Abstract: A slip form paving machine includes a slip form mold having a mold width extending transversely to a paving direction. At least one smoothing beam is supported behind the slip form mold for engaging an upper surface of a formed not yet hardened concrete structure to smooth the upper surface, the at least one smoothing beam being configured to oscillate transversely to the paving direction. At least one advance speed sensor is configured to provide an advance speed signal corresponding to an advance speed of the slip form paving machine in the paving direction. A controller is configured to receive the advance speed signal and to generate a command signal to control a frequency of transverse oscillation of the at least one smoothing beam such that a constant relationship is maintained between the advance speed and the frequency of transverse oscillation.

Abstract: A slip form paving machine includes a machine frame (10), a plurality of ground engaging wheels or tracks (30,30F,30R) and front and rear height adjustable lifting columns (32,32F,32R) supporting the machine frame from the ground engaging wheels or tracks, the lifting columns being adjustable to adjust a longitudinal inclination of the machine frame in a paving direction (12). A slip form mold (24) is supported from the machine frame for molding a mass of concrete (16A) into a formed not yet hardened concrete slab as the paving machine moves forward in the paving direction. A swelling sensor (220) is arranged to detect a swelling of the formed not yet hardened concrete slab relative to the machine frame behind the slip form mold. A method of controlling the slip form paving machine is also disclosed.

Abstract: A slip form paving machine includes a machine frame, a plurality of ground engaging wheels or tracks, and front and rear height adjustable lifting columns, the lifting columns being adjustable to adjust a height of the machine frame relative to a ground surface. A slip form mold is supported from the machine frame. A front height sensor configured to detect a distance of the machine frame from the ground surface ahead of the concrete slab and generate a front height signal. A rear height sensor is configured to detect a distance of the machine frame from an upper surface of the concrete slab and generate a rear height signal. A controller is configured to receive the front and rear height signals and to determine a thickness of the concrete slab based at least in part on the front and rear height signals.

An oscillating beam is supported from the machine frame behind the slip form mold for engaging and oscillating transversely to the paving direction upon an upper surface of the formed not yet hardened concrete slab to smooth the upper surface. A roll size sensor is configured to detect a size of a roll of not yet hardened concrete created in front of the oscillating beam.

Abstract: A slip form paving machine includes a machine frame, a plurality of ground engaging wheels or tracks, and front and rear height adjustable lifting columns adjustable to adjust a longitudinal inclination of the machine frame in a paving direction. A slip form mold is supported from the machine frame. The machine further includes a front stringline sensor, a front sensor actuator arranged to adjust a vertical position of the front stringline sensor relative to the machine frame, a rear stringline sensor, and a rear sensor actuator arranged to adjust a vertical position of the rear stringline sensor relative to the machine frame. A controller is configured to send command signals to the front and rear sensor actuators to cause an adjustment in the longitudinal inclination of the machine frame.

Abstract: A baking process includes placing a baked goods carrier onto a work surface and filling the baked goods carrier with pieces of dough. Display data may be transmitted using a computer to a digitally controlled display apparatus close to the work surface for displaying a desired filling. The actual filling may be captured by an image recording apparatus and transmitted to the computer. The captured data of the actual filling may be evaluated using the computer and compared to data relating to the desired filling. The computer may be used to act on the filling process and/or the baking process.

Abstract: The present invention provides a method for identifying the presence of a protein inhibitor of a target protein in a sample, comprising the steps of a) contacting said sample with a cell, wherein said cell contains i) an inducible lethal overactivity mutation in a gene affecting the target protein; and ii) a mutation in a second gene, wherein the activity of the target protein is essential to the cell and the mutation in the second gene functionally compensates for any reduction in the activity of the target protein; b) inducing the lethal overactivity mutation; and subsequently c) assessing protein inhibition by comparing the degree of survival of the cell in the presence and the absence of said sample. Also provided are cells for use in said method.
