Title: Method for transferring a reel, and a reel-up
Inventor: MAEKINEN RISTO
IPC: B65H18/26
Filed: 2002-08-27
Abstract: In the method for transferring a reel in a reel-up for paper or paperboard, a continuous paper or paperboard web (W) is guided via a reeling member (1) to form a machine reel (R) around a reel spool (2), the ends of which are supported on top of supporting surfaces that move in relation to the reeling member (1) in the radial direction of the machine reel under the guidance of a supporting frame (10) located on both sides of the reel, in accordance with the change of position of the reel spool (2). The supporting surfaces (3a) are transferred as a part of the motion of the transfer devices moved by means of force devices (5), such as reeling carriages(4) while the supporting surfaces are coupled to the transfer devices and are supported by tracks, the height position of which is between the supporting base for the supporting frame (10), such as the floor level, and the supporting surfaces (3a).

Title: Genetic engineering of streptavidin-binding peptide tagged single-chain variable fragment antibody to venezuelan equine encephalitis virus
Inventor: NAGATA LESLIE P
IPC: C07K16/10
Filed: 2004-02-24
Abstract: A recombinant gene encoding a single-chain variable fragment (scFv) antibody against Venezuelan equine encephalitis virus (VEE) being cloned into a prokaryotic T7 RNA polymerase-regulated expression vector was disclosed. A streptavidin-binding peptide (SBP) sequence fused to a 6His tag is then attached downstream to the scFv gene. The recombinant fusion protein is expressed in bacteria and then purified by immobilized metal affinity chromatography. ELISA and Western blotting results revealed that the fusion protein not only retained VEE  antigen binding and specificity properties similar to those of its parent native monoclonal antibody, but also possessed streptavidin-binding activity. This discovery obviates the need for chemical biotinylation of antibodies and the risk associated with antibody denaturation and provides a stable and reproducible reagent for rapid and efficient immunoassay of VEE.

Title: Latch with uni-directional power release mechanism
Inventor: LARSEN CHRISTOPHER L
IPC: E05B65/12
Filed: 2002-09-17
Abstract: A latch (1) has a unidirectional power release mechanism. The mechanism has a rotatable gear (7) with a boss (9) on the gear, a motor (3) for rotating the gear (7) to orbit the gear boss through an operating cycle of the mechanism, a ratchet (29) movable from a latched position to an unlatched position, a pawl lever (21), a pawl (22), and a toggle (11) which moves between a first toggle position and a second toggle position to set the limits of the operating cycle of the mechanism. The toggle (11) pivots in response to the orbiting gear boss (9) and presents a stop for the gear boss (9) at the end of the operating cycle. The gear boss (9) effects movement of the pawl lever (21) to effect unlatching and stops the orbiting gear boss (9) when it encounters the stop.  The toggle (11) is pivoted back removing the stop in response to the ratchet (29) rotating to the latched position.

Abstract: The invention concerns a portable device for defrosting surfaces covered with frost or ice. The invention provides a device for defrosting frosted surfaces economically, cleanly and without risk of further frosting following previous scraping. By means of its shell (1), it generates a chamber between the windscreen and the device, where the temperature is sufficiently heated to melt the frost. The temperature is raised beneath the shell (1) through a heating element (6) mounted in a protective slide (4) by two heat-resistant cover plates (5 and 10). The combination of said system with a flexible scraper blade (3), arranged perpendicular to the forward moving direction (12) enables removal of the melted frost or ice residue. The combination of a heated bubble (1 and 6) and a scraper blade (5 and 10) on the same side and positioned to operate in the same direction enables de-icing in one single passage over the entire width of the device.

Title: Tree pusher
Inventor: SMITH WAYNE J
IPC: B66F3/08
Filed: 2003-06-16
Abstract: A tree pusher for safely felling trees.

Abstract: A protective device that is used in a medical suction system withdrawing liquids from a patient. The device is located upstream of a vacuum regulator and protects that regulator and other downstream components from contacting the liquid being withdrawn from the patient. The protective device has an inlet and an outlet and an actuator mechanism that can move between a contracted position where a gas can communicate through the protective device between the inlet and the outlet and an expanded position where the actuator mechanism occludes both the inlet and the outlet to shut off the vacuum supply to the patient. An electrical circuit having a pair of sensing electrodes provides an electrical discharge to trigger a shape-metal alloy wire to move the actuator mechanism from the contracted position to the expanded position when the sensing electrodes detect the presence of a liquid therebetween.

IPC: A61K35/16
Filed: 2003-08-01
Abstract: It is intended to easily and less expensively provide a highly active platelet rich plasma. A method of preparing a platelet rich plasma which involves the step of adding a water-soluble polymer to collected whole blood. By adding, for example, a polyamine such as poly-L-glutamic acid, an acidic polysaccharide such as hyaluronic acid or a vinyl polymer to whole blood and allowing to stand for a definite time, erythrocytes are selectively and cumulatively aggregated and precipitated. Thus, a highly active platelet rich plasma containing platelets as well as fibrinogen-rich plasma components and leucocytes can be obtained as the supernatant. It is also intended to provide this platelet rich plasma, the utilization thereof as an agent for promoting the repair of a tissue and/or an organ, etc., and a kit for preparing a platelet rich plasma.
