Abstract: 560,322. Tipplers and spreaders. STRACHAN & HENSHAW, Ltd., and GROSSMITH, G. W. Aug. 20, 1942, No. 11734. [Class 78 (iv)] Loose material is handled in bulk by a gantry structure 10 movable along a railway and fitted with two track ramps whereby wagons 37 can be run up on to rails on the gantry platform 12. A wagon tippler 31 may be located within the structure to discharge the contents at the side of the railway, the operation being by a winch 33 and cable 34. Top stops 35 connected to counterweights 36 take the weight of the inverted wagon. The top posts of the structure support a horizontal girder 11 along which can run a support 13 for a beam 14 counterweighted at 23 and upheld at its outer end by a trestle 24. The connections 11a and 24a of the beam 14 to the support 13 and trestle 24 respectively are of a universal type, that at 11a permitting swinging of the beam 14 in one direction into parallelism with the railway track, the top posts being staggered relatively to the girder 11 to allow of this. The trestle 24 may have ground-engaging feet 25 or may rest on wheels running on a single track. A telpher 20 riding on the beam 14 may have its grab 21 controlled from a cabin 22 located on the telpher or on the inner end 23 of the beam. The telpher may travel beyond the trestle 24, and, when the grab-operating cabin is on the beam end, may support an observation cabin. The telpher is brought to the end 23 when it is desired to raise the trestle 24 off the ground, either for re-alignment or for bringing the beam parallel to the railway for transport. A simpler construction is described in which the tippler is omitted. Specification 558,181 is referred to in the Provisional Specification.

Title: Improvements in or relating to knitted articles
Inventor: WOOLLEY GEORGE HENRY
IPC: A41B11/00
Filed: 1962-03-30
Abstract: 1,034,422. Fabrics. WHYTE & SMITH Ltd. April 1,1963 [March 30, 1962], No.12218/62. Heading D1K. A tubular knitted fabric for a knitted article such as the calf, instep and sole portions of a hose comprises inner and outer tubes of separate yarns which are united at spaced single or groups of wales W to form a cellular structure by intermeshing loops K, K1 (Fig. 4) of the two tubes. The inner tube is preferably of a soft yarn such as wool while the outer tube is of a hard wearing yarn such as nylon. The yarns may be of the same or different colours and in the latter case a striped effect can be obtained. If the loops K of the inner tube are taken into the outer tube as Fig. 4 a mock rib effect is obtained on the outside but if the loops of the outer are taken into the inner tube a true rib effect is obtained (Fig. 8, not shown). A hose in accordance with the invention can be knitted on a superimposed cylinder machine when often a 1 x 1 rib top is produced by feeding nylon stretch or bulk yarn to the two sets of needles at front and back feeding stations, with the incorporation of an elastic yarn if desired, the top stitch bolt cam is withdrawn so that the top set of needles miss the nylon yarn but pick up a wool yarn which is introduced. A bottom stitch bolt cam is also withdrawn so that the bottom set of needles miss the wool yarn. Inner and outer tubes of wool and nylon are thereby knitted, the interconnections at the spaced wales being obtained by jacks of a patterning system acting on spaced needles of the bottom set to knit the wool yarn as well. High splicing at the heel may be carried out by the introduction of a splicing yarn with the wool yarn but the heel itself is produced in the usual reciprocatory manner. Reversion to circular knitting for the sole and instep is effected with an additional splicing yarn for the foot if desired. Finally for the toe the machine again reciprocates in the usual manner. The wool yarn may be replaced by ootton and the nylon by terylene (Registered Trade Mark).
