Abstract: A heat sealing instrument for use in the treatment and prevention of hair loss and stimulation of new hair includes a heating element, a protective shroud, a handle, and control circuitry. The heating element is heated to a temperature of from about 400 to about 1,000° F. sufficient for fusing and sealing the cuticle, cortex, and medulla layers of a hair shaft. The instrument includes a control panel for monitoring and adjusting the temperature of the heating device and a vacuum source and filter combination for drawing in and filtering the fumes from the area around the heating element.

Abstract: A protection system for monitoring the operation of a part molding machine which ejects the part from the molds after successful completion of the molding process. A plate is disposed beneath the mold for receiving the parts after they are ejected. A transducer mounted on the plate provides a spectrum of signals having different frequencies when the part impacts the plate. The amplitude of these signals at particular frequencies depend upon the part being made by the machine. A frequency generator is used to selectively provide a reference frequency signal associated with the particular part being made. A tone decoder compares the reference frequency signal with the signals from the transducer and provides an output signal if the amplitude of the transducer signals at the reference frequency exceeds a predetermined level.
