Title: Scanner with radiation converting components
IPC: H04N3/14
Filed: 1966-05-04
Abstract: <PICT:1121726/C4-C5/1> An electroluminescent device is used to produce a scanning beam of radiation.  Fig. 2 shows an equivalent circuit of the device which may be a composite semi-conductor device (Fig. 1, not shown) having gallium arsenide or phosphide type light emitting sources 29, producing the scanning beam.  The operation of the circuit of Fig. 2 is described with reference to its function in investigating a radiation pattern 64 (see Division G1).  In this investigation, a signal is produced through amplifier 50 at terminal 52 representing the radiation falling on the detectors 29A-29F, which are made effective repetitively in sequence by feeding in signals from source 54 to give a repetitive scanning of the radiation pattern.  In operating the device to emit radiation, the devices 29A-29F, now light-emitting sources, are made effective in sequence by means of source 54, but the amplifier 50 is used to vary the brightness of the emission by varying the current through the sources 29A-29F. The construction of the semi-conductor device is described in detail (see Division H1). The sequential activation of the sources 29A-29F is produced by the connection of the respective sources, through control diodes 28A-28F to two voltage gradients 46, 48, which can be varied by a sweep or sinusoidal signal from generator 54.  The back-biasing on the diodes 28A-28F which normally prevents activation of the sources 29, is removed in sequence by this variation.

Title: A process for ascertaining the degree of the absolute or relative resistance to rusting shown by iron, steel and iron alloys
IPC: G01N17/00
Filed: 1927-07-28
Abstract: 292,794. Mauler, C. July 28, 1927. Testing, - A process for ascertaining the resistance of iron, steel &c. to rusting, used in the manufacture of rustless steels, consists in immersing the specimens in an alkaline oxidizing solution, which is kept in a boiling condition and noting the temperature at which the first signs of corrosion appear, the temperature having a definite relation to the concentration of the liquid. It has been found that steels which require a high concentration of the boiling liquid are those which exhibit the greatest degree of resistance to rusting. Conveniently, the specimens are removed from the liquid and examined at each degree of increase in the boiling point. The solution consists of an alkali, such as caustic soda or potash, and an oxidizing agent, such as a nitrate, permanganate, bichromate, peroxide or an aromatic nitro compound. To this solution is added some of the solution left from a previous test and containing the solid reaction products. In an example, 60 to 70 kilogrammes of caustic soda are dissolved in 20 to 40 litres of water together with 8 to 15 kilogrammes of sodium nitrate, 1 to 3 litres of the reaction products referred to above and, to maintain the alkalinity constant, 1 kilogramme of slaked lime for every 100 litres of the solution, the boiling point of which is approximately 140<0> C.
