Title: Oscillator signal amplitude compensation means
IPC: H03B5/18
Filed: 1974-08-13
Abstract: 1464727 Transistor oscillator RCA CORPORATION 13 Aug 1974 [24 Aug 1973] 35624/74 Heading H3T  An oscillator having a resonant LC tuned circuit coupled to a first electrode of a 3 electrode amplifying device has feed back to the 3rd electrode including a rectifier to sustain oscillations and the rectifier further, provides for charging a capacitance in the tuned circuit and for reducing the amplitude of the oscillations fed back when a first polarity portion of the oscillations exceeds a predetermined level. A UHF oscillator has a transistor 26 with an RF choke in its collector coupled to a tap 32 on a transmission line conductor 20 tuned by a varactor 16 supplied with variable tuning voltage from potentiometer 50. Blocking capacitor 18 and 34 isolate the inductor to D.C. A diode 48 couples a further tap 46 to the emitter, and is connected to be non-conductive, acting thereby as a capacitor. A charge storage capacitor 22 connects the low impedance end of the inductance 20 to earth, and a resistor 56 is connected to allow controlled discharge of the capacitor 22. The output signal is taken from a loop 58 coupled to the inductor 20. If the amplitude of oscillations rises sufficiently the diode 48 starts to conduct on the positive peaks and this acts to charge the capacitor 22 to a negative voltage. This negative voltage increases the reverse voltage across the diode 48 thereby decreasing its capacitance and so reducing the amplitude of the signal fed back to the emitter and consequently reducing the amplitude of the oscillations in subsequent cycles. The transistor is brased by resistors 38 and 40 to be conductive. The oscillator is intended to be placed in a shield 12 with feed through capacitors to decouple the supply leads.

Title: Improvements in or relating to the measurement of moisture
Inventor: HERBERT JOHN MARTIN
IPC: G01N27/12
Filed: 1955-12-12
Abstract: A humidity-sensitive element consists of a thin slice of a solid foam material consisting of a polymeric organic insulating material which can absorb moisture from the air, made conductive by the incorporation therein of finely distributed carbon.  Example 1.-Alkaline xanthated cellulose derived from 100 parts by weight of dry raw cellulose was mixed with 10 parts of chopped hemp fibre, 55 parts gas black, 500 parts hydrated sodium sulphate (ground to pass through 50 mesh per inch screen).  The mixture was packed into perforated moulds and heated in a sodium sulphate solution to decompose the xanthate and leach out the sodium sulphate.  This produced a crude sponge which was treated with acid, washed out with water and dried.  The dried sponge was then immersed in paraffin wax and cooled to room temperature and slices 0.002 inch in thickness cut from it by means of a microtome.  The slices were washed in xylene to remove the wax and then with ether alcohol and water.  The cleaned slices were held between brass clamps one inch wide with a gap of one eighth of an inch between them.  Example 2.-Xanthated cellulose derived from 100 parts by weight of dry raw cellulose was mixed with 25 parts of undissolved cellulose fibres and 60 parts of gas black. To this mixture 6 times the volume of hydrated sodium sulphate was added.  The mixture was then heated in a near-saturated solution of sodium sulphate to decompose the xanthate and leach out the sodium. The sponge was then treated as in Example 1.  But the slices cut by the microtome were 0.003 inch thick.  The changes in resistance of the sensitive element may be measured by making it form one arm of a resistance bridge circuit.

[Class 136 (ii)] In a back-pedalling brake for pedal-driven vehicles, the braking pressure is applied to a drum, provided with one or more wedge-shaped grooves on its outer surface, by a corresponding- shaped split band or series-of segments adapted to be pressed on to the drum by members which do not rotate relatively to the band or segments about the axis of the drum. In the form shown in Figs. 1 and 2, the sprocket wheel 4 is mounted by ball bearings 3 on a member 2 screwed on the hub 1, and drives the member 2 and hub 1 through a free-wheel device 5. A ring 6 is also screwed on the hub 1, and is provided with an annular groove 7 (or several such grooves) of wedge-shaped cross-section in which engage brake segments 8 of similar cross-section, spaced apart under the action of interposed springs 9, Fig. 2. The outer surfaces of the brake segments 8 are formed with inclined cam recesses 10 to receive rollers 11, which, on back-pedalling, move up the cam surfaces and force the segments 8 inwards to apply the brake. The brake segments 8 are prevented from rotating by screw-studs or pins 12 engaging radially-elongated openings in a ring 13 which is rigid with an arm 14 anchored to the cycle fork. In a modification, the ring 13 is connected to the arm 14 through a freewheel device,.in order to permit the cycle to be wheeled backwards.' The outer end of the ring 6 may be connected to a copper &c. disc adapted to dissipate the heat of braking. The invention may be applied to a hub having several' sprockets for a change-speed gear.

Title: Improvements relating to electric discharge tubes, particularly gas-filled luminous tubes
IPC: H01J61/16
Filed: 1934-12-20
Abstract: 449,031. Discharge apparatus. SCHALLREUTER, W. L. W., 89, Scrubs Lane, Willesden, London. Dec. 20, 1934, No. 36486. [Class 39 (i)] A discharge device, particularly a luminous discharge device, having a filling comprising one or more common gases or vapours and at least one of the gases hydrogen, helium, neon, argon, krypton or xenon, is so constructed that the positive column or arc is separated from the cathode negative glow by a capillary restriction. A separation of the constituent gases is set up, the inert gases collecting near the electrodes and shielding them from attack by common active gases such as carbon dioxide. In one form, Fig. 1, the electrode chamber C is separated from the main envelope by a porcelain capillary tube R. For greater convenience in manufacture, the tube R may be secured within a uniform tubular envelope by a trap joint, as shown in Fig. 2. The capillary tube may be replaced by a disc having a fine hole. The electrode E may alternatively be enclosed in a sleeve ending in a capillary tube R, Fig. 6. The capillary tube may be of quartz, magnesia, steatite, porcelain, graphite or metal. The electrode may be of cold cathode type in the form of a hollow cylinder, or of self-heating thermionic type in the form of a narrow cylinder coated internally with emissive material. In a modification, the electrode E, Fig. 7, has itself a capillary opening R at the end small enough to prevent the formation of a negative glow within the opening, which thus separates the negative glow within the electrode from the positive column. The outside of the electrode is prevented from glowing by a coating of alumina, or by a sleeve of porcelain slipped over it. A capillary tube “ to 1 inch in length may have a diameter of 1 mm., while a simple aperture may be À5 mms. in diameter. The filling may comprise mixtures of helium, argon, or neon with nitrogen or carbon dioxide, or a mixture of neon, hydrogen and carbon monoxide which gives a " wriggle " effect, optionally with the addition of mercury. Fillings of neon and hydrogen, helium and hydrogen, helium and cadmium, and of hydrogen, argon and carbon dioxide, are referred to.

Title: Improvements in converting ammonium sulphite-bisulphite into ammonium sulphate and sulphur
IPC: C01B17/06
Filed: 1938-12-20
Abstract: 511,673. Ammonium sulphate; sulphur. I. G. FARBENINDUSTRIE AKT.-GES. Dec. 20, 1938, No. 37053. Convention date, Dec. 24, 1937. [Classes 1 (ii) and 90] A process for the conversion of acid ammonium sulphite solutions into ammonium sulphate and sulphur by heating at elevated temperatures is characterized in that the solutions are partially oxidized preferably up to 15-20 per cent. of sulphate with gases containing oxygen before conversion. Suitable solutions may be obtained by catalytically converting the hydrogen sulphide in gases such as coke oven gas into sulphur dioxide and washing out the latter together with the ammonia contained in the gases. The oxidation may be carried out by allowing the solution to trickle down a tower provided with filler bodies while air is blown up, or finely divided air may be forced into the solution. In the case of solutions obtained from gases from roasting processes and ammonia the roasting process may be controlled or the gases may be diluted with air so that the solution contains sulphate at the start. The oxidation process may be assisted by increased pressure or temperature. In order that gases are not given off during the oxidation step the ratio of ammonia to sulphur dioxide should be between 1 : 1 À 8 and 1 : 3. The solutions are preferably acidified after oxidizing and then boiled in autoclaves, the maximum pressure produced being from 8 to 9 atmospheres as opposed to the 18 to 20 atmospheres of the process without the oxidizing step.
