Electrical screening members for transformers and other electrical apparatus are formed using an insulating tape 38 (Fig. 10), having separate conducting areas 39 coated thereon. The conducting areas may be produced from metal or carbon by printing or vapour deposition and may be surrounded by conducting areas of higher resistance. The gaps may be half the length of the conducting areas they separate. A screening member may be formed by wrapping a screening tape and possibly an insulating tape(s) round a pressboard support (Fig. 2, not shown). Alternatively the screening tape may have both edges folded inwards and may be enclosed in an insulating wrapping (44), (Fig. 7, not shown). Stiffening may be provided by a further tape or pressboard member (41), (50) which may be inside (Fig. 6, not shown), or outside (Fig. 8, not shown), the insulating wrapping (44). Some or all of the tapes and stiffeners may be of absorbent material such as pressboard or paper or the tapes may be of plastics foil. A shielding ring may be made by winding one or more tapes (48), (Fig. 9, not shown), together with insulating tape (50) to form a ring at the end of a winding (52). The conducting areas adjacent the ends of the screening tape may be shortened and may be of high resistance. The screening tape may be of crepe form.

The adjusted chain is cooled by a blower 136.  The element sensing device consists of a first sprocket 82 mounted on arm 94 pivoted on shaft 96, any such pivotal motion being detected by transducer 114, and a second sprocket 84 on a fixed shaft, both sprockets having the same number of teeth and both engaging between the fastener elements. Sprockets 82, 84 rotate in synchronism and any variation in element spacing causes pivoting of arm 94 and the transmission of electric signals from transducer 114 for recording on endless tape 128 by head 130. After a pre-determined delay, the signals are detected by reading head 134 to control the variable speed motor mechanism 126 driving rollers 124. The stringer tapes are preferably of heatshrinkable thermoplastics material, such as polyester or nylon.

Abstract: 1491697 Ferrocyanide blue DEUTSCHE GOLD-UND SILBER-SCHEIDEANSTALT 10 Dec 1974 [8 Nov 1974] 53320/74 Heading CIA Ferrocyanide blue (ferric ferrocyanide; Berlin blue) is produced by simultaneously introducing into water an aqueous solution containing ferrocyanide ions and an aqueous ferrous salt solution, provision being made for optimum mixing (i.e. stirring with an intensity which is not high enough to damage the precipitated product) during precipitation, after which the precipitate formed (white paste; ferrous ferrocyanide; Berline white) is aged in the reaction medium itself at elevated temperature in the presence of salts produced during the reaction and is subsequently converted into ferrocyanide blue by oxidation in acid medium. Either the ferrocyanide or the ferrous solution may be used in slight excess in order to adjust colouring strength. The ferrocyanide used may be sodium or calcium ferrocyanide. A calcium ferrocyanide solution which also contains about I mole of calcium chloride per mole of calcium ferrocyanide may be used. Use of potassium ferrocyanide results in a higher quality product containing potassium ions. When other ferrocyanides are used, including mixtures of potassium and sodium ferrocyanides, a potassium or ammonium salt may be added during or after precipitation in order to improve the colour properties of the pigment. The ferrous salt solution may be a pickling solution. Ageing of the precipitate may take place under elevated pressure.

Abstract: 1364101 Coiling helices MORGAN CONSTRUCTION CO 23 Nov 1971 [9 Dec 1970] 54349/71 Heading B3E Rod or bar from a rolling mill or other elongated product is coiled by laying means rotatable about a mandrel, the leading part of the product being coiled loosely about the mandrel and then held against the mandrel while the laying speed is increased to form tight turns, the mandrel being reciprocated to form the coil and eventually withdrawn from the completed coil. In the Figure, the mandrel 12 protrudes through a platen 62 resting on a flange 66 on the mandrel. The laying head comprises a rotatable tube 14 and laying pipe 30a, 30b, 30c, 30d supported by skirt 34 attached to tube 14 by spider 36. The top of the coil is defined by two plates 55a, 55b retractable by jacks 51a. Two arcuate grippers 68a, 68b (see also Fig. 2, not shown) are rotatable on the platen by torque motors 72 so as to abut the mandrel face or be spaced from it. The mandrel is reciprocable on a guide system 42, 46 by jack 52. In operation, the presence of an advancing length of product is sensed and causes rotation of the laying head at a speed to form a few loose coils round the mandrel during a time delay, after which the grippers 68a, 68b are actuated to hold those coils against the mandrel and the laying head speed is increased to produce a predetermined tension in the product and form tight coils on the mandrel. Reciprocation of the mandrel to form layered coils is also initiated, and controlled by limit switches. The grippers are released before the first coils are overwound. When the end of the product length passes the sensor, a time delay is allowed to finish coiling, then the mandrel is lowered so that the platen rests on supports 74, and further lowered after retraction of plates 55a, 55b, to leave the coil free for removal.

Title: Improvements in single lens reflex cameras having interchangeable objective lenses
IPC: G03B7/20
Filed: 1965-12-22
Abstract: 1,099,172. Single lens reflex cameras. NIPPON KOGAKU K. K. Dec. 22, 1965 [Dec. 25, 1964; Dec.29, 1964], No.54372/65. Heading G2A. A single lens reflex camera having interchangeable lenses has a through-the-lens light meter, in circuit with which is a variable resistance; the resistance is altered when one lens is replaced by another, so that the reading of the galvanometer at maximum lens aperture is always the same, even though different lenses may have different maximum apertures. In Fig.1 the light passing through the objective L is reflected from a mirror M to fall on a photo-conductive cell D and a focusing plate P. Rotatably attached to a fixed cylinder 1 forming part of the camera body is a ring 3 for calculating the exposure, the ring having an arcuate groove (3a, Fig. 4 not shown) with a radial extension (3b). An upper flange (3c, Fig. 5 not shown) of ring 3 carries an aperture ratio scale (3d). A thin strip 4 of insulation is cemented round ring 3, and on this is formed a resistance strip 5 (which is the "variable resistance" of the invention) attached at one end to a conductor 6. Also rotatably mounted on cylinder 1 is a ring 7, having an arcuate slot 7a in its lower portion, and carrying shutter speed markings (7b) on its periphery. Attached to ring 7 is a spring strip 11 making contact with resistance 5. Attached to the camera body is a fixed spring strip 13 making contact with conductor 6. Strips 11 and 13 are connected to either side of a galvanometer (G, Fig.6 not shown). A ring 15 is also mounted on the camera body, the ring having an outer projection 15a, and an internal arrangement of stop grooves (15b, Fig. 4 not shown). A Y-shaped plate (17) lies within a groove (3a) and extension (3b), a pin (18) engaging in one of the grooves (15b) to lock rings 3 and 15 from turning relative to each other except when plate 17 is pressed inwards to unlock the coupling. When an objective of, for example, F 1À4 is mounted on the camera, the index 1À4 on scale (3d) is set against the film sensitivity scale (e.g. ASA 100) on ring 15. Ring 7 and a stop index ring L 1  on the objective L are both rotated until an indicator needle connected to the galvanometer is brought to a fixed mark. Rotation of ring 7 causes contact 11 to move on resistor 5, and rotation of ring L 1  causes a stop member S mounted on it to engage the projection 15a and hence rotate resistor 5 with respect to contact strip 11. The exposure value is measured with the aperture blades fully open. When the shutter release is pressed, the blades are released from their fully open position to the position indicated on the index ring L 1 , and the exposure made. When an objective of F 2 is mounted, ring 3 is adjusted accordingly.
