Patent GB-676613-A (GB)
Title: An improved process for contacting finely divided solid particles with gases
IPC: B01J8/34
Filed: 1947-02-14
Abstract: <PICT:0676613/III/1> <PICT:0676613/III/2> In processes in which finely-divided solids are maintained in a dense fluidized state in a contacting zone by means of an upflowing gas, undesirable circulation of the solids is obviated by maintaining a body of static, contiguous packing elements in the contacting zone.  The size, shape and arrangement of the packing elements are such as to define a labyrinth of tortuous passageways through which the finely-divided solids are adapted to flow freely downwardly in the absence of a fluidizing gas. The contacting zone may be partially or completely filled with packing elements and packing elements of the same or different sizes may be positioned in separate sections of the contacting zone, the packed sections being, if desired, separated by unpacked sections. Suitable packing elements which may be of a catalytically active or heat conducting material are balls, cylinders, blocks, U-shaped elements, wire turnings, wire helices and Raschig rings.  The finely-divided solids may be moved in a generally concurrent or countercurrent direction with respect to the gases.  Suitable processes are the separation of gases by selective adsorption with a powdered adsorbent, e.g. the separation of aromatics from aliphatics, of butadiene from butenes, of ethylene from admixture with ethane or propylene and of hydrocarbon fractions of different molecular weights, the drying of air, the drying and calcining of solids, e.g. limestone or magnesite to form oxides, the reduction of ores, the distillation of coal or oil shale and various chemical reactions employing a finely divided catalyst, e.g. cracking oxidation, chlorination, nitration, hydrogenation, dehydrogenation, polymerization and the synthesis of hydrocarbons from carbon monoxide and hydrogen.  Fig. 3, (not shown) shows an arrangement for passing the finely-divided solids in a generally countercurrent direction to the gases through two packed zones in series, e.g. reaction and catalyst regeneration zones or adsorption and desorption zones, the solid leaving the second zone being recycled to the first.  Fig. 4, (not shown) shows an arrangement for passing the solids in concurrent with the gases through one zone and in countercurrent through a second zone.  In Fig. 2, two separate fluidized beds C, D of solids of different size, composition or weight are maintained in a single packed reactor 10, the different solids being withdrawn at 18 and 14. Fig. 6 shows an arrangement wherein differently-sized packing elements 211, 221 are positioned in two interconnected contacting zones 210, 220, the higher density of the finely-divided solids in the zone 210 containing the larger size packing promoting a difference in fluid head between the zones with consequent circulation of the solids from one to the other as shown. Specifications 569,691, 593,180 and 676,615 are referred to.

Title: Improvements in the manufacture of sheet glass
IPC: C03B35/16
Filed: 1932-02-15
Abstract: 385,775. Glass manufacture. EDWARDS, A. E., 296, High Holborn, London.-(Naamlooze Vennootschap Mij. tot Beheer en Exploitatie van Octrooien; 57, Zeekant, The Hague.) Feb. 15, 1932, No. 4425. [Class 56.] Relates to the manufacture of plate or sheet glass by an intermittent process in which a mass of molten glass is rolled into a strip at a relatively high speed, and the strip is subsequently carried through a leer at a relatively low speed. According to the invention, a strip of glass 12, as it is formed by rolling- apparatus 10, is received on a roller conveyer 13 and carried forwards at substantially the speed at which it is formed, and it is then moved transversely on to another conveyer 22 which carries it into a leer 29 at a lower speed. The strip is moved transversely while it is still moving forwards, and the shifting may be effected by any suitable device such as a number of pushers 37 mounted on a carriage 33 that runs on rails 35. The speed of the rollers 13 may be reduced, if desired, during the shifting operation, or conversely, the speed of the rollers 22 may be increased. A second leer with its associated conveyer may be arranged on the other side of the conveyer 13, successive strips of glass being fed into alternate leers.

Title: Process for the performance of chemical reactions
Inventor: FREY WALTER
IPC: C09B47/10
Filed: 1963-02-04
Abstract: A process for the halogenation of phthalocyanines comprises reaction between a halogen, gaseous at the reaction temperature, and the phthalocyanine contained in a liquid medium which may be chlorobenzene; phthalyl chloride; stannous titrachloride; titanium tetrachloride; titanium tetrabromide; silicon tetrachloride nitrobenzene or chlorides or bromides of Group (IV) metals and semi-metals.  The reaction is performed at a temperature higher than the boiling-point of the medium at atmospheric pressure and at a higher pressure than the vapour pressure of the medium at the reaction temperature.  The reaction may be carried out at 120 DEG  to 250 DEG  C. at 2-40 atmos. with 3-40 parts by weight of medium to 1 part of phthalocyanine.  Examples refer to the production of copper chlorophthalocyanine; bromochlorophthalocyanine; iron chlorobromophthalocyanine; copper bromochlorophthalocyanine. Products are obtained as powders by distilling off the volatiles and may be purified by admixture with oleum and precipitated by addition of water.ALSO:In chemical reactions between at least one reactant gaseous at the reaction temperature and a reactant dissolved or suspended in a medium which is liquid under the reaction conditions, the gaseous reactant is introduced into, or formed within, a reactor containing said dissolved or suspended reactant, and having a reflux condenser, the temperature being higher than the boiling point of the medium at atmospheric pressure and the pressure being higher than the vapour pressure of the medium at the reaction temperature.  The escape of gases from the condenser may be controlled by a valve operated in accordance with the pressure in a contact manometer by means of a magnetic valve determining the supply of air to said pneumatic valve.  The above process may be used for the halogenation of phthalocyanines (see Division C4). The medium may be inert or may take part in the reaction.

Title: Fuel jettison apparatus
IPC: B64D37/26
Filed: 1944-03-10
Abstract: 576,143. Siphons. FLIGHT REFUELLING, Ltd., and LEGGE, C. N. March 10, 1944, No. 4523. [Class 69 (i)] A siphon, more particularly for apparatus for enabling the whole or part of the fuel in an aircraft tank to be jettisoned, is controlled by apparatus in which a charge of compressed air or gas is arranged to be discharged so that while the siphon is being filled with liquid the pressure of the charge maintains a closure of the siphon outlet until, due to continued discharge, the pressure has fallen below a predetermined value. The siphon 17 has its inlet controlled by a valve 26 normally held closed by a spring 28, and its outlet controlled by a valve 20 normally held open by a spring 21. A charge of compressed air is admitted to a container 1 through valve 4, pipe 3 and valve 29 pressed upwardly by spring 30, pipe 2 being then open to atmosphere. When fuel is to be jettisoned, the valve 4 is moved to open the pipe 3 to atmosphere so that valve 29 is closed, and to open the pipe 2 to the air supply ; air then passes through pipe 22 to act on piston 24 and open the siphon inlet valve 26, and also passes through pipe 2 to act on piston 7 and open a spring-pressed valve 9, whereupon air from the container 1 flows through pipe 11 to depress a piston 18 and close the siphon outlet valve 20, the air then passing through pipe 13 to an ejector nozzle 14 to withdraw air from the siphon through pipe 16, the siphon thus being filled with fuel. When ' the pressure in the container 1 falls sufficiently, the valve 29 opens, the'remaining pressure is dispersed rapidly and the outlet valve 20 opens to allow the fuel to be jettisoned. The flow may be stopped by moving valve 4 to admit a fresh charge to the container 1, the valve 26 then closing. Hammer from the liquid may be prevented by providing one or more ball and spring or other relief valves near the valve 20, or by means for slowing the closure of said valve..

Abstract: 955,578. Feeding webs. P.C. RIEGGER. Feb. 7,1962 [Feb. 8,1961], No. 4639/62. Heading B6B. To a moving web, whose tension is varied by a preceding operation, there is first imported a first uniform tension independent of the final tension required, then a second uniform tension dependent on the final tension, by means of an adjustable brake, the addition of these two tensions resulting in the final tension at the entry of the web into the subsequent operation. A web travelling from a roll 1 to an operating machine 6 is first fed by a pair of rollers 7, 71 at the same linear speed as that of the operating device 6. A movable roller 8 imparts the first uniform tension to the web, and a brake roller 11 co-operating with an elastic roller 12 imparts the second uniform tension. A variable resistance torque opposes the rotation of the brake roller 11 and may be supplied by an hydraulic or pneumatic circuit or by an electric apparatus (none illustrated). An hydraulic circuit may comprise a pump which forces a fluid through an adjustable spring-load valve. Movement of the roller 8 may be utilized to control the speed of rollers 7, 7<SP>1</SP> to avoid any difference of speed between the rollers and the operating machine 6, by switching on and off an electric motor which drives part of a differential gear in the drive transmission of the rollers 7, 71.

Title: Improvements relating to clothes wringers
Inventor: PLINT DENNIS JOHN WILLIAM
IPC: D06F45/18
Filed: 1957-02-12
Abstract: 884,444. Clothes wringers. HOOVER Ltd. Feb. 11, 1958 [Feb. 12, 1957], No. 4787/57. Class 138 (2). A quick release device for a clothes wringer comprises a locking device pivoted to a frame member and carrying a latching device engaging a spring urging the rollers towards one another, a release arm having two thrust surfaces and secured to pivot with a release bar in either of two directions, and means arranged that movement of the release arm in either direction will turn the locking arm to release the spring. As shown, the upper frame member 10 is urged into engagement with the lower member by the cammed end 47 of a torsion bar which engages a roller 46. The release bar has a flattened end 37 pivoted to the frame member 10 at 38 and on an extension has a pin 54 pivoted to it at 58. Also pivoted at 38 is a small channel section saddle 62 which abuts section 37 with its surface 66 and has projecting portions 64 which bear on the inside surface of a locking arm 42, pivoted to the frame at 44 and carrying roller 46. The mechanism is shown in the closed position. If the release bar is depressed it rotates about the pivot 38 and causes the pin 54 to press against the horizontal portion 58 of the locking arm 42 with the result that the locking arm rotates anticlockwise about 44 and the roller 46 is disengaged from the torsion bar. If the release arm is raised, its rotation about the pivot 38 is accompanied by an equal rotation of the saddle 62, the projecting portions 64 of which engage the inside surface of a web 48 causing the locking arm to rotate anticlockwise and release the torsion bar. In a second embodiment the release bars are connected to a release link which in one direction of movement of the bars moves the locking arm directly and in the other direction moves the locking arm indirectly. Specifications 778,170, 827,159 and 827,160 are referred to.

Abstract: 532,901. Ticket-issuing machine. BLACK, H. D. Sept. 23, 1939, No. 26518. [Class 106 (iii)] Comprises a multi-unit machine having its individual units so constructed that tickets of a given denomination can only be issued in an unmutilated condition through the unit in the machine assigned to that denomination. In the majority of multi-unit machines the feeding of the strips is effected by pin wheels or drums and in the present machine the first unit has one pin and the second two pins arranged in each transverse row. The pins pass through slots in guards and cover members between which the strip passes. Fig. 2 shows the strip for the first unit, and Fig. 3 the strip for the second unit. The strip 26 is provided with feed openings 30 adapted to be engaged by the drum pins of the first unit, the openings being on the lines along which the ticket is severed. In Fig. 3, there are two openings 32, 34 arranged on similar lines for the strip 28 of the second unit. If the strip is divided transversely into five hole positions it is seen that the second strip has holes in the second and fifth of the five positions and can only be fed through the first unit by reversal; besides, there would be no point in this since it is of lower value. Other arrangement of pin holes are described. In a final form, Fig. 8, the ticket strip 50 has the conventional feed holes 53 and additional control holes 52. The latter are engaged by a brush 54 which when a hole 52 passes makes contact with a plate 56 and the switch 60 having been closed starts the motor, the relay 58 holding down armature 66 to maintain the circuit to the end of the cycle. The holes 52 would be differently positioned for different units.
