US Patent:

53741366, Dec 20, 1994

Filed:

Apr 6, 1994

Appl. No.:

8/224101

Inventors:

Pierre LaPlante - Newberg OR

Assignee:

A-Dec. Inc. - Newberg OR

International Classification:

F16B 100

US Classification:

403370

Abstract:

The bracket (12) is bolted loosely to the attachment arm (14) of a dental chair to establish a preliminary orientation of the bracket relative to the attachment arm. The bracket is then levelled with adjustment screws (40) which bear against a surface on the attachment arm to establish a level orientation. The bolt fastening the bracket to the attachment arm is then tightened to fix the level orientation.

Filed:

Mar 2, 1989

Appl. No.:

7/318823

Inventors:

Pierre LaPlante - Newberg OR

Assignee:

A-Dec, Inc. - Newberg OR

International Classification:

A61C 1702

US Classification:

433 82

Abstract:

An extruded conduit structure for conveying several different fluids is provided comprising a cluster of at least three tubes connected by webs extending between adjacent pairs, the tubes and webs being formed by simultaneous extrusion of a suitable plastic through a suitable die. The outer surface of each of the webs is convexly curved in an arc that is substantially tangential with the outer surfaces of the adjacent pair of tubes. The inner surface of each of the webs is flat relative to the outer surface and forms a cord of such arc whereby each of the webs will be of minimum thickness along each of its junctures with the adjacent webs. This construction substantially eliminates any concave surfaces on the exterior of the conduit within which foreign matter may collect and, because of the thinner wall sections at the juncture of the webs with the adjacent tubes, the webs can be easily stripped along the tubes to expose the tube ends for connection to the appartus, such as a dental handpiece to which they are to be connected.

International Classification:

F16J 1532

US Classification:

277 12

Abstract:

The seal (10) comprises a one-piece molded cylindrical body having an open end (12), a closed end (16) , and a cylindrical side wall (14). Outwardly projecting sealing ridges (26 and 18) are formed on the wall portion. Seal 10 is inserted into a bore (38) in a control panel (40) such that the sealing ridges contact the bore to seal out moisture, chemicals and other contaminants, and to retain the seal in the bore against upwardly directed pressure.

Appl. No.:

7/362228

Inventors:

Pierre LaPlante - Newberg OR

International Classification:

F16L 3500

US Classification:

285 26

Abstract:

An in-line quick connect multiple port fluid coupler is disclosed. The coupler has two identical coupling units. Each coupling unit has a body and an integral tongue. The tongue has a face which is perpendicular to the longitudinal axis of the coupling unit. Fluid passages interconnect the body and the face of the tongue. Each coupling unit mates in a face-to-face relationship with the other coupling unit. Guide pins and seals are used to provide a fluid tight passage between the fluid passages and each opposing face. A sleeve circumscribes the mated coupling units to ensure a secure assembly.
