Abstract: 1335969 Pile fabrics; opening tows NORWOOD MILLS Inc 29 Dec 1970 [17 March 1970] 61406/70 Headings D1F and D1K A method of producing a glued pile fabric, comprises taking a plurality of webs 70', 72'- 82', 84' of monofilamentary tow from different sources and forming a multiply batt 110 which is fed to a cutting station where it is cut transversely to form strips of cut fibres, which are advanced into an accumulator chamber to form a mass of parallel cut fibres which is brought into contact with an adhesive coated backing 126. The sources of tow may comprise a plurality of rolls 70, 72-82, 84 on a creel 86, or a number of machines Fig. 1, for taking the tow from a bale 12 and opening it, operating in parallel. The batt 110 is fed intermittently to the cutting station by belts 108 and 114 where it is initially clamped by a pressure plate 220 against a guide plate 216 and by a pusher 280 against backstop 290. A rapidly moving band cutter 226 then moves forward (Fig. 5, not shown) to slice off the strip of fibres, and backstop 290 moves towards the blade (230), pushing pusher 280 against a biassing spring to bring any remaining uncut fibres over the edge of the blade, (Fig. 6, not shown). Then the backstop moves back again to allow the strip of cut fibres to expand (Fig. 7, not shown) and up out of the path of the fibres as they are advanced into accumulator chamber 219 by pusher 280. The mass of cut fibres passes out of chamber 219 onto a belt 140, and backing material 126 is fed from above, under an adhesive hopper 136 onto the top of the cut fibres. The top and bottom plates of 284, 218 of the accumulator chamber may be earthed (Fig. 3, not shown). In an alternative embodiment, the backing fabric may be supplied from below the level of the accumulator chamber and glued to the bottom of the mass of cut fibres (Fig. 12). The top of the accumulator chamber (502) Fig. 16 (not shown) may be pivotally supported and raised at the front end by pneumatic pistons before the strip of cut fibres is pushed in. The backing material may be osnaburg cotton sheet, polyester spun bonded sheet or acetate tricot knitted material. The pile yarn is crimped polyester material of denier from 3 to 6, and the adhesive may be an acrylic adhesive. The height of the pile is between one half and three inches. Treating yarns. Crimped synthetic yarns are drawn from a bale 12, Fig. I in a band 14 over guide bars 16 and 18 and spread by passing them through a series of spreaders 20, 36, 42 and 48 each consisting of a narrow space through which the yarn is passed and air is blown. An earthing bar 34 extends across the width of the tow, and the spread tow 50 is taken up on a roll 54 rotated by a belt 56.

Title: Thyristor and method of making the thyristor
IPC: H01L21/332
Filed: 1979-04-24
Abstract: A thyristor has four zones 32-38 of alternating conductivity type including a top-most N<+> emitter zone and a P base zone situated below the emitter zone and also having a top surface continuous with the top surface of the emitter zone. The base and emitter zones form a turn-on junction 40 at their major interfaces and a turn-on line 42 at their major vertical interfaces. A control electrode 62 is in contact with the base zone 34. A cathode electrode 60 for the thyristor overlies and is in contact with the emitter zone at a body-top-surface 22, and also contacts the base zone at discrete points or/areas which form a line of emitter shorts 46, which line is spaced from the turn-on line at a substantially uniform distance. An "alignment" region 50 of N<+> conductivity type is sunk into a surface- base-portion 44. Its upper surface coincides with the body-top surface; it is spaced from the emitter zone 32 by part of the surface- base-portion 44. Its one vertical wall which is more remote from the turn-on-line 42, herein termed the "alignment edge" 62, is spaced from the turn-on-line by a substantially uniform distance. The control electrode 62 extends on to a part of the alignment region 50. The thyristor provides uniform turn-on voltage along the turn-on line 42. <IMAGE>

Title: Crop roll forming machines and drive systems therefor
IPC: A01F15/08
Filed: 1980-03-26
Abstract: A crop roll forming machine has a bale forming means in the form of an upper apron 46 which can be driven by drive means in a normal first direction of rotation or in a second direction of rotation Y opposite to the first direction. Control means mounted on a frame of the machine are movable between a first position and a second position for cooperative interaction with the drive means and the upper apron 46 to selectively cause the upper apron 46 to cease being driven in the first direction and cause it to be driven in the opposing second direction Y when the control means is moved from the first position to the second position. Reversal of the direction of movement of the upper apron 46 causes a completed crop roll R to be ejected rearwardly from the machine onto the ground. The said control means is actuated by raising the tailgate 20. <IMAGE>
