Title: Final rinse process for automatic dishwashing machine
Inventor: HAAKANSON HAAKAN
IPC: A47L/
Filed: 1998-03-04
Abstract: Once the desired rinse volume is set the final rinse step is initiated by opening the closure valve to allow cold water to enter the bottom end of the flow-through tank under pressure, and at the same time hot water is removed from the top end of the tank. Water flow or pressure in the cold water inlet for the tank is measured at a position downstream from the closure valve. The volume of water flowing through the tank is calculated on the basis of the water flow or pressure and the dimensions of the cold water inlet and the rinse tank. Once the volume of water flowing through the tank corresponds to the pre-selected rinse volume, the valve is closed in order to cut off the supply of hot water from the top end of the tank.

Title: Method of mine workings ventilation
Inventor: ATRUSHKEVICH A A
IPC: E21F1/00
Filed: 1997-06-17
Granted: 2001-04-27
Abstract: FIELD: mining industry, particularly, coal industry for ventilation of mine development workings and breakage faces. SUBSTANCE: method is characterized by the fact that atmospheric air with subzero temperature is supplied to network of heat-exchange workings with increased surface of heat exchange due to utilization of depth processes of geothermal transfer. Geothermal is retained in rocks surrounding mine working. Heat conduction of rocks is increased by injection of water at initial period of winter season into rocks surrounding the heat-exchange workings. Efficiency of heat-transfer process is increased due to installation of heat conducting anchors over perimeter of heat-exchanger workings. Air is moved to network of crosscut coal boreholes where air is additionally heated due to heat exchange and coal oxidation until it attains positive temperature and supplied to active workings. Anchors are of variable length. Installed in entrance zone of heat-exchange workings are anchors with length no less of average radius of workings, and length of other anchors are equal to at least 2-5 radii of working. EFFECT: considerable reduction of expenses for ventilation due to abandoning of artificial heating of air supplied to mines during winter season. 3 cl, 2 dwg

Title: Flexible sprinkler sweep and operating method
Inventor: BLAGOVESTNYJ L S
IPC: A01G25/09
Filed: 1998-09-14
Granted: 2001-05-27
Abstract: FIELD: agriculture. SUBSTANCE: flexible sprinkler has flexible main pipeline, U-shaped stabilizers with drive supports (wheel or skid), risers with sprinkler units, hydraulic fittings, pulling equipment, and rotary supports employed in conjunction with sweep. Operating method involves moving sweep to parallel tracks in transverse direction by means of supports made in the form of arc parts with radius equal to admissible radius of curvature of pulled main pipeline-sweep; reducing friction resistance by equipping arcs with rollers or facing them with antifriction material. Rotary supports are positioned at ends of longitudinal tracks and sweep does not intersect plant rows to reduce losses of useful area and prevent plants from being damaged during movement of sweep. Sweep is moved in loop-shaped progressive motions along field surface, with transverse motions being performed along field boundaries. Method allows irrigation of all sweep positions in equal time intervals to be performed simultaneously, since sweep may be transferred from terminating position to initial position by effecting single transverse motion. Moreover, reciprocating motion detrimental to main pipeline is eliminated, for turns at loop-shaped motions are effected on one and the same side. Rotary supports may be left at the site for the entire irrigation season because they do not hinder young crop caring works. EFFECT: increased efficiency, wider operational capabilities and reduced damage to plants. 6 cl, 3 dwg
