A movable barrier operator having improved safety and energy efficiency features automatically detects line voltage frequency and uses that information to set a worklight shut-off time. The operator automatically detects the type of door (single panel or segmented) and uses that information to set a maximum speed of door travel. The operator moves the door with a linearly variable speed from start of travel to stop for smooth and quiet performance. The operator provides for full door closure by ...

A moveable enclosure for use in applying a sprayed material on the surface over which the enclosure is moved includes a frame assembly defining a plurality of side walls with roller means for movably supporting the frame. A mesh skirt is supported by the frame adjacent the plurality of side walls and is positioned with its lower edge adjacent the surface. A mesh top canopy is positioned on the top of the frame with its lower edge overlying the upper portion of the skirt to complete the enclosure...

A device for animating a steer for use in the practice of roping a steer. The device has a pedestal member and a guide arm rotatably secured to the pedestal member. A frame is connected to the guide arm and is for supporting a motor for driving the frame. A surface engaging member is mounted to the frame and is adapted to effect movement of the frame along an operating surface. The motor is mounted to the frame and is operative coupled to the surface engaging member for driving the same. A first...

An open-top container or skid having a base, two spaced and parallel sidewalls, and at least one sidewall which is moveable between an upstanding position and a stored position, with the stored position being a position wherein said moveable sidewall lies flat against the base.

A seat mounting that allows omnidirectional movement of the seat in a single plane by means of two pairs of sliding rods, one pair perpendicular to the other, and a rotatable disc. Rods are locked and released by a series of skewed locker-like pieces that may be moved by a cam mechanism. The rotational disc is locked and released by a pin that extends through the disc into an underlying hole. Locking and release mechanisms are controlled by a single cable.

An efficient economical process is provided to produce an intricate impressive display with outstanding marketing and advertising appeal. In the process, multiple images are formed, such as on a central processing unit, the images are masked and striped, and portions thereof are superimposed. The superimposed masked images can be printed on an underlying back web. Transparent rods, a plate lens, a cluster of anamorphic lenses, or a grid, can be placed in front of the back web to provide a specia...

A tower is located within a tube and is arranged to displace a liquid, which preferably is water. The tower may be arranged to float in the water and its buoyancy is controlled to cause movement of the tower relative to the tube. An observation gallery may be is carried at the top of the tower for carrying passengers, being arranged to rotate relative to the tower. As the tower floats in water, and the volume of tower structure which moves out of the water is minimal, the amount of energy requir...

A moveable radiator grille assembly for an automotive vehicle includes a grille, a bracket member connected to the grille for supporting the grille, support assemblies interconnecting the grille and vehicle structure for allowing movement of the grille relative to vehicle structure.

A support for the wrists and forearms of a user performing manual tasks, such as operating a keyboard, assembling small parts and the like, includes a rectangular flat work-supporting frame and a pair of arms pivotally mounted on the frame. An elongated cushioned forearm and wrist support is mounted on the outer end of each arm to support the user's forearms and wrists so that the fingers can be used to perform a manual task.

A dispenser for flowable materials such as liquids includes a pair of stationary plates, with a movable plate therebetween. Pumps are mounted between the movable plate and at least one of the stationary plates. A drive system moves the middle plate toward and away from the stationary plates to provide a pumping action. The pumps are mounted to a stationary plate with an adapter, which extends through the plate. A valve assembly is mounted on the reverse side of the stationary plate in registry w...
