Abstract: A method for making an acetabular reamer for an acetabular reamer comprising the steps of: fabricating a bowl shaped cup-blank having outer and inner bowl shaped surfaces, perforating a plurality of holes through the cup-blank, the holes each are surrounded by a curved margin, deforming outwardly of the outer surface a cutting portion of the margin of each of the holes, thereby forming cutting edges, the cutting portions are curved outwardly of the outer surface, the cutting edges are curved tangentially of the outer surface and disposed to cut upon rotation of the acetabular reamer.

Abstract: A new and improved vehicle wash apparatus having a rigid arm with opposite ends. One end is journaled about a generally vertically extending pivot to a washer frame which extends over the vehicle being washed. The rigid arm at its distal end is journaled about a horizontally disposed pivot rod connected to a moveable arm extension having a distal end. A rotary brush is journaled at the distal end of the moveable arm extension for rotation about a vertical axis. The moveable arm extension and brush is moveable both inwardly and outwardly of the vehicle wash frame on both sides of the vertical position and being biased inwardly thereof.

Abstract: A new and improved tool driver having a shaft with a longitudinal axis and opposite ends. A boss is secured at one of said shaft ends by which the tool driver is connected to a rotary tool. A tool collate is secured at the other of the shaft ends by which the tool driver may be driven by a surgical hand piece having a chuck in which the collate may be positioned. The boss has a distal end surface with a groove therein. Both the groove and the distal end surface extend transversely of the axis. A pin is positioned in the groove on the axis. A latch mechanism is provided to hold a mounting bar of a rotary tool in the groove on the pin, whereby the rotary tool is held exactly coaxially of the driver during use. The rotary tool which is used with the driver has a bar which has the same dimensions as the groove in the boss of the tool driver of the invention. The bar thus fills the slot and is complementary to the slot. The bar has a hole therein which is complementary to the pin.

Abstract: An improved method of making stereoscopic pictures comprising photographing a scene with a camera spaced from the scene, moving the camera generally parallel to the scene while producing a plurality of pictures of the scene each taken at a different position relative to the scene, and separating the pictures into stereo pairs for viewing. In performing the method, the photographing and moving steps can be performed and the separating step can be done as soon as the pictures are available for viewing to produce the stereo pairs. Alternatively, the photographing and moving steps can be done at one time and the separating step can be done at subsequent times to produce the stereo pairs of the invention thereby allowing stereo pairs to be produced from existing motion pictures, videotapes and still photographs. The method can be used utilizing conventional photographic and viewing equipment in all existing mediums.
