Title: Improvements in or relating to radio transmitter
Inventor: HEATON-ARMSTRONG LOUIS JOHN
IPC: H03J1/18
Filed: 1959-09-11
Abstract: 914,434. Automatic control systems. STANDARD TELEPHONES & CABLES Ltd. Sept. 11, 1959, No. 31041/59. Class 38 (4). Power is supplied from a radio frequency source through an adjustable coupling element to a variable impedance and signals proportional to the square root of the power supplied to the load and proportional to the voltage of the radio frequency source are opposed to control the coupling element to reduce variations of power with variations of load impedance. In Fig. 1 the tank circuit 6 of the final stage of a radio transmitter is maintained in resonance with the signal applied at 2 from the preceding stages (not shown), by a reversible motor 12 automatically adjusting an inductance 11 under the control of a phase discriminator 16. Tank circuit 6 is coupled to an aerial 10 through another adjustable inductance 7 and a coaxial line 9. A circuit involving a current transformer T, a potential divider 37, 38, and rectifiers 31, 32, derives a voltage E2 proportional to the square root of the power supplied to the aerial. A circuit including a potential divider 23, 24 and a rectifier 22 derives a voltage E 1  proportional to the output voltage of stage 1. Any difference between voltages E 1 , E 2  is effective through a relay 17 to run a motor 15 and thereby adjust inductance 7 in the appropriate direction to prevent variations of aerial power, e.g. due to icing. Simpler circuits for deriving a less accurate approximations to the square root of aerial power are described.

Title: Improvements in forced flow tubulous vapour generators
Inventor: EVANS RICHARD HENRY
IPC: F22B37/64
Filed: 1963-08-09
Abstract: 1,101,311. Tube walls for furnaces; steam generators. BABCOCK & WILCOX Ltd. 7 Aug., 1964 [9 Aug., 1963], No. 31515/63. Headings F4A and F4B. In a forced flow vapour generator having walls lined with horizontal tubes supported by heated vertical means and in inwardly-extend - ing hollow arch above which is an entry to a lateral gas pass, a beam is disposed within the arch and supports the wall below the arch, the beam being heated so that differential expansion between the beam and the wall is largely avoided. The frame of the arch may be constructed so that differences of thermal expansion of the frame members can be accommodated. A header 4 which is fed with fluid from an economizer supplies fluid to downcomers 5 which are in heat exchange with the wall support members 7 which may be of the form described in Specification 877,116. An arch of tubes 3 surrounds a beam 9 from which the rear wall supports 7A are suspended. The beam 9 is supported through rocking devices on transoms mounted between pairs of side wall support members 7. The arch 3 has a framework comprising members 60, 105, 89 which is supported by the beam 9 through members 61 and rockers 63 and which is attached to rear tubes 133 through blocks 129. The tubes of the arch are attached to the frame by pivotal devices 139 to permit relative longitudinal movement and are rigidly attached to blocks 135, on the members 60, to the ends 109 of the members 105 and to blocks 99 on the members 89. The beam 9 is attached to the rear wall support members 7A by a linkage 73 which permits swinging of the wall, and the members 7A are attached to the frame of the arch by a pin 93 housed in a slot 95 in the member 89. The various members of the frame are connected together by pins housed in slots. The pinned joints of the frame and the rocking connections between the tubes or the arch, the frame, and the beam 9 accommodate differences in thermal expansion of these parts. Tubes 167 and 153 from the economizer extend horizontally along the beam 9 before passing vertically down the members 7A. The beam 9 is heated by these tubes largely avoiding differential thermal expansion of the beam and the rear walls. The support members 7 and 7A are similarly heated by the adjacent tubes. In another embodiment, Fig. 6 (not shown), the linkage 73 supports a block (197) which is attached to the member 89 by the pin 93 and which supports a rear wall comprising vertical tubes. In another embodiment, Fig. 7 (not shown), the tubes are interconnected to form a membrane wall and the wall below the arch is resiliently supported to accommodate different vertical expansions between different parts of the beam and the wall.

Patent GB-316319-A (GB)
IPC: C08G63/48
Abstract: 316,319. British Thomson-Houston Co., Ltd., (Assignees of Kienle, R. H.). July 27, 1928, [Convention date]. Impregnating-compositions. - An alkyd resin containing an unsaturated oxidizable fatty acid preferably the acid of a drying oil is incorporated with a drying oil before the completion of the resinification, and may be employed as a coating or impregnating composition or for making laminated articles of paper, textiles, mica and the like, or, with fillers such as wood flour, asbestos, cotton, ground minerals, &c., for making moulded articles. The alkyd resin may be made from glycerine and phthalic anhydride, or other polvhydric alcohols such as glycol or mannitol and other polybasic acids such as succinic or malicacid may be employed. In the examples glycarine and phthalic anhydride are heated together, and, at 200 C. further phthalic anhydride and the fatty acid of chinawood, linseed, perilla or like oil is added; or all the ingredients may be mixed at one time; in either case the drying oil is added when the resin is in the A stage. When the resin contains more than 45 per cent of oxidizable fatty acid it is unimportant what part of the A stage the resin has reached. In another example an unsaturated fatty acid such as the acid of linseed oil is heated with excess of glycerine so as to form an ester, linseed oil is added and finally phthalic anhydride, the heating being continued until a drop on a hot plate (200 C.) loses all fluidity in less than five minutes. Alternatively the oil may be added in two portions, the second being added after the phthalic anhydride. When the resin contains atleast 45 per cent of oxidizable fatty acid, it can be incorporated with oil by simply heating, without special precautions. The oil solutions of the resin are, soluble in solvents such as acetone, benzene -alcohol, coal-tar oil, acetone oil, butyl acetate, butyl alcohol, ethyl lactate, glycol diacetate, glycol ethers, benzyl acetate, triacetin, diethyl phthalate, and dibutyl phthalate, and, when there is a high fatty-acid content, the oil solutions are also soluble in aliphatic hydrocarbons such as gasolene, petroleum naphtha, &c. Specifications 22544/13 and 284,349, [both in Class 2 (iii), Dyes &c.], are referred to. The Specification as open to inspection under Sect. 91 (3) (a) includes the use of a non-drying oil such as cotton-seed oil instead of the drying oil. This subject-matter does not appear in the Specification as accepted.
