IPC: G05D16/12
Abstract: 1,053,057. Valves. INSTITUT FœR SCHIENENFAHRZEUGE. April 13, 1964, No. 15186/64. Heading F2V. A pressure regulating device using a liquid seal comprises a first vessel 1 adapted to contain a liquid seal adapted for connection to a pressure system in such manner that the pressure in the system is conveyed to the interior of the first vessel, and a second vessel 2 which is in cornmunication with the interior of the first vessel through a flow path including the liquid. The first vessel includes tubes 7 connecting the interior of the vessel to a pressure system comprised by the air above the level of water in a tank 10 and a pipe 5 with a pot-shaped end 6 which is filled with a liquid such as mercury is in communication with vessel 1. The vessel is fixed through flanges 8 to the wall of the tank 10. The second vessel has an outlet connection 22 to atmosphere, a pipe 14 leading to the potshaped end 6 in which mercury forms a liquid seal, and a body 19 supported on a series of spiral-shaped, radially-disposed ribs 20 for preventing evaporation of the liquid forming the liquid seal. Any pressure increase of the system will force mercury up the tube 14 and air will bubble through the mercury to atmosphere. When the air pressure in tank 10 falls below the set minimum value, atmospheric air will force the mercury out of tube 14 and bubble through the mercury into tank 10.

Abstract: 1,054,125. Photopolymerizable materials. GEVAERT PHOTO-PRODUCTEN N. V. April 10, 1964 [April 22, 1963], No.14901/64. Heading G2C. [Also in Division C3] Photopolymerizable compositions comprising ethylenically unsaturated monomer compositions and containing azohydroperoxides as photopolymerization initiators (see Division G3) are used in the production of photographic images. The photopolymerizable composition deposited on a support is exposed to actinic light through a process transparency when the exposed material is rendered insoluble after which the non-exposed areas are washed off with a monomer solvent. Specified supports are paper, cellulose triacetate films, polyethylene terephthalate films and aluminium foils - where the support is light reflecting, there may be superimposed a layer absorptive of actinic light. The compositions may be used as photoresists for manufacture of planographic printing plates, for "silk screen" printing and other classes of printing.

Abstract: 1,143,618. Endless conveyers. GRAHAMENOCK MFG. CO. Ltd. 22 Sept., 1967 [10 Aug., 1966], No. 35745/66. Heading B8A. [Also in Division A4] An article treatment apparatus comprises means for conveying a succession of articles in line formation through a treatment zone and control means for successionally holding an article of the line stationary whilst permitting the preceding article to travel through the treatment zone to provide a controlled spacing between articles progressing through the zone, including co-ordinated stop members comprising a downstream member for holding an article stationary in the treatment zone, and an upstream member for holding the succeeding article stationary when the downstream member releases the first article. In a machine for spray washing bottle crates in which the crates are carried through a washing zone 3 by a conveyer comprising spaced endless bands 1 and 2, stops 6 and 7 are formed at opposite ends of a cranked frame 5 which is pivotable by a ram 8 so that either of the stops 6, 7 is in the path of the crates. The stop 7 is effective to hold the leading crate 10 stationary in the washing zone until the ram 8, controlled by a timer 9, tilts the frame 5 to raise the stop 7 to release the crate 10, and to lower the stop 6 to prevent the succeeding crate 11 from moving fully into the washing zone. After a short interval to allow the crate 10 to become spaced from the crate 11,  so that the rear side of the crate 10 may be washed by the sprays, the ram 8 operates to lift the stop 6 and lower the stop 7 to permit the crate 11 to enter and to be halted in the washing]zone.

Abstract: 1,234,239. Digital weighing systems. ZAKLADY MECHANIKI PRECYZYJNEJ. 23 Dec., 1968 [23 Dec., 1967; 26 Sept., 1968], No. 61201/68. Heading G4H. A weight measuring system comprises a balance beam 1 pivoted on knife edge 1B and carrying a pan on the other edge 1A holding an unknown sample and a number of removable calibrated weights, a coded scale 2 on the other end of the beam, reading means 8 for the scale indicating the deflection of the beam from a datum position which is a measure of the weight of the sample, a cam-and-link mechanism to remove or add selected calibrated weights to restore the balance of the beam under the control of the reading means and means providing a visual read-out of the weight of the sample. The weight of the arm to the right of the edge 1B is exactly balanced by the weight of the arm to the left of the edge plus the weight of all the removable calibrated weights on the pan. The calibrated weights could be the other side of the pivot, the weights then being added instead of removed. The weight of the sample causes displacement of the beam which moves an image of the scale 2, projected by lamp 3, lenses 4, 5 and mirrors 6, 7 over the reading unit 8. The scale, Fig. 2, has ten zones 9 each capable of giving a coded representation of a units digit and a single zone 10 giving the tens digit. The senser unit 8, Fig. 3, has four photocells A-D in slit 13 sensing the four tracks of zone 10 and leading and lagging groups of four photo-cells E-H and I-L in slits 14, 15 for sensing the four tracks of the appropriate zone 9. One or the other of the groups is selected in accordance with the value of the 1 digit A of the tens group. This avoids transition errors when passing from 9 to 10. The two decades are each decoded to give outputs on one of ten leads and display a corresponding decimal number. This number is also recoded in a fourbit binary code for each decade, the bits having weights 1, 1, 2 and 5. These are used to control cam and link apparatus (Fig. 6, not shown) for removing calibrated weights from hangers on the pan so that the weight removed corresponds to the value indicated by the scale 2. The unknown weight should therefore be compensated to within one unit of weight and the beam returns to its balanced position. The pan is then transferred to another beam for a fine indication giving digits valued 0À1 and 0À01. If desired, a still finer indication may be derived from a third beam.
