Title: Method for collecting hemolymph of insects
Inventor: MIYAZAWA MITSUHIRO
IPC: C07K14/435
Filed: 1997-04-28
Abstract: The present invention herein provides a method for collecting insect hemolymph which permits the collection of hemolymph, at a time, from a vast number of insect bodies, which does not cause any scattering of the hemolymph during collection thereof, which may widely be used, which permits the collection of the hemolymph free of unnecessary tissues or the like and which can inhibit the melanization of the collected hemolymph.

Patent CA-2232670-A1 (CA)
Inventor: TSCHUDI JEAN-PIERRE
IPC: C05F17/00
Filed: 1997-05-21
Abstract: A thermo-mechanical method for municipal wastes that are prepared for aerobic composting is proposed, with the sorted wastes being pre-dried (depending on consistency), mixed with vegetable matter and ground up, thus creating a quasihomogeneous mixture of a new consistency. During this process, the material is rendered practically hygienic and odor-free, and increases its specific surface area, because a loose, springly and fluffy structure is created. The structure thus obtained is suitable for post-composting, because even when heaped in a clamp, it remains loose and fluffy enough during and after composting so that partial input of excess atmospheric oxygen is assured, and if microporous cover sheeting and forced ventilation are used, it will be converted to high-quality recycling humus of Ripeness Class V within two or three weeks, without mechanical turnover.

Patent CA-2238028-A1 (CA)
Inventor: LAI CHING-SAN
IPC: A61K38/00
Filed: 1996-11-12
Abstract: In accordance with the present invention, there are provided combinational therapeutic methods for the in vivo inactivation or inhibition of formation (either directly or indirectly) of species which induce the expression of nitric oxide synthase, as well as reducing nitric oxide levels produced as a result of .No synthase expression. In contrast to the inhibitory approach described in the prior art (i.e., wherein the function of the enzymes responsible for nitric oxide production is inhibited), the present invention employs a combination of inactivation (or inhibition) and scavenging approach whereby the stimulus of nitric oxide synthase expression is inactivated, or the production thereof is inhibited, and overproduced nitric oxide is bound in vivo to a suitable nitric oxide scavenger. The resulting complexes render the stimulus of nitric oxide synthase expression inactive (or inhibit the production thereof), and nitric oxide harmless. The resulting complexes are eventually excreted in the urine of the host. Further in accordance with the present invention, there are provided compositions and formulations useful for carrying out the above-described methods.

Title: Improvements relating to containers
Inventor: BRITTON CHARLES JONATHAN
IPC: B29C49/54
Filed: 1996-11-29
Abstract: A container is made in two stages from material such as thermoplastics that is deformable when heated. In the first stage a preform (1) is injection moulded, the mould parts easily releasing a tubular body (2) with a closed end. In the second stage the still heated preform (1) is blow moulded, possibly with some preliminary mechanical stretching, the blow pin being applied to the open end.  The closed end of the body is stretched over a multi-part section (7, 8) of the mould which shapes the base of the container into an indent with an undercut formation, the cross section being generally omega-shaped. The multi-part mould section has a central tapered core (8) surrounded by an array of segments (7), the core (8) being fully inserted to spread the segments (7) for moulding, and being retracted to allow the segments (7) to close up and release the container after moulding. The divisions (12) between segments (7) produce ribs in the indent which provide added strength.

Filed: 1997-10-17
Abstract: The method allows determination of the re-circulation of blood in a vascular access (11) of a patient whose blood is being subject to treatment (12) in an extra-corporal circuit. The process includes regulating the flow rate of blood in the extra-corporal circuit and a predetermined value (QB), and determining a first value (HGBA0) of the parameter representing the concentration of blood in the extra-corporal circuit. A variation in the amplitude (QUF) of the ultra-filtration flow rate in the treatment appts. (12) is effected. A second value (HGBA3) of the concentration parameter is then determined. The re-circulation (AR) of the blood in the extra-corporal circuit is determined on the basis of the blood flow rate (QB), the ultra-filtration flow rate amplitude (QUF) and the two parametric flow rate measurements.
