Title: Television transmitter
IPC: H04N5/06
Filed: 1935-07-31
Abstract: 460,709. Television. RADIOAKT.- GES. D. S. LOEWE. July 31, 1935, Nos. 21691 and 21692. Convention. dates, Aug. 4, 1934 and Aug. 11, 1934. [Class 40 (iii)] The area of an optically projected image 24 of an object 3a to be transmitted is illuminated by additional constant light. The film 3 is moved continuously and the line scanned by the circle of apertures in a disc 5 is at the edge of the area which would be illuminated by rays 33 from a source 1. The unused light is removed from the main beam by a reflecting- prism 34 to illuminate a mask 35, which is projected on the area 24 by prisms 36, 39, 40 and lenses 37, 38. The intensity of the auxiliary illumination is controlled by a diaphragm 41. To compensate changes in the intensity of the light source, light falling on a white surround 43 on the mask is reflected to a photoelectric cell 44 which controls the grid bias on a valve 47 in the signal amplifier. The spacing of the scanning apertures is greater than the width of the projected image, and a number of apertures are omitted at the end of each frame, or a rotating diaphragm interrupts the light, Fig. 5 (not shown). The auxiliary illumination is of such intensity as to ensure that the aerial current falls to zero in these intervals, Fig. 2 (not shown), whatever the nature of the picture transmitted. According to modifications, the auxiliary illumination is obtained from a separate source, Fig. 5 (not shown) ; the same lenses 4, 4<1> are used for projecting the film and the mask 35, Fig. 7 (not shown). When using a mosaic-screen type of transmitter, the cathode ray sweeps an area greater than that illuminated by the image and auxiliary lighting.

IPC: B61L5/18
Filed: 1953-08-06
Abstract: 725,509. Railway signals. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., SHEPPARD, E. A., and STEVENS, S. A. Aug. 6, 1953, No. 21717/53. Addition to 676,644. Class 105. [Also in Group XI] The optical projection apparatus of the parent Specification, and comprising a transparent block consisting of a number of separate cups or shells 3e, 3f, &c. nested together one within the other, the arrangement being such that rays from the light source enter each cup or shell and emerge therefrom after reflection at the outer surface only, is modified in that each inner surface 7 is coated with a light-absorbing medium such as optical black paint. Thus, when the apparatus is used as a railway signal lamp there is no possibility of the formation of "phantom" signals by rays of light travelling down one or more of the cup elements by internal reflection at the abutting surfaces thereof and being reflected off the rear face of the lens to reemerge from the front thereof.

Title: Improvements in or relating to brakes for ground wheels of aircraft or the like
IPC: B64C25/46
Filed: 1955-07-29
Abstract: 771,779. Anti-skid brake control. SOC. D'INVENTIONS AERONAUTIQUES ET MECHANIQUES S.I.A.M. July 29, 1955 [Aug. 9, 1954; Oct. 2, 1954], No. 21940/55. Class 103 (1). A brake control device, particularly for preventing the skidding of aircraft wheels, comprises, fitted within the hub of the wheel 1, a housing C containing fly-weights 40, which when rotated and spread apart, break the electrical contact between two washers 47, the disc 37 on which the fly-weights are pivoted having a ring 55 fitted therein by grub-screws and connected to the hub member 56 by a spiral spring 58. If the wheel is decelerated rapidly, due to incipient skidding, the spiral spring 58 is coiled or uncoiled and a contact spring 71 secured to the ring member 69 moves out of contact with an insulated button 66 and engages a contact stud 66a to close a circuit. Thus, as shown in Fig. 1, circuits will be closed to energize and keep open an exhaust valve on the hydraulic line to the brake cylinder 14 so long as a switch 22 is closed by a non-compression of the undercarriage jack and the fly-weights have not been rotated sufficiently quickly to open the contact washers 47. A circuit through line 28 will also be closed to vent the brake cylinder if excessive deceleration causes contact element 71 to move off the insulated pad 66. This circuit arrangement allows for the conditions under which an aircraft bounces on landing.

Title: Improvements in or relating to a process and system for electrolytically removing material
IPC: B23H3/10
Filed: 1963-06-04
Abstract: <PICT:1004009/C6-C7/1> In electrolytically removing material from an electrically conductive workpiece with the production in the electrolyte of flocculent eroded material or sludge, the electrolyte is recovered for re-use by separating the sludge from it in a centrifugal separator and the separator is cleaned after a predetermined fixed amount of electrolytic material removal work has been completed, e.g. as determined by the number of ampere-hours consumed by the electrolysis, such that the amount of sludge produced does not exceed the separator capacity.  As shown, electrolyte drains from a pan 58 in the work area of the machining apparatus 10 into a compartment 20 of a storage tank 12 from which it is transferred by a pump 68 to a centrifugal separator 14. Sludge accumulates on the inside of the bowl 74 while the clarified electrolyte collected in the bottom of the separator housing 72 is pumped to the electrolyte supply reservoir compartment 18 of the tank 12, from which electrolyte is pumped to the machining apparatus 10. When the total number of ampere-hours consumed by the electrolysis has reached a chosen fixed value, a meter 16 causes pump 68 to be de-energized and operates a cleaning device 84 for the separator comprising a suction skimmer pipe 82 moved by a rack and pinion towards the wall of the bowl 74, the sludge being transferred to a sump 88.  When the cleaning operation has been completed, a limit switch moves the skimmer back to its original position, reset the meter 16, and restart the pump 68.  The partition 64 between the compartments of the tank 12 is made lower than the outer walls of the tank so that if electrolyte accumulates in either compartment due to malfunctioning of the cleaning circulation system overflow between the compartments occurs without overflowing the tank or stopping supply of electrolyte to the machining apparatus.

Abstract: 856,071. Refrigerating. LICENCIA TALALMANYOKAT ERTEKESITO VAL LALAT. July 14, 1958 [Dec. 14, 1957], No. 22498/58. Class 29 [Also in Group XXXV] The gaseous cooling medium 2 of a turbo-alternater 1 is cooled in a heat exchanger 3 by water which is cooled in an emergency in an evaporator 10 which is evacuated into the condenser 13 of the main turbine power plant T by a steam ejector. In normal operation, fresh cooling water 4 passes through a heat exchanger 6 and then through the hot end 8 of exchanger 3 to waste. The condensate from condenser 13 and evaporator 10, passes through the cool end 7 of the exchanger 3, and is cooled substantially to its original temperature in exchanger 6 before returning to the evaporator, an ejector 12 serving for de-aeration only. If the fresh cooling water is insufficient, artificial cooling is employed by shunting the exchanger 6 by closing valve 5 and opening valve 14 so that the condensate returns from the exchanger 3 uncooled. Simultaneously, valve 15 is opened to bleed steam from the turbine to ejector 16 to reduce the pressure in the evaporator 10 thus causing increased evaporation and cooling of the coolant, which is then recirculated by pump 11 to cool the generator
