An apparatus, method, and system for automatically turning off an electrically powered actuator in a refrigeration mechanism upon detection of an unwanted condition. In one aspect of the invention, the electrically powered actuator can be the motor of an ice maker / dispenser. The detection can be accomplished by sensing the presence of an object along or near an ice dispensing pathway from the ice maker / dispenser. The unwanted condition could be the presence of the object for more than a preset time period. This would allow to distinguish between an unwanted object such as silverware or clogged ice versus a wanted object such as flowing ice cubes, crushed ice, or shaved ice.

The current invention discloses a water drainage system designed for securing a waterproof membrane as well as centering a wastewater pipe.

The present invention concerns a wind turbine having a plurality of vertically extending airfoils forming a rotating carousel rotating about a central axis thereof. The airfoils pivot about their leading edges to adjust the pitch angle thereof to maximize energy harvest when the airfoils are rotating both in an upwind direction and in a down wind direction. This pivoting movement results from trailing edges of the airfoils being pivotally secured to rigid spokes or cables of a trailing edge hub. An adjustment mechanism is pivotally mounted between a carousel hub and the trailing edge hub and is used to control the separation between a central axis of the trailing edge hub and the axis of rotation of the carousel as they co-rotate. As the carousel rotates, the offset distance between the two axes determines the maximum achievable pitch angle of each airfoil. The airfoils then continually cycle between a positive and negative value of the maximum pitch angle so that each airfoil is at its most desirable pitch angle relative to its position around the carousel and relative to the existing wind direction in order to create maximum lift. A wind direction rudder is secured to the adjustment mechanism to provide for movement thereof resulting in movement of the trailing edge hub as wind direction changes so that the most desirable pitch angle of the airfoils relative to wind direction is maintained.

An articulated cutting head and conveyor mount for sod harvesting machines. The invention provides a linkage design that can provide many benefits including: allowing the operator to see the cutting operation, enabling the high lifting of the cutting head for service and maneuvering, managing the vertical bending load of the ground reference roller, providing high transverse stiffness, maintaining the position of the conveyor relative to the cutting head. The linkage design can include fewer parts than previous designs while still being robust and durable. As such, cutting heads employing the linkage design of the present invention can produce higher quality slabs with less service and maintenance than when using current designs.
