Abstract: 533,654. Delivering measured quantities of powdered &c. material. JACKSON & CROCKATT. Ltd., J. G., and GAIR, D. Aug. 31, 1939, No. 24949. [Class 106 (v)] A closure element 5 carried by a rotating shaft 4 allows powdered or granular material in a container 1 to pass at intervals into a measuring chamber 3 from which it is discharged into a funnel 33, when a cam on the shaft 4 allows two shutters 8 beneath the measuring chamber to be opened by springs 10. The shutters 8 are connected by a link 9 so as to open or close simultaneously and one shutter is held by springs in engagement with a resiliently mounted plunger 12 on a lever 11 which also carries a roller 13 engaging the cam 14. A cam on the shaft 4 operates an arm to uncover an air inlet 3c in the measuring chamber during discharge. The plunger 12 is attached to the arm 11 by a pivoted block 12a which can be turned to allow the shutters to open for cleaning. The shutters carry rollers 15 engaging an adjustable inclined track 16 below the measuring chamber to wedge them into engagement with the lower part 3b of the measuring chamber. The lower part 3b is adjustable by a screw 18 on the frame of the apparatus to vary the capacity of the measuring chamber. The shaft 4 is rotated by a constant speed electric motor 20 through variable speed belt gearing 22 and worm reduction gear 21, the gear 21 being arranged in an annular oil trough 24. On removing a nut 25 securing the wormwheel the shaft 4 may be lifted out of the container 1. The material delivered from a hopper 2 into the container 1 may be regulated by a screw-and-nut mounting 26. A trip mechanism may be provided by which a lever 27 preventing the shutters 8 from opening by engagement with the block 12a is removed when a receptacle is placed below the funnel 33 by displacement of a feeler arm 28 on a spindle 29 carrying a hooker arm 31 engaging a rod 32 depending from the lever 27.

Title: Improvements in or relating to a gas turbine plant
IPC: F02C6/18
Filed: 1966-06-03
Abstract: 1,138,165. Gas turbine plant - fuel supply. M.A.N. TURBO, G.m.b.H. June 3, 1966 [June 9, 1965], No.24954/66. Heading F1G. The invention relates to a gas turbine plant in which liquid or gaseous fuel is passed together with water into a reaction chamber being heated by passing the turbine exhaust gases in heat exchange therewith, whereby an endothermic reaction takes place in the chamber, the reaction products being a mixture of carbon monoxide and hydrogen which is then utilized as fuel in the combustion chamber. A feature of the invention is the provision of a further reaction chamber in which the endothermic reaction is completed, this chamber being heated by working fluid tapped from an intermediate point of the turbine. The gas turbine plant shown comprises an air compressor 23, an air preheater 22, combustion chamber 10, a first, high pressure turbine 12 which drives the compressor, and a second, low pressure turbine 14 which provides useful power. The exhaust gases from the turbine 14 pass through duct 16 to the reaction chamber 9, the exhaust gases then passing through line 21 te the air preheater 22 and thence to atmosphere. A mixture of hydrocarbon fuel and water is passed from tank 1 by pump 8 to the reaction chamber 9 which contains a suitable catalyst and is heated by the turbine exhaust gases, the resulting endothermic reaction producing a mixture of hydrogen and carbon monoxide. The reaction is not completed in the chamber 9 because the temperature is not sufficiently high, so the reaction products are passed to a second chamber 48 which is heated by working fluid tapped from the turbine 12 through line 29 and returned thereto through line 30. The endothermic reaction is thus completed and hydrogen and carbon-monoxide fuel mixture is passed to the combustion chamber 10 to be combusted therein. A valve 17 is provided in the line 16 to control flow of turbine exhaust gases to the reaction chamber 9 in dependence on temperature of the discharging reaction products or temperature of the chamber. The valve 17 may also be moved to close off gas flow to the chamber 9, the gas flow then passing through line 20 to line 21. The plant may be operated on normal liquid or gaseous fuel from tank 5 during starting, the valve 26 being operated so that fuel passes through line 27 direct to the combustion chamber. Alternatively, the reaction products discharging from the chamber 9 may be passed through hollow stator blades of the turbine to be further heated, the final products then passing to the combustion chamber 10.

Title: Process for crystallizing resinous polyesters
IPC: C08J3/12
Filed: 1951-10-30
Abstract: Amorphous crystallizable water insoluble linear polyesters are converted to a granular crystalline state by kneading in the presence of water at a temperature below, but not more than 30 DEG C. below, the melting point of the crystalline form.  The water aids the kneading process and assists in removing the heat of crystallization. The water may be added incrementally or continuously and is preferably kept to a minimum.  In an example 80 lb. of poly-ethylene fumarate of acid number 28 was transferred from the reaction vessel at 150 DEG C. to a double arm sigma blade kneading machine.  Water was added, while kneading, in four increments of 8 to 16 ozs. to reduce the temperature to the crystallizing range.  After 10 minutes and at 85 DEG C. crystallization commenced and to maintain kneadability further increments of water were added to a total quantity of 10 lb. in 12 increments over a period of twelve minutes after which the mass disintegrated to a granular mass of crystal agglomerates.  The temperature during crystallization remained about 88 DEG C.  The granular mass was hard and friable and melted at 97 DEG C. and could be readily ground in a hammer mill.ALSO:Amorphous crystallizable water-insoluble linear polyesters are converted to a granular crystalline state by kneading in the presence of water at a temperature below but not more than 30 DEG C. below the melting point of the crystalline form.

Title: Improvement in variable electric condensers
Filed: 1924-10-27
Abstract: 246,558. Dubilier Condenser Co. (1921), Ltd., (Nyman, A.). Oct. 27, 1924. Condensers of the variable type have the capacity changes effected by causing or permitting an electrically conductive fluid to come into proximity with a greater or less number of a series of fixed elements of an electrically conductive material. The insulating plates 1 carry conducting strips 2 co-operating with movable elements m in the form of mercury adapted to fill more or less of the guideways 4 and so vary the capacity. These guideways are located in casings 3 formed of a base 15 and cover 19 so as to leave vertical ducts 21 communicating by means of pipes 5, 11 with a pump 7 comprising chambers 8, 9 and a partition 10. The casings 3 are spaced apart with as many of the plates 1 as is necessary placed between, each plate constituting a unit and the units constituting a section with the corresponding strips 2 of each section connected in series. A terminal block 12 connects each section to one pole of the circuit while the other pole is connected to the conduit 5. Cap plates 22 leading to couplings 23 connect the pipes 5, 11 with the guideways 21. The pump 7 may have a reciprocable piston or be formed as a bellows, and in the latter case the walls of the chambers 8, 9 are fluted to allow each chamber to expand or contract. The chamber 8 and pipe 5 are full of mercury, which also fills some or all of the ducts 4, depending on the position of the partition 10 and consequently the capacity in use, the capacity being varied by raising or lowering the' partition by means of the hand-wheel 31. The rest of the ducts 4, the pipe 11, and chamber 9 are filled with an insulator such as oil which rests on the surface of the mercury in the casings 3.
