Title: Improvements in or relating to stencil duplicating inks
IPC: C09D11/02
Filed: 1953-03-26
Abstract: Water-based tinctorial stencil duplicating inks contain complex double salts of a compound of high molecular weight, e.g. cellulose esters or ethers, proteins, polysaccharides, polyalkyl acrylates, styrene-maleic anhydride copolymers, caseinates, lignates and alginates, in which one of the salt-forming components is ammonium and the other is a metal capable of forming an insoluble salt with the high molecular compound, e.g. copper, nickel, cadmium, zinc, iron or aluminium.  On transfer of the ink composition through the stencil openings to the impression medium to form the copy, the ammonia component is removed by volatilization on drying to leave the corresponding highly insoluble bivalent metal salt of the bodying agent.  Specified bodying agents are zinc ammonium polyacrylate, copper ammonium methyl methacrylate, aluminium ammonium ethyl acrylate, cadmium ammonium carboxy methyl cellulose, zinc ammonium carboxymethyl cellulose, zinc ammonium caseinate or alginate, iron ammonium pectate, copper ammonium alginate, aluminium ammonium alginate; the salts should be added in sufficient amount to give a composition having a viscosity of 35-150 seconds (Stormer Viscosimeter), e.g. 1-15 per cent by wt. of the composition of salts of polyacrylates or 0.5-10 per cent of complex alginates. Colouring agents specified are Nigrosine, triphenylmethane, Rhodamine B, thioflavine, auramine, sulphonated triphenylmethane, quinone imide and xanthene dyes; sodium sulphonate derivatives of nitro-azo, pyrazoline, quinoline, triphenylmethane, diphenyl naphthyl methane, azine, xanthene, and anthraquinone groups; pigments specified are lamp black, malachite green, iron blue, cadmium yellow.  Wetting agents may be added, e.g. dioctyl ester of sodium sulphosuccinate, quaternary ammonium compounds, sulphonated ethers, fatty alcohol sulphonates, polyoxyethylene derivatives of fatty acids; polyhydric alcohols, e.g. glycols, and alkylolamines may be added as humectants. Insolubilization of the bodying agents may be further increased by the addition of aldehydes, e.g. glyoxal or pyruvic aldehyde.  The examples specify the following aqueous mixtures: Example 1 5 per cent Nigrosine J (water-soluble dye), 2 per cent wetting agent (dioctyl ester of sodium sulphosuccinate, 50 per cent solution), 1.5 per cent glyoxal (30 per cent solution), 35 per cent ethylene glycol, 56.5 per cent zinc ammonium carboxy methyl cellulose (2.5 per cent solution in water); Example 2 5 per cent Nigrosine J (water-soluble dye), 1 per cent wetting agent, 1.5 per cent glyoxal (30 per cent solution), 35 per cent ethylene glycol, 57.5 per cent zinc ammonium polyacrylate (2.5 per cent solution in water); Example 3 15 per cent Aquablac (40 per cent carbon black dispersed in aqueous medium), 1 per cent wetting agent, 30 per cent ethylene glycol, 3 per cent zinc ammonium alginate, 51 per cent water.  Specifications 676,373, 742,301 and 752,337 are referred to.

Title: Improvement in carburettors
IPC: F02M7/11
Filed: 1924-04-03
Abstract: 213,919. Griffon, G. April 7, 1923, [Convention date]. Spray carburettors.-A partial vacuum is produced in the float chamber by connecting such chamber to the mixing chamber by a passage which is controlled by a port in a movable choke tube connected with the throttle valve in such a manner, that the passage is fully open in the closed position of the throttle and vice versa. The choke tube may also be provided with additional ports to admit supplementary air when the communication with the float chamber is closed. The float chamber space 1 communicates through a restricted orifice 2 with a chamber 3 open to the atmosphere at 4 and connected to the mixing chamber 7 by a passage 5. This passage is controlled by a port 12 in a choke tube 6 connected to the throttle valve 9. The aperture 4 may be controlled by a valve or be fitted with interchangeable plugs of different bores. The choke tube may have ports 12, Fig. 2. to register with supplementary air ports when the passage 5 is closed. According to the Specification as open to inspection under Sect. 91 (3) (a), the space 1, Fig. 1, (Cancelled) communicates with the mixing chamber 6 through an orifice 2, chamber 3 and a conduit 5 which is controlled by a valve 7 normally lifted by a spring 8, and adapted to be closed bv an arm 10 on the spindle of the throttle valve 9 as the latter approaches its fully open position. The chamber 3 communicates with the atmosphere through an orifice 4 which may be adjustable by a needle valve or replaced by others of different bore. The closing movement of the valve 7 may also be limited. In the construction shown in Fig. 3 (Cancelled) the conduit 5 is not controlled, variations of suction being obtained by controlling an air admission to chamber 3 by a valve 7a actuated by the throttle valve. The valve 7a may be replaced in a modification bv a ported extension of the throttle, valve spindle. In the modification shown in Fig. 6, (Cancelled) the control device 3, 4, 5, 7. 10 is shown in connection with the means 19 for controlling the suction in the float chamber described in Specification 191,140. The throttle valve actuating lever may be formed in one with the arm 10 and connected to the throttle valve spindle through a helical spring, so that the valve 7 or its equivalent, may be actuated only after the throttle valve has reached its fully open position which is determined by a stop. The choke tube 6 may be actuated by suction, and the valve 7 or its equivalent by the speed regulator of the engine. This subjectmatter does not appear in the Specification as accepted.

Patent GB-1072019-A (GB)
Title: Improvements relating to space satellite communications systems
IPC: H04B7/204
Filed: 1966-02-28
Abstract: 1,072,019. Space satellite communication systems. G. BATTAIL, and P. BROSSARD. Feb. 28, 1966 [Feb. 27, 1965], No. 8706/66. Heading H4L. The invention is concerned with a communication system, comprising a plurality of land transmitters and receivers utilizing a common space satallite repeater. Each transmitter transmits over the same frequency band and communication is by means of frequency modulation. Allocation of a receiver to a particular transmitter is brought about by adding a distinctive frequency to the communication signal to produce a composite signal and frequency modulating the carrier of the transmitter by said composite signal. The allocated receiver is rendered insensitive to all signals other than that which is frequency modulated by a composite signal comprising said distinctive frequency. At the transmitter station 1, the communication signal at 11 is added in network 12 to a much larger amplitude signal of distinctive frequency F 1 . The produced composite signal, frequency modulates the output of oscillator 15 in modulator 14, to produce a signal which is transmitted to the satellite 2. At the satellite, the carrier frequency is changed and the signal retransmitted to the receiver station 3. At the receiver station, the signal is passed, via a frequency changer 32 to a reception threshold reducing frequency demodulator 33, which has the property of only being sensitive to signals having a low rate of change of frequency. The output of the demodulator 33 is fed to receiver output 34, and also to a filter 35 which selects the frequency F 1  and passes it to a high-gain amplifier 36. The output of the amplifier at frequency F 1 , frequency modulates, in modulator 38, the output of oscillator 37. The resultant frequency modulated signal is passed to the second input of frequency changer (mixer) 32. The result is that the frequency modulation in the received signal due to the added frequency F 1  is cancelled out, and only frequency moduation due to the communication signal appears at the input to demodulator 33 and only the communication signal appears at output 34. The frequencies F 2  . . . F n  allocated to other transmitter/receiver station pairs and the corresponding frequency deviations, are so chosen that reception of a signal with an identifying frequency modulation frequency F 2  say produces, at the input to demodulator 33, a beat frequency (F 2  - F 1 ) frequency modulation, with an instantaneous rate of change of frequency so high that the demodulator is insensitive thereto.

Title: Improvements relating to step-by-step mechanism
IPC: G05G5/02
Filed: 1933-07-15
Abstract: 413,613. Locking levers. ELECTRICAL APPARATUS CO., Ltd., and PARTRIDGE, H. R. C., Vauxhall Works, South Lambeth Road, London. July 15, 1933, No. 8718/34. Divided on 412,046. [Class 80 (iii).] Relates to mechanism for providing a step - by - step motion, such, for example, as is described in Specification 320,458, [Class 80 (iii)], and comprises a single pawl and a rack having teeth with camming and arresting surfaces in which the camming surfaces of adjacent teeth deflect the pawl alternately to either side of a neutral line n-n. which is the track which would be followed by the nose of the pawl in the absence of the teeth of the rack. The rack comprises sets of teeth 5 and 8 shaped as shown, and the pawl plate 11 is mounted on a pivot carried by a pivoted arm 13 slotted at 15 to engage the part to be operated, such as an arm of an electric starter. The pawl 12 in meeting a tooth 8 is constrained to follow the path shown by the circles a, b; it is then thrown against the part 7 of a tooth 5 by a coil spring 23 and stops there. If the operator eases the forward pressure on the carrier 13 or slightly withdraws it, the pawl follows the path c, c<1>, c<2>, c<3>, until arrested by the part 10 of a tooth 8. To allow the pawl to ride over the teeth on the return movement, the pivot 21, Fig. 3, of the plate 11 is made tapered, and a coil spring is interposed between a yoke 20 and the plate. The ends of the spring are located one on each side of projections 27, 28. Projection 27 is fixed to the rack and projection 28 is on the plate 11 so that oscillations in the plane of the paper are resisted by the spring, which also resists rocking movements about the pivot. The device is particularly applicable to the operating gear of an electric motor starter.

Title: Recoiling closure for shelters against heavy explosions
IPC: E04H9/12
Filed: 1950-04-12
Abstract: 672,415. Shelter closures. MESNAGER, J. April 12, 1950 [April 15, 1949], No. 9042/50. Class 20(iii) A closure for a shelter intended to resist heavy explosions consists of.a rigid body of considerable size such as a solid block 1 of concrete adapted to limitedly yield to the shock caused by an explosion and means. to cushion the momentum acquired by the closure in the course of its recoil. As shown, the block is of slightly less crosssection than the tunnel 2 which it closes, and is carried on trucks 3 with wheels or rollers 4 running on tracks 5. Liquidoperated jacks 6 at the side of the block or in the tunnel wall are connected through a pipe system 7 to a pressure tank 8 controlled by a valve. The closure moves in the tunnel in the manner of a piston, and the entrance is cleared by hauling the block on to a siding or a side chamber by cables and a windlass. When the block recoils because of an explosion, the movement is cushioned by the friction of the jacks and of the rest shoes 15 which limit the sag, of springs 16. By arranging a retractable bulkhead 14 behind the block 1, the air compressed between the bulkhead and the block serves to return the block to its initial position. This, return movement can also be achieved by means of an inclined guide surface, springs, or a cylinder with a piston adapted to compress a gas or liquid. The rolling movement may be replaced by a sliding movement, e.g. the block may be supported on a liquid interposed between the block and a slab founda. tion and limited by liquid-tight flexible joints. The recoil, movement instead of being rectilinear may be a circular translation or a rotation about a suitable axis.
