Title: Implement for binding skeins of yarn and the like
IPC: B65H54/62
Filed: 1929-10-08
Abstract: 330,201. Vedovelli, M. Oct. 11, 1928, [Convention date]. Reeling-machines; tying in reeling.-A hand manipulated skein-binding implement comprises a row of rotatable slotted pins 3 and a needle 12, operated in the required succession by a thumb control 40. The latter moves a rack 39 which is in engagement with a pinion 38 fixed to a shaft 23. Attached to this shaft are two cams 24 and 25. The contour of the cams is such that during the first half revolution of the shaft 23 the rack 7 is moved and rotates the pius 3 through 90‹, whilst during the second half revolution the bar 28 is displaced and causes the lazy-tongs 34 to project the needle 12 through the slots 4 in the pins. The binding cord is held in the hook 13, passed round the lever 22, and threaded through the slots 5 which are initially coaxial. The pins are then inserted through the skein, and the control 40 moved in the direction of the arrow. The pins rotate through 90‹ and form loops, after which the needle carries the end of the cord through the deep slots 4 and consequently through the loops; on reaching the end of its travel, the needle passes between the springs 47, which retain the cord, whilst allowing the needle to return to its original position. When the needle is projected, a shoulder 21 thereon engages the tensioning lever 22, which is moved forward and so allows the necessary amount of cord to follow the needle. The binding obtained is shown in Fig. 6, the ends t, t<1> being subsequently tied together.

Title: Production of wax
IPC: C13B10/02
Filed: 1965-07-19
Abstract: Wax is extracted from sugar cane stalks, preferably before the latter are treated to remove juice, by brushing the exterior of the stalks, collecting the removed wax-containing materials and treating the collected material to purify the wax.  The purification may be effected by contacting the wax-containing material with an organic liquid solvent for the wax such as a paraffinic or aromatic hydrocarbon, particularly heptane or benzene, and with a bleaching agent, separating undissolved solids, and recovering the purified was (of M.Pt. aboe 75 DEG  C.) from the solution.  An initial purification of the wax-containing material from heavier solids may be effected by sedimentation in boiling water before the solvent purification.

Title: Improvements in and relating to electric multi-conductor cables
IPC: H01B9/00
Filed: 1926-12-03
Abstract: 273,167. Sonnenfeld, H. June 25, 1926, [Convention date]. Cables of special cross - section. - The outer covering and lead sheathing of a cable having a number of conductors is not made circular in crosssection, as usual, but is made to conform closely to the outer surface of the conductors in order to reduce the quantity of lead and insulating material required. Fig. 2 shows a three-core cable in which the conductors M are covered with the usual insulation J and are assembled with a padding C4 of insulating material between them. The belt insulation P, the lead sheath 0, and the armouring P2 are shaped as shown, thus requiring less material than would be necessary if the casing were cylindrical. The padding C, which fils the spaces between the conductors and the casing, also requires less material. The use of less material enables the heat generated by the cable to be dissipated more easily. Armouring.-In sheathing the cable, the lead press is provided with suitably shaped dies and counter dies, and the cable drums can be rotated if the conductors are to be twisted. Alternatively, the dies and counter dies can be rotated in the press. In another method, the dies are of circular cross-section and produce a sheath which has a circumference equal in length to that of the required sheath. The lead cylinder, as it forms, shapes itself to the outline of the cable.
