Abstract: A braid singeing clamp for singeing the end of a braid to prevent said braid from coming undone. The braid singeing clamp comprises a pair of pivotally connected clamping surfaces having grips on one end and heating elements on the opposite end. The heating surfaces are attached to each clamping element by a set of rings which are situated on the top portion of each surface. The rings slide over a tube portion of each clamping element, and secure the heating surfaces to the clamp. Alternatively, the heating surfaces may snap into sockets positioned on the tube portion of each clamping element. The heating elements are shaped to envelope the lower portion of the braid and provide heat only to the braid end.

Abstract: A telephone line access control apparatus to restrict access to an outgoing telephone line may be placed in a locked mode to restrict access to the telephone line, or in an unlocked mode to enable full and unrestricted access to the controlled telephone line. The apparatus supports the answering of all incoming calls, and when in the locked mode restricts access to the telephone line by enabling a person to dial only preselected emergency telephone numbers. The invention is configured with a filter, which may be coupled to the telephone line, as required, to restrict the dialing and placing of unauthorized telephone numbers. Another embodiment of the invention is arranged with a plug that may be plugged into a telephone jack in a secured manner so that the apparatus may only be unlocked and removed from the telephone jack by individuals having a key.
