Title: Process for decorating glazed surfaces
Inventor: BOWMAN JOHN LAWRENCE
IPC: C03C17/06
Filed: 1960-11-09
Abstract: 907,368. On glaze decoration. HEATHERLEY FINE CHINA Ltd. March 30, 1961 [Nov. 9, 1960], No. 38470/60. Class 56.  A process for the " on glaze " decoration of china comprises covering that part of the surface which is to be kept free of decoration with  a resinous film, applying paint containing lustre Colours or precious metal over that part of the surface to be decorated and at least over the edges of the surrounding film and subjecting the surface to firing temperatures. The film may be applied as a resin/solvent solution, the solvent being allowed to evaporate after application, or a previously formed film may be attached to the surface with size or gum arabic. Alternatively, a film may be applied to the usual " cover coat transfers," or screen printing techniques may be used in which case the paper is split after printing and the film transfer applied to the surface with an adhesive, then the backing paper is washed off leaving the film adhering to the surface, The precious metal or lustre colours are applied as paints or varnishes optionally using a flux, e.g. bismuth flux.

Title: Improvements in or relating to light metal pistons
IPC: F16J1/04
Filed: 1958-11-28
Abstract: 846,819. Casting composite pistons. SCHMIDT G.m.b.H., K. Nov. 28, 1958 [Dec. 4, 1957], No. 38527/58. Class 83 (1). [Also in Group XXVI] A piston 1 of light metal is provided, with cast-in heavy metal rings 2, 3, embedded in the body of the piston in such a way as to be movable radially in a direction at right angles to the gudgeon-pin axis, but not in the direction of such axis. The rings are mounted above and below the gudgeon-pin axis and, as shown in Fig. 3, are formed with web portions 15 firmly embedded in the piston. The rings are so arranged that in the region at right angles to the gudgeon-pin axis, a gap 13 is left between the ring and piston. In operation, when the piston is cold, the outer surfaces of the freed portions contact the cylinder wall 4, and clearance 14 is provided between the cylinder wall and piston, but as the temperature of the piston increases and expands the latter into a close clearance with the cylinder wall, the constraining effect of the web portions 15 causes the rings to be deformed, and thereby provides a clearance 6 between the rings and the wall. The freed portions of the rings are prevented from axial movement by interengaging lugs cast alternately in the piston and inner surfaces of the rings. In the embodiment shown in Fig. 4, the rings are circular and are freed around their entire circumference, but are prevented from movement at portions adjacent the gudgeonpin axis by stirrup-shaped members 17, or lugs 16 embedded in the piston. In a further embodiment (Fig. 6, not shown) the rings are circular and of trapezoidal cross-section so that when the piston cools during the casting process, clearance is formed between the ring grooves and the flanks of the rings, thereby permitting freedom of movement of the latter, both in the radial and axial directions. The rings are again anchored in the region of the gudgeon-pin axis. To prevent binding of the rings during the working expansion of the piston, they may be made oval, or relieved in the region of the gudgeon-pin bosses.

Abstract: 950,263. Electromagnets. ELEMAG-ANSTALT. Oct. 12, 1962 [Oct. 12, 1961], No. 38685/62. Heading H1P. [Also in Division F2] The stem 3 of a two or threeway ball or slide valve 2 is sealed by a bellows 27 and attached to an armature 4 having an annular rib 4a of frustoconical section which co-operates with a complementary annular groove in a fixed pole member 13. The valve is loaded to the closed position by an adjustable holical or pneumatic spring or, as shown, a stack of spring discs 19. The electromagnetic winding 15 is energized by a current which is a function of temperature, e.g. of the liquid controlled by the valve. The temperature is measured by a resistor 32 with a negative temperature coefficient which resistor, with fixed resistors 33, 34 and a variable resistor 35 forms a bridge, the input to which is connected to a transformer secondary winding 41 via a full-wave rectifier 39, a resistor 38 and a condenser 40. The bridge output is connected to the winding 15 through a transistor amplifier 46, 47, 48 supplied from another transformer secondary winding and diodes 49. A magnetic amplifier may be used instead of the transistor. A linear relationship exists between the excitation current and spring force so that the degree of valve opening is determined by the level of excitation of the electromagnetic winding.

In a gas cooled nuclear reactor, fracture of the fuel element jackets is detected from observation of the radio active content of the gas. The concentration of the short-lived fission products in the gas is determined by the number of solid, positive ions into which they disintegrate and which are collected on a given sector of the periphery of a rotatable drum. Each reactor is exposed first to the contaminated gas and then to a scintillation counter. In one embodiment, the gas decay chamber and the detector are mounted round the drum periphery so that a given surface area passes from the chamber to the detector during rotation of the drum. In other embodiments, the drum is elongated, the chamber and the detector are mounted adjacent along its length and movement of a given area of the drum periphery between the chamber and detector is effected by longitudinal movement of the drum. The drum is moved along its length to scan a number of consecutive areas and is then turned to expose a further set of areas along its length. The drum longitudinal displacements are effected by worm gearing and the rotation about the axis by either gearing or a cam at each end. Specification 851, 328 also is referred to.

Title: Improvements in solidified liquid fuels and compositions for cleaning fabrics
IPC: C10L7/02
Filed: 1930-12-31
Abstract: In the preparation of solidified fuels by the formation of a framework-like mass in a liquid fuel, the hydrocarbons contained in the latter consist of at least 70 per cent of saturated aliphatic hydrocarbons containing 7 to 10 carbon atoms not having more than three methyl groups substituted in the chain.  The remaining hydrocarbon content may consist of up to 30 per cent of saturated aliphatic hydrocarbons containing 5 or 6 or 11 to 13 carbon atoms, or of monocyclic hydroaromatic hydrocarbons, or up to 20 per cent of aliphatic hydrocarbons containing 13 to 16 carbon atoms, or 10 per cent of aromatic hydrocarbons, or 5 per cent of hydrogenated naphthalenes.  Up to 50 per cent, calculated on the total hydrocarbons, of alcohols containing 2 to 4 carbon atoms may be added.  Small amounts of ketones such as acetone, or terpenes or esters may also be added.  The framework-like mass is formed by reaction in the fuel of a base such as ammonia, soda, or potash upon resin acids such as abietic or pimaric acid or upon higher fatty acids such as stearic or palmitic, or by reaction of ammonia on casein or of aniline and formaldehyde.  The solid fuel may be pressed against a filter diaphragm as described in Specification 339,660, [Class 91, Oils &c.], to separate the liquid free from solid.

Abstract: 1407481 Separating solid particles T C MATHEWS 23 Aug 1972 [23 Aug 1971] 39306/72 Heading B2H An apparatus for separating first and second types of solid particles, e.g. of an ore, the first type of particles having a particular measurable characteristic, comprises means for moving the two types of particles in a uniform path; a sensing means for detecting the measurable characteristic of particles of the first type and for providing control signals; nozzles forming a plurality of flowing fluid streams; and a plurality of means responsive to the control signals for allowing selective impingement of the flowing fluid streams on the particles of the first type to separate the latter from the particles of the second type and each including an actuator coupled with pivotally mounted arcuate means, the actuator being responsive to a control signal for moving the arcuate means from a non-selection position to a selection position for allowing the selective impingement of the flowing fluid stream from a nozzle on a particle of the first type. The apparatus may be used for separating diamond particles from a diamondiferous ore. In Fig. 2, material from which desired particles having a particular characteristic are to be separated is fed by a belt conveyor 10 into a trajectory plane 12 past sensing means 14 comprising a number of individual sensors. A plurality of actuators 16 are linked to pivotally mounted arcuate tubes 18 which in the non-selection mode are positioned to receive streams of liquid from nozzles 22 and to channel them on to a deflecting plate 24. In this mode the material falls along the trajectory plane 12 and into a receptacle 26. When a sensor observes a particle which it is desired to separate, it generates a control signal which actuates a corresponding actuator 16 which in turn pivots its associated arcuate tube, thereby allowing the corresponding liquid stream to impinge upon the desired particle causing it to be diverted into the receptacle 28. In Fig. 3, the material is fed, e.g. as a slurry, on to an inclined screen type conveyor 30 above which is located the sensing means 14 for the actuation of actuators 34, 36 linked with respective arcuate tubes 18 pivotable about a rod 48 and associated with nozzles 22 whereby desired particles may be deflected from the conveyor into a receptacle 54 by liquid streams issuing from the nozzles and passing through the conveyor to impinge on the desired particles. The measurable characteristic of the desired particles may be the natural radiation emitted by such particles or the radiation emitted by them after they have been treated with fluorescent material and irradiated. The radiation emitted by the particles is detected by electromagnetic wave sensing means electrically connected to electromagnetic actuators. Depending on the measurable characteristic of the desired particles, colour, reflectivity, radioactivity or thermomagnetic sensing means may also be used.
