Title: Control process to determine the exactitude of tooling machines, and device to carry out the process
Inventor: KNAPP WOLFGANG
IPC: G01B7/00
Filed: 1983-09-17
Granted: 1989-09-14
Abstract: A system for determining the precision of a numerically controlled machine tool involves setting the machine tool control to define a circular path. A circular standard is then aligned with the machine tool to sense the desired circular path. A continuous or pointwise sensing, as a function of whether a path-controlled or a point-by-point-controlled machine is being measured, of the aligned standard is performed. A faulty machine tool does not accurately cover the defined circular path. Variations from the desired circle can be plotted and used for evaluation.

Title: Toxins and antibodies of c. difficile
Inventor: WILKINS TRACY DALE
IPC: C07K16/00
Filed: 1984-03-02
Granted: 1988-07-07
Abstract: Antibodies (Ab) specific for toxins of Clostridium difficile, opt. bound to a solid support, are new.  Esp. Ab are monospecific for either A or B toxin.  Also new are assays for toxigenic C. difficile using Ab. The immobilised Ab is incubated with the test sample to bind C. difficile antigens.  The bound antigen is then incubated with labelled, monospecific Ab, and the presence of label determined by detecting presence of the label.  Particularly, the label used is alkaline phosphatase.  In a modification, the monospecific Ab is not labelled, and detection is by reaction with a second, labelled antibody specific for the first. Alternatively, toxins are detected by agglutination of appropriately sensitised solid particles (or by inhibition of such agglutination).

Abstract: During the assembly of a gas circulation block, encased in sheet metal, a conical sheet-metal sleeve is placed onto a shaped block which is in the form of a truncated cone and made of a refractory material, then a sheet-metal cover provided with a gas supply tube is laid onto the larger end face of the shaped block and then the sheet-metal sleeve is welded onto the sheet-metal cover. In order to reduce the assembly effort and at the same time to create an improved gas circulation block, the conical sheet-metal sleeve is heated up before placing onto the shaped block and is then shrunk onto the shaped block. By the shrinking of the sleeve, every type of dimensional inaccuracy is compensated for, whether on the shaped block or on the sheet-metal sleeve, so that the sheet-metal sleeve, in the shrunk-on condition, sits uniformly and tightly against the shaped block over its entire periphery and its entire length.

Abstract: An arrangement for processing a speech message which uses arbitrary value codes to form time frame excitation signals. The arbitrary value codes, e.g., random numbers, are stored as well as signals indexing the codes and transform domain signals corresponding to the arbitrary codes are generated. The speech message is partitioned into time frame interval speech patterns and a first signal representative of the transform domain speech pattern of each successive time frame interval is formed responsive to the partitioned speech message. A plurality of second signals representative of time frame interval patterns corresponding to the transform code signals are generated responsive to said set of transform signals. One of the arbitrary code signals is selected jointly responsive to the first and second signals of each successive time interval to represent the time frame speech signal excitation, and the index signal corresponding to said selected arbitrary code signal is output. A replica of the speech message is formed from the arbitrary codes by concatenating a sequence of said arbitrary codes identified by the output index signals.

Abstract: The regulating valve has a heat responsive extension element which is prestressed and which extends crosswise of the gas line. The extension element biases the valve body into sealing engagement with the valve seat to maintain the valve in a normally closed position. Due to the slight deflection of the extension element, the thermal length variation of the extension element is transformed into an approximately 100-fold stroke of the valve body relative to the valve seat. The control accuracy of the valve is considerably increased.
