Title: Method and apparatus for adjusting the colour purity of a colour  picture display tube
IPC: H01J9/44
Filed: 1971-04-19
Abstract: 1339970 Colour television tubes PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 19 April 1971 [10 April 1970 12 Sept 1970] 26468/71 Heading HID [Also in Divisions H3-H5] A method of adjusting the colour purity magnet of a colour television tube comprises scanning the screen with one or more unmodulated beams whilst a magnetic field is provided adjacent the screen, and adjusting the purity magnet until there is a constant colour over a predetermined area. Prefereably the field is provided by a coil 2, Fig. 9, which is centrally disposed over the screen 1, and with only the "red" electron gun operating the purity is adjusted until a red ball appears at the centre C. If the tube construction is such that the electron landing areas should not be centrally positioned on the luminescent spots in the centre of the screen, the adjustment may be such that the red ball appears on the 5 o'clock- 11 o'clock axis at a predetermined point which may be indicated by reference marks. A similar process may be used to position the deflection yoke using two circular coils positioned with their centres on the ends of the horizontal axis of the screen (Fig. 7, not shown); the yoke is adjusted until the red balls lie on the horizontal axis. To avoid coils overlapping the edges of the screen, the auxiliary coils 2<SP>1</SP> and 2<SP>11</SP> may be made semicircular, as shown in Fig. 9, and a further coil 2<SP>111</SP> amplifies the action of coils 2<SP>1</SP> and 2<SP>11</SP> to locate the red balls as near the edge of the screen as possible. Two guns may be operated to produce a yellow ball so that the deflection unit is correctly aligned for two colours. After the adjustments have been made to the purity magnet and to the deflection yoke, the coils may be energized through a thermistor with alternating current to degauss the shadow mask (Fig. 10, not shown). Permanent magnets may be used instead of coils.

Abstract: 1,172,889. Die-casting machines. G. G. PEKROL. 8 June, 1967, No. 26532/67. Heading B3F. A die-casting and trimming machine comprises a turntable 54 rotatable incrementally through a mould station 44, where a casting 48 is formed to become attached to the turntable, and a trimming station 126 where the casting is trimmed and separated from the turntable to drop on to a convyer 149 and the trimmings fall on to a conveyer 154 to be passed back to a molten metal pot (156), (Fig. 2, not shown), that feeds the mould. The mould comprises a movable top part having a cavity 26, said part being movable by a piston and cylinder assembly (16), (Fig. 1, not shown) and linkage (28), (30), (38) that slides a member (20) along vertical guide rods 12. The bottom stationary part of the mould includes a cavity 46 and has ejector pins 72 pressure cylinder operated through rack and pinion 76, 78, and shaft 80. The turntable has straight side edges 56 that align within a recess 50, 52 in the bottom mould part when the turntable is lowered prior to a casting operation. When molten metal is fed to the mould cavity via a sprue 58 that is heated by elements 62, metal also flows into a notch 60 on the turntable 54 to attach the casting 48 thereto. The trimming means comprise a support plate 146, having an opening 147 through which a separated casting 48 falls, and a trimming element 152 which is carried on an arm 148 attached to a rod 128 that is reciprocated, via rack and pinions 132, 134, 138, 140, by a piston and cylinder arrangement 144. In operation the mould cavity is filled when the turntable 54 is lowered, the ejector pins 72 withdrawn, and the top part of the mould securely clamped on to the bottom part. In this position a previously cast part 48 is lowered on to the support plate 146 for trimming. After solidification the top of the mould is raised and initially the ejector pins 72 and turntable 54 are raised simultaneously and then a lost-motion arrangement (90) allows the turntable to be raised further to lift the casting 48 off the ejector pins 72. The turntable is then rotated one increment by a piston and cylinder arrangement (122) via a ratchet assembly (Fig. 6, not shown).

The coil is carried by a head 16 on a shaft 15 which may be rotated by a motor 20 and may be raised or lowered by fluid operated means 17. The head also carries an annular quenching nozzle which projects fluid in the direction away from the coil. The work 23 is carried by a holder 22 mounted on rods 130 slidably engaging with a platform 21 carried by elevating screws 126. The rods 130 are carried by a yoke 134 which may be raised or lowered by fluidoperated means 135 which includes a further quenching nozzle adapted to be raised into the interior of the work. In a modification the work holder may be rotated during heating. Current supply to the coil is controlled by a switching transformer arranged in a casing 11, the primary coil being moved by the fluid operated means 14. The Induction coil 73, Fig. 7, is fed from the secondary coil through the shaft 15 and the surrounding sleeve 61 by means of circular brush connections. One brush is surrounded by a toroid form current transformer for indicating the value of the current. Capacities 32 are connected across the secondary by leads 31. Cooling liquid is supplied through the shaft 15 and circulates through the inductor and is sprayed on to the work through passages 118, 121, 122. When a work piece has been placed in position the work is raised and the induction coil is lowered until the coil is just below the bottom of the work. The primary of the switching transformer is now raised into operative coupling with its secondary and the work and the coil are moved in opposite directions.

[Class 110 (ii)] In a machine, such as a pump or compressor, of the kind comprising an eccentric rotor and a positively driven abutment oscillating about an axis parallel to the axis of rotation of the rotor, the abutment has a face extending on opposite sides of the axis of oscillation and having portions disposed substantially radially with respect to the axis of oscillation of the abutment. The abutment 8, Fig. 1, is pivoted on a spindle 9, and its actuating arm, Fig. 2, is operated by a connecting rod 13 attached to a crank-pin 11 which is concentric with the rotor 4. There is a slight clearance between the abutment and the rotor periphery, of the order of one to several hundredths of a millimetre. An arcuate portion 15 of the abutment forms a slide valve in co-operation with the delivery port 16. Preferably, the rotor has a stepped shoulder 18 to sweep away solid particles and dust, and the portion 19 may be machined to the same radius as that of the inner periphery of the chamber 1 so as to make arcuate contact therewith. The portion 19 may be grooved as shown.. In a modified construction, Fig. 6, one or more valves 22 communicating with the inlet 7 may be provided to enable the commencement of the pressure cycle to be delayed by opening one or other of the valves. Cam levers 24 are provided for this purpose. The valves 22 may take the form of arcuate slide elements applied against the external face of the chamber 1. A valve 17<0> may be disposed in parallel with the slide valve 15 to enable discharge to commence before the opening of port 16. A valve 17<00> may be disposed in series with the slide valve 15 to enable discharge to cease before the closing of port 16. The Specification as open to inspection under Sect. 91 comprises a construction, Fig. 1 (Cancelled), in which one end of a resilient blade 25 is clamped between a rigid plate 27 and a recessed surface 26 of the abutment, and the other end is free to deflect under the influence of the opposing pressures acting on its two sides for the purpose of effecting a variation in the valve timing in accordance with pressure conditions. To balance the rotor, which is of lighter metal than its shaft, that portion of the latter which passes through the rotor is offset. This subject-matter does not appear in the Specification as accepted.
