Abstract: An apparatus and method for generating thermoelectric power utilizes a hollow shell member having a cavity defined therein and a cartridge member disposed within the cavity, wherein the cartridge member has a combustion chamber defined therein. The cartridge member is mounted such that a space exists between the interior surface of the shell member and the exterior surface of the cartridge member. Thermoelectric elements are mounted to the exterior surface of the shell member such that no air spaces exist therebetween. A mixture of a combustible fuel and air is introduced into the chamber, the air/fuel ratio being less than the stoichiometric ratio for methane. Heat generated within the combustion chamber upon combustion of the fuel is transferred via the shell member to the thermoelectric elements which generate electrical energy in response thereto.

Abstract: A surgical network material is made from filaments of resorbable organic polymers with a thickness of about 50-300 .mu.m and/or of non-resorbable filaments or wires with a thickness of 100-750 .mu.m. The network which has an internal mesh width of about 1-10 mm, can be used, in particular together with bone cements based on polyacrylates or polymethacrylates, in combating bone defects.

Abstract: Apparatus is provided to facilitate viewing of one's facial image under controlled illumination patterns for purpose of either psychotherapy or merchandise selection.
Abstract: An orthopedic forearm splint intended to limit dorsiflexion of the wrist, without interfering with volarflexion and use of the hand, whereby ganglions of the wrist may be caused to regress. Applies the inventor's discovery that extreme dorsiflexion is the causative or aggravating factor in wrist ganglion. Comprises a light cantilever splint secured to the dorsum of the arm by one bracelet, with the distal end elongated beyond the bracelet in cantilever fashion past the wrist and freely apposing the hand, whereby it will strike the back of the hand if dorsiflexion is attempted, but does not interfere with volarflexion or normal work. Reversible to dodge ganglions and prevent chafing.
