Title: Process for the manufacture and production of anti-knock benzine by destructive hydrogenation
IPC: C10G47/00
Filed: 1936-03-31
Abstract: In the production of high grade anti-knock benzine from middle oils by a continuous aromatizing destructive hydrogenation in the presence of stationary catalysts, a decrease in the activity of the catalysts owing to accumulation of heavy products is avoided by subjecting to distillation the products issuing from the reaction space, thus separating at least part of the benzine formed from the unconverted or partially converted residue, recycling the greater and lighter part of this residue to the primary aromatizing destructive hydrogenation or to a further stage, and recycling the smaller and heavier part of the residue to the distillation while continuously removing therefrom a small fraction, preferably between 0,1 and 5 per cent of the weight of middle oil introduced as starting material. The starting material may be treated prior to the aromatizing destructive hydrogenation in order to remove substances liable to form deposits on the catalyst, e.g. by subjection to a non-aromatizing destructive hydrogenation at a lower temperature than the subsequent stage, by distillation preferably under reduced pressure with or without scavenging gases or vapours, or by distillation so as to separate the initial material into a greater and lighter part for subjection to aromatizing destructive hydrogenation and a smaller and heavier part which is recycled to the distillation while continuously withdrawing a small fraction thereof. In the latter process the products issuing from the aromatizing destructive hydrogenation may be introduced to the distillation of the initial oil.  The destructive hydrogenation is preferably carried out under pressures of 200--500 atmospheres and at 500--550 DEG  C. in the aromatizing stage and at 375--450 DEG  C. in the non-aromatizing stage.  Stationary catalysts comprising compounds of metals of the 6th group are used and in the aromatizing stage catalysts may be used which have been employed in a non-aromatizing destructive hydrogenation until their activity has decreased.  Where two stages of destructive hydrogenation are employed, the benzine from the non-aromatizing stage is preferably cut to a lower final boiling point, e.g. 150 DEG  C. than that from the aromatizing stage, e.g. 190--200 DEG  C.; the two benzines may be blended with one another or with other benzines.  In the distillation stage the volume of the apparatus and pipes used for the recycling should be equal to about 1 per cent of the daily throughput of the distillation column. The fraction withdrawn from the cycle product may be destructively hydrogenated in the liquid phase with finely divided catalysts and any middle oils in the product may be added to the initial materials of the main process.

Abstract: 712,149. Smoke detecting photo-electrically. KIDDE CO., Ltd., W. April 8, 1953 [April 18, 1952], No. 9787/52. Class 40 (3) A smoke-detecting device comprises two parallel tubes 1, 2 filled respectively with a circulating sample gas, e.g. from the crank case of a diesel engine, and a comparison gas, which may be air or another sample, and along which two radiation beams of equal intensity are directed. The ends of the two tubes are closed by common glass discs 9, 9' continuously rotated about an axis midway between the tube axes so that any deposit from the smoke is distributed on an annular section of the rotating discs, thereby reducing the intensity of the two beams equally. Consequently no spurious unbalance is produced by the deposit in an electric network containing the detectors receiving radiation from the two tubes. Any unbalance current operates a warning device, and in a modification the air drawn from two crankcases may be drawn through the respective tubes, thus producing a warning when smoke issues from either crankcase. Transparent panels in the tubes allow visual confirmation of the presence of smoke.

Abstract: 1461103 Paper-making K WATANABE 5 March 1974 [12 March 1973] 9943/74 Headings D2A and D2B To make paper which does not curl due to alignment of the fibres during manufacture, stock is fed for drainage by gravity onto a linear section 2a of a first foraminous belt 2 upstream of a rotatable porous roll 1 around which the web is formed as the stock is dewatered by centrifugal force and surface pressure between the belt 2 and a second foraminous belt 3 which converges with the belt 2 at the roll 1 to define a throat 12, the web being then passed to a transfer roll 5, subsequent to which the belts 2, 3 diverge, before passing to a porous roll 6 for transfer to a conveyor 17. The roll 6 further dewaters the web and a biassing roll 18 assists its transfer from the belt 2 to the conveyor 17. Although the fibres of an underlayer P 1  of the web become aligned, the stock in a top surface layer P 2  suffers turbulence in the throat 12 so that the fibres in this layer P 2  become randomly oriented. If two headboxes 9, 9n are used, stock from box 9 produces layer P 1  and stock from box 9n produces layer P 2 , the thicknesses of layers P 1 , P 2  being controlled by varying the quantities of stock discharged from the headboxes 9, 9n. Rolls 10, 11 can be adjusted to vary the angle (α) of the throat 12. Traps 21, 22 collect white water and traps 23, 25 collect water discharged from nozzles 24, 26 for cleaning the belts 2, 3. A composite web may be formed by providing a series of machines each transferring a web onto a common conveyor 17 (Fig. 3 not shown).

Title: Improvements in apparatus for handling flat articles
Inventor: PACKMAN PERCIVAL JAMES
IPC: B65G17/08
Filed: 1957-03-27
Abstract: 823,744. Endless-belt conveyers. HUNTLEY & PALMERS Ltd. March 25, 1958 [March 27, 1957], No. 9964/57. Class 78 (1). In apparatus for spacing at regular intervals on an endless-belt conveyer a number of identical flat articles, e.g. biscuits, the spacing is done by an escapement mechanism comprising a number of fingers, an end of each of which is moved in the direction of advance of the articles at a speed appreciably less than the speed of the articles, the ends being adapted to move in succession towards the conveyer into the path of the articles and then away from the conveyer in timed sequence, so that each article bears agianst a finger and thus has its speed reduced temporarily, and is released from the finger at a predetermined instant. The escapement mechanism comprises fingers 11a ... 11h, Fig. 1, each of which is fast on a shaft 10 mounted rotatably in discs 6, 7, Fig. 2, fast on a shaft 4. A lug 14 on each finger is urged by a spring into contact with the adjacent finger, and the shaft 4 is at such a distance from the belt that the bar 13 at each finger's end just clears the upper surface of the belt. When articles 19, 20 in contact arrive at the escapement and the article 19 bears against the bar 13 of the finger 11a, the speed of the articles is reduced to that of the peripheral speed of the bar 13. As the finger 11b moves down and engages the upper surface of the article 19, the finger yields against the action of its spring and applies a small downward force to the article. The articles then move together until the end of the finger 11a rises above the surface of the article 19. When this happens the two articles are accelerated by the belt, the article 19 to a greater extent than the article 20 due to the increased friction, so that a gap 21 occurs between them into which the finger 11b enters and the cycle is repeated. When an article is released from the fingers, the friction between it and the belt is increased by a spring-loaded roller 22. This roller is mounted in a triangular frame 23 pivoted at 24 and carrying a projection 30. This projection is forced into contact with the edge of a notched disc 8 fast on the shaft 4. When the projection enters a notch 31, the spring 27 turns the frame clockwise and the roller presses on the article. In a modification (not shown) a metering mechanism is arranged upstream of the escapement mechanism and is synchronised with it so that as the finger ends of the escapement mechanism are brought into the path of the articles, they move into the gaps between the articles created by the metering mechanism. The ends of the fingers have sharp edges instead of being provided with smooth cross-members 13. Specification 769,710 is referred to.
