Abstract: According to the method of the invention, the final power value which occurs at the end of the mixing process is forecast during the mixing process as early as the water inflow phase with a discrete Kalman filter, using a relationship between the mean power value of the mixing motor, which correlates with the consistency, and the quantity of water currently admixed. This forecast final power value is compared to a desired final power value, which is fixed as a device and formulation parameter, and the difference is used to determine the residual quantity of water required and hence for controlling the water valve. The circuitry consists essentially of an active-power measuring device (13), which is connected via a time-controlled electronic change-over switch (14) to a first-order Kalman filter (15) or via measuring-transducer units (16, 17) to a third-order Kalman filter (20) and a circuit (23) for determining the final value. The signal present at the output of the circuit (23) for determining the final value, which signal characterises the consistency, is compared to a device and formulation parameter, fixed in a read-only memory, (25) by means of a differential amplifier (24). An evaluation circuit (27) uses the difference to derive the water-valve control times of the mixing installation (5).

Abstract: A variable beamwidth stage light relying upon an axially movable reflector for changes in beamwidth. The reflector has a plurality of radially outwardly and axially forwardly extending leaves in side-by-side relation to define a bowl-shaped reflector surface. A stationary support flange is in frictional contact with the radially outward surface of each leaf. The reflector leaves are sandwiched between a base member and a ring member at the base of the reflector. A motor driven lead screw is attached to the base member to cause axial movement of the reflector relative to the support flange. The reflector defines a first and a second focal point along the axis of the reflector. A light source is fixed at the first focal point, which remains substantially fixed relative to the base member. Contact of the support flange with the reflector leaves causes the diameter of the reflector leaves to vary as the base member is moved, thereby causing displacement of the second focal point and variation of the bandwidth issuing from the reflector.

Abstract: The invention relates to a cement for the cathode blocks of electrolytic cells, e.g. Hall-Heroult cells used for the production of aluminum. The cement comprises a carbonaceous aggregate of particle size smaller than 48 Tyler mesh, a curable water-soluble liquid polymeric resin (preferably a phenol-formaldehyde resin), water and normally a curing agent for the resin. The water is used in such an amount that the proportion of the resin can be reduced without adversely affecting the viscosity of the cement at ambient temperature. The cement carbonizes when the cell is used and has a linear shrinkage of less than 5%, which reduces the tendency of the carbonized cement to crack during operation of the cell.
