Title: Improvements relating to cathode ray storage apparatus
IPC: H01J29/18
Filed: 1963-11-05
Abstract: 992,178. Cathode-ray storage tubes. TEKTRONIX Inc. Nov. 5, 1963 [Dec. 19, 1962], No. 43576/63. Heading H1D. A cathode-ray storage tube includes a storage target having a secondary electron emissive, porous, phosphor layer supported over and integral with a light transparent conductive support member; writing means for producing a charge image and a light image on the phosphor layer; a source of low velocity flooding electrons for maintaining the charge image; and means for scanning a reading beam of electrons over the phosphor layer to produce a read-out signal on the conductive layer. The screen 26, Fig. 2, includes a phosphor layer 65, which may contain some magnesium oxide to increase the writing speed, and a conductive tin oxide film 58 which extends, on the glass endplate 60, out through the glass seal 64 to the ceramic funnel 62 to contact a silver lead 68 for the bias voltage and read-out signal. A silver coating 70, closely spaced from the screen, is biased to ensure that the low velocity electrons from flood guns 30 hit the screen normally. Adjustment of ganged switches 18, 24, 46 permits the use of cathode 28 for both writing and reading, the read-out signal across load resistor 32 being amplified and fed to T.V. monitor tube 36. In a further embodiment (Fig. 3, not shown) the provision of two separate guns permits simultaneous writing and reading. This embodiment also permits the storing of highfrequency transient signals which are faster than the writing speed-such that only a temporary image is formed by the writing beam-- by feeding back the amplified read-out signal to modulate the reading gun control grid, such that the reading beam itself produces a permanent image. Alternatively, a temporary image may be stored by passing the read-out signal to a second storage tube. In a further embodiment (Fig. 4, not shown) the conductive layer 58 is divided by a gap into two insulated portions provided with separate bias supplies, permitting their independent operation, whereby one area can be used to preview an unstored waveform before storing it on the other. A further gap in layer 58 may provide a third area which is itself divided into character-shaped conductive areas connected to separate bias supplies arranged to correspond to, and be indicative of, the vertical gain and horizontal sweep speed settings of the writing gun, whereby the graticule scale units corresponding to any display are automatically displayed on the storage tube screen, and on the monitor screen 36. Specifications 992,176 and 992,177 are referred to.

Abstract: 1,194,107. Stereoscopic projection systems. CARL ZEISS - STIFTUNG [trading as CARL ZEISS]. Sept. 13, 1968 [Sept. 23, 1967], No. 43620/68. Heading G2J. A projector for the stereoscopic display of a rotating sphere comprises a film-strip 3 bearing an image of the surface of the sphere in Mercator's projection, the strip being moved continuously at variable speeds past a field of view stop B exactly framing the circumference of the projected image, and a projection lens with elements I, II, III, having a strong pin-cushion distortion. These elements may be disposed asymmetrically about the enclosed stop B with concave outer faces facing the stop. Again, all elements may be in front of the stop. The section II of the projector carries the film feed mechanism and projection lens, and is rotatable about the optical axis by geared motor 13. This motion may be synchronized with the driving speed of a subsidiary fixed star projector when the sphere is a planet in a planetarium display.

Abstract: 1,180,078. Digital transmission systems. SIEMENS A.G. 29 Sept., 1967 [30 Sept., 1966], No. 44344/67. Heading H4P. Each digit in a data transmission system is transmitted as two simultaneous frequencies and is followed by a rest period in which two simultaneous preset frequencies are sent, each frequency of a pair being selected from a corresponding group of frequencies. The receiver monitors the received signals to detect faults occurring at the transmitter. In the embodiment described each digit is represented by two frequencies, each chosen from two groups of four frequencies, f1-f4, and f1, f1 is sent during the rest period The frequencies aregenerated by an LC oscillator in which capacitors are selectively switched across the inductor. The receiver monitors each time interval in which a digit and a rest signal should be received and indicates a fault if the combination f1, f1 is not detected during this interval, as would occur if the transmitter switches malfunction. The fault signal is passed to the transmitter to operate an alarm. If the digits are transmitted as a block of known length departure from this length, as determined by a counter at the receiver, will indicate that a fault has occurred at the transmitter, e.g. a rest signal has been sent instead of a digit, or vice versa.

Suitable monobasic fatty acids contain at least 7 C atoms and are preferably drying oil acids; they include linseed and dehydrated castor oil fatty acids, linoleic, pelargonic, lauric and 12-hydroxystearic acids; rosin may also be used. Other polycarboxylic acids may replace part of those named above, e.g. long-chain dicarboxylic acids and dimeric and tricarboxylic fatty acid derivatives. Suitable epoxy compounds are the glycidyl polyethers of bisphenol A, hydroquinone and resorcinol. Suitable neutralizing agents are NaOH and NH 3  and Et 2 NH, Et 3 N, mono-, di-, and triethanolamine, morpholine, dimethylaminoethanol, diethylaminoethanol, and isopropanolamine. The products may be dissolved in water which may contain, e.g., butanol, isobutanol, the monoethyl or monobutyl ethers of ethylene or diethylene glycol, methyl ethyl ketone, methyl isobutyl ketone, isophorone, cyclohexanone or petroleum distillates. In Examples epoxy resins are reacted in xylene with dehydrated castor oil fatty acids plus rosin, or with lauric acid, pelargonic acid or stearic acid, then with maleic anhydride, phthalic anhydride plus a maleinized fatty acid, or trimellitic anhydride or dodecenylsuccinic anhydride; the products are neutralized with diethylamine, triethylamine or NaOH, with or without previous addition of ethylene glycol monobutyl ether, then diluted with water.

Abstract: 919,958. Centrifugal separators. SEPARATOR A.B. Dec. 20, 1961 [Dec. 29, 1960], No. 45599/61. Class 23. A mixture of liquids having a limited solubility in each other is separated into its constituents in a centrifuge in which one of the separated liquids is discharged in a chamber 12 which is kept under vacuum and is in vacuum-conveying communication, e.g. through a slit 21, with a chamber 18 in the centrifuge rotor, from which chamber a mixture of air and of the other separated liquid is exhausted. The mixture of liquids is fed through a stationary tube 5 and flows through a distributer 6 into a set of discs 8 within the rotor 2 where separation takes place. The lighter component is conveyed via the inside of the top disc 9 into a chamber 10 and through holes 11 into the chamber 12 from which it is extracted by a pump 14. The heavier component is thrown outward of the discs and flows between the disc 9 and the rotor cover 15 and through channels 17 in the wall of the chamber 10 into the chamber 18 from which it is discharged through a paring disc 19 into a pipe 20. The paring disc also allows the air contained in the chamber 18 to be exhausted, thereby creating a vacuum in that chamber and in the chamber 12 under the influence of which particles of heavier liquid still in solution in the lighter liquid are evaporated. The liquids may be oil and water or an organic liquid and an organic extraction agent.
