Title: Improvements relating to grid structures, particularly suitable for colour cathode ray tubes
IPC: H01J9/14
Filed: 1956-12-21
Abstract: 847,506. Colour television tubes. GENERAL ELECTRIC CO. Dec. 21, 1956 [Dec. 21, 1955], No. 38963/56. Class 39(1). Vibration in operation of the wires of a focusing and colour switching grid adjacent to the screen of a colour receiving tube is damped, and the wires held in correct spaced relation, by a filament 15 of vitreous material extending transversely across the wires at their central region, the filament being interlaced between the wires and being heated during assembly to cause the material thereof to soften and bend about the grid wires to the shape of Fig. 5. If desired heating may be continued to cause the vitreous material of the filament 15 to flow so as to partly embed the grid wires therein, as shown in Fig. 6. The wires are preferably stretched during the heating, to make the operation more rapid and with less heating, by two combs 16 carried by a bar 17, the ends of the wires being secured to a frame 11 by cement 12, and radiation heating of the filament is effected by an electrically heated wire 19 energised controllably by source 20 secured at one end to handle 23 and tensioned by weight 21 at the other end. The frame 11 and cement 12 are preferably electrically conductive so that the grid wires are call connected together ; the frame may however be non-conductive if the cement is conductive. The wires can be divided into a plurality of sets at different potentials. The filament can have a thickness of 1¢-2 mils and be made of glass having a sticking potential of 6kV. In assembly, the grid wires are stretched on a frame 11, the tensioned filament is interleaved between the wires and heated so that the tension of the wires stretches the filament to the form of Fig. 5, followed by the desired further heating, Fig. 6, and then by cooling and setting. The wires are held by the teeth of combs 16 during heating and cooling. The screen has phosphor stripe triodes and there are 3 guns, one for each colour. In a modification, Fig. 7, the opposite ends of the grid wires are supported on arcuate ledges 27 as described in copending Specification, the 3 colour screen and grid structure also being arcuate. The heating filament 38 is also arcuate and is supported by insulators 29 so as to ensure more uniform heating. It is stated that the invention can be applied to any discharge tube in which the vibration of grid wires is to be damped. Specification 841,832 is referred to.

Title: Improvements in and relating to the thermal treatment of synthetic filaments
Inventor: DITTRICH WOLFGANG
IPC: D02J13/00
Filed: 1967-08-24
Abstract: 1,145,928. Heat-treatment apparatus for filaments. SPINN-UND ZWIRNEREIMASCHINENBAU KARL-MARX-STADT, VEB. 24 Aug., 1967, No. 38996/67. Heading B5B. An apparatus for the thermal treatment, especially heat-setting, of synthetic filaments comprises two heating plates 1, 2 arranged one above the other which form a passage between them for the filaments to be treated, at least one of said plates being pivotable into a non- operating position, wherein the pivotable heating plate is rotatably seated on its pivotal support and means are provided to effect a compulsory rotation of the heating plate simultaneous with its pivoting movement. The heating plate may be rotatable in a direction opposite to the direction of pivoting of its pivotal support. Thus as shown, the heating plate 1 is linked for rotation at its mounting 4 with a pinion 11, which is engaged by the toothed portion 12 of a rack 13, whose mounting 16 is offset in relation to the mounting 7 of the pivotal support 5 in such a manner, that on pivoting of the heating plate a relative movement takes place between the pivotal support 5 and the rack 13 which leads to the rotation of the pinion 11. Sleeve 15 is loosely pivotable about the mounting 4 of the heating plate 1 which is traversed by the rack 13 and which holds the toothed portion 12 in engagement with the pinion 4. The two heating plates 1, 2 may be pivotable and rotatable in opposite directions. The two pivotal carriers 7, 8 of the heating plates 1, 2 may be coupled for oppositely directed movement, e.g. by means of toothed wheels (not shown). As shown in Fig. 3, during their pivoting the two heating plates 1, 2 may be rotated through different angles. The compulsory rotation of the heating plates 1, 2 during their pivoting movement can also be realized in a different manner, thus e.g. by hingedly connecting each of the two heating plates at two points with their pivotal supports 5, 6 and their racks 13, 14 respectively, so that the heating plates 1, 2 constitute in practice a four hinge connection.

Title: Improvements in or relating to means for detecting a predetermined stage in the titration of two liquids
Inventor: MONK PHILIP REGINALD
IPC: G01N31/16
Filed: 1959-11-17
Abstract: 971,150. Utilizing radiation detectors. BAIRD & TATLOCK (LONDON) Ltd. Oct. 12, 1960 [Nov. 17, 1959], No. 39010/59. Heading G1A. In an apparatus for determining a predetermined stage, e.g. the end-point, in the titration of two liquids, the liquids are passed to a mixing chamber 2 and cell 4. A beam from a light source 13 is directed through the cell 4 to a part-silvered mirror 18 which splits the beam into two parts. One of these passes through a filter 21 to a photo-cell 23, while the other passes through a filter 24 to a photo-cell 26. Filter 21 has a pass band at the absorption band of the mixture of the two liquids before the end-point, and filter 24 at that of the mixture after the end-point. The photo-cell outputs are compared in aunit 31 which controls the operation of a relay unit 32. A valve 9, which controls the flow of one of the liquids into the chamber 2, is closed by unit 32 at the end-point. Instead of passing liquid direct into the chamber 2 from valve 9 the liquid may be passed into the pipe connecting the chamber and the cell 4. The liquid added in this way is sufficient to take the small amount of mixture in the cell past the end-point, so that valve 9 is caused to close. However as more mixture flows from the chamber to the cell the mixture in the cell is no longer fully titrated, so valve 9 is opened again. These operations are repeated until a true end-point is reached. Specification 853,469 is referred to.

Filed: 1974-08-02
Abstract: 1473837 Arc extinguishing DEFENCE SECRETARY OF STATE FOR 2 Aug 1974 [23 Aug 1973] 40013/73 Heading H1N To ensure that the contacts of a vacuum switch will be fully open at the moment of initial arc extinction, the current is monitored by a detector with a monostable pulse generator arranged to provide an output pulse of predetermined duration to a coincidence gate when the current rises above a threshold value. If this pulse coincides with a tripping signal, contact separation will be initiated, the timing being such that contact separation will be completed when the current has reached zero. Three single phase switches 12-14 are mounted in the supply lines 6-8 and current is monitored by CTs 9-11, which feed through low pass filters 15- 17 and rectifiers 18-20 to threshold detectors 21-23 which are also fed with a reference current to act as comparators, this reference current being set at a value greater than the minimum are-sustaining current for the switch. Thus whenever the current through a line conductor rises through this threshold value the comparators will produce a signal pulse of predetermined duration through the monostable pulse generators 24-26. The duration of this pulse is such that there is sufficient time from its termination to the instant when the current falls again below the are-sustaining value for the switch contacts to open fully. This signal from the pulse generators is fed to AND gates 27-29 which also receive signals from any of the tripping sources associated with the switch-gear, so that if both signals coincide the switch in the associated line will be tripped. A monostable 30 may be inserted in the tripping signal line if there is a likelihood of the tripping signal being brief or intermittent. In a modification for simple systems wherein a substantially fixed load is to be connected into a relatively low impedance network, the current transformers are replaced by voltage transformers and the current is derived from the phase relationship.
