Title: Improvements in or relating to Information Transmission Systems
Inventor: BULL ERIC WILLIAM
IPC: H04N9/30
Filed: 1965-05-15
Abstract: 1,151,221. Television. ELECTRIC & MUSICAL INDUSTRIES Ltd. 6 May, 1966 [15 May, 1965], No. 2061/65. Heading H4F. In an information transmission system including a cathode-ray or other tube having a target or screen and scanning means which produces a raster on the target or screen, the total effective aperture (as determined by optical elements and the scanning spot of the system) being different at different points of the raster, the scanning means is such that the scanning velocity is so related to the total effective aperture that the highest frequency of electrical system which can be derived as displayed by the target or screen is approximately constant. In general, the total effective aperture increases with displacement from the centre of the target or screen. By matching the scanning velocity to the aperture the highest frequency of the electrical signal may be made to correspond to the maximum bandwidth of the system. The invention is applied at both the transmission and reception ends of the system. Reference is made to the use of mirrors or lenses to concentrate the information at the centre of the scanned area for transmission and to restore the correct spatial position after reception. The raster may be produced by a spiral scan, and in accordance with this invention adjacent rings are arranged to be spaced by a distance equal to the effective aperture. As a consequence both radial and tangential velocities are proportional to aperture. As an alternative, the rings may be equally spaced by a distance determined by the maximum aperture, i.e. the aperture at the edge of the raster. With this arrangement only the tangential velocity is proportional to aperture. When using a conventional television type of raster, the line period is kept constant, so as to maintain normal synchronizing facilities, but both the line spacing and line velocity are varied so as to become greater with increase of distance from the raster centre. The non-linear scans required by the invention may be generated by the digital scan technique disclosed in Specification 952,737.

Title: Improvements in relief valve assemblages for liquid-filled cooling systems
Inventor: STEADMAN CLIFFORD STUART
IPC: F16K17/00
Filed: 1953-07-29
Abstract: 745,250. Valves. SMITH & SONS (ENGLAND), Ltd., S. July 29, 1954 [July 29, 1953], No. 20994/53. Class 135. A relief valve assembly for liquid-filled cooling systems such as those used in conjunction with internal combustion engines for motor vehicles comprises a main valve loaded so as normally to close a main vent passage but adapted to open the passage when the pressure in the system increases to a predetermined value, and an auxiliary valve capable of being set in either of two operating conditions to control an auxiliary vent passage. In the first condition, the auxiliary valve is open to vent the system unless the temperature in the system rises above a predetermined value. In the second condition the auxiliary valve is closed whatever the temperature unless the pressure in the system falls below a predetermined value. The assembly is particularly suited for use in systems where the coolant is also used for heating purposes, e.g. to heat the interior of a vehicle, for it may be arranged to give both adequate cooling of the engine and adequate heating of the vehicle under both summer and winter conditions without the use of separate summer and winter thermostats. As shown, the main valve 16 comprises two portions 17, 18 separated by a shoulder 19 forming an abutment for the loading spring 22 and also a seat for the auxiliary valve which is constituted by a sealing ring 37. The upper portion 17 of the main valve has vent apertures 21 and is loosely mounted on a boss 4. The main valve seats on a ring 14 carried by an inturned flange on a cylindrical member 11. The member 11 has a flange 12 which is swaged over a flange on a cup-shaped member 8 having vent apertures 9. The member 8 and a spring 6 are secured to the usual filler cap 1 by the boss 4 which is swaged over at 5. The flange 12 engages a sealing ring 15 carried by a filler pipe 2 having a vent 3. The sealing ring 37 is secured by a hexagonal boss 36 to a plate 35 forming the upper wall of an air-filled expansible chamber completed by a metallic bellows 34, and a cup-shaped member 33. A cup-shaped member 30 with diametrically opposite tongued spigots 31 is brazed to the member 33. The spigots 31 are slidable in cut-outs 28 in an apertured member 23 held in the valve portion 18 by annular projections 24, 25. The auxiliary valve is then closed by the loading spring 38 as shown on the left-hand side of Fig. 1. If the member 30 is then pulled down and turned through 90 degrees so that the tongues 39 of the spigots 31 engage the narrower cut-outs 29, the spring 38 is prevented from closing the auxiliary valve as shown in the righthand half of Fig. 1. In this case, which corresponds to summer conditions, the auxiliary valve is only closed upon the temperature in the system reaching the predetermined value.

Abstract: 1515571 Vacuum depositing semi-conductors MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 19 May 1975 [23 May 1974 7 June 1974 (2)] 21146/75 Heading C7F [Also in Division H1] In molecular beam epitaxial deposition of a compound semi-conductor the conductivity type or composition of a selected region 22 of the epitaxial layer is caused to differ from that of the remainder 21 of the layer by the selective heating, during deposition, of the region 22 by means of a beam 30 of concentrated energy such as an electron beam or laser beam. In one Example Ge-doped GaAs is epitaxially deposited on a GaAs substrate 2 using molecular beams from respective Ge and GaAs sources. Firstly a uniformly n type layer 20 is deposited on the pre-heated substrate 2 using no concentrated energy beam, but when the beam 30 is scanned across the region 22 during a second deposition stage the Ge deposited in the additionally heated region 22 becomes an acceptor (Ge being an amphoteric dopant in GaAs) and the resulting layer has a p type strip 22 in otherwise n type material 21. In another Example GaP and GaAs sources are used for the molecular beams to deposit a GaAs x P 1-x  mixed crystal. When an area of the surface is selectively heated by a beam of concentrated energy the material depositing on the selected area contains a higher concentration of P (i.e. lower value of x) than elsewhere in the layer. An Al molecular beam may additionally be used in this example. Preferred apparatus, temperature conditions, &c., are disclosed for both Examples.
