Patent CA-2808003-A1 (CA)
Inventor: LOUCKS J NATHAN
IPC: B25B11/00
Filed: 2013-03-14
Abstract: A splitting tool and upright device, used together to split kindling from pieces of firewood. The splitting tool has a steel dowel that protrudes through at the cutting end perpendicular to the blade. The upright device is fastened to a base and consists of identical parallel plates, having a series of matching, downward-facing notches. Firewood is placed on the base adjacent to the upright device. The dowel end of the splitting tool is placed between the parallel plates of the upright device just above the wood. Downward force is applied to the handle of the splitting tool. The dowel braces in the notches and becomes a fulcrum. Leverage amplifies the force and causes the firewood to split. As the handle of the splitting tool is raised, the dowel slides down to the next pair of matching notches. This controlled process is repeated until the kindling is split.

Abstract: The present invention relates to a heat recovery system, of a part of the energy spent in the preparation of waste water, e.g. water from baths or kitchens, energy that is usually lost when the water is drained into the sewer. This energy can be recovered and reused to heat water that is readily used, for example in the shower, or can be stored in a water heater. This system is designed in such a way that, together with any tub or shower base, constitutes a heat recovery shower base or a heat recovery bath, for example. The energy recovery system is composed, preferably, by a coil generally made of copper inside a PVC pipe that has at one end a throttle plate also made of PVC, a filter for the protection of the system against impurities, turbulence fins, and an external casing. The system has a compact structure which benefits its rapid adaptation.

IPC: F03B17/04

Abstract: A mechanism 1 transfers a fluid between vessels in closed circuit communication, the variable volume vessels 4e, 4c being in fluid communication. Preferably the mechanism is a rotating mechanism and the vessels are hinged to an arm 2 pivoted to a support 12. In a stop/start position AP of the arm, the highest vessels 4e is in expanded condition and causes rotation of the arm 2 due to gravity until the vessels find themselves in reversed positions, with the expanded vessel 4e down and the compressed vessel 4c up. Expansion/compression means 8 act on the vessels as a consequence of gravity effect, thus causing the fluid to shift from the lowermost vessel to the uppermost vessel. The fluid transfer leads to the restoring of the initial condition and to a new rotation of the arm and vessels, bringing the expanded vessel downwards and the compressed vessel upwards. The vessels oscillate to help the arm rotation. In a further embodiment, the vessels move toward and away from the rotation axis of the arm, to increase the momentum. The fluid is thus transferred from one vessel to another without the need of any action from an operator.

Title: Reduction of altitude error using forecasted atmospheric pressure data
Inventor: GARCIA MICHAEL A
IPC: G01C25/00
Filed: 2014-03-10
Abstract: A technique for reducing altitude error involves determining a corrected altitude for an aircraft using forecast atmospheric pressure data available, for example, from a weather forecasting service. The forecast atmospheric pressure data includes, for a number of points in time and for a number of geographic locations, a set of pressure levels and corresponding altitude values. Altitude correction data is periodically calculated from the forecast atmospheric pressure data for each of a number of geographic grid points. Upon receiving aircraft position information and an aircraft altitude measurement for an aircraft, one or more of the geographic grid points corresponding to the aircraft position are identified, and a corrected altitude of the aircraft is determined based on the altitude correction data of the one or more geographic grid points.
