Title: Intelligence transducing beam modulation method and apparatus
IPC: H04N1/405
Filed: 1970-02-18
Abstract: 1313771 Facsimile systems AMPEX CORP 18 Feb 1970 [20 Feb 1969] 7734/70 Heading H4F In a facsimile or other display system an analogue signal is converted to a pulse width modulated signal comprising transition delimiting consecutive pairs of intervals, of which the aggregate duration of each pair is constant and of which the intervals within each pair are modulated in duration complementally, by comparison with a ramp signal (linear, convex or concave) of a frequency at least twice that of the highest frequency of the analogue signal which is to be reproduced, and the pulse width modulated signal is used to switch a beam of radiation between a high and low or zero intensity level, e.g. that from a C.R.T. Appropriate choice of ramp shape and limiting voltages compensates non-linearity in the system and the use of pulse width modulation means that the gamma characteristic of the C.R.T. does not affect reproduction. The modulated signal may be (a) used to switch an oscillator on and off, its output being coupled via a transformer and detector to a C.R.T.; (b) sent via a transformer to a full wave rectifier feeding a bi-stable controlling the C.R.T.; (c) passed via a light emitting diode to a detector controlling the C.R.T. Such circuits are said to be useful when operating with a " depressed " cathode, i.e. anode at earth potential.

Title: Photographic copying process
IPC: G03F1/00
Filed: 1951-04-03
Abstract: 697,036. Photographic copying processes. HEIDENHAIN,J. April 3,1951,No. 7748/51. Drawings to Specification. Class 98 (ii). [Also in Group XV] A process for the production of images, characters, measurement graduations, or the like on supports as of glass, metal, and plastics, by the photographic reproduction of an original, is characterized in that a light-sensitive layer capable of being washed out by developing is applied to the support, exposed imagewise by contact or projection by means of the original, and then parts are washed out; image-forming substances are deposited by vaporization on the support and on the exposed parts of the lightsensitive layer; and said exposed parts are thereafter removed together with the substances deposited thereon, so that the deposited substances remain only on the unexposed parts, corresponding in form to the original. The light-sensitive layer with which the support is coated may consist of bichromated albumen, shellac, or the like, and after exposure the unhardened parts are washed away, leaving the support bare. The substance deposited by vaporization on the support and the remaining parts of the layer may be a metal such as chromium, silver, or copper; a salt such as magnesium fluoride or another fluoride; other inorganic compounds such as silicon monoxide or dioxide, or an organic substance. Vaporization may be carried out in vacuum, and different substances may be deposited simultaneously or in succession; e.g. first chromium and then silicon monoxide. The remaining light-hardened layer is then removed as by a solvent, together with the deposit thereon, leaving the deposit only on those parts which were exposed to light. If the light-sensitive layer is bichromated shellac and the substance deposited is chromium, the chromium is treated with nitric acid to render it resistant to the action of caustic soda, and the light-hardened shellac is removed with a weak solution of caustic soda in methylated spirit. If desired, a second substance may be deposited by vaporization on the support and the remaining deposited substance; further, the first substance may be dissolved away, leaving the second substance only on those parts of the support not previously covered by the first substance. The first deposit could, e.g. be formed of silver, and the second substance could be chromium; in this case the silver would be dissolved by nitric acid.

Filed: 1942-06-10
Abstract: 559,331. Cathode-ray tubes. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. June 10, 1942, No. 7922. Convention date, May 9, 1941. Drawings to Specification. [Class 39 (i)] To prevent "ion spot " and " smudge on the luminescent screen of a cathode ray tube-more particularly those using sulphide phosphors-the phosphor is coated with (i) a thin ion barrier layer to prevent ion migration across the phosphor and (ii) on top of this barrier layer another layer of a thickness of 20 to 100 Š to absorb the ionic bombarding energy. These two layers are penetrable by electrons and are non- luminescent. For the first layer barium, aluminium or caesium may be used as they act chemically with the migrating ions ; or beryllium silicon or aluminium provides resistance to ion migration as these materials have a closely packed molecular structure ; lithium or beryllium fluoride, beryllium nitride or silicon carbide or dioxide also may be used for this layer. The second layer is thicker than the first and may be of aluminium oxide. The two layers are deposited by vaporization of materials mounted in the tube. The intermediate barrier layer may be dispensed with if aluminium oxide is used as the bombarding energy absorbing layer, as this gives a barrier-phosphor interface which inhibits migration of the ions. The phosphor may be zinc, cadmium or zinc cadmium sulphide, zinc or zincberyllium silicate arranged in layers or mixtures.
