Filed: 1930-08-25
Abstract: 350,818. Sheet-delivery apparatus. CAMCO (MACHINERY), Ltd., 63, Farring- don Street, London. Aug. 25, 1930, No. 25362. Convention date, Jan. 2. [Class 100 (i).] The delivery of sheets or signatures from a folding or other paper-handling machine to a horizontal slow-moving conveyer 16 is controlled, and the insertion of one folded sheet within another prevented, by a stop 39 engaged by the leading edge of a sheet A and adapted to be lifted by the succeeding sheet B deposited on the first sheet so as to allow the first sheet to pass, the lifting means being adjustable according to the thickness of the sheets or signatures. The stop 39 is integral with a U-shaped bracket 38 pivoted at 34, 35 to two parallel levers 30, 31 respectively, pivoted at 28, 29 to a block 26 adjustable by means of a set-screw 27 along a rod 24 arranged transversely of the conveyer 16. A rear extension 47 of the lever 31 has an internally-screwed block 50 pivoted thereto at 49 which carries a threaded rod 51 adjustable thereon by means of a lock-nut 61. A pin 52 through the end of the rod 51 limits the downward movement of the rod and therefore the upward movement of the stop 39 by contact with an angle strip 54 adjustably fixed to the block 26. A coiled spring 57 on the rod 51 bears at one end against the strip 54 and at the other end against a nut 59 threaded on the rod 51 and having a notched periphery engaged by a blade spring 60 looped around the rod 51 beneath the lock-nut 61. Fixed to the stop 39 is a curved plate 44 which can be adjusted as regards its distance from the belt 16 according to the thickness of the products being delivered by means of a bolt-and-slot connection 40, 46. In operation, the first-delivered sheet A is carried against the stop 39 and the succeeding sheet B is delivered on top of the sheet A and carried forward until it engages the plate 44 and thus lifts the stop 39 so as to allow the sheet A to continue its travel. The balancing action of the spring 57 on the levers 30, 31 is adjusted by means of the nut 59 according to the stiffness of the sheets. Specification 9566/14, [Class 100 (i), Feeding and delivering webs &c.], is referred to.

Abstract: 835,270. Knitting-machines; knitted fabrics. MACQUEEN, K. G. Aug. 19, 1957 [Aug. 20, 1956], No. 25433/56. Class 74 (2). [Also in Group XL (b)] A parallel or straight-bar knitting-machine has electrical means for widening or narrowing courses and performing other operations. Needle pattern control units 18 comprise photoelectric scanning devices 20 reading perforated tapes, and select one of three clutches 23 so that the needle either knits, tucks or is inactive. Each clutch consists of a disc 109 with a striker 107 (Fig. 10); the disc is made to rotate so that the striker moves the needle jack into the corresponding position by electromagnets 114 being actuated to bring disc 109 into contact with flange 113 on continuously rotating shaft 112. The cam carriage 4 is driven by a motor 6 controlled by a digital-analogue comparator 7 which compares a selected resistance picked by the instructions on a second tape, and read by a reader 9, with the resistance in a variable potentiometer 10 which is proportional to the distance of the cam carriage 4 from its end position, and determines the distance the carriage shall move so that when it stops the two resistances are equal. Electronic counting tubes may be used instead of the comparator. The second tape also gives instructions for units 12, 13, 14, 11 which select yarn, control stitch lengths, control cam carriage speed and perform various miscellaneous operations respectively. The yarn tension may be kept constant by a constant torque motor which feeds the yarn of the pirn. A number of slave knitting-machines can be connected to a master control unit by means of multi-wire cables and plug-in connections. The master control unit consists of an operation control reader, one or more needle pattern serial readers and a retransmission unit. Three-dimensional fashioning of garments is possible on the above machine, the desired shape being imparted by operating course-bycourse selected and variable numbers of needles.

Title: Improvements in or relating to the melting down of fats and other fusible materials
IPC: C10G73/40
Filed: 1953-11-18
Abstract: <PICT:0780799/III/1> <PICT:0780799/III/2> <PICT:0780799/III/3> Apparatus for rendering or melting oil- or fat-containing material, such as fish or fatty animal matter, and mineral wax-containing material such as bitumen, comprises a support for the material, a heating zone, mechanical means for causing the material to progress through the heating zone, for example a conveyer belt, and means for causing a gaseous heating medium to flow in a closed circuit and, while so flowing, to impinge on the fatty material from above or below, or both.  As shown, a burner 30 feeds hot gas to fan 11 which blows the gas to pressure chambers 13, 14, and thence through jets 26 on to the upper and lower sides of arcuate troughs 19 forming an endless conveyer belt 16 and containing the material to be rendered, the material being fed to the troughs by a hopper (not shown); the belt then passes continuously through the insulated outer casing 32 to the heating zone 15.  The used gas passes from zone 15 by means of duct 27 (partially cut away) back to fan 11 to be recycled or exhausted.  Instead of by burner 30, the gas may be heated by electrical elements provided in duct 28.  To produce fats of a grade suitable for human consumption the fatty acids present should preferably be below 0.6 per cent, and preliminary experiments are necessary to determine the optimum heating zone temperature and rate of passage.  The solid matter may be separated from the fat by causing it to fall into a separate container at the discharge end of the conveyer, but any residual solid matter may also be separated by centrifugation; this solid matter may be used for animal food.  Air is suitable for use as the heated gas, but the use of mixtures containing more oxygen than is present in air, or of saturated steam, which tends to hydrolyse the fat, should be avoided; super-heated steam, however, is suitable.

Abstract: 839,938. Winding transfer tails on textile bobbins. COLTRTAULDS (CANADA) Ltd. Aug. 13, 1958, No. 25993/58. Class 120(2) and 120(3)  In a ring-spinning machine with a normally stationary spindle and a reciprocating ring-rod, each spindle can be individually raised so that a transfer-tail can be wound on the lower part of the bobbin. In Fig. 1, as a spindle is lifted when a flanged sleeve 12 is raised by a rod 25 worked by a manually-rotated cam 27, a bobbin-supporting flange 17 is brought into the traverse-path of the ring 18. The yarn is then caught in a notch 40, Fig. 4, on the edge of the flange and guided by the shape of the base of the flange to an undercut ring 22 around which and a button 30 it forms a series of loops. When the tail is fully wound, the bobbin is lowered so that the thread is caught in a second notch 42 on the flange to be lead away from the ring. When it is required to make use of the transfer-tail the yarn is severed above a blind hole 38, and the button depressed against a spring to transfer the tail to a part of the button of reduced diameter so that it can be removed as a hank. In starting-up, the yarn passes from drying-rolls 43 to an airejector unit 44, Fig. 8; it is now transferred to an air-ejector 45 which leads to a collecting box through the centre of the bobbin. As the spindle rotates, the yarn is caught in a notch 49 in a bar 50 at the top of the bobbin and broken, whereupon the yarn is transferred to the ring 18. After winding, the yarn is transferred to the ejector 44 until the next winding.
