Title: Improvements in and relating to the testing of radar apparatus
Inventor: BRADSELL PETER
IPC: G01S7/40
Filed: 1958-08-01
Abstract: 924,208. Radar. A. C. COSSOR Ltd. Aug. 4, 1959 [Aug. 1, 1958], No. 24945/58. Class 40 (7). In an arrangement for testing pulse radar apparatus of the type adapted to indicate moving objects only, energy from the apparatus 11 (Fig. 1) is received at a predetermined position 15 and there, prior to being reflected back to the apparatus 11, subjected to a phase modulation by means of a device 17 to simulate a moving target. In one embodiment the device 17 consists of a waveguide 18 (Fig. 2) provided with a load impedance comprising the series arrangement of a resistor 20 and a crystal diode 21 connected across two opposite walls of the waveguide. By varying a voltage supplied between terminal 22 and the waveguide casing (i.e. the voltage across the diode) the impedance of the load and hence its absorption of energy may be varied to vary the phase of the energy reflected back to the apparatus 11. To check the operation of the apparatus with respect to a fixed target the load impedance 20, 21 is made fully absorbing and a peg 23 of conducting material then determines the level of the reflected energy. Fig. 3 shows a second embodiment in which the required phase variation to simulate moving targets is produced by rotation of a two vaned metallic paddle 24, 25 in the waveguide 18. In other arrangements for producing phase variations in the received energy the waveguide 18 is dispensed with and a rotating paddle, or the parallel combination of four crystal diodes across which a varying voltage is supplied, is positioned at the focus of reflector 15 (Figs. 4 and 5, not shown). The variation of the voltage control in the cure of the impedances employing crystal(s) is preferably effected by a square-wave signal of one half the repetition frequency of the pulses transmitted by the apparatus 11.

Title: Manufacture of non-woven fabrics
IPC: D21F11/00
Filed: 1965-06-14
Abstract: 1,118,045. Papermaking; non-woven fabrics. KALLE. A.G. 14 June. 1965 [16 June, 1964], No. 24977/65. Heading D1R, D2A and D2B. Non-woven fabrics are made by distributing fabric-forming fibres that consist of or include synthetic fibres in a dispersion in an aqueous liquid of a gas or water-immiscible liquid, introducing the mixture on to a fluid-permeable support for the fibres and removing liquid through the support. The synthetic fibres may be of polyester, polyamide, polyvinyl chloride, polyvinylidene chloride, polyolefine or polyurethane. These fibres may be used separately or mixed with one another or with natural cellulosic fibres, wool, leather fibres, or fibres of regenerated cellulose or inorganic materials, e.g. glass, asbestos or slag wool. The fibres may differ in length and may be crimped or capable of being shrunk or crimped. They may be of, e.g. triangular, star-shaped, elliptical or H- shaped cross section. Some of the fibres may be capable of being rendered adhesive by heat or a swelling agent. The dispersion medium may also contain solids, e.g. pigments, binders in the form of dispersions or latices, a polymeric binder in the dissolved state, or a dispersing and thickening agent. Dispersing agents referred to are: potassium oleate and morpholine polyacrylate, and thickening agents are: polyvinyl alcohol, polyethylene oxide, gelatine and methylcellulose. Two or more layers may be deposited separately on the support, and the fibres of the successive layers may differ in length or titre. The water-immiscible liquid may be toluene, chlorobenzene or Diesel oil; or the gas may be air, nitrogen or carbon dioxide, which may be generated in situ, e.g. by dispersing the fibres in a solution of a carbonate or an acid, and then adding an acid or a carbonate respectively, or steam which may be generated by raising the temperature or reducing the pressure. The fluid-permeable support may be a woven or knitted fabric or fleece, which is not detached from the deposited layer or layers. A further such support may be superposed on the deposited layer or layers and a further deposition step carried out. As shown, water containing finely dispersed air or oil and dissolved additives is fed from inlet 21 to a mixer 20 with stirrer 23. Fibres are added at 22. The suspension 39 is deposited on an endless travelling belt 25 of sieve fabric via a regulating valve 38 and a distributor 24. The liquid is run off into a drain funnel 26 and a suction funnel 27. An endless belt 31 of sieve fabric presses the web. Thickening and dispersing agents are removed by a spray 34, the wash-water from which drains down a funnel 28 to clean the return run of belt 25, and then passes out through funnel 35. Rollers 33 and 36 help the removal of suspension medium. The web is passed through a drying channel 37 and removed at 40. For materials of high weight per unit area, the sieve fabric rises in the direction in which it runs. The product can be reinforced by needling, sewing, quilting, polymeric binders or the addition of fibres capable of adhesion by heating.

Patent GB-318620-A (GB)
Title: Improvements in controlling devices for automobile and the like brakes
IPC: B60T15/04
Filed: 1929-08-20
Abstract: 318,620. Bosch Akt.-Ges., R. Sept. 7, 1928, [Convention date]. Fluid-pressure. - The housing of a disc valve controlling a fluid-pressure brake cylinder is rigidly connected with the foot-operated brake lever and the valve is manually controlled by a member connected to the brake lever and receiving the effort of the driver, and the parts are so arranged that the valve under the influence of the braking air pressure and atmospheric pressure maintains the brake pressure duct closed if the member connected to the brake lever is not loaded by the effort of the driver in any operative position. The apparatus shown utilizes the vacuum in the induction pipe of an internal-combustion engine. The foot-pedal 12 is resiliently mounted on a plate 11 fixed to a tube 7 adjustably mounted on the pedal lever 4. A spindle 10 guided by a disc 11<1> bears on the plate 12 and enters the tubular spindle of the valve 17 which it operates by means of a spring 18 bearing on an adjusting .screw 19. The valve spindle is guided in a bush 20 in the tube 7. The valve 17 closes an aperture 23 leading to the suction chamber 25 when the foot-pedal 12 is not loaded. The connection from the chamber 30 to the brake cylinder consists of a flexible pipe led along a cable connecting the brake piston to the pedal lever and connected to a nipple on the head of the piston. Application of the foot to the pedal 12 moves the valve to close the air inlet 29 and opens the chamber 30 connected to the brake cylinder to the suction chamber 25. The brake piston is connected to the pedal lever 4 which is connected to the brakes, so that the brakes are operated and the lever 4 and valve housing are moved, so that if the foot is maintained stationary the valve opens again to admit air to the cylinder. The brake mechanism return spring then moves the lever 4 and valve casing to again close the air inlet 29 and open the brake cylinder to suction. This sequence of operations produces a practically uniform brake power till the foot is further depressed to increase the brake power, or lifted to decrease the power or release the brakes. The stroke of the valve 17 can be adjusted by adjustment of the position of the valve seat 29. The plate 12 is pressed into contact with the plate 11 to obtain direct operation by muscular power. The plate 11 is cut away at the corners to bear on rollers 44 mounted on bolts 43 on the plate 12, which is provided with return springs 15, so that the plate 12 expands to a pressure exerted on any point of its surface without causing a resistance affecting the oscillations of the system. In a modified form, Fig. 3, the valve housing 39 is connected with the brake piston 2 by a rigid tube 37 which also serves as a connecting pipe between the brake cylinder and the valve housing. The end of the tube 37 engages the piston by a hollow spherical joint 36 and the valve housing by means of a hollow part spherical joint secured against thrust and tension. Specification 298,130 is referred to.

Title: Improvements in/or relating to methods of manufacturing anodes for electrolytic capacitors
IPC: B22F7/00
Filed: 1964-06-19
Abstract: An anode for an electrolytic capacitor is made by compacting a mixture of a powder metal, e.g. Ta or Al, and naphthalene around a metallic wire core, heating to expel the naphthalene and then sintering the metal powder.  The metal powder which may be 50 micron size Ta or 20 micron size Al may have an anodized oxide layer. Sintering is effected in vacuum at 650 DEG -659 DEG C. for Al and at 1900 DEG C. for Ta. A final sintering for a very short time at the melting temperature of the metal may then be carried out.  The sintered anodes are then anodized.  The core wires may be Al or Ta and the sintered anodes may be impregnated with manganese nitrate which is decomposed to manganese oxide by heating.  The impregnated anodes may then again be anodized and the impregnation and anodizing may be repeated another three times. A graphite coating may then be applied and finally a metal layer. The Ta is anodized in 0.01% HNO3 for 20 hours and the Al is anodized in an aqueous solution of 2.5% by weight of potassium acid phthalate at 21 volts.

Title: Improvements in or relating to the manufacture of mixed water gas and distillation gas from fuels of volatile content
IPC: C10J1/213
Filed: 1927-09-27
Abstract: 279,059. Humphreys & Glasgow, Ltd., (Assignees of Chrisman, C. S.). Oct. 13, 1926, [Convention date]. Producers.-Combustible gas comprising a mixture of distillation gas and carburetted water gas is obtained by blasting the lower part of a fuel bed, making an up-run through the fuel bed. carburetting and fixing other gas by heat stored during the blasting and passing the carburetted gas and the water gas from the up-run through the upper part of the fuel bed to generate coal gas which is mixed with the other combustible gases. Two generators 1, 2 are blasted in parallel, the blast gases traversing the gasification zones 11 only, and passing through superheaters 3, 4 and regenerators and carburettors 5, 6, to which air is supplied to support combustion, before leaving by stack valves 29. A down-run is then made on one generator, say 1, and an uprun on generator 2, and, by suitable adjustment of the valves, the water gas from the generator 1 passes through conduit 17 to the regenerator chamber 25 and carburetting chamber 24 of the carburettor 6 from which the gas and oil vapours pass to and are fixed in superheater 4 before entering by conduit 14 the generator 2 where they mix with the up-run water gas and distil the fuel in the upper part of the generator; the mixed gases pass through conduit 20 to condensing apparatus and storage. 'The steam runs are now reversed and an up-run made in generator 1 while a down-run is made in generator 2, the gases taking a path similar to that described but through the alternative fixers and carburettors. In a modified process, after the parallel blast and during a down-run on generator 1, steam is admitted by pipe 32 to vessel 5 and passes through heater 3 to generator 1 and is used in the gas making, in this case it is necessary to make the next step a parallel blasting before the alternative operation is commenced. Supplementary gas from storage may be admitted through pipe 31<b>. In the apparatus shown in Fig. 4, the generator 2<a> is blasted upwards and and gas passes directly into superheater 4<a> and is burned therein, the hot gases passing through the carburettor 5a to the stack 18<a>. During the run, steam is admitted to the base of the generator, the water gas going through the carbonization zone 3a, gas being simultaneously drawn from storage through pipe 20<a>, carburetted in chamber 5a, fixed in superheater 4a and passed together with the water gas through the carbonization zone to the wash box 8<a> and storage. A down-run is then made, the water gas passing by conduit 13<a> to the wash box and storage. Steam or water may be admitted by pipe 28<a>.
