Abstract: The application disclosed a method and machine for the automatic setting of bricks onto a supporting layer. So far, prefabricated wall panels have been made by setting the bricks manually into a mold equipped with brick compartments and intended for the said panel. A separate mold had to be prepared for each different panel shape. The object of the present invention is to facilitate, speed up and decrease the cost of the setting of bricks. In the machine according to the invention, the method is carried out by feeding into a cassette conveyor (1, 2, 3, 4) a batch of filled cassettes, of which the first is directed to below the brick take-off device (5). When the cassette conveyor is full and the first cassette is under the take-off, the automatic operation of the machine is started. The brick take-off lifts the topmost brick layer from the cassette and lowers it onto a brick conveyor (6), wherefrom the brick rows are directed onto a transverse belt conveyor (8). A rotating wheel (9) has been fitted to receive one brick at a time into a compartment at its periphery and, after rotating half a round, to lower it onto a flight conveyor (10). The flight of the flight conveyor takes the brick fed by the turning device, or remains vacant if the rotating wheel has been programmed not to rotate and not to deliver a brick onto the flight. A full row of bricks is formed on the flight conveyor, and a pushing device (11) pushes the row onto a centering table (12), on which the distances between the bricks are evened out. A pick-up device above lifts the centered bricks, centering them in their longitudinal direction, and lowers them into the mold in one, two or several batches, in accordance with the desired bond, the machine moving forward one step between the lowerings in accordance with the programmed bond. The machine stops at the latest upon the panel being completed and also upon the cassettes having been emptied.

At least one of these coupling reactions is carried out in a completely or partly aqueous medium at pH 3-12, in the presence of a proteolytic enzyme capable of catalyzing the formation of a peptide which, if desired, is coupled with a reactive amino acid derivative or peptide derivative in the presence of the same or another proteolytic enzyme, further enzymatic or chemical coupling reactions being carried out, if necessary. The process, which is particularly suited for synthesizing the immunomodulating pentapeptides thymopentin and spleninopentin and their analogues, comprises several coupling strategies, the preferred enzymes for use in these strategies i.a. including thermolysin, trypsin, subtilisin, carboxypeptidase Y, elastase and bromelain. The process i.a. uses the intermediates Z1ABOR, Z1ABC(OR min )(OR sec ) and Z1ABC(OR)OH, wherein Z1 has the same meaning as R1, and R is alkyl or benzyl.

Abstract: An apparatus for metering, measuring, or dosing flowing media. A distribution slide valve is disposed in a housing between an inlet and an outlet. A metering piston is disposed in a chamber of the housing and divides the chamber into a first and a second metering chamber. The two end positions of the slide valve alternately connect the metering chambers to the inlet or outlet. Transfer passages are disposed on the periphery of the slide valve for selective connection of connecting passages to the inlet, the outlet, and the metering chambers. A transverse connection of the slide valve connects a central control channel thereof to the inlet via a first one of the transfer passages in either of the end positions of the slide valve. Each end of the latter is associated with a hydraulic control chamber into which the control channel opens. Relief passages connect the control chambers to the outlet. A piston rod connected to the metering piston extends axially displaceably through the larger diameter control channel, with the slide valve being axially movable relative to the piston rod. Sealing elements are disposed on the piston rod, with the control channel being adapted to be alternately sealed off relative to one or the other of the control chambers via these sealing elements.

Abstract: A polypeptide for production in yeast comprises a fusion of a signal peptide, a leader peptide and a heterologous protein or polypeptide. The polypeptide is modified in its amino acid sequence adjacent to a yeast processing site positioned between the C-terminal end of the leader peptide and the N-terminal end of the heterologous protein so as to provide a presentation of the processing site which makes it accessible to proteolytic cleavage. Such a presentation is provided by adding one or more amino acids (at least one of which is negatively charged) to either the C-terminal end of the leader or the N-terminal end of the protein, or both. The heterologous protein may, for instance, be aprotinin or insulin precursor or an analogue thereof.

Abstract: A multizone test device for the determination of analyte from a liquid test medium upon contact with the liquid test medium and a labeled reagent comprising a chemical group having a detectable chemical property. The test device preferably comprises multilayers including a reagent layer incorporated with an immobilized reagent and a detection layer incorporated with an immobilized form of an interactive detection reagent for the labeled reagent. The immobilized reagent and the labeled reagent comprise specific binding partners which will bind to each other dependent upon the amount of analyte present. Labeled reagent which does not become bound to the immobilized reagent in the reagent layer migrates into the detection layer and becomes bound to and immobilized by the immobilized binding substance therein. As a result, reverse migration of the labeled reagent into the reagent layer is prevented and the detectable physical property provided by the label of the labeled reagent is localized in the detection layer for the precise measurement thereof and correlation to the amount of analyte in the test medium.

Abstract: The present invention relates to branching directional couplers with a voltage and a current transformer and an internal terminating resistance, in which the junction of the secondary windings of the two transformers forms the branch and the internal terminating resistance is inserted between the secondary winding of the voltage transformer and earth. To achieve branch attenuations of >/= 16 dB in such a branching directional coupler, with little circuit complexity over a wide band up to 1.75 GHz with little transmission loss, a high degree of decoupling and good matching of all connections, an ohmic resistance connected in parallel with the secondary winding of the current transformer and connected to the latter with low inductance is provided which, together with the transformation ratios of the two transformers, is selected in such a manner that the nominal values for the branch attenuation and impedance are obtained as accurately as possible at the branch connection. By inserting a further ohmic resistance between the junction of the secondary windings of the two transformers and the branch connection, a further degree of freedom has been advantageously achieved for the choice of resistances and transformation ratios. <IMAGE>
