Abstract: The present invention relates to a portable, self powered, oral cavity cleaner that produces a pulsed stream of fluid to clean the teeth, and areas around the gums and teeth. It is powered by compressed gas contained in a container along with the fluid to be dispensed, and has a valve that produces a pulsed stream.The fluid in the pressurized unit could contain some or all of the following: breath freshener, plaque inhibitor or dissolving agent, bactericidal and bacteriostatic ingredients. It should also exhibit the ability to be swallowed so that spitting it out might be obviated while leaving the mouth feeling refreshed.The stream is directed by a tube that has an angle and an articulated joint that is leak proof and snaps together for assembly. The dispensing tube, articulated joint, and pulsating valve are protected by a hygienic cover which rotates respective to the container to expose the tube. The pulsating valve, hygienic cover and dispensing tube may be reused.

Abstract: A sealing device for a liquid applicator of the type having a liquid applicator tip, with open and sealed positions. The end of the applicator through which the tip extends is petallate, with the petals sloped toward each other to define a circular opening at their distal ends. The petals are enclosed with a highly resilient member of generally truncated conical shape having an integral end portion which covers the circular opening. In the sealed position, the end portion defines a closed elongate channel along the longitudinal axis of the applicator, hermetically sealing the tip within the applicator and sealing around any debris that may be within the channel. In the open position, the end portion defines an open elongate channel, resulting from a shoulder associated with the tip forcing the ends of the petals outward to stretch the end portion of the resilient member as the tip is moved to the open position, thereby to open the closed channel, without the tip contacting the end portion.

Abstract: In one embodiment, there is provided an axial nut starter having a nut engaging member which can be used with a wide range of nut sizes. The nut engaging member is in the form of a stepped series of stacked, coaxially aligned cylinders. The base, or the largest cylinder, of the nut engaging member is attached to an elongated handle. The top, or the smallest cylinder, of the cone is inserted into the nut until the wall of one of the cylinders frictionally engages the threads of the nut and the face of the nut shoulders against the top of the next larger cylinder. Unitary rotational movement of the handle and the nut engaging member starts the nut on the fastener. In another embodiment, an offset nut starter is provided which permits the starting of a nut on a fastener when it is impossible to reach the fastener along its axis.

Abstract: A combination jaw rest and ejector having a generally hollow wedge-shaped body with upper and lower channels in which a patient's teeth rest and which holds open the patient's mouth. The wedge-shaped body is placed in the patient's mouth on the side opposite that on which work is being performed. A suction hose is attached to the body and the side of the body facing the work site is perforated so that a relatively high volume of air may be drawn into the body through the suction hose, thus drawing, with the air, blood, spray, and debris and substantially preventing the discharge of these materials, which may carry disease transmitting factors, from the patient's mouth. In one embodiment, the body includes perforated salive collecting tube and/or a tongue depressor attached thereto. In a further embodiment, the body includes an illumination source therein to illuminate the interior of the patient's mouth.

Abstract: A shield for a paint roller is adapted for washing a paint roller while the roller is mounted within the shield. The paint shield includes a splash guard that when not being used for washing, is rotated into a splatter guard. When the roller is to be washed, the spray shield is rotated to cover the opening defined by the splatter guard. The spray shield has openings defined therein so that wash water may drain therethrough while through which little or no watery paint spray may pass. A water hose is attached to the splatter guard which supplies water to a chamber which includes a slot extending the length of the roller and which includes holes positioned to direct sprays of water at the roller bearings. In a preferred embodiment, a second chamber is provided to have liquid soap placed therein which mixes with the water to aid in cleaning the roller.
