Title: Process for producing styrene
IPC: C07C5/333
Filed: 1943-11-16
Abstract: Styrene is produced by subjecting to dehydrogenation, in the presence of a dehydrogenating catalyst, a mixture of ethylbenzene and xylene to convert the former to styrene while the xylene is substantially unconverted.  A fraction comprising ethylbenzene and p- and m-xylenes may be separated from the product of reforming or hydroforming straight-run gasoline.  After heating, the ethylbenzene fraction is contacted with a dehydrogenating catalyst such as alumina, either alone or promoted by oxides of the members of the left hand of Groups 4, 5, and 6, especially Cr, Mo, and V, in a fixed bed or fluidized by passage of the reactants. Temperatures are generally about 450-700 DEG  C. and pressures 0.25 to slightly above 1 atm.  The products are separated, for example by fractionation, to recover styrene, a xylene fraction with some unconverted ethylbenzene which may be blended with the reformed gasoline and, preferably, in part recycled to the dehydrogenation to further dilute the ethylbenzene.  Gaseous hydrocarbons may be returned to the reforming stage and heavy polymers treated to yield gasoline.  In an Example, an ethylbenzenexylene fraction containing 25 per cent of the former and obtained from the product of hydroforming a straight-run naphtha is contacted with alumina-molybdena at about 600 DEG  C. and 0.32 atm.

Title: Improved machine for producing cigarettes, cigarillos or the like
IPC: A24C5/18
Filed: 1957-06-18
Abstract: 818,806. Cigarette-making machines. KÍRBER, K. June 18, 1957 [July 20, 1956], No. 19150/57. Class 130. In a continuous-rod machine in which a tobacco stream is reversed in direction by being carried upwardly between a grooved feed wheel 1 and an endless belt 4, choking of the stream where it joins and leaves the wheel is prevented by local enlargement of the tobacco feed duct in the direction of flow. On joining the wheel, the stream is first compacted under a steel belt 8, Fig. 2, by downward inclination of the belt or tapering of the feed duct width, and on leaving the belt 8 the duct width increases up to the tip of a wheel guide-in finger 14 where the duct cross-section equals that of the wheel groove. On leaving the wheel, the duct width increases from the tip of a wheel groove scraper 15, Fig. 4, until a roller 9 feeding in a cigarette paper wrapper is reached, and then decreases up to a rod-former tongue 10 where the duct cross-section corresponds to that of the tongue. A steel belt may be provided to assist compaction of the tobacco stream to this cross-section. A corrugated or spiked brushing roller 16, scraper 18 and a suction dust extractor 17 are provided for the belt 4. The operative speeds of the belts 4, 8, the wheel 1 and a belt 12 carrying the paper wrapper through rod-forming means are individually variable and are normally equal although the speeds of the belt 4 and wheel 1 may be unequal.

Filed: 1938-06-28
Abstract: 516,577. Treating waste waters; manures. PETERSEN. K. June 28 1938. No. 19181. Convention date, June 29, 1937. [Class III] In a method and means of treating waste waters and waste materials containing organic substances of animal or vegetable origin by mesophile or thermophile anaerobic conversion to obtain combustible gases, the anaerobic conversion is substantially effected in a horizontal or slightly-inclined rotating or oscillating container into the interior of which there is no free access of atmospheric air. In the construction shown in Fig. 1, a horizontal container 11 supported on rollers 29 is adopted to be rotated by means of a gear wheel 25 and a pinion 27. The container is provided with blades 21 and grinding bodies 23. The material to be treated is fed through an inlet pipe 13. Outlet pipes 19, 15 convey from the container the treated sludge and the gas formed during the treatment. In a modification shown in Fig. 4, the apparatus is divided into three compartments, a compartment 33 where coarse and fine grinding of the material takes place, the main conversion compartment 46 and a sedimentation compartment 56. The compartments rotate at different velocities, the sedimentation compartment having a very low velocity. In a further modification shown in Fig. 5, the container 11 in which anaerobic conversion takes place communicates with gasometer 60 by way of pipes 62, 64, the pipe 62 conveying gas and the pipe 64 conveying sludge and liquid. The sediment is removed from the gasometer through pipe 67, the liquid through pipe 66, and the gas through pipe 65. In some cases PH controlling substances, for example, lime may be added to the conversion container. Bacteria nutrients may also be added.

Abstract: 962,538. Moulding hollow fibre articles. H. J. FITZPATRICK. Aug. 30, 1960 [June 5, 1959], No. 19241/59. Heading B5A. [Also in Divisions B8 and E1] Apparatus for making moulded articles with long tubular voids, e.g. tubes, receptacles and hollow panels from fibrous pump or cement slurry, comprises a plurality of long tubular core moulds 18 having side wall moulding surfaces on which material may be deposited by suction, a frame 10, means for detachably mounting each mould in the frame in spaced relation to another mould and means to actuate the moulds when mounted in the frame from a normal position in which moulding material may be deposited on their respective moulding surfaces, to an integrating position, in which the moulding surfaces are in closer spaced relation, to integrate the moulding material deposited on the moulding surfaces. The mounting means for each mould consists of cross-pieces 19, 21, 23, the mould being detachably mounted in holders 28 on carriages 24 slidable on the crosspieces 19, 21 and located by stops 33 and hinged bars 40, 42. Holes in the tops of the carriages 24 and in the bottoms of the moulds 18 communicate, the join being made watertight by rubber grommets so that suction may be applied to the moulds at 30, Fig. 1. Side face moulds 17 and upper and lower face moulds 20, 22 are also supported in the frame 10 but moulding material may be deposited only on the one inwardly facing side of these moulds. The moulds are held in spaced relation as shown in Fig. 1, the whole frame is submerged in a bath of the desired slurry and a deposit of the moulding material formed on each of the mould faces by suction. With the frame in the slurry and with the suction still applied, the side face moulds 17 are moved inwardly by air cylinders 44 acting on pivoted levers 46, to the position shown in Fig. 6 where the deposits formed on the separate moulds have become integrated. The upper and lower face moulds 20, 22 are then moved downwardly and upwardly by air cylinders 54, 60 respectively to complete the moulded article. After removal from the slurry the outer moulds may be retracted and the core moulds 18 removed in staggered time relation. The removal of the core moulds may be assisted by the action of compressed air applied to these moulds while the outer face moulds are still in position, or the core moulds may be covered with limp pervious liners of textile fabric so that after formation of the article the moulds may be slid out of position from inside the liners and the liners may then be peeled from the article. Metal or fabric reinforcement may be provided in the moulded articles by interposition between the separate mould deposits before their integration. Specification 962,539 is referred to.

Title: Improvements in or relating to travelling wave tubes
Inventor: SWIFT-HOOK DONALD THOMAS
IPC: H01J23/24
Filed: 1959-06-05
Abstract: 883,871. Travelling wave tubes. M-O VALVE CO Ltd. Aug. 31, 1960 [June 5, 1959], No. 19397/59. Class 39(1) In a travelling wave tube preferably a backward wave oscillator having an interdigital delay line and operating with crossed electric and magnetic fields the teeth of the combs are arranged so that a portion of each tooth adjacent the free end of the tooth is shielded from electron bombardment by a portion of the immediately adjacent upstream tooth, the latter portion being remote from the free end of that tooth. This is achieved by cutting a rectangular slice off each tooth from a part half way across channel member 2 with which the combs are integral to the free end of each tooth. About # of the width of each tooth is removed. Alternatively the teeth may be tapered along their length. A coating of resistive material is disposed on some of the teeth at the collector end.

Abstract: 646,254. Automatic circuit - breakers. GENERAL ELECTRIC CO., Ltd., and BRYER, R. F. July 21, 1948, No. 19542. [Class 38(v)] A contactor, specially adaptec for accurately timing X-ray exposures and for causing A.C. cur rent to be broker say, just before the zero of the cycle comprises a contact member 6 locked t( an armature 3 so that both move to gether about a pivot 4 when a coil 2 is energized to cause the closing oi contacts 7, 13, the members 3, 6 being later unlocked sc that member 6 car move rapidly to the open position at a predeterminec point in the A.C. cycle. The locking is effected by a lever 11 which passes through an aperture in the channel-shaped member 6 and is itself slotted so as to engage the member 6 under the influence of a spring 12. To bring about unlocking, a magnet 25 is de-energized so that a stop 28 brings a lever 22 into the position shown in which a projection 26 is engageable by a toothed wheel 27 driven by a synchronous motor so that the time taken for the wheel to move the distance of one tooth is equal to half a cycle. The moment of the A.C. cycle at which unlocking occurs thus depends on the setting of the wheel 27 relative to the motor winding. As the lever 22 is driven downwards by the wheel 27, it is eventually itself locked by the stop 28 engaging a slot. Subsequent de-energizing of magnet 1 and energization of magnet 25 causes declutching of parts 26, 27 and relocking of parts 3, 6.

Title: A method and apparatus for packing materials
IPC: B65B63/02
Filed: 1928-07-06
Abstract: 320,116. Gibson, C. Carew-, and Holmes, W. July 6, 1928. Packeting compressible materials in tins.-In a machine for packeting compressible materials, such as tobacco, the tins 2, Fig. 2, are fed from a disc 1 by a belt 4 into pockets 7 in a spider 6. Each pocket is arranged immediately below a compression chamber 13 on a rotary table 9 moving in synchronism with the spider 6. The upper portion of the compression chamber comprises a part 18, Figs. 2 and 3, fixed to the table 9, and radially movable walls 17. When a charge of tobacco is introduced through a feed shoot into the upper portion of the compression chamber, the wall 17 is retracted as shown in Fig. 2, and, on moving to the next station of rest, a fixed guide cam 23 forces the wall into the position shown in Fig. 3, effecting a preliminary compression. The upper edges of the chamber are flared outwards at. 16 so as to facilitate the introduction of the charge. Each wall 17 is connected by a link 20 to the one opposite, so that when compression takes place, the empty chamber opposite is expanded for the next cycle of operations. The bottom of the chamber 13 arrives over a fixed plate 15 and a. plunger 29 descends and compresses the charge into the chamber 13. At the next pause, a plunger 30 pushes the compressed charge out of the chamber 13 into the tin 2, the plate 15 having terminals between the points of operation of the plungers 29, 30. At the next stage, the tins are ejected from the machine on to a conveyer. The plungers may be of the metal known under the registered Trade Mark " Monel," and may be heated by electric or other means. Pads may be placed so as to clean the plungers. In another method of operation, the tin-feeding mechanism may be dispensed with and the compressed tobacco fed on to a belt ready to be placed in tins by hand.

Title: Improvements in clutch operating devices for motor vehicles
IPC: B60K23/02
Filed: 1931-07-09
Abstract: 382,294. Controlling motor vehicles. CURRY, R. J., of Spillman Engineering Corporation, Goundry Street, Tonawanda, New York, U.S.A. July 9, 1931, No. 19736. [Class 79 (v).] In clutch control means of the type wherein the clutch pedal is automatically operated in accordance with movements of the throttle by a piston in a cylinder communicating through a valve with the intake manifold, the cylinder or equivalent is angularly adjustable about its longitudinal axis and the valve means is angularly adjustable about an axis substantially normal to the cylinder axis, thereby facilitating adaptation to various types of vehicles. The connection between the piston and clutch levers may be adjustable and the piston stroke may be adjustably limited. The throttle may also be operated without operating the clutch pedal or lever. The accelerator lever 23, 22 acts upon the throttle 19 through a link 21. The clutch lever 15 is provided with an adjustable extension 42 connected to the piston-rod 38, its end being formed with a rounded aperture and pressed upwards by a spring 43 against an adjustable nut 41. The piston operates in a cylinder 30 adjustably secured by nuts to a stem 33 pivoted to a vertical floor-bolt 36a. The cylinder communicates with the intake manifold 12 through a flexible conduit 54 so that when subjected to the suction thereof the piston is drawn down taking the clutch out of engagement. The action is controlled by a valve 55, Fig. 4, pressed open against a spring 58 by a bell crank 59, 64, Fig. 2, operated through a wire or link 66 by the throttle control link 21, an adjustable stop 67 on the throttle link engaging a block 68 on the wire. To release the piston, air is admitted to the cylinder through a venting valve, Fig. 5, comprising a steeplythreaded plug 73, the upper end of which is castellated &c. to receive an operating arm 78 in various positions, the arm being connected by a wire or link 82 to a second stop 83 on the link 21 operating between blocks 84. The valve 73 is opened as the valve 55 is closed, this action taking place when the accelerator pedal is depressed, thereby allowing engagement of the clutch. The yielding nature of the flexible connection 66 enables the bell crank 59, 64 to be positively held out of action when desired by means of a Bowden control 86, 87, leading from a plug 88 on the instrument board, the throttle then being operable without affecting the clutch. The valve means 55, 73 are both carried by a block 46, screwed into the side of the cylinder, the Bowden casing being clamped in a bifurcated arm 85 on the block.

In a laundry ironing machine in which articles are fed to the machine in succession by one or more operators, means G is operated by the passage of the articles, for controlliug the operation of a clock device so that the device is rendered operative only either when no article is passing a given point or when an article is passing the point. The means G consists of an electric contact which is insulated from the frame of the machine and which is raised out of contact with a metal plate E when articles are fed from the delivery side of a machine of the type having a plurality of rollers each rotating in a concave bed. A plurality of contacts, one for each operator and a similar number of clocks J<SP>1</SP>,J<SP>5</SP> may be provided. Each contact G is mounted by means of an insulated bush on a bar F and each is either connected in series with a clock and with an electric supply so that the clock runs when the contact between G and the plate E is made or a relay is used in the circuit so that the clock runs when contact is not made, hence the clock indicates the time during a given period, which may be recorded by a clock J arranged to run continuously for the period, when the machine is not effectively used or the reverse by the particular operator. A photo-electric cell may be used instead of a movable contact.
