The lens support structure includes a base plate which supports one of a pair of the lenses on each side thereof and basket means pivotally connected to the base plate for enclosing the lenses in overlying position and maintaining the lenses on the base plate. A latch structure releasably maintains the basket means in the overlying position, and includes a flexible, integral extension peripherally formed on each basket means and is releasably retained in the overlying position by snap-fit against the hook member laterally projecting from the base plate.

Abstract: A collector unit for collecting tissue or bone from a dental patient during a dental implant procedure generally includes a cover member, a filter support member, a filter medium and a gasket member. The support member is mountable within the cover member with the gasket member positioned therebetween to form the unit. A passage is provided through the unit to allow the passage of fluid material through the unit. The support member has a pair of spaced-apart, opposed filter support arms for removably supporting a substantially flat section of filter medium so that the filter medium overlies the inlet passage such that fluid material passing through the unit must pass through the filter medium which will filter out any bone or tissue specimens. The filter medium is removable from the supporting structure so that it can be positioned in a flat-orientation to facilitate the removal of bone or tissue specimens therefrom. Once removed, the filter medium cannot be reattached to the supporting structure.

Abstract: A fluid pumping assembly for particular use in delivery of sterile fluid used in surgical procedures, includes a pump control structure to which a replaceable fluid pumping cartridge is connected and disconnected to provide convenient replacement and disposability of the cartridge. The pump cartridge is self-contained in that it includes a fluid pump which is adapted for automatic connection to a pump drive structure when the cartridge is inserted into the assembly, so that the sterile fluid is pumped only through the pumping cartridge and fluid flow is entirely isolated from the pump control structure to ensure that the fluid is maintained sterile during pumping. The cartridge can include a selectively activated pulsation control to enable discharging the fluid from the cartridge in either a continuous flow or pulsating flow of the fluid. The cartridge can also include fluid flow dampening and safety vent features.

Preferably, a pair of the flexible extensions are formed as vertically aligned and thinned tabs on opposing edges of each basket, which are snap-fit against a corresponding pair of hooks formed on each side of the lens support structure.

Abstract: A container for storing and dispensing liquid includes a housing having a primary fluid storage cavity for a first liquid, for example, concentrated hydrogen peroxide, and a separate reservoir chamber within the housing so that a second diluent liquid within the reservoir chamber is normally isolated from the primary liquid and storage cavity. An internally movable member within the housing cooperates with the reservoir chamber to form a detent structure which provides selective interference reinforcement to ensure the integrity of sealing between the reservoir chamber and the cavity. The movable member is selectively displaced to relieve the interference reinforcement and sealing and to create a pathway for flow communication from the chamber into the cavity enabling an inter-mixture of the second diluent fluid and the primary fluid.

Abstract: A fluid pumping assembly for particular use in delivery of sterile fluid used in surgical procedures, includes a pump control structure to which a replaceable fluid pumping cartridge is connected and disconnected to provide convenient replacement and disposability of the cartridge. The pump cartridge is self-contained in that it includes a fluid pump which is adapted for automatic connection to a pump drive structure when the cartridge is inserted into the assembly, so that the sterile fluid is pumped only through the pumping cartridge and fluid flow is entirely isolated from the pump control structure to ensure that the fluid is maintained sterile during pumping. The cartridge can include a selectively activated pulsation control to enable discharging the fluid from the cartridge in either a continuous flow or pulsating flow of the fluid.

Abstract: There is disclosed an improved adjusting mechanism for an articulated headlamp construction or the like. The adjusting mechanism is comprised of a minimum number of parts, namely a housing, a scroll member and an adjusting rack member. The scroll member provides the input member for the mechanism and upon rotation thereof rotative movement thereof is transformed into transitory movement of the rack member pursuant to a spiral or scroll projection that is engaged with teeth on the adjusting rack member. The transitory movement of the adjusting rack member will correspondingly produce pivotal movement of the articulated headlamp component. If desired, the adjusting rack member may be curved so that the movement of the end thereof affixed to the headlamp will closely approximate the pivotal movement of the headlamp component.
