Title: Bow quiver for archery
Inventor: SODARO JOHN C
IPC: F41B5/20
Filed: 1998-07-27
Abstract: A bow-mounted archery quiver having a twin-hood design provides improved noise reduction and balance features. Arrows are held in a vertical position and may be removed in either of two directions relative to the archer. An arrow-holding element is formed from an elastomeric material, preferably a viscoelastic polyurethane elastomer. The quiver is provided with an offset configuration so as not to interfere with operation of the bow. The quiver may be mounted to the side of the handle riser of a bow, using a dovetail mounting arrangement. A quick release mechanismallows for positive one-hand push-button release of the quiver from the archery bow.

Title: Process for making a low density detergent composition by agglomeration followed by dielectric heating
Inventor: FRANCE PAUL AMAAT
IPC: C11D11/00
Filed: 1997-05-01
Abstract: A process is provided which produces a low density (below about 600 g/l) detergent composition directly from starting detergent ingredients. The process employs dielectric heating means, such as a microwave (MW) dryer or a Radio Frequency (RF) dryer, to "puff" agglomerates formed by agglomerating a surfactant paste or acid precursor thereof and dry detergent materials. The process does not require the use of conventional spray drying towers, and therefore, is more efficient, economical and flexible with regard to the variety of detergent compositions that can be produced in the process.

Inventor: HATT RAYMOND JOHN
IPC: C13B10/06
Filed: 1997-05-09
Abstract: Cette invention se rapporte à un appareil conçu pour broyer la canne à sucre de façon à en extraire le jus. Ledit appareil possède des cylindres broyeurs, l'un au moins de ces cylindres comportant des voies d'écoulement du jus qui sont temporairement obstruées par la bagasse après l'entrée du jus dans lesdites voies d'écoulement. La rotation supplémentaire des cylindres permet d'extraire le jus piégé dans le matelas de cane et le bouchon de bagasse est retiré par raclage de la partie supérieure de la voie d'écoulement de manière à permettre l'écoulement du jus. Le jus extrait du matelas de cane n'est pas réabsorbé par ledit matelas. On améliore ainsi l'efficacité d'extraction du jus. L'invention concerne d'autres perfectionnements du procédé d'extraction qui consistent à utiliser des paires de cylindres broyeurs juxtaposés verticalement de telle sorte que le matelas de cane se déplace suivant une direction généralement verticale.

Title: Cooled stationary blade of a gas turbine
Inventor: KITAMURA TSUYOSHI
IPC: F01D9/04
Filed: 1998-04-28
Abstract: In a cooled gas turbine stationary blade, both steam cooling and air cooling are utilized to reduce the amount of cooling air. In the stationary blade having outer and inner shrouds 1, 21 and steam passages 10A, 10B, 10C, 10D and 10E which are communicated with each other and in which a sealing air feed tube 2 passes through a central portion thereof, steam covers 3, 4 are provided in the outer shroud 1, and steam S is introduced from a steam feed port 5. The steam S passes through serpentine passages 10A to 10E and is recovered from the steam outlet 12 after cooling the central portion of the outer shroud 1 by means of an impingement plate 8. A portion of the steam of the passage 10A is introduced from the impingement plate 25 to a steam sump 24 to cool the central portion of the inner shroud 21 and pass through the passage 10D to be recovered from the steam outlet port 12. On the other hand, cooling air is fed from cooling air feed ports 6 and 26 to peripheral portions of the outer and inner shrouds 1, 21, and is discharged to the outside from the rear sides thereof, respectively, and the cooling air is further fed from a cooling air feeding port 7 to the passage 10E on the rear edge of the blade to cool the rear edge of the blade. Only the narrow portions where it is difficult for the steam to pass are air-cooled to thereby reduce the amount of the cooling air.

IPC: A61K47/48
Filed: 1997-09-25
Abstract: Hydrolyzable prodrugs according to the present invention are activated by proteases located in the cell membranes of metastatic cells to yield active anticancer drugs that can be taken up by the metastatic cells. In general, a hydrolyzable prodrug according to the present invention comprises an aminoterminal capped peptide that is a substrate for a peptidohydrolase located on the surface of a metastatic cell covalently linked to a therapeutic drug through a self-immolating spacer of sufficient length to prevent the occurrence of steric hindrance. The therapeutic drug is typically an anticancer drug. The anticancer drug is typically doxorubicin, taxol, camptothecin, mitomycin C, or esperamycin. Typically, the peptidohydrolase that hydrolyses the substrate of the hydrolyzable prodrug is cathepsin B.

Patent CA-2265205-A1 (CA)
Inventor: MEINEL HOLGER
IPC: G01F23/284
Filed: 1999-03-11
Abstract: In order to measure the liquid level in a tank with the aid of a microwave transmitting/receiving device and a waveguide extending into the tank, it is suggested that the waveguide be designed for a precise and scalable measuring of the filling level, in such a way that it has clear and constant wave propagation characteristics for a wave with the operating frequency of the microwave device. In particular, this is achieved by dimensioning the cross section of a hollow conductor in such a way that the operating frequency lies in the unambiguous range of the hollow conductor.

Title: Assembly for supporting the floating roofs of tanks for storing liquids
Inventor: VELLOSO PRADEL LUIS ADOLFO
IPC: B65D88/34
Filed: 1998-02-17
Abstract: An assembly for supporting the floating roofs of tanks for storing liquids, particularly hydrocarbons, comprises a support leg (5), a guide (7) rigidly fastened to the floating roof which it is desired to support, and a locking pin (11). The lower end (16) of the guide (7) acts as a support for the floating roof when the assembly is in the operating mode. In this situation, the support leg (5) has no structural function and may be withdrawn, and the locking pin is installed at the top of the guide (7) coaxial with the vertical axis of the guide, so as to close the orifice via which the support leg passes. When it is necessary to place the roof in the maintenance mode, the support leg is again inserted in the orifice via which the guide (7) passes and the locking pin (11) passes through the orifices (13) of plates (12) which are rigidly fastened to the top of the guide (7), which allows the assembly to be locked. The orientation of the locking pin (11) enables an operator remotely to ascertain the operating status of the floating roof.

Patent CA-2288532-A1 (CA)
Inventor: LAUBE HORST
IPC: A61F2/06
Filed: 1999-11-04
Abstract: To coat a surface of a medical implant such as an organ part or a synthetic prosthesis with a coating of living cells, the implant is inserted and fixed into a receiving container which is at least partially filled with a nutritive liquid medium containing the coating cells in suspension. Then the receiving container is rotated respectively about two distinct rotation axes, whereby preferably the two rotation motions are independently controllable and the two axes are substantially perpendicular to each other. Each of the two rotation motions can be a continuous rotation through 360°, or a stepwise intermittent rotation through successive rotational angle steps. The parameters of the two rotations about the two axes can be combined as needed for a particular application, for example a continuous rotation about one axis combined with a stepwise rotation about the other axis.      The time period and rotational speed of each rotation can also be independently controlled. A uniform and complete coating of cells on all surfaces of the implant is achieved.

Patent CA-2292002-A1 (CA)
Inventor: KULL ROBERT C
IPC: B60T13/66
Filed: 1999-12-09
Abstract: A low power ECP tramline communication method is provided wherein power consumption by each freight car's on-board ECP transceiver is minimized such that it can be powered indefinitely by a standard locomotive battery. The low power communication method includes normally maintaining each car's ECP transceiver in a sleep mode until signaled by the locomotive master controller to wake it up. The wake-up command for the ECP  transceiver can be sensitive to the length of the message sent by the MC. Alternative, or additional methods of identifying a wake-up message from the MC can include using the signal strength of the message and making the wake-up command sensitive to the ECP trainline power status. In the latter case, detection of zero tramline power is a signals to wake-up the ECP transceiver.
