Abstract: A continuous mixing reactor has an outer shell having a cylindrical portion with a central section and two opposite conical end sections; a circulation tube within the shell so that an annular passage forms between the shell and the circulation tube; an impeller within and positioned adjacent to one end of the circulation tube; and heat exchange means penetrating the outer shell and extending into the end of the circulation tube opposite the impeller. The outer shell has a hydraulic head forming one end of the shell, a heat exchange medium header at the opposite end of the shell. The circulation tube nearer the heat exchange medium header terminates at or downstream from a tangential plane extending through the shell at the intersection of the central section and the conical end section of the cylindrical portion of shell. The reactor is useful in an alkylation process.

Abstract: A device for pulling and or twisting a release arm on a side of a fifth wheel of a tractor to release the tractor from the trailer has an elongated hollow body member. A hook member is attached to a bottom section of the elongated hollow body member. A rod member is positioned within the elongated hollow body n ember, wherein the rod member moved up and down within the elongated hollow body member. A locking mechanism is used to lock the rod member in a retracted position within the elongated hollow body member and in an extended position within the elongated hollow body ember.

Abstract: A telecommunications device and a method for providing information to a party placed on hold during a call waiting condition. The telecommunications device includes a memory unit, and a call waiting module in communication with the memory unit. The call waiting module is for transmitting information stored in the memory unit to the party when the call waiting condition is detected.

Abstract: Disclosed are isolated nucleic acids consisting essentially of RPW nucleotide sequences (especially RPW8 from Arabidopsis thaliana, and related homologues and other sequences e.g. from Brassica napus; B. oleracea). These encode a novel class of resistance polypeptides having an N-terminal transmembrane domain and a coiled coil domain and which is capable of recognising and activating in a plant into which said nucleic acid is introduced a specific defense response to challenge with a powdery mildew pathogen e.g. E. cichoracearum. Also provided are related products e.g. primers, polypeptides, transgenic plants having enhanced resistance, plus also processes for producing these, and methods of use.

Abstract: The Medic-Cam is a wireless, highly integrated, portable, lightweight sys which provides high quality video and audio communications between highly trained specialists and remotely located field personnel. The system utilizes a head mounted display, a subminiature high resolution color CCD camera, microphone, transmitter, receiver, antenna, battery and vest. The size and integration of the head mounted components allow it to be worn under a combat kevlar helmet.
