Patent GB-586768-A (GB)
Title: The coating of surfaces with polythene compositions
IPC: B05D7/26
Filed: 1944-09-01
Abstract: Polythene compositions are bonded to surfaces by cementing to the surfaces a layer of asbestos, of such thickness that the cement does not penetrate through it, and thereafter covering the asbestos with polythene composition; or by cementing to the surfaces a layer of asbestos the uncemented surface of which has been coated previously with polythene composition; or by mixing the polythene composition, in a finely divided state, with asbestos, attaching the mixture to the surface with an asbestos cement and after the cement has set, subjecting the mixture to heat and pressure, e.g., with a heated roller, until a layer of polythene has been formed over the surface. The polythene composition may be applied in the fused state or dissolved in a solvent, e.g., a hydrocarbon or chlorinated hydrocarbon which is afterwards evaporated at temperatures greater than 60 DEG C.  In the former method, a flame gun is preferably used as described in Specification 551,339; or in the case of metal tubes as described in Specification 585,395.  Alternatively the polythene may be applied by dispersing it in a solution of one or more normally solid film-forming materials in a volatile liquid.  Other layers may be applied, e.g., asbestos may be fused on to the polythene and tiles may then be cemented on to the asbestos.  Specification 432,831, [Group II], also is referred to.

Abstract: 1,098,240. Wrapping-machines. LAMBGRAYS HARBOR CO. Inc. April 19, 1966, No. 17105/66. Heading B8C. In an apparatus for enclosing a roll of paper R in a wrapper means 19, 20 seal end core plugs into the roll and a conveyer 24 feeds the roll adjacent a wrapping table 25 along which the wrapper is fed from a dispenser 26 at the same speed, the roll being discharged across the table by a kicker bar 45 and picking up the wrapper which is rolled thereabout, after which the wrapped roll is fed to a pair of end crimpers 54, 59 with associated means 56, 60 for applying end labels. The rolls are fed by conveyers 10, 12 to an operator who manually inserts the core plugs and positions the roll on a bed 16 opposite a piston head 19<SP>1</SP> which extends to push the roll against a stop 20 and the plugs into the core. A switch 22 on the stop 20 is energized by the pressure of the roll to cause the piston head 19<SP>1</SP> to retract. The bed 16 is then tilted so that the roll R moves on to the conveyer 24. The conveyer 24 feeds the roll in the direction of its axis past a switch arm (40a), Fig. 6 (not shown), causing the wrapper (27x), Fig. 5 (not shown), to be fed on to the table 25 by feed rollers (42), (42<SP>1</SP>) at the same speed as that of the conveyer 24 until the switch (40a) is released by the roll to stop the feed rollers. The wrapper is gripped and forwarded by belts 29 having suction apertures 38. Release of the stop (40a) also activates means rotating a blade (45), Fig. 5 (not shown), coacting with a blade (44) to cut the wrapper. A pair of glue dispensers (47) are activated by the roll R abutting a switch 39 and discharge longitudinal strips (9) of adhesive on to the wrapper. The conveyer 24 is stopped when the roll releases a switch 41 also energizing the bar 45 which pushes the roll over the wrapper. The roll R adheres to the near glued edge of the wrapper and rolls the wrapper around itself until the other glued edge adheres to the roll. The roll abuts a hinged stop (51), Fig. 2 (not shown), which subsequently releases it for rolling past the crimping and labelling means (not detailed).

Filed: 1940-12-03
Abstract: 578,872. Gas-purifying processes. EGERTON, A. C. G. Dec. 3, 1940, No. 17185. [Class 55 (ii)] [Also in Group XXVIII] Gases containing sulphur compounds, or unsaturated hydrocarbons, or both, are purified by being subjected to cooling by liquid methane. The cooling may be effected by bringing the cooling medium into direct contact with the gases, or indirectly by passage of the gases through a coil immersed in the liquefied methane. Where the gases contain hydrogen sulphide, water vapour, or carbon dioxide, the prior removal of these constituents is desirable. The process is applicable to the purification of mixed gases such as water gas and coal gas employed in the synthesis of methane. A plurality of coolers in series may be used, the first acting as a pre-cooler or a heat exchanger through which the gases to be treated are passed in indirect contact with the gaseous methane arising from evaporation of the liquid methane.

Title: Method of and apparatus for the production of shell moulds
IPC: B22C23/00
Filed: 1953-06-22
Abstract: 737,143. Moulding-machines. DEUTSCHE EDELSTAHLWERKE AKT.-GES. June 22, 1953 [June 30, 1952], No. 17300/53. Class 83 (1). In a shell-moulding process, patterns preheated by travelling through an oven are successively brought into operative engagement with at least one pressure head, to which moulding material is delivered by compressed air and discharged to the pattern and the excess material is removed by tipping the pattern relatively to the pressure head. Patterns 4 are moved through an oven 1 by a turnstile 2 to the discharge opening 3 where a parting-medium is applied and an intermediate frame 5 fitted. The frame is connected to the piston-rod of a cylinder 6 operable to position the frame and pattern beneath pressure heads 9, which are then lowered and the sand-resin mix blown onto the pattern by low-pressure compressed air. After blowing, the pressure heads are raised and the pattern rotated through 360 degrees by a turnover mechanism 10, surplus mix falling on to a shoot 11 and returning to a pressure-container 15. The pattern is then moved back through the oven to cure the mould. The pressure heads and conduits conveying the mix are preferably made of an elastic material such as rubber. In a modification, Figs. 3 and 4, a fully automatic machine comprises a circular oven 18 through which are moved patterns on arms 20 and which has a segmental recess 22 in which are three stations. At the first station 23 a pattern plate is rotated through 180 degrees and a previously-formed and cured mould ejected by ejector pins in the pattern actuated by a press 24, the mould falling on to a conveyer 25, preferably of rubber. Still in the inverted position the pattern moves to the second station 26 over a suction device which removes adhering material. The pattern is then coated with a parting medium, and rotated back through 180 degrees as it travels to the third station 29, where pressure heads 30 and a frame 31 are positioned on the pattern. Valves in the pressure containers 33 and the supply from a collecting hopper 34 are thereby actuated and the mix blown. The pressure heads are raised, the pattern rocked to return excess mix to the containers 33, the frame 31 lifted by a linkage 36 and the pattern-plate and adhering mould moved through the oven for curing. The apparatus is controlled by mechanical and electrical devices, or hydraulic or pneumatic devices.

Each device 2 extends the height of the vehicle, and half the width, and may be suspended from a runner 3. In Fig. 2 the wall of the chamber of the device is a length of rubber tube 17 closed up into a rectangular shape, glued between the panels and filled with air at atmospheric or slightly higher pressure. On compression of the device the air enclosed by the tube and the panels escapes through an orifice 8, and the air inside the tube is compressed and moves the panels apart after impact has ceased. In Fig. 3 the wall is a strip of latex foam in a rectangular shape held by precompression between the panels by ties 28, or by glueing. The foam may be open-cell, in which case the cells constitute the communication to atmosphere, or closed-cell, in which case the communication is via an orifice formed in the foam or the panels. In Fig. 4, the wall is a tube 30 with two closed ends 31, 32 formed into a discontinuous rectangle. The tube 30 is covered with a laced-up fabric bag 35, the gap 33 between the tube ends, and the gaps between the lacings 36 providing the communication to atmosphere. The tube 30 is pumped up to separate the panels by a hand-pump 41, or exhausted when not in use, tension spring (45, 50, Figs. 5, 7, not shown) or rubber bands (51, Fig. 8, not shown) pulling the panels together. Instead of the tube ends abutting, they may overlap each other (Fig. 6, not shown) or the tube may be closed like the tube 17.
