Title: Improvements in the removal and recovery of benzene and naphthalene from gases particularly coal distillation gases
IPC: C10K1/18
Filed: 1934-01-25
Abstract: <PICT:0423328/III/1> Oil which has absorbed benzene and its homologues and naphthalene from coal gas is distilled preferably in the presence of water or steam, and the distillate which includes a portion of the washing oil is preliminarily rectified at such a temperature that only the easily boiling fractions of the washing oil go over with the absorbed products.  This distillate is finally rectified at a temperature allowing only benzene and its homologues to pass off, the naphthalene being removed in solid form by cooling the residue which together with the residues from the distillation and preliminary rectification is then returned to the washing oil supply.  Used washing oil passes through a heater 4 to a bubble tower 7 in which steam is admitted through a pipe 11.  Vapours pass to a condenser 13 and thence to a tank 15 in which water is separated from the condensates which are then supplied to a preliminary rectifier 19 together with uncondensed vapours from the condenser.  Heating coils at the base of the rectifier cause vapours to pass off through a dephlegmator 23 cooled as by cold water to a main rectifier 30 of similar type from which vapours of benzene and homologues pass to a condenser 32.  The liquid residue is discharged into a naphthalene crystallizing pan 37 and thence at room temperature into a storage tank 39 which also receives the residue from the preliminary rectification.  The residual oil from the bubble tower 7 is also returned to the storage tank after having passed through a heat exchanger 1 and a water-cooled pipe system 45.  The used washing oil is delivered from the gas scrubbers into a tank 40 and is preheated by acting as the cooling liquid in condenser 13 and exchanger 1 before being pumped to the heater 4.

Title: Apparatus for maintaining a variable at a substantially constant value

Filed: 1945-02-09
Abstract: 601,121. Automatic control systems. IGRANIC ELECTRIC CO., Ltd. Feb. 9,1945, No. 3296. Convention date, Feb. 9, 1944. [Class 38 (iv)] Variables in general.-In an automatic control system in which the value of a variable is determined by the rate of flow of a medium, the rate of flow of the medium is controlled in accordance with the value of the variable and with the rate of change of the variable, the latter effect being obtained by using a ring type liquid drag device. The Figure shows an arrangement for maintaining the calorific. value of a gas flowing in pipe 10 constant by mixing it with a proportion of air from pipe 11. The air regulating valve 13 is controlled by calorimetric device 16 which rotates shaft 18 in accordance with the calorific value of the mixed gases in pipe 12. Rotation of shaft 18 causes member 39 to rotate so that gears 43 and 44 mounted on a common freely mounted shaft 42-and meshing with segments 45 and 46 cause freely mounted member 50 to rotate, owing to the resistance of the liquid drag device 23, 24 to which segment 45 is attached and also to the increase in tension in one of springs 30 and 31. Rotation of member 50 results in the closure of one of contacts 97g and 97e preparing the circuit of one of relays 95 and 96 for energization, and the displacement of arm 61, 65, arm 61, 65 controls the phase relation between cam 76, which is continuously rotated by motor 64 through planet gears 68, 67 and 71, and directly driven cam 77, by moving planet gear 67 round the motor shaft. If there is no displacement of the system, contacts 78 and 79 associated with cams 76 and 77 remain open ; if the system is displaced however these contacts are periodically closed for a period dependent on the degree of phase displacement, so that one or other of relays 95 and 96 is periodically energized. Relays 96 and 95 control servo-motor 14 operating valve 13, so that closure of the appropriate relay contacts causes the motor to adjust the valve and restore the correct calorific value. Visual indication of any deviation is given by pointer 17 moving over scale 21. In a modification, Fig. 4 (not shown) a cam mounted on the shaft of the planet which engages a fixed follower in such a manner that arm 61 is periodically disengaged from member 57. Member 57 is given a stepped configuration, member 61 being suitably shaped to engage it.

Title: Improvements relating to machines for grinding, polishing and like operations
IPC: B24B47/04
Filed: 1932-02-04
Abstract: 387,838. Grinding, polishing, and similar machines. LUMSDEN MACHINE CO., Ltd., BLAKE, E. G., LUMSDEN, W. S., and STANIER, J. H., Hawks Road, Gateshead, Co. Durham. Feb. 4, 1932, No. 3374. [Class 60.] In machines for grinding, polishing, and like operations the grinding head or work table is traversed to and fro by continuously driven crank mechanism or the like, and at the end of each traverse a feed motion is imposed while the crank mechanism is passing the dead-centre. The surface of the work operated on corresponds to the rectangular portion A, D, C, B, Fig. 1, the long lines such as A-D representing the traversing strokes of the tool or work table, and the short lines the feed. The feed is obtained from the crank mechanism through ratchet gearing involving unequally spaced teeth on a ratchet wheel, which equalizes the feed transmitted from the ratchet gearing through a crank pin-and-slot mechanism. In the event of desiring the complete reversal of the grinding along the same path means is provided also for enabling the traverse and feed to be reversed only after the reversal of the final traverse. In a series such as is indicated in Fig. 1, the final traverse C-B is reversed along B-C before the reversed feed operates. As shown, a work-carrying table 10 is fed along a slide 11, which is supported by a crank box 12, travelling on a slide 13 on a bed 14. Reciprocation of the box 12 is obtained from a constantly rotating crank disc 18 mounted in the box on the same shaft as a worm wheel 21 suitably driven. The disc 18 has a pin 17 attached to a connecting-rod 15 capable of oscillating on a fixed shaft 16 carried by the bed 14. The disc is also provided with a pair of diametrically opposed cams 22 acting on a roller 23, carried by a pivoted link 24, attached by a link 27 to a spring-controlled pawl 28. Intermittently driven by the pawl is a ratchet wheel 29, which communicates motion to a crank disc 31 and pin 33. The pin works in a rectangular slot 34 in the work table 10 and, to compensate for the harmonic nature of the successive impulses transmitted, the teeth on the ratchet wheel are unequally spaced and a masking device or blinder is brought into operation. The motion of the pawl is constant and where the space of a tooth is less than this, the latter part only of the motion is used, a blinder 40 masking certain of the teeth. To render the feed inoperative at the end of an operation before reversal of the feed a disc 48 is provided with diametrically opposed projections 49 serving as a masking device for the pawl.
