Title: Packaging with pull-open closure
Inventor: MARBLER CLAUDE A
IPC: B65D75/62
Filed: 2001-03-09
Abstract: The invention relates to a flexible packaging (1) made from a packaging film, in particular a pouch type of packaging with at least one closure seam (5) and containing a pull-open closure which exposes an opening for removing the contents. The packaging (1) also contains a tear-arresting means (4) that lies on a tearing line (3) in the direction of tearing (x). The tear-arresting means may be in the form of a circular-shaped opening or, running essentially transverse to the line of tearing (3), a cut or partially cutting line, perforation or the like line of weakness which only partly penetrates the packaging film. After opening the packaging and on meeting the tear-arresting means (4), a tearing zone progressing along the tearing line (3) is no longer effective and the tearing process is stopped.  This way the part which is torn (9) is prevented from being separated completely from the packaging.

Abstract: A dry krill powder wherein deterioration of lipids can be sufficiently prevented without resort to any antioxidant. The dry krill powder is characterized by containing all of the krill components. The proteases contained in the krill material have been completely inactivated. Heating is the only means for denaturing the proteins and inactivating the proteases contained in the krill material. The production process involves no chemical treatment for eliminating moisture or inactivating or inhibiting the proteases. Moreover, the process is free from the formation of waste liquor.  This production process comprises lightly dehydrating caught krill, then grinding the same and drying by heating. Namely, the moisture contained in the krill is inactivated exclusively by heating so as to broaden the application range and, moreover, impart a high keeping quality. Thus, this production is a so-called zero-mission performance free from any waste.

Abstract: Surgical methods and instruments are disclosed for performing port-access or closed-chest coronary artery bypass (CABG) surgery in multivessel coronary artery disease. In contrast to standard open-chest CABG surgery, which requires a median stemotomy or other gross thoracotomy to expose the patient's heart, post-access CABG  surgery is performed through small incisions or access ports made through the intercostal spaces between the patient's ribs, resulting in greatly reduced pain and morbidity to the patient. In situ arterial bypass grafts, such as the internal mammary arteries and/or the right gastroepiploic artery, are prepared for grafting by thoracoscopic or laparoscopic takedown techniques.  Free grafts, such as a saphenous vein graft or a free arterial graft, can be used to augment the in situ arterial grafts. The graft vessels are anastomosed to the coronary arteries under direct visualization through a cardioscopic microscope inserted through an intercostal access port. Retraction instruments are provided to manipulate the heart within the closed chest of the patient to expose each of the coronary arteries for visualization and anastomosis. Disclosed are a tunneler and an articulated tunneling grasper for rerouting the graft vessels, and a finger-like retractor, a suction cup retractor, a snare retractor and a loop retractor for manipulating the heart. Also disclosed is a port-access topical cooling device for improving myocardial protection during the port-access CABG procedure. An alternate surgical approach using an anterior mediastinotomy is also described.

Filed: 2000-10-06
Abstract: Un dispositif de coussinet de préhension (50) comprend un élément en silicone (98) doté d'une membrane hydrophobe. L'élément en silicone adhère à un élément en acier inoxydable pourvu d'une agrafe en forme de C (62) à son extrémité distale en vue de saisir le bout d'une mâchoire de pince. Un élément moulé en polypropylène s'étend à travers un trou dans l'élément en métal et comprend une projection (78, 120, 122) qui s'étend à travers une ouverture dans l'élément métallique situé près de l'extrémité proximale du coussinet. Cette projection s'adapte à un trou (46, 48) dans la face de la mâchoire de la pince pour maintenir le coussinet de préhension fixé à la mâchoire jusqu'à ce qu'il soit déplacé par la force par coulissement et courbure. L'utilisation d'une agrafe en acier inoxydable (62) avec la projection en polypropylène permet de minimiser l'épaisseur du dispositif de coussinet, tandis qu'elle pare à l'adhérence à des tolérances de fabrication très proches afin d'assurer une adaptation adéquate de la projection dans le trou de la mâchoire.

Title: Method of drying wood and a system therefor
Inventor: CHOI SUN TAE
IPC: F26B21/10
Filed: 2000-05-19
Abstract: Disclosed is a method of drying timbers loaded in a drying chamber, which comprises the steps of heating the drying chamber by a heating system up to a temperature of 80 to 100 ~C, subjecting the timbers to vacuum blowing by connecting the inside of the drying chamber with a vacuum chamber (receiver)  evacuated by a rotary pump until the inside pressure of the drying chamber drops to 1 to 10 mmHg, disconnecting the inside of the drying chamber from t he vacuum chamber, connecting the drying chamber with the atmosphere. When the inside of the drying chamber is connected with the vacuum chamber, the moisture content of the timbers is sharply reduced, so that their temperatur e sharply drops. Thereafter, when it is disconnected from the vacuum chamber, and connected with the atmosphere, the inside temperature of the drying chamber is again increased. Meanwhile, the heating system is worked during t he whole process. The above steps constitute one cycle that is sequentially repeated until the moisture content of the timbers drops to a desired level.  Preferably, the connection between the drying chamber with the vacuum chambe r is made in 0.1 to 0.5 seconds. Pressure release is made in the vaccum for 0. 5 to 5.0 seconds until reaching equilibrium moisture. The blow-down in the vacuum is carried out by a heat carrier with a temperature of 80 to 150 ~C until reaching the volume average material temperature of 80 to 90 ~C with t he subsequent pressure release in the drying chamber lower than the equilibrium , thus providing high-speed vacuum blowing.

Abstract: Method and system for analyzing trends. A host system is linked with a plurality of point-of-sale systems. A master terminal may also act as a complete point-of-sale system. The point-of-sale systems store transactional data relating to purchases made. At the host level or at the master terminal, desired trends relating to the sales of products are identified by the retailer or manufacturer. Desired responses for responding to the trends are determined. A trend analysis system, using the transactional data, generates a response to the trends using the information linking the trend with the desired response. The instruction are sent to modify the operation of the point-of-sale system to respond to the trends. The response may be a promotional offer designed to make sales meet the desired trends, such as a coupon, a discount or a price reduction.

Title: Method for determining amount of water to be added to a nicd cell

IPC: H01M10/48
Filed: 2000-08-18
Abstract: Deficiencies in the electrolyte level of the cells (12) of NiCd battery (10) can be detected by measuring the internal resistance of the cells (12).  Initially, data is collected for a battery type and capacity, correlating measured internal resistance with the amount of water that must be added to bring the cell resistance to an acceptable value. Subsequently, cells of other batteries of the same type and capacity can be measured to determine how much water must be added and the levels quickly restored. The polarization value of the cells can be used lieu of the internal resistance in the same fashion.
