Title: Display system utilizing beam shape correction
IPC: H01J29/52
Filed: 1975-09-30
Abstract: 1523304 Colour cathode-ray display tubes RCA CORPORATION 30 Sept 1975 [4 Oct 1974] 39964/75 Heading H1D A colour C.R.T. includes a colour selection electrode, a coplanar gun assembly for generating three beams, means for statically converging the beams at the screen centre, and a deflection yoke with H and V coils, the winding distribution of the yoke assembly producing a pin cushion H deflecting field such that the beams are converged along the H deflecting axis but which is also liable to cause the beams to be horizontally distorted when deflected horizontally from the screen centre, at least one grid electrode having vertically elongated apertures (e.g. elliptically shaped) forming elongated beam shapes at the screen centre for reducing horizontal distortion caused by the deflection assembly (cf. Fig. 7 (not shown), Fig. 5 (not shown) being prior art). A barrel shaped V deflecting field ensures convergence at all raster points and zero trap. Fig. 2a (not shown) illustrates the H deflection field providing horizontal axis convergence without additional dynamic convergence, and being the sum of two fields as in Figs. 2b, 2c (not shown). The fig. 2c field may be produced by the winding distribution (Fig. 8a), or as part of the yoke assembly, a quadrupole winding on the yoke, or a separate winding adjacent the yoke may ensure the non-uniform field for self convergence. Figs. 3a, 3b, 3c (not shown) illustrate corresponding V fields. Slight under- and overconvergence at the ends of the H and V axis of small screens may be necessary. For wide deflection tubes simplified dynamic convergence for one direction may be used, (e.g. producing the quadrupolar field of Fig. 4 (not shown). Also the deflection field centre may be aligned with the centre beam to ensure convergence balance around the screen edges, e.g. the yoke may be 1-3 mm. larger than the neck allowing transverse/tilting movements, or the Y and H scanning currents may be unbalanced by series impedance in one coil half, or by shunting the current. Such self-converging systems produce horizontally stretched beams, corrected by the above elongate apertures. Fig. 6a includes control grid 52, screen grid 53, first and second accelerating and focusing electrodes 54 and 55, and shield cup 56 spaced along glass rods 50. Dimensions and beam separations are given. Outer apertures 78R, 78B are slightly offset outwardly to focus the outer beams and deflect them to converge with beam 70G. The vertical cross-over of the principal rays of each beam is focused on the screen by adjusting the potentials of electrodes 54, 55. Both grids 52, 53 have elongate apertures (Figs. 6b, 6c, not shown). Ellipticities are exemplified. Fig. 1 (not shown) includes static convergence assembly 28 producing quadrupole or hexapolar fields, combined with or separate from colour purity device 29 of two rotatable ring magnets.

Floors of a building are heated by placing electric heating cables in spaced straight runs of metal tubes 1 to which are attached, e.g. by welding metal strips 2 extending longitudinally thereof, and a heat-distributing metal layer 20, e.g. of expanded metal is attached to the strips 2, the whole being embedded in a concrete floor. The heating cable preferably comprises a nickel-chromium wire insulated by asbestos from a lead sheath and is withdrawable from the tubes 1, which may be of steel. The straight runs of tube comprise each a number of tubes joined end to end by short steel tubes 3 having a central projection 4 and entering adjacent ends of the tubes 1, and these runs terminate at one or both ends in a metal trough 5 containing supply cables and terminal boxes and having a removable lid. The end .tubes are held against the trough by short metal tubes 7, each having a flange bearing against the 'inner trough wall and passing through this wall into 'the end of a tube 1. The straight runs of tubes 1 may be connected at one end by curved metal tubes 17 through which the heating cables pass. The curved tubes 17 are held in contact with the expanded metal 20. Spring clips 21 attaching the expanded metal 20 to the strips 20 may also enter holes closely spaced in a metal spacing bar 14 placed transversely across the runs of straight tubes to hold them spaced during assembly.

Title: Control valve suitable for use in fluid pressure brake systems
IPC: B60T8/18
Filed: 1959-12-04
Abstract: 880,894. Valves. BENDIX-WESTING- HOUSE AUTOMOTIVE AIR BRAKE CO. Dec. 4, 1959 [Jan. 30, 1959], No. 41297/59. Class 135. [Also in Group XXXIV] A control valve mechanism 22, for a vehicle braking system, supplies to an outlet port 26 a pressure reduced with respect to pressure at inlet port 20 whenever pressure at port 26 exceeds the pressure at a control port 32 connected to an air suspension spring or springs 36 of the vehicle, and includes a movable element 46 having an area exposed to port 32 equal in size to the difference between second and third areas exposed to ports 20, 26, respectively, and being operatively connected to valve means 62, 64, 66 which connect or disconnect ports 20, 26 depending on whether the force exerted on the third area is greater or less than the combined force on the first and second areas. Valves ports 20, 26, 54 are connected respectively to drivers control valve 10, brake cylinders 30 and atmosphere. Normally with the brakes released, the element 46 is lowered by pressure in cham- .ber 56, exhaust port 54 being closed and valve 60, 64 opened. On braking, should the air pressure delivered from the brake valve 10 to the brake cylinders 30 be greater than the air spring pressure (controlled automatically according to load) then the forces on element 46 cause closure of both valves 60, 64 and 54, 56. The brake cylinder pressure being less than the pressure in chamber 50 by an amount depending on the air spring pressure and hence the load. Should the air spring pressure be greater than the pressure delivered from the brake valve, then element 46 remains in the lower position and full pressure is applied to the rear brakes as if the valve did not exist. On reduction of pressure in chamber 50, element 46 rises to open exhaust valve 54, 66 and release the brakes; the pressure in chambers 50, 52 also equalizes via spring-biased valve 74 should the resultant downward force on element 46 cause valve 54, 66 to close before complete brake release. The front brakes may be applied directly from the brake valve or via a pressure-reducing valve as above.

Abstract: 1,103,648. Colour television. COMPAGNIE FRANCAISE DE TELEVISION. 26 Sept., 1966 [27 Sept., 1965], No. 42954/66. Heading H4F. To magnetically record on a single track a colour television video signal comprising a luminance signal and a sub-carrier frequency modulated by colour signals, e.g. a " SECAM " (Registered Trade Mark) type signal, the video signal is separated into two signals H and L by means of high- and low-pass filters, signal H including at least the modulated sub-carrier and signal L at least the low-frequency components of the luminance signal, and the two signals are combined and passed to a magnetic writing device after signal L has either frequency modulated a wave or has been attenuated to produce a signal L<SP>1</SP>. In the embodiments described signal L extends from 0 to 2 Mc/s. and signal H from 3.5 to 5.5 Mc/s., the video signal comprising a 5À5 Mc/s. luminance signal and a colour subcarrier extending from 3.5 to 4.8 Mc/s. In the embodiment in which signal L<SP>1</SP> comprises a wave frequency-modulated by signal L, the frequency band of signal L<SP>1</SP> comprises 0À2  Mc/s. to 3.3 Mc/s., the frequency modulating means including an output filter. The output of the magnetic recording device is passed to two filters having pass-bands corresponding to signals H and L<SP>1</SP> and the two resulting signals are combined after signal L<SP>1</SP> has been frequency demodulated. Since the reproduced luminance signal has suffered a loss of definition the output signal of the frequency demodulator may be crispened through differentiation of the signal. If the sub-carrier in the input video signal was submitted to a filtering in a coding filter the high-pass filters preferably include a decoding and a coding filter. In the second embodiment in which signal L<SP>1</SP> comprises an attenuated signal L, the subcarrier included in signal H acts as an auxiliary high-frequency bias oscillation, since as is known one method of recording low-frequency components comprises adding to this signal a bias sinusoidal voltage. Instead of attenuating signal L signal H may be amplified. The circuits preferably include a band rejection filter for the frequency band separating the bands of signals L and H.
