Abstract: Coolant pump service in a crowded engine compartment is provided by forming the side wall of the pump drive pulley with a centralized and radially lobed opening which can accommodate the radial arms of the drive hub that are normally connected by screws to the pulley side wall. The drive hub is fixed to the outboard end of the coolant pump drive shaft that extends through the housing of the pump that is removably secured by screws to the block of an internal combustion engine. The pump impeller is mounted on the inboard end of the drive shaft for fluid pumping operation in a coolant-receiving cavity in the coolant circuit of the engine. In the event of interference, which prevents or hampers the removal of the pulley axially from the drive shaft, the hub screws are removed and the pulley is turned into alignment with the lobes of the opening so that the pump housing screws are accessible. These screws are then removed so that the pump can be manually removed from the clearance between the engine and the frame side rail or other interfering component. <IMAGE>

Abstract: An access point (GGSN) from a mobile communications system to an external system is selected (3) at a service node (SGSN) of the mobile communications system based on at least two or three grounds of selection: the subscription data of a mobile subscriber stored in the mobile communication system or an access point selection data given by a user in a service request (1), or on other grounds. The serving node sends to the access point (GGSN) selected a further service request (4) which includes indication of the grounds of the selection, i.e. whether the access point is selected by subscription, by a user, or based on any other grounds. Thereby the access point is able to distinguish and accept service requests in which the rights of the user are already assured by the subscription, without any security problems. When the request is based on the selection of the access point by the user, or on any other insecure grounds, the access point is able to make any further actions to ensure the security. These further actions may include rejection of the service request.

Abstract: The present invention relates to a novel method for the selection of clones of an expression library. The method is characterized by the step of analyzing for the expression of at least one (poly)peptide, such as a tag expressed in frame with a recombinant insert of said expression library, wherein said clones of said expression library are arranged in arrayed form. Screening for the expression of said (poly)peptide allows for the rearraying of clones that express the recombinant insert. Upon rearraying said clones, the library will now comprise clones having inserts in the correct reading frame to a very high degree. Optionally, the library is additionally screened for desired inserts either by contacting the expressed library with a ligand specific for the expression product or by hybridizing or fingerprinting the inserts with a nucleic acid probe.

Abstract: A variable spot size x-ray tube comprises a cathode having an electron emitting surface providing an electron beam that travels essentially along the tube axis of symmetry to an anode. The anode, spaced from the cathode, includes a target, the front surface of which is disposed at an oblique angle with respect to the axis of symmetry. The potential of the anode is generally positive with respect to that of the cathode. The cathode is heated to a temperature at which electrons are emitted by the thermionic emission process. Current from the cathode can be controlled by varying the cathode temperature if the cathode is operated in the temperature limited region. The incident electron beam forms a spot on the target surface whereupon x-rays are produced in response to impingement of the electron beam on the target. The x-rays propagate outwardly from the target spot through a vacuum window to form a beam of x-radiation outside the x-ray tube. An aperture grid is disposed between the cathode and the anode, and has a central aperture permitting the electron beam to pass therethrough. The aperture grid further has a variable voltage applied to it which may be positive, negative, or equal to the potential of the cathode. The voltage on the control grid is used to control the diameter of the electron beam which impinges upon the target. Specifically, the electron beam diameter varies in correspondence with the variable aperture grid voltage, and selective variation of the electron beam diameter results in a corresponding variation in size of the x-ray imaging spot.
