Patent MX-9707463-A (MX)
Title: Medical syringe and self-retracting needle apparatus.
Inventor: THORNE GALE H
IPC: A61M5/31
Filed: 1997-01-30
Abstract: Method and apparatus associated with safe retraction of medical needles after use. Embodiments are disclosed for combinations comprising medical syringes and self-retracting needle systems (10). An energy-storing, needle-retracting mechanism comprises an elastic tubing (180) which also is taught to perform a plurality of functions comprising the storing of force by which a medical needle (140) is retracted, slidable seals (150), normally closed valves (160) and dynamic volume control by which fluid regurgitation upon needle retraction is voided. Selective, constrictive control of the internal volume of the tubing (180) when stretched effectively inhibits regurgitant flow from the needle (140) as the tubing (180) relaxes while retracting the needle (140). In all embodiments, needle retraction is initiated by forces applied in a direction transverse to the long axis of the needle (140) using but a single hand. The syringe (10) may be used in a plurality of modes such as a standard syringe or as a pre-filled syringe. Methods for making and assembling the combination are also disclosed. Invention manufacture requires only a minimal number and complexity of parts such that a projected manufacturing cost is potentially low enough to permit the apparatus to be cost competitive with contemporary combinations of hypodermic syringes and non-self-retracting needle systems.

Title: Thermal camouflage material
Inventor: KARLSSON LARS
IPC: F41H3/02
Filed: 1987-12-30
Abstract: The invention relates to a thermal camouflage comprising a strengthening layer (4), e.g. a woven material, on which a polyethylene film layer (1), metallized on one side, has been laminated with the aid of fusion adhesive (3). On lamination the surface is embossed such as to make it mat. Since the polyethylene is transparent for infrared, it has low self-radiation. By means of the metal layer (2) there is obtained radiation insulation so that the outer layer (1) is in a thermal equilibrium which is hardly affected, e.g. by a warm object which is covered with the material, and the outer layer has a low emission ability of about 0.6-0.8, depending on thickness and pigmentation. By applying further layers (5), patchy images may be obtained with infrared reproduction in the wavelength ranges of 3-5  mu m and 8-14  mu m.

Title: Industrial waste gas purification process - uses isotope irradiating impurities in passage and which are then collected
IPC: B03C3/38
Filed: 1974-02-14
Abstract: The gases flow through a passage, in which there is situated a source isotope producing powerful radiation in a high dosage. This generates a radiation field with energy levels of at least 200,000 eV and radiation doses greater than 1 Rad. A connection device brings the isotope into a state generating the radiation field in the passage and dispensing a sufficiently high dosage. The radiation is mainly confined to the passage by a shield round it. A collector device connected with the radiation zone accumulates the irradiated purities. The isotope can be a crude nuclear fission product, giving a radiation field of at least 1 MeV with a minimum dosage level of 1 kRad.
