Title: Improvements in or relating to turbine plants
IPC: F02C9/18
Filed: 1947-05-23
Abstract: 623,898. Turbine plant. S U L Z E R FRERES SOC. ANON. May 23, 1947, No. 13889. Convention date, June 22, 1946. [Class 110(iii)] A turbine plant having at least two turbines arranged in series which drive independent loads, is provided with a bye-pass pipe fitted with a regulating valve leading from one turbine to an intermediate stage of the succeeding turbine in the series and an auxiliary turbine fed by the working medium passing through the bye-pass pipe and coupled to the first mentioned turbine to adjust the ratio of the turbine outputs. In the plant shown, air is compressed in the compressors 31, 32, heated in the heat exchangers 36, 37 and then passes to the point 40 where it is divided into two .parts. One part passes through the heat exchanger 52 of the heater 42 to the turbine 44 the exhaust of which returns to the inlet of the compressor 31 through the heat exchanger 36 and cooler 48. The second part is used as combustion air in the combustion chamber 50 of the heater 42. The gases leaving the heater pass through two turbines 54, 55 arranged in series. The exhaust of the turbine 55 passes through the heat exchanger 37. The turbine 54 drives a compressor 63 which supplies air to the circuit to make up for that extracted from the circuit at 40 for combustion air in the heater 42. The turbine 55 supplies the useful output. An intermediate heater 57 is arranged between the two turbines 54, 55. A motor 70 is provided for starting. To regulate the distribution of power between the turbines 54 and 55, a bye-pass pipe 8 having a regulating valve 22 and an auxiliary turbine 24 mounted on the shaft of the turbine 54 are provided. If the valve 22 is opened, the power of the turbine 54 is increased due to the decrease of back pressure and the additional power of the turbine 24 and the power of the turbine 55 decreased by the reduced amount of working fluid passing through the later stages. The bye-pipe 8 also bye-passes the intermediate heater 57. A straight through flow gas turbine plant is also described.

Abstract: 948,043. Electric capacitors. SIEMENS & HALSKE A.G. April 11, 1962 [April 12, 1959], No. 13929/62. Drawings to Specification. Heading H1M. An impregnated rolled capacitor of the selfhealing type comprises two strips of lacquered paper, or of synthetic material, on the surface of each of which a metal coating, e.g. aluminium or zinc, is deposited by vapour deposition to form a plate, a layer of lacquer being deposited upon each metal coating to seal the coating between two layers of lacquer, or a layer of lacquer and a strip of synthetic material, whereby the metal coatings are protected from decomposition products of the impregnant when dielectric failure occurs. The impregnant is a halogenated hydrocarbon, e.g. chlorinated diphenyl or chlorinated naphthalene, and is included in the capacitor between the adjacent strips of metal coated lacquered paper, or synthetic material; and one of the layers of lacquer, or the synthetic material, consists of material having an oxidation balance of at least 10% whereby during a dielectric failure the material forms stable non-conducting oxidation products which protect the layers of metal from conducting and corrosive products formed by the impregnant. When strips of synthetic material are used instead of lacquered paper the layers of metal are applied directly to the surface of the material. The oxidation balance of the lacquer applied to the paper, or that applied to the metal coatings, may be less than 10%. Examples of material having an oxidation balance of more than 10% are ethyl cellulose, benzyl cellulose, or polyethyleneterephthalate.

Title: Improvements in and connected with relay machines for organs and like musical instruments
IPC: G10B1/04
Filed: 1930-05-08
Abstract: 354,367. Organs. WALKER & SONS, Ltd., J. W., Southfield Road, Acton, London, and SYMONDSON, A. H., 69, Jersey Road, Osterley, Hounslow, Middlesex. May 8, 1930, No. 14181. [Class 88 (ii).] The playing of a manual key or pedal energizes a corresponding note-magnet whose armature causes engagement of a contact bar with those contact wires, out of a number, which have been flexed into proximity with the bar by longitudinal movement of vertical rods under the draw or like stop controls. The inertia of the parts moved by the keys is thus reduced. As shown for a pedalboard of 32 notes, the note-magnets b are arranged in four columns, eight in a column. In front of each column is a set of vertical rods n, one rod in each set for each of the (say ten) stops. Above each magnet are mounted ten contact wires g, these contact wires all projecting through apertures in the rods n. The rods n rest on arms o carried by ten rock-spindles j, the four rods corresponding to one (e.g. the Flute) stop being mounted on the same spindle. Drawing a stop collapses by electromagnetic means a pneumatic l<1> rocking the corresponding spindle j by an arm k. Thereupon the four corresponding rods n fall, flexing their springs g so that they come within the range of movement of the contact bar h carried by the tilting armature c of any note-magnet that may be energized. The rods n may be slender and obtain mutual support from the contact wires. Blade springs m adjustable at m<2> may control the stickers l of the pneumatics l<1>. The mechanism is also applicable for coupling, combination and extension work.

Title: A method and means for stimulating distillation
IPC: C10B27/06
Filed: 1925-05-29
Abstract: 234,840. Deschamps, J. J. May 30, 1924, [Convention date]. Distilling plant.-A method of distillation consists in producing pulsations in the reaction chamber by periodical injections of vapours or gases into the discharge current. The outlet pipe a of a coke-oven for example leads to a pipe b having a constriction c, into which a pipe d opens, forming an injector. A fan h supplies gas under pressure and the mechanical opening and closing of a member f causes pulsations in the gas outlet pipe and coke-oven. The addition of gas or vapour, or purified coal gas, facilitates the purification of the gas produced and removes the risk of tar being deposited in the pulsator itself. Other suitable auxiliary gases are hydrogen or water vapour. Specification 192,089, [Class 1 (i),. Chemical processes &c.], is referred to.
