Abstract: Eine Kupplung zwischen einem Werkzeugkopf (2) und einem Werkzeugträger (1) weist zur Grobpositionierung eine Aufnahme-Zapfen-Verbindung auf. Mittels zumindest eines in Axialrichtung des Werkzeugträgers (1) verlaufenden Befestigungsbolzens (10) wird der Werkzeugkopf (2) mit dem Werkzeugträger (1) verspannt. Dabei tritt der Befestigungsbolzen (10) über eine erste Gewindeverbindung (10a) mit dem Werkzeugkopf (2) und über eine zweite Gewindeverbindung (10b) mit dem Werkzeugträger (1) in Eingriff, wobei die erste und die zweite Gewindeverbindung gleichgängige Gewinde unterschiedlicher Steigung aufweisen, so daß bei Anziehen des Befestigungsbolzens (10) der Werkzeugträger (1) und der Werkzeugkopf (2) in Axialrichtung miteinander verspannt werden. Des weiteren weist der Befestigungsbolzen (10) einen Zentrierabschnitt (10c) auf, der im zusammengebauten Zustand der Kupplung den Werkzeugkopf (2) bezüglich des Werkzeuträgers (1) zentriert. Der Befestigungsbolzen (10) ist im zusammengebauten Zustand der Kupplung in seiner Gesamtheit im Inneren der aus Werkzeugträger (1) und Werkzeugkopf (2) gebildeten Einheit aufgenommen und nur über eine Bohrung (5) zugänglich. Vorteilhafterweise dient diese Bohrung (5) auch also Kühlkanalbohrung, so daß sie bei Gebrauch von einem Kühlmittel durchströmt ist, wodurch das Eindringen von Verunreinigungen in die Kupplung ausgeschlossen ist.

Abstract: Discolsed is a process of preparing a single-stranded DNA. In the first step of the process of the present invention, a single-stranded DNA containing a template DNA region is provided. Then a terminating structure which terminates the extension of DNA chain which is to be formed using the template DNA as a template in a later step is introduced at the 5ʹ end portion of the template DNA. Then one or more primers are hybridized with one or more portion of the template DNA. Therafter, the primer is extended utilizing the template DNA as a template. Finally, the single-stranded DNA formed by the extension of the primer is separated and recovered.

Abstract: An aircraft flight control system for use with a dual or tandem hydraulic actuator coupled to a flight control surface through an actuating rod. Each half of the tandem actuator is controlled by a respective electrohydraulic servo­valve. Each electrohydraulic servovalve is controlled by signals applied to either of two actuating coils. Control signals are applied to the actuating coils from three control­lers. The control signals are generated as a function of the difference between the flight control signal and a feedback signal indicative of the position of the actuating rod. Each electrohydraulic servovalve includes a pair of linear variable differential transformers generating feedback signals indica­tive of the position of the valve stem in each electrohydraulic servovalve. The valve feedback signals are compared to each other and to reference signals corresponding to the expected value of such feedback signals in order to detect and identify malfunctions in the flight control system. In one embodiment, the electrohydraulic servovalves are controlled by two channels of a primary controller in normal operation. In the event of a malfunction, control is transferred to one of two secondary controllers. In another embodiment, the electrohydraulic servo­valves are controlled by respective primary controllers, with control being transferred to one of two channels of a secondary controller in the event of a malfunction.

Abstract: This invention relates to a novel method for the delivery of cytotoxic drugs to tumor cells by the administration of a tumor-specific antibody-enzyme conjugate that binds to the tumor cells, and the additional administration of a prodrug that is converted at the tumor site, in the presence of the antibody-bound enzyme, to an active cytotoxic drug. According to preferred embodiments of this invention, antibody-enzyme conjugates containing the enzyme, alkaline phosphatase ("AP"), have been used in conjunction with the novel prodrug, etoposide-4′-phosphate or 7-(2′-aminoethyl phosphate)mitomycin or a combination thereof, to effect killing of tumor cells. According to another embodiment of the invention, an antibody-enzyme conjugate containing the enzyme, penicillin V amidase ("PVA"), has been used. in conjunction with a novel prodrug, N-( p -hydroxyphenoxyacetyl)adriamycin to effect killing of tumor cells. Still another embodiment of the invention relates to the use of an antibody-enzyme conjugate containing the enzyme, cytosine deaminase ("CD"), in combination with the prodrug, 5-fluorocytosine, to effect killing of tumor cells. The methods, antibody-enzyme conjugates, prodrugs, pharmaceutical compositions and combinations of this invention provide for enhanced selective killing of tumor cells and are thus useful in the treatment of cancers and other tumors.

Abstract: An apparatus for liquefying a highly polymeric thermoplastic material, in particular a hot-melt adhesive, in a transport container has a mount for the transport container, the extraction opening of which is directed downwards, a heating means for heating and thereby liquefying the material in the region of the extraction opening of the transport container as well as a conveying means, arranged underneath the transport container, for the material running out. In order to ensure continuous operation, even when the transport container is being changed, either a collecting container of variable volume is arranged underneath the transport container, which receives the material running out and passes it on to the conveying means, or at least two transport containers are provided parallel to one another, the flow of highly polymeric material being taken during normal operation in a proportion between them of at least 2:1. If a collecting container is used, it serves as a buffer volume, so that when the transport container is being changed the conveying means is fed from the collecting container. If two transport containers are used, the emptied transport container is switched off, so that while it is being changed the entire flow of material is taken from the other transport container. <IMAGE>

Abstract: By combining a pad having a repositionable adhesive with a carbonless imaging system, multiple copies of a writing on the top sheet of the pad are provided. These features have application in pads for memos, interoffice correspondence, and notes. A user may select the desired set of copies by removing the required number of sheets from the pad. If a divider is provided with each pad, e.g. a cardboard or a hard insert sheet, the multiple pages are imaged before they are removed from the pad by inserting the divider into the pad after counting the appropriate number of sheets to be copied. Thus, the divider prevents copying and imaging throughout the entire pad.

Abstract: The state of inflation of inflatable tyres of a vehicle is monitored by providing a transducer output dependent on the load experienced by each wheel, by generating from the outputs a signal representing the instantaneous value of the warp load of the vehicle, and producing an output representing the rate of change of the average warp load. This output is compared with a reference signal representing a predetermined rate of change of average warp load, to energize indicating means when the output exceeds the reference signal. The indicating means can indicate a deflation condition to the driver of the vehicle and/or to the driver of a following vehicle. Vehicle speed can be limited in response to a detected deflation condition.
