Abstract: According to one aspect of the invention, it comprises a fireproof enclosure having a first and a second electrical terminal. The first electrical terminal is coupled to an electrical contact internal the fireproof enclosure. An actuating member is provided in the trip mechanism. A first end is inside the mechanism, while a second end extends outside. The actuator member is biased to have the first end in contact to the electrical contact at a first position. The first end has a bimetallic latch coupled thereto. The bimetallic latch comprises a contact portion at the point of coupling to the first end and a first and second wing portion extending from the contact portion. Ledges are disposed on the interior of the trip mechanism. The wing portions engage the ledges to hold the actuator member at a second position. The second position establishes a gap between the electrical contact and the contact portion of the bimetallic latch.

Abstract: A connector is fabricated from dielectric material, typically ceramic, to enable the isolated assembly of neon connections, the plugging in of neon tubes, and the maintenance of high voltage neon connections (in the order of 30,000 volts). The connector includes a dielectric housing and separate dielectric cover plate with an optional silicon rubber gasket therebetween. In connector assembly, commonly bound, oppositely-polarized high voltage wires enter a common chamber defined between the backside of the housing and the mounting. On the front side of the housing are first and second paired and communicated chamber sets. Each set of chambers includes a connector chamber and a tube receiving chamber. The connector chamber receives an insulated wire of one polarity from the common housing at the connector back and provides an isolated dielectric cavity in which the wire is stripped and electrical conductor connection made.

Abstract: A specialized sign fitting together with the process of using said sign fitting to install signs on sign supports, such as walls, is disclosed. The specialized sign fitting includes a threaded male member having a protruding attachment member, such as a wood screw, for fastening to the back of the sign. The fitting has an overlying female member having the external configuration of a bolt. This mounted bolt configured female member is used to rotate and fasten the male member at the protruding attachment member into the sign. With a plurality of fasteners installed on the back of the sign, the female members are removed to expose male member mounted scribes. In the shop, these female member mounted scribes are then impressed with the sign iself onto a sign mounting templet. In the field, the templet containing both the scribed locations of the sign fasteners as well as typically an outline of the sign is first hung on the sign mounting location.

Abstract: A low energy sign contruction is illustrated for illumination of signs of the type having translucent illuminated faces. An opaque sign border is bridged by a reflector extending generally parallel to the illuminated face and having a truncated sawtooth profile. For single sided signs, one set of sawtooth points is truncated; for dual sided signs, both set of sawtooth points are truncated.Bayonet mounted lighting sockets are mounted at apertures in the respective truncations and utilize the metallic reflective surface as one side of a low voltage (10.5-volt) AC circuit. The reflector forms a cooled heat sink mounting the bulbs as well as a supporting matrix. The lamps, as mounted to this supporting matrix, are typically spaced at distances which do not exceed twice the distance of the lamp filament to the translucent face. By the expedient of using 14-volt lamps, prolonged lamp life with low energy illumination results.

Abstract: A three-dimensional sign character is formed with improved circumscribing opaque metal sheet strip siding. The sign, typically having an interior light source, includes a translucent plastic face circumscribed by opaque sheet metal strip siding. The sheet metal strip siding includes a plastic strip bonded directly by gluing to a freshly abraded band on the sheet metal strip. Convolute folds are formed on either side of the sheet metal strip. One convolute fold is formed adjacent an edge of the plastic strip so as to extend angularly above and abut the plastic stripping to function as a light stop. The secured plastic strip serves as the bonding point to the translucent face of the sign.
