Abstract: A concealable surgical light device such as for a birthing room has a frame for supporting the light on one side and a decorative panel on the other side. The frame includes reinforcing ribs positioned in a Y shape, and a cylindrical section at the intersection of the ribs for attaching the light. The frame is rotatably supported inside a housing which is fixed within the ceiling structure. At one end of the housing there is a fixed tube and a bearing and at the other end is an output shaft of a speed reducer gear connected to the frame through a torque limiter and slip clutch for rotatably supporting the frame. Wires are fed through the tube without being subjected to rubbing or twisting. In a closed position of the frame, the light is concealed within the ceiling structure and the decorative panel is flush with the ceiling. In an open position, the light is deployable as it faces into the birthing room.

Abstract: A drain closure comprises a drain stopper having a downwardly projecting sleeve, an upwardly extending post loosely received in the sleeve, and structure carrying the post, the sleeve having at least one opening through the side thereof, and a spring carried by the sleeve and having an arm received in that opening to frictionally engage the post, whereby the sleeve, spring and stopper are adjustably movable up and down relative to the post, against frictional force exerted by the spring arm engaging the post as the arm slides relative to the post.

Abstract: A toothbrush having an elongated handle provided at one end with a head comprising a surface from which bristles project in the usual manner. Within and extending longitudinally of the handle is an elongated cartridge chamber terminating at the head end of the handle with an opening communicating at one end with the chamber and at its other end with the bristled surface. The cartridge chamber is adapted to receive therein an elongated, tubular, flattenable, dentifrice cartridge insertable through an opening at the end of the chamber remote from the head. A dispensing member slidable longitudinally of and within the chamber is engageable with the cartridge to flatten such cartridge progressively from the remote end of the handle toward the head end thereof, thereby dispensing the dentifrice into the bristles of the toothbrush through an elastomeric, tubular cartridge tip disposed in the opening in the toothbrush head and extending beyond the bristled surface.

Abstract: A toothbrush having an elongated handle provided at one end with a head comprising a surface from which bristles project in the usual manner. Within and extending longitudinally of the handle is an elongated cartridge chamber terminating at the head end of the handle with an opening communicating at one end with the chamber and at its other end with the bristled surface. The smaller of the two angles between the opening and the bristled surface is no more than about 45.degree.. The cartridge chamber is adapted to receive therein an elongated, tubular, flattenable, dentifrice cartridge insertable through an opening at the end of the chamber remote from the head.
