Title: Improvements in duct systems for combustible mixtures
IPC: F16K17/16
Filed: 1959-02-10
Abstract: 872,063. Pressure-relieving devices for fluids. RASBASH, D. J., and ROGOWSKI, Z. W. April 4, 1960 [Feb. 10, 1959], No. 4564/59. Class 135. [Also in Group XXVIII] In a duct for conveying combustible gases or vapours vents consisting of a series of elongated slits 11c, Fig. 2C, or relatively closelyspaced holes 11b, Fig. 2B, are formed at short intervals along the length of the duct, the vent area per unit length of duct being such as to permit the escape of burnt gas behind a flame front in the duct at a rate sufficient to retard the flame front to a velocity less than a predetermined safe maximum at any cross-section of the duct. Each vent is closed by a device responsive to abnormal conditions of temperature and/or pressure in the duct for opening the vent under such conditions. As shown, the vents are arranged in a line parallel to the axis of the duct along at least one side thereof or in a helix when the duct has a circular section. The closure device consists of a plate 23, Fig. 9, of non-magnetic material having a ferromagnetic armature 26 embedded therein which co-operates with magnets 22, Fig. 7, arranged along each side of the vent 20 in the duct, the vent being surrounded by a gasket 21. Alternatively, the plate is of metal and is retained by frictional, gravity or spring means or by a mechanism operated by a detector responsive to the abnormal conditions in the duct. Alternatively again, the vent is sealed by a frangible diaphragm which may be made of a material, e.g. polyethylene, having a low latent heat of fusion and which melts or burns under flame conditions in the duct, or which may be broken by external means under the control of a flame detector.

IPC: C09D163/00
Filed: 1964-02-03
Abstract: Particles of a polyolefin are coated with an uncured epoxy resin. The coating may contain a curing agent, chosen so that the resin is stable for several hours at room temperature but cures rapidly at 150 DEG C. or above.  The preferred polyolefin is polyethylene, with a melt flow index between 10 and 30 and a particle size between 30 and 400 B.S.S.  The particles, resin, curing agent and an inert volatile solvent may be mixed, and the solvent subsequently evaporated. Coating processes.  The coated particles may be used to coat metals such as brass, iron, steel, aluminium or copper by spraying (including flame spraying and electrostatic spraying) or by the fluidized bed process.  The metal may first be degreased and shot-blasted and is preferably pre-heated.  The metal may also be heated after coating to cure the resin.  Metal plates and the insides of metal containers may be so coated.

Abstract: 377,912. Corrugating sheets ; making radiators. ERIKSSON, E. E., Degerfors, Sweden. Feb. 24, 1932, No. 5529. Convention date, March 13, 1931. [Classes 83 (ii) and 83 (iv).] In making dovetail or like corrugations in metal sheets, the sheet is first formed with upright corrugations and is then inserted in a die outlined in conformity with the troughs but having a free space below the top of the crests and the crests are pressed down against the die and counter-members, the outlines of which correspond to the desired outlines of the troughs. The previously corrugated sheet 2 is placed in a die 1 with the crests 4 spaced from the top of the projections 3. The upper die 7, the face 8 of which presses the crests against the top of the projections, carries countermembers consisting of bars 9, which are normally held together by springs 17. On the downward movement of the die 7, prior to the pressing operation, the bars are pressed outwards so as to fill the lower parts of the troughs by shouldered wedge-members 10 which are normally projected by springs 13 from the face of the die. During the subsequent pressing operation in which the sides of the crests are pressed against bevelled surfaces of the bars 9, the springs 13 prevent displacement of the sheet. The wedge-members are provided at their ends with flanges 11 engaging shoulders 12 on the bars so as to raise them from the troughs after the springs 17 have drawn the bars together during the upward movement of the die 7. The wedge members are slotted at intervals so as to pass over the springs 17. The projections 3 and the surfaces 8 may be plane or shaped surfaces. The collapsable countermembers may be replaced by fixed members inserted and removed longitudinally of the corrugations. The corrugations may be dovetailed simultaneously or one by one. A sheet may also be produced in which a part only thereof is corrugated or in which only a number of the corrugations are dovetailed ; thus in making corrugated sheets for heating radiators the sheets may be provided with one or more strips only of dovetailed corrugations, these being utilized for subsequently holding the sheets together.
