摘要:
A gas mixture for preserving fish and sea-food products, comprising carbon dioxide, oxygen and argon with partial pressures in the following range:______________________________________ CO.sub.2 50%-68% O.sub.2 5%-20% Ar 27%-45% ______________________________________ This mixture slows down enzymatic reactions and microbiological development at the surface and inside the fish or sea-food product.
摘要:
A gas mixture comprising carbon dioxide, oxygen and argon is provided to extend the shelf life of sea-food products and fish from 15 to 21 days at the storage temperature of 4.degree.0 C.Comparison is made with similar mixtures comprising nitrogen in lieu of argon which shows the unexpected results obtained with the mixtures of the invention.
摘要:
An improved expandable stent for implantation in a body lumen, such as an artery, and an improved method for making it from a single length of tubing. The stent consists of a plurality of radially expandable cut cylindrical elements generally aligned on a common axis and interconnected by one or more interconnective elements, the elements having a rectangular cross-section from cut-to-cut. The individual radially expandable cylindrical elements are disposed in an undulating pattern. The stent is manufactured by direct laser cutting from a single metal tube using a finely focused laser beam passing through a coaxial gas jet structure to impinge on the working surface of the tube as the linear and rotary velocity of the tube is precisely controlled.
摘要:
A method for forming a stent and for also forming channels in the outer surface of selected regions of the stent structure. The method includes impinging a laser beam generated by a diode pumped Q-switched pulsed Nd/YAG laser operating at the third harmonic on an outer surface of a stent and controllably machining channels in the outer surface of the stent. The depth of the channels may be controlled by adjusting the power and pulse rate of the laser, and also by adjusting the rate at which the stent moves relative to the laser beam.

An external cervical fixation system includes a body configured to be secured to a patient, an attachment arm extending from the body, a bone screw, and a mounting fixture. The bone screw is mounted to the attachment arm, and has a threaded distal tip that is configured for threaded engagement with the patient's skull. The mounting fixture joins the attachment arm and the bone screw. The mounting fixture is configured to allow mounting and removal of the attachment arm and the bone screw when the bone screw is threadedly engaged with a patient's skull. The body can be adjusted independently of the bone screw.

摘要:
A method of verifying the accuracy or authenticity of alphanumeric magnetic data on a document, wherein the configuration of a pictorial or graphic magnetic reference image in the document is made visible by bringing movable particulate magnetic material into proximity therewith such that the particulate magnetic material takes up a distribution corresponding to the magnetic field of the reference image; and the magnetic image configuration thus revealed is compared with the reference image to identify any significant disconformity suggesting past exposure of the document to a magnetic field capable of altering said magnetic data.
摘要:
A magnetically-activatable sheet product is provided comprising a pair of laminated outer sheets between which is a magnetic layer comprising magnetically-activatable particles in a binder matrix, the outer sheets having sufficient opacity to mask the appearance of the magnetic layer, at least one of the outer sheets being provided on its outward facing surface with a coating which comprises either microcapsules containing a solution of at least one chromogenic material, or dispersed droplets containing at least one chromogenic material in a pressure-rupturable matrix, or a colour developer composition, or both microcapsules containing at least one chromogenic material and also a colour developer.
摘要:
Pantoprazole sodium multiparticulates are described which avoid sticking to nasogastric and gastronomy tubes. The pantoprazole multiparticulates have a spheroid core of pantoprazole or an enantiomer thereof, or a salt thereof, a surfactant, and a distintegrant; a sub coat which is comprised of hydroxypropyl methylcellulose (hypromellose) and water, an enteric coat on the sub-coat, and a final seal coat over the enteric coat, which is composed of hydroxypropyl methylcellulose (hypromellose) and water.
