Title: Method of separating liquids by thermal diffusion
IPC: B01D17/00
Filed: 1953-05-27
Abstract: In separating a liquid into two fractions by thermal diffusion in a column between two walls spaced uniformly apart at 0.01-0.15 inch and maintained at different temperatures, the liquid is introduced at one end of the column, a first fraction is continuously removed at the other end of the column, and a second fraction is continuously removed from the feed end, the ratio of rate of removal of the first fraction to the rate of feed being less than about 1.5:10 by volume. The feed is introduced at the top or bottom of the column adjacent one of the walls and the second fraction is withdrawn adjacent the other wall.  The feed rate is preferably at least equal to the normal rate of thermal circulation.  Four separation columns may be used in parallel, or two in parallel and the small portions combined and led to a third column from which the large portion is recycled with the main feed.  Graphs show the effect on the degree of separation of the small fraction withdrawal rate, the feed rate, and the ratio between these rates.  The separation of a petroleum lubricating oil is described and reference is also made to the concentration of stigmasterol from soy bean oil, and the separation of odorous substances from a fish oil.

Abstract: 1392717 Fluid dampers; Bowden mechanisms JOSEPH LUCAS (INDUSTRIES) Ltd 21 April 1972 [14 May 1971] 15034/71 Headings F2S and F2K A damper comprises an outer tubular flexible component 11 and an inner flexible component 12 extending within and movable relative to the outer component 11, a clearance between the components being filled with a viscous fluid 13 having a viscosity not less than 20,000 centistokes (e.g. a silicone liquid thickened with finely divided silica) which resists sudden relative movements of the components 11, 12 but permits gradual movements. The components are the inner core and outer sheath of a Bowden cable, which transmits movements of a first device 14 to a second device 15. A gradual movement of the device 14 is transmitted by the core 12 to the device 15, the viscous fluid acting as a lubricant for the relative movement of the core 12 and the sheath 11. Rapid movement of the device 14 is not trasmitted to the device 15, since the corresponding rapid movement of the core 12 is resisted by the viscous fluid 13, but is instead absorbed by a resilient coupling 16. If the altered position of the device 14 is maintained then the resilient coupling 16 exerts a force on the core 12, and so the core and the device 15 move gradually as permitted by the viscous liquid 13.

Title: Improvements in or relating to railway signalling systems
IPC: B61L3/18
Filed: 1937-06-01
Abstract: 498,034. Railway signalling systems. STANDARD TELEPHONES & CABLES, Ltd., GRIFFITHS, J. B., and BROWN, A. June 1, 1937, Nos. 15219 and 30450. [Class 105] A continuous line circuit extends along the track and the trains are provided with a front signalling equipment comprising a measuring device M and means EP for applying electric power to the continuous circuit and with a rear equipment, which may be a speedometer-controlled low-impedance shunt I across the continuous circuit, varying the characteristic of the circuit fed by the front equipment of a following train so that the measuring device of this following train gives an indication of the safe distance ahead ; the measuring device is segregated from the low-impedance shunt of its own train, for example by rectifiers RC inserted in the continuous circuit at intervals less than the distance between the front and rear equipments of a train. The integrity of the continuous circuit is verified by providing high-impedance shunts HR across the circuit at intervals and the train is not allowed to proceed unless the measuring device shows more than a predetermined minimum current. The continuous circuit may be provided by a line SC and an earthed running rail ER; the front and rear equipments of a train have brush contacts SL engaging the circuit and the rectifiers are tested by two spaced brushes with a voltmeter therebetween. If the voltage is abnormal a warning is given and a marking on the track may be effected. To guard against failure the rear equipment is provided with a plurality of low-impedance shunts. The measuring device may be operated by the phase condition of the current. Fig. 2 shows an indicator with a red sector H controlled by the receiving equipment and with a red sector S controlled by a speedometer. As the actual speed approaches the permitted speed a green background G is progressively covered by the red sectors and finally contacts are closed for automatic braking. If the continuous circuit is out of order or broken the sector H moves reversely and uncovers a red background. At track points the signalling circuit is connected to the particular route set up; when the points are open a track shunt is placed on the signalling circuit. Cabin indications may be given by equipment, similar to the front equipment, connected to the circuit; for example to indicate a train in the approach to points the equipment would be connected some distance before the points. At curves or gradients the characteristic of the circuit may be modified to impose appropriate speed limits. A set of relays may be used instead of a current indicator to respond selectively to the magnitude of the current. The receiving equipment may control the propulsion motor. The connection between the train and the line circuit may be inductive.
