Abstract: A printed wiring board file employing guide tracks of wire construction to engage guide runners of printed wiring board assemblies to be mounted therein. The guide tracks are assembled to lateral positioning members at regular or optionally, predetermined differing spacings and each guide includes a forwardly projecting divergent lead-in area to assist in aligning the board assembly guide runner with the file guide tracks. A pair of depressions are formed in each guide track to engage corresponding projections in the guide runners to retain the board assemblies in their fully inserted position within the file.

Abstract: A printed wiring board assembly including a printed wiring board including a pair of guide runners attached to an upper and a lower edge thereof. The guide runners include an elongated body, a pair of elongated walls extending the length of and from one side of the body, and a groove formed the length of and on a second opposite side of the body. Projections extend from one of the elongated walls through apertures in the printed wiring board to retain the guide runners in engagement with the board. Protrusions extend into the groove and engage depressions in guide tracks of an associated printed wiring board file to lock the board assembly in its fully inserted position within the file.

Abstract: A telephone handset support which will allow a telephone substation to be used as either a desk or wall unit, wherein, the telephone base includes a T-shaped cavity on a face thereof, arranged to accept therein a similarly shaped retainer. The retainer is alternatively positionable to be substantially housed within the cavity, allowing the telephone instrument to be horizontally mounted, or to have an included hook extend outward of the cavity. The hook engages an orifice on the handset supporting the handset to the base when vertically mounted.
