Title: Process and apparatus for the production of combustible gas
IPC: C01B3/46
Filed: 1956-11-09
Abstract: 847,497. Gas manufacture. SOC. DE CONSTRUCTION D'APPAREILS POUR GAZ A L'EAU ET GAZ INDUSTRIELS. Nov. 9, 1956 [Nov. 28, 1955], No. 34365/56. Class 55 (2). In the cyclic production of a combustible gas by the catalytic cracking of liquid or gaseous hydrocarbons, the catalyst is heated by a heatstorage mass which is heated, during plantheating phases, by gases which do not pass through the catalyst, since it may be desirable if low quality fuel is used, to isolate the catalyst from combustion products which may be detrimental thereto. In Fig. 1, catalyst beds 2 are provided in superposed stages each having a regenerative mass consisting of checkerwork 3 and the refractory lining of the stage. Each stage has air and fuel inlets 11, 10, the combustion products passing to an outlet 12 without passing through the catalyst bed 2. The heating-phase is followed by a gas-making phase, during which the valves V 9 , V 10 , V 11'  V 1  2 , V 13  are closed and the valve V 7 , for the gasmaking hydrocarbon, and the valve V 8'  for steam, are opened. The make-gas passes through a water-seal outlet 5. If desired, a phase may be interposed between the plant-heating and gas-making phases, during which air is admitted through the valve V 9  and fuel, which may be different from the fuel previously used for plant heating, passed through the valve V 10'  the combustion products, which give additional heat to the plant, passing to waste through the valve V 13 . In a modification, the air supplied through the valve V 11  is preheated by heat-exchange with the exhausted plant-heating gases. In another modification, Fig. 3, the heat from the plant-heating gases is stored in two series of checkerwork vessels 15 which are used in alternation. During plant-heating by the supply of air and fuel through valves V 11'  V 10  at the left-hand side of the plant, the left-hand valves V 12  being closed, the combustion products pass across the chambers 3, which have no checkerwork, through the regenerator chambers 15 at the right-hand side, the valves V 12  being open and the valves 10, 11 being closed. The heat for the reaction is provided by the hot linings of the chambers 3, and when the next plant-heating phase is effected, the combustion air is heated in the right-hand chambers 15. The superposed stages of the plant shown in Fig. 1 may be heated by combustion products which are generated in the lowest chamber and are passed upwardly from stage to stage through conduits which by-pass the catalyst beds. In another arrangement, a cracking chamber with a single catalyst bed is flanked by two checkerwork chambers which are used in alternation. During the plant-heating phase, one of the checkerwork chambers is heated by combustion, after which oil is sprayed on to the top of the checkerwork and steam is admitted beneath the checkerwork to pass therethrough to mix with the vaporized oil before passing to the catalyst bed and away, through the water seal, for use.

Class 64 (3). In a heat exchanger comprising an air-cooled condenser tube unit and a condensate-cooler tube unit connected in series therewith, the condenser tube units 2a, 2b are arranged in gable fashion at an acute angle to one another with at least one fan 9 mounted at the base plane thereof, above a suction chamber 4, the side walls of which are defined by vertically extending rows of generally horizontal condensate-cooling elements 6a, 6b, the fan or fans being positioned to suck a current of cooling air over the tubes of the condensate cooler and to blow this air over the condenser tubes. In the form shown, steam enters the conduit 1 and flows thence to the elements 2a, 2b from which it is discharged mainly as condensate through conduits 3a, 3b leading to the condensatecooling elements 6a, 6b. Uncondensed gases together with any uncondensed steam pass to reflux condenser units 8a. Cooled condensate is discharged from the lowermost of the elements 6a, 6b through conduits 7a which incorporate a control valve 16, sight glass 17 and a U-bend to maintain the elements 6a, 6b full of condensate. Air is impelled by the fan or fans 9 over elements 6a, 6b and then over elements 2a, 2b and may be cooled en route by water jets 10, 10a, 10b. The fan may be regulated in accordance with the temperature of the cooling air. A servicing platform 12 may incorporate screens 12a to separate the inflowing and outflowing air streams.

[Class 80 (i)] In belt-shifting mechanism, the operator may move the belt slowly from the loose pulley to the fast pulley and quickly from the fast pulley to the loose pulley by the use of two different mechanisms. In the form shown, thebelt 4 is shifted by forks 2 on a slide 3, which may be traversed by a crank 7, operable either directly by a handle 9 or through a reducing gear 11, 10 from a handle 13. The gear 10, 11 allows the handle 13 to rotate idly when the quick-operating stopping-handle 9 is operated. The fast pulley 6, Fig. 3, may be provided with grooves 6a of gradually increasing diameter to facilitate take-up of the drive. The invention is particularly applicable to spinning machinery in which the inertia of the parts driven by the main shaft is considerable. Inching is thus facilitated.
Patent GB-818282-A (GB)
Title: Fabricating method
Inventor: JONES EDWARD RICHARD STANLEY
IPC: C08J5/12
Filed: 1955-12-02
Abstract: Composite articles are produced by coating a surface of a metal shaping with a thin layer of polythene, oxidizing this layer by baking it at a temperature above its melting-point, and contacting the coated metal with a polythene shaping and bonding it thereto by heat, the metal being heated for the bonding step sufficiently to render fluid the adjoining surface of the polythene shaping but not sufficiently to render fluid the body of the polythene shaping.  The initial coating may be applied as described in the parent Specification or by spreading on, or dipping the reinforcement in, a polythene gel.  The method may be applied to the production of polythene gaskets on metal surfaces to be fitted together, e.g. parts of a vehicle body or window frame, and two metal surfaces may be so bonded to opposite sides of a polythene fillet.

This arrangement is said to reduce errors due, in particular, to encrustation of the electrodes. For example if the current electrode 5, Fig. 3, becomes encrusted, thereby moving its effective electrical position, the effect on the parallel pick-up electrodes 7', 7", is not so great as when single electrodes are used.
