Abstract: A recessed lighting unit for mounting to a ceiling or a wall is provided. The recessed lighting unit includes an interface module having a through-duct. The through-duct may be coupled to a wire connector assembly to secure an electrical wire to the interface module and allow the electrical wire to reach a light source module. The wire connector assembly may be twisted and locked to the interface module without the use of tools. The lighting trim may be snapped on to an interface module through the use of a flexible retainer ring. The lighting trim may also be twisted and locked to an interface module without the use of tools. The present invention provides for a reduced set of components while ensuring adaptability and easy installation of lighting units. Other embodiments are also described and claimed.

Abstract: A gel slicer consisting of a support with a gel guide trough and a feed screw journalled parallel to the trough. A feed plunger assembly is threadedly engaged on the feed screw and has a plunger portion slidably engaged in the trough. The feed screw is intermittently driven by a power shaft via selectable identical-diameter gear discs with different-length tooth configuration for varying the increment of feed of the gel per revolution of the power shaft. The gear discs have smooth peripheral portions providing dwell periods of the feed screw. A pivoted transverse cutting blade is spring-biased toward cutting position over the trough and is held elevated by a follower lug engaging a cam on the power shaft, the cam having a blade-release notch. The cam is synchronized to release the cutting blade during the dwell period of the feed screw. Thus, the thickness of the slice depends on the amount of teeth on that gear disc which is selected to drive the feed screw.
