Abstract: FIELD: die casting and cooling of blanks of foundry products. SUBSTANCE: device uses a plate serving for movement of blanks from the casting zone that are extracted from the mould and held in it. The mentioned plate may have heat exchange devices designed for cooling of the outer surfaces of foundry products or blanks and a system of controlled cooling of the inner surfaces of foundry products or blanks. The device for cooling of products has two sections with a different amount of heat. The foundry product is extracted from two halves of the mould and transferred to the holder on the end of a lever mobile robot and mover to the second position of the closed mould. In the process of this movement the discharge nozzle of the cooling pin is inserted in the inner cavity of the foundry product being in the holder. An open system with a duct for outlet of the gaseous refrigerant supplied through the inner cavity of the foundry product to the environment is formed between the cooled pin and the foundry product. The gaseous refrigerant is fed through the inner duct of the cooling pin stretching up to its discharge nozzle. At an insertion of the cooling pin in the foundry product the discharge nozzle is held up at a certain distance from its first section. Therefore the whole gaseous refrigerant coming out of the nozzle is directed towards the most intensively cooled first section of the foundry product. EFFECT: prevented formation of crystallized sections for improvement of the blank quality and focused cooling of the selected sections containing a great amount of heat. 20 cl, 23 dwg

Granted: 2003-06-27
Abstract: FIELD: hydraulic engineering; measurement technology. SUBSTANCE: proposed method consists in stream-flow-measuring in hydraulic systems. Method is based on use of ultrasonic oscillations and processing of results. Electroacoustic transducers are moved by means of movable carriage along vertical coordinate of water passage section. Said transducers are engageable by opposite sides of water conduit. Rate of motion is so selected that displacement of carriage is less than geometric sizes of electroacoustic transducers during time of propagation of ultrasonic waves between wall of water conduit. Movable carriage is moved continuously at constant velocity at simultaneous obtaining of integral magnitude of stream velocity along horizontal coordinates of water conduit area by means of ultrasonic meter. In the course of scanning of water conduit for reliability of results of measurements, undistorted data are summed up and number of summed-up results of measurements are calculated. Upon completion of scanning, total magnitude of results of measurements is divided by total number of measurements for determination of average velocity of stream and results thus obtained is multiplied by water conduit area for determination of water flow rate:   where Q is flow rate of water in water conduit; S is area of water conduit; X is size of water conduit along coordinate x; N y  is number of measurements made during scanning of water conduit along coordinate y; v x  is component of stream velocity vector along coordinate x normal to plane of water conduit section.
