Title: Improvements in or relating to hydroforming
IPC: C10G35/14
Filed: 1951-12-19
Abstract: <PICT:0715211/III/1> A continuous process for hydroforming a naphthenic naphtha comprises contacting the naphtha in the presence of a hydrogen-containing gas with a fluidized bed of catalyst, stripping contaminated catalyst withdrawn from the reaction zone to remove volatile hydrocarbons and hydrogen, regenerating the stripped catalyst as a fluidized bed with a regeneration gas to remove a portion but not all of the deposits, and then returning the regenerated catalyst to the reaction zone.  As shown, contaminated catalyst (for example molybdenum oxide on alumina gel) is withdrawn from the reactor 7 through line 21 into stripper 22 where it is treated in countercurrent with steam introduced at 30; filters for removing solids from the stripping gas are situated in the expanded portion 31 of the stripper.  Stripped catalyst is conveyed by compressed air entering at 24 into regenerator 25 where the deposits are burned off at a temperature not exceeding 950 DEG F. so as to leave 0.5-2 per cent. by weight of carbon on the regenerated catalyst; a cooler 29 may be provided. The catalyst leaves the regenerator by pipe 28 and mixed with the hydrogen feed to the reactor in line 8.  The stripping stage may last for 20-30 minutes and may also be carried out with hydrogen or flue gas.

Title: Process for the thermal-catalytic conversion of gaseous or liquid hydrocarbons into gases consisting mainly of carbon monoxide, hydrogen and possibly methane
Inventor: GERHOLD MAX
IPC: C10G11/22
Filed: 1960-08-30
Abstract: In a process for producing hydrogen containing gases from liquid or gaseous hydrocarbons, the starting material is converted to a gas containing carbon monoxide and hydrogen and possibly methane in a first exothermic stage at 1200 DEG  to 1600 DEG C. with oxygen or an oxygen-containing gas and with or without steam and/or carbon dioxide and wherein there is sprayed a solution of mixtures of salts of organic acids or alcoholates of elements of the 2nd, 3rd and 4th Periodic Group with those of heavy metals of the 6th, 7th and 9th Periodic Group, in an amount such that 0,5 to 20,0 gms. of solid catalyst substance are used for each kgm of hydrocarbon to be converted, and the resulting gaseous mixture after a further addition of oxygen or oxygen-containing gas with or without steam and/or carbon dioxide is passed at 1000 DEG  to 1500 DEG C. over combustion catalysts to remove soot from the gases produced in the first stage. The combustion catalysts are preferably pure or mixed oxidic compounds of elements of the 6th, 7th and 8th Periodic Groups and particularly CR2O3 supported in moulded bodies of a carrier having a porosity of 30-50% and so that 0,4 to 5% of the catalyst is present on the surface of the moulded bodies.  The reaction in the first stage may be effected in a reaction vessel having walls made of zirconium silicate and may be carried out at a pressure of 5 to 20 atmospheres and in the presence of hydrogen or a hydrogen-containing gas preferably a portion of the gas produced in the second stage. The oxygen supplied to the process may be supplied as a liquid under pressure.  Hydrogen may be recovered from the gas produced by cooling the gas to 340 DEG  - 400 DEG  C. and reacting the carbon monoxide with steam to form hydrogen and carbon dioxide, the carbon dioxide being then removed by washing.  In an example the catalyst used is a 16% aqueous solution of calcium acetate, magnesium acetate and nickel acetate having CaO:Mgo:NiO:1:3:7.

Title: Improvements in or relating to fluid pressure brake devices
IPC: B60T17/04
Filed: 1937-11-02
Abstract: 504,936. Fluid - pressure. brakes. BOSCH AKT.-GES., R. Nov. 2, 1937, No. 29902. Convention date, Nov. 2, 1936. [Class 103 (i)] The cut-off valve 10 in the brake pipe 6 of a trailer is automatically returned to the position permitting braking by a spring 15 and by the admission of pressure fluid to the brake pipe from the tractor when the brake pipe is coupled up. When the trailer brake pipe 6 is disconnected from the tractor the release of fluid from the normally charged brake pipe causes a valve 5 to connect the reservoir 9 to the brake cylinder 1 and apply the brakes. To move the trailer by hand the brakes must be released by turning the cut-off valve 10 which connects the reservoir 9 by pipe 11 to the brake pipe 6 and the valve 5 is operated to connect the brake cylinder to atmosphere. In case the valve 10 should be left in this position with the pipe 6 closed to the tractor when trailer and tractor are coupled the valve-return spring 15 is provided as shown in Fig. 3. The spring 15 is not strong enough to turn the valve 10 until pressure fluid is admitted to the space 17 by passage 16 from the tractor in order to release the valve from its seating. The Specification as open to inspection under Sect. 91 describes an arrangement having a valve 15 which is sufficiently strong to turn the valve 10 without admission of fluid above the valve. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to nuclear reactor control rod winding mechanisms
Inventor: FREER JOHN
IPC: G21C7/14
Filed: 1958-09-19
Abstract: 929,174. Nuclear reactor control rods. ENGLISH ELECTRIC CO. Ltd. Sept. 14, 1959 [Sept. 19, 1958], No. 30052/58. Class 39 (4). [Also in Group XXX] A nuclear reactor control rod winding mechanism comprises a winding drum journalled in a supporting structure for winding a cable supporting a control rod on to and off a spirally grooved outer surface of the drum, drum driving means mounted on the supporting structure for rotating the drum, means for causing the drum to move along its axis of rotation as it rotates so as to maintain the cable pay-off position at substantially the same position relative to the supporting structure, and guide pulley means for guiding the cable on to and off the drum at the pay-off position. In Fig. 2 the winding drum 45 carrying the cable 22 rotates about a spirally grooved shaft 46 and is secured to the shaft by a nut 49 of the recirculating ball type so that as the drum rotates it moves axially as the nut 49 rides up the groove in the shaft 46 and the cable pay-off position remains fixed. To facilitate deceleration as the drum reaches its lowest position a compression spring 60 is provided between collars 52, 61 mounted on the drum and the splined driving shaft 53 respectively. The driving means comprises a constant speed motor 62 carrying a gear pinion 63 which engages gear teeth on the circumference of a disc member 65 which drives a cylindrical member 72 through a captive ball 71; at the other end of the shaft carrying the cylindrical member 72 is a worm gear driving the splined driving shaft 53 which rotates the drum. The cage constraining the ball 71 is mounted on one end of a shaft 77 and is urged towards the central position by a compression spring 79; the other end of shaft 77 carries a roller which bears on a cam 81. Thus the position of the ball, and therefore the speed of the driving shaft 53, depends on the profile of the cam 81. The cam 81 is moved vertically up and down with the drum 45 and is so shaped that the rate of change of the reactivity of the reactor with movement of the control rod is substantially constant for all positions of the control rod. To allow the control rod to be released in an emergency an electromagnetic clutch (not shown) may be inserted in the driving shaft 53.

Abstract: 459,251. Valve amplifying circuits. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and EDWARDS, G. W., and ESPLEY, D. C., c/o General Electric Co., Ltd., Wembley, Middlesex. Oct. 31, 1935, No. 30082. [Class 40 (v)] In an amplifier of the type shown, the gain is rendered constant throughout a range of frequencies. It is assumed that the product gZ of the mutual conductance g and the coupling impedance Z is independent of frequency, the quantities g, Z being normally themselves constant. Variation in gain is usually produced, however, by the impedances Z1, Z2, of which Z1 usually comprises a biassing resistance R1 shunted by a decoupling capacity C1, while Z2 comprises the resistance R2 of the high-tension supply shunted by a smoothing- capacity C2. According to the invention, in order that the gain may be constant the relation R2/R1=C1/C2=Zg is established. The resistances may be afforded by ganged rheostats.

Title: Method and apparatus for treating ic engine exhaust gas
IPC: F01N3/18
Filed: 1971-06-28
Abstract: 1349088 Purifying I C engine exhaust gases UNIVERSAL OIL PRODUCTS CO 28 June 1971 [29 June 1970] 30155/71 Heading F1B Exhaust gases from an I.C. engine, e.g. a spark-ignition but especially a compressionignition engine of a vehicle, are delivered through a converter 1 having a catalyst bed 12 therein. Secondary fuel from a tank 5 is introduced through injector 6 when the temperature of the converter, during warm up, is insufficient for efficient catalystic conversion but sufficient to initiate combustion of the secondary fuel without separate ignition (e.g. above 316‹C). Thus the temperature of the converter is raised to a high value (e.g. 399‹C) at which the introduction of secondary fuel is stopped until the temperature falls to say 385‹C. The means controlling the introduction of secondary fuel comprises a fuel pump 4 and a temperature sensor 2 which controls operation of the pump via a switch 3. Alternatively, or additionally, the fuel tank may be pressurized so that the introduction of secondary fuel can be controlled by a valve 31 via switch 3 and sensor 2. There may be two injectors 6 and the sensor 2 may be located in inlet 10. The sensor may be replaced by one which senses a temperature-dependent condition of the engine, e.g. fuel pressure of throttle setting. The secondary fuel is turned off when the engine is inoperative by means associated with the ignition switch of the vehicle. The secondary fuel may be Diesel fuel, propane, butane, pentane, hexane, octane, methanal, ethanol, acetane, methyl ethyl ketone or mixtures of these.
