Title: Improvements in apparatus for the manufacture of microporous plastic webs
IPC: B29C67/20
Filed: 1959-05-27
Abstract: <PICT:0872796/IV (a)/1> An apparatus for the continuous manufacture of a microporous plastic web by sintering a plastic powder layer comprises a heated drum rotatable about a horizontal axis, the plastic powder being applied adjacent to the apex of the drum which consists of a spokeless cylindrical shell ring guided by carrying or guide rollers, the shell ring being suspended from at least one carrying roller which engages the inside of the ring adjacent to its apex and the lower portion of the ring being free to expand downwardly when heated.  As shown, the carrying roller 3 is driven by belt 5 and in turn drives the shell ring 1 by means of the gears 4 and 2 in the sense of the arrow.  The feed hopper 6 for plastic powder is provided with a cooling jacket 7, and the powder applied to the ring may be smoothed by a roll 8, which is preferably water-cooled, and revolves at a lower peripheral velocity than the ring.  The powder may be applied directly to the drum after the latter has been treated with a parting agent, e.g. talc, or the drum may be covered first with a base layer 9 (e.g. paper or open-mesh glass wool fabric) fed from supply spool 10 via deflecting roller 11. Cover layer 12, which may be the same material as 9, is fed from supply spool 13 via deflecting roller 14, which also prevents a swinging movement of the shell ring 1. The product comprising the sintered layer 15 plus layers 9 and 12 is withdrawn by the rolls 16, 17 which may be used, if desired, for profiling the product.  The ring is surrounded by an insulated housing 18 containing heating devices, e.g. a radiant heater 19 in the first part of the sintering zone and resistors 20 for general heating.  In modifications, layers 9 and/or 12 may be omitted, or 12 may be replaced by an endless belt which is detached from the layer 15 behind the roller 17 and fed back to roller 14. Sinterable plastic powders specified are polyvinyl acetate, polyvinyl carbazole, polyvinyl chloride, polystyrene, poly-compounds of acrylic acid and methacrylic acid and esters; polymer mixtures and copolymers.

Title: Improvements in double butt hinges
IPC: E05D3/00
Filed: 1937-06-30
Abstract: 493,335. Hinges. PRATT, A. W., and ADAMS (VICTOR), Ltd., R. June 30, 1937, No. 18174. [Class 65 (ii)] A double-butt hinge, consisting of two integral vertical barrels 1, 2 accommodating check devices, has means constraining the door to swing only about the axis of the barrel appropriate to its direction of movement. When the door 4 swings in the direction X, Fig. 2, the upper door hinge plate 5 rotates with respect to the barrel 1 and operates the check device therein but when it swings in the direction Y the barrel 1 rotates about the axis of the barrel 2 to which it is rigidly attached and causes the barrel 2 to rotate with respect to the collar 2a of the door post bracket 2c and operate its check device. Thus, as the door swings from one side of the doorway to the other, the axis of rotation is transferred from one barrel to the other so that the lower hinge plate 7 must be adapted to change its axis of rotation and also must be securely attached to the cylinder about which it is rotating. The hinge plate 7 and the door-post hinge bracket 7a, Figs. 5 and 6, are each provided with a pair of lug-like parts 8 and 10, 12 and 13, one of each pair being a shallow hollow cylinder 10, 13 and the others 8, 10 having an arcuate rib 9, 15. The upstanding parts 10a, 13a of the cylinders 10, 13 are, when the hinge is assembled, rotatable in the lower ends of the barrels 1, 2, and when the door is in the closed position the cylinders 13, 10 accommodate the ribs 9, 15. If the door is swung in the direction X, the arcuate rib 15 will rotate about the axis of the barrel 1 and move through the opening 11 in the cylinder 10, whilst the cylinder 13 will also rotate about the axis of the barrel 1 and cause the opening 14 to move into a position out of register with the end of the rib 9 so that it is impossible to move this rib out of the cylinder 13. If the door is swung in the direction Y the rib 15 rotates in the cylinder 10 and opening 14 of the cylinder 13 passes freely over the rib 9. The rib 15 is retained in the cylinder 10 as its end moves out of register with the opening 11 during this movement.

Title: Improvements in or relating to chamber ovens
IPC: C10B37/06
Filed: 1935-06-25
Abstract: 447,815. Coke ovens. OTTO & CO., GES., DR. C., 9, Christstrasse, Bochum, Germany. June 25, 1935, No. 18193. Convention date, Oct., 6, 1934. [Class 55 (i)] To accelerate the distillation of a coke oven charge, vertical holes are formed in the charge which have an oblong crosssection the greater dimension extending in the longitudinal direction of the oven chamber. The holes 37 are made by mandrels each of which has a hollow cylindrical body 44 to the end of which are hinged at 51 two U-shaped pieces 47, 48. To the lower outer ends of these are hinged at 52 two triangular pieces 49, 50 held at the apex by a hinge bolt 54 fixed to a rod 53 guided by a piston 55. When hanging freely, the pieces overlap so that the end is not of a larger cross-section than the main part 44. When contact is made with the charge 36, the end is expanded to assume the shape shown in Fig. 6b, and when the mandrel is withdrawn, the point collapses, so that it may pass through passages 42 in the cover. The expansion of the hinged halves may alternatively be effected by internal springs which are compressed when the mandrel passes through the oven covers.
