Abstract: A lure has an elongated plate form body with a generally concave inner face and generally convex outer face. A hooked member is attached near the rear end of the body. A cross-wise bend close to the rear end of the body defines a linearly profiled head section and a linearly profiled tail section. The tail section is significantly shorter than the head section, and the tail section is inclined inward at an acute angle, typically between 25-45 degrees, relative to the head section. The relative lengths and inclination of the two sections of the lure induce simultaneous flutter and kicking as the lure is pulled at its forward end through water. The lure may be formed of a resilient metal that permits some manual adjustment of the angle of inclination. The angle can be increased to preserve flutter and kick at slower trolling speeds or reduced to avoid spinning at higher trolling speeds.

Title: Thermal barrier for use on the front flange of a mullion in a curtain wall
Inventor: LABRECQUE NORMAND
IPC: E04B2/96
Filed: 1998-10-22
Granted: 2000-06-06
Abstract: The thermal barrier is used on a flange projecting out from the front portion of a mullion in a curtain wall. The curtain wall comprises horizontal and vertical mullions defining a plurality of subsections, each enclosing a windowpane. This thermal barrier comprises a front section and two side sections transversally projecting from opposite edges of the front section. The front and side sections define a flange-receiving housing. The thermal barrier is shaped and sized so th at a rear edge of at least one side section is in a positive engagement with the fr ont portion of the mullion when the thermal barrier is installed over its flange. Th is thermal barrier replaces the conventional thermal barrier without changing the structural resistance of the curtain wall. It provides an improved thermal insul ation and corner plugs are no longer necessary to fill the spaces between perpendicula r flanges. Smaller amounts of caulking are also required to seal the space created by the expansion joint between two vertical mullions since that space is much smaller than the one left by conventional thermal barriers. The installation of the curtain wall is thus simplified and more rapidly completed. The quality of the w ork is also likely to be more constant. A further advantage is that each thermal bar rier entirely covers the flange so that a windowpane, during its installation in a subsection, is less likely to be damaged since the edges thereof never directly make contact with the hard aluminum interior surface of the flanges.

Abstract: A dynamic method for optimizing interference levels between multiple downlink beams transmitted from a satellite with a common frequency spectrum causes the power level of at least one of the interfering beams to be adjusted so as to produce desired interference levels within the beams' respective ground target areas. The beam power adjustments are preferably accomplished by varying the drive levels of the high power amplifiers on board the satellite, at least one of which is initially operated at less than its maximum rated power level. Single or multiple beam powers can be adjusted, either up, down or some up and some down. Power level adjustments are normally made in response to actual beam power profiles not matching design standards, to changing service priorities among the different beam target areas, and to changing signal power requirements for the different beams.

Granted: 2005-12-06
Abstract: A headlands control system for a winged agricultural implement includes a headlands actuator operatively connected between implement wing actuators for establishing operation in either of two modes. In the first mode, when the headland actuator is in a first position (e.g.extended), the wing actuators are provided extra downward range to pivot and bias the wing sections downward below horizontal as may occur during operation over uneven ground. In the second mode, when the headland actuator is in a second position (e.g. retracted) and the implement is raised (e.g. at the headlands), the downward range of the implement wings is more limited (as compared with the first mode) at the point where the wing actuators are fully extended. This system thus provides means for preventing implement wings from drooping in the headland position so the operator is not required to reset the wing control from float mode, or from down pressure mode, depending on what is equipped.
