Abstract: 1,267,408. Cathode ray tube circuits. R.C.A. CORPORATION. 19 May, 1969 [22 May, 1968], No. 25376/69. Heading H4T. In a television receiver utilizing a cathode-ray tube 14 the quiescent voltage between a cathode and a control grid of the tube during the horizontal retrace period is maintained relatively constant, despite the uses of an unregulated voltage supply + V cc  to bias the pulse-operated grid clamping circuit and to energize the cathodedriving portion of the luminance channel and a pulse-generating circuit for operating the clamping circuit, by the presence of voltage regulating means, such as a Zener diode 25, across a voltage divider 26/27 to which the pulses are applied, thereby maintaining the pulse amplitude substantially constant. In the colour receiver illustrated each of three clamping circuits comprises a resistor/diode series combination such as 62/63 connected across the divider 26/27 which forms part of the collector load of a transistor 32 in the pulse-generating circuit. The transistor 32, normally biased off via components 30, 31, is pulsed on during the horizontal retrace periods by a large negative retrace pulse from the deflection circuits 13 applied to its emitter. The clamping pulse is consequently applied across the divider 26/27, its amplitude being regulated by the Zener diode 25, which may be provided with a radiation-suppressing circuit 24/51. The luminance signal is supplied to the cathodes through a drive transistor 16 energized by the supply + V cc . The base drive of the transistor 16 is from a low level luminance amplifier 12 powered by a low voltage regulated supply.

Abstract: 579,954. Hot air and gas power plant. AKT.- GES. FUR TECHNISCHE STUDIEN. Dec. 28, 1944, No. 25974. Convention date, Dec. 29, 1943. [Class 7 (i)] [Also in Group XXVII A power plant in which a gaseous working medium is compressed, heated from an external source and then expanded in a turbine is regulated by removing or supplying working medium to the plant in accordance with changes of load and to prevent hunting, when sudden changes of load occur, a fraction of the quantity of working medium which has to be supplied or removed for complete regulation is suddenly removed from or supplied to the high pressure side of the system, the remainder being supplied or removed over a longer period. In the plant shown the working medium is compressed in a compressor 1 heated at 2, 3 and expanded in a turbine 4. Connected to the high pressure side of the system at 6 are two valves 7, 8 which control the supply to the system from reservoir 10 and removal from the system to reservoir 9 of working medium 1. The valve 7 is operated by a centrifugal governor 11 and removes fluid from or supplies it to the system in the normal manner as the speed of the plant rises or falls. The valve 8 is connected by a dashpot 16, 18 to a device 14 which takes up a position corresponding to the load being taken from a generator driven by the plant. On a sudden change of load occurring the dashpot piston is driven down quickly and operates the valve. If only a small change of load occurs the valve is not operated since a leak hole in the piston enables the oil to flow through to the other side. Other means of operating the valve 8 dependent on acceleration or the change of torque in the shaft connecting the turbine to the generator are described. An alternative arrangement is shown in which the valve 8 is operated by the centrifugal governor through a dashpot which only operates when there is a sudden change of speed. In a modification the working medium removed from the high pressure side of the plant 11 by the valve 8 is returned to the low pressure side. The valve 8 may further be used as a safety valve for closing down the plant quickly if the speed or pressure of the plant exceeds a safe value.

Title: Improvements in and relating to the production of aluminium fluoride and the double fluorides of aluminium and ammonium
IPC: C01F7/788
Filed: 1933-09-20
Abstract: In the production of aluminium fluoride, solid aluminium hydrate is intimately mixed with such an amount of a solid acid fluoride salt of ammonia that it contains at least six and preferably twelve atoms of fluorine for each molecule of alumina used, and the mixture heated at 100--200 DEG  C., until a double aluminium ammonium fluoride is formed, after which the temperature is gradually raised to 500--600 DEG  C., to decompose the double salt and yield anhydrous aluminium fluoride.  If desired, the second heating step may be omitted and the double fluoride recovered as such.  The initial materials may contain free or hygroscopic moisture.  Vapours evolved in the second heating step are collected and reformed into ammonium acid fluoride for re-use by combination with hydrofluoric acid; for instance they may be first passed through aluminium hydrate to remove ammonium acid fluoride and then into aqueous hydrofluoric acid.  The ammonium acid fluoride may be prepared in situ as by using normal ammonium fluoride in the initial mixture, or by mixing aluminium hydrate with an ammonium compound such as the carbonate, and heating the mixture in the presence of hydrofluoric acid gas.  The process may be carried out continuously in an externally heated rotating tube having a temperature gradient of 150--600 DEG  C., which contains initially a charge of ammonium acid fluoride.  Hydrate of alumina is fed into the cool end of the tube and hydrofluoric acid at the hot end.  In the furnace the double salt is first formed and then decomposed at higher temperatures, and the vapours evolved react with the hydrofluoric acid to form ammonium acid fluoride which condenses at the cool end of the tube and reacts with further supplies of aluminium hydrate. The process may be carried out in aluminium vessels, or in the case of the continuous process, also in vessels constructed of iron or steel.

Abstract: 939,157. Telegraphy. CREED & CO. Ltd. July 6, 1962, No. 26058/62. Class 40 (3). In an apparatus for sampling received start-stop telegraph signals means is provided for selecting the instant in each bit period at which sampling shall take place. The selection may be manual, or controlled automatically by the monitoring apparatus. In the embodiment described, reception of a start pulse enables gate G 1 to permit generator PG to send pulses to binary counter BC. The pulse rate is 128 pulses/ bit. After counting 64 pulses, i.e. after one half-bit period, an additional stage F4 is used to form a sevenstage counter, counting to 128. The counter output is converted by bistable units to a monophylic code and its complement, and these signals are impressed on gates G9-G22. The instant at which sampling is to occur is selected by 128-position switch MS which gives an output in monophylic code. Its output is fed to the gates G9-G22 either direct or through inverters R2-R8. The gate assembly acts as a comparator so that a pulse is provided to open gate G32 each time the counter has counted to the desired count. The pulse samples from gate G32 are distributed on to lines 47-51 and passed to stores prior to use in a printer or tape punch. Specification 934,341 is referred to.
