Filed: 1955-04-21
Abstract: 806,694. Splitting-machines. SCHULPEN, K. H. N. April 21, 1955 [Jan. 31, 1955], No. 14733/58. Divided out of 806,693. Class 31 (1). In a method of manufacturing a slab of material consisting of a multi-cellular thermoplastic synthetic substance, e.g. a polyester of polyurethane and a di-isocyanate, a slab of said substance having a closed surface layer is placed, if necessary in stretched condition, with the closed surface layer on a perforated grate or the like, whereupon the closed surface layer is subjected to such vacuum that it is sucked against the grate and finally the parts of the slab projecting over a certain height beyond the closed surface layer are cut off in such a way as to obtain a slab of substantially uniform thickness. As shown, a slab 5 is placed with its closed surface layer on a perforated plate 3 to which suction is applied and cuts are made parallel to the plate by means of a knife located at various positions 7 to 10. Additional cuts may be made in the slab perpendicular to the plate.

Abstract: 993,058. Ring-spinning apparatus. JAMES MACKIE & SONS Ltd. April 10, 1962 [April 25, 1961], No. 14943/61. Heading D1D. In a ring-spinning frame where the spindles are formed or fitted with balloon-restricting heads 19, mechanism is provided to adjust the vertical position of the lappets 24 so that they are closer to their respective heads at the end than at the start of a set. Each lappet is hinged at 31 to a bracket secured to a common spindle 30 which can be moved up and down by an arm 35 depending from a second rockable spindle 36 which has a depending arm 37 fitted with a cam-follower 38. This rides on an inclined surface of a lateral extension of a bar 11 which is connected to the ring-rail 4 by chains 12 passing over pulleys 13. The bar is reciprocated to provide the traverse and steadily moved longitudinally to provide the gain; as it reciprocates, the follower 38 rises and falls with the inclined surface, and as the bar moves longitudinally, the follower changes position to rock the spindle 36 and lower the mean position of the lappets. The inclined surface may be such as to lower the lappets steadily or intermittently without reciprocation or to affect the position of the lappets only in the final stages of the wind. The head 19 may have four radial wings 20 and be mounted on a short extension 18 of the spindle.

Title: Process for the production of high molecular weight polymers of ethylene
IPC: C08F2/00
Filed: 1955-05-25
Abstract: Ethylene polymers of molecular weight greater than 100,000 are prepared by polymerizing ethylene in a substantially dry phase in the presence of granular or pulverulent mixtures comprising polyethylene and solid or liquid catalysts, effective for the polymerization of ethylene at pressures below 200 atmospheres gauge, at temperatures below the caking or sintering temperature of the mixtures, while continuously mechanically dividing and/or agitating the mixtures whereby the ethylene is intimately contacted therewith.  The catalyst may be diethyl aluminium monochloride, preferably mixed with titanium tetrachloride and a C9-C11 aliphatic hydrocarbon fraction, and may be sprayed into the reactor as the polymerization proceeds.  The reactors may be provided with stirring, kneading or grinding devices, and the mixture supported on cooled surfaces, or the polymerization may be effected in fluidized bed or suspensoid processes.  The reaction may be effected continuously in one or more stages, the gases moving concurrently with or countercurrently to the mixture which may be comminuted between stages.  The reaction may be started with gases poor in ethylene, e.g. tail gases, or in a liquid phase, a dry powder for use in the invention being obtained by filtering or centrifuging.

A device for measuring the displacement of a body from a datum position comprises two permanent magnets 3, 4, Fig. 1, held inside an iron ring 2 by a non-magnetic spacer 7 and polepieces 5, 6 and associated with a first armature 11 pivoted at 10 to swing between contact stops 12, 13 and a second armature 8 slidable between the polepieces 5, 6. In operation, with armature 8 initially central, armature 11 is made to swing by energizing a stationary coil 14 from an A.C. source 32, Fig. 3, the time of dwell on each contact 12, 13 being made equal by a D.C. biasing current from a battery 31, and indicated by zero resultant current in a meter 40 connected to the armature 11. If armature 8 is now displaced relative to the polepieces 5, 6 the flux distribution is changed so that the times of dwell of armature 11 at contacts 12, 13 become different, and meter 40 will give a reading indicative of the extent and direction of the movement of armature 8. Contacts 12, 13 may be associated with additional relays and signalling circuits.

Abstract: 552,362. Vehicle wheels. JACKSON, L. MELLERSH-(Kelsey-Hayes Wheel Co.) Oct. 11, 1940, No. 15177. [Class 144 (ii)] Relates to rims of the kind having an endless rim-base 1 with an integral flange 4, and a detachable endless side flange or ring 2, which is sprung into position on the rim. The base 1 has a gutter 3 the outer wall 5 of which is formed with two notches 15, 17, which may both be through-notches or, as shown, the notch 17 may be a triangular throughnotch and the notch 15 a pocket formed in the wall 5. The ring 2 has a single rectangular notch 16 (shown in chain lines in Fig. 4) slightly longer than the part 6 of the wall 5 upstanding between the notches 15, 17. Adjacent the notch 17 the wall 5 is chamfered at 18. To assemble the rim, the notch 16 of the ring is interlocked at a slight angle, as shown in chain lines in Fig. 4, with the wall-part 6 of the rim-base, so that peripheral relative movement is prevented, and then, working in the direction of the arrow x, the ring is gradually eased over the wall 5 and seated upon the annular faces 9, 12<SP>1</SP> of the wall. Slight relative peripheral motion is then effected so as to mask the through-notches and prevent entry of water or dirt in to the gutter 3.
