Filed: 1955-06-17
Abstract: 839,622. Turbines. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Aug. 21, 1956 [June 17, 1955; April 13, 1956], Nos. 17472/55 and 11320/56. Class 110 (3). [Also in Groups II and XXXIV] A fluid turbine drives a rotary machine comprising a rotor 1 and a stator 2. The rotor of a centrifuge (see Group II) is supported by a fluid bearing formed between a hemispherical end of the rotor and a hemispherical depression in the stator. Air is supplied to the bearing by a pipe 41 and a ring of ducts 43, and air is discharged from the bearing through ducts 44 some of which are connected by channels 44 to an annular collector channel 48. Driving air from a pipe 37 enters a chamber 38 in the bottom of the rotor and passes to reaction nozzles 39. Blades 40 on the stator reverse the direction of the spinning air exhausted from the nozzles, and this reversed air acts by skin friction to form a second stage impulse turbine. In a modification the rotor is formed with a series of blades to increase the efficiency of the second stage turbine. Tilting of the rotor causes some of the nozzles 39 to be occluded by a ring 51 formed on the stator so that a torque is automatically applied which tends to right the rotor.

Title: Improvements in reciprocating piston pumps, in particular for the injection of fuel
IPC: F02M59/32
Filed: 1958-06-03
Abstract: 870,383. Fluid-pressure servomotor-control systems. BESSIERE, P. E. June 3, 1958 [June 12, 1957], No. 17733/58. Class 135. [Also in Group XXVIII] The stroke of the piston 6 of a fuel-injection pump (see Group XXVIII) is varied in accordance with the speed of the engine. A gear pump 22 driven from the engine supplies fluid to a chamber 21, the flow from which is controlled by a throttle 29 formed by a slidable piston member 28. The piston member 28 is loaded by a spring 30 towards a stop 33 and the pressure in the chamber 21 also acts through passage 36 on the end of the member 28 tending to reduce the throttle passage. The chamber 21 houses a piston 23 which is connected to a rack 25 such that movement of the piston causes adjustment of a rod 18 to vary the stroke of the pump piston 6. In operation, as the speed of the engine increases, so will the pressure in the chamber 21 which acts to reduce the throttle passage 29 and thus cause a further increase in the chamber pressure with a consequential adjustment of the position of the piston 23. In an extreme position the piston 23 opens a by-pass port 38 which corresponds to no delivery of the pump. The end of the rack 25 may be connected to a dash-pot device. The groove 29 may be replaced by conjugate sections such as triangles, or semicircles in the member and conduit.

Patent GB-813645-A (GB)
Title: Process for regenerating and reactivating platinum catalyst in a reforming process
IPC: C10G35/085
Filed: 1956-06-08
Abstract: In the regeneration of a platinum catalyst by burning carbonaceous deposits formed on it during the reforming of hydrocarbons, the pressure in the catalyst chamber is reduced to sub-atmospheric before and after the regeneration step.  A sub-atmospheric pressure of 1.5-10 inches mercury absolute may be maintained for 10 mins.-2 hours.  This prevents deactivation of the catalyst by simultaneous contact with carbon dioxide and hydrogen at elevated temperature.  A purge gas may be passed over the catalyst after the first pressure reduction and also before the second pressure reduction.  The purge gas may be nitrogen or flue gas and should be free from hydrogen and oxygen and contain less than 12 per cent by volume of carbon dioxide. The combustion step is carried out by adding controlled amounts of oxygen to nitrogen or flue gas so as to maintain the temperature below 1100 DEG  F.; the oxygen content may be initially 1 per cent by volume and may be increased up to 10 per cent or higher.  Gas obtained from the burning step or by the combustion of methane or natural gas may be used as the flue gas.  If desired, the burning step is followed by contacting the catalyst at elevated temperature with an oxygen-containing gas having a partial pressure of oxygen of at least 1 atmosphere.  A hydrogenrich gas is passed over the catalyst before regeneration to remove hydrocarbons and also after regeneration in order to activate the catalyst before re-use.
Patent GB-969678-A (GB)
Title: A method for producing light-weight building elements
IPC: B28B1/54
Filed: 1962-05-09
Abstract: A method of producing light-weight building elements, particularly building stones, from blowable granular materials (e.g. expanded clay) comprises heating the material to such an extent that it attains a pyroplastic condition at the outer surface without losing its granular structure, and then immediately after reaching this condition it is filled into moulds and compacted by compression, tamping, or vibration. In a modification of this method the material is heated until the particles are pyroplastic throughout their whole mass, in which case the treatment can be carried out continuously, e.g. in an extrusion press.
