Title: Improved method and apparatus for the continuous spinning of textile fibres
IPC: D01D10/04
Filed: 1952-10-17
Abstract: <PICT:0718852/IV (a)/1> In a machine for the continuous spinning of textile fibres requiring wet-processing treatments, particularly viscose rayon, and comprising two rollers 10, 11 arranged with their axes slightly skew and tilted with respect to the horizontal, so that thread led on to the rollers at their lower end progresses upon rotation of at least one of the rollers in a helical path around the rollers to their upper end, one of the rollers 10 is divided along its length into a number of treatment zones separated by flanges 12 so that processing liquids fed to each zone and collected in respective troughs arranged beneath each zone are not contaminated by liquid fed to other zones.  The processing liquids are applied to the roller 10 through the pipes 16 which are so arranged with respect to the rollers that the left-hand surfaces of the flanges 12 are not wetted.  A further drying zone 27 is provided on the roller 10.  This is heated by liquid passing within the roller and is thermally insulated from the remainder of the roller by the zig-zag gap 18.  If desired, Fig. 7 (not shown), a further conditioning zone wherein the thread is moistened to a desired degree may be provided.  These two further zones may be partially enclosed.  In a modification, Fig. 5 (not shown), each flange 12 is replaced by a double flange which projects to extend both sides of the corresponding upstanding wall of the trough 14; thus in this arrangement both surfaces of the flange may be wetted.  Flanges corresponding to the flanges 12 may be arranged around the roller 11.  Means, Fig. 6 (not shown), may be employed for wiping liquid from the surface of the roller 11 and restoring it by means of a duct to its appropriate zone of the roller 10. The roller 10 may have a conical shape or be stepped so as to effect a desired degree of stretch or contraction of the thread as it progresses along the roller.

Abstract: 726,639. Vacuum chambers. GENERAL ELECTRIC CO. Sept. 25, 1953 [Sept. 27, 1952], No. 26492/53. Class 8 (2). [Also in Groups XIII and XXII] A sealed panel of the vacuum type for refrigerators consists of a pan-shaped wall 3 and a flat wall 2 the edges 5 of which overlap the edges 6 of the wall 3 to hold the walls together. The panel is filled with glass fibre insulation 4. Prior to assembly the exterior walls of the panel are coated with porcelain frit, the enamel is wiped from the edges of the panels and the panels are fired in an oven. After firing the seamed joint is joined and the edges thereof spot welded and coated with porcelain enamel frit 8. The panel is heated to below the firing temperature of the frit in an autoclave 9 from which the air is evacuated which also draws the air from the interior of the panel through the gaps in the partially seamed joint. A high frequency induction heater 13 then fires the frit 8 and upon cooling the joint is sealed. In a modification the enamel frit may be applied to the entire panel after the panel has been formed. In a further modification the enamel frit is not wiped from the edges 5 and 6 prior to firing of the panels and after seaming and spot welding the edges are coated with enamel frit as at 16 Fig. 3. In a still further modification the walls 1 and 2 are coated before assembly with porcelain enamel frit not only on the exterior surfaces but also on the interior surfaces in the region of the edges 5 and 6 as at 17 Fig. 4. Specification 715,174, [Group XIII], is referred to.

Title: Improvements in or relating to load carrying tipping vehicles
IPC: B62D25/18
Filed: 1953-10-01
Abstract: 737,357. Tipping vehicles. LIVERPOOL, LORD MAYOR, ALDERMEN & CITIZENS OF THE CITY OF, and HAUGHTON, E. Sept. 22, 1954 [Oct. 1, 1953], No. 26904/53. Class 108 (1). A tipping vehicle has a wheel arch 14 provided with an upper panel 3 and a valance 5, which arch is upwardly and downwardly displaceable in and relatively to an opening 11 in the floor 10 of the body. The arch is pivoted at 9 to the floor, and in the normal horizontal position of the floor is supported by a chassis outrigger 20. When the body is tipped about an axis 16 the arch moves rearwardly relatively to the body and disengages itself from a latch on the outrigger 20, but does not pivot until the floor surface tips to the plane of the panel 3. Further movement of the floor then lifts the arch by means of a connecting chain 18 and carries it upwardly so that the floor 10 and the panel 3 remain coplanar. The valance 5 moves within the hollow side wall of the vehicle and covers the wheel opening therein. The opening 11 is provided with sealing strips, and a scraper strip is provided on the inner panel 13 to remove material adhering to the valance 5. In a modification the arch is pivoted to the chassis. The movement of the arch may be limited by a cylinder and dash pot mechanism 19. Steps 24, 25 may be folded upwardly into the vehicle so that the underside of the step 25 serves to extend the platform 10. To reduoe the effort required to raise the step 25 and to provide a retaining force, a torque is applied by a spring 48 connected to a crank arm rotatable with a gear ' 47 meshing with a gear 46 on the step 25.

Abstract: 362,522. Apparatus for low temperature carbonization. PUENING, F., O'Hara Township, Pennsylvania, U.S.A. Sept. 10, 1930, No. 27026. Convention date, Oct. 1, 1929. [Classes 51 (i), 51 (ii), and 55 (i).] In carbonizing apparatus of this type in which the coke chambers may be enlarged through movement of their walls for discharging the coke, the chamber walls are hollow and internally heated, and a housing encloses the chambers and walls and serves to collect the distillates and: pass them to an outlet pipe. A housing 1 contains a number of hollow walls 2 supported on beams 3 each pivotally connected by a pin 4 to a beam 5, and resting by wheels 6 on a rail 7, the lower end of each wall being anchored by a bracket 9 to the housing 1. Thus, each wall swings about a vertical axis, and extensions 12 are provided which are joined to flexible metal sheets 13 forming sides of chambers 14, 15 which communicate with a source of heating gases. The walls are moved by arms 16 operating vertical shafts 17 which by linkwork and levers actuate rods 20, 23 attached to the walls and having different lengths of travel. The bottom of the coking chambers formed between the hollow walls are closed by doors 25, operated by a windlass 29. A movable platform 31 carries coal hoppers 37 each closed by a gate 38 controlled by a lever 39, auxiliary hoppers 40 being provided to supply coke breeze to the edges of the heating walls for sealing purposes. Coke pushers 42 serve to remove the coke from between the walls when these are separated. The side-plates of the heating walls are spaced by baffles 53, 54, which distribute the heating gases supplied by a fan 60 from a combustion chamber, and circulated through the heating walls 2, and back to the fan. The heat losses are made up by hot gases from the combustion chamber, surplus heating gases escaping through an outler 65, and reversing valves 75, 76 being provided. Dampers 83, 84, Fig. 3, are normally closed, but are opened to allow hot gases to circulate outside the hollow walls 2 until distillation starts. In operation, after the spaces 58 are filled, the main coking spaces between the heating walls 2, which spaces are about three inches thick, are charged with fuel which is heated to about 1200‹ F., the path of the heating gases being periodically reversed. The distillates escape through an outlet 86. The coke is discharged by separating the heating walls and dropping the doors 25, the pushers 42 being operated to remove adhering coke. On opening a door 90 provided with a liquid seal 91 the coke falls into a trolley 89. In a modification, Fig. 5, the coal between hollow movable heating walls 96 is heated by a heating fluid such as molten metal, or a fused salt, which is heated in a coil 103 and circulated by a propeller 108 through metal tubes 98, 99, and return conduit 102. The combustion gases from a burner 106 may be passed through dampers 114, 115 to .liquefy the heat-conducting material before distillation takes place.
