Title: Process and apparatus for recovering hydrocarbons from gas streams
IPC: C07C7/12
Filed: 1959-02-18
Abstract: <PICT:0876188/IV (b)/1> Liquid fractions are removed from a main gas stream by passage alternately through one of a plurality of beds of adsorbent material, the beds are regenerated by a heated regenerating gas circulated in its own closed circuit containing means for heating the gas at least part of the time and the regenerating circuit and main gas stream are placed in communication with each other so that gas flows in one direction or the other according to the relative pressures.  The removal of liquid hydrocarbons, e.g. from natural gas is referred to.  In Fig. 1 the main gas stream enters by line 11 and is diverted by valve 12 through line 13 or 14 to one or other of adsorbing beds 10 and 10a.  The treated gas leaves through valve 16, cools the regenerating gas in heat exchanger 19 and leaves by line 20.  The regenerating gas from line 22 passes through the other bed and is cooled in air cooler 30 and heat exchanger 19.  Condensed liquid is separated in separator 32. The gas is then heated in heater 21 to aid regeneration.  The heating causes an increase of pressure which causes gas to flow through the communication means 41 to join the main gas stream upstream of the adsorbing bed so that no liquid is lost.  After a time the regenerating gas is no longer heated so that the bed is cooled ready for adsorption and gas is drawn into the regenerating circuit thereby diluting it in vapour content and improving the regenerating properties.  In an alternative embodiment (Fig. 2 not shown) the valve 12 is omitted so that the communication means becomes line 13 or 14.

Title: Improvements in or relating to magnetic tape recording and reproducing apparatus
Inventor: WILLIS DONALD WESLEY
IPC: G11B23/28
Filed: 1957-02-20
Abstract: 818,554. Phonographs &c. DECCARECORD CO. Ltd. Feb. 20, 1958 [Feb. 20, 1957], No. 5790/57. Class 40 (2). A spool 12 for magnetic tape recording and reproducing apparatus is provided with a detachable identification member comprising a soft iron ring 16. This coacts with a label device 18, but not with an alternative label device 19 to show whether the tape is suitable for recording on or not, e.g. whether the tape has already been used. The spool has a drum portion 10 containing three holes 14. These holes contain springs 15, by means of which pins inserted in the holes are retained by a frictional grip. The ring-shaped identification and labelling members 16 and 18, 19 as above each have three pins 17, 21, 22 respectively engaging in the holes in the reel. These pins are of such lengths that while items 16 and 18 can be simultaneouslv accommodated on a reel as in Fig. 2, the longer pins of item 19 prevent the simultaneous attachment of item 16. Spools of recorded tape are intended to carry one or other of the items 18, 19, while spools of unrecorded tape carry the alternative item 19, 18, with or without item 16 as appropriate. While these attachments give a visual indication of the state of the tape, item 16, being of ferro-magnetic material, co-operates with inductive circuit detection means (not shown), comprising a transformer, an amplifier and a relay switch, fitted as part of the apparatus, which permits or prevents recording on the tape, according to the presence or absence of the member 16.

Title: Improvements in or relating to the surface treatement of aluminium and aluminium alloys
IPC: B41N3/04
Filed: 1930-02-21
Abstract: The surface of aluminium or aluminium alloys is treated by first rubbing the surface, preferably with a rotating brush, with a material, e.g. a thick cream comprising a mixture of 10 parts of pumice powder, one part of calcium hydroxide and water, to produce a fine grained surface, then immersing in a bath consisting of a mixture of sodium hydroxide and sodium phosphate and finally in a bath consisting of nitric acid and alum.  The first bath preferably contains 2 oz. sodium hydroxide and 1/2 oz. sodium phosphate per gallon of water, and the second bath 2 drams nitric acid and 1/2 oz. powdered potash alum in 36 oz. water, the temperature of the baths being about 90 DEG  C.  The prepared surface may be used for offset colour printing without the prior application of a white ink base and for all photolithographic processes, for decorative purposes, e.g. as a base for photographic printing, painting, stencilling, spraying or for stamping, embossing, engraving or enamelling.

Title: Spin dryers
IPC: F16P3/10
Filed: 1975-04-25
Abstract: 1508973 Machining safety devices CREDA ELECTRIC Ltd 25 April 1975 [8 Feb 1974 24 Jan 1975] 05835/74 and 3260/75 Heading F2J A spin dryer has a safety device to prevent operation unless an inner lid 12 and an outer lid 5 are closed and latched respectively at 8, 14 in their closed positions and prevent release of the latch 14 of the inner lid 12 during operation to prevent the inner lid 12 from being opened while the drum 4 is rotating at a dangerous speed (e.g. in excess of 60 R.P.M.). As shown the inner and outer lids 12, 5 are hinged to an outer casing 1 and have latches 14, 8 respectively engaging a top cover 2 of the casing 1. In use, to load the machine and assuming that the outer and inner lids 5, 12 are closed, a user lifts first the outer lid 5, after releasing latch 8 at release member 9, and then the inner lid 12 after depressing a push-button 17 which, via a coupling member 28, releases the latch 14. When articles to be spun are loaded into the drum 4, closure of the outer lid 5 effectively, via a downwardly extending projection 10, also closes the inner lid 12 whereby the inner lid 12 is locked via its latch 14 to the top cover 2 before the final closing and latching movement of the outer lid 5 additionally, via a rod 7 connected to the outer lid 5, energizes a drive motor and releases a brake (both not shown) for high-speed rotation of the drum 4. During this high-speed drum rotation a vane 25 pivoted at 22, 23 and carrying the coupling member 28 is deflected by the current of air set up by the rotating drum 4 such that the coupling member 28 is moved to a position where it cannot be engaged by the manual release push-button 17 so that the inner lid 12 cannot be opened. When the spin drying operation is complete, opening of the outer lid 5 de-energizes the motor and applies the brake to the rotating drum 4, the vane 25 remaining in its deflected position until the drum rotation has dropped below the safe value of 60 R.P.M. or has ceased altogether. The push-button 17 can now be operated to release the latch 14 of the inner lid 12 which can now be opened since the coupling member 38 on the vane 25 is now again aligned with the push-button rod 18 and latch 14, and the articles within the drum 4 may be removed. Figs. 4 and 5 (not shown) illustrate a very similar arrangement with the addition of a downwardly directed finger (134) on the pivoted vane (127), which finger (134) is arranged in close proximity to the drum 4 whereby eccentric movements of the rotating drum (104), both during its normal rotation and especially during its slowing down period after its motor has been de-energized by opening the outer lid (105), serve to engage and deflect the finger (134), irrespective of air movement, to additionally maintain the vane (127) in its deflected position to prevent opening of the inner lid 109, as before, until the drum (104) has practically stopped rotating.'

Filed: 1918-04-13
Abstract: 129,393. Pearson & Son, S., Smith, J. S., and Hackford, J. E. April 13, 1918. Drawings to Specification. Oils for burning.-In the production of liquid fuel comprising coal tar pitch and like distillates dissolved in creosote or other solvent, coal of various kinds, including cannel coals, slack or other pit refuse, petroleum pitch, coal tar pitch and other coal products, are heated in a retort or still at a furnace temperature of about 750‹ C. for about 8 hours, and the distillates condensed and collected. The furnace temperature is then raised rapidly to 850‹ C. and so maintained for 2 hours or more. Combustion is then stopped and the heat of the brickwork allowed to complete the distillation. Superheated steam is preferably introduced at 850‹ C. to carry over heavy vapours and gases. The second distillate is dried and mixed with the first, and the product is dissolved in creosote or other solvent, forming a liquid fuel which is suitable for marine firing with known fuel-burning arrangements. Coal tar pitch may be pre-heated and run into the retort.

Title: Method of and circuit for controlling the electrolytic current in an electrolytic bath
Inventor: KAPPEL MARIO
IPC: C25D21/12
Filed: 1959-02-24
Abstract: 871,203. Automatic control systems for electrolytic baths. RIEDEL, A., and BACHMANN, F., [trading as RIEDEL & CO.]. Feb. 24, 1959, No. 6323/59. Class 38 (4). In an electrolytic bath, the current density at a cathode is maintained constant by controlling the current to the bath in dependence on the potential difference between a reference electrode and the cathode. As shown, a reference electrode 10, having a glass diffusion membrane and immersed in a buffer solution is connected by a syphon 11 to a position in a bath 1 adjacent to the surface of a cathode 2. The potential between the cathode and the reference electrode is compared with that of a constant voltage source 9 and the out-ofbalance voltage applied to a high-resistance input of a regulator 8, the output of which controls a servo-motor 6 positioning a slider of a resistor 5 through a worm-and-nut 7. The resistor 5 varies the current through the bath from a source 3 so as to maintain the reference electrode potential constant. It is stated that for a given arrangement of bath the current density is constant when the reference electrode potential is maintained constant. The syphon 11 is composed of an insulating material such as polyvinyl chloride.

[Class 80 (ii)] A one-revolution combined friction and positive clutch for a clicking press or other machine comprises a main shaft 10 carrying fixed to it a hub 12 with a sliding bolt 14 for actuating a friction clutch, and a pawl 16 for actuating a positive clutch for securing a driving flywheel 18 to the shaft 10. The bolt 14 is actuated by a manually movable tripping lever 50 and two cam blocks 52, 54 on the machine frame. The lever 50 carries a latching lever 56 with tail 57 engaged by a cam 58 on the hub 12 and a tripplate 59 co-operating with a trip-plate 60 on a lever 62. The pawl 16 is pivoted on a stud 41 on the hub and is urged outwards by a spring plunger 42 in the hub. The pawl carries an extension 45 engaging a cam 46 on the machine frame which allows the, plunger 42 to push the end of the pawl 16 into the path of teeth 48 on a ring 20 on the flywheel and positively clutch the shaft 10 to the flywheel. A light brake 72 is permanently applied to the shaft 10. Operation. Raising a starting rod 61 lifts the lower end of the lever 50 free of the bolt 14 which moves axially under spring pressure to turn a lever to tighten a friction band 24 and rotate the shaft 10. The cam 58 lifts the tail 57 to disengage trip-plates 59, 60 and a spring 63 restores the lever 50. As soon as the bolt engages the cam 52 it is pushed back to relieve the friction clutch to aid the engaging of the positive clutch. The extension 45 of the pawl 16 drops into a recess 47 and the pawl moves out and engages the teeth 48. The ring 20 of the flywheel is rotating faster than the hub 12. When the bolt 14 has passed the cam 52 the friction clutch is re-engaged and both clutches are operative until pawl extension 45 reaches the edge 49 of the cam 46 which pushes in the pawl and disengages the positive clutch. The friction clutch is disengaged as the end of the bolt 14 reaches the cam 54. The momentum of the parts restores the mechanism to the position shown in Fig. 2. The friction clutch may be disengaged after the positive clutch. Specification 22023/05, [Class 31], is referred to.
