Patent GB-382252-A (GB)
Abstract: 382,252. Fluid - actuated valves; piston valves. BOSCH AKT.-GES., R., 4, Militõrstrasse, Stuttgart, Germany. June 15, 1932, No. 16875. Convention date, June 18, 1931. [Class 135.] Valves controlled by pilot or relay valves.- A valve device for controlling a gas burner of the kind having a main valve actuated by gas pressure under the control of a thermally operated auxiliary valve supplying gas to a pilot burner and in which a byepass valve is provided for byepassing the thermal valve for ignition purposes has the byepass valve so arranged that when it is moved to the open position it closes the main valve either mechanically or by fluid pressure. In the form shown in Fig. 4, the control chamber 14 above a diaphragm 13 connected to the main valve 12 is fed with inlet pressure admitted through a passage 16 provided with a throttle 15 and exhausted through a passage 17 and pipe 18 controlled by a thermally actuated valve 19. The valve 19 is actuated by a thermal disc 28 secured in a casing 27 and carrying a pilot burner 29, so arranged that when the pilot burner is alight the valve is open. The byepassing valve 25 is formed as a ported piston adapted to be operated by a pushbutton acting against a spring. When this valve is depressed passages 22, 23 connect the passage 16 to a passage 21 leading to the pilot burner and a passage 24 leading to the control chamber. The passage 21 communicates with the pilot burner through a pipe 21<1> surrounding and protecting the pipe 18. In a modification a fourway byepassing valve is used arranged to pass the byepass flow through the control chamber. A construction of valve for this purpose is shown in Fig. 9, and comprises a tubular piston valve adapted to operate in a ported sleeve screwed into the main casing. The valve is operated against the action of a spring 37 by a push cap slidably engaging a flange on the sleeve, a flange 38 being provided to limit the outward movement of the valve. When the valve is depressed gas from the main conduit passes from an annular chamber 47 connected to the main conduit by a passage 20 through an annular passage 44 and central pipe 30 to the control chamber 14. From the control chamber gas passes by a passage 32 arranged at right-angles to the pipe 30, through a narrow annular passage between the pipe 30 and the outer part of the valve to an annular recess in the valve and thence to the pipe 21.

Title: Process of preparing cyclohexylhydroxylamine
Filed: 1966-08-25
Abstract: Cyclohexylhydroxylamine is made by hydrogenating a solution of nitrocyclohexane in the presence of a palladium or platinum catalyst and of a saturated amine having a pKa-value of at least 9.5. Specified amines comprise amylamine, triethylamine, piperazine, piperidine, lupetidine, morpholine and cyclohexylamine. The reaction is effected at a temperature between room temperature and 100 DEG  C. under a superatmospheric hydrogen pressure below 100 p.s.i.g. Alcohols and liquid hydrocarbons are specified solvents, but the amine may also constitute the solvent.  The proportion of catalyst is 0.025-0.25% use and the proportion of amine is at least 1%, both based on the nitrocyclohexane. The inclusion of the amine in the reaction mixture tends to repress further hydrogenation to cyclohexylamine.  Examples are given.
