Title: Improvements in or relating to the stabilisation of hydrocarbon materials
IPC: C07C7/20
Filed: 1945-01-15
Abstract: Diolefins or predominantly diolefinic hydrocarbon materials are stabilized by dissolving therein a phenolic type anti-oxidant, and a promoter therefor comprising a compound having a standard oxidation-reduction potential of 1-0.7 to 0 volts.  Formation of peroxides is inhibited and, when already present, the content is reduced.  Butadiene, isoprene, cyclopentadiene, piperylenes and their homologues are referred to.  Phenolic type anti-oxidants include phenols, alkylated phenols, polyhydroxy benzenes and hydroxy naphthalenes, for example cresols, catechol, hydroquinone, pyrogallol, naphthols and their alkyl derivatives. Promoters specified are methylene blue chloride, stannous chloride or acetate or other soluble stannous salt, mercurous and titanous chlorides, platinous, uranous, trivalent vanadium and pentavalent molybdenum salts, lower oxides of copper and iron, hydrogen sulphide and elementary sulphur.  The amount of anti-oxidant is desirably about twice that theoretically required for reduction of peroxide present, and the amount of promoter should be at least 10 per cent by weight of the anti-oxidant.  Comparative figures are given for the inhibition of the polymerization of isoprene, containing peroxide equivalent to 100 p.p.m. active oxygen, at 60 DEG  C., using 0.22 per cent a -naphthol with and without methylene blue chloride (0.03 per cent), and for the reduction of tert.-butyl hydroperoxide and isoprene peroxide in aromatic hydrocarbon solution using tert.-butyl catechol and a -naphthol, with and without methylene blue chloride or stannous chloride.

Title: Improvements relating to relay or like control systems
IPC: G05D1/00
Filed: 1936-01-18
Abstract: 470,639. Fluid - pressure servomotorcontrol systems valves. NOBLE, G. S. Jan. 18, 1936, Nos. 1641 and 8910. [Class 135] A fluid-pressure valve comprises two rotatable parts having co-operating ports for simultaneously connecting an output pipe with a pressure source and with a vent, one part being rotated by means determining the required output pressure and the other by means responsive to the output pressure. As shown in Fig. 2, a valve body 7, rotatable by an arm 7A, has an input port 15 for pressure fluid, an output port 16, and a vent port 17, and has rotatably mounted therein, with clearance, a valve spindle 1 provided with a cross port 2 which is in constant register with port 16 and which overlaps the ports 15 and 17. Spindle 1 has an arm adjustably connected to the free end of a resilient metallic bellows 20 to the interior of which the output pressure is communicated through a branch pipe 19. The spindle 1 thus follows-up the movement of the body 7 and a definite pressure corresponding to the position of the body 7 is maintained in the output pipe 18. As shown in Fig. 3, arm 7A of body 7 is connected to the bellows 20, responsive to the output pressure, while arm 13 of spindle 1 is controlled by a metallic bellows 30 provided with a tube 35 depending into a mercury bath 37. The spindle 1 is thus controlled by the atmospheric pressure. The level of the mercury can be lowered below the mouth of the tube, so as to render the device ineffective, by pulling out a plunger 39. Such a device may be applied to maintain the height of an aircraft, the output pressure controlling the elevator. It may also be applied in a submarine, the bellows 30 being exposed to the water. Figs. 4 and 5 show an arrangement wherein a rotatable valve body 44 it controlled by a bellows 56 responsive to the output pressure and is provided with input, output, and vent ports 50, 51 and 52 respectively, an inner disc valve 40 having a co-operating groove 53. As applied to maintaining the direction of movement of an aircraft, the output pressure controlling the rudder, the valve 40 carries a gimbal ring 46 in which is mounted a gyro rotor 47 which is spun by an air jet 48 fed from the groove 53 and the axis of which is substantially horizontal. The first Provisional Specification suggests that the output from a first valve may operate a second valve. It also suggests that the rotatable valve spindle may be ported by having a helical groove or grooves formed thereon, the valve body being fixed and the spindle being movable axially under the control of a diaphragm. It also states that sleeve or slide valves may be used.

Abstract: 490,997. Universal joints. POLLAK, J. E. (Thompson Products, Inc.) Jan. 19, 1938, No. 1808. [Class 65 (ii)] A universal joint comprises a housing 10 with an inner converging bearing surface 16 a stud 21 with a frusto-conical head portion 25 which tapers in a direction opposite to that of the surface 16, at least two seating elements 27, 28 having inner bearing surfaces 29 which engage the head 25 and outer bearing surfaces 30 which engage the surface 16, together with resilient means such as a spring 33 urging the seating elements in the direction of convergence of the surface 16. Rotational movement of the stud is taken on the surface of the stud head 25 and the inner bearing surfaces 29 whilst tilting movements are provided for by the surfaces 16 and 30. An enlarged portion 26 on the apex of the head 25 prevents withdrawal of the stud from the seating elements, which portion may be a washer freely rotatable on a lug integral with the head. A spring 33 acting between the closure plate 18 and the seating elements 27, 28 takes up any wear there may be on the bearing surfaces. In a modification the spring acts on a slidable member in the housing which co-operates with a ball member integral with the enlarged portion 26.

Title: Improvements in the treatment of gases containing hydrogen and unsaturated hydrocarbons
IPC: C07C7/11
Filed: 1928-11-26
Abstract: 325,817. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Nov. 26, 1928. Divided on 325,309. Unsaturated hydrocarbons are separated from gas mixtures containing them by washing the said gas mixtures, if desired under pressure, with a liquid ketone containing more than three carbon atoms in the molecule. Suitable ketones for this purpose are methyl-ethyl-ketone, methyl-propylketone, diethyl-ketone, diacetone alcohol, ketone oils, acetophenone, cyclohexanone, and methylcyclohexanone. Examples are given in which (1) a gas mixture containing 8 per cent of acetylene, obtained by the thermal treatment in the electric arc of the gas obtained in the destructive hydrogenation of coal, is washed with cyclohexanone under a pressure of 20 atmospheres in such. a manner, that while leading the liquid in a cycle, 100 litres of cyclohexanone are allowed to act on 158 cubic metres of gas per hour. The residual gas which comprises mainly hydrogen may be used while still under pressure for a process which requires hydrogen under pressure, e.g. for hydrogenation.
