Title: Improvements in or relating to a method and an equipment for the drying of granular and powdery materials
IPC: F26B17/16
Filed: 1950-05-11
Abstract: 672,079. Drying granular material. GOULOUNES, N., and CAILLAT, A. E. May 8, 1950, [May 23, 1949; April 24, 1950], No. 11427/50. Class 34(ii) In a method of drying granular materials such as ores, the material is heated in an intermediate zone 3 of a vertical column which communicates with the atmosphere and through which the materials flow by gravity, by means of heating tubes 13 through which circulates steam at a temperature above 100‹C. and at a pressure slightly above atmospheric pressure, and the vapour extracted from the materials to be dried is returned through a compressor 21 to be used in heating the said pipes. In addition condensation water from the heating tubes 13 circulates through members 37 in an upper part 2 of the column to preheat the incoming material and some of the dried material is mixed with incoming wet material to reduce the average water content when the incoming material has a very high water content. The apparatus has a loading hopper 1 with bars 45 to break the fall of the material, a preheating section 2, a drying section 3, a superheater 4 with heating by steam at still higher temperature, a steam joint 5 with an inlet of air at high pressure to force back steam which might otherwise be drawn down with the falling material, a cooling section 6 with pipes 44 through which flow cold water and a discharger 7 from where the materials fall through adjustable openings 8 in a bottom plate 9. The evaporated moisture from the drying section is collected in a header 17 through perforated pipes 18 and passes through a duct 19 into a dust-remover 20 and thence into the compressor 21 which forces it into duct 11 and pipes 13. The uncondensed steam goes through a pressure reducer 22 and part is discharged into the atmosphere at 23 the remainder being returned to the compressor 21. This compressor is driven by a steam turbine 24 fed through a duct 25, the exhaust being fed to duct 11 through a pipe 26. The superheater 4 has pipes 27, 28 fed with steam through duct 29 and discharged at 30, the incondensed steam passing into a pressure reducer 31 and then into the duct 11. The condensate from the drying section 3 is collected through a duct 32 and that of the superheater through a duct 33, pumps 34, 35 forcing it into the pipes of the preheating column 2. Cold water from this preheater feeds the cooling section 6 through pipe 41 and pump 43, some water being discharged at 42. A modification has an extra preheater fed by steam from an outside source but no superheater 4.

Title: Improvements in apparatus for forcing liquids by vapour pressure
IPC: F04B9/10
Filed: 1953-04-27
Abstract: 726,011. Forcing liquids by vapour pressure. AKTIEBOLAGET ZANDER & INGESTROM. April 27, 1953 [May 7, 1952], No. 11643/53. Class 102 (2). Apparatus for forcing liquids comprises a chamber 1 for the liquid supplied through pipe 10 and delivering through pipe 10a fitted with non-return valves 20, 21 respectively. Electrodes 2 immersed in the liquid generate vapour pressure to eject the liquid and subsequently coolant is passed through the condenser 11 to condense the vapour and draw in a further charge of liquid. The supply of coolant is controlled by an electromagneticallyactuated valve 12 controlled by electrodes 6a, 6b through a switch actuated by a solenoid 25 so that the valve 12 is opened when the liquid reaches the lower level and closed when it reaches the higher level. The discharge of the condenser may be used to heat the liquid in a tank 16. In a modified form, the electrode vapour generator may be separate from the liquid forcing chamber and may be situated within it and heat insulated from it, or may be outside and connected by piping.

Title: Improvements in or relating to electric control apparatus for regulating the load distribution of dynamo electric machines
IPC: H02P5/68
Filed: 1934-04-18
Abstract: 434,368. Automatic regulation. IGRANIC ELECTRIC CO., Ltd., 147, Queen Victoria Street, London.-(Assignees of Stansbury, C. ; 12th Avenue, Milwaukee, Wisconsin, U.S.A.) April 18, 1934, No. 11672. Convention date, April 20, 1933. [Class 38 (iv)] [See also Group XXXVII] Comprises an arrangement for maintaining a predetermined division of load between dynamoelectric machines. Fig. 1 shows an arrangement in which the ratio of loads carried by two motors 1, 2 is maintained constant. The motors are connected to the D.C. supply 7, 8 in series with saturating windings 9, 10, of chokes 11, 12, the windings 26, 27 of which are connected in series with resistances 28, 29 respectively to an A.C. supply 30, 31. The load ratio is maintained by means of a field rheostat 15 associated with the motor 2, this being adjusted by a reversible motor 17 under the control of a relay 20 which responds to the unbalance of the bridge formed by the resistance 28, 29 and chokes 26, 27. In a modification of this the motor 2 is provided with an auxiliary field winding which is supplied from the A.C. supply through a grid controlled valve, the grid potential of which is varied to maintain balance by means of a further valve, the anode of which is connected to the resistance 29 and the grid through a transformer to the resistance 28. Variation of the load ratio causes a variation of the phase relation between the grid and anode potentials. Fig. 5 shows an arrangement for the control of a number of motors. Here the grid potential of the valve controlling the supply to the auxiliary field winding 6a is obtained from across condensers 54, 55 and a resistance 59 connected in series. The condensers 54, 55 are charged to potentials proportional to the potentials across the resistances 29, 28 by means of a double anode valve 58. When the load ratio is correct the potentials across these condensers cancel, but any variation of the load ratio causes a difference potential across these condensers which alters the grid control of the valve 50 supplying the auxiliary field winding. The motor 102 is controlled with reference to motor 1 in a similar way. A switch 130 is provided to enable motor 2 to be used as the leading- machine.

Title: Improvements in or relating to direction finding systems for use in connection with aircraft
IPC: G01S1/02
Filed: 1932-04-23
Abstract: 400,276. Directive wireless signalling. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, and LINSELL, A. A., 43, West Hill, Sydenham, both in London. April 23, 1932, No. 11734. [Class 40 (v).] To facilitate accurate D.F analysis at a land station of signals transmitted from an aircraft, reflection from the Heaviside layer is eliminated by suppressing as far as.possible any upward component of radiation when the craft is flying on an even keel. The desired type of radiation is secured by using a frame and openaerial combination, giving the usual cardioid characteristic with the maximum spread pointing downwards. Two such systems may be combined at right-angles. Another arrangement comprises two dipoles 1, 2, Fig. 2, arranged at 45‹ to the vertical and backed by reflectors 3, 4, with or without a third horizontal set 5, 6, the whole being duplicated if necessary, or a single vertical dipole 8, Fig. 3, may be mounted on gimbal-bearings so as to keep its vertical orientation for all positions of the craft. Preferably any aerial system which is fixed relatively to the craft is energized, through a pendulum switch, only during such times as the craft is flying on a level keel. Suitable compensating means are utilized to prevent distortion of the field due to re-radiation from nearby conductors, such as bracing-wires &c. At the land station the signals are received (a) on a Bellini-Tosi aerial at long range, or on an Adcock aerial at comparatively close range ; or (b) on a universally-mounted frame aerial ; or (c) on a pair of dipoles which can be tilted in the vertical plane. Specification 397,524 is referred to.

Title: Improvements in or relating to the manufacture of rubber products
IPC: C08L7/00
Filed: 1932-04-29
Abstract: Plantation rubber is treated with oils, greases, waxes, resins, soaps and the like, and other ingredients are added to it, to bring it to a condition of softness and plasticity similar to that of reclaim, to enable it to be used as a substitute therefor. According to an example, 1 part of linseed oil is emulsified in 2 parts of a 5 per cent potash solution.  11 1/4 lbs. of this p  emulsion are added to 100 lbs. of latex with agitation, and the solids are coagulated, washed, and cr<\>zeped as usual.  Ten per cent of carbon black is gradually incorporated on the rolls to give a substitute for black reclaim, and confers similar qualities to a rubber mix.  White and red reclaims may be imitated by the addition of zinc white, and iron oxide, respectively.  In modifications, the oil &c. may be added to the latex without previous emulsification, and the other ingredients may be added prior to coagulation of the latex.  Examples are given showing the effect of the usual tests on mixes containing reclaim and the new product.
