Abstract: 574,004. Grabs. PRIESTMAN BROS., Ltd., and PRIESTMAN, S. H. April 1, 1944, No. 6098. [Class 78 (iv)] The jaws of a grab which are spread widely apart by a lazy-tongs linkage, are supported on brackets which are pivotedly connected to the extended ends 'of the outer members of the linkage and have a sliding link connection with the linkage, the sliding links being normally drawn up by the closing rope to close the jaws but may be released to allow the jaws to open for discharge when the rope is slackened somewhat without permitting the lazy-tongs linkage to expand. As shown in Fig. 1, the jaws comprising tines d<1> spaced along crossbars c are supported in brackets c which are pivoted at b to the members a of the linkage, and at g to links f provided with slots h engaging pins i on the linkage. The closing rope m is anchored to the linkage at n and passes round sheaves k on the links f to a sheave o and thence back to the crane over the sheaves k to a sheave q carried by a bracket r on the linkage. The opening rope s is attached at u to the linkage and passes round a sheave t on the linkage and then round a sheave on the bracket r parallel with and adjacent the sheave q to the crane. To discharge spoil from the grab without opening the lazytongs linkage, the closing rope m is paid out slightly to allow the links f to slide over the pins i and the brackets c to fall to a position c<1>. On paying out the rope m still further, the weight is taken more and more by the rope s and this causes the linkage to expand. Instead of slotted links f, bars may be used sliding through guides on the linkage. Specification 429,047 is referred to.

Filed: 1943-04-19
Abstract: 575,411. Light sensitive cells. STANDARD 'TELEPHONES & CABLES, Ltd. April 19, 1943, No. 6278. Convention date, April 24, 1942: [Class 40 (iii)] [Also in Groups II, III and XXXVI] In making a selenium element, such as is employed for electric rectifiers and light-sensitive cells, consisting of a coating of selenium on a base-plate, a single selenium wafer having appropriate thickness and area to produce the desired coating is first formed in a separate operation and the wafer is then placed upon the base-plate and fused thereto by heating the plate. The wafer may be formed by compressing powdered vitreous amorphous selenium between surfaces of a material not injurious to selenium, e.g. mica or aluminium, using a pressure of several thousand pounds per square inch at a temperature of about 120 C. It is preferable to make the wafer slightly oversize with respect to the base-plate if a complete covering of the plate is desired. The wafer of vitreous amorphous selenium may be converted into, the grey metallic state by heating it at a temperature of 170-217 C., say 200 C., before applying it to the plate. It is also possible to use wafers of red amorphous selenium. Fig. 5 shows the application of a preformed selenium wafer 8 to a base-plate 9 provided with a central hole 10 to form a selenium element.

Abstract: 371,106. Loom measuring stop-motions. ROBINSON, J. and ROBINSON, T. L., Ingham Street Ironworks, Blackburn. March 4, 1931, No. 6649. [Class 142 (i).] To effect stoppage of a loom at predetermined intervals,'for the insertion of headings and the like, a pivotally mounted finger a, Figs. 1 and 2, is caused to travel along one or more continuous tracks formed by a series of flanged discs h mounted on a spindle e which is rotated by chain and sprocket gearing g<1>, g from the take-up roller or other moving part of the loom, the action of the finger in its final position serving to actuate the usual weft fork mechanism. The discs h constituting the rotary member may be cut away at h<3> to allow the finger a to pass, under the influence of a spring a<1>, from one disc to the other or each disc may have part of the flange pushed over to meet the succeeding flange so as to form the equivalent of a spiral groove. The disc at the entrance end of the track is keyed to the supporting spindle and the remaining discs are secured thereto by pin and hole connections, each of the inside discs having a hole h<2>, Fig. 6, on each side of its connecting pin h<1> so that the gap h<3> in any one disc may lie to right or left of that of the preceding disc according to whether the stop motion is on a right or left hand loom. The finger a is set with one end on a ledge c<2> of the supporting bracket c where it bears against the first disc until an opening is presented to it and the other end is arranged against the curved face of a gravity actuated bolt d. As the discs rotate, the finger is moved in a horizontal plane until its forward end passes through a gap in the end disc, whereupon it assumes the dotted line position shown in Fig. 1 and allows the bolt d to fall forward and downward. When the bolt falls the weft fork is engaged by an extension d<3> or, in the event of the apparatus being accommodated below the loom, by a connecting rod j. A plurality of tracks, of the same or different lengths, may be formed by interposing one or more cam discs k which bring about stoppage of the loom and automatically reset the finger a, the bolt in each case being reset by hand. The disc at the exit end of the track may be provided with holes around its whole circumference so that the effective length of the track may be varied. A. free wheel sprocket is provided on the take up roller or other driving member to permit adjustment of the cloth tension and independent forward movement of the rotary member to set the feeler at the beginning of the track.
