Title: Improvements in collapsible enclosures, particularly collapsible caravans
IPC: B60P3/34
Filed: 1953-09-24
Abstract: 744,650. Collapsible caravans. PROPERT, T. G. Sept. 24, 1953 [Oct. 2, 1952], No. 26343/53. Class 108 (1). [Also in Groups X, XXX, XXXI and XXXIII] A collapsible caravan comprises a front section 17, Figs. 1, 3, transversely hinged at 67 to telescope over a rear part 18 similarly hinged at 67A, the hinges being mounted on a floor 10 supported on bearers 19, 20, which are in turn mounted on a chassis 21. The floor 10 forms part of an inner section comprising side walls 11, 12, and the bearers 19, 20 may be mounted on channels 29, Fig. 5, slidable in channels 27 so that the caravan body may move rearwardly with respect to the chassis to give access to the towing vehicle boot. This rearward movement of the body may be effected by rotating a screw 31 mounted in a bearing 32 on a cross-member 33 attached to the bearers 19, 20, the other end of the screw engaging a threaded sleeve attached to the chassis. In another embodiment the body underframe may be connected to the chassis for relative movement thereto by spaced parallel links in parallel ruler fashion. The section 17 is provided with a plate 68 which, when the body is extended, provides a continuation of the floor 10. If the body is not slidable, the tow-bar may be made adjustable in length. The sections 17 and 18 may be opened independently, but are preferably coupled by pins 77 engaging slots 78 so that movement of one part causes movement of the other. To facilitate sliding of the walls of the sections past each other, balls mounted in cups are positioned between them. In the closed position the sections 17 and 18 may rest on a sponge rubber strip secured to the bearers 19, 20 and in the extended position flexible strips may be secured along the edges 64 and the top edge of the section 17 to make the body water-tight. Means for displacing the sections to open position may comprise tension or compression springs between the sections, or recessed handles may be provided for manual opening. Means for simultaneously opening and moving the sections rearwardly comprise extension of the hinge pins 67 into horizontal slots in side plates on the chassis, a link being connected on each side rearwardly to the chassis and forwardly to the part 17 near its edge 64. In the closed position the pin extensions are near the front ends of the slots and the links and the edges 64, 73 are in line with the slots, but as the sections move apart the pins move rearwardly along the slots as the links rotate. In a modification, hydraulic means, reduction gearing, or screw jacks may be used, or tension springs may be employed beneath the caravan. One or both sections 17, 18 may have their walls and roof made of glass or wire mesh and so on.

Abstract: 159,917. Illingworth, W. H. Oct. 28, 1919. Mercury cut-outs; fuse-boards.-A non-fusible cut-out of the liquid-thread type comprises a refractive insulating container A having a passage through it restricted at the part a and carrying thimbles B, B' at each end to accommodate the contacts, the upper thimble having a vent-hole b<2> and carrying a detachable plunger D whereby the mercury thread may be restored 'in the container when on overload, it has been expelled in the form of a globule into a cup at the top of the passage. The upper contact C is a metal cup with an external projection c<1> for the lead and a downwardly-projecting tube c; the lower contact is a metal plug C' with a semicircular formation c<5> at the external end for facilitating connection to a bus-bar by means of the clamping-plate c', and a reduced internal part c<4> which may be serrated to increase the surface contact with the mercury. The external sleeve portion of the plunger D carries a washer d which, when the head e<2> is depressed, passes beyond the vent b<2>, against the action of the spring d<3>, and the bevelled edge of the sleeve abuts against the shoulder b<5>. Further pressure depresses the plunger proper E against the action of the spring e<1> into the cup C and restores the thread. In the form shown, two metal thimbles are employed, but these may be replaced by a single moulded insulating casing. The cut-out may be enclosed by back and front insulating-holders F', F, Fig. 6, with recesses to accommodate the busbar and a number of the units may be assembled as a fuse-board as shown in Fig. 4, the leads being led along recesses at the back formed by cut-away parts of the back-holder F<1> and along channels in the holder to the contact. The amperage of the fuse may be increased by arranging a number of mercury threads in parallel as described in Specifications 121,305 and 138,439.

[Class 82 (i)] A cyclic process for obtaining magnesium from its ores, such as magnesite, dolomite &c. comprises treating the ore with hydrofluoric acid, heating the resulting magnesium fluoride with a reducing agent in a non-oxidizing atmosphere at a temperature between the melting point of magnesium fluoride and 1260‹C. condensing the magnesium vapours, treating the fluorinated residue to regenerate hydrofluoric acid, and so on. The reducing agent may be calcium, or a tetravalent element such as silicon, or a compound or alloy of a tetravalent element such as calcium carbide, a calciumsilicon alloy, an iron-silicon alloy, or an ironsilicon-aluminium alloy. The magnesium fluoride to be reduced may be mixed with calcium fluoride, with or without magnesium carbonate. magnesium oxide, or calcium carbonate, or with an alkali-metal fluoride to lower the reaction temperature. Hydrofluoric acid may be supplied to the cycle to make up losses. Metals to be alloyed with magnesium may be introduced into the cycle as metals, ores, or compounds such as fluorides, or added in molten form to the magnesium at the condensation phase ; or if silicon is used as the reducing agent, a magnesium-silicon alloy may be formed and removed from the cycle before the distillation phase. The production of alloys of magnesium with the following metals and pairs of metals is referred to : lithium, cobalt, zirconium, cadmium, lead, aluminium, tin, silver-aluminium, silver-cadmium, silver-copper, silver-antimony, silvertin, aluminium-beryllium, aluminium-copper, aluminium-tin, aluminium-zinc, copper-beryllium, cadmium-antimony, cadmium-tin, cadmium-zinc, copper-antimony, copper-tin, copperzinc, iron-zinc, lithium-tin, lithium-zinc, antimony-tin, antimony-zinc, tin-zinc.

Title: Improvements in methods of bending pipes
IPC: B21D7/14
Filed: 1931-09-24
Abstract: 379,878. Bending pipes. KOSSOWSKI, W., 4, Pieknastrasse, Warsaw. Sept. 24, 1931, No. 26646. [Class 83 (iv).] In bending pipes a device such as a flexible element is secured to the pipe so as to displace the neutral axis of the pipe to a position between the element and the outer wall of the pipe bend so that the whole of the pipe is subjected to compressive stresses. A steel rope s is secured tightly to the tube R between clamps d and loosely carries a number of supports u. The pipe, which is clamped between the bolts b, is now zonally heated by a gas burner &c. at the position 1 and is bent by a force applied at p. Succeeding zones are then treated in the same way. The zones are thus compressed and produce folds round the pipe which are fairly flat at the convex wall of the curve. If, during bending, the rope is released slightly after each operation, the folds on the convex wall are replaced by slight thickenings as shown in Fig. 4. The transverse pressure on the wall of the pipe is taken up by the supports u on each side of the apex of the bending angle.
