Title: Improvements in or relating to Photographic Type-Composing.
Inventor: MOYROUD LOUIS MARIUS
IPC: B41B17/10
Filed: 1966-02-22
Abstract: 1,180,913. Photographic type-composing apparatus. INTERNATIONAL PHOTON CORP. 22 Feb., 1967 [22 Feb., 1966], No. 7752/66. Heading B6W. The transcription unit of a photographic type-composing machine has an optical system for projecting the latent image of a projection area 3 to a number of sections 8, 10, 12, 14 of a line under composition on film 6. Optical shutters 28, 30, 42, 50, e.g. of the " electrooptical " type, each obstruct an optical path 21, 23, 25, 27 from area 3 to a unique section of the line and are controlled by a switching circuit to open the shutters in turn, which circuit is served by a character width computer. Projection area 3 may be the face of a cathoderay tube producing short lines (length " d ") of characters to be projected in any of the positions 8, 10, 12 and 14 on films 6. The characters may be produced by generating them rapidly one after the other from a position 33 to a position 31. Alternatively, the characters may be in the form of transparencies on a continuously rotating matrix drum (see U.K. Specification 1,076,181). Each character to be reproduced has its width entered in a width accumulator. When a character causes the accumulator to run over the maximum segment width, i.e. of a segment such as 8, this character produces a " carry " pulse, closing shutter 28 and opening shutter 30, with a simultaneous return of character representation from position 31 to position 33 (see U.K. Specifications 1,076,181 and 1,093,856). The cathode-ray tube or character matrix may also be associated with two lenses 102, 106 and optical wedges 100 and 104, Fig. 6, such that a first line segment produced at location 80 and a second at location 81 will reach film 6 on a common base line 108. In a further embodiment each optical path may be split into parallel paths, each containing an optical shutter and an optical system of different magnification to provide various magnifications of the projected image.

Filed: 1942-06-08
Abstract: 564,733. Abrasive-coated sheets. BEHR-MANNING CORPORATION. June 8, 1942, No. 7808. Convention date, June 9, 1941. [Class 60] In making abrasive-coated sheet material comprising abrasive grains adhesively secured to a backing, the adhesive coat is at least partly set to anchor the grains, a sizing coat of adhesive is applied over the grains, and the abrasive-coated sheet is maintained with its grain surface facing downwardly while the adhesive coat is softened by the sizing coat and until the adhesives have set sufficiently to keep the grains fixed during subsequent operations and handling. While facing downwardly, the sheet may be treated with a heated atmosphere containing in vapour form a solvent for the adhesive used, e.g. water in the case of glue, alcohol with phenol-aldehyde resin, naphtha or toluene with oil-modified alkyd resin. The sheet may be vibrated before and while it is caused to face downwardly in order to maintain or improve the orientation of the grains which may have been deposited by electrostatic coating methods, such as are described in Specifications 378,014 and 396,385. A web 10 of paper, cloth, or vulcanized fibre to which abrasive grains have been secured by means of a layer of hide glue passes from a drying room (not shown) around idler rolls 13, between rolls 14 where a sizing coat of glue is applied over the grains by the lower roll dipping in a bath 15, and around rolls 16, 17 to a chamber 18 in which the downwardly facing grain surface is subjected to the action of steam admitted through a pipe 21 and perforated plate 23. The web travels horizontally or at a small angle less than 30 degrees to the horizontal with the grain facing downwardly until the adhesive is set sufficiently to permit handling and then passes to drying rooms. The web may be vibrated by a rotating hexagonal bar 26 or other means, e.g. electromagnetic means, after leaving the steaming chamber and, if desired, also at an earlier stage.

Abstract: 287,900. Barrett Co., (Assignees o: Miller, S. P.). March 29, 1927, [Convention date]. Condensing, scrubbing, and washing processes ; hydraulic mains. - The hot gases evolved from coke ovens or retorts are cooled and freed from tarry impurities by spraying them with oil as they pass through the collector mains, the oil being in sufficient quantity to effect the cooling and scrubbing of the gases, and to dissolve the separated tar constituents and flush them from the main. The oils are preferably those obtained in the condensers of the carbonizing plant, and the process may be used to distil and purify dirty oils which are vaporized bv contact with the hot gases and afterwards recovered by condensation, the impurities such as tar and pitch being precipitated in the collector main and washed therefrom by the undistilled oil. The process also prevents pitch from hardening and accumulating In the collector mains. Means other than spraying may be used to bring the gases and oil into intimate contact, e.g. by mechanical agitation of the oil in the collector main by paddles, revolving discs, or plates, or by introducing compressed gases into the oil. The gases from a battery 5 of retorts rise through uptake pipes 6 into a collector main 7 where they are sprayed with oil introduced through nozzles 10 and 13. The products pass from a centre box 8 through a cross over main 9, where further oil with or without ammonia and water is introduced through nozzles 23 to condensers 27. The oils separated in the condensers pass through a decanter 29 to a tank 15 from which they are forced by a pump 14 to the nozzles 10, 13. Specifications 184,507 and 284,703 are referred to.

Filed: 1958-03-14
Abstract: 820,198. Electrical digital -data-storage apparatus. STANDARD TELEPHONES & CABLES Ltd. March 14, 1958 [March 16, 1957], No. 8291/58. Class 106 (1). (Also in Group XL (c)] An arrangement for producing a binary phase-modulation writing waveform in a magnetic recording head comprises a pair of blocking oscillators cross-coupled whereby when one oscillator is triggered by an external pulse, the trailing edge of its output pulse triggers the other oscillator. As shown, two identical oscillators S1, S2, each comprising a transistor T whose collector and base circuits are connected by a transformer U, are coupled through the transformer output windings W3 via resistors R1 and head winding K. The oscillators are selectively triggered by applying a negative pulse to input E1 or E2. If e.g. oscillator S1 is triggered by a pulse at E1, a pulse, Fig. 2, b, appears in the winding W3, the overswinging of the trailing edge, Fig. 2, a, being prevented by diode D. This pulse causes current flow in head winding K to produce an induced voltage of the form shown in Fig. 2, d. whose negative peak triggers oscillator S2. A further pulse, Fig. 2, c, is thus applied to the head, the complete current pulse being as shown in Fig. 2, e. Once an oscillator has been triggered, further triggering is prevented until capacitor C1 is discharged. If oscillator S2 is triggered first by a pulse at E2, the current pulse in the head will be as shown in Fig. 2, f.
