Abstract: 810,924. Extrusion dies. MILLER, R. W., MILLER, B. A., and HARKENRIDER, R. J. April 9, 1956, No. 10750/56. Class 87(2). Multiple tube structures with walls of generally polygonal arrangement integrally formed at corners of common walls are extruded from rubber-like, bituminous or other fluent material, according to their purpose, through a die assembly comprising a screen plate 11 having passages 24 for material to be extruded, marginal pieces 18, 19 and a group of cores 14 secured to the screen plate, each core having head and base portions 21, 20, Fig. 12, adjacent head portions of the cores being spaced narrowly to form extrusion die passages 33, Fig. 10, and each core and marginal piece having grooves 22, 28 respectively which mate with corresponding grooves in adjacent cores or marginal pieces to form continuous passages for supplying the extrusion die passages with fluent material from the screen plate passages. The corresponding head and base portions in the marginal pieces are 27, 26 and the material passes from the passages 24 to the grooves 22, 28. through feed grooves 23. In the above embodiment there are thirteen cores of hexagonal form, a multiple hexagonal tube structure so produced having good pressure resistance and recovery properties. The cores may be of other form, e.g. square, 35, Fig. 13, with marginal pieces 36, 37, or modified diamond shaped, 38, Fig. 14, with marginal pieces 39, 40. Proportions are given of a synthetic rubber composition for a hexagonal tube structure to serve as a spring element in journal box lubrications.

Patent GB-1506282-A (GB)
Title: Insulating window panes
IPC: C03C27/12
Filed: 1975-03-14
Abstract: The heat-insulating window pane has at least two glass panes. These are spaced apart from one another by means of metallic spacer rails in each case. In order to produce the heat-insulating window pane, first of all those surface sections of the glass panes (2,6) coming to bear on the spacer rails are metal-coated (region 10). The spacer rails (8) are then inserted and heated, with the result that a metal bond occurs. In this process, the spacer rails are heated by means of current eddy, high frequency and/or ohmic heat, essentially no temperature gradient occurring with respect to the cross-sectional surface and longitudinal direction of the spacer rail.

Title: Improvements in or relating to the manufacture of polymeric substances
IPC: C08F10/00
Filed: 1944-06-06
Abstract: A polymer produced by polymerization in solution in the presence of a Friedel-Crafts catalyst is treated, at a temperature sufficient to split off the halogen as hydrogen halide and under pressure, with a solution or suspension in a liquid vehicle of a neutralizing agent. Specified Friedel-Crafts catalysts are aluminium chloride or bromide, ferric chloride, boron trifluoride and anhydrous hydrofluoric acid. Specified polymers are those of indene, coumarone, styrene, styrene-coumarone and propylene, while the neutralizing agent may be alkali metal or alkaline earth metal hydroxide, carbonate or bicarbonate.  The liquid vehicle may be water and/or an organic liquid or mixture of organic liquids. Intimate contact between the polymer solution and the neutralizing agent is obtained by passing the two together through a long narrow-bore tube, preferably in the form of a coil. The temperature is maintained between 180 DEG  and 220 DEG  C. when coumarone and/or indene resins are so treated. After treatment, the polymer solution may be washed with water to remove any neutralizing agent and halide salts therefrom.

Filed: 1917-07-30
Abstract: 117,511. Mackie & Sons, J., and Sinton, V. W. July 30, 1917. Spindle apparatus.-The bob bins in a flaxspinning frame are dragged by brake blocks 11 disposed on opposite sides of the bobbin, and pivoted on arms 12 drawn together by a spring 13 and arranged as to allow free lateral movement. The initial drag is adjusted by the screws 14 or by an adjustable graduated finger 28 on the end of one of the arms 12. The drag is adjusted as the bobbin is filled by a cam 18 operating between the ends of the arms 12. The cam 18 is mounted on a shaft 19 rotated either continuously or intermittingly through a ratchet-driven shaft 23 operated by the rise and fall of the builder rail. A ratchet coupling may be introduced between the shaft 19 and the worm wheel 21 to allow further facilities for adjusting the initial drag. The bobbins, Fig. 3, are coupled) by pins 7 to drag-disks 5 of hard wood or lignum vitµ resting on bosses 4 on the rail 1. The disks 5 are screwed to sockets or tubes 6 rotating freely on the spindles 3. The spindles work through cups 8 containing lubricating pads 9. The brake blocks may be applied directly to the bobbins. Self-alining spindles may be employed. Specifications 117,510 and 117,689 are referred to.

Abstract: 102,133. Beresford, R., and Daly, C. F. Aug. 4, 1916. Addition to 20346/14. Closets, urinals, &c., disinfecting.-The disinfecting-appliance described in the parent Specification is modified by hinging the disinfectant reservoir 1 to a casing 3 on which a small receiving- tank 6, connected by an upper pipe 16 to the down-pipe of the flushing system, and by a pipe 11 to the suction device 10, 12, 13, is adjustably mounted. Two pipes extend from the reservoir into the tank 6, one 4 being an air-pipe extending to the top of the reservoir and provided with a cut-away end to prevent air locks, and the other pipe being situated at the side of the pipe 4 and extending just through the base of the reservoir. The reservoir is filled through either of the pipes after it has been turned on its hinges into an inverted position. In operation, the suction in the pipe 14, which is connected to the down-pipe, causes the disinfectant in the tank 6 to rise in the pipe 11 and partly to fill the tube 10. When the flush ceases, the disinfectant falls back into the tank 6 and overflows down the pipe 16. The reservoir 1 may be removably mounted on the casing 3.

Both side chambers may be sealed off to determined whether drying has been completed, which is the case when a pressure sensor indicates no rise in the vapour pressure of the centre chamber. When the drying has been completed the centre chamber is filled with nitrogen to break the vacuum and to saturate the freeze dried material which is subsequently conveyed to room 16. The packaged freeze dried material is conveyed from room 16 to room 11 via air lock 20.
