Title: Method of manufacturing cast blank of wear-resistant cast iron for quick-wearable parts
Inventor: KUL BOVSKIJ I K
IPC: C21C1/08
Filed: 1996-01-23
Granted: 1998-06-20
Abstract: FIELD: ferrous metallurgy. SUBSTANCE: smelting of cast iron is performed by fusing iron-carbon charge in electrical furnace while simultaneously alloying charge for specified composition. Modification is carried out using silica-barium when smelt heated in the furnace to 1400-1470 C is tapped into ladle. Smelted cast iron is composed of (in wt %): C, 2.4-4.0; Si, 0.5-1.5; Mn, 2.0-4.0; Ni, 2.0- 4.0; Cr, 8.0-12.0; molybdenum, 0.5-0.8; B, 0.1-0.3; Ba, 0.005-0.001; P, 0.02-0.01; S, 0.02-0.07; Fe, the balance. Castings are obtained by filling sand or metal mold with specified-composition cast iron melt. Castings are then cleaned, cut, and thermally treated. The latter procedure is performed as high-temperature tempering including heating to 690-710 C, maintaining this temperature for 6-7 h, and cooling first in furnace to 400 C and then in air. Metal blanks are used, for example, for replaceable parts of mineral processing equipment, grinding bodies of ball mills. EFFECT: increased strength and wear-resistance of castings and reduced their cost.

Title: Method of attraction and transfer of fish from lower pool of hydraulic works into upper pool
Inventor: VVEDENSKIJ O G
IPC: E02B8/08
Filed: 1998-04-21
Granted: 1999-05-27
Abstract: FIELD: hydraulic engineering. SUBSTANCE: proposed method comes to creating controlled water flow depending on difference in levels of upper and lower pools and type of fish. Rectangular fishway (swim-in) hole is made in upper wall separating upper pool lower one and jet forming nozzles are installed over perimeter of hole at angle to hole axis. Water flowing through these nozzles forms two rows of parallel drowned hydraulic napes pointed towards upper pool from fishway hole with initial velocity V 0 . Relative interaction of napes takes place at a certain distance X 1  from fishway hole, thus forming summary flow. At further propagation of summary flow, axial velocity is reduced due to pulsation velocities (flow area F is increased) and counterflow velocity which depends on difference in water levels in upper and lower pools. At a certain distance X 2  axial velocity V x  of summary flow propagation tends to 0, and flow in this direction fades. Thus, zone of partial equal pressures is formed: pressure (hydraulic stop) of summary flow at a distance X 2  from vertical wall, and pressure built by water column (head) H from side of upper pool. Barrier wall can be used to decrease ejection of summary flow. By changing initial conditions of nappe flowage velocity V of controlled water flow attracting the fish can be changed to suit type of moving fish. Zone of partially equal pressures provides unobstructed passage of fish from lower pool of hydraulic works into upper pool and back. EFFECT: provision of safe passage of fish. 1 dwg

Title: Device for restriction of door opening
Inventor: GOLUBEV V I
IPC: E05C17/02
Filed: 1999-06-04
Granted: 2000-05-27
Abstract: FIELD: civil engineering. SUBSTANCE: device is used as door safety devices for protection of various objects from unauthorized access to them, particularly, locking devices of dwellings. The device has tight coupling in the form of bell-crank whose one end carriers latch engageable with guide secured to door immovable member - door jamb or wall. Secured to other end of bell-crank is pivot movable beyond door wing and engageable with jamb. Bell-crank is secured by hinge which allows its turning and limited linear motions relative to door wing. Bell-crank is spring-loaded relative to door wing by means of flexible member and engageable with drive mechanism through link. Drive mechanism may be provided with extensible cross-bar locking the latch in its closed position. With closed door wing, flexible member acting on bell-crank presses the pivot to door jamb, and latch to guide. Cross-bar advanced out of drive mechanism enters clearance between guide and latch to interlock the latter from linear motions along guide and bell-crank from turning in hinge. Under conditions of door opening with restriction, drive mechanism withdraws cross-bar releasing the latch which is pressed to guide by flexible member. Door opening results in latch entering the guide and its moving in it up to extreme position. At the same time, pivot comes off the jamb. In this case, moment developed by flexible member is counterbalanced by moment developed by link forces on bell-crank and guide on latch. Change of angular position of bell-crank caused by opening of door wing is corrected due to flexible member and possibility of linear and angular displacement of bell-crank in hinge. In case of unauthorized opening the door wing, when device is in state of opening with restriction, load from door wing is transmitted through hinge, bell-crank, latch and guide are taken up by fastening units of the latter on jamb. EFFECT: increased convenience of device using and provision for additional protection of rooms. 2 cl, 1 dwg
