valve 5 is closed in operation and the supply of the system and the maintenance of pressure in tank 1 are effected by supply pump 4 by way of pipe h. The return pipe b is connected to an appropriate stage of supply pump 4 and they working liquid passes through a number of stages to have its pressure increased as required. The liquid is cleaned in regenerator 7 and supplied through pipe i to a low pressure stage.

Abstract: 435,213. Hair waving. MAEDER, F., 192, North Terrace, Adelaide, Australia. June 13, 1934, Nos. 17525 and 17526. Convention dates, June 13, 1933 and June 5, 1934. [Class 131] Hair is permanently waved by impregnating with a solution of a sulphide, coiling on a curling rod, and then heating to a relatively low temperature, for example, in the case of normal hair, to a temperature of less than about 100‹ C. An alkali, e.g. ammonia, is preferably added to the sulphide solution. The sulphides of the alkali metals, e.g. sodium sulphide, or ammonium sulphide are preferably employed, e.g. a solution of 2À5 parts by weight of ammonium hydrosulphide in 97À5 parts of water. Organic substances forming colloidal solutions or suspensions, e.g. albuminous substances such as keratin, collagenes or gelatin, agar agar, gum arabic, starch, resins, dextrine, shellac or viscose may be added to the sulphide solution. In an example, 100 gms. of keratin are suspended in 500 c.c. or alcohol and the liquid is slowly poured while stirring into 500 c.c. of concen. trated ammonia. 60 c.c. of this solution are then added to 100 c.c. of a 10 per cent by weight solution of ammonium hydrosulphide in water. Before adding to the sulphide solution, part of the keratin may be precipitated from the keratin solution by the addition of a suitable precipitant, e.g. sodium chloride. The heating may be effected by clips heated internally by electrical resistances or by hot water, or by a clip as described in Specification 415,865 which is heated before application to the tress and is allowed to cool whilst in position on the hair.

Title: Improvements in and relating to signal transmitting apparatus
IPC: H04N11/14
Filed: 1953-06-25
Abstract: 747,103. Colour television. PHILCO CORPORATION. June 25, 1953 [June 28, 1952], No. 17649/53. Class 40 (3). [Also in Group XL (c)] In a colour television or like system in which two carriers of same frequency but different phase are amplitude modulated in balanced modulators by different colour or like signals and vectorially combined to produce an amplitude and phase modulated wave a burst of carrier frequency of reference phase is transmitted during the back porch intervals succeeding the horizontal synchronizing pulses by a pulse applied to one of the modulators. As shown, negative-going line synchronizing pulses C from a generator 12 are applied to a differentiating circuit 50, and clipping and polarity reversing circuit 51 to produce triggering pulses E, coincident with the leading edges of the pulses C, applied to a flip-flop circuit 52 to produce output pulses F terminating after the pulses C. The pulses F are then differentiated to produce pulses G, which after clipping and polarity reversal produce pulses H coincident with the trailing edge of pulses F, which act on a further flip-flop 55 to produce finally pulses I commencing after the synchronizing pulses C but whose duration (determined by the flip-flop 55) is less than the back-porch interval. These may be additively combined by a double triode circuit 31 with one of the colour signals P1 and applied to a balanced modulator 32 also fed with sub-carrier frequency from a generator 38. The other colour signal P2 is applied to a second balanced modulator 36 fed in phase quadrature from the sub-carrier generator 38 and the two balanced modulator outputs additively combined, across a common anode resistance of the modulator valves, in a circuit 16. Dynamic clamps 40, 41 between the generator 12 and modulators 32, 36 ensure that during the blanking intervals the modulators are balanced although unbalanced during modulation. Further a part of the output pedestal pulse I from the flip-flop 55, equal to one half the pulse amplitude, may be added in the combiner 16 to raise the D.C. level of the sub-carrier burst so that the oscillation extremes are limited to the amplitude range of the synchronizing pulses. In a modification the pulses I are applied directly to the modulator 32 without first being combined with the colour signal P1.
