Abstract: 283,096. Broadbent, W. Nov. 12, 1927. Crushers with vibrating jaws.-In a granulator, stone-breaker, or ore crusher, &c. of the kind in which the material is crushed between a fixed member and a movable member pivoted at the bottom, the movable member is shaped and mounted to rock on an adjustable shaft or pivot so as to be balanced when in mid position, the operative closing force being applied near the top in a direct thrust through the medium of togglelevers the adjacent ends of which are mounted in a vertically-reciprocating member on the driving-shaft, and the closing action of the toggle-levers being exerted against the pull of a resilient timber member at the back of the machine, the pull being applied above the togglelevers so that the movable member is pulled backwards when the toggle pressure is released. As shown, Figs. 1 and 2, the middle or eccentric part 9 of the driving-shalt 6 rotates within a circular opening in a rocking member 10 which receives on opposite sides of it the inner ends of toggle-arms 11, one of which at its outer end engages a fixed thrust-block 12 while the other engages the back of the moving jaw 13. The jaw 13 is pivoted at its bottom end low down on the machine on a rock-shaft 14 which is adjustable to move the jaw 13 to and from the fixed jaw 15. A rod 16, pivoted near the top on the back of the jaw 13, is pivotally connected at its outer end to the top end of a stout ash plank 18 pivoted at 19 low down on the back of the machine. The member 18 bears against a thrust block 20 on the back of the machine. Screwed rods 24 with nuts 25 are provided for adjusting the slidable bearings 23 of the shaft 14. Shims 26 are fixed behind the bearings after adjustment to take the crushing strain off the rods 24. The face of the fixed jaw 15 is set back slightly at the top and bottom, and both jaws are provided with detachable working-faces.

Apparatus for detecting the pour-point of a liquid 2 comprises a mercury thermometer 8 bent at right angles and mounting at one end a disc 10, the thermometer being freely suspended in the liquid 2 from a strip 5 e. g. of berylliumcopper alloy, and counter-balanced by a weight 11. A vane 6 is attached to the strip 5 and extends between a photo-cell detector 12 positioned adjacent an electromagnet 13. In use, a cooling unit 3 is set in operation, and a current passed through the electromagnet 13 at five minute intervals, moving the vane 6 in the path of photo-cell detector 12. When the liquid reaches its pourpoint temperature, movement of vane 6 is halted, as the disc 10 is no longer freely movable in the setting liquid. In a modification, see Figs. 2-4 (not shown) a movable vane is attached by brackets to a copper-beryllium suspension tape which is attached by further brackets to the instrument support. In this case, a platinum resistance thermometer is used.

Abstract: 627,058. Yarns. BRITISH CELANESE, Ltd. Oct. 17, 1946, No. 30940. Convention date, Oct. 17, 1945. [Class 120 (iii)] A doubled yarn is formed by winding two component yarns only, made of freshlyspun continuous artificial filaments, on one package so that different yarns are exposed at the two shoulders of the package, followed by removing the yarns simultaneously to form the doubled yarn, in order that the portions of the component yams exposed at the shoulders are staggered in the doubled yarn to render its dyeing properties more uniform. Yarns A, B are laid on a bobbin 1 in spaced side-by-side relation by a traverse guide 3. The yarn A forms the shoulder 8 on one side of the bobbin and the yarn B the shoulder 9 on the other side. When the yarns A, B are unwound and twisted, those portions which have had their dyeing properties modified by exposure at the shoulders 8, 9 will be staggered. Specification 623,753 is referred to.

Title: Improved driving mechanism for circular looms
IPC: D03D37/00
Filed: 1935-11-09
Abstract: 465,610. Circular looms. BRITISH CELANESE, Ltd., and JABOULEY, J. Nov. 9, 1935, No. 31045. [Classes 142 (i) and 142 (ii)] The ring 13 carrying the vane wheel support- - ing brackets 12 is normally driven by a gear 20 which is carried bv a lever 27 and is driven by a pinion 19 on a shaft 18 journalled in a fixed ring 25 and driven from a motor 15. The lever 27 is freely pivoted on the shaft 18 and has a stud 28 extending through a curved slot 29. The torque applied by the rotating pinion 19 tends to swing the lever and gear20awayfrom the ring 13, but normally the lever is held in the position shown by a spring-controlled latch 30 controlled by a spring-controlled latch 36 having an armature 38 attracted by an electromagnet 39. Upon thread failure, the electric circuit is broken, for example, as described in Specification 424,789, the catch 36 then releases the latch 30, which frees the lever 27 and thus swings outwards so that the gear 20 thereon no longer meshes with the teeth 21 on the ring 13, the rotation of which is stopped by a surrounding brake band 33 connected to the latch 30. The lever 27 may operate the spring-urged striker 45 of a trip switch included in the motor circuit, and its movement be limited by a buffer 43, which itself may be formed as a short circuiting switch. The buffer and striker may be rubber faced. The armature may be faced with a layer of a non-magnetic substance such as rubber or paper. The electromagnet may normally be energized. Pinions 23 supported on the ring 13 engage a fixed gear ring 24 whereby the vane wheel shafts are driven as the ring 13 rotates around the loom. In the arrangement described, the shuttles move around a stationary warp. The invention may be used, however, in looms with rotating warp threads and stationary shuttles, or with both the warp threads and shuttles rotating. Specifications 396,757 and 402,822 also are referred to and the Provisional Specification refers to Specification 463,484.
