摘要:
In a method of purifying an aluminium salt from a first aqueous aluminium salt solution of a raw material containing impurities, which comprise salts of at least one more noble metal than aluminium dissolved therein, a method of purifying a metal salt from inorganic impurities in an aqueous solution thereof is included. A plant for carrying out the method is also shown.
摘要:
A magnetic resonance imaging (MRI) device includes an inner gradient coil assembly proximate a patient positioning area, an outer gradient coil assembly proximate a magnet assembly, and a damping layer sandwiched between the inner and outer gradient coil assemblies.
摘要:
A support rod for supporting structures in a cryostat of a magnetic resonance system. The support rod has oppositely disposed stainless steel heads mounted on a glass reinforced plastic rod. The heads have threads on the main body thereof to minimize the length of the heads and thereby minimize heat condition.

A wire termination device (24) of the type having a body (25) with a first through-bore (26) into which protrudes wedging means (27) urged by spring means (28) and having a second through-bore (33) without wedging means, is characterised in that the second through-bore (33) is interrupted by a transverse notch (34), and each body portion (35A, 35B) separated by the notch (34) has a longitudinal entry slot into the second through-bore (33) with the slot (36A) in one portion (35A) at the opposite side of the body (25) to the slot (36B) in the other portion (35B), whereby the device (24) can be affixed for a horizontal wire (37) of a stock-fence by presenting the notch (34) to the wire (37) and then turning the device (24) so as to enable the wire (37) to pass through both slots (36A, 36B), whereafter a free end (38) of the wire (37) can be inserted into the first through-bore (26) after passing round an end post (39) to be secured in the device (24) by the wedging means (27).

摘要:
A transgenic non-human animal whose genome comprises a polynucleotide encoding human ICAM-1 domains D1 and D2 and preferably encoding human ICAM-1 domains D1 and D2 and host non-human ICAM-1 domains D3, D4 and D5. Methods for the production of such transgenic animals, screening methods using such transgenic animals, associated transgenes, constructs, vectors, and cells are disclosed. The transgenic non-human animal is a suitable model for studying human rhinovirus infection.
摘要:
The present invention provides for a cooling system for circulating a coolant to cool the patient bore. In one embodiment, that patient bore consists of two concentric cylinders separated by spacers running either longitudinally or helically. In another embodiment of the present invention, fluid may be passed either helically or longitudinally through tubes bonded to the outer diameter of the patient bore such that the parts of the bore that are exposed to the patient are directly cooled. In a third embodiment, the RF coil could form part of the patient bore, with the helical or longitudinal fluid channels surrounding the patient bore.
摘要:
A tool for pulling a wire (W) through a connector (C) or a terminal has a pair of levers (20, 24) pivoted together, one lever (20) having an abutment portion (23) for location of the connector (C) and the other lever (24) having clamping members (26, 28) for gripping the wire (W), characterised in that one lever (24) has a handgrip portion (25) articulated to a shank portion (40) for movement between an in-line position and a position inclined towards the handgrip portion (22) of the other lever (20), spring-loaded latching means (45) being provided between the handgrip portion (25) and the shank portion (40) for disengagement when the tension in the wire (W) reaches a value set by a knob (72) for loading the spring means and indicated by a pointer (73) against a scale (74).
摘要:
A method for creating a passive shim location in a gradient coil assembly of a magnetic resonance imaging system includes placing at least one tool in a volume between an inner gradient coil assembly and an outer gradient coil assembly. The tool includes an inner core and an outer sleeve. The inner core is removably housed in the outer sleeve. The volume is then filled with a bonding material. Once the bonding material has cured, the inner core is removed from the outer sleeve. The outer sleeve may also be removed from the volume.
