Title: Television camera apparatus
IPC: H01J29/00
Filed: 1976-03-19
Abstract: 1507756 Image pick-up tubes PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 19 March 1976 [24 March 1975] 11150/76 Heading H1D TV camera tube apparatus includes a tube (e.g. Vidicon) having a target such that spaced portions of photoconductive material and portions of a signal electrode intermediate the p/c portions are accessible to the beam, means (e.g. switch 35) for applying two different voltages between signal electrode and electron source during scanning and flyback such that during scanning a proportion of the beam current dependent on the local degree of illumination flows into the signal electrode without the p/c material free surface potential changing and during each or one of a plurality of flybacks the potential of the surface is stabilized by the beam. The arrangement enables inherent amplification up to one decade for example by beam current adjustment. The target structure may comprise parallel photoconductive strips (13) on electrode (12), (Fig. 2, not shown), strips (13) being of PbO 20-60Á wide and 10 to 30Á thick, the intermediate portions (14) having a width equal but preferably less than the width of strips (13) (e.g. 10% the width). The pattern may be formed by p-n junctions in a Si disc serving as signal electrode, or (Fig. 3, not shown) as dots (16) on electrode (11), or (Fig. 4, not shown), an apertured electrode (20) formed by two fold vapor deposition of Ag through a wire grid rotated 90 degrees between two stages, covers partially uninterrupted p/c layer (19), or by an electrode on the window, and a grid preferably of transparent conductive material of which the p/c is formed arranged a small distance therefrom, or (Fig. 5, not shown) by non-interrupted electrode (11) coated on etched cavity plate (23) and p/c material (25) vapour deposited for example on the unetched portions. Plate 23 preferably forms the tube window and may be an optional fibre plate with etched claddings. The beam need not be focussed during flyback but must not influence the next line to be scanned. A high current beam during flyback facilitates rapid stabilization and an electron source as in Specification 1,190,186 is suitable. Defocussing during flyback may produce a spot of 10 line widths, which would be electron optically lifted during flyback e.g. using a device as in Specification 1,247,647. Stabilization need not occur every flyback but may be every other one or up to one out of ten flybacks. The tube cathode may be a cold cathode or screened filament cathode. The electron beam is scanned by e.m. coils (not shown) preferably arranged about the tube, or electrostatic electrodes (not shown) preferably in the camera tube.

Title: Method and apparatus for the aerobic retting of flax and other fibrous plants
IPC: C02F3/26
Filed: 1945-05-05
Abstract: 623,367. Retting flax &c. VERMEIREN, T. I. S. May 5, 1945, No. 11500. Convention date, March 10, 1941. [Class 120 (i)] In an aerobic method of retting flax &c., the retting water is purified by treatment with air in an enclosed space G maintained at a pressure greater than atmospheric and the treated water is then filtered at F. Used water from retting pits flows through a trough C and sieve L into settling tanks D, E. From the tank E the hard water is pumped by a pump H into a container G containing small tubes of porcelain. Air from a compressor K is led through an expansion chamber 2 and through a pipe 3 into the container G when the water and air under pressure are intimately mixed. The treated water now passes through a tube 5 into a filter F and, after passing through the filtering mass is collected at 6, heated by a steam injector 18 and then led through a pipe 8 to a feed tank B from where the retting pits are supplied. The volatile products are released from the filter F through the pipe 12. The filter is cleansed by connecting an air supply to pipe 9 and a clean water supply to pipe 18 and evacuating the rinsing water through the pipe 11 into the tank E. Manometers 13, 14 indicate the pressure difference between the top and bottom of the filter. A float 16 and switch 17 on the tank E may control automatically the pump H and compressor K.

Title: Improvements in or relating to apparatus for controlling supply of air to furnaces
Inventor: MILNE ALFRED JAMES GRAHAM
IPC: F23L17/00
Filed: 1958-04-11
Abstract: 867,717. Automatic control systems for furnaces. KELVIN & HUGHES Ltd. June 18, 1959 [April 11, 1958], No. 11574/58. Class 38 (4). In an automatic control system for varying the air flow to the combustion space of a furnace on increase or decrease of heat demand, the combustion space pressure decreases before being restored to a predetermined value. As shown, a contact 17 of a switch, responsive to the combustion space pressure, makes a circuit through a contact 18 to a relay 20 when the pressure is below a lower limit and through a contact 19 to a relay 21 when the pressure is above an upper limit. The relay 20 energizes a motor 15 to close a forced-draught damper 35 and the relay 21 energizes a motor 16 to open an induced-draught damper 36. A switch 1 is responsive to a signal from a combustion controller, as disclosed in Specification 865,631, responsive to the difference between a required air-flow for a desired heat demand and the actual air-flow. A relay 5 is energized when the actual air-flow is low causing the motor 15 to open the damper 35. The consequent reduction in combustion space pressure actuates the pressure switch to energize relay 20 to disconnect motor 15 and energize motor 16 so as to open the induced-draught damper 36 and restore the combustion space pressure to the desired value. The switch 1 and the pressure-switch co-operate to cyclically energize relays 20, 21 until the air-flow reaches the desired value. With a high air-flow a relay 6 is energized and the motor 15 energized to open the forceddraught damper 35, the consequent reduction in combustion space pressure energizes the relay 20 to energize motor 16 so as to open the induced-draught damper 36. The dampers may be replaced by fans, the speed regulators of which are adjusted by motors 15, 16. Specification 865,632 also is referred to.
