Abstract: 192,354. Santal¾ y ArtÚs, M. E. Jan. 28, 1922, [Convention date]. Hank type.--In a hank dyeing, bleaching, finishing, &c. machine, the hanks 39 are suspended from rods 38 bridging a pair of endless chains 3, and by these they are carried through the liquid in a vat 2 and are during their passage caused to travel through a zigzag part around and between pairs of squeezing rollers 8, 9; the hanks are fed over the upper roller of each pair. through the nip of the rollers, and then underneath the lower roller. After passing from the bath, the hanks are carried through wringing rollers 14, 15 and thereafter the hanks pass through an extended path in the air and are re-treated in or are removed from the machine and the rods charged with a fresh set of hanks. The chains 3 are driven through sprockets 25 connected by spur and chain gearing 6, 17 with the main driving-shaft 16 which carries one of the wringing rollers: this shaft also drives through chain gearing 30, 31, 32, the shaft of one of the lower rollers 9, the other rollers being driven from this at the same speed by spur gearing with suitably interposed idlers. The gear ratios are arranged so that the peripheral speed of the rollers is slightly greater than the speed of the chains 3, by which means the hanks are drawn away from and are not creased by the supporting rods. To adjust the position of the upper rollers 8 screwed spindles acting in their bearings. pass through the columns 7 and' are actuated in unison fro'n a common shaft 13 provided with a hand wheel and connected by bevel gearing to the spir.dles; there is a separate adjustment for each upper roller. The chains 3 pass over guide wheels 40 by which they are stretched so as to enable the rods 38 to be removed and replaced; alternatively, the rods carrying the treated hanks may be removed at one point, and the rods charged with the untreated hanks, replaced at another point in the path of travel of the chains.

Title: Pattern recognition apparatus
IPC: G06V10/10
Filed: 1965-03-18
Abstract: A system for detecting the edge of a pattern of light comprises a two-dimensional array of exclusive OR elements, each element having a photoconductive layer with first and second regions and a load, e.g. an electroluminescent layer, and means for applying A.C. voltages half-cycle out of phase to the two photo-conductive regions, so that output from the load, or electroluminescent layer, develops only when one only of the two regions is illuminated. In embodiments, each element may have an input mask (Fig. 1), and the cancellation when both regions are illuminated may take place through the photoconductive layer (PC, Fig. 2) or, where this is not continuous, through an adjacent opaque conductive layer (OD, Fig. 3), optical feedback from the output electro-luminescent layer (EL, Fig. 1), being prevented by an opaque layer (OD, Fig. 1, 2, 3).  The opaque layer may be omitted, and optical feedback used to obtain a memory action.  An insensitive zone, where the edge to be detected falls on a wall of an element, may be avoided (Fig. 9), by using transparent, insulating, sloping walls (or, in a two-dimensional array, the device of Fig. 11).  Adjacent zones may be so arranged that edge extraction is obtained in any direction, i.e. thereis an exclusive OR in each of four directions around each electrode (TCl, Fig. 10).  Only one edge (light-dark or dark-light) may be detected by using a construction (Fig. 13) wherein input on one region activates the electroluminescent layer, but light on the other region shorts this layer.  The electrodes may be aluminium or indium, and the photoconductor cadmium sulphide or selenide.  An electrical output may be taken by detecting the voltages across the electroluminescent elements.

Abstract: 363,592. Bale-strapping machines. HOFFMANN, E., 30, Rheinaustrasse, Cologne, Germany. April 22, 1931, No. 11970. [Class 45.] In a bale-strapping machine wherein a lever 4 is swung from the position shown in Fig. 1 to that shown in Fig. 2 in order to lower a serrated wheel 2 into contact with the upper strap portion 6 and wherein the tensioning is effected by movement of a lever 3 operating a pawl 29 and ratchet 30 to rotate the serrated wheel, and the sealing effected by rotating a lever 11 which, through cams 10 coacting with rollers 18 on a knife block 8, lowers the knife block so that its cutting edges 17, Fig. 8, incise the sealing sleeve 7 and the portions of strap passing therethrough along their longitudinal edges, the initial movement of the lever 4 also releases the knife block, which has been held in an elevated position, permitting it to fall and engage the sleeve to guide it to a central position and hold it steady during the tensioning operation until the block is positively actuated by the lever 11 to incise the sleeve. The cam 10 on the lever 11 is provided with a pin 13 which when the lever is in the inoperative position shown in Fig. 1 engages beneath a hook 12 projecting from the knife block and so holds the knife block out of contact with the seal. The lever is also provided with a pin 14 which is engaged by a hook 15 positively operated by the lever 4. A spring- pressed plunger 16 engages the lever 11 when in its inoperative position so that when the lever 4 is moved counterclockwise to lower the serrated wheel and to release the pin 14 from the hook 15 the lever 11 is raised slightly to release the pin 13 from the hook 12 and to permit the knife block to fall and engage the sealing sleeve. The spare end of the strap is severed by a knife 19 which is provided with pins 21, Fig. 8, engaging an inclined slot 22 in the knife block. To vary the depth of the incision of the knife 19 the position of the knife may be adjusted by rotating a disc 23 which engages a recess 25 in the knife and travels along a screw-threaded stud 24. The disc can be locked in any adjusted position by a screw 26.
