Title: Fluid flow control element
IPC: F16K11/04
Filed: 1972-11-29
Abstract: 1370246 Valves ADEOLA AG 29 Nov 1972 [30 Nov 1971] 55217/72 Heading F2V A valve for supplying fluid to one face of a piston while connecting the other face to exhaust comprises first and second pairs of conical surfaces 2d, 4g; 4f, 6f into which passageways lead from ports 2c, 1a, 1c and 1d respectively, and wherein port 1d is connected to a port 8a via a valve 7f, 9a and a port 1b connects a reservoir 14 with the space between surfaces 4f, 6f. The passageways which lead into the two pairs of surfaces are alternatively closed by closure members 11 and 10 respectively and the member 10 is connected to the member 9a such that when the passageway leading from port 1d to the surface 6f is closed, the passageway from 1d to the port 8a is open and vice versa. On the working stroke, pressure fluid flows via line 13a, forces member 11 against surface 4g and flows  through 5a to port 1c and hence to piston chamber 12b. The pressure of the fluid also forces member 10 against surface 6f and a certain amount of the fluid flows into the reservoir 14. With member 10 against surface 6f the valve 7f, 9a exhausts the fluid from the piston chamber 12c. On the idling stroke, pressure fluid is cut off in line 13a and the pressure of fluid in chamber 12b forces member 11 against surface 2d and the fluid is then exhausted via port 1a. Exhaustion of chamber 12b and pressure of fluid in reservoir 14 forces member 10 against surface 4f, thus closing valve 7f, 9a. The fluid in reservoir 14 then flows through port 1b, channel 5d and port 1d to the piston chamber 12c to push the piston back into the initial position.

Title: Improvements relating to methods of producing electrically conductive layers on electrically insulating substrates
IPC: C23F1/28
Filed: 1966-12-19
Abstract: In the process for the formation of thin film resistors an insulating substrate such as ceramic glass or plastics is coated with a layer of phosphorus containing nickel by the electroless nickel plating method, and this layer is then reduced to a thickness of 1000A or less by a process of dissolution under passivating conditions.  The substrate is initially degreased and its surface sensitized by immersion in a stannous chloride solution, rinsed, and activated by immersion in a palladium chloride solution.  It is again rinsed and finally immersed in a aqueous electroless nickel plating solution containing a nickel salt and hypophosphite to cause the phosphorus containing nickel layer to form.  To reduce its thickness, this layer is immersed in a solution of IN sulphuric or IN hydrochloric acid or 1/3 molar phosphoric acid or pure water, air being blown through the solution in each case so that the rate of dissolution of the layer falls after a time.

Patent GB-584386-A (GB)
Abstract: 584,386. Continuous shale distillation processes. ARNOLD, C. (Standard Oil Development Co.). June 28, 1944, No. 12307. [Classes 55 (i) and 55 (ii)] In a process for the continuous distillation of shale, roughly ground shale is preheated and fluidized in a preheating zone by the upward passage of hot distillation gases derived from the distillation zone, into which the shale in a fluidized state passes to undergo physical disintegration with the formation of hydrocarbon vapours, the spent shale gravitating to a combustion zone where oxygen-containing gas is introduced in order that the carbonaceous deposits on the shale can be burnt to form hot combustion products to maintain the temperature in the distillation zone and fluidize the shale and the mixture of hydrocarbon vapours and hot combustion products passing from the distillation zone through the reheating zone to a fractionating zone for the recovery of the hydrocarbon vapours. As shown shale of a maximum particle size of inch is fed into a preheating and fluidizing chamber 4, from which it passes by a feed pipe 10 to the reactor 1 in which distillation occurs at the top and combustion in the presence of oxygen containing gas supplied through inlet 15 occurs at the foot, the spent shale being removed by the rotating grate 11 and outlets 22 and 17. The hot combustion products and hydrocarbon vapours at a temperature of 800-1000‹F. pass with a velocity of 2 to 10 ft. per sec. from the reactor 1 to the preheater 4 by means of the pipe 3 and pre-heat the shale to a temperature of 400-600‹ F. The gaseous mixture carries with it finely divided shale particles which serve to coat the fresh shale entering the chamber 4. The average time taken for the passage of a given body of shale through the chamber 4 is from 2 to 10 minutes and through the reactor 1, from 5 to 20 minutes.
