Abstract: A device for picking up animal waste is described that use a waste bag. The pick-up device includes a first concave body and a second concave body that form a waste collection cavity. A hinge along a fixed edge allows a movable edge to move between an open position and a closed position. A spring biases the device into the closed position. An activation mechanism is provided to overcome the biasing force of the spring. Waste bag retainers retainer the waste bag within the waste collection cavity.

Abstract: A waste removal apparatus comprising a handle, housing portion for holding and dispensing bags, and a grabbing assembly actuated by a spring and pulley assembly contained in the handle. Grabbing assembly is further coupled to a first and second frame member wherein the frame members are capable of pivotally attaching to the housing portion. In another embodiment the first and second pivot arms have removable clamps that either secure the frame members for grabbing waste or detach from the frame members making them collapsible. In another embodiment, the housing portion is in the shape of a tube with a roller and also having a slotted groove disposed therein wherein disposable bags may be fitted around the roller and dispensed through the slotted groove. In another embodiment, the grabber assembly engaging the handle is comprised of a button, spring, spring arm with shoulder, and toothed elongated arm engaging the frame members.

Abstract: An apparatus for repositioning bedridden patients with: a base, vertical and horizontal movements, and lifting portion; telescoping legs extending outward from the base with wheels affixed to each leg; detachable clamps affixed to each leg and capable of removeably attaching to a bed; the horizontal movement containing a roller and belts actuated by a gear and crank assembly coupled to the vertical movement portion; the vertical movement having two lifting units with first and second pistons coupled to the inside of each of the units and a hydraulic pump and controller for the actuation of the hydraulic pump and the upward and downward movement of the pistons; the lifting portion comprising a telescoping lifting arm with a lead screw and a crank for extending or retracting said lifting arm and with a lateral movement portion coupled to the top of the vertical movement and the lifting portion.

Abstract: An apparatus is provided for holding a compact disk having a central hole. The apparatus includes a body portion and at least three arms. Each arm extends radially inward from a distal end connected to the body portion to an engageable end receivable within the central hole. Each engageable end has at least one extension member connected to the body portion. Each of the arms has a first pivot axis positioned substantially at the distal end, a second pivot axis positioned substantially at the extension member, and a third pivot axis positioned in between the first and second pivot axes.

Abstract: The invention relates in general to an apparatus for holding a media storage disk. The apparatus comprises a body portion, a central unitary cylindrical hub with a circumference slightly less then the central aperture of the disk, at least one retention finger possessing a retention lip integrated in the outer circumference of the hub, at least one support arm bounding the retention finger to raise the storage media disk away from the disk receiving portion, and at least one ejection arm extending radially from the hub and downward toward the disk receiving portion. When the hub is depressed at least 0.5 mm the retention finger which naturally extends outward from the hub to engage the media storage disk cantilevers inward releasing the disk and the ejection arms are simultaneously pivoted upward to eject the disk in a spring-like manner from the apparatus.

Abstract: The invention relates in general to an apparatus for holding a media storage disk, more particularly an apparatus having an improved central retaining area for the retention of the media storage disk, along with an optional securing means for engaging the media storage disk around its outside circumference. The disk-receiving portion contains a body portion which includes a circular outer retaining wall whose radius is slightly larger than media storage disk. The body portion also incorporates a central retaining area comprising a cylindrical hub, at least one arm extending radially and downward from the hub toward the body portion, and at least one additional arm opposite the first arm creating a hinge between the hub and body portion. Additionally the body portion may incorporate a means to secure the outer diameter of the media storage disk.

Abstract: An apparatus is provided for holding a compact disk having a central hole. The apparatus includes a disk-receiving portion possessing a body portion including a central hub and circular outer retaining wall whose radius is slightly larger than media storage disk. The outer retaining wall in conjunction with the hub and securing means provides for securing the media storage disk within case by overlapping the outer diameter of the media storage disc.

Abstract: An apparatus is provided for holding a compact disk having a central hole. The apparatus includes a body portion and at least three arms. Each arm extends radially inward from a distal end connected to the body portion to an engageable end receivable within the central hole. Each engageable end has at least one extension member connected to the body portion. Each of the arms has a first pivot axis positioned substantially at the distal end, a second pivot axis positioned substantially at the extension member, and a third pivot axis positioned in between the first and second pivot axes.

Abstract: An anchoring device for anchoring an oil well tubing string within an oil well casing. The device generally comprises a drive mandrel and an anchor mandrel. The drive mandrel has an upper end and a lower end, with the upper end releasably securable to an oil well tubing string. The anchor mandrel has an upper end that is releasably securable to the drive mandrel. The anchor mandrel is selectively engagable and disengagable with the interior surface of an oil well casing through the use of a plurality of rotatable slips. The slips have a gripping surface to contact and adhere to the interior surface of the oil well casing such that when the anchor mandrel is rotated in a first direction the slips are rotatably deployed to an engaged position with the gripping surfaces in contact with the interior surface of the oil well casing.

Abstract: A pump rod drive and torque release mechanism for use in association with a downhole pump positioned within a well. The pump rod drive and torque release mechanism comprises a central housing having a generally hollow interior, a drive shaft received within the central housing, a drive rod received within the central housing, and a torque transfer mechanism positioned within the central housing. The drive shaft may be operatively connected to a pump rod rotator to impart rotational movement to the drive shaft. The drive rod may be operatively connected to a downhole pump so as to enable transference of rotational energy from the drive rod to the downhole pump. The torque transfer mechanism has an engaged position wherein it operatively connects the drive shaft to the drive rod such that rotation of the drive shaft causes rotation of the drive rod. The torque transfer mechanism also has a disengaged position wherein it operatively disconnects the drive shaft from the drive rod.

Abstract: A device to be connected to the lower end of a tubing string for removing sand or other debris from oil producing formations below a surface, the device comprising a combination of a thrust and rotational bearing assembly, a rotationally driven downhole pump comprising a rotor and a stator to provide hydraulic energy to lift fluid to the surface, a transfer chamber secured to the pump providing fluid communication between the pump and the tubing string to direct fluid from the pump to enter the string, a nose section secured to the pump rotor and constructed so that sand is mixed with wellbore fluid, a guide to take the mixture to the pump and an anti-rotation device secured to the pump constructed so as to prevent rotation of the pump stator while allowing axial movement of the pump.
