Abstract: A connector for interfacing a disk drive, into which a floppy disk is to be loaded, with a controller card of a personal computer. The connector replaces the printed circuit board which has previously been used to interface the disk drive and computer. More particularly, the connector includes socket and plug portions which emulate the box connector and edge card, respectively, of the conventional circuit board interface. Accordingly, and by virtue of the presently described connector, the disk drive may be more directly and reliably interfaced with the computer while eliminating the conventional printed circuit board and the relatively high cost and space consumption that are characteristically associated therewith.

Abstract: A fluorescent lighting fixture or luminaire in which the conventional number of light source is de-lamped to a lesser number and which provides acceptable light levels and distribution of light. A flexible reflector of specular reflective material is installed in the fixture above the replacement lamp. The reflector material by virtue of its flexiblity will assume a generally parabolic configuration to re-direct the light from the fixture. Thus, with the reflector, two-lamp luminaires will de-lamp to one-lamp and four-lamp luminaires may be de-lamped to two-lamps, and so on. The invention also provides an electrical connector for positioning a new lamp at a central location and which connector is engageable in the existing lamp holders.
