Patent GB-134230-A (GB)
IPC: C04B18/02
Abstract: 134,230. Fried, A. Nov. 19, 1915, [Convention date]. Stone, artificial; concretes; compositions containing oils, resins, etc; stone, colouring; stone, hardening.-An aggregate for making artificial stone is made from fine waste materials such as slag, infusorial earth, earths, ground stone, sand, ashes, fibres, sawdust, and a binding-material, such as lime, cement, gypsum, glue, oil, resin and lyes from paper or soap making or from the extraction of dyewoods, and is formed into particles of any desired shape or size. The particles, before drying or after being dried and coated with a binding-material, are placed loosely together in layers so as to form blocks or stones, having a cellular structure and containing air cavities. Spherical forms produce the maximum volume of cells. Colours may be added. Pieces of aggregate of different colours may be employed to obtain a variegated product. The outer cavities may be filled with substances to vary the colour, surface hardness, &c. The aggregate pieces may be produced by shaking, by extrusion or other presses, by two grooved plates working at any angle to one another, by knives &c., or the material may be passed through a vibrating sieve in the form of grains. The Specification as open to inspection under Sect. 91 (3) (a) states also that the cells may be filled with coloured or other substances. Pieces of aggregate which do not bind well may be treated with gypsum, cement, water-glass and the like to make them firmer or to increase their speed of drying, or hot air, steam, or gas may be employed for this purpose. The aggregate pieces of the finished product may be heated to any desired degree and may even be melted or " coagulated." The cellular nature may be increased by the use of materials which are gasified at a high temperature. Ores may be treated in the manner described prior to their further treatment, in which case the additional materials for the further treatment may be employed as binding agents for the aggregate pieces. The particles formed by passage through a vibrating sieve may thence be fed to a. conveyer which may be in the form of a swinging shoot on which the pieces roll and are made to assume a more or less spherical form, or if a vertically vibrating conveyer band be used the pieces are flattened. The pieces may be roughened bv the use of roughened shoots which are oscillated, jerked, or otherwise moved. Fig. 3 (Canceled) shows in cross-section a shaking-device in which the aggregate are made to assume a round or granular form. The materials are placed upon a sieve-like surface 1 fixed in a frame 2 which is suspended or otherwise supported and is oscillated by a crank 5 and is shaken by contact with buffers 4. This subject-matter does not appear in the Specification as accepted.

Title: Process for the manufacture of oxide sulphide and haloid cathodes for electric discharge devices
IPC: H01J9/04
Filed: 1929-05-01
Abstract: 313,151. Vereinigte Gl³hlampen und Electricitõts Akt.-Ges. June 8, 1928, [Convention date]. Vacuum tubes.-Alkaline-earth cathodes are prepared by coating a core, e.g. of tungsten or molybdenum, with the oxide, sulphide or halide of a refractory metal, such as tungsten or molybdenum, or with a compound, or a mixture of compounds which when heated, yields the oxide, sulphide or halide of the refractory metal, the alkaline earth metal being then deposited by vaporization from the electrodes. Preferably the compound is applied to the core in solution in water or other solvent, appropriate compounds being ammonium tungstate. sulpho-tungstate, or molybdate. When heated to 500‹C these compounds produce tungsten oxide, tungsten sulphide and molybdenum oxide respectively, the gaseous products being pumped out of the valve envelope. After the treatment with the alkaline earth metal, the cathode is heated to about 1500‹C for a short time. Ammonium tungsto-oxyfluoride may be employed to produce a haloid cathode.

Title: Improvements relating to soil stabilization in the construction of roads and other extended surfaces exposed to weather
IPC: C09K17/48
Filed: 1954-05-11
Abstract: 755,887. Soil stabilization. RITTER, E. A. May 11, 1954 [May 26, 1953], No. 13668/54. Class 68(1) A surface layer of clay-containing soil is stabilized in situ by intimately incorporating therein a solution of sodium resinate, and then, a solution of calcium chloride to cause a precipitation of metallic resinate about the soil particles, the quantity of the solution of calcium chloride supplied being in excess of the quantity necessary to ensure that all the sodium resinate in the soil is reached and precipitated. The surplus hygroscopic calcium chloride helps to maintain the water content of the soil at an optimum value. To prevent the formation of dust the surface of the stabilized soil is either coated with bituminous material, or heavily impregnated with hygroscopic calcium chloride or sodium chloride. Dependant upon the soil conditions, the strength of the solution of sodium resinate is one part of resinate of soda in about 50 to 500 parts of water, and the quantity of such a solution sprayed on to the soil is sufficient to permit of the precipitation of resinate solids to the extent of one part to approximately 500 to 1500 parts by weight of soil. The solutions are sprayed on to the soil, which may be churned up and compacted by soil-working implements.

Title: Improvements in or relating to low-frequency correcting circuits for wide-band amplifiers
IPC: H03F1/50
Filed: 1963-04-05
Abstract: 955,466. Valve and transistor amplifying circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. April 5, 1963 [April 9, 1962], No. 13669/63. Headings H3T and H3W. In an arrangement for correcting loss of lowfrequency response in an R.C. coupled amplifier an auxiliary amplifier t, Fig. 4, is connected in series with the load resistor Ra of the main amplifier T1, its control electrode being connected via a resistor R to the output electrode of the main amplifier and via a capacitor Cg to earth. As shown, thermionic valves are used, but the arrangement is equally applicable to transistor circuits (Fig. 5, not shown). In operation the auxiliary valve t acts at higher frequencies as a cathode follower, its grid being earthed over capacitor Cg, and so the cathode impedance which is part of the anode load of the main amplifier T1 is low. At low frequencies the capacitor Cg no longer acts as an effective earthing path and cathode-follower action tends to cease; the cathode impedance of valve t thus rises and so increases the load on the anode of the main amplifier valve T1. The Specification gives mathematical expression for the relationships between the component values for a flat overall response. It also describes a wide-band amplifier which also includes top-peaking coils L1, L2, Fig. 6. In this embodiment the lowfrequency response may be controlled by means of a variable resistor R<SP>11</SP> in series with the anode load resistor R<SP>1</SP> of the amplifier T1; in addition the grid of the auxiliary valve is biased by a potentiometer R2, R3 and its anode decoupled by means of resistor R1 and capacitor Cz.

Title: New or improved process and apparatus for finishing fabrics
Inventor: TAYLOR EDWARD PERCY
IPC: D06C15/14
Filed: 1948-05-22
Abstract: 669,985. Finishing fabrics. BLEACHERS' ASSOCIATION, Ltd., TAYLOR, E. P., MELVILLE, A., and LOCKERS (ENGINEERS), Ltd. June 22, 1949 [May 22, 1948], No. 13898/48. Class 42 (i). Textile fabric is subjected to the action of a vibrating beater while it is supported on a base and moved across the path of the beater, the vibratory movement of the beater being controllable and comprising an electro-magnetically actuated movement away from the fabric and against the action of a resilient means, and a reverse movement towards the fabric under the influence of at least the resilient means, continuously repeated in rapid succession, and adjustment of the positioning of the beater with respect to the fabric being possible. As shown, cloth wound on a beam 12 is beaten by a beater 31 which is the full width of the cloth and has a hardwood surface 32. Beater 31 is integral with an armature 29 supported by leaf springs 30 from a frame 15 carrying an electromagnet 13. Frame 15 is slidable in guides 16 and is suspended from cables 21 via resilient tension boxes 20. Cables 21 are adjustable vertically by means of a hand wheel 28 to control the proportion of the weight of the frame and beater assembly which is transmitted to the cloth. Beam 12 is rotated during beating by direct gearing 34; alternatively a roll of cloth may rest on, and be driven peripherally by, a rotating roller. As a further alternative, cloth may be treated continuously as it passes over a rubber-faced roller on the way from a supply roll to a takeup roll; the facing on the beater may in this case be of rubber or rubber-like synthetic plastic. The beater may operate at 1000 or more beats per minute (e.g. 3000 per minute when the frequency of electric current supply is 50 cycles per second). The length of stroke of the beater may be between about <SP>1</SP>/ 16  and <SP>1</SP>/ 3  inch. If necessary, a side-to-side movement may be given to the cloth beneath the beater. Cloth may be treated while dry or moist, or when impregnated with dyestuffs &c. Heat may be applied before or during the beating operation. A fabric coated with rubber or rubber-like plastic may be interposed between the beater and the cloth, or between the cloth and the support, or both, for example by confining the cloth between two endless bends of such fabric or by treating the cloth in roll form in which layers of cloth and rubbercovered fabric alternate. Existing beetle machines may be converted by substituting a high-frequency vibrating beating mechanism for the usual beetle fallers.

Abstract: 876,552. Cam-operated switches. AGFA A.G. May 1, 1958 [May 18, 1957], No. 13923/58. Class 38 (5). [Also in Group XX] An optical objective is focused by remote control by means of electrical switches 52, 53 which operate electromagnets to drive the objective in two directions. The hand-operated switch which operates switches 52, 53 comprises a hand wheel 42 having two pawls 47, 48 which are urged by springs 49, 50 into engagement with the teeth of ratchet wheels 45, 46 respectively. Fixed to ratchet wheels 45, 46 are star wheels 43, 44 which serve to operate switches 52, 53 respectively. Therefore rotation of the hand wheel 42 clockwise causes wheel 43 to rotate (while wheel 44 remains stationary) and open and close switch 52 to move the objective in a series of steps in one direction. Rotation of hand wheel 42 in an anticlockwise direction causes the objective to move in the opposite direction.

Abstract: 696,327. Gas meters. NORTH THAMES GAS BOARD. June 12, 1952 [June 12, 1951], No. 13927/51. Class 54 A dry gas meter with sliding valves is provided with external means for displacing the valves in such a manner that each outlet port of the valves is brought into direct communication with the meter inlet so that gas may pass from the latter to the outlet ports of the valves without passing through the measuring chambers. In the event of failure, the meter may thus be by-passed to maintain essential services. Where the meter is fitted with valves of the kind having an arcuate sliding movement, each valve 8 may be lifted from its seat by a cam 16 so that the inlet chamber formed above the valve plate 1 of the meter communicates with the outlet ports. The rotation of the cams is limited by a portion 19 and effected by a shaft which may be arranged for operation by a key or wheel from a locked or sealed compartment outside the meter. The cam may be fitted with a cross bar to lift two valves simultaneously. To prevent the by-pass from being reset, the operating shaft may be fitted with a non-return ratchet, or where a separate cam is used for each valve, each cam may have a notch 16a to lock with the underside of the valve once the latter has been lifted. Rectilinearly operated valves are fitted with lifting rods or loops for engagement by cams mounted on the operating shaft.
