A human head restraint system for positively restraining the human head in a predetermined position utilizing eccentrically pivoted cams on either side of the predetermined position for engaging various sizes of human heads. The active area of the cam profiles are non-circularly shaped for insuring that the area of actual contact with most human head sizes is close to a line passing through the cam pivot points thus minimizing the effective lever arm available to the restrained head for effectin...

An anatomical part simulacrum wherein a core is enclosed within a skinlike glove and the method of forming the simulacrum by separately forming a core and a glovelike element and thereafter applying the element to the core.

A disposal system for human waste incorporating vacuum and heat emitting means to reduce human waste to sterile, bacteria free gases; and, harmless, odorless powders. The system is particularly useful in mobile facilities, such as boats, ships, and the like.

An incinerator for disposing of sewage that incorporates a combustor to develop high temperatures and an injection tube to deliver heat directly to the sewage. The sewage is vaporized and passes through a residence chamber. The residence chamber is raised to an elevated temperature of approximately 1600 degrees F. by gas from the combustor. This high temperature oxidizes any organic contaminates. The exterior surfaces of the device are maintained at close to ambient temperatures through the use ...

Means for controlling the outflow of two fluids having different physical and/or chemical characteristics, particularly hot and cold water for the treatment of hair, to provide discrete sprays of said fluids from an array of jet ports, which includes A body member having two sets of fluid passages which are adapted to communicate respectively with sources of the two fluids under pressure; A closure member slidably mounted relative to the body member and carrying the array of jet ports which are ...

An appliance for use by the human male for facilitating erection of the penis which reacts on a circulatory blood flow in a manner which will impede the flow of blood from the penis and simultaneously not materially impede the flow of blood to the organ.

Apparatus by means of which the muscles of the human body are used to develop energy. This may be done in order to exercise the muscles, or to use the muscles to develop useful power. The apparatus may be an exercizer only, a device for causing a patient to perform certain exercises for patient assessment, a vehicle, or a unit for developing power for some useful purpose.

A joint for use in a human neck simulator of the type which includes a number of vertebra simulating members arranged in a stacked relationship in alignment with each other and connected for multidirectional angular movement cushioned by viscoelastic material to provide the simulator with lifelike characteristics when subjected to impact loadings. The joint includes a pivotal connection between the two lower vertebra simulating members of the simulator and the axis of movement of this connection...

An instrument for administering to the human eye, either for medicinal or cosmetic purposes having a body of substantially sterile, resinous, organic material, such as a thermoplastic polymeric material like polyethylene, having a contact section provided with an outwardly directed concave contour. The contour section or portion is adapted to be placed in close proximity to and in matching configuration in contact with an upper and/or lower side of the human eye to steady the eye and facilitate ...

Human parathyroid hormone was isolated in highly purified form from human parathyroid adenomas. The primary sequence of the amino terminal 34 residues was determined and the peptide of the first 34 residues synthesized.
