There is provided a magnetic clamping device (10) for magnetically clamping to a magnetically attracted material (30). The device comprises at least one permanent clamping magnet (14, 44) for magnetically clamping to the magnetically attracted material wherein the magnet is movable relative to the magnetically attracted material from a position remote from the magnetically attracted material to a clamping position for the clamping of the material by the magnet. The device also includes damping means (22, 24) for damping the movement of the clamping magnet to the clamping position. The damping means biases the clamping magnet away from the magnetically attracted material to assist release of the clamping magnet from the magnetically attracted material. In addition, the device has support means (16, 40, 58) to which the clamping magnet is mounted for the relative movement of the clamping magnet from the remote position to the clamping position and for withdrawing the clamping magnet relative to the magnetically attracted material to release the magnetically attracted material. There is also provided a method for clamping the magnetically attracted material (30) using the clamping device (10). The clamping device may, for example, be a device for securing a load to the magnetically attracted material, a lifting device, a device for holding a work piece in position, or a welding clamp.

A steerable guidewire. The steerable guidewire is fabricated includes an outer tube, an inner tube, a hub, and a distal articulating region. The steerable guidewire hub can be removed to permit advancement of catheters over its proximal end followed by re-attachment of the hub to permit deflection of the distal end of the steerable guidewire.

Devices and methods provide for enabling a user to use a single user authentication device such as smart-card reader, such that the user is capable of securely interfacing with two or more isolated computers and enabling the user to authenticate and remain authenticated at multiple computers at the same time. Once the user removes the smart-card from the smart-card reader, the authentication session on all coupled computers is terminated at once. The user authentication device comprises: an authentication module connected via a channel selection switch to one of a plurality of channels, each interfacing with a respective coupled computer.

This application provides a catalyst for producing paraxylene by co-conversion of methanol and/or dimethyl ether and C 4 liquefied gas, and preparation and application thereof. The catalyst is an aromatization molecular sieve catalyst with a shape-selective function co-modified by bimetal and siloxane compound. Methanol and/or dimethyl ether and C 4 liquefied gas are fed in reactor together, wherein aromatization reaction occurring on a modified shape-selective molecular sieve catalyst. The yield of aromatics is effectively improved, in which paraxylene is the main product. In products obtained by co-conversion of methanol and/or dimethyl ether and C 4 liquefied gas, the yield of aromatics is greater than 70wt%, and the content of paraxylene in aromatics is greater than 80wt%, and the selectivity of paraxylene in xylene is greater than 99wt%.
摘要:
A closed loop catheter useable for heat exchange is manufactured by forming a plurality of generally transverse bore holes though a flexible, multilumen catheter body, lacing a tube trough the bore holes so that loops of the tube protrude from the catheter body, connecting one end of the tube to an inflow lumen of the catheter and connecting the other end of the tube to an outflow lumen of the catheter. A heated or cooled heat exchange medium may then be circulated through the tube while the catheter is inserted in the vasculature of a subject, thereby resulting in heat exchange between the subject's flowing blood and the heat exchange medium being circulated through the tube.
