Abstract: A system and a method of designing and mechanical packaging of pumped laser resonator elements to minimize their size. All the elements of the compact pumped laser resonator assembly (5) are placed on a monolithic block mount (10), which substitutes for and functions as a laser diode heatsink, a laser resonator cavity mount, and an optical bench. The laser optical cavity is in the form of a laser path (11) defined within the monolithic block mount (10), and includes a plurality of bends (40) in order to decrease the size of the assembly. The laser resonator optical elements include fold prisms (22, 24), a reflector (38), a retroreflector (32) and an intracavity optical Q-switch (30). The resultant miniaturized diode array pumped laser resonator assembly has a volume of less than one cubic inch and dimensions less than or equal to about 30 mm x 25 mm x 13 mm in metric units, and weighs less than two ounces or 56 g, while providing a laser power of more than 1 mJ. The compact pumped laser resonator is preferably manufactured by machining the monolithic block mount (10) using a computer-controlled machine, to generate a plurality of component mounts with a substantially identical setup and tolerances, in order to keep the laser resonator self-aligned.

Title: Device for detecting the position of a moveable magnet for generating a magnetic field
Inventor: SCHAEUBLE CAROLINE
IPC: G01B7/02
Filed: 1998-03-12
Granted: 2005-04-19
Abstract: The invention relates to a device for detecting the position of a magnet which is positioned so that it is moveable (3, 23, 24) to produce a magnetic field (6) through a ferromagnetic wall (1, 29), a magnetic field sensor (10, 21, 21') being situated in front of said wall.     When said magnet (3. 23, 24) is moved in relation to said wall (1), the lines (6) of the field build up a useful flux (6) which progresses in said wall (1, 29). Said useful flux has magnetic remanence (7) which is retained after the magnet (3, 23, 24) has passed by, is aligned along the movement axis of the magnet (3, 23, 24) in accordance with the polarity, and builds up a fringing flux (12) to the front side of the wall (1.29) where the magnetic field sensor (10, 21, 21') is positioned. Outside of said wall, the fringing flux (12) is opposed and is aligned with the useful flux (6). The magnetic field sensor is a magnetic field sensor element (10, 21, 21') located at a short distance from the wall (1, 29) and detects the field direction of the fringing flux (12); when the magnet (3, 23, 24) passes by, the fringing flux is superposed by the field (6) of the magnet (3. 23. 24). The magnetic field sensor (10, 21. 21') registers the change of field, which is then used to produce a switching signal.

Title: Rheology modification and modifiers

Granted: 2011-09-27
Abstract: We have now found that associative thickeners may be used in emulsions for use in explosive compositions, which associative thickeners provide for rapid and reversible changes in emulsion viscosity. Associative thickeners provide explosives emulsions having the desirable characteristics of (1) significant reduction in viscosity during pumping and (2) reestablishment of relatively high viscosity when pumping is terminated without damage to the emulsion components. It is believed that the associative thickener provides a network of physical linkages throughout the emulsion which network can be reversibly broken down.
Patent CA-2291546-C (CA)
Inventor: KUJA FRANK
IPC: H01J49/02
Filed: 1999-12-03
Granted: 2008-10-21
Abstract: A method is provided for monitoring the concentration of water vapour in an ion mobility spectrometer which measures the drift time of a selected ion, having a tendency to form clusters of water molecules. As these clusters are formed, the drift time of the ion varies, and by monitoring this variation in drift time, a measure of the concentration of water vapour can be made. If this exceeds a certain level, a warning can be given and/or the instrument disabled. Preferably, a comparison is made between two different ions, one having at least a moderate tendency to form clusters with water molecules, and the other having a weak tendency to form such clusters. By comparing the two drift times, a relatively accurate determination of water concentration can be made, and this can automatically allow for variations of drift times due to other causes.

Abstract: The invention relates to the use of intravenous contrast media for projection mammography as well as new devices for projection mammography. The invention therefore relates to the use of intravenous contrast media for the production of a diagnostic agent for projection mammography. Through the additional intravenous administration of contrast media, projection mammography achieves a sensitivity that is comparable to that of the most modern processes such as magnetic resonance tomography (MRT) while being considerably more versatile and avoiding the costs of MRT. The new process can be implemented simply and without special stress on the patients and provides a significant improvement in a) sensitivity to the detection of focal lesions in the breast, and b) additional information on the nature of lesions detected previously.

IPC: G09F3/00
Filed: 2000-03-03
Granted: 2005-10-04
Abstract: A double molding process whereby at least one sign is produced on a product while the product is molded. The product has an inner core and an outer cover. In the process, the inner core is molded with a first molding material. The inner core has at least one side provided with a groove in the shape of the sign to be produced. The inner core also has at least one other side provided with at least one channel leading within the inner core to the groove. The outer cover is then molded onto the inner core with a second molding material in such a manner that the one side of the inner core is not covered by the second molding material and thus remains visible. The channel of the other side and the groove of the one side are both filled up with the second molding material to produce the sign on the side of the product. This double molding process allows production of a sign, such as a name, a number, a logo, a trademark, or any other type of symbols conveying information, on a product while the product is molded, the sign lasting all throughout the working life of the product by virtue of its construction.
