Title: Deflection circuits

Filed: 1959-06-12
Abstract: 849,195. Cathode-ray tube circuits. RADIO CORPORATION OF AMERICA. June 12, 1959 [June 25, 1958], No. 20253/59. Class 40(7). In a television CRT display the vertical (yield) deflection wave is amplified by a magnetic amplifier whose high frequency input is derived from the horizontal (line) deflection wave. As shown in Fig. 1 the magnetic amplifier 40 comprises a toroidal magnetic core 42. The output from the vertical timebase generator 38 is applied through a choke 46 to a high-inductance input winding 43 and horizontal timebase flyback pulses from the horizontal timebase amplifier 34 are applied through a limiting resistor 62, transformer 64 and coupling capacitor 66 to a low-inductance output winding 44 connected in series with an inductive load 52 such that the inductance of the output winding 44 is inversely proportional to the current in the input winding 43, the amplitude of the line-frequency signal in the load 52 being thus directly proportional to the input current. This amplitude modulation is detected by a rectifier 48 and capacitor 54 and applied to the vertical deflection winding 50 of the CRT 26. A D.C. biasing current is applied to the output winding 44 from a battery 56 via an inductor 58. In a modification, Fig. 2, the magnetic amplifier 80 comprises a pair of iron cones 82, 83 with series-connected input windings 85, 87 wound in opposite directions and series-connected output windings 84, 86 wound in the same direction or vice versa. The vertical timebase generator comprises a low-power neon oscillator connected to the input windings 85, 87 and a horizontaldeflection waveform 79 from the cathode of the horizontal deflection amplifier 76 is filtered by an R.C. circuit 90, 88 to give a corresponding sinusoidal signal which is applied to the output windings 84, 86. An adjustable D.C. biasing current is applied to the input windings 85, 87 by connecting one end of the windings to the H.T. supply 73 and the other end to earth through an adjustable resistor 92.

[Class 98 (i)] Photographic film packages of the type comprising inner and outer envelopes, the outer one of which is formed with a mask through which the light-sensitive material can be exposed when the inner envelope is withdrawn, has a flexible loop interconnecting the two envelopes in such a manner as to be drawn into the outer one as the two envelopes are separated to expose the film, and a locking tongue which, when the envelopes are closed, is insertable within the loop to prevent it collapsing and to prevent the inner envelope from being withdrawn. The complete package is shown in vertical cross-section in Fig. 5. The outer envelope, Fig. 1, comprises three panels, 12, with slot 17 ; 13, with exposure aperture 15, and 14. The sensitive material is placed on the panel 14, secured by bending over the tongue 18, and then folded over the aperture 15. The panel 12 is then folded over and secured by adhesive to the tongue 23. The tongues 20, 22 and 24 are folded inwards for light-tightness. The two sides of the plain inner envelope 10, Fig. 4, pass between the panel 14 and the panels 12 and 13 respectively. A tongue 30 attached to one side at the open end passes through the slot 17 and is secured at 31. When the looking tongue 32 is passed through the loop thus formed, the envelope 10 cannot be withdrawn. According to the Provisional Specification, the tongue 23 and panel 12 may be secured without the use of adhesive by a series of overlapping and interlocking portions, one of which may be the locking tongue 32. Specifications 445,611 and 452,013 are referred to.

Abstract: 459,869. Switchgear structures. REYROLLE & CO., Ltd., A., Hebburn-on- Tyne, and ALLAN, A., Cragside, Ashleigh Grove, Tynemouth. July 16, 1935, No. 20282. [Class 38 (v)] Metal-clad switchgear is arranged in panels disposed side by side and respectively associated with the individual circuits, each panel comprising a group of single-phase, liquidinsulated breakers one for each phase mounted one above the other in the front of the gear, and fixed chambers behind the breakers containing the connections from the breaker contacts to the associated circuit, thus providing economy of floor space without necessitating undue increase of headroom. Three single-phase, horizontally-withdrawable, oil breakers J are placed one over the other in front of the gear to constitute a panel, and a number of panels are arranged side by side, each being allocated to a feeder or other circuit. The movable contacts N<3> are carried on brackets N<4> which are carried by the operating mechanism O, and the several operating mechanisms are releasably linked at O<2> to a common operating rod O<1> whereby each breaker may be unlinked and run out for inspection purposes. The platforms K are apertured at K2 so that the top J4 of the tank J<1> of the withdrawn breaker may readily be removed for inspection of an arc-control device N containing the fixed contact. The latter and the contact N<3> are in sliding engagement with conductors L, L<1> which extend through bushing insulators M, M<1> into engagement with socket contacts P<2>, Q<2>, located in orifice insulators P<1>, Q<1> in the fixed oilfilled feeder and bus-bar chambers P, Q, respectively. Isolating and earthing switches P<3>, Q<3> for contacts P<2>, Q<2> are actuated from a common rod S<2> through the rod S and lever S<1>. An earthing switch T for the contact U<2> of each cable U is connected to a common rod T<1> which is suitably interlocked with rod S<2>. Breakers of the character disclosed in Specification 459,868, can be used and can be fixed to the gear, isolation being then effected solely by switches. In Fig. 1 (not shown), there is diagrammatically illustrated an arrangement in which isolation is effected solely by horizontal withdrawal of the breakers. In this form also the breakers are of slightly modified construction and a current transformer is arranged in each feeder chamber. The Specification describes forms of arc-control device employed in both constructions of gear.
