Title: Rotor assembly for a combine
Inventor: FRANCIS ROBERT L
IPC: A01F7/06
Filed: 1992-11-10
Granted: 1995-12-26
Abstract: A combine with a rotor assembly having an impeller at a forward end and a cylindrical drum axially extending from the impeller.  The rotor assembly is provided with a series of thresher elements having a smooth outer material engaging surface secured about the circumference of the rotor in generally helical arrays and is provided with a plurality of linearly extended thresher elements each having a smooth outer material engaging surface and which are secured about that end of the drum adjacent the impeller.  When the rotor assembly is operated, the plurality of linearly extended thresher elements form a paddle like mechanism which extends to a forward end of the rotor assembly to offer enhanced control over the abundance of material being threshed at a forward end of the rotor assembly while simultaneously minimizing damage to the crop thereby maximizing the farmer's profit.

Title: Method of transferring between centres the handling of an active connection between a user, on the one hand, and a mobile terminal, on the other hand
Inventor: VAN NIELEN MARCUS JOSEPHUS JOH
IPC: H04Q3/00
Filed: 1992-12-03
Granted: 1996-11-19
Abstract: Known methods of transferring between centres the handling of an active connection between a user and a mobile terminal in a telecommunication system designed for mobile communication generally have the disadvantage that the routing obtained is inefficient. By investigating botha first route between a first switching centre and the user and a second route between a second switching centre and the user for common centres which are able to handle call control and connection control separately, of which the common centre situated nearest the first switching centre is designated as central intelligence point or, if the latter is not found, by designating the centre situated nearest the user as central intelligence point and then setting up a connection between a central intelligence point found in this way and the second switching centre, the most efficient routing is obtained.

Granted: 2006-07-04
Abstract: A helmet that prevents catastrophic neck injuries; in the preferred embodiment, for hockey, a high-impact plastic casing is snagged on top of the player's head by cantilever supports from the inside sides of the casing; a flange at the bottom of the casing is formed so that a collision such as a head-on collision on top of the head will drive the helmet into contact with the torso, thus transmitting all collision force to the torso. The top of the helmet is high enough that the top of the head does not contact the underside of the top of the helmet under the peak collision force. Further, in the most dangerous high-incident-angle collisions, a tip projecting rearwards from tho top of the helmet, in conjunction with rollers on the top surface, act to position the helmet for symmetrical transmission of force axially. A second embodiment, without the tip and rollers, is also described, as is a third with a rear extension segment to prevent the flange from contacting the back of the neck in cases of rearwards flexure of the neck.

Title: Process for the obtention of a biological adhesive made of concentrated coagulation factors by acidic precipitation
Inventor: BUI-KHAC TRUNG
IPC: A61L24/10
Filed: 1994-01-18
Granted: 2005-06-28
Abstract: The present invention relates to a process of making a concentrate of coagulation proteins starting with whole human or animal plasma. This concentrate is used as a biological adhesive when extemporaneously mixed to thrombin. The concentrated proteins include mostly fibrinogen, fibrin stabilizing factor (factor XIII) and fibronectin. The claimed process has the advantage of being short of execution while providing an excellent yield of coagulable proteins. No protease inhibitor has to be added during the process. The process involves steps of acidic precipitation in presence of amino-6 hexanoic acid which prevents co-precipitation of plasminogen with the desired coagulable proteins. The proteins so obtained are very stable after reconstitution in water for at least 24 hours at room or body temperature. After mixing with thrombin, the adhesive shows excellent strength arid biocompatibility.

Title: Suction catheter system
Inventor: CRAMER BERNHARD
IPC: A61M1/00
Filed: 1994-06-23
Granted: 1998-12-01
Abstract: A suction catheter system for drawing off thrombi and emboli from blood vessels has a central catheter and an outer catheter which coaxially surrounds the latter. For introducing the catheter system into a vessel and for widening the said vessel, a guide wire and a dilator are provided. A blood clot is removed by means of a vacuum which is applied to the central catheter. Should the central catheter become blocked by the blood clot as the latter is drawn off, the central catheter can be withdrawn from the outer catheter and can be replaced by a new central catheter. This new central catheter can be connected to the suction device and the procedure continued. Instead of introducing a new central catheter, the suction procedure can also be continued via the outer catheter by means of the latter being connected to the suction device after the central catheter has been removed.
