Patent GB-581012-A (GB)
Abstract: 581,012. Closed solid-fuel stoves. MARTIN, P. S. Feb: 3, 1944, No. 2005. [Class 126] In a closed stove having a coking chamber 14, which serves as a fuel magazine, arranged above the fire chamber 10, primary air passes to the grate 4 through an inlet 7 controlled by a damper 8, while secondary air is supplied through apertures 40 in a manifold 28 to the lower part of an annular gas combustion chamber 22 which surrounds the magazine and into the lower end of which the gases from both the fire chamber and the magazine pass. The gas inlets to the combustion chamber 22 are constituted by ports 12 formed by upwardly and outwardly diverging portions of the bricks 11 lining the fire chamber. The secondary air is supplied to the manifold 28 through an opening 32 from a chamber 33 which houses a thermostat 34 connected to a damper 35 controlling an inlet in the lower end of the chamber; the thermostat may also operate the primary air damper 8. The combustion chamber is fitted with vertical baffles which progressively decrease in height the nearer they are to the gas escape outlet 20 and a curved deflector is provided below the outlet 20 to prevent the gases ascending at that side of the stove from passing straight through the outlet to the chimney connection 25. The latter is attached to a cover 23 fitted with a hinged stoking door 24 which is interconnected with a damper 27 so that the latter is automatically opened during stoking to provide a direct draft through the fuel door opening and thus prevent escape of gases into the room. To prevent bridging of the fuel'in the magazine, the lining bricks 16 are vertically corrugated and a small quantity of air is led from the ashpit 5, through a vertical pipe 13, Fig. 7, traversing the combustion chamber 22, to the upper end of the magazine, this air passing downwardly along the corrugations to effect combustion at the periphery of the fuel column and ensure a smooth and even descent into the fire chamber.

Abstract: 1334365 Preparing alkane phosphonic acid diesters FARBWERKE HOECHST AG 14 Dec 1970 [16 Dec 1969 2 Sept 1970] 59307/70 Heading C2P An alkane phosphonic acid diester of the general formula in which R 1  is C 2 -C 22  alkyl and R 2  and R 3  are C 1 -C 22  alkyl is obtained by reacting a dialkyl phosphite HPO(O)(OR 2 )(OR 3 ) with an α- monoalkene of 2 to 22 carbon atoms and containing less than 0À002% by weight of sulphur in the presence of a free-radical generator at 130-250‹ C. The olefin and dialkylphosphite are preferably used in substantially equimolar proportions although an excess of either may be used. The process may be carried out in an inert gas atmosphere and in the presence of an inert solvent, e.g. an alcohol, ester or hydrocarbon but it is generally preferred to work in the absence of a solvent. Specified free radical generators are organic peroxides and/or ultraviolet light. Small amounts of the corresponding phosphonic acid and its monoester are also formed and the crude diester product may be purified by distillation or may be hydrolysed directly to form the phosphonic acid or treated with PCl 5  or phosgene to form the phosphonic acid chloride or ester chloride. The main process can be carried out continuously.

Abstract: 650,179. Control of A.C. motors; controllers; retractive switches. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. April 20, 1948, No. 10858. Convention date, May 10, 1947. [Classes 38(iii) and 38 (v) '[Also in Group XX] Photofluoroscopic apparatus comprises an X-ray tube carriage and a photofluroscopic carriage which are slidably supported on columns extending from base members, and connected for movement in the same direction, a chain depending from the top of one column, and an electric motor driving a sprocket engaging the chain to move the carriages, the motor be-. ing driven in either direction by a handoperated switch. The switch, Fig. 5, comprises three insulated contact-bearing discs on a shaft 56. A pinion 55 on shaft 56 meshes with teeth 54 on a sector-shaped arm of a pivoted lever 53. The other arm of the lever is extended outside the apparatus housing by a lever 52. Springs 57, 58 bias the switch to its inoperative position, Fig. 7, wherein brushes 76, 80, 85, 79, 77, 86 bear on insulating parts of the discs 59, 60, 62. Each disc has four contacts at cardinal points on the edge. The four contacts on disc 62 are inter-connected, and when the shaft 56 is turned in either direction, connect brushes 77, 86 to complete the circuit from supply lines L 1 , L, to the main winding 78 of the motor, which is an A.C. induction motor. Opposite contacts 63, 66 and 67, 70 on discs 59, 60 respectively are connected, and contacts 64, 65 on disc 59 are respectively connected to contacts 68, 69 on disc 60. Rotation of shaft 56 in one direction connects lines L 1 , L 2  through condenser 82 and switch 83 to the motor starting winding 84, while rotation of the shaft in the other direction connects the lines to  the winding 84 similarly but in opposite phase. Switch 83 opens when the motor starts to run. The arrangement is such that when lever 52 is depressed the carriages move downwardly and when the lever is raised the carriages move upwardly. Overrunning of the carriages is prevented by mounting stop pins on the column carrying the carriage on which the switch is mounted which engage and push into neutral position the lever 52 when the carriage approaches the limit of its travel in either direction.

Title: Method of Manufacturing an Electrophotographic Recording Material, Suitable, for Example for Medical X-Ray Radiography
IPC: G03G5/147
Filed: 1979-02-16
Abstract: A problem in making electrophotographic materials having a dielectric foil bonded to a porous photoconductive layer is the reduction in sensitivity caused by the bonding process used. An electrophotographic recording material comprises an electrically conductive substrate bearing a porous photoconductive layer consisting of photoconductor particles dispersed in a binder and a dielectric foil being bonded to the photoconductive layer. A layer of a dispersion of the photoconductor particles in a solution of the binder in an organic solvent is provided on the substrate, and this layer is partly dried. The dielectric foil is applied to the partly dried layer, and is pressed towards the substrate while the photoconductive layer is still moist. Pressure on the dielectric foil is released before the photoconductive layer has dried completely. The binder content of the porous photoconductive layer is between 0.1 and 5% by weight.
