Filed: 1990-09-26
Abstract: PC(HO) 7655 ABSTRACT A prosthetic part for use as an orthopaedic implant has a cast metal base member      and a tissue ingrowth surface spaced outwardly therefrom.   The tissue ingrowth surface is in the form of a cast metal lattice element which covers at least a part of the outer surface of the base member    .    The cast metal lattice element     is cast simultaneously and integrally with the base member from the same metal.   This metal may be any well known castable  material  for  ortho-paedic  implants  such  as Vitallium or titanium.  The lattice element     is in the form of a grid-like mesh which includes spacer members cast integrally with the wire mesh and the base member to space the lattice element      a predetermined distance above the prosthesis surface.       An investment casting technique wherein a meltable material is coated with a ceramic casting shell is utilized to produce the integrally cast orthopaedic implant and tissue ingrowth surface.

Abstract: Form 24                     Sheet 2 of 5 ABSTRACT          The  primary  function of this invention is to provide the  driver with  unobstructed  120  degree  rear  view  visability,   thereby virtually eliminating the normal rear view mirror blind spots  and the  need  for  projections  of side mirrors which  in  turn  will provide a sleeker looking automobile.  Passengers in the back seat can, at times, obstruct the traditional rear view mirror. Frost on the window,  that takes time to clear, also obstructs rear viewing for the initial period of driving time in northern climates during the  winter.   This  one  mirror  replacement  system  may  reduce manufacturing  costs by reducing the number of  mirror  enclosures and parts.

Title: Bottle neck having means to prevent compression of cap skirt
Inventor: REPP RICHARD E
IPC: B65D41/48
Filed: 1991-07-25
Abstract: ABSTRACT            Container neck finishes produced by preforming processes such as injection or compression molding can generally be made to more accurate dimensions than blow molded finishes.  Blow molded bottles conventionally have had an outward slanted area below the locking beads which merges into a horizontal shoulder on which the lower edge  of  the  cap  skirt rests,  the  slanted  areas preventing the lower portion of the skirt from being compressed or pinched-in.   As a substitute for the slanted area of blow molded bottles,  the present invention provides annular rings on a preformed finish which supports the skirt against compression and a larger diameter second annular ring which functions as a shoulder on which the lower edge of the cap skirt may rest.

Title: Arc suppressing interrupter
Inventor: TORRES-ISEA RAMON O
IPC: H01H9/32
Filed: 1991-09-11
Abstract: ?C-109 ABSTRACT OF THE DISCLOSURE          A current interrupter in which a first movable, insulating, gear carries a contact blade.  The blade extends out from this movable gear and forms a contact which makes and breaks with a stationary contact upon movement of the gear. A second insulating gear has a set of teeth which engage the teeth on the first gear.  The second gear has a cavity into which the extended contact fits. Movement of the first gear in a direction to break the contact, causes the engaged teeth to drive the extended contact into the cavity, thereby insulating the movable contact from the stationary contact. The interlocking gear teeth create a tortuous path for the arc and provide a large over surface distance for dielectric strength.
