Abstract: There is presented an inexpensive control lock or locking device for preventing changing the state of a toggle switch from an open circuit to a closed circuit or from a closed circuit to an open circuit. The control lock bears against the projecting lever of a toggle switch to prevent movement of the projecting lever and thereby prevents changing the state of the toggle switch.

Abstract: A method and an apparatus for forming elongated composite parts having constant cross sections. The apparatus comprises a form having a cross section, a portion of which is complementary to a first portion of the desired cross section of the elongated part. The apparatus further comprises a holding means having a cross section, a portion of which is complementary to a second portion of the desired cross section of the elongated part. Plies of preimpregnated composite material are held within a slip tape, which, in turn, is forced against the complementary cross section of the form by the holding means. The apparatus is then passed lengthwise along the slip tape enclosing the preimpregnated plies of composite material to cause the slip tape to tighten around the preimregnated plies and to generate a slip tape-enclosed, elongated part which is appropriately shaped to pass through a pultrusion die.
