Abstract: A desirable sign structure can be formed using a hollow, integral, self-supporting thermoplastic polymer body shaped so as to include a hollow border or peripheral frame carrying front and back walls of the sign structure. Grooves adapted to carry extensions on interchangeable letters may be provided in the front wall. When such grooves are used, the back wall preferably includes grooves or furrows reinforcing the front wall. A slot can be provided in the front and back walls in such a manner as to separate the front and back walls into two panels or panel sections. When such a slot is used, guides or tracks are preferably employed so as to mount a shutter in the slots, the shutter being capable of movement in order to cover or uncover one of the panels or panel sections.

Abstract: An electric soldering iron having an elongated handle with an electric heating element attached therein and including a removable tip member located to receive heat from the heating element and a holding member to hold the tip relative to the heating element is improved by forming said heating element as an elongated flat blade heating element having a elongated flat planar heated surface. The heating element is so located in the handle to extend outwardly from the handle. The tip member includes a body having an elongated flat planar heat transfer surface which fits against the planar heated surface of the heating element and receives heat therefrom. The tip member further includes an operative tip extending away from the remainder of the tip member. A retaining tube detachably secured at one end to the handle fits over the heating element and tip member and except for its operative tip and maintains them in a fixed relationship with respect to each other and to the handle.
