Abstract: 1420149 Dual brake valves CLAYTON DEWANDRE CO Ltd 16 April 1974 [19 April 1973] 19057/73 Heading F2F A dual brake valve which controls two independent circuits actuating separate sets of brakes has two valve assemblies operable simultaneously through a balance beam 1 displaced by pedal-actuated input plunger 3 and at least part of a reaction force is created by a reaction mechanism other than through the beam. As shown, each valve assembly comprises a plunger 7 one end of which forms an exhaust valve seat 8 which when engaged by a poppet type valve element 9 cuts off communication between a brake connected port 12 and an exhaust connection 15. Further movement of the element 9 lifts the head thereof from an annular valve seat 11 to establish communication between an accumulator connection 13 and port 12. The beam 1 is pivoted to a carrier 5 forming part of the plunger 3 and spring biased reaction pistons 17, 18 accommodated in a bore 16 act on the carrier 5 through a pad 5a to provide the reaction force independent of beam 1. A passage 19 leads from one end of bore 16 to the port 12 of one valve assembly and the space between pistons 17, 18 is connected by a passage 20 to the port 12 of the other assembly. If the fluid pressure into passage 19 fails, piston 18 provides the reaction, and if fluid pressure to passage 20 fails, piston 17 transmits reaction through piston 18. A passage 23 provides a visual indication of failure of either of seals 22.

Title: Process for the manufacture of polyhydric alcohols of the cyclopentano-polyhydrophenanthrene series
IPC: C07J75/00
Filed: 1937-07-13
Abstract: Polyhydric alcohols of the cyclopentano-polyhydro-phenanthrene series are prepared by the action of agents adding on oxygen on unsaturated compounds of the etiocholane or pregnane series and if necessary hydrolyzing the products so obtained.  The unsaturated link may be present either in the side chain or in the nucleus, or the compound may be unsaturated in both the side chain and in the nucleus.  The expression agents adding an oxygen includes organic peroxides such as per-benzoic acid, per-phthalic acid, and per-acetic acid.  Hydrogen peroxide and osmium tetroxide may also be used.  In the latter case the reaction takes place in absolute ether, and the osmium ester formed is saponified with neutral sodium sulphite.  In examples (1) androstendiol-diacetate is added to a chloroform-perbenzoic acid solution and allowed to stand at room temperature for 18 hours.  The solution is then extracted with caustic soda, washed, and evaporated to give a mixture of two isomeric oxides of androstendiol diacetate; (2) 17 - ethinyl - 3 acetoxyandrostenol - (17) is hydrogenated in the presence of palladium to give the corresponding ethenyl compound, which is then treated with per-benzoic acid in chloroform solution to give the isomeric dioxides of 3-acetoxy-17-ethenyl-androstenol-(17). The oxides are hydrolyzed by heating in a bomb tube in an aqueous medium.  Samples have been furnished under Sect. 2 (5) prepared as follows (1) an ethereal solution of 3 : 17-dihydroxy-17-ethenyl androstane is treated at room temperature with osmium tetroxide for 2 days. The osmium ester so produced is reduced with sodium sulphite to give on crystallization 3.17.20.21-tetrahydroxy-allopregnane (sample 1a).  The mother liquors on concentration gave 3 : 17-dihydroxy-17-aldehydo-androstane (sample 1b); (2) 3 : 17-dihydroxy - 17 - ethyleneoxide - androstane is heated in a bomb tube for 20 hours with water at 190-200 DEG  C. to give the corresponding glycol; (3) a chloroform solution of monoperphthalic acid is allowed to act on a chloroform solution of 3 : 17-dihydroxy-17-ethenyl-androstane to give the corresponding glycol; (4) to a carbon-tetrachloride-ether solution of 17 - ethenyl - 3 : 17 - dihydroxy - androstene-(5 : 6) there is added a carbon tetrachloride solution of bromine followed by osmium tetroxide.  The precipitate is heated with zinc dust in ethanol solution, filtered, and crystallized to give tetrahydroxy pregnene.  Specification 467,790 is referred to.

Title: Improvements in and relating to electric control circuits
Inventor: KURZ WALTER
IPC: H01H47/24
Filed: 1953-07-16
Abstract: 739,915. Switching systems. LIGHTACTUATED SIGNAL & SWITCHGEAR CO., Ltd. July 16, 1953, No. 19726/53. Class 38 (4). [Also in Group XL (b)] In a device wherein a sensitive relay supplied for example by a photo-electric cell operates a relief relay and a contact of the relief relay operates a control circuit, the relief relay is provided with a contact for locking its supply which takes the supply from the contacts of the sensitive relay, the sensitive relay being provided with a drop-out contact which energizes an auxiliary -winding of the relief relay to open the control circuit if the supply to the sensitive relay fails. The invention is described with reference to a system for switching on car headlamps as darkness falls. Such a system is described in Specification 736,986. As shown, with switch 21 in the position shown, light of a certain intensity incident on photo-cell 1 closes the moving contact of sensitive relay 2 with the top contact. The supply from line 9 then extends through an auxiliary winding 7 of relay 10 thus increasing contact pressure and the winding 11 of a relief relay to earth. Contact 3 now occupies the position shown, removing the supply from the line L to the car lamps and giving relay 3 a supply alternative to that through the contacts of the sensitive relay. When the light increases, the spring-loaded moving contact of sensitive relay 2, engages with the lower contact. Auxiliary winding 7 is then energized in reversed sense so that the two contacts engage firmly. Drop-out winding 12 of relay 3 is also energized and this counteracts the winding already energized, hence the relay drops out and the supply is restored to line L. With the switch in its other position the supply is always on line L but is given to line D only when relay 3 is operated. Circuit D is provided with means for dipping the headlamps at night.
