Title: Improvements in or relating to textile yarns
IPC: D02G3/36
Filed: 1957-10-08
Abstract: 850,059. Spinning yarns; roller arrangements in textile spinning &c. machines. ANCIENS ETABLISSEMENTS CORDONNIER S. A. Oct. 8, 1957 [Oct. 8, 1956; May 24, 1957], No. 31391/57. Classes 120(2) and 120(3). A composite yarn consisting of a continuous core thread surrounded by discontinuous fibres is made by introducing into the drafting mechanism of a spinning frame (a) a core thread of continuous filaments pretreated so as to be of crimped form when relaxed and straight when taut and (b) a roving of discontinuous fibres in such a manner that the core thread is straightened and the roving entangled therewith to such an extent that the twist of the core is reversed, then contracting the core thread by vapour or hot water treatment so that it contracts upon the fibres entangled therewith. The core thread may be of nylon " stretch " yarn crimped by twisting, setting and untwisting and the fibres may be wool. In the drafting mechanism shown in Fig. 1, a roving 2 is drawn between rollers A and E during passage over tumbler rollers S1, S2, S3, and a crimped thread 1, having twist in excess of that which will exist in the final yarn and in the same direction, is introduced through an eyelet B, passes under pressure rollers A1, A2 and A3 whereby it is uniformly tensioned then between front rollers E: at the exit of rollers E, thread 1 and roving 2 are intertwisted to form yarn F. Modified drafting arrangements reduce interference by the thread with the drafting of the fibres: thus, as shown in Figs. 2, 3, 4, thread 1 passes under rollers A1 but may be diverted (as by means of a roller C) over roller A3 or rollers A2 and A3 before entering the nip of rollers E, and, as shown in Fig. 5, pretensioned thread 1 passes over all the pressure rollers.

Abstract: 466,350. Cutting paper &c. blanks. WOOD, D., and D. W. CONTAINERS, Ltd. Nov. 18, 1935, No. 31899. [Class 31 (i)] [Also in Group XVII] In a machine for making frusto-conical cartons, e.g. milk-bottles or cream-tubs from paper, cardboard, &c., a web of paper is, after printing if desired, led to cutting rollers which form the blanks. The web 10 is drawn from a roll 11 to printing mechanism 16, whence it passes past a tensioning roller 17 to a pair of feed rollers 18. These rollers and other rollers 19. 20 are driven by gearing 21, 22 from a vertical shaft 23 driven by bevel gearing 24 from a main shaft 25 which also drives the printing mechanism 16 through gearing 26. A first pair of cutting rollers 19, 19a with helical blades 27 on the upper roller, make spaced incisions 28 towards two edges of the web. Roller 19 has circumferential recesses 29 containing the blades 27, the web being gripped between the main surfaces of roller 19 and a lower plain roller 19a. A second pair of cutting rollers 20, 20a with curved blades 30 on the upper roller produce transverse cuts 31. With this arrangement the curvature of the front and rear edges of the blank is the same, so that the conical carton will be of greater height on one side than on the other. Alternatively, the blades 30 may be supplemented by blades 32 so that an element 33, Fig. 3, of the web is removed, so that the conical carton will be of even height. The movement of the cutting rollers may be intermittent. The leading end of the blank is gripped by rollers 59, 60 which are of reduced diameter at their ends so that waste material from the outer edges can drop into a shoot 63. The blank passes over a grid 64 on to a hinged platform 65.

Filed: 1973-07-05
Abstract: 1412901 Delay lines STANDARD TELEPHONES & CABLES Ltd 5 July 1973 32002/73 Heading H3U An acoustic delay line comprises a piezoelectric transducer layer 4 which is electrically coupled to the strip conductor 2 of a microstrip transmission line and to a further open-circuit strip conductor 21 having a length such as either effectively to short-circuit the capacitive reactance of the dielectric substrate 1 of the line or both to short-circuit the line capacitive reactance and to tune out the capacitive reactance of the layer 4, the layer being coupled to an acoustic delay medium which provides a folded acoustic path to and from the transducer layer. As shown in Fig. 1, the delay medium is of sapphire or spinel and forms the dielectric 1 for the transmission line comprising the conductor 2 and a ground layer 3. An electrode 20 formed by the end of the strip 21 is also coupled to the layer 4, this strip having a length equal to a quarter wavelength at the working frequency, or longer so as also to tune out the reactance of the layer 4, giving an equivalent circuit containing only the transducer (series) radiation resistance. The strip 21 may be wider than the strip 2 or of varying width, and one or more further open-circuited strip lines (22, Fig. 3, not shown) may be added. A wider frequency response and a filter characteristic may thus be achieved. In other embodiments the transmission line dielectric 31, Fig. 4, is of alumina while the acoustic delay medium is a body 35 of sapphire or spinel carrying a transducer layer 36 and electrodes 37, 38 extending to conductors 39, 40. The body 35 is attached to the transmission line by adhesive 41, with the conductors 39, 40 in contact with strip line conductors 33, 34.
