IPC: B21D7/02
Abstract: 1,025,196. Bending tubes. B. WALTERSCHEID-MULLER, and J. WALTERSCHEID. Oct. 10, 1962 [Oct. 17, 1961], No. 38432/62. Heading B5A. Pipes and tubes of a plastic material are bent without puckering, whilst cold, by subjecting the pipe, during the bending operation, to a compressive force at right angles to the radius of the bend. The tube may be further bent without puckering after the compressive force has been released. As shown, a pipe 4 is bent around a cylindrical body 1 between walls 2 and 3. In one embodiment, the walls are fixed at a distance apart less than the diameter of the unstrained pipe so that the required compressive force is exerted when the tube is forced between the walls. In an alternative embodiment, the upper wall 2 is movable, the pipe being inserted between the walls, the upper wall moved down to compress the pipe, and the pipe bent around the cylinder. A periodic compressive force may be applied by connecting one of the walls to a source of oscillatory motion, e.g. a cam disc (as in Fig. 2, not shown) or an eccentric (see Fig. 3, not shown). In a further embodiment the tube may be bent through angles of 360 degrees or more between helical walls 2a as in Fig. 4 (not shown).

Abstract: 1,231,869. Reflex cameras. NIPPON KOGAKU K. K. Aug.7, 1968, [Aug.11, 1967 (2) ] No.37713/68. Heading G2A. A single lens reflex camera has the following features in combination :- (a) a partially transparent mirror which can move from a position in which it is interposed in the light path, and reflects some of the light into a view-finder, to a position in which it is outside the light path, (b) a second mirror which can move from a position in which it is interposed in the path of light passing through the first mirror and reflects the light on to a photo-sensitive element which is itself outside the light path, to a position which is outside the light path, (c) a shield to prevent light passing between the first mirror and the camera body. As shown in Fig. 1, light entering through the objective 2 falls on a partially transparent inclined mirror 3 which is supported on a plate 4. Plate 4 pivots, via an extension arm 4b, on a fixed shaft 5. Light reflected from mirror 3 passes upwards and is reflected by a pentaprism 8 to a view-finder eye-piece 9. A shield 115 is pivoted anticlockwise by a spring 117 into the position shown in Fig. 1, in which it prevents unwanted light from passing under the lower edge of mirror 3. The centre of plate 4 is cut away to form a window 4a, and light passing through mirror 3 falls on a concave mirror 10, whence it is reflected back to mirror 3 and downwards through a lens system 111-113 to a photo-cell 114 which is disposed out of the light path through objective 2. Mirror 10 is carried by a support 11 which pivots on a shaft 12 itself mounted on arm 4b. At the lower end of support 11 is a transverse part 11a which is connected by a link 16 to a lever 13. A slot 13a in lever 13 is engaged by a pin 15 on arm 4b. Lever 13 itself rotates on a fixed shaft 14. The two mirrors 3 and 10 are thus linked together, and swing upwards together out of the light path, to the position of Fig. 2 (not shown). Owing to the disposition of the levers and pivots of the mirror linkage system, mirror 10 moves with a higher angular velocity than mirror 3. In reaching this position, a pin 128 at the free end of mirror 3 engages the upper end of a lever 118 mounted centrally on a shaft 119, and pivots it anti-clockwise. The lower end of the lever engages a pin 120 on shield 115 and pushes it clockwise about its pivot, against spring 117, so that it is moved out of the light path to a position in which it lies over and covers lens 111. Thus no unwanted reflections from the surface of lens 111 can reach the film during the exposure stage. The mirror system is then pivoted back into the original position of Fig. 1, during which movement the shield 115 also returns to its original position.

Racemic α-DL-glutamic acid can be prepared by crystallizing it (a) from an aqueous solution of racemic glutamic acid maintained within the temperature and pH range formed by connecting the points a-(pH 3À5 and 80‹ C.); b-(pH 2À5 and 70‹ C.); c-(pH 2À5 and 60‹ C.); d-(pH 3À5 and 55‹ C.) ; e-(pH 4À5 and 60‹ C.); f-(pH 4À5 and 70‹ C.); or (b) from an aqueous solution of racemic glutamic acid containing racemic glutamic acid monohydrate in dispersion and maintained within the temperature and pH range formed by connecting the points a-(pH 3À2 and 90‹ C.); b-(pH 1À5 and 85‹ C.); c-(pH 1À5 and 60‹ C.); d-(pH 3À2 and 65‹ C.); e-(pH 5À0 and 60‹ C.); f-(pH 5À0 and 85‹ C.). Optically active enantiomers of #-glutamic acid are prepared by incorporating #-form optically active glutamic acid as seed crystals in an aqueous solution of racemic glutamic acid containing dispersed α-form racemic glutamic acid (as a solid phase) and then crystallizing, when the #-form enantiomer having the same optical activity as the seed crystals separates. The process may be effected in the presence of another amino acid or polypeptide material which inhibits the transition of the α-form DL-glutamic acid into other forms, which would reduce the stability of the supersaturated solution. Specified transition-preventing agents are alanine, lysine, arginine, aspartic acid, histidine, ornithine, norleucine, norvaline, α- aminobutyric acid, citruline, also soybean protein, soybean peptone, gelatin, casein and wheat gluten. The addition of optically-active amino acids, which permits spontaneous crystallization from the solution of optically-active #-form glutamic acid of opposite sign, enables the direct "seeding" with #-glutamic acid to be avoided; alternatively, the two techniques may be combined. The normal temperature range for crystallization is between 40‹ and 90‹ C., preferably 50-70‹ C., and pH 0À5-5À0, preferably about 2.

Abstract: 1,251,791. Winding webs. J. & J. CASH Ltd. 21 Nov., 1968 [23 Aug., 1967], No. 38804/67. Heading B8R. Ribbon winding apparatus 1 comprises a driven face-plate 3 having a chuck 4 for holding a core 9 concentrically against the plate 3, and a guiding face-plate 13 pivotally mounted whereby it may be swung either to an operative position opposite the face-plate 3 for guiding the winding of ribbon on to the core 9, or to an inoperative position clear of the face-plate 3. As shown, the face-plate 3 is mounted on a shaft 5 which is belt-driven from a motor 6 and the chuck 4 is arranged for operation, through a linkage 14, 14a, 15, 15a, by a control lever 12. The guide plate 13 is carried by an arm 16 adjustable along a support shaft 17 for varying the distance between the plates 3, 13 according to the width of the ribbon being wound, whilst the shaft 17 is axially movable so that the guide plate 13 may be brought into light pressure contact with the core 9 during a winding operation, this axial movement being effected by a pneumatic cylinder 20 through a linkage 19, the cylinder being controlled via a valve 21, having an operating switch 21a, from a compressed-air supply 22. The ribbon 10 to be wound passes from a bin 24, through a disentangling mechanism 25 driven, in an opposite direction to ribbon movement, by a belt-drive 29 from motor 6, then through a fault-sensing and measuring arrangement 30, and thence to the core 9 by way of guide 36a. The arrangement 30 comprises a sensing roller 31 spring- loaded to bear against a measuring roller 32; the ribbon 10 passes between the two rollers, and any irregularity, e.g. a knot or a pin in the ribbon, causes the roller 31 to lift and trip a switch in the motor circuit. The roller 32 is associated with a counter 35 which may indicate the length wound or which may be arranged to stop the motor when a predetermined length of ribbon 10 has been wound on the core 9. An interlining paper 40 may be wound on the core 9 together with the ribbon 10, and this paper is supplied from a drum 41 tensioned by a spring-loaded friction disc 42 to prevent over run. An electromagnetic brake 18 carried by the shaft 5 and operating in conjunction with the motor control circuit ensures that the faceplate 3 is stopped immediately the motor 6 is switched off, and thereby prevents overrun of the ribbon 10 at the end of a winding operation.
