Abstract: 1352624 Crimping yarns SNAM PROGETTI SpA 18 Oct 1971 [17 Oct 1970] 48440/71 Heading D1F In a crimping process, a strand as may be formed by combining multifilamentary yarns of synthetic e.g. nylon, filaments is fully drawn, crimped in a compression chamber and subjected to a vapour e.g. steam, or gas-vapour mixture at a temperature of 70-150‹C during or subsequent thereto and finally subjected to a controlled extension to reduce or eliminate "visible" crimp. The vapour may be saturated or superheated, provided from an outside source or generated by vapourising (e.g. by means of a hot gas) a liquid carried by the strand. As shown, yarns supplied from bobbins 1, 2, 3 pass through a collecting ring 4 to form a strand which is drawn by rollers 5 and 7 whilst passing over a heated plate 6. Drawn strand is fed by rollers 8 to a chamber 9 wherein it is crimped by compression against a pressure member 10, and a chamber 11 to which vapour is supplied, thence through tensioners 12, around advancing rollers 13, 14 through a drawing zone defined between rollers 15 and 17 and wherein it is heated by plate 16 before collection on a bobbin 18. The strand product may have a crimp frequency of 2-8 per centimeter, a "rate" (as defined in the description) of 5-25% and may be produced from strands of initial denier of 2600-7800 intended for carpet weaving.

Abstract: 1329260 Making envelopes WINKLER & DUNNEBIER MASCHINENFABRIK UND EISENGIESSEREI KG 13 Oct 1970 [13 Oct 1969] 48618/70 Heading B5D The closure flaps of envelopes or flat bags may be folded to the front or rear of the envelope or folded and re-opened by means of apparatus including three suction cylinders 11, 12, 13 having associated therewith folding and opening devices and elements for controlling the suction applied by the cylinders. The suction cylinders 11, 12, 13 are provided respectively with rows of suction apertures 31, 37, 40 whose suction is timed through arcuate control slats 33, 39, 42 the effective lengths of which are variable by means of known control slides to determine where the envelopes will be delivered. The first suction cylinder 11 comprises a middle part (22) driven in the direction of arrow M and side parts (23) driven by contact with cylinder 13 in the direction of arrows. The closure flaps 4 of envelopes 1 are folded to the rear of the envelopes by the combined action of a folding pocket 9, a folding roller 10 and a suction cylinder 7 of the envelope making machine from which it is transferred to the first suction cylinder 11. If rear-folded closure flaps are required, the envelope is then passed, still folded, via cylinders 12 and 13 and delivery discs 18 to a delivery table 20, as shown. If re-opened envelopes are required the envelope is passed round cylinder 11 by the middle part (22), to a stop abutment 14 where the flap is opened by an air opener 15 and the suction to the cylinder cut off. The envelope is then counter rotated by the side parts (23) of the first cylinder 11 and the third cylinder 13 to discs 18 and table 20. If front-folded flaps are required, after reopening of the flap as above, the envelope is passed via the second cylinder to a folding pocket 16 from which it is lifted past a folding roller 17 by the third cylinder 13. Alternatively, the envelope may be supplied unfolded by the envelope-making machine and the closure flap is folded to the front by passage round cylinders 11 and 12 into the folding pocket 16 from which it is lifted past the folding roller 17 by the cylinder 13.
Patent GB-487912-A (GB)
Abstract: 487,912. Anti-aircraft gunnery practice. CONTRAVES AKT.-GES. May 31, 1937, No. 15135. Convention date, Feb. 9. [Class 119] The error in anti-aircraft gunnery practice aiming is indicated as follows. Two theodolites or their equivalents, 4, 5, Fig. 1, are kept directed on the aircraft 3, and the training and elevation of these theodolites are transmitted to a central station 8 by lines 6, 7. The training and elevation of the gun 1 are also transmitted to the central station 8 by a line 9, but a device 10 interposed in that line delays the transmission by a time corresponding to the time of flight of the projectile to a position G, Fig. 2, on the trajectory a a, the device 10 being set from the station 8 by the mechanical transmission 11, 12. From these data, the central station calculates the distances from the aircraft F, Fig. 2, to points P1, P2 on the trajectory a a or P3, P4 on the tangent to the trajectory at equal distances from the point G. If these distances from the aircraft are not equal, an adjustment of the device 10 is made under control from the station 8 by means of a line 13 and a servomotor 14 until these distances are equal. Then the point G is the point of the trajectory nearest the aircraft F and the distance Z from G to F is the aiming error. The error in aim can be read off or registered on an instrument 15.

Abstract: 1282565 Coils EMI Ltd 17 Oct 1969 [18 Oct 1968] 49420/68 Heading H1P [Also in Division C7] A metallic pattern, e.g. conductors 4, 5 for forming a printed scanning coil for a vidicon, is formed on an insulating layer 3 by plating a metal (or alloy) on to portions of a metallic matrix 1, electronegative with respect to plating metal and connected as cathode in a plating bath, which portions are exposed by a mask of plating resist 2, e.g. borosilicate glass in the configuration of the pattern, applying to the plated matrix an insulating layer 3 coated with a tacky adhesive of peel strength greater than the bond strength between the plated and matrix metals, and removing the layer with the metallic pattern adhering thereto by peeling from the matrix. The pattern metal may be Cu or Ni-Cr and the matrix metal stainless steel or a metal having a Cr layer, highly polished to give weak bond strength. After plating, the surface of the pattern metal may be treated, e.g. oxidized or roughened, to improve bonding to the tacky adhesive. Prior to plating with the pattern metal, the matrix layer pattern may be plated with a further metallic such as of solder, e.g. 60 Sn-40 Pb alloy, which will form a coating over the pattern metal when the layer 3 is peeled from the matrix. The matrix may be flat or wound around a plastic drum (as shown) made by fixing discs 6 provided with apertures 8 with stub axles 7 at each end of a hollow cylinder; the drum may be arranged in the plating bath, e.g. with an arcuate Cu anode, for rotation. To form a printed scanning coil, the layer 3 with conductors 4, 5 adhering thereto may be wound into a cylinder and heated to cure the adhesive.

As shown in Fig. 1 the means exerting compressive force comprise a plurality of springs 18 extending between the ring gear and a layer 17 of deformable refractory material such as asbestos surrounding the disc and held in position by one or more collars 40. In the alternative embodiment shown in Fig. 4, the radial compression of the disc is effected by means of compressed air filling the annular chamber 20 between the ring gear 2 and the periphery of the disc. The air is supplied by the incoming air stream 11 via a central disc opening 15 and a plurality of radially extending passages 21. Lateral fluid tightness of the chamber 20 is achieved through toroidal shaped gaskets each of which is constituted by a helical spring 22 around which a flexible metal sheet is wound, the opposite edges (24, 25, Fig. 6) of the sheets defining circular slits 26 facing the chamber interior. A tie-rod 31 extending through the central opening 15 and serving to interconnect an outer cover 32 and an internal partition or frame member 33 is cooled by air passing through internal passages 36 and 37 in the rod.  In a modified embodiment (Fig. 7, not shown) lateral sealing of the annular chamber between the ring gear and the ceramic disc is effected by annular rings (27) of square or rectangular section urged into sealing contact with flanges on the ring gear and with the disc periphery by means of radially and axially directed springs (28, 29).
