Title: Plant for the feeding of pulverulent or granular materials
IPC: G01G11/08
Filed: 1960-08-02
Abstract: 910,509. Automatic feed control systems. SOC. GRENOBLOISE D'ETUDES ET D'APPLICATIONS HYDRAULIQUES SOGREAH, and BOUDAN, J. Aug. 2, 1960 [March 29, 1960], No. 26716/60. Class 38 (4). The supply of pulverulent or granular material to, or the speed of, a weighing type endless conveyer is controlled in dependence on the time integral of the product of the weight of the conveyer and the speed. In Fig. 1 pulverulent or granular material in a silo S is supplied by means of an extractor E to a weighing-type endless conveyer T driven by a geared motor MR. A signal dependent on the weight of the conveyer, derived from a weigher D, and a signal dependent on the speed of the conveyer, derived from a speedometer t, are multiplied together in a regulator unit R in which the difference between the product and a desired value of the product derived from an adjustable unit AF, serves to control, through a servomotor SM, the rate of feed of extractor E. Regulator R developes and adds an integral component of control. The system maintains constant the mean rate of supply of material by conveyer T. The signal from unit AF may be varied in dependence on a physical variable or in accordance with a programme. A plurality of conveyers, having separate automatic regulating systems, supplying materials to form a mixture, is referred to.

Title: A process for impregnating thick textile products with latex under great hydraulic pressures
IPC: D06M15/693
Filed: 1932-09-30
Abstract: Thick textile products, such as jute boot soles, ropes, are impregnated with rubber by forcing latex into them at a pressure of 50-800 atmospheres.  The latex is treated to increase its viscosity, and to stabilize it to reduce friction and prevent coagulation during impregnation.  Gum arabic, tragacanth, karaya may be employed, but neutral saps of cactus, particularly Nopal cactus are preferred. Castor oil soap, with or without linseed or like oil, may also be added.  Alcohol mixed with soap to prevent a tendency to premature coagulation, may be added to the latex to facilitate penetration.  5 per cent of waterglass prevents the latex from exploding.  A gas generating substance such as ammonium carbonate is also added to the latex to enable water to escape from the interior on drying.  A suitable mix consists of 80 parts of latex (60 per cent solids), 15 parts of Nopal cactus sap, 5 parts of castor oil soap, 3 parts of a 5 per cent solution of ammonia, 5 parts of alcohol in soap, 6 parts of waterglass, 6 parts of linseed oil, 4 parts of ammonium carbonate, 2 parts of sulphur, 6 parts of zinc oxide, 0,5 parts of "Vulcacit P," 0,5 parts of "Vulcacit 774," and 0,5 parts of diphenylguanidine.  The fabric &c. must be free from acid, and is treated if necessary with sodium carbonate.  When the impregnation, the pressure and time of which depends on the thickness and texture of the article, is completed, the surface is cleaned, alcohol is applied to form a coagulated skin, the p  article is warmed to generate gas and drive off water, pressed to compact the rubber, and vulcanized. Specification 316,335, [Class 140, Waterproof &c. fabrics], is referred to.

Title: Improvements relating to the manufacture of composite cast metal rolls
IPC: B22D19/16
Filed: 1936-10-07
Abstract: In a composite roll the core metal may comprise steel with a tensile strength of 286 tons per square inch or iron containing 1,8-3,2 per cent of carbon, 1,5-0,2 per cent of silicon, 0,2-1,5 per cent of manganese, up to 1,5 per cent of chromium, up to 1 per cent of molybdenum and up to 3 per cent of nickel if desired.  The metal for the chilled shell may comprise iron containing 3-4 per cent of carbon, 0,2-1 per cent of silicon, 0,2-8 per cent of manganese and, if desired, up to 10 per cent of one or more of nickel, molybdenum, vanadium, tungsten, and titanium.  If steel is used as the core metal the roll must be annealed at, say, 930-940 DEG  C. for six hours and, to avoid softening, the shell should be made of a ledeburitic base alloy.  The silicon content should, therefore, be kept as low as possible and iron containing about 3,8 per cent of carbon, 0,27 per cent of silicon, 1,25 per cent of manganese, 1,6 per cent of chromium and 0,17 per cent of nickel has proved satisfactory.

The fashioning screws are of opposite thread and one set of pawls rotates them in one direction and the other set in the opposite direction. Nut housings 16 are mounted on the fashioning screws to move the fashioning mechanism by means of bars 17, 18, 20. Switch boxes 63 are provided with a rotatable lever 72 which is set adjacent a cam roller 73 on the nut housing as the nut housing moves away the lever 72 is rotated and remains in the rotated position. The position of the lever 72 determines the direction in which the nut housings are to be automatically returned to the starting position after a garment has been completed. The pawls 25, 26, Fig. 2, are driven through a lever 35 and rod 43. A parallel system of rod 53 (not shown) and lever 52. operates the bluff plates. The abutment of the lever 52 against the end of a lever 58 determines the amount of bluffing to take place. The lever 58 is pivotted to vary the angular movement of the lever 52 and this determines whether the mechanism shall move one or two needlewidths or remain stationary.

Title: Improved means for producing high-frequency electric vibrations or oscillations more particularly for transmitting messages
IPC: H03B11/06
Filed: 1921-10-15
Abstract: 190,577. Habann, W. E. E. Oct. 15. 1921. Converting alternating and direct currents.- In a system for producing high-frequency electric oscillations, particularly for transmitting messages, air waves of a trequency exceeding 4000 are caused to act on a microphone or other vibratory body which is arranged to excite an electric oscillation circuit. The air waves are produced by a Galton whistle having an adjustable nozzle 16 and adjustable tube 17. The vibratory body or microphone comprises a diaphragm 1, Fig. 3, of from 4 to 20 m.m. diameter, with a thickness cf 0.01 to 0.05 m.m., and a contact-pin 2 with a rounded end resting against the diaphragm. The pressure between the pin and the diaphragm can be varied by adjusting either the pin or the diaphragm. In the arrangement shown, the pin is fixed and the diaphragm-carrier 5 is adjusted by means of worm gearing 6, 7. The contact-pin may be rendered incandescent, or the contact surface may be ionized by radium preparations. The microphone is mounted with its trumpet 13 opposite the mouth of the whistle, the distance of the microphone from the whistle, being adjustable. The whistle may be blown at a lower frequency than that which it is desired to use, the higher harmonics of the fundamental frequency being caused to act on the microphone by means of an adjustable reflector 27 carried by a pivoted arm 30. Other means, such as a resonator, may be used instead of the diaphragm microphone, and a reed-whistle or eiren may replace the Galton whistle. For multiple transmission, a siren with concentric rows of perforations co-operating with a series of microphones may be used. Magnetic. frequency converters may be used for multiplying the frequency obtained by the microphone. An application to telephone circuits is shown in Fig. 4. The microphone is connected to the terminals 10, 11 in series with a battery Z, the microphone circuit being connected by an adjustable coupling P to an oscillating circuit S tuned to the acoustic frequency. Low-frequency speaking currents are led to the microphone circuit by a transformer T and are there divided into high-frequency impulses adapted to be transmitted through the oscillating circuits S to a long-distance line F or to an antenna. The speaking currents may be amplified, if necessary, before reaching the microphone, in which case the amplifying valve may serve as a limiting tube to prevent overloading of the microphone contacts.
