Patent GB-912762-A (GB)
Title: Heat exchange apparatus
Inventor: SHERLAW WILLIAM
IPC: F02C7/14
Filed: 1960-07-12
Abstract: 912,762. Cooling systems for engines. ROLLS-ROYCE Ltd. July 5, 1961 [July 12, 1960], No. 24316/60. Class 64 (3). [Also in Group XXVI] Oil supplied to the bearings of a gas-turbine engine 10 is cooled in a heat-exchanger 18 by means of fuel flowing from a reservoir 16 through a pipe 17 and the pass 18<SP>1</SP> of the heatexchanger 18 to an outlet pipe 19 leading to the burners of the gas turbine, a valve-controlled by-pass pipe 46 being provided in the pipe 19 so that part of the fuel may be returned selectively to either the reservoir 16 or to the inlet of the heat-exchanger 18 via pipes 51 and 52 respectively. The capacity of the reservoir 16 is much greater than that of the pass 18<SP>1</SP>. A pump 33 pumps oil from a tank 32 through a duct 45 to an annular manifold 44 surrounding the bearing 31 of the turbine shaft 30, the oil then passing along the interior of the shaft which it leaves via a manifold 39. The returning oil passes through a duct 38 to a valve 35 which returns it to the oil tank either through the pass 18<SP>11</SP> of the heat-exchanger 18 or through a by-pass duct 41. The valve 35 and the valve 50 in the fuel by-pass pipe 46 are controlled in accordance with the temperature of the fuel leaving the heat-exchanger by means of a thermostat 57 which is set so that at low fuel temperatures all of the oil and all of the fuel entering pipe 46 pass through the heatexchanger. As the temperature of the fuel rises an increasing amount of fuel from pipe 46 is returned to the reservoir, correspondingly less being led to the heat-exchanger, and a diminishing amount of oil, reducing to zero at a fuel temperature greater than 75‹ C., flows through the latter. Additional features of the apparatus include main and backing fuel pumps 26 and 22, a pressurizing valve 47 in the fuel by-pass pipe 46 and a one-way valve 53 in the pipe 52.

Title: Termination for high energy particle linear accelerators
IPC: H05H9/02
Filed: 1962-06-25
Abstract: 997,673. Linear particle accelerators. VARIAN ASSOCIATES. June 25, 1962 [June 29, 1961], No. 24355/62. Drawings to Specification. Heading H1D. A travelling-wave linear particle accelerator has a terminating section of waveguide in which all the residual wave energy is absorbed completely. The usual output feeder is not then required and the beam focusing solenoid can be readily slipped over the accelerating structure; also the accelerating structure is free to expand. The terminating section of a disc-loaded waveguide is itself disc-loaded and to provide the attenuation the walls may be of magnetic stainless steel, or coated, e.g. in strips of gradually increasing thickness and by spraying on previously sand-blasted surfaces, highly resistive metal powder, e.g. of stainless steel, iron or aluminium-iron-chromium or cobaltiron-nickel alloy materials. In other methods the loading discs made of or coated with highly resistive material or they may be grooved or they may have smaller apertures than the discs of the main accelerating section of waveguide to reduce the group velocity of wave propagation. In further methods mentioned, the terminating section may include a ferrite isolator or may be loaded with resistively coated ceramic members or the thickness of the discs increased over that in the accelerating section. A plate may be provided at the end of the terminating section to reflect residual wave energy, but the section is designed to absorb the reflected wave before it can enter the main accelerating section. Cooling is provided for the terminating section and cooling channels may be provided in the discs. The waveguide structure may be within a separate vacuum envelope or the walls of the guide may constitute the vacuum envelope. The accelerated beam may be passed through a continuation of the envelope or through a particlepermeable vacuum window.

Filed: 1937-09-07
Abstract: 483,454. Valve gear. AEROPLANI CAPRONI SOC. ANON., and FUSCALDO, O. Sept. 7, 1937, No. 24366. Convention date, Oct. 6, 1936. Addition to 481,786. [Classes 7 (iii) and 7 (vi)] The electromagnetic fuel-injection valve described in the parent Specification is modified by forming the seating-head 8<1> of the valve i outside the injector body so that the valve is closed by its spring in a direction opposite to that in which the fuel flows to the nozzle. Further, the valve may be controlled by two solenoids, the current in one of which may be reversed for opening and closing the valve. Again, the lift of the valve may be varied for regulating the fuel injection, by means of an adjustable screw abutment. This method of regulation may be used in conjunction with the variation of the duration of injection described in the parent Specification ; or the pressure in the feed tank may be varied.

Title: Television apparatus
Inventor: LAND EDWIN HERBERT
IPC: H04N11/00
Filed: 1961-07-06
Abstract: 985,622. Colour television. INTERNATIONAL POLAROID CORPORATION. July 6, 1961, No. 24528/61. Heading H4F. A colour television system is based on the " red-white " theory of colour reproduction disclosed in article " An Astonishing New Theory of Colour," by F. Bello in Fortune, May, 1959. The original image is analysed in terms of relatively long and relatively short visible wavelength light to produce corresponding electrical signals and is reproduced by means of cathode-ray tube light-emitting elements which produce red and minus red (i.e. white minus red) light, the method of operation being such that the relatively long wavelength image is reproduced in red light and the relatively short wavelength image is reproduced in achromatic (i.e. white) light. In a first way of carrying out the invention the original image is analysed by means of red and green filters (specifically a filter which is opaque to wavelengths less than 580 mÁ and a filter which transmits in the band 480-600 mÁ), the " red " signal is applied to control the red light-emitting elements whilst the " green " signal is applied to control both the red and minus red light-emitting elements so as to produce white light. In a second way of carrying out the invention the red filter is replaced by a yellow (i.e. red plus green) filter (specifically a filter opaque to radiation less than 510 mÁ), so that the " red " signal contains information about the green components of the image, and the " red " and " green " signals control the red and minus red lightemitting individually without the need for the dual control by the " green " signal which is employed in the first method. In effect the electrical cross-connection at the receiver in the first method is replaced by an optical crosscoupling at the transmitter in the second. The transmitter may employ two orthicon cameras in association with a half silvered mirror and filter or a dichroic mirror. The receiver may employ a shadow-mask type of cathode-ray tube with suitably selected phosphors, although reference is made generally to other arrangement. Transmission may be physical circuits, e.g. coaxial cable, or by radio waves. Reference is made to the use of the N.T.S.C. system of colour television with two of the three colour components selected in accordance with the principles of the invention.
