Title: Hydrogenation of oxyheterocyclic compounds
IPC: C07D309/04
Filed: 1959-07-03
Abstract: Furan, methylfuran and dihydropyran are hydrogenated to give tetrahydrofuran, methyltetrahydrofuran and tetrahydropyran respectively by contacting the starting compound in the vapour phase, in the presence of a reduced nickel catalyst and furfuryl alcohol or tetrahydrofurfuryl alcohol, with a hydrogen-containing gas at a hydrogenating temperature below p  120 DEG C.  Preferably the catalyst is obtained by reducing a nickel catalyst such as nickel hydrate at a temperature below about 450 DEG C, reoxidising it by passing a gas containing free oxygen over the reduced catalyst and again reducing it by passing a gas thereover containing free hydrogen at a temperature below about 250 DEG C.  The catalyst may be used as such or supported on usual carriers.

Title: Electric switch-gear
IPC: H02B11/18
Filed: 1924-09-30
Abstract: 243,125. British Thomson-Houston Co., Ltd., Trencham, H., Heath, H. C., and Newton, C. W. Sept. 30, 1924. Sliding switch-carriage arrangements.-Relates to electrical switchgear including a circuitbreaker which may be moved in relation to a fixed switchgear structure for isolating purposes, the circuit-breaker being adapted to be moved horizontally to a position from which by vertical movement it can be connected in a selected circuit. As shown in Fig. 1, the circuit-breaker 17 is adapted alternatively to connect a feeder 13 to 'duplicate bus-bars 12, 14 and is arranged for horizontal movement on rails 16 which, after the circuit-breaker has been moved to either of its alternative positions, may be raised in order that the plug connections on the circuit-breaker may engage the sockets corresponding to the feeder and the selected bus-bars. The circuitbreaker is fitted with wheels 19 to roll along the rails 18 which carry nuts 21 working on vertical screwed rods 22 which are rotated through bevel gearing 24 by operating shafts 48 carrying handles 25. A shaft 48 is provided at each side of the circuit-breaker and the two shafts are being interconnected by a chain 23 so that rotation of either handle rotates simultaneously the four rods 22 so raising or lowering the circuit-breaker. To prevent vertical movement of the circuit-breaker in positions other than the two alternative positions at which the isolating connections may be established, guide plates 31 are provided thereon which may only move upwards when between pairs of rollers 33. The bus-bar and feeder sockets are provided with pivoted gravity-controlled shutters 27, 28, 29 covering bus-bar and feeder sockets. These shutters are joined together by links 41, the centre shutter having operating rods 34 attached to pivoted levers 36 normally projecting between the rollers 33 so that they are moved aside on upward movement of the circuit-breaker to open the shutters corresponding to the feeder and selected bus-bar the remaining shutter remaining closed as the movement of the feeder shutter merely moves a pin 38 along a slot 39 in its connecting link 41. Another interlock is provided to prevent downward movement of the circuit-breaker when closed which may be as shown in Fig. 3 where a pivoted cam 47 is attached to a sliding spring-pressed lever 44 cooperating with the tripping bridge 46 of the circuit-breaker trip gear and engages the shaft 48 during the downward movement of the circuitbreaker which is tripped at the commencement of such movement. A second cam projection 49 similarly ensures the tripping during the initial upward movement if the circuit-breaker has been closed for trial purposes when lowered. For earthing the feeder, conducting and insulating extensions are placed on the appropriate insulating terminals of the circuit-breaker, the terminals carrying the insulating extensions being directly connected together in any suitable way with the tank 17.

Title: An improvement in or relating to hydraulic dampers
Inventor: WALSHAW TERENCE
IPC: F16F9/50
Filed: 1969-05-07
Abstract: 1279981 Hydraulic dampers T WALSHAW 7 May 1970 [7 May 1969] 23236/69 Heading F2S In an hydraulic damper of the kind in which fluid flow through damping ports 40 can be bypassed by flow through larger apertures 38, 39, the means controlling the by-pass action includes two magnetically-coupled members 25, 27 one inside and one outside the damper housing. The housing is a cylinder of the tube-within-a-tube type, the member 25 is a control tube located within the hollow rod 23 of a piston 22 containing the damping ports 40, and the member 27 generally surrounds the damper and is slidable along the piston rod. The magnets are 26 and 29, the former being secured to the tube 25 and the latter to the member 27. Springs 28 mount the member 27 as a tuned mass-spring system which undergoes substantial displacement only at a predetermined frequency. Such displacement causes, through magnetic coupling, a following movement of the tube 25 to close apertures 38 and 39 which normally provide a flow path from one side of the piston to the other. These apertures are in the wall of an inner tube 24 secured to the piston. Thus, the piston movement is substantially undamped except at the resonant frequency of the massspring system 27, 28. In use on a vehicle, this frequency would be matched to the natural frequency of the sprung weight. (For Figure see next page)

Patent GB-603729-A (GB)
Title: Improvements relating to the drying of hydrous oxide gel particles
IPC: B01J2/00
Filed: 1945-09-14
Abstract: Wet microspherical hydrous oxide, e.g. silica and/or alumina gel particles, are dried in the presence of a substantial proportion of dry gel particles, preferably 5-30 p.c. by weight. As shown, wet gel from a filter 1 passes through a mixer 2 to a rotary drier 3 heated internally by gases from a gas or liquid fuel and air fed furnace 4. A portion of the dried product together with oversize agglomerates removed by screen 13 from the remainder are recycled <PICT:0603729/III/1> by conveyers 10 and 11 to the mixer 2.  The hopper 16 receives the dried product and gel trapped in the cyclone 17 and bag filter 20 through which drier exhaust gases are drawn by the fan 23.  Inlet and exit gas temperatures of 500-1000 DEG  F. and 250-600 DEG  F. are specified.  The process reduces the percentage agglomeration well below the 30-100 p.c. found without the admixture. Direct or indirect fired rotary driers, tray driers, belt chamber driers with co-current or countercurrent flow and tumbling drum, screw conveyer or kneader type mixers may be used.  Large particles may be screened from the mixture before passing to the drier and recycled to the mixer.  The spherical gels are useful as catalysts in fluid catalyst processes for hydrogenating, dehydrogenating, alkylating and cracking hydrocarbons, reforming and desulphurising naphtha and hydrogenating oxides of carbon.  A statement of prior art refers to drying in the presence of solvents, e.g. kerosene, alcohols, ketones, &c., or surface-active agents, e.g. lecithin or sulphonic acids.
