Abstract: A distributive coupler for use with at least one set of optical fibers includes a fiber optic terminal for supporting the end portions of each set of optical fibers. In a reflective mode, the coupler is adapted for use with one set of optical fibers by directing light transmitted through any one or more of the optical fibers back onto the set of optical fibers. A reflecting element is utilized to reflect transmitted light toward the set of optical fibers and a focusing element is utilized to focus reflected light onto the set of optical fibers. In a transmissive mode, the coupler is adapted for use with two sets of optical fibers by directing light transmitted through any one or more of the optical fibers onto the other set of optical fibers. A shaping element is utilized for shaping light transmitted toward the other set of optical fibers and a focusing element is utilized for focusing transmitted light onto the other set of optical fibers.

Abstract: An evaporative cooler having a one-piece, frameless shell secured to a bottom pan and having a top cover hinged along one edge to the side wall of the housing shell. A quick-release latching mechanism secures the top cover to the opposite side wall to hold the top cover closed while permitting the top cover to be easily opened for access to components of the evaporative cooler housed therein. Evaporative media pad assemblies have side frame members having V-shaped outer surfaces which slide in correspondingly shaped tracks in the corners of the shell to space the pad assemblies from the louvered side walls of the shell and permit the pad assemblies to be installed and removed from above with a vertical sliding movement.

Abstract: Apparatus for continuously lubricating a conveyor belt with a mixture of water and soap or detergent during normal operation and for washing the conveyor belt during a preselected time interval after normal operation has ceased. Solenoid valves are interposed in water lines to a lubricating nozzle and wash nozzles to control the flow of water to the nozzles, and pumps are provided to inject soap or detergent into each of the water lines. During normal conveyor operation, electrical power is supplied only to the lubricating line solenoid valve and the lubricating line pump to produce a lubricating spray of water and soap or detergent from the lubricating nozzle which is directed onto the belt. When the master on-off switch is switched to the "off" position, a wash timer is actuated for a predetermined interval of time and cooperates with a relay to also enable the wash line solenoid valve and the wash line pump to deliver water and soap or detergent to the wash nozzle for cleansing the conveyor belt.

Abstract: An improved electric cooking appliance such as a hot plate, range or griddle, particularly for use in a commercial countertop application. This class of appliance has a case supporting an electric heating element and the space between the heating element and the bottom of the case is limited because of the height restrictions of the counter type appliance. The improved appliance has a baffle extending across the entire breadth of the case below the heating element and separating the case into the heating element compartment on the upper side of the baffle and the control compartment located on the lower side. The controls including a switch or the like are located in the lower compartment and thereby are separated from the heating element by this baffle. Both the heating element compartment and the control compartment are provided with openings in the case at opposite sides of the compartment to allow convective airflow cooling of the compartment.

Abstract: A built-in well type food warmer includes a heating element assembly which is separably engaged with the underside of a food well by adjustable hanger members. The heating element assembly includes an upper heat distribution plate which is nestable within a recess formed in the bottom of the food well. The heating element assembly is enclosed by a tray member which is resiliently mounted within an enclosure. Brackets extending outwardly from the enclosure are attached to the lower ends of baffle hangers which extend downwardly from an upper rim of the food well. The hangers are formed of two separable members, adjustably connected together for selectively adjusting the length of the hanger. As the hangers are shortened, the heating element assembly is resiliently biased into contact with the bottom surface of the food well within a recessed portion thereof.

Abstract: A grass trimmer includes a housing having a lower base wall from which extends a hub member of a predetermined height coupled to a motor encased in the housing, which motor drives the hub member rotatably. A cutting line element is attached to the hub member. A rim extends outwardly from the housing about the perimeter of the base wall. A first rim portion is of a height greater than the hub member and includes first and second spaced mounting ears extending therefrom toward the hub member. A protective shield designed for mounting on the housing in spaced relation from the base wall, is planar and of a similar shape to the base wall. The shield includes first and second tab and shoulder assemblies located for cooperation with the ears on the rim portion of the housing. Joining the last mentioned assemblies and respective ears attaches the shield to the trimmer housing.

Abstract: A temperature sensitive timing control device for a toaster appliance includes a main bimetal element and a compensating bimetal element, both mounted on a support member mounted for pivotal movement in first and second directions, but biased toward the first direction. The main bimetal element includes a trigger arm normally engaging a latch release member to maintain the member in a set position. The latch release member when released by the trigger arm, in turn releases the bread carrier latch mechanism. The free end of the compensating bimetal element rests on a limiting screw which determines the extent of movement of the support member in the first direction. A locking member, operated by the toaster bread carrier when the latter is moved into a toasting position, engages the support member to secure it against movement in the first direction. When the bread carrier is moved to the toasting position, the bimetal elements are heated.
