Abstract: A dispensing-envelope apparatus consisting of a transparent and hermetically closed drug pocket for small medications or drugs mounted on the front side and lower half of the apparatus. The envelope is designed to pass through a computer-output printer for the reception of printed information or data on the front side and upper half of the apparatus. The printed information is located in an area above the pocket and includes file index information located on the top printed line of the apparatus. The top side of the pocket is closed by a semi-permanent closure with means for easy opening and for reclosing by humans or by machine. When open, the pocket may be filled with drugs by gravity. The drugs in the pocket are dispensed to a patient in accordance with the information provided on the apparatus.

Abstract: A container apparatus for small items such as drug medication. The container is designed for drugs or similar small articles which allows an attendant to dispense the items in accordance with printed or pictorial information provided upon the container or a separate sheet maintained within a pocket of the container.

Abstract: A dental handpiece and a wrench adapted to be used in combination with the handpiece for securing a dental bur in the handpiece. The handpiece includes a turbine housing, a rotor shaft and a collet threadedly secured in the rotor shaft. The wrench has a plurality of fingers which are adapted to be received in the rotor shaft, and a shaft rotatably mounted in a tube from which the fingers project. The wrench shaft is adapted to threadedly advance or retract the collet relative to the rotor shaft.

Abstract: An ophthalmic surgical device including a housing having an extension sleeve projecting from one end thereof. A rotary shaft, having helical threads at one end thereof, which threads terminate in a cutting tip, is disposed within the extension sleeve with the tip being exposed at the free end of the sleeve. The shaft is mounted within three fluid-lubricated sleeve bearings. One of the bearings is mounted within the sleeve adjacent to the tip thereof with its central axis offset and slightly angled with respect to the axes of the other bearings to effect the bending and slight loading of the shaft. The bearings are lubricated by water provided under pressure thereto and serve to enable the shaft to rotate at a high rate of speed under the force provided by an air turbine. Means are provided for supplying a working fluid to the cutting tip of the device to aid in the maceration of the material to be removed by the tool.
