Title: Improvements relating to the separation of benzol from coke oven and like gases
IPC: C10K1/04
Filed: 1938-08-22
Abstract: 518,368. Gas-condensing process. MAIURI, G. Aug. 22, 1938, No. 24650. [Class 55 (ii)] Benzol is separated from coke oven and like gases by gradual cooling by heat-exchange with a refrigerant, e.g.,liquid ammonia evaporating along a range of temperatures into an inert gas, e.g., hydrogen flowing in contra-flow heat exchange with the coke oven gas. Benzol or toluol is fed at m<2> into the gas as it enters at f, a chamber e containing a finned evaporatorpipea, fed with liquid ammonia at b and with hydrogen from a pipe c, evaporated refrigerant and hydrogen leaving by pipes d<1>-d<5> to give temperatures of -60‹C. to -20‹C. Unevaporated ammonia passes out at a<3>. The coke oven gas passes through outlets e<1> to a pipe h, and cools entering gas by downward flow through one of two tubular heat exchangers o<1>, o<2>. Entering gas is pre-cooled by passage up the other previously cooled heat-exchanger and melts ice to remove naphthalene left therein. The gas then passes down a pipe v and up the heatexchanger where it is cooled by treated gas to the pipe f. Valves q, p control the gas flow and treated gas passes to outlet u. Liquid condensed in the chamber e passes by a pipe i with a warm water jacket i<1> to a vessel j, whence benzol passes by a pipe k<1> to a vessel k and is pumped to a vessel k<4> whence it passes by a siphon m to the chamber e. Water is decanted at l. Specification 494, 693, [Group XIII], is referred to.

Abstract: 388,447. Distributers for seeds. LEAKE, H. M., South Lodge, Queen Edith's Way, Cambridge. Sept. 2, 1931, No. 24663. [Class 6 (i).] Seed drills of the kind described in Specification 333,645, [Class 6 (i), Cultivating implements &c.], are provided with means for temporarily opening the discharge apertures in the distributer chamber to the full extent to allow obstructions to pass, and with improved means for vibrating the rotary feed members in the chamber. The seeds from the hopper 1 pass through openings 3 into cylindrical distributer chambers 11 each supplying two coulter tubes 2. The quantity of seeds in the open-topped chambers 11 is maintained approximately uniform by regulation of the openings 3 by shutters 4 moved by means of worm gearing and racks 6 and pinions 7. Smooth or roughened conical feeders or distributers 20 in the chambers 11 are driven from a square shaft 15 by bevel gearing 16, 17 and squared spindles 18. Springs 24 normally push the spindles 18 upwards and hold serrated discs 19 at their upper ends in contact with stationary serrated discs 25, to cause the members 20 to be vibrated vertically. The discs 25 may be moved out of contact by means of screws 29 and they have pins 27 projecting into slots 28 to prevent rotation. The boxes 14 containing the gearing 16, 17 are provided with slidable front covers. In the chambers 11 are rings 30 carrying stepped baffle members 31 of the form shown developed in Fig. 4. The baffles fill the space between the cones and the chamber walls and are movable to shut off more or less of the discharge openings 12 according to the size of the seeds and the desired rate of sowing. For adjusting the baffles 31 the rings 30 have arms 33 projecting through slots and normally held against stops 36 on an adjustable bar 37 by springs 35, the arms 33 being provided with handles so that any one may be moved away from its stop by hand to release an obstruction. The bar 37 is adjustable by means of a screw-threaded hand-wheel 39 and carries a pointer 40 cooperating with a setting scale 41. According to the Provisional Specification the baffles need not be stepped.

Filed: 1929-08-16
Abstract: 338,203. Graham Amplion, Ltd., and Rickets, W. J. Aug. 16, 1929. Directive signalling.-For the automatic correction of quadrantal, octantal, and like errors in a radio goniometer provision is made for a relative tilting movement between the search coil and one of the field coils, in the plane of the other field coil. In the embodiment, shown the quadrantal error is avoided by fixing the mean position of the field coil 10 so that it is not perpendicular to the other field coil 11 and the octantal or like errors which vary with the setting of the search coil 12 are compensated by arranging a cam 26 on the search coil shaft to vary the tilt of coil 10 through link-work 27 - - 32, the bellcrank lever 31 being friction-tight on trunnion 24, and one of its arms 35 serving as a pointer for the scale 33 carried by the trunnion. The search coil is rotated by a band 17 driven from a hand-operated dial 14 and its shaft is supported from the former of coil 11. The contour of the correcting cam 26 is determined by noting angular readings of tilt, necessary for error compensation, on the scale 33, the coil 10 having a few turns more than coil 11 in order that positive or negative corrections may be made from the mean position of the tiltable coil. The other two coils may be made tiltable instead of coil 10, and the indicating dial may be carried directly by the search coil.

Abstract: 1,029,989. Delivering measured quantities of liquid; sampling liquids. WARNER LAMBERT PHARMACEUTICAL CO. June 25, 1963 [July 2, 1962], No. 25316/63. Heading B8N. An apparatus for transferring a measured quantity of a sample from one position to another comprises a container 13 for a sample to which is added a liquid from a reservoir 17, a pump 16 for taking in and delivering the liquid and a measured quantity of sample, and valve means 18 for controlling movement of the liquid and sample as it is drawn into and delivered from the pump. A probe 14 for entering the sample container 13 is connected via a pipe 27 to the container 17 for a liquid, such as a diluent or reagent, a branch pipe leading to a plungertype pump 16. In order to withdraw a sample from the container 13, the valve 18 is opened by withdrawing the plunger, sample is sucked into the probe until is passes a restriction 28 and reaches a position before a junction point 29; during the operation of the plunger liquid is drawn from the reservoir into the pump. The valve 18 is then closed and the probe moved by suitable means until its end is over a drain 22, the plunger then being depressed sufficiently to eject only the sample into the drain. The probe is now re-entered into the container 13 and a measured quantity of sample is drawn into the probe by controlled movement of the plunger. Finally, the end of the probe is moved so that its end is over a delivery position 23 and the plunger operated to expel both the sample and the liquid, the latter washing the probe after the sample is dispensed. Several sample containers 13 are mounted on a rotatable drum 19. In the construction shown in Fig. 2, a probe 32 is connected by a pipe 63 to the measuring chamber 46 of a plunger pump 33, the plunger being connected to a piston 50 whose stroke is varied by means of an adjusting screw 48; the piston is actuated either by air pressure or suction via compressor 54. The measuring chamber is also connected via a pipe 62, passage 61 in a slide valve 37 and pipe 59 to the measuring chamber of an identical pump 34. A second probe 68 is connected to by a pipe 67, passage 66 in the valve and pipe 64 to a measuring chamber 46 of a third pump 41. The three pumps are connected via pipes 38, 39, 58 to the compressor via the valve 37. In operation, with the valve in the position shown, compressed air is fed to the pumps thereby moving the plungers so as to force diluent and reagent, contained in reservoirs 36, 42 respectively and drawn into the measuring chamber 46 on a previous suction stroke, from the chambers thereby ejecting the samples and washing the probes as described for the previous embodiment.
