Title: Improvements in or relating to the treatment of grain in silos
IPC: B65D88/74
Filed: 1950-03-14
Abstract: 673,415. Treating grain. ROESSLER, O. H.STRUB-. March 14, 1950 [March 31, 1949], No. 6404/50. Class 58 Grain is treated in silos in at least two phases during one of which air is forced through the grain by supplying the said air at a raised pressure, and during the other of which no flow of air takes place. In an example a cycle of 4 phases is worked, first fresh air is blown through for 30 minutes, second cold air flow is drawn through by suction for 30 minutes, third a period of 120-240 minutes quiet, and fourth warm air drawn through by suction for 30 minutes. The direction of flow in the second and fourth phases is opposite to that in the first and in each phase in the next cycle the direction is reversed. Before treatment an initial warm air low pressure flow may be effected to reduce varying resistance to treatment of different species of grain. The grain in a number of cells may be treated simultaneously, the cycles of treatment of the various cells being so timed with respect to each other that the air flow phases in two or more groups of cells take place during the rest phase of another group of cells, so that the cycles of treatment start successively in different groups of cells, the duration of the phase of quiet being always a whole number multiple of the duration of the air flow phases. A silo for carrying out the invention comprising 5 cells is shown in which air from the main feed duct 39 is fed to each cell via a vertical duct 24 and distributed through the cells by horizontal channels. 11 and exhausted via vertical ducts 25 into a common exhaust duct 38. Pistons 20 are so arranged that air is not distributed or withdrawn above the level of the grain. Cell III shows the arrangement for dust extraction during the filling period prior to treatment with both the vertical ducts 24, 25 working as exhausts. In the ventilation system. shewn in Fig. 18, air is blown by the fan 63 through a heater 67 into the duct 39 and thence through the silo, the exhausted air being drawn through the duct 38 by the fan 64. By moving valves 57, 58, 59, 60 in the direction of the arrow 72, the role of the ducts 39, 38 may be reversed. In a modification, Fig 19, both systems 38, 39 can be adapted for exhaust,- the heater being eliminated when the dust extraction of the cell as in cell 3 is to be effected.

Title: Improvements in the production of bodies formed of or comprising metal powder or powdered metallic compound
IPC: B22F7/06
Filed: 1943-04-22
Abstract: In the manufacture of articles from powdered material, which may be wholly or in part of metal, a number of sections are separately formed and joined to form the article required by applying to the abutting surfaces a boundary material having a lower melting point than the final sintering temperature of the body.  The parts may be formed by pressing unsintered powders or may be cut and ground from presintered bars.  The boundary material may be applied in the form of powder, foil, or by plating or sputtering &c.  Bodies of large dimensions or complicated shape may be made from carbides of tungsten, molybdenum, titanium or tantalum bonded with cobalt, nickel or iron &c., and in these cases the boundary material is the same as the bond so that the final sintering yields a substantially homogeneously bonded body. Porous bodies made from powders by sintering without bonding material are united by copper, nickel, silver, cobalt, tin, or their alloys with each other or with cadmium and zinc; the sintering material diffusing into the pores. Non-metallic powders, such as ceramics, embedded in a bond of copper &c., as above, may be united to metal parts produced as described. The sections may be arranged to have different characteristics, such as hardness, specific gravity, or brittleness.  The final sintering may take place in a mould of refractory material such as graphite.

Title: Production of combustible gases
Inventor: MCKEAN JOHN BOWIE
IPC: C10G9/00
Filed: 1954-03-08
Abstract: 762,691. Gasifying liquid hydrocarbons. SOUTH EASTERN GAS BOARD, and POWER GAS CORPORATION, Ltd. Feb. 25, 1955 [March 8, 1954; March 8, 1954], Nos. 6740/54 and 6742/54. Class 55 (2). In a cyclic process for producing a combustible gas from liquid hydrocarbons and steam the latter are mixed and then passed through a vaporizing screen 19 of hot inert material to complete the hydrocarbon vaporization before the mixture is passed through a catalyst bed 21 at a relatively high temperature. In carrying out the process according to a " run-andblow " principle during the " run," steam enters a vessel 10 through pipe 11, is superheated in a regenerator 12 of chequer brickwork, and after passing through throat 13 mixes with liquid hydrocarbons which are injected into carburetting chamber 14 through pipe 15. The mixture passes through conduit 16 into chamber 17 at the top of a second vessel 18 and mixes with more liquid hydrocarbons injected through pipe 151. The hydrocarbons are completely vaporized in the screen 19, which is a grid or chequerwork of inert refractory material, and the mixtures traverses space 20 to enter catalyst bed 21. The gases produced heat the chequer brickwork regenerator 22 before being discharged through pipe 23. The supply of hydrocarbons is cut-off at the end of each " run " period and steam continued for a short time to purge the plant of volatile substances. During the " blow '' period, air is blown into vessel 18 through pipe 24 from a blower 25 and it heats up in regenerator 22 and burns off carbonaceous deposits on catalyst bed 21, screen 19 and the walls of the plant. The hot gases flow through regenerator 12 to heat it and leave through pipe 26 for a waste heat boiler. Additional air may be introduced through pipe 27 to space 20 and also through pipes 28, 29, any or all of the air pipes being associated with burners 30, 301 or 30<SP>11</SP> in which fuel, such as the hydrocarbon used in the " run period, may be burnt. In a modification the vaporizing screen comprises a layer of inert refractory material laid on top of the catalyst bed. Specifications 648,965, 666,524 and 755,634 are referred to.

Title: Semiconductor memory system
IPC: G11B7/0045
Filed: 1973-02-12
Abstract: 1410896 Data storage INTERNATIONAL BUSINESS MACHINES CORP 12 Feb 1973 [20 April 1972] 6758/73 Heading G4C Data is stored in a layer of semiconductor material on a heat conductive substrate by heating discrete areas of the material using a pulsed laser beam to change the discrete areas from a crystalline to an amorphous state. The heat dissipation of the substrate and the duration and energy of the laser pulse are chosen not only to ensure that cooling of the heated areas is sufficiently rapid to avoid recrystallization, but also to achieve very fast write time of the order of nanoseconds. A substrate in the form of a quartz or metallized plastics disc, drum or, as shown, tape carrying the semiconductor layer, has an associated heater 32 for raising the layer to about its glass transition temperature so as to reduce the laser output power required. A bulk erasure heater 36 may also be provided. Laser 10 is pulsed to record a data bit as a change in a discrete area of the normally crystalline layer to the amorphous state. With the laser beam focused to a 1 micron spot, and the recording medium 2 transported at up to 10<SP>5</SP> cm./sec., pulsing of the laser beam every 5 n.sec. results in two micron diameter recorded spots at 5 micron centre to centre spacing. Read-out may be effected by utilizing the different absorptive or reflective properties of the two states of the semiconductor layer. As shown, with mirrors 22, 30 in position b, laser 20 provides read out to detector 18 after reflection by mirrors 22, 24, 26, focusing by lens 28 and reflection by mirror 30. Laser 20 may also be used for selective erasure by adjusting the power and duration of the pulses and the speed of the recording medium. Operation of laser 20 in the continuous wave mode would enable erasure of an entire track.  Examples of semiconductor material comprising Te, Ge and As, are given.

Title: Improvements in electric accumulators
IPC: H01M50/574
Filed: 1948-03-05
Abstract: 660,989. Batteries. BUREAU TECHNIQUE GAUTRAT. March 5, 1948 [March 14, 1947], No. 6959/48. Class 53. An accumulator is hermetically sealed, the gases evolved during the charging process being recombined catalytically either by the material of the plates or by a catalytic agent such as spongy platinum. At the conclusion of the charging process the increase in the gas pressure is used to cut off the charging current by means of a movable diaphragm in the accumulator acting on a switch. Fig. 1 shows a single cell consisting of an iron container 1 closed at the bottom by a rigid plate 2 and at the top by a flexible diaphragm 3 carrying a stud 10 which passes through an opening in a metal plate 7 in contact with the container 1 and forming one of the terminals. In contact with the container are two anodes 4 consisting of nickel oxide enclosed in perforated nickel boxes, and between the anodes is an iron or cadmium cathode 5 having a terminal 6 passing through the container bottom. The container is partly filled with a solution of caustic potash. The charging current is led into the cell through a spring 8 which rests on the plate 7 and stud 10. Evolution of gas when the cell is fully charged lifts the diaphragm 3 and opens the contact between the plate 7 and spring 8. Separate charging and discharging circuits are provided as shown in Fig. 7, the two circuits having a common negative terminal 11 but separate positive terminals 13, 14. In order to safeguard the battery in the event of the discharging circuit 14 being used for charging purposes the diaphragm 3 may be provided with a second stud similar to the stud 10 but of shorter length and acting on a second spring in the discharging circuit. If this circuit is used for charging the accumulator the current is interrupted by the second stud when the gas pressure rises sufficiently at the end of the charging operation. Fig. 4 shows a modification of the accumulator comprising a metal cup 15 containing nickel oxide 17 covered by a perforated plate 18 of nickel or nickel plated iron which supports blotting paper 25 impregnated with caustic potash solution. Resting on the paper 25 is an iron cup 23 having a perforated bottom and an iron closing plate 22 and which is insulated from the cup 15 by a ring 19. The cup 23 contains iron or cadmium powder 21. A plate 20 closes the cell and bends upwards under gas pressure to interrupt the charging current. A number of cells may be joined in series by being stacked one upon another.
