Abstract: A display rack system for use in a display case such as a produce display case includes a base and a back wall. Mounted on the back wall are a series of shelves, which affix to holes in the back wall. Certain of the shelves are curved or sloped upwardly or downwardly relative to the base. In a preferred embodiment, the shelving unit is in the form of a box having a curvilinear upper and lower walls and vertical sidewalls.

Abstract: A fluorescent lamp includes a ballast releasably connected to an adapter in a bayonet style connection. The adapter includes a locking tab for preventing removal of the adapter from an electrical socket once the adapter has been installed in the electrical socket. The fluorescent lamp has a lamp tube. The lamp tube is preferably connected to a base in a manner to minimize the total height of the fluorescent lamp. The lamp base is preferably provided with a recess in which contact pins are connected to the lamp base. The lamp may be directly connected to the ballast. The lamp tube may be arranged in a coil having a greater radial outer extent than the base or than the ballast.

Abstract: A fluorescent adapter having a housing including a tip contact compatible with an electrical socket, a threaded ring contact compatible with the electrical socket, the ring contact surrounding the housing and rotatable with the housing when the housing is rotated in a first direction and not rotatable with the housing when the housing is rotated in an opposite direction, and a fluorescent ballast supported by the housing and having input electrodes in electrical contact with the tip contact and the ring contact, respectively, and output electrodes for removably receiving the contact pins of a fluorescent lamp. The adapter is easily inserted into the socket but is not removable after insertion.

Abstract: Apparatus, for example an inhaler, is disclosed in which a spray is formed electrostatically from an outlet 6 to achieve uniform droplet size. The spray is then discharged for its intended use--in the example inhaling. The spray is discharged completely by corona produced by a sharp discharge electrode 16 which is charged to a polarity opposite that of the liquid. In order to prevent the corona from spoiling the formation of the spray itself, the liquid of the outlet 6 is protected by a neutral shield electrode 8. The spray issues through a hole 14 in the shield electrode. The hole is sufficiently small to prevent corona getting through, yet sufficiently large to allow the spray through.

Abstract: The present invention provides a suspension lighting fixture utilizing a chain suspension for the lamp holder, and which fixture is attached at its upper end, mechanically and electrically, to an outlet box and to conductors mounted in the ceiling, respectively. The length of the suspension chain is adjustable without requiring cutting or parting of the same. The installation may be expeditiously and cheaply made and the structure involves a minimum of materials. The invention utilizes as an essential element a hanger which is adjustable relative to the individual links of the chain employed and through which hanger the swing canopy may be clamped against the ceiling by cooperating screw threads on said hanger and on the swing canopy.
