Title: Improvements in or relating to permanent waving and similar treatment of the hair
IPC: A61K8/46
Filed: 1949-08-17
Abstract: A composition for permanent waving or similar treatment of hair comprises a reducing agent, an alkaline substance to give the composition a pH value greater than 7, and an aluminium compound soluble in the alkaline composition.  The composition is preferably employed in solution at a pH of 9-9.5 which may be obtained by means of a weakly alkaline substance such as ammonia. The aluminium compound may be aluminium tartrate.  An aluminium salt which is rendered soluble in the alkaline composition by the addition of tartaric or citric acid or other organic compound containing hydroxy groups may be used.  The reducing agent is preferably one which contains a mercapto group.  If the mercapto compound contains an acid group such as a sulphonic or carboxylic group, a water-soluble aluminium salt of that compound may be used.  The composition may be prepared in solid form if desired. Perfumes, wetting agents, dyes, alcohols, glycerine, or acetone may be added to the composition.  In an example, 7 grams of thioglycollic acid are dissolved in 50 c.c. of water.  To this is added a solution of 3.5 grams of crystalline aluminium sulphate and 3.5 grams of seignette salt in 30 c.c. of water, and the total volume is adjusted to 100 c.c. by adding water, after adding 15 c.c. of strong ammonia.  In another example, seignette salt solution is added to aluminium sulphate solution and the pH is adjusted to 7-7.5.  The solution is then atomized by hot air and the water is evaporated leaving a white powder.  The sodium salt of a mercapto-butane sulphonic acid is mixed with the powder. The mixture is dissolved in water with the addition of ammonia to give a permanent-waving solution.  The solution may also be used for straightening naturally curly hair.  Hydrogen peroxide or bromates may be used for the subsequent fixing.

IPC: B29C35/08
Filed: 1936-08-05
Abstract: <PICT:0479492/IV/1> <PICT:0479492/IV/2> Foils or bands of a highly polymerized organic thermoplastic material are contacted when in a non-plastic state and free from volatile solvents with one or more surfaces heated highly enough to render the foils or bands plastic, and they are drawn without application of pressure over the heated surface and stretched. The thermoplastic material may be a cellulose derivative such as benzyl cellulose, or a polymerization or interpolymerization product of vinyl chloride, styrene, vinyl carbazole, an acrylic ester or a homologue thereof, or after-chlorinated polymerized vinyl chloride.  Halogenated and hydrohalogenated rubber are excluded.  The foils may be coated with talc, metal oxides, or other solids or liquids in order to prevent them sticking to the heated surface, or they may have scratched surfaces.  Cylinders or drums may serve as heated surfaces.  Towards the ends they may be of reduced diameter with arched surfaces.  The foils may be stretched transversely as well as longitudinally.  They may be used for electrical insulation purposes, e.g. in condensers, or for thermal insulation particularly in cr<\>zeped form, or as packing material, adhesive films, or coverings.  Small bands may be stretched into fine threads, and these may be used for the production of yarns, or used for upholstering.  As shown in Fig. 1, foil 2 from roll 1 is supplied by rubber-covered rolls 3 to the heated rotatable cylinder 4 and is converted on the latter into a thermoplastic state. The speed of cylinder 4 may be different from that at which the foil is supplied.  The foil is stretched by the winding drum 5 which has a higher speed than the conveyer rolls 3.  The heated cylinder 4 is dusted with talc by a coated asbestos wool pad 6.  Two or more heated cylinders may be used, and the foils on leaving the hot surfaces may be cooled.  The foils may be stretched longitudinally and transversely by endless bands 9 provided with steel points 10.  In examples, foils of after-chlorinated polyvinyl chloride, polystyrene, a mixed polymer of vinyl chloride and an acrylic ester, and polyvinyl chloride are passed over a heated cylinder and stretched while plastic.

Title: An improved hydraulic steering gear for ships
IPC: B63H25/22
Filed: 1954-07-27
Abstract: 760,863. Ship steering gear. DONKIN & CO., Ltd., PAULIN, W. S., and HALL, F. T. June 30, 1955 [July 27, 1954], No. 21838/54. Class 114. In a hydraulic steering gear for ships in which the steering wheel 11 operates a reversible pump 10 to force hydraulic fluid through one or other of two conduits 12, 13 to one or other of two rams 14, 15 actuating a tiller bar 16, a non-return valve is disposed in each conduit to prevent reverse flow from the ram to the pump and the valves are coupled together so that when the pump forces one valve open to feed the associated ram, it also opens the other valve to permit return flow from the other ram to the pump. A block 23 houses both valves, each being housed in a cylindrical bore formed with a restricted neck 24 against the lower face of which a conical non-return valve 28 is urged by a spring 27. The inlet to the bore is at the restricted portion 24 and the outlet is through the lower part or chamber 26. In the upper part 25 of the bore a piston 30 rests through a stem 29 on the top of the valve 28. A conduit leads from the restricted portion 24 to the space above the piston of the other valve so that when the pump forces fluid past either valve 28, the fluid also acts on the upper surface of the piston of the other valve forcing it down to open its associated valve and provide a return passage to the pump. On top of the block 23 is a cam 43 which can be turned by a handle 44 to depress a plate 41 resting on stems 40 contacting the pistons 30 and open both valves to provide free flow in both directions.

Title: System for modulating a carrier wave by a digital data signal and reproducing the data signal
IPC: H04L27/02
Filed: 1974-05-17
Abstract: 1436918 Digital transmission; amplitude modulation TOKYO SHIBAURA ELECTRIC CO Ltd 17 May 1974 [28 May 1973] 22188/74 Heading H4P [Also in Division G4] A system for modulating a carrier wave having a sine or quasi-sine waveform and substantially constant frequency and amplitude by a digital data signal and reproducing the data signal comprises an arrangement (see Fig. 1A) in which the carrier wave is defined into a plurality of blocks and all the cycles but one at least within each block are subjected to amplitude modulation, and a demodulator (see Fig. 2A) for reproducing the digital data from a recorded or transmitted modulated signal including an element 20 for comparing the amplitudes of the unmodulated and modulated cycles within each block and a device 46 responsive to the output of comparator 20 for reproducing the digital data. In operation, in the amplitude modulator of Fig. 1A, the input carrier waves are squared at 2 and applied via a flip-flop F 0  to a ring counter 3 to define the carrier into a plurality of blocks. In each word of the modulated output, modulation of the carrier by the digital data applied to 1C to a data memory 4 is preceded by modulation of the carrier by a head forming signal. Modulation is effected by closing of a switch 10 by the head forming signal or by the output of a logic gate circuit 5-7 applied via an OR gate 13. In the demodulator or reproducer (see Fig. 2A) the modulated signal is applied to a zero cross detector 19 and a clock pulse generator 26 to produce clock pulses. A comparator 20 compares the amplitude of the modulated signal with a reference signal level derived in circuit 21 by rectifying the peak value of the modulated signal. The output of the comparator 20 is applied to the signal input of a shift register 36 periodically shifted by the clock pulses. The modulation data is reproduced by an arrangement including AND gates 41a-41d and a data memory in response to a set pulse from generator 39. In the alternative embodiment of Fig. 3A (not shown) comparison is effected twice in respect of reference signals derived from the negative as well as the positive peaks of the unmodulated signal for developing the input signal for the data extraction circuit. In a further embodiment Fig. 3A (not shown) the diode 27 is replaced by an FET. Each block of the carrier wave may include two or more cycles wherein one or more cycles may be modulated by one or more bits. Alternatively, the negative and positive halves of a cycle may be modulated by separate bits. The modulated signal may be transmitted via a telephone line, or phototransmission or by further modulation of a subcarrier in an FM broadcasting signal.
