Appl. No.:

6/338231

Inventors:

Richard M. Hunt - Indianapolis IN

Assignee:

Bell Telephone Laboratories, Incorporated - Murray Hill NJ

International Classification:

H04R 1100

US Classification:

179115R

Abstract:

An electromagnetic transducer is disclosed that includes a pole assembly (110) comprising a central pole piece (112) upstanding from a back plate (114). A coil assembly (120) is disposed about the central pole piece (112) and rests on the back plate (114). In addition, an inverted cup-shaped permanent magnet (130) having a central opening (132) in its base (131) is positioned so that the wall (134) of the magnet circumscribes the coil assembly (120) and rests on the back plate (114). The rim of the central opening (132) in the base (131) of the permanent magnet (130) is spaced from and encircles the upper end of the central pole piece (112). Also the wall (134) of the permanent magnet (130) is of a height that the upper surface of the base (131) lies in essentially the same plane as the upper surface of the pole piece (112). A central armature (222) is supported by a nonmagnetic diaphragm (221) so as to be positioned above and spaced from the central pole piece (112). The armature (222) lies in a plane that is essentially parallel to the plane of the upper surface of the pole piece (112), and the armature is of a size that it overlaps the portion of the base (131) of the permanent magnet (130) immediately adjacent to the central opening (132).

International Classification:

H04R 900

US Classification:

179120

Abstract:

The disclosure relates to a ring armature electroacoustic transducer adapted for use as the receiver for telephone sets and for other purposes. The exemplary embodiment comprises the following elements coaxial about a common vertical axis: (a) a cylindrical ring permanent magnet (15) of Fe-Cr-Co material, (b) an annular disc upper pole piece (20) seated on magnet 15 and having at its inner margin a downwardly salient annular boss (30) providing an upper pole tip, (c) a lower pole piece (35) providing an annular lower pole tip (37) and aflange (36) coupling such tip (37) to the bottom of the magnet, (d) an armature support (40) within the magnet (15), (e) an annular disc armature (50) seated on the support (40), (f) a diaphragm (60) on the armature (50), and (g) a terminal plate (45) supporting such elements. The armature (50) is seated on a circular edge (90) on the support (40). The support (40), lower pole piece (35) and plate (45) form a unitary structure.

International Classification:

A61B 17/80

Abstract:

A bone plate system includes, for example, a bone plate and at least one bone plate hole cap. The bone plate includes a body having a first surface, a bone-engaging surface, and a plurality of through-openings. The bone plate hole cap includes a body having a first surface, a second surface, and a peripheral surface. The bone plate hole cap is securable in at least one of the through-openings in the bone plate. When the bone plate hole cap is secured in the through opening, the second surface of the bone plate hole cap is disposed adjacent to the bone-engaging surface of the bone plate. The bone plate with the bone plate hole cap secured in the through-hole increases the bending strength of a portion of the bone plate across the bone plate hole cap compared to the portion of the bone plate without the bone plate hole cap.

Abstract:

The present disclosure relates to a tibial osteotomy system. The system includes a base plate configured to interface with the tibia which includes a body with a first pair of apertures configured to receive a first pair of stabilization elements, a first end with a first aperture, and a second end with a second aperture. The system also includes a measuring arm coupled with the first end of the base plate via the first aperture and having a third aperture aligned with the first aperture to receive a first screw, and a cut guide pivotably coupled with the second end of the base plate via the second aperture and having a fourth aperture aligned with the second aperture to receive a second screw therein. The cut guide also has a slot, a measurement flag releasably couplable within the slot, and a protrusion configured to receive a second stabilization element.
