Patent CA-2295316-C (CA)
Title: Homogeneous human papilloma virus capsomere containing compositions, methods for manufacture, and the use thereof as diagnostic, prophylactic or therapy
Inventor: ROSE ROBERT C
IPC: A61P31/20
Filed: 1998-07-02
Granted: 2007-06-26
Abstract: The present invention relates to stable HPV capsomeres which express at least one virus-neutralizing conformational epitope of a native HPV L1 protein which are substantially incapable of assembly into virus-like particles. These capsomeres, because of their smaller size, and immunogenic properties are well suited for use in HPV vaccines and as diagnostic agents. Moreover, because of their smaller size (relative to VLPs), these stable capsomeres may be easily purified and should result in HPV vaccines of enhanced homogeneity.

Abstract: A liquid-handling installation utilizes an upstream and a downstream separator unit, each unit having a horizontal partition defining a treatment compartment below the partition and an overflow compartment above the partition. Each unit has an inlet opening and an outlet opening. Two conduits communicate the outlet opening of the upstream unit with the inlet opening of the downstream unit. The operating process includes: a) dividing into first and second substantially equal streams any liquid arriving at the inlet opening of the upstream unit; passing the first stream through the upstream unit treatment compartment, thence along the first conduit, thence over the downstream unit partition to the outlet opening of the downstream unit, and simultaneously passing the second stream over the upstream unit partition, thence along the second conduit, thence through the downstream unit treatment compartment, and finally to the outlet opening of the downstream unit; and b) when the total arriving liquid is greater than can be accommodated by the two treatment compartments, allowing the liquid to overflow all weirs and partitions and pass directly from the upstream inlet opening to the downstream outlet opening.

Title: Electronic system for monitoring a fifth wheel hitch
Inventor: GINOCCHIO MICHAEL H
IPC: B62D53/08
Filed: 2001-01-05
Granted: 2009-08-04
Abstract: An electronic system monitors a trailer hitch assembly that has a hitch plate with a throat for receiving a kingpin of a trailer and a locking mechanism for locking the kingpin in throat. The system determines whether the trailer hitch assembly is properly coupled to the trailer and includes a trailer sensor, a lock sensor, and a control circuit. The trailer sensor senses the position of the trailer relative to the trailer hitch assembly and the lock sensor senses the position of the locking mechanism. The control circuit is coupled to the trailer sensor and the lock sensor. The control circuit determines whether the trailer hitch assembly is properly coupled to the trailer by taking into account the sequence in which the trailer sensor and the lock sensor sense the respective positions of the trailer and the locking mechanism, as well as, the time periods elapsing between the sensing at such positions.

Granted: 2011-04-05
Abstract: In a wireless security system, the system controller includes one or more antennas for reception of signals from remote sensor-transmitter units. To detect antenna failure, the system controller generates a test signal with a known parameter and transmits this test signal via a first antenna. The system controller then measures the parameter of the corresponding test signal received, if any, via a second antenna, and compares the parameter of the corresponding test signal received to a predetermined threshold parameter.  When the parameter of the test signal received via the second antenna differs from the threshold by a predetermined amount, or predetermined margin for error, an antenna failure message is generated.

Title: Coupling device for providing a communications link for rf broadband data signals to a power line and method for installing same
Inventor: DIAMANTI PAOLO
IPC: H04B3/54
Filed: 2001-05-02
Granted: 2011-09-13
Abstract: A coupling device for providing a communications link for RF broadband data signals to a power line is disclosed. The coupling device comprises a high-pass filter element connected to the power line via a first port. The filter element allows RF broadband data signals to pass while low frequency signals are substantially attenuated. A second port connected to the high-pass filter element provides the RF broadband data signals to a RF broadband data signal line at a customer's premise. A drain coil connected to the high- pass filter element and connected to a ground provides grounding for low frequency signals but prevents the RF broadband data signals from being grounded. The second port and the drain coil are protected from power surges by a protective device connected in parallel to the drain coil. The coupling device is inexpensive to manufacture, essentially maintenance free, and easy to install. In a preferred embodiment such a coupling device is installable absent a step of disconnecting power to the power line which provides power to a customer's premise. Therefore, power supply to neighboring premises served by the same power line is not interrupted during installation.

Abstract: The present invention is a short flow milling process wherein finished product is rapidly isolated and removed from the milling process flow regime at early stages. The minimization of handling and the minimization or elimination of intermixing streams of various size gradations prevents size contamination that otherwise necessitates further sifting. Component parts are eliminated along with the accompanying handling and transfer equipment to create a compact and efficient milling regime. The size reductions enable the invention to be practiced in a mobile form. Therefore, the present invention relates also to a method for providing a mobile mill process.

Abstract: When the number of rotations of a drive source has fallen below a predetermined value, clutch moving members are disengaged from a clutch drum by clutch resilient members, and thus the clutch drum is caused, by a braking resilient member, to resiliently slide back to a predetermined braking position where a brake shoe is pressed against brake pads to apply the brakes. When the number of rotations of the source unit has increased above a predetermined value, the clutch moving members are caused to slide radially outward by centrifugal force in such a manner that the clutch moving members press and axially slide the clutch drum to a non-braking position against the bias of the braking resilient member, so that the brake shoe is disengaged from the brake pads to release the brakes.
