Patent GB-385032-A (GB)
Title: Improvements in and relating to cementitious material of the high alumina type
IPC: C04B7/32
Filed: 1931-09-14
Abstract: Products containing calcium aluminate and obtained by treatment of highly aluminous material with lime are subjected to the action of carbon dioxide to carbonate the free lime and loosely combined lime. The resulting cement resembles ordinary aluminous cement in hardening properties but is more plastic.  The treatment with carbon dioxide may be effected by passing the material through an inclined rotating cylinder through which furnace gases at 500-700 DEG  C. pass in counter-current.  The treatment is particularly applicable to products obtained by treating alumina and lime with steam, e.g. at 200 lb. pressure for about three hours.  It is also applicable to the products obtained by first treating the raw materials with steam and then heating to about 1000 DEG  C. as described in Specification 303,639, [Class 22, Cements &c.], or to products obtained by the action of heat without steam treatment.

Title: Improvements in supplementary liquid fuel tanks of the vacuum gravity type
IPC: F02M37/02
Filed: 1919-10-22
Abstract: 155,082. Paterson, T. W. Oct. 22, 1919. Vacuum apparatus.-A vacuum fuel-feed apparatus comprises an outer fixed container 1 open to the atmosphere, a fixed intermediate container 2 connected by a pipe 15 to suction, and an inner movable container 3, balanced by the weights 8 and provided with a valve 10, the stem 11 of which carries a valve controlling the admission of fuel to the container 2. When the fuel rises. in the container 2 and overflows into the container 3, the latter falls and opens the atmospheric valve 7, so as to break the vacuum, and at the same time opens the valve 10 and a diskvalve 6, and closes the inlet valve 11. The fuel then flows into the container 1, which is connected to the carburettor. When the containers 2, 3 are empty, the latter rises, thereby closing the valves 6, 7, 10, and opening the valve 11, and the cycle is repeated. The valve 6 carries a tube 13 which is depressed when the container 3 falls. A stand-pipe 18 may be mounted on the delivery pipe 17 to indicate the rate of feed. A valve under the pressure of the lubricating system, as described in Specification 142,049, [Class 122 (iv), Steam-engines, Regulating &c.], may be arranged in the pipe 15, so that, if the lubricating system fails, the valve cuts off the suction and the fuel supply to the engine stops.

Title: Improvements in or relating to pressure-governing apparatus for hydraulic circuits
IPC: F15B1/027
Filed: 1952-10-15
Abstract: 721,645. Fluid-pressure servomotor control systems. SOC. D'INVENTIONS AERONAUTIQUES ET MECANIQUES S.I.A.M. Oct. 15, 1952 [Oct. 15, 1951], No. 25896/52. Class 135. In a pressure-regulating valve for a hydraulic system supplied with pressure fluid by a pump 2 and of the type in which a pump unloading valve A is actuated by a piston Y under the control of a spring-loaded pilot valve B, and in which the two sides of the piston are interconnected by a restricted passage A<SP>2</SP> and the pilot valve, subject to the pressure in the chamber a at the back of the piston, opens towards the exhaust connection on a predetermined pump output pressure being attained and so exhausts the chamber a, a movable member P responsive to the pressure in the hydraulic system (e.g. in accumulator 4) serves, after the pilot valve has opened, to hold, or assist in holding, the pilot valve open until the system pressure falls below a predetermined value. The pump 2 receives liquid from a tank 1 and supplies it under pressure past a non- return valve 3 to the accumulator 4 and a hydraulic circuit 5. When pressure is released in the chamber a due to the opening of pilot valve B, the pump outlet pressure acting on the front face of piston Y forces the latter to the left and so opens the valve A which by-passes the pump outlet to tank 1 through conduit h. An intermediate annular chamber d communicates with passage A through a restriction f and so acts as a dashpot to prevent sudden movements of valve A.

Abstract: 242,071. White, S. D., and Kramer, J. B. Oct. 30, 1924. Magnetic separators.-In a magnetic separator for extracting magnetic material from fluid material such as clay slip, of the kind in which the separation is effected by two sets of combs or finger-like projections connected to the poles of an electromagnet, the combs 1, 2, having flat teeth of angular or L-shape are pivotally mounted at 3, 4 on the casing a containing the electromagnet and are connected to the poles of the latter. The combs 1, 2 are moved to produce, in the working position as shown in Fig. 2, a tapered or V-shaped space between their adjacent edges, the width of the space being proportional to the taper of the teeth so as to produce a uniform field between the latter, or separated, as in Fig. 1, for the purposes of cleaning the teeth. The combs 1, 2 are also arranged so that the respective teeth are in staggered relation to each other. To stop the supply of clap slip if the current fails, a part of the trough along which the slip is fed is separately mounted and is held in the closed position by a solenoid or another electromagnet, and when the current fails this part of the trough drops, the slip being delivered into a receptacle and not passed on to the combs 1, 2. A visual or aural signal may also be operated at the same time.

Title: Improvements relating to the manufacture of cement by the wet process
IPC: F27B7/20
Filed: 1932-09-24
Abstract: 407,941. Rotary cement kilns. NIELSEN, N., 44, Fuglebakkevej, Frederiksberg, near Copenhagen. Sept. 24, 1932, No. 26584. [Class 51 (ii).] Preheating charges.-In the manufacture of cement by the wet process, the raw slurry material is, without being nodulized, formed into a coherent layer on a gas permeable bed. For this purpose it is subjected to a preliminary heating process sufficient to cause it to become porous as a result of the formation of cracks and pores. Hot gases are then passed through the layer which is thereafter fed, without further grinding, into a kiln. A mechanical device, such as a spiked roller may be used to assist the formation of pores and cracks. When the slurry is applied to the bed in liquid form the preliminary heating may be effected by passing hot gases upwards through the bed so that they bubble through the layer of slurry. Alternatively the hot gases may be led along the surface of the slurry while the openings in the bed are kept shut by dampers or the like. In this case the slurry may be partially dewatered, or stiffened by the addition of dry material. The gas permeable bed is preferably movable and may consist of a chain grate, a rotating perforated table or cylinder of metal which may be a heat resisting alloy or covered with perforated refractory material. The hot gases are arranged to pass first through the material and then through the bed so that the bed is not exposed to extremely hot gases. The same hot gases can be used subsequently for the preliminary drying. In the arrangement shown, a kiln smoke chamber 2 at the inlet end of a rotary kiln 1 contains a grate formed by an endless band 3 having hinged flaps 9 adapted to swing into the vertical position when they reach their lower position. The smoke chamber above the grate is divided into two chambers 5, 6 in the first of which the slurry material on the grate is dried and in second 6 of which the material is subsequently further heated.
