Title: Improvements in or relating to cold-cathode gas-discharge tubes
Inventor: BACK RAYMOND RICHARD
IPC: H01J17/00
Filed: 1953-01-26
Abstract: 733,213. Cold-cathode tubes. HIVAC, Ltd. Jan. 13, 1954 [Jan. 26, 1953], No. 2227/53. Class 39 (1). In a cold-cathode gas-discharge tube of the type comprising a pellet of radio-active material to reduce the ionization time, the pellet is carried by a ceramic body which in turn is supported in suitable relationship to the main discharge path of the tube so as to direct the emitted alpha or other particles into the vicinity of such discharge path. The ceramic body reduces the heat conducted from the main electrodes to the pellet during the de-gassing process in the manufacture of the tube and prevents the pellet melting. The tube shown comprises a roc anode 15 surrounded by a tube 14 of glass or other insulating material extending from the pinch 11. The active end sur face of the anode 15 is sunk slightly below the end of the tube 14 and lies substantially coincident with the mid-point of the length of a cylindrical cathode 13 which is supported by two rods 12 sealed into the pinch 11.. A radioactive pellet 17 is located in a recess 18 formed by a counterbore in a short tubular ceramic body 19 mounted on the rods 12. The pellet 17, which is in the form of an inverted cupshaped capsule containing the active material, may have an underside layer of gold and an upperside layer of silver, and is retained in the recess 18 by a mica disc 21 which also divides the space in the tube into two regions. A gettering disc 22 is mounted on the rods 12 in the region above the mica disc 21 with its plane parallel to the longitudinal axis of the tube envelope and may readily be heated by an induction field without risk of materially heating the radio-active pellet. In a modified . construction a second ceramic body, identical in shape with the body 19 but inverted in position, is mounted on the rods 12 below the cathode 13 with its counterbore resting on the shoulder of the tube 14 and serves to locate the cathode 13 with respect to the anode 15.

Filed: 1950-01-30
Abstract: 691,180. Stereoscopic picture projection. FILIPPI, A. Jan. 30, 1950, No. 2304/50. Class 97 (i). For viewing projected stereoscopic pictures a line screen of plane mirror elements is interposed between the projectors and a projection screen and a second projection screen is disposed, symmetrically with the first with respect to the line screen, to receive the reflected light, observers being positioned so as to view both projection screens, one through the line screen and one by reflection from it. In the arrangement shown, the line screen S is vertical and the viewing screens El, E<SP>2</SP> are oppositely inclined so as to intersect its plane in the plane Q of the observers. The mirror elements of the screen S taper and converge towards a point in the line of intersection. In another arrangement the screen E<SP>1</SP> is inclined somewhat forwardly and the screen E<SP>2</SP> lies almost in the plane Q, the screen S bisecting the angle between them. The screen S may be a rearsilvered glass mirror from which silvering has been removed where required. A similar sheet of plane glass is placed behind to compensate for refraction effects. If the silver layer reflects on both faces viewing may be effected from the side opposite to the projection side. The mirror strips may have black margins to allow more latitude of eye position. Pseudoscopic vision may be prevented by covering the spaces between the strips with polarizing or analglyphic filters of alternating effect.

Title: Improvements in or relating to optical transmission systems
IPC: H04B10/60
Filed: 1969-05-20
Abstract: 1,274,951. Optical filter; laser radar. SIEMENS A.G. 20 May, 1969 [21 May, 1968], No. 25555/69. Headings H4D and H4F. To receive selectively an optical signal of narrow bandwidth #f of the order of 1 GHz or less (1 KHz in some cases), e.g. in telecommunications and radar, a substance 4 having an inhomogeneously broadened absorption line in the signal frequency range is subjected to a primary radiation of frequency and bandwidth substantially equal to that of the optical signal, to selectively saturate substance 4 and therefore provide an absorption window, so that the signal may be simultaneously, or within the relaxation time of the window, selectively filtered by the substance. The primary radiation may be varied in frequency to shift the middle frequency of the pass band and may be derived from the same source as the optical signal. A coloured glass filter and/or an interference filter may be used to augment the filtering action. In the radar shown, pulsed light from a laser 1 passes through a polarization modulator 9, a Kerr cell 10 and the substance 4 to selectively saturate it. Reflected light 6 arrives back at the substance 4 after the end of the laser pulse but while the substance is still saturated and simultaneous application of a pulse to the electrodes of the cell 10 causes deflection of the light at 9 towards a detector. Another radar embodiment, Fig. 2 (not shown), uses continuous transmission and reception of laser light, the reflected signal crossing the substance 4 in a direction at right angles to the direction of the transmitted priming radiation and being detected by a photo-cell. Both embodiments use a gaseous substance 4 with an absorption line broadened due to molecular movement (the "doubling" effect) and require that the band #f is centred at the maximum of the absorption line.
