Title: Interlock circuit for a lawn and garden tractor
Inventor: HOUGH BARRY MICHAEL
IPC: B60K25/00
Filed: 2001-03-30
Abstract: An interlock system for a lawn and garden tractor or similar vehicle includes a latching circuit with a two-pole seat switch and an operator push button switch connected to a latch relay to provide operator actuated mow in reverse feature. The system provides a latching function which is actuated by the operator each time the vehicle is put into reverse to facilitate mowing in reverse. If the vehicle is placed in reverse with the PTO turned on and without the push button switch being depressed, the engine will be disabled. Also, if the operator leaves the seat while the vehicle is mowing in reverse, the engine will be disabled. The circuit includes a two pole operator presence switch connected to the PTO  switch and to the brake switch, respectively, to isolate the circuits for simplicity and ease of routing connecting lines to indicators.

Title: Starch ester
Inventor: TANAKA HIDEYUKI
IPC: C08L101/16
Filed: 1999-11-10
Abstract: The present invention relates to a starch ester having short- and long-chain acyl groups wherein hydrogens in reactive hydroxyl groups in the same starch molecule have been replaced by C2-4 short-chain acyl groups and C6-18 long-chain acyl groups.      The degree of substitution by the short- and long-chain acyl groups are regulated so as to make the starch ester thermo-plasticized and moldable even in the absence of a plasticizer. Accordingly, the starch ester of the present invention can be used as a biodegradable thermoplastic plastic material which can be thermo-plasticized in the absence of a plasticizer.

Title: Utility lighter
Inventor: TUBBY BRIAN
IPC: F23Q2/36
Filed: 2000-02-29
Abstract: The present invention relates to a utility lighter (10) including a housing (12) having a handle (14), a nozzle (18) with an outlet (64), and a fuel supply (22). An electric ignitor assembly (34) is connected to a first electrical pathway (P1) and a second electrical pathway (P2). The first electrical pathway includes a first gap (62) proximate the outlet. The second electrical pathway has operative and inoperative ocnfigurations. In the inoperative configuration, the resistance of the second electrical pathway is less than the resistance of the first electrical pathway such that electrical current generated by the electric ignitor assembly selectively travels in the second electrical pathway. In the operative configuration, the resistance of the second electrical pathway is greater than the resistance of the first electrical pathway such that the electrical current selectively travels in the first electrical pathway and jumps across the first gap to form a spark to ignite fuel from the fuel supply.

Patent CA-2377918-A1 (CA)
Inventor: GOLD BRUCE G
IPC: A61K31/365
Filed: 2000-07-07
Abstract: Neurite outgrowth and nerve regeneration are promoted by disruption of the steroid receptor complex and stimulation of MAP kinase/kinase activity. This disruption can take the form of disruption of the physical assembly or function of the steroid receptor complex, such as the mature complex or a precursor of the mature complex that is required for assembly of the mature complex. Geldanamycin and its analogs, bastadin and members of the bastadin family, and radicicol and its analogs, as well as FKBP-52 antibody, are shown to disrupt the complex and promote nerve growth. Assays for finding neurotrophic compounds, as well as compounds found by these assays, pharmaceutical compositions into which they are incorporated, and methods of treating subjects having neuronal dysfunction caused by injury or desease are disclosed. Any of these compounds can be used in combination with a therapeutically effective amount of heat, such as heat applied locally to an area where nerve growth is desired, or systemically in an organism in which neurite growth is desired. Alternatively, these compounds can be used in association with a template, such as a tubular member that defines an anatomic pathway along which nerve regeneration is desired (particularly around transected or partially transected nerve).
