Abstract: A self-cleaning cat litter box apparatus comprises a litter tray for containing a quantity of cat litter, a waste bin, and a mesh basket sized for having lower regions received into the litter. A supporting frame and the basket form a basket assembly that is hinged relative to the litter tray for pivotal movement between a lowered position in which the lower regions of the basket are immersed in cat litter contained in the litter tray and an upright position in which cat waste-containing clumped litter picked up from the tray by the basket is gravity dumped into the waste bin. A basket motor is connected for causing the pivoting of the basket assembly between the lowered and upright positions and for simultaneously opening and closing a waste bin door. Operation of the basket motor is responsive to a cat entering and subsequently leaving the litter tray.

One of the anterior and posterior surfaces is formed having two adjacent peri-axial, stepped imaging zones, the two imaging zones having the substantially the same optical power that is preferably outside the −5 to +5 diopter range.

The transition zone surface may alternatively be continuously curved or variably curved to reduce direct glare and indirect glare, respectively. Attachment members joined to the optic position the intraocular lens in an eye with the optical axis of the optic generally aligned with the optical axis of the eye.

Abstract: A strong, thin flexible mineralized collagen membrane is disclosed that is useful for such medical applications as a barrier for guided tissue regeneration, periodontal defect repair, bone grafts and skin wound repair. The mineralized collagen membrane comprises a substantially homogeneous mineralized collagen composite consisting essentially of about 30% to about 70% by weight of a collagen component and about 30% to about 70% by weight of a calcium phosphate minerals component precipitated from a collagen slurry by a soluble calcium ion-containing solution and a soluble phosphate ion-containing solution.

Abstract: A fluid flow rate control device, especially adapted for controlling the flow of IV fluid to a patient, comprises a first vented fluid chamber having an upper fluid inlet end with a hollow spike which enables fluid connection with a conventional fluid container. A free floating float valve in the first chamber blocks the flow of fluid into the first chamber from the fluid container according to whether or not the fluid level in the first chamber is at a preestablished fluid level, thereby providing a constant pressure head regardless of fluid level in the fluid container. A lower end of the first chamber is connected, through a flow regulator, such as a screw-type valve, to an upper inlet end of a second, vented, drip chamber, the lower end of which is adapted for connection to a discharge tube, such as an IV tube.

Abstract: An orthotic device is disclosed for extending the range of angular movement between adjacent first and second skeletal body parts which are involuntarily held in an angular position relative to one another by contraction of muscles and connective tissue due to immobility. First and second orthotic device portions are interconnected for establishing an initial angle therebetween. The first orthotic device portion is applied to the first body part and the second orthotic device portion is applied to the second body part after the second body part has been pivoted by an externally-applied force to an increased angular position relative to the first body part. A spring connected between the first and second device portions urges the second device portion to return to its initial angular position relative to the first device portion when the second device portion is pulled by the first body part from the increased angular position toward the first angular position of the second body part.
