Title: Improvements in or relating to grid structures for electron discharge devices
IPC: H01J19/38
Filed: 1946-07-13
Abstract: 628,562. Thermionic valves. STANDARD TELEPHONES & CABLES, Ltd. July 13, 1946, No. 21014. Convention date, Oct. 3, 1945. [Class 39 (i)] In an electron discharge device of the type in which the cathode, grid and anode are mounted upon annular rings spaced apart by glass collars forming part of the envelope, the grid structure comprises three or more groups of grid wires fixed to an annular ring. The wires of each group are nested one within the other and bent in a plane at an angle of 360 degrees/n, where n is the number of groups, and are fixed to the ring at their ends only, the bent portions of the wires being left unsupported, so that deformation of the grid wires out of their plane due to thermal effect is eliminated. As shown, four groups 16-19, of nested wires are. mounted on the ring 10. The emitting coating on the cathode is omitted from that portion opposite the central space 20. The Specification as open to inspection under Sect. 91 comprises also a grid made of radial inwardly-extending wires. This subject-matter does not appear in the Specification as accepted.

Abstract: 854,898. Indicating by radiation sensitive devices. NATIONAL RESEARCH DEVELOPMENT CORPORATION. July 9, 1957 [July 9, 1956], No. 21209/56. Class 40(3). [Also in Group XX] In the measurement of the density distribution of silver in a photographic image, particularly an X-ray diffraction photograph, in which the silver image is converted to a radio-active image the radio-activity from which is to be measured electrically, a permanent visible photographic duplicate of the silver image is prepared to provide a visual control for the scanning of the radio-active image by radiation detecting means. The silver may be converted to radioactive silver iodide by treatment with a solution of potassium ferricyanide and potassium iodide containing radio-active iodine. The measuring apparatus consists of a transparent cylindrical film-bearing drum 1 rotatable on bearings 2 and illuminated by a lamp 5. Slidable on guide rails 6 parallel to the drum 1 is a carriage 8 carrying a Geiger counter housing 9 movable over the radio-active image attached to the drum, and a telescope 13 correspondingly moved over the visible duplicate similarly attached to the drum. In a modification the two photographs may be mounted back to back on the same section of the drum which is slidable axially and rotatable to effect the scanning. Alternatively, the carrier may be a transparent sheet. The photographs may be held in position by suction.

Abstract: 1315472 Making containers of foamed plastics material S E M SOLLERLID 19 April 1971 [11 Feb 1970] 21408/71 Headings B5D and B5K Containers of rigid foamed plastics material are made by simultaneously heating the edge surfaces to be joined over their whole extension until a molten layer of predetermined thickness is formed and then pressing the edges together. As shown in Fig. 2, the side walls of a container are made from a sheet 11 of foamed plastics material inserted between a former 10 and an angle member 13 and folded into the position shown in Fig. 2 by flaps 14, 15 operated by piston and cylinder units 16a, 16b. The edge surfaces of the sheet 11 are simultaneously melted by a heating means 19, the means 19 are retracted by means of a piston and cylinder unit 18, the flaps 14, 15 are further pivoted by piston and cylinder units 17a, 17b to bring the edge surfaces into contact, the assembly 10, 13, 16, 17 is rotated anticlockwise and a pressing means 20 is brought into contact with the edge surfaces whilst they set. The blank 11 is then removed from the former 10 and, as shown in Fig. 5, placed in a former 22, 23, above which a bottom plate 25 is held by suction on a plate 24. The edge surfaces of the plate 25 and blank 11 are simultaneously melted by heating means 28, the means 28 are removed, the plates 22 and 24 are moved towards each other, and a pressing and shaping device 30 is brought into contact with the edge surfaces whilst they set. A top plate may be attached to the container in a similar manner. In a modification, the surfaces of the heating means 28 may comprise alternating ridges and valleys which provide the edge surfaces of the sheets with a larger molten area for joining. The foamed plastics material may be foamed polystyrene or a laminate of foamed polystyrene and foamed polyethylene.

Abstract: 359,431. Snapaction switches; drum controllers. T. S. MOTORS, Ltd. and DINE, E. H., Victoria Works, Maidstone, Kent. July 16, 1930, No. 21519. [Classes 38 (iii) and 38 (v).] Contacts.-As the contact arm of a switch comes to the end of its throw it is pressed against one part of a lever mechanism through which the contacting surfaces are pressed into contact with a considerably increased pressure. A drum controller 1 operates through a lost-motion device 20 to push or pull a connecting-rod 2 to cause a contact 4 on an arm 3 to engage either the contact 6, or the contact 6a of a change-over switch. A link 15 is pivoted at one end to the pivot 5 of the contact-arm 3, and is connected at the other end 14 to a link 13. A tension spring 10 connects the end of the link 13 to the contact-arm 3. The connecting-rod 2 is connected at 14 to the junction of links 13, 15 so that on moving the rod to the right the spring 10 is carried past the dead-centre position moving the contact-arm 3 across to engage the contact 6a. Projections 16 on the link 13 co-operate with the forked end 17 of the rod 2 to assist in throwing over the spring. The contact 6 is mounted on the shorter limb of a pivoted bell-crank lever 7 and is pressed downwards by a leaf spring 9. When the moving contact 4 first comes into contact with the contact 6 the latter is raised until a projection 8 on the lever 7 meets the contact-arm 3 and further movement serves to increase the contact pressure.

A hand pump for mounting on a container comprises a cylinder 10 with a flange 70 for engagement by a container cap, and a plunger 22 with an outlet 26 and inlets 48 controlled by a portion 38 of a sleeve 30 reciprocable in the cylinder with the plunger. In the extended position of the plunger, as shown, vents 14, for admitting air to the container, are closed by a beading 33 on the upper end 32 of sleeve 30 sealing the space between plunger 22 and a collar 16 on cylinder 10. In this position, inlets 48 are closed by engagement of the lower edge 44 of sleeve portion 38 with plunger enlargement 42. Stops 58, 60 limit outward movement of the plunger. On depression of the plunger, the lower edge 44 of sleeve portion 30 disengages from enlargement 42 and upper edge 40 engages plunger abutment 36, continued depression of the plunger moving sleeve 30 downwardly to discharge the cylinder contents via inlets 48 and outlet 26, vents 14 having been opened by disengagement of sleeve end 32 from collar 16. On the upward stroke by spring 54, check-valve 50 opens to admit liquid from dip tube 52, and inlets 48 are closed by sleeve edge 44 engaging enlargement 42. Plunger 22 is of reduced diameter between abutment 36 and enlargement 42 to prevent sliding contact with sleeve 30. A bead 31 on sleeve 30 slidably engages the cylinder. A removable cap 72 has internal ribs 76 for engaging ribs 74 on a skirt 66 on collar 16. Web 64 between skirt 66 and collar 16 is resilient to accommodate cap tops of different thicknesses between skirt edge 68 and cylinder flange 70.

The diameter of a crystal that is being continuously formed is controlled by a system in which the interface 29 with the melt is optically imaged at 30 and any change in contrast between the freezing interface image and the melt image is used to vary means 18 for pulling the crystal, and/or means 22 for raising the melt. The contrast is detected by two photo-cells 35 connected in a bridge circuit with a balancing potentiometer Fig. 2 (not shown). They are arranged so that one is half illuminated by the interface and the other by the melt; thus the output of the first photo-cell depends upon the position of the interface and hence the diameter of the crystal. The output of the bridge is amplified to control the speed of pull rod motor 19 and, via a second potentiometer, a motor 22 which raises the crucible 17 at a rate (adjusted by the second potentiometer) which keeps the interface in focus. The crucible is also rotated and the output of the bridge is shunted by a capacitor to eliminate short term variations due to this rotation, and the speed of rotation may also be controlled by the bridge output.
