Title: Method and device for the weight-controlled filling of ingot molds in non-iron casting machines.
Inventor: WILLEMS ERICH
IPC: B22D37/00

Abstract: The invention relates to a method for the weight-accurate filling of ingot molds in a non-iron casting machine, e.g. a copper anode casting machine or a zinc anode casting machine, which is configured in the form of casting wheels that are use for production in a fully mechanized casting operation and are provided with the ingot molds. The aim of the invention is to obtain the desired precise-weight quality of a piece and exact plane parallelism of the bordering surfaces thereof. Said aim is achieved by carrying out the following steps: first, a liquid metal is introduced into an intermediate trough ( 4, 4 ') at a regulated mass flow rate, the continuous dynamic weight increase being simultaneously determined; second, liquid metal is fed into a dosing trough ( 4, 4 ') which is located on each side of the intermediate trough ( 4, 4 ') by alternately tilting the intermediate trough ( 4, 4 ') on one side followed by the other. After filling the first dosing trough ( 5 ), the intermediate trough ( 4 ) is tilted in the direction of the second dosing trough ( 5 ') while the mass of an anode is cast from the first filled dosing trough into one of the ingot molds ( 10, 10 ') that are arranged on the casting wheel ( 9, 9 ') by means of a controlled tilting movement. Also disclosed is a device for carrying out the inventive method.

Title: Method for filling and evacuating a dispenser unit and filling insert for dispenser unit.
Inventor: BERND NAUELS
IPC: B65B31/00
Filed: 2009-01-20
Abstract: The invention relates to a method for filling and evacuating a dispenser unit for pasty, foamy, or liquid media. In the known methods, a supply container (1) is evacuated via a suction pump (3), which is otherwise used to discharge the medium, after the filling. The danger exists in this way that medium will be sucked in. In order to make the suction process more effective and reliable, a method and a filling insert for a dispenser unit are proposed according to the invention, at least one air channel (2) being provided parallel to the suction pump (3). By applying a pressure differential between supply container (1) and surroundings, which is just high enough that air can be sucked through the air channel (2) but particularly no viscous medium, the evacuation is performed.

Title: Process for measuirng the dynamic viscosity in heavy crude oil from the oil well pressure to the atmospheric pressure, including the bubble poin pressure, based on an electromagnetic viscometer.
Inventor: SIMÓN LÓPEZ RAMÍREZ
IPC: G01N11/02
Filed: 2011-03-28
Abstract: The purpose of the present invention is to provide a process for experimentally determining reliable dynamic viscosities in heavy crude oil at a constant temperature (room temperature up to 463 K) and pressures of from about 68.9 MPA to about atmospheric pressure, including the dynamic viscosity in the bubble point pressure and under the same, based on a simple, reliable and accurate device. The device used in the present invention is based on an electromagnetic concept which only uses a mobile element (piston) through a fluid at a constant force. The time required by the piston to travel a fix distance is related in an exact manner to the dynamic viscosity of the fluid contained in a measurement chamber. When the fluid contained in the measurement chamber is more viscous, the displacement of the piston would be slower.
