Title: Improvements in or relating to electron discharge devices incorporating electron lenses
IPC: H01J29/62
Filed: 1957-08-16
Abstract: 821,295. Cathode-ray tubes. WESTERN ELECTRIC CO. Inc. Aug. 16, 1957 [Sept. 7, 1956], No. 25972/57. Class 39(1). To eliminate deflection defocusing, two or more electrons 26, 27, Fig. 2, having elongated apertures with mutually perpendicular axes are interposed between two or more further electrodes 25, 28 having circular apertures. Electrodes 26, 27 are each supplied with a variable potential from their respective coordinate voltage sources 32, 34, for example by non-linear circuits 31, 33. Thus the correct amount of astigmatism is introduced to compensate the deflection defocusing produced by electrodes 16, 17. Electrodes 25, 28 are maintained at a high potential, e.g. 1000 volts above the cathode, and electrodes 26, 27 at lower positive potentials so that the arrangement acts as a unipotential lens. Dimensions and electrode spacings for one particular embodiment are given. The apertures of electrodes 26, 27 are preferably elliptical, having a major to minor axis diameter ratio of about 1À3, and the four electrodes being equally spaced at a distance of the order of the minor axis diameter of the elliptical apertures. The lens arrangement 15, Fig. 1 is used in a barrier grid storage tube in which 16, 17 are deflection electrodes and the beam scans a target assembly 20, comprising back plate 22, dielectric sheet 23, and a barrier grid 24. Information is stored in the form of a charge pattern by modulating plate 22 while the target is being scanned, and may be retrieved by again scanning the target and collecting the modified secondary emission from the target by means of electrode 18.

Title: Process and apparatus for the manufacture of moulded articles from mortar or concrete
IPC: B28B21/20
Filed: 1930-09-03
Abstract: 366,544. Moulding concrete &c. FREYSSINET, E., 28, Rue St. James, Neuilly - sur - Seine, France.-(Assignee of Seailles, J. ; 280, Boulevard Raspail, Paris.) Sept. 3, 1930, No. 26324. Convention date, Sept. 4, 1929. [Class 87 (ii).] Mortar or concrete, saturated with water, is introduced into a mould provided with one or more extensible mandrels of which the volume can be varied by a fluid under pressure, and is first subjected to vibration to settle it, and then compressed by admitting the fluid under pressure to the mandrel. The vibration may be continued or discontinued during the compression. For producing hollow bodies such as posts, pipes, &c. the mandrel A, which may be formed of rigid material such as steel or of wood having an elastic rubber coating, is introduced into the two-part mould B and the intervening space is filled with wet concrete C. The filling may be assisted by vibration. The excess water is evacuated through the joints of the mould, or material D, such as plaster, is placed in the mould to absorb it, or a porous plug E of clay is inserted. Instead of causing the mould to vibrate as a whole, vibratory waves may be transmitted to the fluid in the mandrel A. The mandrel may be placed in any part of the mould or may form the outer surface of the article while the mould forms the inner surface. When high pressures are used the mould may be supported in a press. Specification 181,745, [Class 87 (ii), Moulding plastic &c. substances], is referred to.

Title: Improvements in or relating to sliding roofs on vehicles
IPC: B60J7/185
Filed: 1949-10-15
Abstract: 678,566. Sliding roofs. WEATHERSHIELDS, Ltd., and BISHOP, W. H. Oct. 13, 1950 [Oct. 15, 1949], No. 26504/49. Class 108(i) A sliding roof is of the type in which an opening in the front part of the fixed roof 11, Fig. 1, may be closed by a longitudinally sliding panel 10 which when open slides under a fixed canopy 13 forming the rear part of the roof. The type also comprises a handle 34 for operating locking means for the panel, and means for raising the rear edge of the panel when closing to bring it flush with the canopy or for lowering the panel so that in the open position it may slide under the canopy. A roof of the above type has the panel 10 co-operating with a watercheck frame 12, Figs. 2, 3, the frame having a flange 14 carrying a tacking strip 15 for the roof lining. The front end of the panel, Fig. 2, is guided at each side by a felt lined slide 16 pivotally mounted by means of a pin 17 between lugs 18, 19 of the panel. Each rebated side 21 of the panel carries a flexible rubber sealing strip 22 engaging a flange 25 of the fixed roof. In the closed position the front edge 27 of the panel, Fig. 1, makes a seal with a rubber member 28 secured to the front edge of the fixed roof 11, and the rear end of the panel is provided with a channel 38 in which is mounted a rubber bead 39 adapted to engage with a seating 40 on the canopy. Adjacent to the rear end of the panel on each side, Fig. 3, a bracket 30 carries a felt pad 32 sliding in the frame 12, and a pad 33 is fixed to the flange 31 to locate the panel laterally against the flange 14. The handle 34 when rotated operates linkage to move a transverse bar 35 (Specification 528,454 is referred to for this mechanism). When the panel is closed. cranked arms 36 of the bar 35 are aligned with abutments 37 in the frame 12, and the angular movement given to the rod forces these arms against the abutments to raise the panel. In this closed position the pads 32 move through gaps 41 in the flanges 14. In a partly open position of the panel the arms 36 are urged against the bottom of the watercheck frame to hold the pad 32 against the flange 14 and prevent movement of the panel. The rearward opening movement of the panel is limited by a spring-loaded upstanding cranked portion 43 of a rod 44, which cranked portion may be turned down into the horizontal plane by turning the other cranked end 46 of the rod. When it is desired to remove the panel the crank 43 is turned and the panel slid back so that the front slides 16 may be raised through the gaps 41. The front end of the panel is then drawn forwardly and upwardly until the rear pads 32 may also be raised through the gaps 41 to free the panel.

Abstract: 682,037. Load-handling apparatus. SUNDIN, E. O. Nov. 2, 1950. No. 26760/50. Addition to 654,418. Classes 78 (ii), 78 (iii) and 78 (iv). In a hydraulic lifting jack according to the parent Specification, a control valve for the supply of fluid to the lifting cylinder and the two cylinders for swinging the lever 4<SP>1</SP> of the jack consists of a body which is rotatable and axially displaceable in a housing and is coupled to a control lever by means of a control rod, the control lever being mounted for pivotal adjustment in two vertical planes at right angles to each other. The valve body consists of a sleeve 27 which is secured by a pin 30 to the control rod 13. A control lever 18 is pivoted at 20 to each end of the rod 13 and has an extension which is connected by a link 16 to a collar 14 rotatable on the housing 1. The sleeve 27 consists of a thick portion divided by a peripheral groove 31, and a thin.portion, of the same external diameter so as to leave an annular space 55 between the sleeve and rod 13. An axial passage 26 in rod 13 connects space 55 with the space to the left of the sleeve. An axial passage 28 is also cut in the thick portion of the sleeve. The thin portion of the sleeve is perforated as set out below. A pin 29 in the rod 13 works in an opening 10 in the right of the housing which is sealed off from the valve proper. In operation lever 18 is moved to place pin 29 in one of the recesses c, d, e or f, or between the upper row of recesses and the lower recess f. In the latter or neutral position oil from a pump flows through a conduit 13<SP>1</SP> to inlet 24, through ports 3 and an opening in the thin sleeve portion, along space 55, through port 8 and back to the pump via conduit 38. In each of position c, d and e the space 55 is eut off from the opening 3. In position d fluid flows through groove 31, port 4, a non-return valve 32, and conduit 34 to the cylinder 1<SP>1</SP> thus raising lever 4<SP>1</SP>. In positions c and e fluid flows through port 2 along passage 28, and through groove 31 to one or other of the ports 5 which are connected by conduits 35, 36 to the swinging cylinders 14<SP>1</SP>. As the piston 14<SP>11</SP> of one cylinder 14<SP>1</SP> is extended the other piston 14<SP>11</SP> retracts and fluid passes through the other port 5 and either directly through a hole in the thin sleeve portion, or through axial passage 26, to the space 55 and hence back to the pump. In position f the oil from the pump is again by-passed through port 3, space 55 and port 8, and, in addition, fluid is allowed to escape from cylinder 1<SP>1</SP> via conduit 34, a pressure reducing valve 40, conduit 37, port 6, and a hole in the thin sleeve portion, so lowering lever 41.
