Patent GB-1381018-A (GB)
Title: Inline electron gun
IPC: H01J31/20
Filed: 1972-05-23
Abstract: 1381018 Electron guns RCA CORPORATION 23 May 1972 [14 Jan 1972] 24107/72 Heading H1D An electron gun for a colour television tube of the shadow mask type, comprises means for generating three co-planar parallel beams and lenses in the path of each beam for focusing and converging the beams near the screen. In Fig. 4 the parallel beams are produced by the cathodes 37, control grid 27, screen grid 29, and first accelerating anode. Converging electric fields for the two outer beams are produced by displacing the outer apertures 73b of the second accelerating anode 33 about 6 mils. outwards relative to the co-operating apertures 67b in the first anode; the apertures 67 and 73 may be about 160 mils. and 172 mils. in diameter respectively. The large size and small spacing of these apertures may distort the beams into elliptical shapes and this distortion may be minimized by making the wall 69 barrel-shaped with radii of curvature of 8 inches in the plane of Fig. 4 and of 2À28 inches in the plane normal to Fig. 4. Coma distortion (different raster sizes) due to the eccentricity of the outer beams in the magnetic deflection field may be corrected by surrounding the outer apertures 87 in the shield cup 35 with shield rings 89 of magnetic material to cause a slight weakening of the magnetic field, and a further correction may be applied by providing discs 91 of magnetic material on each side of the central aperture 85 normal to the plane of Fig. 4. The electrodes are all mounted from two parallel glass rods (outlined at 23) the ends of which extend into recesses (outlined at 95) provided in the shield member 35.

Title: Analogue signal transmission system
Inventor: PRICE JACK RICHARD
IPC: H04Q9/06
Filed: 1964-06-10
Abstract: 1,114,522. Electric selective signalling. ENGLISH ELECTRIC CO. Ltd. 9 June, 1965 [10 June, 1964], No. 24142/64. Heading G4H , In a system for transmitting measurements from a plurality of out-stations to a central station an address code selects a particular out-station to transmit, and a power supply from the central station permits that station to transmit. In the illustrated embodiment a combination of two state potentials, representing the address, on a plurality of conductors operates a diode gating arrangement at an out-station to permit a transistor switching circuit energized by the central power supply to operate a relay and close switches connecting transducers having analogue output signals to meters having indicating dials at the central station. Corresponding address switching units are included at the central station to permit operation of that dial corresponding to the transmitting station. Each station may transmit different measurements simultaneously on separate lines, the power for the transmitting transducers being supplied from the central station. The receiving dials are looked in position after each transmission. Monitoring units may be incorporated in the switching power supply and the receiving circuits to detect incorrect operation. The measurements may be recorded on a paper-tape together with the addresses of the transmitting stations. Control units at out-stations may be operated by closure of appropriate contacts at the central station by the address-switching unit, the central control being effected by adjustable rheostats. A similar addressable system may be included for transmitting data from the central station to the out-stations.

Abstract: 337,850. Green, A. Aug. 15, 1929. Winding-machines; stop-apparatus, non-automatic.-In a machine such as described in Specification 326,786 or in machines for winding cops of yarn or thread, wherein the spindles are frictionally driven, the thread guide is carried by an arm 9, Fig. 3, which is frictionally held on a rotatively oscillating shaft 10 and which is advanced round. the shaft 10 by impacting against a progression wheel 19. The winding spindle 3, which may carry a tapering tube 4, Fig. 5, is driven by friction discs 5, 7, a friction washer 3c being pressed against a collar 3b by a spring 3a. The progression screw 17 is spring mounted eccentrically in a bush 2d in which it is held in operative position by an arm 17m having a sleeve fitted over the spindle 3. When the cop is wound, the arm 17a is withdrawn from the spindle and rotated half a turn in the bush 2d, thereby moving the screw 17 and wheel 19 away to allow the cap to be taken off. The screw 17 may have rather more than half its thread cut away along the whole length to enable the wheel 19 to be slipped back to the starting position. For removing the cop, the spindle 3 and delivery are stopped, a rod 20, connected with a rod 20b, is moved upward by a hand-operated stop-motion, the friction disc 7 and thel spindle 3 being moved in its bearing 2, away from the driving disc 5 by a projection 20c acting on the disc 7 and against the pressure of a spring 8; the delivery being stopped by a stud 20d engaging an arm 16a of a lever pivoted at 16c and forcing the de,- livery roller 16 away from the roller 15a against which it is normally pressed by a spring 16b. The traverse arm shaft 16 is oscillated by a cam driven by a chain and gearing from the driving shaft, the cam rocking an arm fixed to the shaft 10. The wheel 19 may have a tyre 19a of rubber, leather & c.

Tempering.-To obviate losses of the hardening liquid during the thermic treatment of steel &c., as described in the parent Specification, a determined quantity of liquid is added to the bath during the harder treatment of the steel &c. The additional liquid is supplied by an horizontal pipe 1, the quantity being regulated by a valve 3 so as to maintain the bath 2 full up to the outflow 4 or so as to prevent the temperature rising beyond a specified value according to the required hardness of the steel &c. The parts of the material immediately above the pipe 1 will thus be cooled more rapidly than the other parts. The additional liquid may be hot or cold. The Specification as open to inspection under Sect. 91 (3) (a) states that the additional liquid may be supplied by sprinkling, especially when it is desired to treat certain parts of the steel &c. This subject-matter does not appear in the Specification as accepted.

Classes 79(1) and 79(2) A power driven twowheeled tractor adapted for the removable attachment of implements has independent oscillatory and rotary power take off means for driving the implements independently of the motion of the vehicle. A vehicle driven by a petrol motor 13, Fig. 1, comprises a box like chassis 11 mounted on wheels 12 and having handlebars 15 to which throttle and clutch control levers 17, 18 are at tached. The oscillatory power take-off means comprises a saddle 49 which may be used to operate a mower 52 plugged to the chassis 11 by support bars 53 inserted into slots 54 in the front plate and locked by means of screws 56. Oscillatory motion is transmitted to an operating arm 51 attached to the reciprocable cutter bar of the mower and inserted through square shaped opening 50 in the saddle 49. The rotary power take-off means comprises a pulley 60, Fig. 4 which may be used with a belt 61 for driving a circular saw 63.

The discs 36, 37 are loaded by a spring 38 to provide a spring slip clutch which prevents damage to the machine in the event of the mower or circular saw meeting heavy resistance. A worm 40 in the shaft 33 engages a worm wheel 41 for driving the road wheels through a clutch (not shown), which automatically releases on overload. A skew gear wheel 42 on the end of the shaft 33 engages a gear wheel 43 on a power take off shaft 44 carrying the pulley 60.

Abstract: Nitrosamines are manufactured by the action of caustic alkali on diazonium compounds of 1-amino-4-nitrilobenzenes of the general formula <FORM:0481735/IV/1> where X and Y are substituents other than hydroxyl or solubilizing groups, or on the corresponding alkali syn-diazotates, if necessary at a raised temperature.  The products are intermediates for the manufacture of dyestuffs.  In examples: (1) 1-amino-5-methyl-2-chloro-4-nitrilobenzene is diazotized, the diazo solution is introduced into a cold potassium hydroxide solution, and the resulting syn-diazo compound is heated with a further addition of potassium hydroxide; (2) 1-amino-2 : 5-dimethoxy-4-nitrilobenzene is similarly treated, except that caustic soda is employed; (3) 1-amino-2-methoxy-5-chloro-4-nitrilobenzene is treated as in (1); (4) a diazo solution from 1-amino-2-methoxy-5-chloro-4-nitrilobenzene is introduced into a caustic potash solution at 50-60 DEG  C.; (5) 1 - amino - 5 - methoxy - 2 - diethylaminosulphonyl-4-nitrilobenzene is diazotized and the diazo solution is introduced into a cold caustic potash solution.
