Title: Process of feeding powdered material into a gaseous environment
IPC: B01J8/00
Filed: 1942-04-27
Abstract: 562,025. Conveying powdered material. INTERNATIONAL CATALYTIC OIL PROCESSES CORPORATION. April 27, 1942, No. 5629. Convention date, April 26, 1941. [Class 78 (i)] In oil-cracking apparatus a powdered acidtreated clay catalyst stored in a bin 1 passes down a conduit 4 into an injector 6 through which steam, carbon dioxide, &c. is forced from a source connecting therewith by a pipe 8. The gas-suspended clay is then propelled by a screw or fan conveyer 20, fitting with small blade tip clearance in a casing 16, into a reactor 25 by way of a one-way check valve 21, the conveyer 20 imparting to the clay vehicle a low increase in pressure. The clay mixes, as a non-coagulated powder, inside the reactor 25 with gas vapour led thereinto by a pipe 30 from a heating coil 27. The clay, together with converted hydrocarbons, leaves the reactor 25 by a pipe-line 26 to reach a cyclone separator 31, from which the clay passes by way of a regenerator 33 and a conveyer 32 back to the bin 1. The gaseous products leave the separator 31 by a pipe 35 for treatment in a fractionating column 42, from which normally gaseous hydrocarbons and gasolene are led by a line 45 to a separation drum 46 from which gaseous hydrocarbons can be withdrawn by a pipe 47 and petrol by a pipe 48. A light gas oil can be drawn off from the column 42 by a line 50 and a heavier gas oil by a line 52, this latter being returned to the furnace 27 for re-treatment. Highly refractory oil may be withdrawn by a pipe 55.

Title: Improvements in or relating to temperature measuring systems employing electric thermocouples
Inventor: WILDISH DEREK GRANVILLE
IPC: G01K7/02
Filed: 1960-02-17
Abstract: 980,451. Measuring electrically. SANGAMO WESTON Ltd. Feb. 16, 1961 [Feb. 17. 1960], No. 5645/60 Heading G1N. In apparatus for measuring a variable which is a function of two temperatures the variable is determined by measuring the temperatures with thermocouples and adding (or subtracting) their outputs the thermocouples being of different materials chosen to give outputs proportional to the appropriate function of temperature. Apparatus for measuring the operating characteristics of a jet engine comprises, Fig. 3, a thermocouple A measuring the engine tail pipe exhaust temperature Ttp and thermocouples B1 and B2 measuring the compressor intake temperature Tci. Thermocouple A is made of materials a and b while thermocouples B1 and B2, formed of materials ac and bd respectively, give an output n times the output of thermocouple A such that the signal fed to the indicator is proportional to Ttp-n Tci-(n-1)Tr where Tr is the reference temperature at the indicator (or cold junction). Bimetallic compensation may be provided at the indicator to eliminate the factor (n-1)Tr and the indicator scale zero may be displaced to give a final indication proportional to Ttp-n(Tci-15). An alternative form is shown in Fig. 4 in which the output of couple B is n times the output of couple A by appropriate choice of materials a, b, and d, thus the signal applied to the indicator is identical with that of the embodiment of Fig. 3. The prior art is described as employing two thermocouples the required ratio being obtained either by a potential divider on the output of one thermocouple or by feeding the potentials developed to the separate windings of a double wound moving coil instrument, the turns on the coils being in the required ratio, Figs. 1 and 2 (not shown).

Abstract: 376,207. Photographic shutters. KODAK, Ltd., Kingsway, London.-(Assignees of Riddell, W. A. ; 333, State Street, Rochester, New York, U.S.A.) Feb. 26, 1932, No. 5782. Convention date, March 2, 1931. [Class 98 (i).] In photographic shutter mechanism of the type in which a master member connected to an exposure trigger engages an actuating member to open and close the shutter upon movement of the trigger in one direction, the actuating member is furnished with a movable member or latch adapted to be engaged by a part on the master member so that the shutter is operated only when the trigger is moved in one direction. As shown, the trigger 4 is formed with a curved body 10, pivoted at 11, and is urged upwardly by a spring 14. A triangular master member 18, connected to the trigger 4 by a hairpin spring 25 is furnished with a stud 23 adapted to engage a cam surface 36 on a shutter actuating lever 34 and also the arm 38 of a spring latch member 37 pivoted at 36 to the lever 34. The shutter comprises a blade 28 pivoted at 30 and furnished with a pin 31 engaged by a fork 33 at the end of the lever 34. In the position shown the stud 23 lies behind the end of the arm 38. Upon depressing the trigger 4, the master member 18 is actuated through the spring 25 with a snap action ; the stud 23 first engages the end of the arm 38 and moves the lever 34 clockwise to open the shutter, after which the stud engages the cam surface 36 to close the shutter. As the member 20 returns, after release of the trigger, the stud 23 turns the latch 37 idly without operating the lever 34. Accidental operation of the shutter during the return movement is prevented by stops 43, 44 on the lever 34 and part 10 respectively. For "bulb" " exposures the travel of the master member is limited by a lug 48 on a lever 45 furnished with a pointer 3, which, when set to the "B" position, brings the lug 48 into the path of the member 18 so that the shutter blade is held in the open position until the trigger is released.
