Title: Improvements in rotary hectographic copying machines
Inventor: BROWN ROLAND
IPC: B41L7/08
Filed: 1952-03-21
Abstract: 727,149. Duplicating machines. BLOCK & ANDERSON, Ltd. June 22, 1953 [March 21, 1952], No. 7376/52. Class 100 (2). A hectographic duplicating machine of the kind having a rotary drum is adapted for printing with a master sheet longer than the periphery of the drum by the provision, on the side frame of the machine, of a latch lever 12 movable from an idle position to a position (shown) in which it is adapted to co-operate with the control mechanism of the damping device to retain the latter in the operative position after it has assumed that position under the action of the usual control, by the initial rotation of the drum from rest position so that, at the end of each complete rotation the damping device is prevented from returning to its inoperative position. The damping device is mounted in a casing attached to a square shaft 7 rotation of which brings the damping pad into contact with the copy sheet. The shaft 7 carries a control arm 5 to which is adjustably connected a spring-loaded lever 2 having a cam follower roller 3 at its free end for engagement with cam 4 rotating with the drum. The latch lever 12 is pivoted at 12a and has a shoulder 15 formed on its lower end co-operating with a pin 16 on lever 2 and an upper pin 14 engaged by a setting lever 9 held in either of two positions by a pin 11 co-operating with a retaining spring 10. A trip lever 17 also pivoted at 12a is spring-urged to bear against a pin 18 on lever 12. In operation, with the setting lever 9 in the position shown to adapt the machine for the "ong" master sheets, initial rotation of the drum causes cam 4 to displace lever 2 and move the damping pad into contact with the copy sheet. Lever 12 swings into latching position (shown) under the action of spring 13 and retains the lever 2 in this position when, due to the fall part of cam 4, it would normally return to inoperative position. To unwind the master sheet, it is necessary to rotate the drum in the reverse direction and this effects release of the latch lever 12 by engagement between a pin 20 on the drum and lever 17, causing anticlockwise rotation of latch 12. Rotation in the other direction is allowed by the lever 17 yielding against its spring when engaged by pin 20. When the lever 9 is moved to the other,position, the latch lever is rotated out of engagement with pin 16 and the damping device therefore returns to inoperative position at the end of each revolution of the drum. Specification 543,540 is referred to.

Filed: 1957-03-07
Abstract: 881,865. Finishing yarns. ENGLISH ROSE Ltd. Feb. 19, 1958 [March 7, 1957], No. 7644/57. Class 120(3) Crimped stretch yarn is made by continuously feeding a thermoplastic, e.g. nylon or polyester, yarn into the entry end of an open-ended tunnel and continuously extracting it from the exit end thereof at a linear speed less than the input speed so that, in continuous flow, the yarn arranges itself in the tunnel in regular sinuous form without being compacted, and heat-setting the yarn in such form during its travel in the tunnel or subsequent thereto. The emerging yarn may be gripped between travelling surfaces, heated and cooled. The tunnel may have major and minor transverse dimensions such that the sinuosities are formed generally in the plane of larger dimension, e.g. the dimensions may determine the amplitude of the sinuosities and constrain the yarn in a single plane. If the tunnel is of circular cross-section, the sinuosities occur in different planes haphazardly or the yarn may form a helix, and the yarn may be set in such condition or it may be forced into one plane and set. In the operation of apparatus shown comprising a crimping and setting unit 17, yarns 10 drawn from packages 16 pass successively through eyelets 19 and 20, a converging grooved guide 28 tapered at 28b, the nip of feed rollers 11a, 11b, and a tunnel within a crimping tube 13 having chamfered ends to fit closely between opposed surfaces of feed and extraction members, Fig. 3 (not shown) and longitudinally divided into two separable parts. On emerging from tube 13, the yarn is trapped between, forwarded and heat-set by endless metal bands 14a, 14b provided with heaters, as at 30, 31, and coolers 32, 33, and travelling over rollers 15a, 15b, 15c, 15d and 27a, 27b, 27c, 27d. The crimped yarns leaving the bands pass through a diverging grooved guide 29 tapered at 29b, guides 21 and 22, to take-up spindles 18. A motor 24 operates all driven parts of the apparatus through chains and sprockets, belts and pulleys, and/or gears. The unit 17 is divided into two parts hinged at 50 to facilitate threading- up.- The tunnel may be vibrated laterally by electric, supersonic and/or hydraulic means, Figs. 13 and 14 (not shown).

Title: A continuous process for wasting arsenopyrites ores to obtain elemental sulphur and sulphur dioxide, practically free of arsenic
IPC: C22B1/02
Filed: 1954-03-17
Abstract: <PICT:0757547/III/1> A continuous process for roasting arsenopyrites ores comprises preheating the ore in a first de-arsenication stage by direct contact with a portion of the sulphur dioxide gases from the subsequent roasting stage, to a temperature, e.g. 500-550 DEG C., such that arsenic compounds are distilled off but labile sulphur is not, passing preheated ore to a second distillation stage, where it is directly contacted with the remainder of the sulphur dioxide gases from the roasting stage to distil off the labile sulphur, e.g. at above 700 DEG C., and feeding the residue from the distillation stage, together with any preheated ore which was not fed to the distillation stage, to the roasting stage.  In the apparatus shown the three stages are superposed fluidized beds in a single vessel 1. Ore from 5 is fed into preheating bed on grid 4, whence part passes through downcomer 9 to distillation bed on grid 6, and part passes direct to roasting bed on grid 8 through downcomer 11.  The ore from the distillation bed passes to the roasting bed through downcomer 10. Part of the sulphur dioxide gases from the roasting bed passes through funnel 14 into direct contact with the ore in the preheating bed and the As2S2 distilled off may be condensed in 18.  The rest of the sulphur dioxide passes through the distillation bed and through pipes 17 in indirect contact with the preheating bed and the sulphur distilled off is condensed in 21.  Air or oxygen-enriched air for roasting enters at 13, and ore may be fed direct from hopper 5 to the roasting bed through 7, or sulphur dioxide gases freed from sulphur and arsenic may be recycled to 13 to assist in temperature control. Specification 755,259 is referred to.
