Abstract: 845,972. Louvre assembly. APPLETON PTY. Ltd., N.V. April 12, 1958 [April 23, 1957], No. 12777/58. Class 137 An adjustable louvre assembly comprises a pair of jambs to which are pivoted louvre clips which carry louvre blades, the clips being connected for simultaneous adjustment by pairs of bars disposed between and pivoted to each set of clips and the jamb on which they are mounted a rigid torque transmitting bar mounted at its ends in clips of the respective jambs to transmit a turning moment applied to one set of bars, by e.g. an operating handle, to the other set of bars. As shown, the louvre clips 28, pivoted at 25 to the channel-shaped jambs 23, are connected for simultaneous adjustment by pairs of bars 27 pivoted to the flange 26 of pivot 25, movement of the bars being effected by the handle 29. One louvre blade 31 has two rectangular recesses 37 stamped in it which carry fixing plates 40 of the torsion bar 39 which transmits movement of the bars 27 from one side of the assembly to the other thereby avoiding distortion of the louvre blades. In a modification, the torsion bar (Fig. 8) is fitted to a louvre blade 30 between the arcuate strips 36 and is a further modification (Fig. 11) the arcuate strips 36 are formed at the end of a louvre blade and two prongs 45 of a fitment carrying the torsion bar are received in the gaps formed by the strips.

Title: Copying machine
IPC: G03B27/14
Filed: 1972-03-20
Abstract: 1388897 Contact printing HOECHST AG 20 March 1972 [27 Aug 1971] 12804/72 Heading G2A A copying machine including a feeding and cutting device for reproduction material in web form also includes a device for sensing the length of an original to control said devices in order to supply from a travelling web of said material a portion of a suitable length in relation to the length of the original, said sensing device including at least one control element for sensing the leading edge of the original and one for sensing the trailing edge, said elements co-operating with an electronic computer whose output is dependent on the rate of travel of the original. In the described embodiment there are two rolls 1, 2 of reproduction paper of differ-  ent widths and two sets of control elements 21a, 21b, (21a' 21b') one or the other set controlling its related web according to whether the original 13  is fed to the machine on one side of the table 18 or the other. More than two webs may be incorporated with corresponding control sets. The control elements are adjustably mounted, Fig.3, on a lever 26 whose end passes over a scale 28, so that their positions may be varied to allow for originals having margins and hanging strips which are not required to be copied. Each web 3 or 4 passes through draw off rollers 5,6, reserve loops 16, 17, feed rollers 7, 8, cutting device 9, moveable guide means 10 and rollers 11 to roller 12 where it is associated with the original 13 and passed to a copying station. The sensing of the leading edge of the original, being fed by rollers 19 at a predetermined speed gives an impulse to the time computer which calculates a time delay dependent on the selected speed and also the characteristics of the feeding device. After this delay and considering the web 3 to be selected the feed roller 7 causes the web of material 3 to be fed to rollers 11 at the same speed of travel as the original, taking up the loop 16 actuating a switch 49 causing the draw off rollers 5 to operate to withdraw material at a speed greater than the speed of the original and restore the loop, this process being repeated several times depending on the length of the original. When the trailing edge is sensed an impulse to the computer causes it to calculate another delay after which the feed rollers are braked to standstill. After a further time delay the cutter is actuated. Voltage adjustment may be made by knobs 57, 58 for copying originals with hanging strips and to set the machine up for manual operation or to cut test strips from the webs to check exposure times.

[Class 146 (i).] In a card-index cabinet employing a central guide 2 over the front edge 3 of which the cards 7 drop to expose parts of successive cards as the card drawer 6 is advanced relatively to the guide 2, the drawer 6 has, in addition to its horizontal movement, an independent vertical movement so that it can be raised to render the guide 2 ineffective until the drawer is lowered, when the edge 3 is adjacent to the cards it is desired to inspect. The drawer is detachably supported on a carriage 4 by crossed links 8 connected by a spring tending to raise the drawer to its upper position, the carriage being slidably mounted in a housing 1 by means of rearwardly extending runners 5 as usual. A pivoted catch 16<a> is provided on the front of the drawer to engage the bottom of the carriage 4, to hold the drawer in its lower position when it is desired to inspect the cards by moving the drawer, either by a direct pull on the drawer front, or by operating, by means of a knob 23, a gear arrangement 22, 26 co-operating with a rack 27 on the casing 1. In order to prevent displacement of the cards as they move over the surface of the guide 2 a ribbon or belt 17 fastened to the carriage 4 at the opposite ends passes along the surface of the guide 2 and over rollers 19, 20, so that it moves with the cards. Slight longitudinal movement of the guide 2 in the casing 1 is allowed under the action of a spring 29 so that the exposing of the cards can take place outside the casing 1.
