Title: Improvements in optical printing methods and apparatus
Inventor: SMITH FRANK GERALD
IPC: H04L13/18
Filed: 1966-11-18
Abstract: 1,122,605. Photographic type composing. CREED & CO. Ltd. 18 Nov., 1966, No. 51814/66. Heading B6W. [Also in Division G2] In an optical printing apparatus where a character to be printed is represented by a beam of light or other suitable radiation and in which the beam is progressively deflected by an optical system so that successive characters are printed as a line, flyback at the end of a line is achieved solely by switching from one to the other of two separate beam sources which are used alternately. Two plane mirrors A and B silvered on both sides are pivotally mounted mutually at right-angles at the focus of "parabolic" mirror C made up of plane mirrors M 1 , M 2 , M 3  &c. Character carrying light beam TR2 is reflected from mirror B on to a plane mirror M of the "parabolic" mirror and then to the printing site PS1 where the character is recorded by a photographic or xerographic process. For production of succeeding characters, mirror B is stepwise rotated anticlockwise. When the end of a line is reached mirror A is in such a position that a switch from character carrying beam TR2 to beam TR1 (associated with mirror A) will cause the next character to be reproduced at the beginning of the next line. Mirror A is used to compose the next line. In an alternative embodiment, Fig. 5, two separate "parabolic" mirrors D and E are arranged with pivoted plane mirror F, silvered on both sides, at their common focus. Plane mirrors J and K deflect light beams from parabolic mirrors D and E, respectively, into the printing plane PP. The first modulated light beam received is directed by route TR3 and via mirrors F, D and J to the printing plane. Mirror F rotates stepwise anticlockwise to print the first half of a line, the line being completed by switching to character carrying beam TR4 which is deflected into the printing plane via mirrors F, E and K, while mirror F steps clockwise back to its initial position. Flyback at the end of the line is then achieved by switching from TR4 back to TR3, while the printing surface is stepped to the next line.

In a filter press comprising alternate frames 2 and plates 3 in which filter cakes are removed by successive automatic displacement of plates and frames on guides 1, each plate has a coupling element 7 which engages the adjacent frame so that movement of the frame causes it to tilt until its angle of inclination is sufficient to release it from the coupling, whereby removal of cake from the frame and from the cloth of the adjacent plate is facilitated. Elements 7 comprise pivoted hooks which engage pins 8 or eyelets on the frames. In an alternative embodiment, the frames and plates move on guides at their upper ends and the coupling elements are located at the lower ends of the plates. The lower and side elements of frames 2 may be bevelled and the side elements may converge upwards. The filter cloth on plates 3 may be synthetic fibre and may be covered by an 'upper cloth' of silk-like fibres to facilitate release of cake. Closing, filling and washing operations and subsequent opening of the press may be automatically controlled by an electrohydraulic system.

Abstract: 1,205,628. Dyeing apparatus. P. ZIMMER. 20 Nov., 1967 [21 Nov., 1966; 30 Dec., 1966], No. 52612/67. Heading D1L. Carpet material is dyed by being moved in contact with at least one perforated screen cylinder in a direction transversely of the axis of the cylinder, the area of contact being a strip shaped zone parallel to the cylinder axis, the dyeliquor being applied to the material along said strip shaped zone through the perforations of the cylinder, and the peripheral speed of the screen cylinder being variable relative to the speed of the material to control the intensity of the dyeing. Material is unwound from a roll 2 onto a continuously moving endless belt 7. At a point intermediate the length of travel of the upper run of the belt the material passes beneath a rotating perforated cylinder 8. Dyeliquor is fed to the interior of the cylinder 9 through a pipe 9 and forms a supply 27 (Fig. 3) which is pushed outwardly .through the perforations onto the material by a roller 10 inside the cylinder. The roller is maintained in position above the strip zone of contact by a magnet 11 located immediately below the upper run of the 'belt 7. A common drive serves both the belt and the cylinder but an infinitely variable transmission gear is used for the cylinder so that for any given change in speed of the belt the ratio can be maintained between the belt and cylinder. This is because the cylinder must always rotate with a faster or a slower speed in the strip shaped drying zone than the belt to prevent damage to the material. Preferably the ratio is always 2:1 or 4:1 or vice-versa.

Abstract: 1373545 Gearing; friction clutches; clutch control REVENUE SYSTEMS Ltd 14 Nov 1972 [16 Nov 1971] 53126/71 Headings F2Q F2C and F2L  Oscillating motion of a pulley BA is produced from the continuous rotation of a driving shaft AW by the engagement of a clutch band BE secured to the pulley, with a driving drum AZ secured to the shaft AW, for a part of a revolution of the pulley BA, the pulley being returned to its original position by a cable BC acted on by spring means. The initial position of the pulley BA is defined by a stop pin BL fixed to it engaging a fixed rubber stop (Fig. 4, not shown). The engagement of the clutch is by rotation of a lever BG, Fig. 2, anticlockwise about a pivot BH, which rotation causes a cam follower BN to pass through a slot (Fig. 3, not shown), in a cylindrical cam band BU and move around the surface of the cam band BU as the pulley BA rotates, until a further slot is reached which the follower BN passes out through, urged by a spring BW, to disengage the clutch and allow the reverse rotation of the pulley by the cable BC. The actuation of the clutch is by a pin which acts on the follower BN to push it radially inwards when an electomagnet is operated. The device may be used in the production of reciprocating motion of a carriage.
