Abstract: 830,966. Cutting by fusion. HANCOCK & CO. (ENGINEERS) Ltd. May 4, 1956 [Feb. 8, 1955], No. 3759/55. Class 83 (4). A flame-cutting burner head, particularly for preparing the edges of plates prior to welding, comprises a burner 1, Fig. 1, arranged to cut a lower bevel in the edge of the plate and a burner 3 arranged to cut an upper bevel in said edge, each of the two burners being carried by an individual mounting 17 and being supported above the plate by a height control wheel 24, 20 running on the surface of the plate and causing its associated burner to rise and fall in conformity with said surface, each burner being biased by a spring arranged to urge the burner upwardly whereby the wheel is relieved of the bulk of the weight of the vertically moving parts. The burner head also carries a third burner 2 arranged to cut a vertical root between the two bevels. The burners 1, 2, 3 are arranged in that sequence in the direction of cutting. The burners 1 and 3 are clamped in burner holders 11 on which protractor scales 19 are provided for setting the angle of the burners. Burner 2 is supported vertically in its holder 11. Each holder 11, Fig. 6, is mounted on the lower end of a tube 10 fixed within a block 7 running on rollers 8 along vertical guides 4 in a casing 17; the guides 4 are preferably of circular cross-section, Fig. 8 (not shown). Above the casing 17 is a fixed vertical tube 15 providing a fixed anchoring point 13 for a tension spring 14 secured at 12 to the lower end of the tube 10. A collar 31 on the upper end of tube 10 is adapted to engage an adjustable tube 32 for limiting the downward movement of the burner. Vertical adjustment of tube 32 is effected by a screw 34 and a spring 33 is provided between block 7 and tube 32. The supports 17 for the bevel cutting burners 1, 3 have stub shafts 16 mounted in slide members 35, Fig. 2 (not shown) slidable in a horizontal slideway 36a, Fig. 1, by means of lead screws 37. The support for burner 2 is also adjustably mounted on the slideway 36a. Burner 3 has its individual wheel 20 vertically adjustable in the holder 11 by a screw 23. A single wheel 24 may be used for both burners 1, 2. This wheel may be mounted for vertical adjustment in the holder of burner 2 which carries an arm 25 supporting a finger screw 29 whose upper end bears against a bar 30 secured to the holder of burner 1. Rotation of screw 29 therefore adjusts the height of burner 1. Alternatively the wheel 24 may be carried by the holder of burner 1 and used to control the height of both burners 1, 2 or the burners 1, 2 may have individual height control wheels. The slideway 36a is supported on a profiling machine able to execute cuts in both longitudinal and transverse directions whereby the four edges of a plate may be cut successively by swinging the cutting head into four successive positions. Control valves 41 for heating oxygen, fuel gas, and cutting oxygen are supported on a vertical post 38 extending above the slideway 36a.

Title: Method for chlorine recovery
Inventor: HOOKER THOMAS
IPC: C01B7/00
Filed: 1956-02-09
Abstract: <PICT:0798576/III/1> Chlorine gas is separated from gas mixtures of chlorine and carbon dioxide by passing the mixture into contact with water between 10 DEG  and 100 DEG  C. and maintaining the pressure of the carbon dioxide in the absorption system below 1.5 atmospheres absolute; absorbing into water at a super-atmospheric pressure the chlorine gas; withdrawing said water from the absorption system and desorbing the chlorine used from the chlorine-water solution by reducing the pressure thereon.  The chlorine-water solution which has been desorbed by flashing may be recycled to the chlorine absorption system.  The method which is particularly useful in the recovery of chlorine gases from chlorine-liquefier vent gases produced in commercial electrolytic chlor-alkali plants is illustrated by the flow sheet shown in the Figure.  Gases are exhausted from a chlorine drying compression and liquefaction system 1 and introduced into a packed absorption tower 4 which is maintained at a pressure equal to or slightly less than the pressure of system 1, the chlorine in the vent gases is absorbed by the water, and the carbon monoxide and other non-absorbed gases which may be contained in the gas mixture are lead to the outlet line 8; the water, substantially saturated with chlorine gas, passes out of the absorption tower 4 and into the direct contact cooler section 9.  This tower has a lower steam-stripping section 13 which in this embodiment comprises two superposed communicating sections 9 and 13, however these may be separated.  The cell gases leave the tower through line 12 while the water after stream stripping leaves through line 16 and may be re-cycled.

Title: Attachment of detergent material to synthetic sponge
IPC: A47L13/16
Filed: 1962-02-02
Abstract: <PICT:0977156/C4-C5/1> <PICT:0977156/C4-C5/2> A composite synthetic sponge and detergent tablet comprises a water-impermeable barrier held by one face to the detergent tablet by means of a water-insoluble pressure-sensitive adhesive, the other face being held by means of a water-insoluble pressure-sensitive adhesive to a synthetic sponge.  Suitable anionic detergents are soap, alkyl sulphates, fatty acid monoglyceride sulphates, sulphated alkanolamides or fatty alcohol/ethylene oxide condensates, alkyl or alkylarly sulphonates, N-fatty acyl taurides or sarcosides, sulphoacetates, the cations present being potassium or triethanolamine, but preferably sodium; suitable non-ionic detergents are ethylene oxide condensates with fatty acids or with dialkylphenols, ethylene oxide-propylene oxide block copolymers, and fatty esters of sugars or polyglycols.  The barrier film may consist of natural or synthetic rubber, polyamide, polyester, polyvinyl chloride, and vinyl chloride-vinylidene chloride copolymers, but poly (ethylene terephthalate) is preferred. Poly-ethylene and -propylene and cellulose acetate and acetate-butyrate may also be used but are not recommended.  The adhesive, which should be flexible and resilient, may be a natural or synthetic rubber, silicone elastomer, polyethylene, polyvinyl acetate, polyvinyl butyral, poly (vinyl n-butyl ether), epoxy resin, protein based glue, melamine-, phenol- and urea-formaldehyde resins, and polyamides, but a solution of nitrile rubber is preferred. Suitable sponge material comprises natural or synthetic rubber, polyethylene, polyester, polyvinyl chloride and acetate, but especially polyurethane of the polyester or polyether types. As shown in Fig. 3 a tablet of detergent 33 having sponge material 35 seated in recess 75 and separated from the detergent material by barrier film 37 may be produced (see Fig. 1) by cutting the continuous bar 11 from plodder 13 into bars 19, pressing the bars in rotating spider 21 to produce a depression 75 in one face and passing the pressed bars to unit 39.  Meanwhile sponge strip 45 is coated with adhesive through feeder 47, barrier film 51 is superimposed, further adhesive is applied by feeder 53, and a further layer of backing paper 57 then applied.  Cutter 59 then cuts through all layers except the paper, and stripper 61 removes unrequired pieces of material before the strip of sponges on the backing sheet pass to unit 39.  In this unit the backing 57 is stripped from the sponge laminate and the fresh adhesive face is pressed against recess 75 in the tablets.  The composite detergent block and sponge is then further pressed in press 73 and wrapped in 65, the wrapping material and also the cartons in which the wrapped bars are packed also serve to compress the detergent block and sponge together, thereby improving the bond.
