  • Patent number: 5260689
    Abstract: The present invention is a dual-mode alarm apparatus for sports equipment. The two modes of the alarm apparatus are a first motion detect mode and a second separation detect mode. In the first motion detect mode, the alarm can be triggered when the device is moved from a set initial position which could be any orientation. In the second separation detect mode, the alarm can be triggered by the disconnection of a tether cord that changes the position of a tether switch, to help the user to locate his sporting equipment. The alarm fits in a compact housing to fit neatly on the sporting equipment, with an accessible key switch and a flashing LED to indicate the system is armed.

  • Patent number: 5259914
    Abstract: The present invention is a portable vehicle adhesive remover having (a) a motor unit assembled inside a housing including a throttler, a rotor and a gear assembly where the motor unit has an elongated spindle extending out from the top opening of the housing; (b) an extending shank having a proximal end attached to the elongated spindle of the motor unit and a distal end; and (c) an eraser unit attached to the distal end of the extending shank including a resilient eraser member and a disc member embedded in the eraser member. When the eraser unit and the motor unit are attached and a high pressure compressed air is sent into the bottom opening of the housing, the compressed air will be gushed into the rotor by the throttler assembly, which in turn will drive the eraser unit through the gear assembly and cause the resilient eraser member to rotate at a high speed.

  • Patent number: 5257552
    Abstract: Improved handlebars for bicycles, motorcycles, power vehicles such as two wheeled power vehicles and all terrain vehicles, including off road bicycles, motorcycles, dirt bikes, all terrain bicycles, all terrain vehicles and jet skis. The improved handlebars eliminate the need of a crossbar by increasing the diameter and sidewall thickness of the central section of the handlebars, and diminish the stiffness of the handlebars by decreasing the respective diameter and sidewall thickness of the two grip sections of the handlebars. The improved handlebars are incorporated with unique tapered sections and are manufactured through a process that causes greater amount of metal to be located in the widest diameter section of the handlebars, and smaller amount of metal to be located in the narrowest diameter section of the handlebars. The handlebars have a longer unsupported span than conventional handlebars, thereby providing more cushioning strength and greater steering control.

  • Patent number: 5246045
    Abstract: The present invention is an automatic volume fill control apparatus to be used in conjunction with a recovering device which is operable upon being electrically connected to an electrical power source. The automatic control apparatus comprises a control unit electrically interconnected between the electrical power source and the recovering device. The control unit has an electrical circuit which includes an electrical relay switch and connects with a float switch installed in a recovered refrigerant tank. The float switch is normally closed when the refrigerant tank is less than 80% filled, which causes the relay switch to be closed to establish electrical connection between the power source and the recovering device, so the filling of the refrigerant tank continues. When the refrigerant in the tank reaches 80% in volume, the float switch will be opened, which causes the relay switch to open to cut-off the electrical connection between the power source and the recovering device, so the filling process stops.

  • Patent number: 5232062
    Abstract: The present invention is a viscous damping apparatus for damping mechanical shocks discharged on an object. It comprises a container having an inner chamber which has a flat bottom surface, a damping member having a flat lower surface, and means for suspending the damping member such that its flat lower surface is positioned parallel and very close to the flat bottom surface of the inner chamber of the container. The space between the flat lower surface of the damping member and the flat bottom surface of the inner chamber of the container is very narrow and is filled with a body of viscous fluid. When the damping member vibrates and causes its flat lower surface to move toward the flat bottom surface of the inner chamber of the container, the viscous fluid is compressed, which in turn creates an extremely strong resistance force on the damping member that effectively damps the vibration of the damping member.

  • Patent number: 5230596
    Abstract: The present invention is an improved quick release locking nut for quick change type mop holders. The mop holder has a frame attachable to a mop stick and a clamping member for securing mop fill. The quick release locking nut is slidably mounted on a central shank of the frame, and has a pivotally mounted pawl which is biased by a spring. The inner screw threads on the tip of the pawl are engaged with the outer screw threads on the central shank, in order to lock the quick release locking nut on the central shank for preventing the clamping member from sliding on the central shank. When the pawl is pressed against the spring and its tip is disengaged from the central shank, the quick release locking nut is unlocked and can be slid on the central shank for allowing the clamping member to slide on the central shank so that the mop clamp can be released.

  • Patent number: 5221171
    Abstract: The present invention is a non-explosive separation nut for fastening and releasing a threaded bolt under remote control signals. A preferred embodiment of the separation nut includes a housing, a segmented nut, a locking sleeve, a rocker and two non-explosive actuator (NEA) assemblies. The segmented nut can split radially into three or more segments and has an exterior surface with raised ridges and alternate recessed grooves. The locking sleeve is biased by a spring and placed over the segmented nut. It has an interior surface with retaining pins which are engageable with the exterior surface of the segmented nut. The locking sleeve is engaged with the two NEA assemblies through a tiltable rocker. When neither NEA assemblies is actuated, the retaining pins of the locking sleeve are engaged with the ridges of the segmented nut, so that the segments of the segmented nut are compressed radially inwardly for fastening the threaded bolt.
