Title: Canal hearing aid with protruding shell portion
Inventor: ARNDT HORST
IPC: H04R25/02
Filed: 1994-08-17
Granted: 1997-12-09
Abstract: An in-the-canal hearing aid has a shell having an inner end to be positioned in the canal adjacent the user's eardrum, and a faceplate located outwardly of the inner end but still adapted to be recessed within the ear canal in use.  A protruding portion of the shell extends outwardly past the faceplate into the concha bowl and serves the dual purpose of both anchoring the hearing aid in the ear so that it cannot work its way down the ear canal, and providing a grip to facilitate insertion and removal of the hearing aid.   The protruding portion is preferably cut back close to the faceplate at one side of the faceplate to facilitate battery insertion and removal, and may contain an aperture or a hook-like portion to facilitate gripping.  A vent to vent the hearing aid may extend outwardly on the protruding portion to a position adjacent the rim of the protruding portion, to space the outer vent opening away from the microphone opening on the faceplate, to reduce the likelihood of feedback.

Title: Method of manufacturing injection molding manifold having a melt passage with an elbow
Inventor: GELLERT JOBST ULRICH
IPC: B23K1/00
Filed: 1994-12-16
Granted: 2005-02-22
Abstract: A method of making an injection molding melt distribution manifold wherein the melt passage branches through a number of elbows leading to different gates.      Each elbow is preformed in a cylindrical plug which fits in a bore in an outer end of the manifold in alignment with a lateral portion of the melt channel. A brazing hole with an upward mouth is drilled in the outer surface of the plug and nickel alloy brazing powder is poured into it. After insertion into the bore in the manifold, the plug is rotated with a suitable tool to a predetermined position with the mouth of the brazing hole pointed downward. The manifold is then heated in a vacuum furnace to integrally braze the plugs in place simultaneously with brazing an electrical heating element in a channel in the manifold.      The melt passage is then completed by drilling an outlet bore from the front face of the manifold to the outlet of each elbow.
