Title: Regenerative air preheater having a stationary heat retaining mass and rotatable fluid inlet and outlet connections
Inventor: KOCH JAKOB
IPC: F28D17/04
Filed: 1962-08-31
Abstract: 1,022,356. Thermal regenerators. SVENSKA ROTOR MASKINER A.B. Aug. 31, 1962, No. 33473/62. Heading F4K. The stationary matrix of a rotary-duct type thermal regenerator is arranged in stages between which is a slide valve 8 which rotates synchronously with the ducts 6<SP>1</SP>, 611. The valve moves in a space 3 between the stages and separates the heat exchange fluids (e.g. air and flue gases). The space 3 permits the addition or withdrawal of one or other of the fluids between the stages, and also enables by-passing of one or other of the stages by a part of either fluid. As shown, part of the flue gas stream 5 by-passes stage 1 and is diverted through a feed-water heater or evaporator 16. In other forms described each matrix stage is annular in which case the gas stream which by-passes stage 1 may pass to stage 2 by way of the cylindrical bore of the annulus Fig. 7, (not shown). This bore may contain the heat exchanger 16 Fig. 5, (not shown). Figs. 8 and 10 (not shown) depict arrangements also employing annular matrix stages. In Fig. 8, all the air passes through stage 2 and then part of the air is by-passed through the bore 100 of stage 1 to a separate duct 24, the remaining air passing through stage 1 to an outlet duct 4<SP>11</SP>. In Fig. 10 part of the incoming air is by-passed through the bore of stage 2 to the space 3 between stages, all the air then passing through stage 1. The heat exchanging fluids may pass through the matrix in concurrent or, as shown, in opposite directions.

Patent GB-836130-A (GB)
Title: Improvements relating to the control of electric traction motors
IPC: B60L9/26
Filed: 1956-11-02
Abstract: 836,130. Control of motors. SOC. GENERALE DE CONSTRUCTIONS ELECTRIQUES ET MECANIQUES ALSTHOM. Nov. 2, 1956 [Nov. 4, 1955], No. 33514/56. Class 38 (3). In a traction system, the armature of each motor is shunted during the early stages of the starting operation in order to reduce the tendency towards wheel slippage. As shown, on the first notch of a master controller, contacts 11, 18, 18<SP>1</SP> are closed together with the resistance contacts 17, 17<SP>1</SP> so that the line current initially passes through all the sections of resistor 3 except the last which is shunted across the armature 6 of a first series motor. The current then passes through the contact 11 to a second motor which is connected in a manner similar to the first. The series resistor 3 is then progressively reduced to a predetermined value, the armature shunting resistance remaining unchanged. Thereupon the shunt resistance is increased, and this operation is followed by the opening of contacts 18, 18<SP>1</SP> to interrupt the shunt circuit before all the series resistance has been removed. Transition from series to parallel connection of the motors is effected by the shortcircuit method, and, after the motors have been connected in parallel, either the shunt resistors may be restored or the shunting of the motors dispensed with. In another arrangement, the vehicle is provided with motors connected in series pairs, each motor of a pair being preferably provided with an individual shunting resistance. This reduces the tendency to wheel-slip especially if the motors are supplied from a generator having a voltage-characteristic of decreasing slope, Fig. 5 (not shown). The motors may be of the direct-current or single-phase types. In the latter case each entire motor (including its field winding) is shunted by the resistance. Specifications 347,656 and 724,412 are referred to.

Title: Improvements in Fluid Control System of Liquid Storage Apparatus.
IPC: F17C13/12
Filed: 1968-07-16
Abstract: 1,196,065. Liquefied gas storage containers. VEHOC CORP. 16 July, 1968 [21 Aug., 1967], No. 33840/68. Heading F4P. L.N.G. is stored under pressure and near its boiling point in a heat-insulated vessel 20a having no ullage space and vapour evolved due to heat leak together with expanded liquid is vented through a duct 34 leading to a drum 38 of sufficient capacity to accommodate said vented vapour and liquid and having sufficient ullage space to provide for expansion and vaporization due to normal heat leak in the drum itself which latter has a pressure relief vent valve 61 in a discharge stack 62. A plurality of vessels 20a to 20n are vertically mounted in a ship's hold and have access ducts 21a to 21n connected by relief valve 36a to 36n to the vent duct 34 and by liquid block valves 27a to 27n to an insulated liquid header 26 having one end leading to the drum 38 and the opposite end connectable to a shore liquidfill and emptying line 11 and a pump 12 to a tank 10. The storage vessels have further access ducts 22a connected by relief valves 35a to 35n to vent duct 34 and by block valves 31a to a main uninsulated vapour header 30 connected at one end to drum 38 and connectable at the other end to a shore line 13 and a compressor 14 to the vapour space of tank 10. Vapour block valves 31a-31n are each controlled by a liquid sensor 32a to 32n whilst the liquid block valves 27a to 27n are controlled by vapour sensors 28a to 28n. The liquid level in drum 38 is maintained below a predetermined height by means 49 which withdraws excess liquid, vaporizes it and discharges either through valve 61 and stack 62 or through a line 55 to the ship's engines or to a burner 59. To fill the vessels 20a-20n and with shore lines 11, 13 connected to headers 26, 30 a valve 48 in header 26 is closed, valves 23a to 23n and open as are valves 15, 16, 29, 33 and pump 12 is operated and liquid flows through open liquid block valves 27a to 27n to the vessels 20a to 20n whilst vapour is forced through open valves 31a to 31n, header 30 and line 13 to tank 10. When a given vessel, say 20a, is filled with liquid, the level reaches a sensor 32a which then closes the liquid block valve 27a, which it controls, and filling is completed when sensor 32n closes valve 27n. During the voyage valves 23a to 23n and 27a to 27n are closed but valve 48 and vapour block valves 31a to 31n remain open whereby expansion liquid in access ducts 22a to 22n gains access to the uninsulated header 30 where it is vaporized and carried through the vent header to the drum 38.

Abstract: 920,628. Semi-conductor devices. SHOCKLEY TRANSISTOR CORPORATION. Oct. 13, 1959 [Nov. 21, 1958], No. 34675/59. Class 37. A semi-conductor switching array comprising a plurality of switching devices is produced by providing a plurality of parallel ohmic contacts on each surface of a slice of semi-conductor material having the desired layer structure for the switching device, and removing the material from between the contacts to form a device at each cross-over point. Figs. 1 and 3 show such an array having 10 conductors in each of the groups 12 and 13 with a four-layer switching device 14 at each cross-point. The arrangement is produced by applying the parallel conductors to a slice of semi-conductor material of the desired structure and then etching away the unwanted material to leave separate switching devices at each cross-point. The conductors may consist of molybdenum or tungsten, if desired gold-plated, which resists an etchant such as a mixture of hydrofluoric and nitric acids. The semi-conductor structure may be of the type described in Specification 814,913 in which a PNPN layer device is produced by diffusion through spaces in an oxide layer on the semi-conductor, to provide highly doped inner regions which provide the breakdown characteristic, surrounded by regions of lower conductivity which provide the holding current characteristic; etching is carried out so as to leave a device comprising these inner and surrounding regions at each cross-over point. The parallel conductors may be applied simultaneously as fingers projecting from a common section which is later removed to provide the separate conductor elements. The top and/or bottom layers of the PNPN structure may be left on the conductors interconnecting the devices, provided all three PN junctions are exposed. The assembly may be housed in a sealed ceramic case. Additional conductors may be provided so that faulty switching devices can be excluded from the array.
