Abstract: 1,135,388. Photographic printing. AGFAGEVAERT A.G. Dec.3, 1965 [Dec.4, 1964J, No. 51409/65. Headings G2A and G2C. After developing a number of film strips, they are joined together and passed through a printers where the operations are controlled automatically by means which scan or detect data on the film. Fig. 4 is a flow diagram showing the sequence of operations. At box 11 the end of a strip of undeveloped film projecting from its cassette receives perforations (6, Fig.l, not shown) forming a reference number in binary code. At box 12 the film is developed and dried in the normal way. At box 13 the films are sorted, and films of like size are joined together. At the same time, a notch (10, Fig.3, not shown) is made at the top edge of the film in a predetermined position with respect to each film frame, and another notch (7) at the bottom edge in a position corresponding to the series of perforations (6). Box 14 is the printing stage. Sensing means respond to the upper notch (10) to stop the film feed at the correct position and initiate the printing. Further sensing means respond to the lower notch (7) to scan the binary code perforations (6), and decode it so that a machine stamps the same number in ordinary numerals on the back of each print. The exposed papers then pass to box 17, where they are developed, and box 18, where quality inspection and checking is carried out. If a print is unsatisfactory, the correction details are stamped on a slip, and film and print returned along paths 19, 20 to box 14 for reprinting Satisfactory prints pass on to box 21, where they are separated by cutting. The film negatives from box 14, together with envelopes stamped with the reference number at box 11, both pass directly to box 22, where the films are cut into strips and put into the envelopes. Finally the prints are checked at box 23 and also put into the corresponding envelopes.

A spring 48 disposed within each support and connected to the front end of the sleeve by a link 57 biases the seat to its rearmost position. The helical spring 48 may be replaced by an elastomeric band. A backrest 22 includes a pair of laterally spaced sockets 76 for mounting the backrest on the supports 72 for limited tilting movement. Each socket 76 may be provided with a connector 74 to which a link 78 slidably mounted within the support is pivoted. A spring 82, engaging a flange 78a on the link, biases the link to its lowermost position in the support. The connector may be replaced by one or more leaf-springs (92) Fig. 8 (not shown) moulded into a flexible plastics or rubber casing secured to the support. In another embodiment Figs. 9A and 9B (not shown), the connector (100) is pivotally connected to the upper end of the back support and is provided with an off-centre extension which engages a resiliently deformable body (108) disposed between the extension and the internal wall of the support when the backrest is tilted. In a further embodiment Fig. 10 (not shown) a rubber rod (110) is secured to both the connector and the support. The integral seat and back supports may be Z-shaped, the upper limb of the Z defining an armrest. The seat may be supported on a central pedestal. Specifications 1501766 and 1501767 are referred to.

Abstract: 1280329 Tape transport systems MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 29 Oct 1969 [29 Oct 1968 (2)] 52958/69 Heading G5R In a cassette machine where the ends of the tape are attached to the hubs 16, 17 of the supply and take-up reels, cessation of tape movement causes the drive to the tape and take-up reel to be disengaged. When button 94 is pushed into the position shown, pinch roller 28 on arm 80 is swung into its operative position and an L-shaped lever 46 rotates anticlockwise until pin 78 passes behind shoulder (106). The lever carries a shaft 54 which engages reel carrier 14, the shaft being rotated through clutch 62 by means of a motor 34 driving a pulley 60 through belt 36. A further clutch 74 operated from shaft 54 tends to rotate arm 70 which follows a cam 40 on flywheel 32. When the tape stops, shaft 54 ceases to rotate so that the arm 70 does not follow the cam 40, (Fig. 4, not shown), whereupon the projection 42 strikes the arm, thereby displacing it, Fig. 1 (not shown), so that the arm 46 rotates about its pivot to remove the drive to the carrier 14 and release the slide 88, which, in returning to its off position, displaces the arm 80 to remove the pressure roller 28. The striking of the elements 42, 44 may serve as an end of tape warning and the operation of the device may be arranged to cause tape reversal.

Abstract: 1293366 Knitting-machines JUMBERCA SA 29 Oct 1969 [29 Oct 1968 30 July 1969] 53084/69 Heading D1C Pattern drums, e.g. 1 of a circular machine are rotated by toothed wheels 3a, 3b turned by selectable cams 7 which rotate past the wheels. The drum may be rotated in either direction and by one or two unit steps by appropriate selection of the cams. The wheels 3a, 3b are mounted on co-axial shafts 21, 22 respectively so as to rotate the drum-pinion 17 by pinions 18, and 19 and 20 respectively. The selecting unit 25 which rotates past the wheel carries two pairs of cams, one pair opposite each wheel. The cams are selected by projecting cams 28 from a fixed unit 27 at the dictates, of a pattern chain. One cam of the pair carries one projection 8; the other, two 8, 8b. Thus selection of the former rotates the wheel one step, while selection of both rotates the. wheel two steps. Alternatively the drum may be rotated by providing cams on both sides of a single wheel, Fig. 8 (not shown) or two superimposed appropriately cut wheels (Fig. 10, not shown). In an alternative embodiment (Fig. 12, not shown.) the wheel (103) is rotated by selectively projected pivotable cams (207, 208).

Dense'hard metal oxides are made by heating a composition containing a compound, or mixture of compounds, which on decomposition yields one or more of beryllia, thoria, urania and iron oxide, to a temperature of 300-1000‹ C. under a pressure of 2,000-50,000 psi to cause a molecular decomposition. The oxideforming compounds, prior to heating under pressure, can be mixed with metal or non- metallic fibres, rock, sand and also metal powder so as to produce a cermet. The oxideforming compound may be a carbonate, bicarbonate, sulphate, nitrate, hydroxide or hydrated hydroxide; the use of iron carbonate and ammonium diuranate is exemplified. The composition can be formed under pressure in a die with heating taking place whilst the composition is still in the die. The composition can be cycled through the temperature at least twice. In the example the composition is heated by induction using a graphite die which functions both as a susceptor and a pressing component. The composition can be hot pressed in an atmosphere of air, nitrogen or argon. The pressure can be applied by hammer blows or a continuous pressure transmitting device. The hot-pressed oxide product can be reheated, e.g. to 750‹ to 1500‹ C. with or without pressure.
