Abstract: The socket wrench extension has an insertion member with a polygonal socket head having a lateral socket head surface. A receiving member with a polygonal socket is provided and a tube rigidly connects the insertion member and the receiving member.          The locking member is moveably connected within the insertion member such that the locking element partially projects from the lateral socket head surface. The pressure transmission member is axially moveable in the tube. The pressure transmission member has a first and a second end. The first end serves as an actuation member for the pressure transmission member. The second end transforms the axial movement of the pressure transmission member, directed toward the insertion member, into an outward movement of the locking member. The receiving member has an axial bore and a guide sleeve which is inserted into the axial bore of the receiving member for guiding the first end of the pressure transmission member. The guide sleeve has an insertion diameter (press-fit diameter) that is greater than the maximum diameter of the pressure transmission member.

Title: Meteorological radar system
Inventor: TANAKA HISAMICHI
IPC: G01W1/00
Filed: 1998-11-10
Abstract: A meteorological radar system that can continuously and detailedly observe an object. The search radar section continuously searches for an atmospheric phenomenon as a target within a wide search range while the search radar control section rotatably scans the search radar antenna. The scanning range deciding section decides the scanning range of an observation radar section from the location of an atmospheric phenomenon detected by the atmospheric phenomena detecting section with the data obtained by the search radar section and thus sets the observation radar control section in the observation radar section to the scanning range. The observation radar antenna can continuously observe a narrow scanning area corresponding to an object with narrowed beams while the search radar section continues its searching operation, so that an object can be measured with high space and time resolution.
Patent CA-2256087-A1 (CA)
Inventor: SCHELP CARSTEN
IPC: G01N33/554
Filed: 1998-12-15
Abstract: The present invention relates to procedures for the detection or for the determination of solid phase-associated factors, which are multiply associated with the same solid phase. According to the invention, the sample is brought into contact with a transmitter particle, on which at least one ligand having binding affinity for a solid phase-associated factor and a transmitter are immobilized, and a receiver particle, on which at least one ligand having binding affinity for said solid phase- associated factor and a receiver is immobilized, and then the signal is determined which results when transmitter and receiver are brought sufficiently close to one another. In particular, the invention relates to the detection of cell surface receptors which can be used for the typing of cells or for the determination of cell activation states. It is thus possible to replace the hitherto widely customary flow cytometry by a more simple procedure.

Patent CA-2280222-A1 (CA)
Title: Roof curb apparatus
Inventor: BROWN PHILLIP G
IPC: E04D13/03
Filed: 1999-08-13
Abstract: The four metal panel portions of an air conditioning unit roof curb have spaced sets of inwardly projecting lanced portions positioned adjacent their ends and defining tab-receiving slots. With the panel portions in a rectangular assembly orientation, specially designed drive cleats are used to lock the contiguous ends of the panel portions together at the corners of the curb. Each cleat has spaced pairs of tabs which, when the cleat is downwardly driven into place on a corner section of the curb, sequentially enter vertically successive pairs of slots in the contiguous panel end portions at the corner. In this manner, only one tab pair and one slot pair need to be aligned with one another before the cleat is driven into place to lock the two contiguous panel end portions to one another, the initial tab pair/slot pair alignment serving to automatically align the successive tab and slot pairs as the cleat is driven home. A pair of the tabs on each drive cleat have dimples thereon which function as detent structures that releasably lock the cleat tabs in their panel slots and thereby releasably retain the drive cleat in place on the assembled roof curb. In an alternate embodiment of the drive cleats, side halves thereof are formed integrally with ends of the panel portions, with the tabs of the integrally formed cleat halves being sequentially insertable into the tab-receiving lance slots of adjacent panel end portions.

Abstract: A method of treating wood chips allows chemical pulp (e. g. kraft pulp) to be produced having enhanced fiber strength properties. In a first zone or stage the chips are cool impregnated (e. g. a temperature of about 60-120°C) with a first alkali-containing liquid (25-35 g/l expressed as NaOH). In the top of a continuous digester in a second zone or stage the chips are then treated with a second alkali-containing liquid having an alkali concentration at least 5 g/l less than the first liquid (e.g. 10-20 g/l) and a temperature of between about 120-160°C (e.g. 130-150°C).  An extraction typically takes place to effect the change in treatment zones.  After the second zone the chips are cooked at about 140-180°C (e. g. 150-170°C), and higher than in the second zone.
