Title: Pivotable conveyor skirt board assembly
Inventor: OSTMAN ARTHUR C
IPC: B65G21/20
Filed: 2003-10-22
Granted: 2011-11-15
Abstract: A pivotable wall assembly for retaining material on a conveyor belt allows for the wall to be pivoted down for easy access to the inside surface of the wall. Numerous wall assemblies may be attached end to end in individually pivoted back. The easy access makes it quicker and safer to inspect the inside walls to make adjustments, and to remove or replace the liners, the walls and the conveyor idlers. The easy access reduces the man-hours of labor for inspections, adjustments and liner replacements reducing the cost of conveyor maintenance. The modular construction of the pivotable walls allows easy assembly and disassembly. The pivotable walls can be used with hoppers, or other material handling structures. The top and bottom walls have angled portions for engagement with each other to reduce noise, vibrations and dust resulting in less corrosion and wear on the system.

Title: Circuit and method for providing an auto-off capability for a wireless transmitter
Inventor: COHEN ARTHUR L
IPC: H04M1/73
Filed: 2004-01-09
Granted: 2008-12-02
Abstract: The invention is a circuit and method for providing an auto-off capability for a wireless transmitter, of a type having an audio plug which mates with the output jack of an audio source. The portable transmitter modulates audio signals from the audio source onto a carrier and transmits them to a receiver. The auto-off capability is provided to prolong battery life and degradation of the transmitter circuit and comprises pinching off a FET when the circuit is in an "off" state. This occurs when a pre-determined threshold in a capacitor is reached by not discharging that capacitor. The capacitor is discharged by dropping an input to a comparator below a pre- determined threshold limit when presented with an audio peak and wherein the drop in value causes the comparator output to discharge the capacitor and causing the FET to supply power to the regulator.

An intraluminal prosthesis comprising polymeric material is immersed in a mixture of carrier fluid and pharmacological agent(s). The mixture of carrier fluid and pharmacological agent is pressurized for a time sufficient to cause the polymeric material of the intraluminal prosthesis to swell such that the carrier fluid and pharmacological agent at least partially penetrate the swollen polymeric material. Pressure is then removed such that the carrier fluid diffuses out of the swollen polymeric material and such that a predetermined amount of the pharmacological agent remains elutably trapped within the polymeric material.

Abstract: A golf club head is formed of a hollow metal body having a center of gravity that is above the geometric center of the club face. The hollow metal body of the club head has a sole plate that is smoothly contoured and devoid of any inefficient structures such as weight pads or other mass concentrations. By avoiding the use of inefficient structures such as weight pads, more material is available for the structural walls of the club head body while maintaining the club head within acceptable weight limitations. Moreover, placement of the center of gravity above the center line of the face ensures that sufficient backspin will be imparted to the golf ball when struck by the club.

Abstract: The present invention relates to a method and an apparatus for controlling a power-grid connected wind turbine generator during grid faults. During grid faults, the stator windings of the wind turbine generator are disconnected from the power grid and impedances for dissipating at least part of the power generated by the wind turbine during grid fault condition are connected to the stator windings. In this way, a certain magnetisation of the generator can be maintained and after removal of the grid fault condition, the generator is synchronised to the power grid and the impedances are disconnected and the stator windings are reconnected to the power grid. In this way, it is possible to keep the wind turbine generator at least partly magnetised during grid faults and thus ready for delivering power to the power grid, as soon as the grid voltage is re-established after the fault.
