Title: Method of transforming vesicular images
IPC: G03C5/60
Filed: 1971-04-19
Abstract: 1334756 Photographic processes using vesicular images CIBA - GEIGY A G 19 April 1971 [13 March 1970] 23997/71 Heading G2C A method of transferring vesicular images in thermoplastic binders to non-vesicular images, preferably visible in visible or U.V. light, which comprises treating the image with an organic solvent which penetrates the vesicles and simultaneously or subsequently treating with an image producing compound which is laid down in the image areas, the gas in the vesicles either being released by the organic solvent or in a subsequent step. Specified compounds are metallic salts, organo-metallic compounds dyes, ultraviolet absorbers or optical brighteners. Preferably, either (i) the solvent containing the compound causes the bubbles to swell but does not release the gas thus depositing the compound in the bubbles and, if necessary, removing any remaining gas by solvent or heat or (ii) a solvent which bursts the bubbles is used and the compound is applied simultaneously or subsequently. In the examples, a vesicular image is treated with a solvent such as z-ethoxyethanol, the solvent either containing a dye, an optical brightener or ultraviolet absorber or such a solution containing ore of these components being applied after the initial treatment with solvents. Multi-coloured pictures may be produced by making vesicular images of 3 or 4 colour separation negatives and treating the images above using appropriately colour dyes and registering the dyed images which may be used as colour proofs. Alternatively, visible images may be produced by immersing the vesicular image in 2-methoxyethanol solvent which bursts the bubbles, dipped in ethyl alcohol, immersed in a wetting agent and then treated with an aqueous solution of a dye or silver nitrate and ferric ammonium nitrate (which requires subsequent exposure to produce a silver image) or aqueous solution of lead nitrate and sodium sulphide applied successively. The dye solution may be added to the wetting agent solution. Two-coloured images may be produced by applying a solution of organic solvent aid dye to our developed but unfixed vesicular image, imagewise exposing and developing a different area to produce a second vesicular image, treating with an organic solvent followed by an aqueous solution of wetting agent and then an aqueous solution of a different coloured dye. The dye or other images produced are rendered more permanent by (i) closing the pores using heat on solvent vapour or (ii) applying a protective varnish.

Abstract: 190,214. MacCallum, A. H. S. Sept. 10,1921. Current detectors; locating faults. - An indicator is placed in series with a sparking plug, and an inductance is placed in parallel with or is inductively connected to the indicator. The inductance 9 may be wound on a hollow cylinder 3 within which a spark gap is formed between members 10, 11 connected to the inductance and to upper and lower plates by screws 8. A mica or like cover closes the sparking chamber. In one modification the cylindrical block need not be hollow, the upper and lower plates being bent so as to lie parallel to each other at the side of the block; the spark may pass directly from one to the other, or indirectly by way of a removable indicator. When the indicator is ,inductively connected in the circuit, two coils are wound on a bobbin, the terminals of one coil being connected to the plug and generator and those of the other to the indicator. In a further modification, the spark gaps may be mounted at a distance from the inductances, and may be brought into operation by the movement of a rotatable or slidable member carrying one of each pair of contacts. Instead of spark gaps, vacuum tubes containing, for example, neon, hydrogen or nitrogen at a low pressure may be used. The glass of the tube may be fluorescent. A condenser may be connected in the coil and indicator circuit.

Abstract: 1,057,074. Sorting machines. STANDARD TELEPHONES & CABLES Ltd. June 11, 1964 [June 18, 1963], No. 24244/64. Heading B8A. A machine for sorting articles from trays to a number of bins at a number of sorting positions includes means for moving the bins in one direction through the machine below the trays, and means for causing the trays to move at a constantly varying velocity in a reciprocating manner above the bins. In a mail-sorting machine such a motion is applied to a conveyer 37 which moves trays 34. These trays feed mail into bins 35 which are movable but which are stationary when mail passes therein from the trays 34. Mail is ejected by devices 36 into the bins via shoots 36a. Fig. 10 (not shown), indicates that the tray conveyer 37 moves forward 10 bin lengths and then backward 6 bin lengths. During the movement of the trays in the reverse direction the bins are moved in this same direction 5 bin lengths. At each of the bin position 200-245, sensors detect the destination of the bin underneath and mail having the same destination is ejected. An edgewise conveyer system carrying mail may be stopped, moved slowly or moved in reverse in front of an operator to enable him to read and record the address. Drive for an endless conveyer belt 1.-In Figs. 1-3 (not shown), means are provided which produce an intermittent movement of the belt 1. This belt is driven by a belt 7 which engages a pulley 6 also engaged by the conveying belt 1. Idler pulleys 11, 12 are mounted in bearings 19 which are slidable in a slot 20 of a base plate 22. A rod 14 connects the pulley 12 to a pulley 13 driven by a motor 24 and is adjustably located in a slot 15. The reciprocating action of the pulleys 11, 12 imparts a sinusoidal movement to the belt 7 which either adds or subtracts velocity to the belt 1. By varying the position of the rod 14 in the slot 15 the amplitude of the sinusoidal movement can be varied. The belts may thus be momentarily stopped or reversed. The portion of the belt 7 between the pulleys 6, 9 may be used as a conveyer and the belt 1, together with its pulleys, dispensed with. All the pulleys may be sprocketed and the belts provided with co-operating slots.

Filed: 1957-08-01
Abstract: 849,457. Optical apparatus. RANK PRECISION INDUSTRIES (B.A.F.) Ltd. Aug. 1, 1957, No. 24382/57. Class 97(1) [Also in Group XXXV] In order to move crossed mirrors rapidly between two positions, an optical apparatus is provided with an electro-mechanical device having a reciprocable drive member adapted to be accelerated between two selectable limit positions by the action thereon of electro-magnetic actuating elements, two at least of which are successively operative in accelerating the member towards either limit position. As shown, mirrors 1 and 2 are mounted one above the other and in orthagonal planes on a shaft 3 which is slidable in bearings of which the bearing 23 is spring connected at 16 to a metal collar 22 on the shaft 3. Surrounding shaft 3 are pairs 9, 12 and 10, 11 of electro-magnets for co-operating with the collar 22, that electro-magnetic pair which is operative depending upon the position of a change-over switch 8, actuated by a pin 17 projecting from shaft 3. This switch is in a circuit which contains supply source 28, switches 4, 5 and 27, relays 6, 7 and solenoids 13, 26, which co-operate with contacts 25, 19 and latches 14, 18 to define with a notch 24 in shaft 3 two limit positions of the shaft. In the lower position mirror 1 reflects light from camera A while in the other position mirror 2 reflects in the same direction light from camera B. When inoperative, notch 24 is midway between latches 18, 14 with the spring 16 at zero compression and both contacts 19 and 25 are closed. To obtain the upper limit position of shaft 3 in which mirror 2 is in the light path, switch 4 is closed and with switch 8 in the position shown, coil 9 pulls shaft 3 upwards until pin 17 actuates switch 8 so as to energise coil 10. By this alternate action the oscillation of shaft 3 builds up with the assistance of the spring 16 until the collar 22 overshoots coil 9 at a time when this coil is de-energised. Coil 11, which is energised simultaneously with coil 10, then pulls shaft 3 to its upper limit position whereupon latch 18 falls into notch 24. To cause shaft 3 to occupy its lower limit position, switch 5 is closed and the cycle of operation is repeated.

Abstract: 938,442. Automatic control of container filling machines. INDUSTRIAL NUCLEONICS CORPORATION. July 6, 1961, No. 24569/61. Class 38 (4). In an automatic control system for a dispensing machine, through which a plurality of containers pass in succession, an adjusting device for varying the volume of material placed in each container is controlled by a detecting device producing a signal indicative of the average height to which the material is placed in the containers so as to maintain the fill height at a predetermined level. As shown, a row of containers 40, Fig. 2, to be filled, pass into an automatic dispensing machine 20 and the filled containers 41 are scanned by a staggered arrangement of a cesium source 10 and G.M. tubes 11 positioned so that the cans present a continuous barrier to the radiation. The output of the G.M. tubes is fed to a measuring bridge circuit 8 energizing a contactmeter 150 arranged to operate a low-fill controller 70 or a high-fill controller 72. The controllers are connected to a reversible motor 58 varying the volume dispersed so as to maintain the height of material in the container constant. In the measuring bridge circuit, Fig. 7, the output of parallel-connected G.M. tubes 11a-11c is fed through an integrating circuit 104 to a bridge circuit comprising triode valves 1, 2 and having a contact-meter 150 as a bridge-balance indicator, a coil 150a being in series with a rheostat 119, controlling sensitivity, across the output of the bridge. The bridge is set at the desired fill-height by a rheostat 110. Movement of the contact-meter pointer 150c outside of the set limits closes a switch 150d, 150c to energize a hold-on coil 150f, 150g through contacts 120a of a delay timer 120 to bias a grid 128, 142 and render a thyratron 3, 4 conductive. A relay 140, 160 is energized by the thyratron to open contacts 140a, 160a in the supply to the other thryatron 4, 3 and close contacts 140b, 160b to energize the appropriate field winding of a motor 58 so as to tend to correct the variation in the fill-height. The delay-timer 120 runs continuously and is arranged so that contacts 120a disconnect the hold-on coils and the grid bias to the thyratrons for a sufficient period in each cycle for the results of a previous corrective action to be measured by the bridge. Specification 938,441 is referred to.
