Abstract: 1,267,187. Cameras. AGFA GEVAERT A. G. March 6, 1970. [March 7, 1969], No. 10856/70. Addition to 1, 135, 150. Heading G2A. A spring-loaded locking slider 106 which prevents double exposure provides the motive power which actuates the two shutter blades 109, 112 which move one after the other, separated by a delay device, to effect the exposure. Figs. 1 and 2 show the mechanism in a tensioned position, ready for an exposure to be made. Shutter blade 109, in its rest position, covers the exposure aperture 108, and is urged clockwise about a pivot 111 by a spring 110. The other shutter blade 112, which is urged clockwise about a pivot 113 by a spring 115, is held, against the action of the spring, in the position shown, in which it does not cover the aperture 108, by a release lever 114. Lever 114 is pivoted to slider 106 at 116, and held in the position of Fig. 2, against a spring 117, by a lug 106c engaging a pin 118 on the lever. The slider 106 is tensioned by a spring 107, and is mounted on the camera body by a pin-and-slot arrangement 138, 106a, so that both sliding and . rotational movement is possible. The slider is retained in the position of Fig. 2, against the spring 107, by the engagement of a cam 105a on the winding knob 105 against an angled extension 106/ at the front end of slider 106. When the shutter release bar 102 is pressed downwards, a lug 102b on the bar enters a recess 126 in the part of the camera wall on which slider 106 is mounted. At the same time a pair of switch contacts 122 is closed, which energizes a delaying device Z including an electromagnet 120 which, via an armature 119, retains lever 114 in the position shown. An oblique surface 102c of bar 102 pivots slider 106 in the direction of arrow 124, which brings it clear of cam 105a, so that it is now free to slide to the left under spring 107. An extension 106b of the slider strikes a lug 109a of shutter blade 109 and pivots it anti-clockwise, so that aperture 108 is uncovered. As the slider moves, lug 106c comes out of engagement with lever 114, but this is still held by the magnet 120. Also, a pin 106d on the slider releases switch contacts 121, which causes the device Z to receive a starting pulse. Movement of the slider is temporarily arrested by the lug 102h. After a period of time determined by the device Z the magnet 120 is de-energized, so that lever 114 is released to pivot under spring 117, and thus the second shutter blade 112 is released in turn. This accordingly pivots to cover the aperture 108 and so terminate the exposure. If the shutter bar 102 is now released, it moved upwards again under a spring 103, so that slider 106 can move further still to the left, and pivots back into the position of Fig. 2. An extension 106e of the slider is now underneath lug 102b, so that the release bar 102 cannot be pressed down again. Shutter blade 109 is also released so that it covers aperture 108 once more. Fig. 3 (not shown) has a modified arrangement of the shutter blades, so that these move in the same direction to effect the exposure, like a slit shutter, instead of in opposite directions.

Abstract: 1296244 Desalinating sugar solutions by electro-dialysis TAITO K K and ASAHI KASEI KOGYO K K 7 July 1970 [7 July 1969 14 Nov 1969] 32991/70 Headings C6B and C7B A sugar solution is desalinated by electrodialysis between a non-selective ion-permeable, or NS, membrane having a cation or anion exchange capacity of less than 0À3 meg. /gr. of dry membrane and a cation permselective, or K, membrane of resin material. Suitable materials for the NS membrane are cellulose, parchmentized paper, cellulose acetate, polyvinylalcohol or other ion-permeable polymers. As shown in Fig. 2 a number of K membranes 3 alternate with NS membranes 7 between the cathode 1 and anode 2, and the sugar solution is passed through dilution compartments 5 whilst a stream of e.g. an aqueous solution of sodium chloride, sodium sulphate or sea water, is passed through concentration compartments 6 to receive the ionizable components to be removed from the sugar solution. Fig.3 shows another embodiment in which anion exchange membranes 4 are interposed between NS and K membranes to provide additional compartments 8 for a rinse stream which may be an aqueous solution of sodium chloride, sodium sulphate or sea water. Ionizable components pass from the dilution stream into both the concentration stream and the rinse stream, and from the latter into the concentration stream, and any sugar leakage into the rinse stream may be recovered by transferring the rinse stream to the dilution stream. Sugar recovery may be improved by employing, before or after the electro-dialysis process, a conventional sugar refining process such as defecation, carbonation, phosphatation, sulphitation or adsorption, e.g. with bone charcoal etc. or ionexchange or adsorbent resins.

In the embodiment shown, sextuple length filter rods are supplied by a hopper to grooves 3 of a feed drum 2 that transfers them to grooves 6 of a cutting drum 1. The cutting drum 1 and the feed drum 2 are driven by suitable gears to provide a rotational speed ratio of 6:5, and these drums are provided with 15 and 3 grooves respectively. During each of the first five revolutions of the cutting drum 1, a length is cut off the rod as it passes a rotary cutter 8 and the cut off section is discharged from the drum 1 by a finger 10. Following each cut and the subsequent discharge of the cut off section, the remainder of the filter rod is moved axially along its groove 6 by an air jet to abut against an end plate 7 of the drum 1 to be ready for cutting off the next section or, in the case of the remainder after the fifth cut, to be ready for discharge by the finger 10 after passing (but not this time being cut by) the cutter 8. The end plate 7, which retains the rod in an axial direction, can be replaced by different end plates of varying thicknesses or formations to enable the axial length of each section to be cut from the rod to be varied. The internal width of the hopper is also adjustable, by means of spacer plates (31) to accommodate different lengths of multiple length filter rod. By repositioning the feed hopper and drum 2, adding a second feed hopper and drum system, and providing a cutting drum with 30 grooves, alternate cut lengths of two types of rod may be delivered by the cutting drum to enable dual filters to be assembled. The lengths of the alternate plugs may be varied by use of an end plate for the cutting drum provided with projections to fit into alternate grooves or by the use of an intermediate plate shaped to cover alternate grooves.
