Title: Process for the production of cyclohexanol
IPC: C07C35/18
Filed: 1966-04-05
Abstract: 1,135,475. Cyclohexanol. CHEMISCHE WERKE HœLS A.G. 5 April, 1966 [6 April, 1965], No. 15009/66. Heading C2C. Cyclohexanol is prepared from cyclohexene by (a) oxidizing cyclohexene with an oxygencontaining gas in the presence of up to 1% by weight of a dissolved heavy metal salt at 40- 60‹ C. until a conversion to cyclohexenyl hydroperoxide of 5-30% has taken place; (b) decomposing the cyclohexenyl hydroperoxide at 20-50‹ C. in the presence of the unreacted cyclohexene with another 1-5% by weight (on the peroxide) of a soluble heavy metal salt which is added in several small portions; (c) separating the Cyclohexanol formed and hydrogenating it by a conventional method. Suitable heavy metal salts are salts of copper, tin, mercury, lead, bismuth, iron, cobalt, manganese, molybdenum and nickel with, for example, benzoic acid, left.-butyl benzoic acid, naphthenic acids, octene acids and cumic acid, particularly salts of lead and cobalt.

Title: Improvements in annealing and malleabilizing castings and other iron articles
IPC: C21D1/40
Filed: 1922-05-29
Abstract: 198,558. Sowers, O. May 29, 1922. Annealing.-Iron articles particularly castings are annealed and rendered malleable by the passage of electric current of high density, shunts being provided to render the density approximately constant over parts of the articles of less cross-section. The invention is described with reference to the treatment of a casting, for a soda pot, whilst in the mould. Chills 10 are inserted in the mould, and are of such shape that the combined section of the chill and casting is approximately uniform. Current is supplied to the chills at 12. When manganese is absent the castind is allowed to cool to the transformation point (from 1400‹ to 1800‹ F. for different grades of iron) and is then maintained at this temperature for a considerable period. When manganese is present the casting should be allowed to cool past this point and is then reheated electrically to the required temperature.

Title: Improved fluid pressure braking apparatus
IPC: B60T15/04
Filed: 1956-05-15
Abstract: 794,782. Fluid-pressure brakes. WESTINGHOUSE AIR BRAKE CO. May 15, 1966 [May 18, 1955], No. 15048/56. Class 103 (1). Fluid-pressure brake contro apparatus comprising the usua brake pipe 1, and main reservoir 2, includes also a reductioi limiting reservoir 3, an equaliz ing reservoir 4, a first or tern porary suppressive reservoir 5 a second reduction reservoir 6 a timing valve device 7 associ ated with a timing reservoir 8 a suppression valve device 9 associated with reservoir 10, a stop reservoir 11 and a timing reservoir 12. Included in the various sections of the casing indicated generally at 23 are a service application valve 32, a brake pipe cut-off or double heading valve device 33, a first service cut-off valve 34, an equalizing valve device 35, a brake pipe maintaining cut-off valve 36 and a cut-off valve 37. The brake valve handle 39 may be moved to any one of five control positions and the operation of the control apparatus is characterized primarily in that " flat maintaining operation " or means whereby the brake pipe pressure is maintained against leakage at the value of pressure prevailing in the equalizing reservoir 4 takes place at all times when the control handle 39 is in the " First Service " position, and also when the handle is in the " Lap " and " Service " positions, provided also that the handle 138 of the maintaining valve 36 is in cut in position whereby the check valve 129 is unseated to supply fluid at feed valve pressure from passage 132 to passage 88. The " flat maintaining action " is brought about by the fact that the pressure in the brake pipe 1 is, under certain conditions, existent in space 99 below the diaphram 95 of the equalizing valve device 35 and the pressure in an equalizing reservoir 4 is connected to space 97 above the diaphragm 95. Thus, if the brake pipe pressure in space 99 falls below a certain value, diaphragm 95 is depressed to unseat valve 111 and allow feed valve pressure in pipe 88 to restore the brake pipe pressure to its required value. The timing valve device 7 is controlled through train stop signal circuits (not shown) acting on an electromagnet 13 and includes a pneumatically operated whistle 19. The suppression valve device 9 may be as described in U.S.A. Specification 2,322,042 and the apparatus includes a first service cut-off valve device 34 which in closed position disconnects passages 91, 92 so that in such position fluid under pressure cannot be supplied from the first suppression reservoir 5 to the pipe 93 and suppression valve device 9 even though the brake valve handle 39 is moved to first service position. Thus an improper suppression of an automatic train control brake application is positively prevented.

Title: Improvements in or relating to Automatic Tracking Radio Equipments
Inventor: MARK JOHN RICHARD
IPC: G01S3/32
Filed: 1967-04-04
Abstract: 1,171,401. Aerials; radar. MARCONI CO. Ltd. 24 Jan., 1968 [4 April, 1967], No. 15376/67. Headings H4A and H4D. [Also in Division H1] In an automatic radio tracking equipment the effect of conical scanning is obtained by deriving signals from received signals which correspond respectively to circularly polarized TE 11  waves and to TM 01  waves in a waveguide. These waves are separated and are then recombined with a relative phase shift between them which is cyclically varied. There are derived from the resultant signal error signals which are used to correct the tracking. As described, a flared conical horn 1 is the active element of a Cassegrain type aerial which comprises a main paraboloidal reflector 3 and a secondary reflector 4, and which may be used in co-operation with a communications orbitting satellite. The horn 1 is integral with a circular waveguide 2, capable of supporting both the TE 11  and the TM 01  modes, which is continued into a circular waveguide 5, capable of supporting only the TE 11  mode, and which is provided with a mode coupler 8 for extracting the TM 01  mode. In the waveguide 5 is a circular polarizer and beyond it is an orthogonal coupler 9 with a branch 7 into which communication signals TCS for transmission at, for example, 6 Gc/s., may be introduced, and a branch 10 with a filter 11 into which the received signal at, for example, 4 Gc/s. are extracted. The received signals are amplified in a parametric amplifier 12 giving an output RCS of communications signals and, through a filter 13, another output of tracking or beacon signals, which are fed to one input of a waveguide coupler 16. Beacon signals are also extracted from the output of the TM 01  mode coupler 8, by means of a filter 14, and are fed through a ferrite variable phase shifter 15 to the other input of the waveguide coupler 16. The phase shifter 15 is controlled by a stepped voltage from a power amplifier 18 and a waveform generator 17. The voltage steps correspond to four 90 degree phase intervals, and the effect is, that as the TE 11  field rotates, the TM 01  field is combined with it to displace the phase centre outwards from the axis of the horn 1. The two outputs of the waveguide coupler 16 lead, respectively, to a matching load 19 and to a tracking receiver 20, whose output is taken through a gating or switching system 21, controlled by the waveform generator 21, to two comparators 22, 23. One comparator gives an output corresponding to errors in elevation and the other gives an output corresponding to errors in azimuth.
