Filed: 1974-04-24
Abstract: 1472469 Pigmentary compositions T H FERRIGNO 24 April 1974 [30 April 1973] 17899/74 Heading C4A A pigmentary composition comprises calcined agglomerates, the agglomerates comprising (a) from 70 to 98 parts by weight of anhydrous mineral having a refractive index of from 1À47 to 1À74 and selected from one or more of silica, an alkaline earth metal silicate and an alkali metal or alkaline earth metal alumino silicate, (b) from 1 to 10 parts by weight of an inorganic binder selected from one or more of a soluble silicate, a sodium polyphosphate and an expanding lattice montmorillonite, (c) an opacifying agent which is distributed uniformly throughout the agglomerates and which is an inorganic colorant having a refractive index exceeding that of the anhydrous mineral, the anhydrous mineral being in the form of particles having an average particle size of from 2 to 40 microns which are bonded together in the form of agglomerates ranging in size from 20 microns to 1 centimetre, the specific gravity of the agglomerates being from 60 to 95% of that of the inorganic material in the composition. The "soluble silicate" is an alkali metal silicate wherein the mole ratio of SiO 2  to M 2 O, where M is the alkali metal, is from 1À65 : 1 to 3À88 : 1. The compositions may be prepared by intimately and uniformly mixing together the anhydrous mineral and the opacifying agent, adding the inorganic binder thereto in the form of a solution or dispersion, forming the resultant mixture into agglomerates and calcining the agglomerates. In the examples the compositions are prepared from feldspar, bentonite, water, zinc oxide, zirconium silicate, titanium dioxide, antimony oxide, crimson and black underglaze colours and a synthetic iron oxide.

In a cutting head for an electric dry shaver a stationary grid 1 is pivoted on a grid support 4 and is pivoted away from a movable cutter 3 for cleaning of the grid and the cutter. As shown in Figs. 1 and 3 an end plate 2 of the grid is pivoted on a pin 5 mounted at one end of the grid support and the grid is released by hand pressure on a control lever 6 for movement of the grid under pressure from the cutter, the lever 6 operating a slide against the influence of a spring which urges an aperture in the slide into engagement with a catch 7. In the modification shown in Fig. 4 the end plate 10 is gripped by stationary combs 9 mounted on a resilient strip 8 which deforms on hand pressure on the lever 6 to release the end plate. The invention is stated to be applicable to dry shavers having rotated cutters.

Abstract: 165,795. Hennebutte, H. G., and Goutal, E. July 2, 1920, [Convention date]. Void [Published under Sect. 91 of the Act]. Carbonizing processes.-Materials such as coal, lignite, peat, or schist are subjected to a rising temperature in successive stages in apparatus in which the distillation products are withdrawn at each stage, and the permanent gases and uncondensed vapours from one stage are introduced into the material in a subsequent stage, thereby increasing the yield of gas or other products. For example, in a three-stage process, the acid products of the first or low-temperature stage are fixed in a suitable reagent and the basic products from a second or higher-temperature stage are absorbed in an acid reagent, hydrocarbons being retained by suitable solvents, while the third or high-temperature stage results in the evolution of gases. Gases from an external source may be utilized in like manner. One or more of the intermediate stages may be omitted, causing an abrupt elevation in temperature.

Title: Improvements in heat exchangers
IPC: F28F27/02
Filed: 1948-07-07
Abstract: 667,167. Regenerators heating air for combustion.- SOC. ANON. DE COMMENTRY-FOURCHAMBAULT ET DECAZEVILLE. July 7, 1948 [Feb. 5, 1948], No. 18305/48. Class 64(i) In apparatus for the exchange of heat between gaseous fluids, e.g. metal airheaters or cowpers for blast furnaces heated by gases obtained by combustion of the furnace gas, hot gas is introduced intermediately of an inlet 11 and outlet 13 for the heated gas, situated at the respective ends of a wall through which heat exchange takes place, so that the temperature of the wall between the hot gas inlet part and the heated gas outlet end is kept uniform. In a heatexchanger, Fig. 4, a gas entering at 11 and passing out at 13 is heated by gases, from a combustion chamber 6 and burner 7 for fuel such as pulverized coal, injected at successive points 1, 2, 3 &c.. between baffles 14 by means of distributers D1 D2, D3 etc. which are thermostatically controlled to maintain the heat-exchange walls in the vicinity of the injection points at a uniform temperature as near as possible to the maximum temperature which the material, e.g. metal, of the wall can withstand. The temperature of the gases injected at the point 1 is controlled by the addition of a cold gas, e.g. air, smoke or inert gases from a pump 19 adjusted by a valve 18 controlled by a thermal element on the heat-exchange surface near the point 1. On heavy loads, the later distributers, e.g. Dp-1, may not be used, but on light load the uniform temperature zone is extended since a servo-motor controlled by the last distributer Dp-1, or a thermostat at p' then causes-a decrease in the quantity of combustion gas supplied to the first point 1 and a corresponding increase in supply to the later distributers. In order to avoid the addition of cold gases to the heating fluid, the latter may be pre-cooled in a small heat-exchanger. Each distributer, Fig. 6 (not shown), consists of a slide valve controlling communication between an inlet, e.g. from a previous distributer, and two outlets, i.e. a port connected to the injection point and a port to the next distributer. The slide is actuated by an oil pressure operated piston, the oil supply to which is controlled by a thermostat subject to the temperature of the heatexchange wall at the injection point. As shown in Fig. 7 the uniform temperature is obtained by the heating gases entering at 26 and flowing first of all generally in the same direction as the heated fluid, then re-entering at 29 to flow generally in counter-flow to the fluid to be heated, which enters at 32 and leaves at 36. In a modification of this arrangement, Fig. 9 (not shown), it is the heated fluid which flows in two different directions in separate parts of the apparatus. Compression of either gas flowing through the heatexchanger may be obtained from a gas turbine actuated by the heating fluid issuing from the exchanger.

Abstract: 688,452. Television receivers. HAZELTINE CORPORATION. Aug. 3, 1951 [Aug. 14, 1950], No. 18443/51. Class 40 (iii). Relates to an intensity-modulated television cathode-ray tube display in which the sharpness of displayed intensity variations corresponding to abrupt variations of the amplitude of the video signal generated at the transmitter' is improved by generating a control signal which is a function of a derivative of the receiver output video signal and applying it to an auxiliary line deflector coil or plate to vary the line scan velocity, Figs. 1 and 1a (not shown) in the latter case the differentiating circuit may be included within the tube envelope. Owing to the limited band-width of the transmission system, the receiver output video signal corresponding to a white bar in the scene being televised, as shown in curve A, Fig. 3, and it is shown that when the control signal is proportional to the first derivative the resultant displayed brilliance variation is as shown in curve F, i.e. the edges of the bar are sharpened but the width of the bar is contracted and overshoots are present at the leading and trailing edges. The latter defect is reduced by applying a second derivative of the video signal to the grid of the tube either directly or via a clipper which passes only the negative-going portions, Figs. 7 and 8 (not shown), and in accordance with the present invention the former defect is reduced by generating a modified control signal proportional to the product of the first and second derivatives of the video signal, Figs. 4 and 5 (not shown), which produces a resultant brilliance variation F<1>, Fig. 6; if desired, the first derivative of the video signal may be combined with the modified control signal and the positive and negative portions of the first derivative applied to the product-forming circuit, e.g. balanced modulatior, may be limited by a symmetrical clipping circuit. Specification 686,327 is referred to.
