Abstract: The present invention provides the art of sports bottles with a new and improved air pump, air passage, switch, and optional dispensing tube combination that has particular utility in sports bottle environments as well as other enviroments such as the art of spray bottles, misters, and the like. The present invention further provides a new and improved sports bottle that embodies the new and improved air pump, air passage and switch combination. In operation, the switch activates the pump when the pressure within a liquid reservoir falls below a predetermined pressure thus causing the liquid to flow at a predictable, substantially contant on-demand flow through a conduit operatively connected to the reservoir when a valve disposed in the conduit is actuated by pressure of a user's mouth and/or teeth.

Abstract: The instant invention provides a novel apparatus; a novel method of using the apparatus; and a novel prosthesis made by the method of using the apparatus.

Abstract: The instant invention provides a method and an apparatus for forming a palatal plate prosthesis of a substantially precise, predetermined uniform thickness.

Abstract: The present invention provides an apparatus for cooperating with a powered tool having a work imparting component having a longitudinal axis so as to maintain the longitudinal axis at substantially constant angles in the X-Y, Y-Z and Z-X planes, as defined in part by the X, Y and Z axes while the powered tool is caused to move through a volume of space. The apparatus includes: an adjustable arm having two ends; a clamp arrangement (14-16) for fixing the powered tool to one of the two ends; and, a base (1-2) fixable to a work piece, attached to the other of the two ends, for supporting the adjustable arm (4-13) and the clamp arrangement (14-16). The adjustable arm further includes: a first portion (4, 5) having two ends, for enabling vertical displacement of the longitudinal axis relative to the Y axis; a second portion (7, 9 and 10-13) having two ends, for supporting the clamp arrangement (14-16); and, a third portion (6, 8) for movably fixing one end of the first portion to one end of the second portion.

Abstract: The instant invention teaches a surgical implant wrench that includes: a handle; a head for mechanically engaging the handle at an angle relative thereto, that further includes: finger grip indents disposed thereon; and, a first mechanical assembly for rotatably engaging the crown of a surgical implant that is to be surgically implanted into the boney tissue of a patient. The wrench further includes: a second mechanical assembly for selectively varying the angle; a third mechanical assembly for selectively fixing the angle; and, a fourth mechanical assembly including finger grips for mechanically transmitting rotational mechanical force relative to the axis of the handle, from the handle to the first mechanical assembly.
