Dentsply Research Development Corp. - Milford DE
International Classification:
A61C 1702
US Classification:
433 86, 433119
Abstract:
The invention provides a method of making a transducer activated tool tip, comprising, providing a substantially linear tip body having a fluid inlet end and a fluid outlet end. The tip body has an inlet end and a subgingival outlet end. The tip body is bent in a first direction. In the tip body is formed a fluid passageway internal to the tip. The tip body is bent in a second direction, which is opposite to the first direction.
Elapsed Time Indicator
US Patent:
4207733, Jun 17, 1980
Filed:
Sep 7, 1978
Appl. No.:
5/940479
Inventors:
Leonard H. Copeland - York PA
Joseph B. Wible - Lancaster PA
Joseph B. Wible - Lancaster PA
Assignee:
Datcon Instrument Company - East Petersburg PA
International Classification:
G04F 800, G04B 1500, G04B 1902
US Classification:
368108
Abstract:
An elapsed time indicator is provided which performs accurate and reliable time measurements. The device includes an indicator assembly having a plurality of numbered wheels drivingly coupled to a drive wheel having a plurality of upstanding peripheral teeth. A verge escapement mechanism employs a side acting verge member which moves in a predetermined plane and acts on only one side of the drive wheel. The peripheral teeth of the drive wheel cooperate with the verge member to move the drive wheel through predetermined intervals and drive the numbered wheels of the indicator assembly. An electromagnet pulsed by a solid state time base and driver circuit oscillates the verge member to advance the drive wheel and to operate the indicator assembly.
Fog-Resistant Gauge
US Patent:
4628731, Dec 16, 1986
Filed:
Jan 13, 1986
Appl. No.:
6/818593
Inventors:
Leonard H. Copeland - York PA
Assignee:
Datcon Instrument Company - East Petersburg PA
International Classification:
G01D 1124, G01D 1126
US Classification:
73431
Abstract:
An improved gauge design is presented wherein the tendency of fogging of the lenses is eliminated or reduced. The gauge of this invention includes an inner lens spaced between the dial and outer lens and a surronding baffle which is disposed between the lens and the inner surface of the gauge case. The baffle restricts air flow into and out of the space between the two lenses. In addition, both the inner and outer lens preferably are coated with a clear anti-fog coating. Finally, the port in the gauge within which the needle is mounted is surrounded with a sleeve to further restrict air flow.
