Patent GB-1002088-A (GB)
Title: Process for the recovery of chlorine from chlorohydrocarbon residues
IPC: C01B7/00
Filed: 1962-06-20
Abstract: Chlorine is recovered from fully and partially chlorinated chlorohydrocarbon residues by burning the residues with oxygen or a free-oxygen containing gas, e.g. air, O2 enriched air, at elevated temperatures, e.g. 700-1300 DEG  C., and recovering the chlorine from the combustion gases.  The chlorohydrocarbon residues may be supplied as a vapour or liquid atomized by the oxygen for combustion or solid chlorohydrocarbons dissolved in liquid chlorohydrocarbons. The oxygen may be used in an excess, e.g. 2-30 mole per cent.  The chlorohydrocarbons may be hexachloroethane, hexachlorobutadiene, hexachlorobenzene, also chloroethanes, -ethylenes, and -propanes. Suitable reaction-chambers are water-cooled metal furnaces, bricklined furnaces, tubes of ceramics, quartz or vitreous silica ware.  A combustible gas, e.g. H2, may be used to initiate the reaction or re-ignite the reaction flame in the event of its extinction.  This may be done using a combustion nozzle comprising three concentric tubes, e.g. of quartz, the inner one for the chlorohydrocarbon, the middle one for the oxygen and the outer one for the combustible gas.

Title: Stropping and grinding apparatus for razor blades
IPC: B24D15/08
Filed: 1931-08-24
Abstract: 377,466. Sharpening razor blades. DUBSKY, R., 121, Margaretenstrasse. Vienna. Aug. 24,1931, No. 23785. [Class 60.] In a device for stropping double-edged razor blades in which the oscillating holder 3 of the blade 2 is mounted in a frame comprising sideplates 7 connected by a plate 7<1> having a handle 9, the frame may be lifted so far away from the strop 1 that the blade may be turned through 180‹ by means of a knob 10 to strop the reverse side of the blade. The blade-holder is tilted alternately in opposite directions to strop the opposite edges by means of gearing 5, 6 and roller 4 and the strop is guided during operation by guides 8. In a modification, Fig. 5, the guides 8 are pivotally mounted at 11 so that the blade may be stropped diagonally. The blade-holder comprises a lower plate 13 having its ends bent up to form pins 14, 15 which bear in the side-plates, and a depression 16 coacting with a bridge-piece 17 forms a guide for the pivot pin 18 of the upper plate. The upper clamping plate is swung about the pivot 18 the blade placed over projections 20, 20<1> in the lower plate and the upper plate then positioned so that holes therein engage over the projections. To look the blade, the upper plate is moved to the right, Fig. 8, by pressure on the friction surface 24. During this movement the pivot 18 slides along the slot 16 until a tongue 22 engages under the head of one of the projections 20 to lock the plates together.

Title: Picture treatment process
IPC: B29C63/00
Filed: 1974-05-15
Abstract: 1470758 Coating pictures MULLIONAIRES Ltd 15 May 1974 [18 May 1973] 23842/73 Heading B2E [Also in Division B6] Pictures such as paintings, drawings, maps, prints or photographs are provided with a protective coating by applying a clear hardenable synthetic resin in liquid state to the picture surface adjacent to one edge thereof, spreading the resin evenly over the picture surface by pressing a flexible spreader sheet over the surface progressively from said edge, the contacting surface of the sheet having been treated so as not to adhere to the resin, allowing or causing the resin to harden, and removing the spreader sheet to leave a clear protective layer of resin on the picture surface. The picture 1 is mounted by glueing onto a rigid backing board 2 of hardboard, blockboard, chipboard or wood and the mounted picture then placed on a horizontal base 3 with one end of the board abutting an upstanding stop 4. The picture may be then given an initial thin brushed coating of polyester resin to seal it, the resin being allowed to set before applying the protective layer of the invention. A rectangular frame 5 is hinged at one edge of the base 3 about an axis parallel to the picture edge, and carries a flexible spreader sheet 6 of plastics film. The end of the base 3 has a clamp 10 for releasably securing the frame 5 in a position where the spreader sheet 6 is parallel to and slightly spaced from the picture surface. A release agent is applied to the lower face of the film, the frame being in a raised position away from the picture. A clear synthetic resin 11 is applied to the face of the picture across its entire width adjacent to the end adjoining the hinged end of the frame. The frame is then lowered into contact with the resin, and a soft roller 12 is advanced over the upper surface of the sheet in the direction shown in the Figure to spread the resin progressively across the picture surface. Finally the frame is clamped in the lowered position and left thus until the resin has hardened. After hardening the frame is released and raised to part the spreader sheet from the layer of resin to leave a clear smooth protective film of resin on the picture surface.

Filed: 1966-06-01
Abstract: Trowel means for smoothing a layer of plastic lining material in an interior generally cylindrical surface comprises a plurality of longitudinally extending plate members 20 which combine to form a generally frustoconical trowel body having a small leading end and a resiliently expansible larger trailing end, the portions 21 of the plate members adjacent the small end being substantially flat and the remaining portions being arcuate in transverse cross section and of progressively increasing radius toward the large end with such arcuate portions in laterally overlapping relation to form said frusto-conical body, and a central mounting member 23 at the small end of said trowel body, the flat portions of plate members 20 being fixed against mounting surfaces on member 23 permitting flexure of the plate members 20 about transverse axes whereby the diameter of the large end of the trowel body may readily expand and contract by relative intersliding movement of said overlapping arcuate portions. Resilient means may be provided within the larger end of the trowel body to exert a perimeter-increasing force for resiliently urging the plate members radially outwardly to urge said larger end into yieldable troweling contact with the lining material or alternatively the plate members may have qualities of resilience and the free diameter of the larger end of the trowel body may be substantially greater than the troweling diameter such that when drawn through a cylindrical member the larger diameter portions of the plate members press yieldingly against the lining material surface to be troweled. The mounting member 23 is preferably polygonal in shape the number of flat outer surfaces corresponding to the number of plate members 20 employed and the flat portions of the plate members 20 being fixed against the flat surfaces of the polygonal mounting member.  In use the trowel means is drawn along behind a lining machine 10 which applies lining material to the interior surface of pipe 11 by a rotary distributor head 13.
