Patent number: 4913545Abstract: An adapter for a lens retaining ring and associated indirect ophthalmoscopy lens used by an examiner or practitioner during examination of a patient's eye fundus with a biomicroscope. The adapter includes a body portion for spacing the lens mounted in the retaining ring a predetermined distance from the eye of the patient when the adapter-retaining ring-lens combination is positioned against the eye of the patient under examination. The adapter is adapted to engage the eyelids of the eye under examination, and is so constructed so as to aid in maintaining such eyelids open, and openings are provided in the body of the adapter to aid in preventing fogging of the lens mounted in the lens retaining ring. The adapter may be selectively removable from the associated lens retaining ring (which may be a conventional or known lens retaining ring) or may be integrally formed with the retaining ring.Type: GrantFiled: October 6, 1988Date of Patent: April 3, 1990Inventor: Donald A.

Patent number: 4784348Abstract: A method for manually applying web-like material, such as plastic stretch film in roll form, to packaging units, by winding the web material about the packaging units and controlling the tension and speed of unrolling of the roll of web material while applying the latter to the packaging units, and a simplified tool for accomplishing the method. The tool includes a head and a spindle projecting outwardly therefrom, with the head being adapted to mount a roll of the web material in non-movable relationship with respect to the head. An encircling wrap envelope of the web material is wound about the spindle in relatively rotatable relation therewith, and the tension and speed of unrolling of the web material from the roll while applying the web material to a packaging unit is accomplished by manually squeezing the wrap envelope of material on the spindle, to selectively cause a braking action between the spindle and the envelope.Type: GrantFiled: October 20, 1986Date of Patent: November 15, 1988Inventor: Alex F.

-
Patent number: 4765449Abstract: A press-in reversing knob for a ratchet wrench which has a self-contained retaining means. The reversing knob includes a generally cylindrical member having an annular flange at its upper end and resilient inwardly-deformable projections extending radially outward from its lower end. A cylindrical bore formed in the plug includes a coaxial annular retaining groove spaced downwardly from the top of the bore. As the reversing knob is pressed into the bore, the resilient projection is deformed inwardly by the walls of the bore until the projection engages the retaining groove and springs outwardly. The retaining groove retains the projection to prevent the reversing knob from becoming upwardly disengaged from the bore while accommodating rotational movement of the projection as the reversing knob is turned.Type: GrantFiled: May 6, 1986Date of Patent: August 23, 1988Inventor: Gerald Peters

Patent number: 4754110Abstract: A trigger operated switch assembly for a portable hand tool such as an electric drill that includes a switch casing, housing a switch contact module and a reciprocally movable contact carrier operatively engageable with the switch contact module for controlling communication of electrical energy from a source to an electrical load. An elongated arm extends through an opening in the switch casing and operatively interconnects the movable switch contact module with trigger structure. A seal arrangement prevents or substantially inhibits the entry of foreign material into the switch casing and includes a seal located in wiping relation with the elongated arm and mounted within an opening integrally molded in the switch casing. An additional seal seals a gap between the switch contact module and an inside surface of the casing. An elastomeric cap covers an end opening of the casing and includes apertures through which electrical conductors extend and are connected with the switch contact module.Type: GrantFiled: December 22, 1986Date of Patent: June 28, 1988Assignee: Lucerne Products, Inc.Inventor: Kenneth E.
