Title: Photographic Roll Printing Machine.
IPC: G03B27/58
Filed: 1967-09-26
Abstract: 1,165, 592. Photographic roll printing machine. AGFA-GEVAERT A. G. Sept. 26, 1967 [Sept. 29, 1966], No. 43766/67. Heading G2A. A photographic roll printing machine for printing light-sensitive material in strip form, in which the strip material being printed is intermittently advanced in a stepwise manner, has a single manual control knob 2 for adjusting the length of the advancing step of strip material and for simultaneously adjusting the mask to control the border width of pictures to be printed, the control knob being permanently connected to the advancing step adjustment and being disconnectable from the adjustment for the border width so that the step length and border width may be varied with respect to each other. In Fig. 1, control knob 2 is connected via hollow shaft 3, pinions 7 and 9 and dog clutch 11, 12 to a shaft carrying a gear-wheel 17 which adjusts the mask for varying the border width. Knob 2 is also connected via hollow shaft 3 and pinions 7 and 8 to an adjustment 20 for varying the step length. Knob 2 as shown is in a locked position, the locking pin 32 being obstructed. When knob 2 is pushed in, after freeing pawl 29, locking pin 32 is disengaged and the hollow shaft 3 slides along shaft 12 and moves the switching fork 14 against spring 25 to lift member 16a against spring 13 and thus to disengage the dog clutch 11, 12 and to disconnect the border width adjustment. Pushing knob 2 in also frees the recessed disc 22 from pin 23 since shaft 21 does not move axially, and knob 2 can then be rotated to vary the step length adjustment 20 without altering the border width. To alter the border width and step length simultaneously but retaining their relative adjustment, the knob 2 is pulled out, locking pin 32 again being disengaged, the shaft 21 pulling recessed disc 26 free from pin 27 and enabling knob 2 to rotate and operate both the border width adjustment 17 and the step length adjustment 20. The recessed discs may be replaced by spring- actuated friction couplings to obtain continuously graduated adjustments.

Abstract: 1522420 Colour television receivers MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 29 Oct 1976 45184/76 Heading H4F Colour difference signals derived from a received video signal are modified, in order to reduce luminance errors in a reproduced colour, by reducing the amount by which the signal exceeds a threshold signal which is proportional to the luminance signal. In one arrangement, Fig. 8, colour difference signal demodulators 4-6 feed red, green and blue matrix circuits 7-9 via resistors 45-43. The luminance signal Y is fed (34) to a circuit 15 which produces a corresponding threshold signal at diode 39 so that, when the R-Y signal exceeds the threshold, resistors 45, 42 act as a voltage divider. In addition the colour difference signals are summed via resistors 20-22 to provide a d.c. reference level at diodes 37, 38. When the B-Y or G-Y signal exceeds the reference level resistors 43, 40 or 44, 41 act as voltage dividers. The dividers ensure that, above the threshold level, the excess of the colour difference signal is reduced prior to reaching the respective matrix.

Filed: 1966-10-11
Abstract: 1,136,152. Magnetic data storage apparatus. STANDARD TELEPHONES & CABLES Ltd. 11 Oct., 1966, No. 45384/66. Heading H3B. A magnetic store (Fig. 3) consists of a low reluctance magnetic plate 1, e.g. of ferrite, having projections 4 defining spaces 5 which have a larger area than the projections. Parallel to plate 1 is a film 8 of anisotropic magnetic material, which may be supported by a substrate 9 and is preferably spaced from the projections 4 by a non-magnetic layer 10. Row and column conductors 7 and 6 consist of pairs of lines connected in parallel so as to surround spaces 5. An alternative construction of the ferrite plate is shown in Fig. 1a. For read-out a current pulse is passed through word conductor 7 to rotate the magnetization in the portions of film 8 which overlie spaces 5 associated with the selected conductor into the hard direction, inducing an output voltage in conductor 6, or in a separate sense conductor. Information is written, or rewritten, during the same word pulse by supplying a bit pulse of appropriate polarity to each conductor 6. Read out may be made non-destructive by providing short-circuited turns around the projections 4 which lie on each side of a space 5 along each row. Alternatively the tops of these projections may each be provided with a conducting layer. Two alternative methods of construction of the device are described. In the first, the conductors are placed in position and the spaces between the projections on the ferrite plate are filled with potting compound. The surface is then polished and the anisotropic film is deposited on to it. The second method consists in depositing the anisotropic material on a substrate, depositing the conductors on the film, depositing ferrite layers to form the projections and then depositing a thicker layer of ferrite to form the base-plate.

Abstract: 1,048,581. Photographic colour printing. PAVELLE Ltd. Jan. 17, 1963 [Dec.21, 1961], No. 45873/61. Headings G2A and G2C. A method of making a colour print from a negative or transparency comprises first making a test print by passing light through the negative and then through a test chart consisting of a series of filters of graded density in each of the three component colours, and so ascertaining the necessary exposure time for each of the three colours. Figs. 1 and 2 show the method utilized in a contact printing arrangement, formed as a light-proof box divided into two compartments 1, 5 by a vertical wall 3, which has a slot 4 about half way up. Compartment 1 houses a lamp 2, and compartment 5 is itself divided into three horizontal sub-compartments 6, 7, 8. Sub-compartments 7 and 8 are separated by a negative carrier 13 which can be slid into position from outside the end wall 14. The upper sub-compartment 8 has a glass plate 11 for its top surface, over which a hinged flap 12 can close. Initially, the negative 24 is mounted on its carrier 13 in the position shown in Fig. 1. On the glass plate 11 is laid a test chart 25 and a sheet of light-sensitive printing paper 26, the flap then being closed down. The test chart (or colour wedge) 25 comprises a plate counting three series of filters, one series for each of the component colours, each series being of graded density. In front of slot 4 is mounted a filter slide 17, which has four slots. The first slot 20 is open, the second slot 21 carries a blue filter, the third slot 22, of smaller width, carries a green filter, and the fourth slot 23, narrower still, carries a red filter. The different sizes are to balance the exposure times. Slide 17 is positioned so that the open slot 20 is opposite slot 4. An exposure of predetermined duration is made, the interior walls of sub-compartment 7 being of a light-diffusing nature. The paper 26 is removed and developed, and exposure times for each colour read off corresponding to those filters of each series which have just yielded a positive image. These exposure times are included on the test chart as a calibrated scale in the form of translucent numbers. The negative is now removed, and re-positioned on plate 11, covered by a new sheet of printing paper, in the normal contact-printing arrangement. The filter slide is moved along until the blue filter 21 is over slot 4, and an exposure made of duration determined from the test chart exposure. Exposures are similarly made through the green filter 22 and the red filter 23. The exposures may be controlled by microswitches and time switches actuated by the movement of the filter slide. Figures 3 and 4 (not shown) are of a projection printer adapted for the same method. The method described above is suitable for additive colour printing, but can be modified for subtractive colour printing by replacing the colour filter slide by a colour correction filter unit comprising continuous wedge filters in cyan, yellow and magenta.

Abstract: Benzene hydrocarbons are alkylated by reaction with an alkylating agent at elevated temperature in the presence as catalyst of primary aluminium phosphate on an acidic or neutral support, e.g. aluminium phosphate, boron phosphate, silicon carbide, silicic acid or an acid silicate such as montmorillonite which may be acid activated or a synthetic aluminium or magnesium silicate cracking catalyst.  The alkylating agent may be ethylene, propylene or butenes in amounts of 20-120 mols. per 100 mols. of benzene hydrocarbon, reaction being effected at 200-320 DEG  C. and 20-100 atmospheres preferably in the liquid phase with a throughput to form 0.3-2 kg. of alkylate per litre of reaction space per hour.  Some of the reaction product may be recycled to dilute the olefin feed.  The catalyst is stated to be ineffective for transalkylation and if desired the product may be passed over an active transalkylation catalyst, e.g. tungstic acid.ALSO:An alkylation catalyst comprises primary aluminium phosphate on an acidic or neutral support, e.g. aluminium phosphate, boron phosphate, silicon carbide, silicic acid, an acid silicate such as montmorillonite which may be acid activated or a synthetic aluminium or magnesium silicate cracking catalyst.  The support is impregnated with a solution of the primary aluminium phosphate to introduce 2-30% of the catalyst and is then dried and heated at 400-500  DEG C.  It may be formed into pills or spheres having a size of 2-10 mm.  Regeneration is effected by roasting in air at 400-600 DEG C.

Abstract: 951,041. Tube bender. FMC. CORPORATION. Dec. 6, 1962 [Dec. 18, 1961], No. 46063/62. Heading B3E. A tube bending machine comprises first and second dies rotatable about a common axis and, by means of an hydraulic cylinder, relatively movable along said axis towards and away from one another, the dies being shaped to cooperate in forming a tube-receiving die cavity, when the dies are adjacent one another, and to grip a length of tube therebetween, means for rotating said dies about said axis to bend said length of tube, and a mandrel arranged to project into said tube to prevent collapsing of the tube wall. A length of tubing W to be bent is placed in a die cavity 28 formed on the upper surface of a lower die D rotatable about a vertical axis in the machine frame 10. The cavity 28 is of quarter-round section for about 90 degrees around the axis of rotation of the die, opening into a part of semicircular section, a socket cavity 29 of which engages the expanded head part 30a of the tube W. An upper die E formed on its lower face with a cavity 28a similar to the cavity 28 is then moved down, on guide rods 32 extending from the lower die D, by an hydraulic cylinder F carried at the upper ends of the rods 32. The end of the tube W is thus gripped between the dies D and E. A mandrel M is then moved part way into the tube W by an hydraulic cylinder G. A pusher P, coaxial with the mandrel M, is then advanced by an hydraulic cylinder H to engage the end of the tube W and start its bending. As the resistance to bending increases, pressure fluid is directed to an hydraulic cylinder C which pulls a chain 49 passing round a sprocket 26 on the die D, thus assisting the pusher P to rotate the dies. A spring S serves to return the dies.
