Abstract: The invention describes a method and its use for producing complex multienzymatical, storage resistant reaction mixtures for synthesizing, modifying or analyzing polypeptides and optionally nucleic acids characterized in that native or artificial enzymatical, active protein mixtures with reaction buffers, cofactors and substrates are prepared so that they are ready for use and are storage resistant such that only user-specific key components (e.g. mRNS) are missing to start the desired enzymatical reaction(s). In the method a stabilizer is added to the reaction mixtures in the solution which, on the one hand, increases the reacting capacity of the multienzymatical systems and, on the other hand, protects the unstable reaction components from losing their biological activity or their biologically active structure while being made storage resistant and during storage. The reaction mixture is made storage resistant by being easily freeze dried under a vacuum and then durably stored at 4-10° C.

Abstract: The present invention generally provides a running tool which can be released using hydraulic pressure and can provide continued rotation to a liner hanger or other tool disposed below and rotationally connected to the running tool. In one aspect, a hydraulic assembly is provided to release a thrusting cap from rotation so that a threaded connection between the running tool and the liner hanger can be released. On release of the liner hanger, a lock nut travels down a threaded surface of the thrusting cap and engages the thrusting cap to continue rotation through the thrusting cap. Additionally, the running tool may include a mechanical release operable without the assistance of hydraulic pressure.

The device includes a source region of the first conductivity type, a control region of a second conductivity type which is laterally spaced apart from the source region and a lateral drift region of the first conductivity type adjacent to the control region. A drain region of the first conductivity type is provided laterally spaced apart from the control region in a first lateral direction by the lateral drift region, and at least one field plate electrode is provided over at least a major portion of the lateral drift region and is insulated from the drift region by an insulation region.

Abstract: A method and system provide for selectively distributing communications between an application and multiple servers, allowing cooperative use of a single copy of an application. The system is situated between an application and the multiple servers. Requests from the application, responses to the requests, and events from the multiple servers, are managed in such a way that each server believes it is connected directly to the application and the application believes it is connected directly to a single server. The requests are categorized and distributed to the servers based on the type of request. The responses to these requests may be sent to the application or discarded based on the type of request and the role of the server sending the request. The events are also categorized and, based on the role of the server causing the event, they may be passed on to the application or discarded.

Abstract: A new overload protection device has been invented of the type in which components are fixed mutually by means of a safety member adapted to be cut or broken when the components are subjected to an overload, wherein the safety member is a thread spiral or spirals adapted to be cut loose from a member, rod or sleeve when the thread spiral (or spirals) is subjected to an overload.
