Title: Modulated bias unit for rotary drilling
Inventor: THORP RICHARD EDWARD
IPC: E21B7/08
Filed: 1995-06-01
Abstract: A modulated bias unit, for controlling the direction of drilling of a rotary drill bit when drilling boreholes in subsurface formations, comprises a number of hydraulic actuators spaced apart around the periphery of the unit. Each actuator comprises a movable thrust member which is hydraulically displaceable outwardly and a pivotally mounted formation-engaging pad which overlies the thrust member. An inlet passage supplies fluid under pressure to the chamber, and an outlet passage delivers fluid from the chamber to a lower pressure zone. A selector control valve modulates the fluid pressure supplied to each actuator in synchronism with rotation of the drill bit so that, as the drill bit rotates, each pad is displaced outwardly at the same selected rotational position so as to bias the drill bit laterally and thus control the direction of drilling. The outlet passage from the chamber passes through the thrust member so as to wash the region where the formation-engaging pad overlies the thrust member as the fluid flows to the annulus between the unit and the borehole.

Title: Port system for sterile transfer
Inventor: HAAG EARL C III
IPC: B65G49/00
Filed: 1995-10-27
Abstract: A port system for allowing transfer of material between sterile environments in two walled enclosures includes film members attached to each of the enclosures and covering ports through the walls of the enclosures.  The exterior surfaces of the film members are coated with adhesives of a type which will cause the film members to adhere when brought into contact with each other.  To transfer material, the enclosures are brought together with film covered ports in alignment, and upon contact the adhesive covered surfaces cause the film members to adhere.  The film members are constructed and arranged so that the portions covering the ports in the walls of the enclosures can be separated from the portions surrounding the ports. After adherence, the separable portions are removed, enabling transfer to occur through the now open ports.          Since the adhesive surfaces of the film members are the only surfaces exposed to the outside atmosphere, when they are brought together in adhering relationship, each effectively covers the exposed surface of the other, thereby preventing contamination of the sterile environments maintained in the enclosures.

Title: Circuit arrangement for accepting and forwarding message cells with an atm communication equipment
Inventor: RIEDEL MICHAEL
IPC: H04L49/111
Filed: 1996-03-01
Abstract: The ATM communication equipment (KE) serves the purpose of forwarding message cells supplied via at least one offering trunk (E1,...,En) during to course of virtual connections to a serving trunk arrangement (A1,...,An) coming into consideration for the respective virtual connection. Characteristic parameters as well as at least two different priorities are thereby defined for the respective virtual connection during the course of the call set up. The respective serving trunk arrangement has a handling means (BHE) allocated to it that has a central cell memory (CM) in which call-associated cell waiting lists are established for storing message cells. A control means (STE) in which an allocation table (LUT) is kept is connected to the cell memory. This allocation table allocates a waiting list identifier as well as a priority identifier to the call information (VPA/VCI) carried in the message cells. Based on the criterion of the individual priority identifiers, the appertaining waiting list identifiers are inserted into a reference waiting list (Q1 ,Q2) allocated to the respective priority. These reference waiting list are processed with different priorities, whereby the waiting list identifiers thereby offered are successively supplied to the cell memory (CM) for an output of stored message cells.
