[Class 98 (ii)] A photographic image is formed in an exposed silver salt emulsion having incorporated therein a developing agent by subjection to moist vapours of such chemical composition to cause the pH of the emulsion to rise until the developing agent develops the latent image. The emulsion may be a silver bromide, chloride, or bromiodide emulsion, and may be a modified Lippmann type emulsion. The developing agent added thereto may be hydroquinone, metol, amidol, or p-phenylenediamine, and a stabilizing agent, e.g. sodium sulphite, may also be added. The exposed material is treated with alkaline vapours such as moist ammonia vapours or vapours produced by heating an aqueous solution of a volatile amine (e.g. vapours produced by heating aqueous ammonium hydroxide or aqueous methylamine or ethylamine) or, where the emulsion contains sodium sulphite, by treatment with acetone vapour. After development, the material may be treated with acid vapours to stop development. In an example, to a fine grain gelatino silver bromiodide emulsion is added hydroquinone and sodium sulphite, and the emulsion is coated on a glass, film, or paper support. The exposed material is developed by treatment with vapours obtained by heating aqueous ammonium hydroxide or aqueous methylamine or ethylamine, is subjected to a stream of compressed air, and is then treated with vapours from aqueous hydrochloric acid.

In a splitting-machine in which a workpiece 1 is fed, between an adjustable guide-roll 2 and a spring - biased pressure - roll 3, against the cutting-edge of a band knife 5, the thickness of the processed workpiece is measured by means of an apparatus including two feeler members, one of which is the roll 2 and the other of which is a measuring roll 6. The roll 2 is held in a holder 14 at the end of a spindle 17 which is movable axially by means of a worm-wheel 18 engaged by a worm 23 driven from a reversible electric motor 13. The roll 6 is carried by a spring-biased pivotally-mounted crank-lever 83. The pre-adjustment position of the roll 2 is indicated by a pointer 93 carried by the holder 14 and movable over a scale 92. The holder 14 has attached thereto a bracket arm 89 on which is slidably mounted a slide 86 carrying a pointer 49 and adjustable with respect to a scale 48 by means of a fine adjustment drive 85. The slide 86 is provided with a stop 50 movable between stops 51, 52 on the bracket arm 89. The slide carries a gauge 84 having a feeler pin 87 which bears against one end 88 of the lever 83. The gauge pointer 61 acts as the moving contact of a switch between two fixed contacts 11, 12 corresponding respectively to the lower and upper thickness limits of the processed workpiece. The switch controls the motor 13, to automatically maintain a desired thickness of the processed workpiece while the workpiece is passing through the machine, by means of the circuit shown in Fig. 3 which includes a switch 7, which is closed when a workpiece is fed between the rolls 2, 3, a time delay switch 8, relays 56, 58, 79 and a transformer 78. The circuit also includes a manually-operable switch 95 which serves for controlling the motor 13 during the pre-adjustment of the roll 2. The drive to the spindle 17 may be coupled to the roll 2 by means of a circuit controlled through the contacts of the gauge 84 so that the speed of advance and retraction of the roll 2 is always in the same ratio to the speed of the roll 2. The roll 3 is preferably segmental.

Title: A method of, and means for effecting registration of packaging webs in packaging machines
IPC: B65B9/213
Filed: 1965-12-10
Abstract: 1,097,086. Packaging-machines. TEPAR A.G. Dec. 10, 1965 [Jan. 21, 1965], No. 52579/65. Heading B8C. A packaging machine in which articles or increments of material are fed into a tube of packaging film &c. which is sealed transversely at intervals to form packages, includes means which flatten end flaps formed by package shaping and are used to vary the distance the tube is fed through the package-forming area to produce registration of the package or printing &c. relative to the transverse sealing, severing or other operations. The machine forms rectangular sided packages by associating mould halves 2, 3 and end flaps forming members 4 with the sealing- jaws 6, 7. The members 4 are pivoted assemblies at 5 and their inward swinging, flap pressing movement normally draws down the tube to an extent additional to that accomplished by the (as shown) vertical reciprocating movement of the closed jaws and mould halves. This additional movement is varied for registration purposes by reducing the inward swing. Pivoting of the members 4 is produced by lever and draw rod means 11, 14, Fig. 4, the rod 14 being moved horizontally by a cam track 16 as the jaws and mould move vertically. The throw of the draw rod and thus the movement of the members 4 is altered by shifting the cam track horizontally by pneumatic or other means 24 in response to signals emanating from a photo-electric device (not shown) scanning marks on the packaging web. The jaw and mould means may be duplicated for continuous tube movement. Coarse and fine movement of the track 16 is provided for.

Abstract: 911,573. Sawing. T.I. (GROUP SERVICES) Ltd. May 12, 1961 [Feb. 17, 1960], No. 5579/60. Class 145. Tubes or bars 11 to be cut into lengths by a saw are fed in steps against a stop by a feed member on an endless chain and if the end piece of tube or bar is shorter than the required length the feed member reaches the end of its stroke before the leading edge of the tube or bar reaches the stop and operates a limit switch or valve to cause the short length to fall to a different container from that for the cut lengths. The length to be cut is supported in a V-shaped trough 16 between the saw and the stop and when the saw has cut through the tube or bar the trough is pivoted down by a pneumatic cylinder 18 and the cut length is delivered over a flap 19 into a container. For the short end piece, the operation of the limit switch or valve causes a pneumatic cylinder 20 to pivot the flap 19 out of the way and allows the end piece to fall to a different container.
