Abstract: 449,824. Electrostatic meters. EGYESULT IZZOLAMPA ES VILLA-MOSSAGI RESZVENYTARSASAG, Ujpest, near Budapest. March 22, 1935, No. 9006. Convention date, March 22, 1934. [Class 37] [See also Groups XL and XXXVIII] Electric oscillations are recorded by controlling a beam of ions to produce electric charges on an insulating surface which is then dusted with powder to render the record visible. An arc light 1, Fig. 1, acts as a source of ions and is adjacent to a metal plate 5 having a rubber facing 6. A varying potential 7 is applied between the plate 5 and arc 1 and the plate 5 is moved. The ions from the arc are attracted towards the plate 5 in accordance with the varying potential 7 and produce electrostatic charges on the rubber 6 which may be made visible by dusting with sulphur or minium. A diaphragm may be placed between the surface 6 and the arc 1, Fig. 3 (not shown), and an initial biassing potential may be applied to the diaphragm. The record surface 6 may be in the form of a drum having a cylindrical inner electrode 5. The source of ions may be a flame, a corona or gas discharge, or an incandescent metal coated with an electron-emitting substance. The ionic beam may be controlled magnetically. Specification 305,168, [Class 37], is referred to.

Filed: 1938-03-25
Abstract: 507,692. Cleaning and oiling metal. UNITED ENGINEERING & FOUNDRY CO. March 25, 1938, No. 9198. Convention date, April 1, 1937. [Class 82 (ii)] Metal articles are oiled after pickling by rinsing in cold water while still wet and then, without permitting them to dry, oiling them. The rusting which may occur during the normal method of drying the articles after a hot-water rinse and before oiling is thus avoided. In one method, the articles immediately after a cold-water rinse are sprayed with, or immersed in a bath of, water-miscible oil. Alternatively, a bath of difficultly miscible oil may be employed, the oil being agitated so as to flush the adherent water from the articles. In the preferred method a mixture or emulsion of oil and water is employed, either as a'spray or a bath, preferably at a temperature between 150 and 200‹ F. The protective film is improved by adding a small quantity of difficultly-miscible oil to the emulsion and agitating it. In an example, the bath comprised 2 per cent of easily miscible oil and 1 per cent of difficultly-miscible oil in water.

Filed: 1938-03-25
Abstract: 496,024. Amusement apparatus. HEMMINGSEN, C. C. March 25, 1938, No. 9226. Convention date, April 22, 1937. [Class 132 (i)] An amusement apparatus of the kind comprising a curved track 2 along and over which a number of cars 3 are adapted to be moved, the cross section of which track is concave, so that in the curved portions of the track the cars are caused to move, due to the action of centrifugal force, outwards and upwards in the lateral direction along the concave crosssection of the track, is characterized in that the track has a circular cross-section and that the cars are connected in such a way with a propulsive device situated outside the cars and moving continuously and being positively controlled along the said track together with the cars that the latter when affected by centrifugal force in the curved portions of the track may swing laterally outwards in an arc of a circle from the central line of the track. The propulsive devices are situated below the track and run on a guide rail 4, and carry transverse axles 5 carrying wheels 6 running on rails 7 parallel to the central rail 4, to absorb capsizing forces. Each propulsive device carries a standard 8 projecting through a slit 9 in the floor directly above the rail 4.

Title: Improvements in and relating to platen printing presses
IPC: B41F1/28
Filed: 1932-03-31
Abstract: 388,234. Printing-machines. SCHNELLPRESSENFABRIK AKT.-GES. HEIDELBERG, Heidelberg, Germany. March 31, 1932, No. 9316. Convention date, March 2. [Classes 100 (i) and 100 (ii).] Platen machines ; delivery apparatus ; drying- apparatus.-In a method of automatically delivering the sheets in platen-printing presses by means of grippers rotating in the plane of the platen, each sheet is smoothed on its way from the platen to the pile. The invention is described as an improvement in the delivery of the platen press described in Specification 23358/13, [Class 100 (i), Feeding and delivering webs &c.]. The platen press, shown in plan in the Figure, comprises a frame 1 on which type 1<1> is mounted, and a platen 2 rotatable about an axle 3. Two grippers 4, 4<1>, arranged on the platen 2 and rotatable about an axle 5, are driven intermittently in such a manner that a gripper grips a sheet a, which has previously been lifted by suckers 6 from the feeding pile 7, and during the closing movement of the platen 2 guides the sheet on to the platen surface for printing. After the printing, during the opening movement of the platen, the gripper delivers the sheet to the delivery pile 8. Arranged in the vertical wall of the delivery side in the frame 9 of the type 1<1> are a number of nozzles 10 from which air is blown between the sheet and the type as soon as the gripper moves the sheet at the opening movement of the platen, so that the sheet is smoothed and peeled from the type 1<1>. A fixed support 11 of the press frame 1 carries a rotatably mounted compressed-air distributer 12 provided with a U-shaped tube 13 having downwardly directed nozzles, and a rotatable tube 14 provided with an oblique tube 15 having nozzles which direct air in a direction opposite to the direction of movement of the sheet coming from the platen. Below the tube 15 there is arranged on the support of the pile 8 a polished guiding-sheet 16 over which the sheets pass and on which they are pressed by the air streams from the tube 15 to smooth out any irregularities. Each sheet is thus guided smoothly up to the pile 8 where it is pressed against the other sheets of the pile by the downwardly directed air streams from the tube 13. The air streams which effect smoothing also accelerate the drying of the print. The compressed air is controlled so that it acts on the sheet on the commencement of withdrawal of the latter. Instead of using the tube 15 the sheets may be passed between guiding walls, brush surfaces, or the like, and where guiding walls are used the upper one may be provided with compressed-air nozzles which direct air on the sheets to keep them on the lower surface to avoid smudging the print.

Title: Improvements in or relating to pneumatic conveying systems
IPC: B65G53/52
Filed: 1947-04-08
Abstract: 622,862. Pneumatic conveyers. BOBY, Ltd., R., and ROCKLEY, H. J. April 8, 1947, No. 9338. [Class 78 (i)] A pneumatic conveying system (Figs. 2, 2A) comprises a closed elongated duct 6 which is arranged over the grain to be transported and is connected at one end 8 to the grain outlet and is formed with a longitudinal slot which is covered with a movable mask (e.g. belt 5) at all positions ; and a connection piece 12 for the grain intake pipe, which piece is attached to the mask so that-the mask and connection piece move together to increase the range of the intake pipe. As shown, endless belt 5 passes over pulleys 1 and, at its lower run, serves as a movable mask to close a longitudinal slot formed on the underside of stationary duct 6. Through a gap in the belt enters the connection piece 12, the latter being secured to the belt so as to move therewith and the strain of its weight on the belt being taken (Fig. 3) by wheels 14 which support, through brackets 16 and springs 18, the connection piece 12. The edges of belt 5 hold tight against the flanges 6c of the duct 6 so that the latter is airtight and, when suction is applied at exit 8, the grain 19 (Fig. 4) in Saladin malting box 2 passes through intake pipe 12c, connection piece 12, duct 6, and outlet 8. Movement of connection piece 12 (Figs: 2, 2A). On the (static) duct is fixed twin chains 20 which are held stretched between brackets 23 by crosspieces 24 and springs 25. On the connection piece 12 is journalled wheel 29 and this is connected by sprocket 31, chain 32 to sprockets 26, also journalled on the piece 12. Hence, when hand chain 28 is tugged; sprockets 26 walk along chains 20 and cause the piece 12 together with belt 5 to accompany them. At the same time as the piece 12 and belt 5 begin to move, the movement of chain 20 causes member 37 to close air valve 35 and the movement of spring 25 causes relief valve 33 to open so that the suction is cut off from duct 6. This frees the belt from its tight adherence to the stationary duct and so allows belt and piece to move to the spot required. When this movement is finished, the tension in chains 20 ceases and the restoration of springs 25 restores the two air valves to their former positions and recommences the suction. The strip of belt 5 may be of limited length sufficient to cover the slot in the duct 6.
