Abstract: A plug-in coupling for connecting a fluid line with a pipe having a circumferential holding rib includes a pipe piece with a first end portion connectable to the fluid line and a second end portion which can be plugged together with the pipe, wherein the second end portion is connectable to a first coupling ring part of a coupling ring and is connected through elastic holding arms to a non-circular elastically expandable second coupling ring part. The second coupling ring part has locking sections which are distributed over a predetermined circumferential angle range of a circumference of the pipe piece. When the pipe and pipe piece are plugged together, the locking sections slide over the holding rib and expand the second coupling ring part and engage behind the holding rib, wherein the components located between the locking sections of the second coupling ring part are arched outwardly.

Abstract: A plug-in coupling for connecting a fluid conduit to a pipe has a pipe section having a first end section to be connected to a fluid-conduit and a second end section to receive and lock a pipe. A securing ring is attached to the inner side of the pipe section. At least one sealing ring is inserted into the pipe section and seals the pipe relative to the pipe section. The at least one sealing ring is positionally secured in the pipe section between the securing ring and an inner shoulder of the pipe section. The pipe section has a slot extending in a circumferential direction of the pipe section and a support surface located opposite the slot. The securing ring is inserted into the slot until the securing ring contacts the support surface. A circumferential section of the securing ring is received in the slot.

Abstract: Primary aminoalkyl-terminated organopolysiloxanes are prepared simply and in high yield by reaction of hydroxyl-terminated organopolysiloxanes with an aminoalkyl-and alkoxy-functional silane. The primary aminoalkyl-terminated organopolysiloxanes are particularly useful as polymer intermediates in the preparation of polymers such as polyimides and polyureas.

Abstract: A heating device includes an electrical heat source for heating a fluid in a fluid line of a motor vehicle, and a heat conducting device which is in connection with the heat source. The heat conducting device is connected with a hose clamp for connecting the heat conducting device to the fluid line. The heat conducting device may include a metal strip, the one end of which is in contact with the heat source and the other end is connected to the clamp. This metal strip facilitates the heat transfer from the heat source through the clamp to the fluid line.

Abstract: A continuous process for preparing alkylamines comprises reacting continuous streams of ammonia and alkyl halide in a molar ratio of at least 10:1 in a pressure reactor. The ultimate reaction mixture has a temperature of >80° C., a pressure of >40 bar and an ammonium halide content of >1% by weight, and comprises two phases (A) a first phase comprising at least 75% by weight of the total amount of ammonium halide formed, and (B) a second phase comprising at least 80% by weight of the total amount of alkylamine formed. The first and second phases are separated, and an alkylamine product is recovered therefrom.

Abstract: Alkoxy-crosslinking one-component moisture curing compositions contain a polymer bearing (alkoxy)(methyl)silylalkyl-terminal groups, and specific silanes as described herein. The compositions exhibit improved shelf life and yet retain other desirable characteristics.

Abstract: A polyurethane binder with a low content of readily volatile isocyanate-functional monomer is provided by a process of (a) reacting a first at least difunctional isocyanate and a first polyol component at an NCO:OH ratio less than 2 wherein the first at least difunctional isocyanate has an NCO group with a slower rate of reaction with the OH groups than a second NCO group to produce a reaction product containing free OH groups and reacting the reaction product with a second polyol and a second at least difunctional isocyanate wherein the second at least difunctional isocyanate has isocyanate groups with a more rapid rate of reaction with the OH groups than the predominent percentage of isocyanate groups present in the reaction product.

Abstract: The present invention relates to novel components of the cleavage/polyadenylation machinery of precursor mRNA as well as to the complex containing the new components and its use. The complex is obtained by using one component thereof as a bait and isolating a highly organized complex consisting of at least 13 distinct proteins.

Abstract: An apparatus and method for implementing one or more existing object-oriented program classes as component objects in an object management system, each class including one or more member functions, each class being defined in a header file, builds an information list, the information list including a list of the classes and the member functions in each class, processes the information list, the processing including parsing the header file for each class and reading a type file, the type file including computer code for converting between an object-oriented type and an object management type, and generates from the processed information list one or more output files for each component object, each component object implementing the member functions of one class.

Abstract: There is disclosed a client-server configuration including a peripheral device wherein multiple servers interface with both the client and the peripheral. Management software for determining the operating state of the peripheral, known as server agent software, is employed in the multiple servers under control of the client. In order to avoid conflicting information reflecting multiple operating states of the peripheral, a primary/secondary algorithm is used to enable the client to determine only one peripheral operating state while allowing each server to also verify its connectivity to the peripheral and to the client.

Abstract: A coupling device has a coupling receptacle and a matching coupling insert received in the coupling receptacle for connecting two components conveying a fluid. The coupling receptacle has two lateral, diametrically opposed slots and a U-shaped, elastic securing bracket seated on the coupling receptacle with two legs projecting into the lateral slots. The coupling insert has an outer peripheral securing rib and the legs of the securing bracket snap into place behind the securing ring in the coupling position of the coupling device. A securing bushing is arranged inside the coupling receptacle and faces a sealing ring with one end while the other end rests radially outwardly on the securing rib and projects past the lateral slots. The securing bushing has two transverse slots aligned with the two lateral slots, and the two legs of the securing bracket engage the two transverse slots of the securing bushing.

Abstract: A method and apparatus for controlling a peripheral device is provided. In a server, in a client/server environment, a server application receives a request for execution of a peripheral device script from a client application. The server application retrieves a peripheral device script which is associated with the request and the peripheral device script is passed to a script interpreter. The script interpreter converts the peripheral device script into at least one control signal. A device control module is coupled to the script interpreter and sends the control signal to the peripheral device. The device control module receives information signals from the peripheral device and forwards the information signals to the client application. The script may include code for configuring the peripheral device, code for requesting information about the peripheral device or code for controlling the peripheral device.
