Abstract: To dispose wine expectorant from a spit bucket, the interior of a portable pressurizable rigid tank is connected to a vacuum pump which draws a vacuum in the tank. The tank is disconnected from the pump and transported to the spit bucket. An inlet end of a suction conduit connected to the tank is inserted into the spit bucket. A passage from the inlet end to the tank interior is opened to cause the vacuum in the tank to draw-in the wine expectorant from the spit bucket. The tank is taken to a discharge station, and a drain of the tank is opened in order to discharge the tank contents.

Abstract: To chill an alcoholic beverage, the beverage is poured into at least one shotglass which is then lidded to form an air-tight seal. The lidded shotglass is inserted into a refrigeration compartment, whereby the alcoholic beverage is chilled to a temperature at or below 0° F. The lidded shotglass is removed from the refrigeration compartment when it is desired to consume the alcoholic beverage, and the chilled alcoholic beverage is drunk directly from the shotglass after removing the lid. A number of the lidded shotglasses can be placed in a thermally insulative container, whereafter the container is placed in the refrigeration compartment to chill the alcohol.

Abstract: A dental prophy cup includes a polishing surface formed by a plurality of annular ridges spaced along a longitudinal axis of rotation of the prophy cup. Each ridge includes a generally forwardly facing side which has a micro-cellular texturing capable of retaining abrasive paste. The cup is molded of a solid elastomeric material in a mold which forms the micro-cellular texturing on the polishing surface.

Abstract: A dental prophy cup comprises a flexible body having a cavity formed therein. A rear end of the cavity includes a paste reservoir for storing an abrasive paste. Paste-delivery channels extend forwardly from the reservoir and intersect front and rear circumferentially extending paste-distribution channels. Under the action of centrifugal force occurring during a tooth-cleaning procedure, paste is fed forwardly along the delivery channels and is distributed within the distribution channels. Between the channels is disposed a pattern of ridges which are capable of flexing relative to one another to conform to the shape of a tooth surface.

Abstract: A dental prophy cup includes an elastically flexible rim which includes a flexure region of reduced thickness. The rim thickness increases to a region of maximum thickness at a location forwardly of the flexure region and then tapers downwardly toward a front end of the rim. A forwardly facing surface of the cup which contacts the tooth surface comprises two convex surface portions joined by a radiused bridge surface portion located at the flexure region. Abrasive particles are distributed within the body of the cup and are released as the base material of the cup breaks down.

Abstract: A dental handpiece for rotating a dental cleaning tool includes a casing in which there is mounted a drive shaft that is operably connected to the cleaning tool. A rotor is affixed to the drive shaft and is driven by compressed air fed to the casing. The drive shaft is hollow and communicates with a reservoir situated within the casing. The reservoir contains a refillable supply of dental paste. Pressurized air is fed to the reservoir to push paste through the hollow drive shaft and into the dental cleaning tool. The interior of the drive shaft includes a helical screw which aids in feeding the paste toward the cleaning tool.

Abstract: A sheet-feed tractor of the type that includes a belt with pins for advancing edge-perforated paper is provided with an extension on its web-retention door for mounting an idler roller that is used for friction feed of paper that does not have edge perforations. A drive roller is provided opposite the idler roller on a drive shaft that also is used to drive the belt containing the pins. As a consequence, paper located between the drive and idler rollers is advanced when the drive shaft is rotated.

Abstract: A harness for connecting the inputs of an EKG machine or the like to electrodes attached to the body of a patient in which the series resistance required to protect the machine from the presence of high energy pulses applied to the body by a defibrillator is provided by the distributed resistance of shielded conductive carbon loaded polymer leads. Both shields and leads are respectively connected to connectors of a yoke to which EKG leads may be attached.
