Abstract: A head transport assembly includes a sled supporting a magnetic head for movement along a guide path generally oriented toward the drive spindle of a drive motor. The sled, which is supported against a guide rod defining the guide path, includes two adjustment points along the guide rod--a first adjustment point proximate the head and a second adjustment point outboard of the first in relation to the drive spindle. By acting on the first point to pivot the sled about the second point, the head is brought onto a true radial path intersecting the center of the drive spindle. The azimuth of the head is next adjusted by acting on the second point to pivot the sled about the first point until the desired azimuth angle is obtained.

Abstract: Improved light reflector apparatus for use in an electronic flash unit or the like is formed by an injection molding operation, which causes both precise shaping of a reflector and accurate mounting of the reflector securely within a housing. A light-reflecting flexible sheet is placed in a mold so that its light-reflecting front surface is centrally positioned adjacent a mold forming surface. The forming surface, which is larger than the sheet, has a contour adapted for shaping the sheet to reflect light into a beam of illumination. Liquid plastic is injected into the mold under pressure against the opposite surface of the sheet, thus pressing its light-reflecting surface into intimate contact against the forming surface. Because the sheet is smaller, the border of the forming surface is not covered by the sheet. Plastic flows beyond outer edges of the sheet against the uncovered border of the forming surface.

Abstract: A camera includes (1) a socket for detachably receiving a flashbulb, (2) a flash sensing member for detecting the presence and absence of a flashbulb in the socket, (3) a diaphragm for adjusting an exposure aperture as a function of whether the ambient light is bright or dim, and (4) a photosensor, responsive to visible light and infrared (IR), for controlling an exposure in accordance with the total visible light and IR passing along a light path to energize the photosensor during an exposure interval. An IR-attenuating filter is mounted for movement between a normal first position in alignment with the light path for effectively blocking IR from impinging upon the photosensor, and an actuated second position outside the light path to enable IR to energize the photosensor.
