Title: Improvements in and relating to electric control systems for arcing electrodes
IPC: H05B7/152
Filed: 1922-05-17
Abstract: 202,063. British Thomson-Houston Co., Ltd., (General Electric Co.). May 17, 1922. Regulating, automatic systems and apparatus for.-An electric control system for arcing electrodes includes an electric valve connected so as to be responsive to the electrical condition of the arc, and electroresponsive means, controlled in part by the valve, for regulating the arcing relation of the electrodes. An electric furnace 13 is provided with electrodes 10, 11, 12 supplied with current from the secondary of a transformer 32, the primary of which is supplied with current by leads 31. The electrodes are operated by motors 14, 15, 16 having separately-excited field windings and supplied with current by generators 27, 28, 29 driven by a motor 30 energized from the leads 31. Each generator has a pair of differentially-wound and separately-excited fields 35, 34. The field 35 is supplied with current from an exciter 33, and the field 34 comprises part of a circuit which includes an electron discharge valve 17 and the secondary of a transformer 23. The primary of the transformer 23 is formed in each case by a coil in the lead supplying current to one of the electrodes. The valve 17 comprises a plate 21 and a hot cathode 20 connected across a portion of the secondary winding of the transformer 23, and including an adjustable resistance 26 in the circuit. These resistances 26 are adjusted so that, with normal arcing relationship of the electrodes, the plate current of the valve is such that the fields produced by the windings 34, 35 neutralize one another. An increase in the current supplied to the electrode 10 produces a corresponding increase in the voltage of the secondary of the. transformer 23. The heating effect of the cathodes 20 is thus increased with a consequent increase in the current in the plate 27 and the winding 34. The balance between the fields produced by the windings 34, 35 is thus destroyed, and the generator 27 supplies current to the motor 14 to raise the electrode 10. If the current to the electrode 10 decreases, the plate current in the corresponding valve decreases. The motor 14 is then supplied with current in the reverse direction, and operates to lower the electrode.

Title: Improvements in or relating to translucent sheet materials
IPC: E04C2/54
Filed: 1956-05-04
Abstract: 859,365. Transparent sheet materials, particularly for cloches and glasshouses. ASH, A., and LODGE, G. C. O. April 30, 1957 [May 4, 1956], No. 13944/56. Classes 20(1) and 20(3) Translucent sheet material for use as cloches or for glazing greenhouses and made e.g. of glass or plastic such as polythene or polystyrene, is formed with a number of hemispherical convexities 20 which trap considerable quantities of light rays having large angles of incidence to the general plane of the sheet and that would otherwise, with a flat sheet, be reflected and lost. The thickness of the sheet is substantially constant over its entire surface, and the convexities are spaced from their neighbours by a distance equal to at least twice the diameter of a convexity in order to avoid one convexity shielding another. The convexities 20 may be arranged in patterns or in staggered or rectilinear rows. For ventilation purposes one or more of the convexities 33, Fig. 9, may be removable. The sheets may be provided with marginal portions which are free from convexities and which have pegs or grooves, &c. for interfitting to form cloches. The sheet may have an underside pressure sensitive. adhesive layer so that it can be affixed to the glazing of an existing greenhouse. The convexities may be of different shape, e.g. ellipsoids, pyramids, trapezoids, cones with-rounded tops, &c. When used for cloches the sheet may be moulded of curved or angled formation, or there may be a semicylindrical sheet arranged along the top edges of two flat sheets. Alternatively, the sheet may be moulded with a weak band of reduced thickness enabling the sheet to be hinged. A cloche may be formed with a top made with one material and sides and ends formed of another material, the materials being chosen for their resistance to ultra-violet light.
