Title: Weight distributing hull and keel support for boat trailer frames
Inventor: CARRICK LARRY K
IPC: B60P3/10
Filed: 1993-09-02
Abstract: In the present hull and keel support, a pair of cross members are pivoted about parallel horizontal fulcrum axes and extend transversely across a boat trailer frame. Each cross member includes a central keel receiver on one side of the associated fulcrum axis. Gimbal arrangements pivotably mount the hull engaging members and establish a first pivot axis parallel to the fulcrum axis, enabling the hull engaging members and keel supports to conform to a variety of boat hull configurations, while maintaining a desired weight distribution proportion between the keel receivers and hull engaging members. The hull engaging members also move about second pivot axes, substantially perpendicular to the fulcrum axes. In a first preferred form, the hull engaging members are elongated bunks mounted to pairs of gimbal mechanisms, a forward pair of which are slotted to permit deflection of the bunks. In another preferred form, hull engaging rollers are mounted at opposed ends of pivoted bars. The bars function as gimbals and are mounted to the cross members for pivotal motion about first pivot axes, spaced adjacent fulcrum axis opposite the keel receiver, and longitudinal second axes to facilitate adjustment and full contact with the boat hull. In another form, hull engaging rollers mount to flexible bunks to receive and deflect responsive to reception of a boat thereon.

Patent CA-2110957-A1 (CA)
Inventor: DE GRANDPRE MAURICE
IPC: A45F5/10
Filed: 1993-12-08
Abstract: Il est à remarquer qu'aucun appareil ne sert à aider la simple personne, à transporter ses sacs de plastics à poignées, lors de ses achats à l'épicerie. La conception même de ces sacs, requière lors du transport, une position repliée de la part des doigts qui doivent par conséquent, supporter tout le poids des marchandises, en plus de subir l'effet de ralentissement sanguin due à la pression exercée par les poignées des sacs. La présente invention découple la tension exercée sur le réseau sanguin par l'intermédiaire d'un crochet qui reçoit les poignées des sacs et qui se trouve supporter par les doigts. De plus, la charge ne se retrouve plus seulement au niveau des doigts et de la main, mais répartie sur les muscles de l'avant-bras parle système de retenue du crochet. Le tout permettant un transport plus équilibré et moins exigeant de la part des doigts de la main et des muscles de l'avant-bras.

Title: Boost pressure control
Inventor: NEUMANN BARRY R
IPC: F02B33/44
Filed: 1992-10-23
Abstract: An apparatus and method for controlling the boost pressure of air delivered to a gas fuelled internal combustion engine (10) from air compression means (32) such as a turbocharger. An engine management system (EMS) (20) controls a spark ignition system (24) as well as a gas delivery system (12) for controlling the delivery of gaseous fuel to a fuel inlet (18). Air is delivered to the engine (10) through air inlet (26) via air throttle means (28) which is also under the control of the EMS (20). Boost pressure is controlled by an exhaust control valve (52) which is operative to direct a proportion of the exhaust gases to turbocharger (32). The amount of compression of the air depends on the proportion of the exhaust gases diverted to the turbocharger (32), which is variable when the engine (10) is operating on gaseous fuel under the control of EMS (20). Pressure and temperature sensor (44) senses the actual boost pressure and provides a feedback signal to EMS  (20) which then compares the actual pressure with a desired boost pressure determined in accordance with at least one operating parameter of the engine (10), such as engine speed and load, and adjusts the condition of control valve (52) accordingly.

Title: Method and Apparatus for Automatically Verifying Faults and Monitoring Chips in a Chip Detection Circuit
Inventor: BITTS DONALD R
IPC: G01M17/00
Filed: 1994-05-27
Abstract: A  chip  detector  is  an  open  circuit  device  that attract metal  chips  circulating throughout a piece of equipment such as a transmission.   If a chip closes the circuit in the chip detector, then it is subjected to a first pulse of energy in an attempt to burn or displace it from the chip detector contacts.   The energy content of  the  first  pulse  is  selected  to  burn  fuzz,  which represents chips  of  an acceptable size.   If the chip remains in the chip detector, then it is subjected to one or more additional pulses each having a greater energy content than the first pulse.   The number of pulses and their energy contents are recorded to determine the size of the chips captured by the chip detector and to provide a history of the equipment being monitored.  If the chip in the chip detector exceeds a predetermined threshold, then an indication is given on a user interface.

Patent CA-2126323-A1 (CA)
Inventor: GELLER WILLIAM L
IPC: H01S3/10
Filed: 1992-12-21
Abstract: A circuit for controlling an extinction ratio of a laser whose temperature can change over time includes first and second feedback loops which monitor a LOW output power of the laser during a first frame training pulse and a HIGH laser output power during a second frame training pulse. The LOW power output is compared to a preset dynamic LOW power reference, and a LOW bias current applied to be laser is incrementally increased or decreased so as to keep this LOW power output toggling about this LOW reference. Similarly, the HIGH power output is compared to a HIGH power reference, and a modulation current for the laser is incrementally increased or decreased to keep the HIGH laser output power toggling about this HIGH reference. Preferably, the training pulse is sent once per frame thus enabling both the LOW and HIGH laser output powers to be kept constant regardless of whatever dynamic variables may change over time thus keeping the laser extinction ratio constant.

IPC: G11B27/32
Filed: 1995-03-27
Abstract: A signal format and reproducing apparatus compatible with that format protect the copyright of recorded video and audio data against digital and analog dubbing. The reproducing apparatus senses copyright information included in the signal reproduced from a record medium to generate a copyright protection signal which is placed in a vertical blanking interval of the analog output of the reproducing apparatus. If a Serial Copy Management System (SCMS) signal is reproduced, it is supplied to a digital VCR. The copyright protection signal disrupts the AGC of a recording analog VCR and the SCMS signal prevents a digital VCR from digitally dubbing the reproduced video and audio data.
