An Ag—Al—Cu alloy coating layer in the rearwardly-disposed cavity improves heat conduction from the heater therein.

Abstract: Disclosed is a heat transfer system, the heat emanating from a regular light bulb wherein the heat generated by the filament within the glass of the light bulb is generally wasted by exposure to the environment. The regular light bulb is surrounded by a metallic heat shield in close proximity to the light bulb. The heat shield itself is surrounded by a coiled tubing having a medium that will heat because of the influence of the heat from the light bulb. The heated medium will be transferred to another location to heat another medium such as water, for example. The light will also be transferred to another light emitting source to light a predetermined area. The light transfer may be accomplished by a glass fiber optic cable which will transfer the light energy from the initial light source, the light bulb, to a new source of a light receiving device.

Abstract: An infrared welder for thermoplastic materials comprising the combination of a halogen lamp producing illumination in the infrared band located at the focal point of a first parabolic reflector. The parabolic reflector is joined in a substantially continuous fashion with a non-imaging lower reflector such as a Winston cone or a “CPC” having a lower aperture through which essentially all of the radiation from the source is directed. The aperture defines the shape and size of the weld area. The lower reflector may be brought into contact with the thermoplastic materials during the welding operation. Alternatively, a selectively operable press device may be used. Several embodiments are disclosed including embodiments which produce circular spot welds, linear welds, curved welds and corner welds.

Abstract: An incubator hood for an incubator for premature and newborn babies as well as to a process for regulating the temperature of an incubator hood are provided. The problem frequently occurring in incubator hoods is that the incubator hoods lead to heat losses at the premature and newborn babies and that water of condensation precipitates on the inside of the incubator in such incubator hoods, and this water of condensation obstructs the view and facilitates the growth of microorganisms in the incubator. This can be counteracted by a heated incubator hood. The comparatively complicated regulation processes, which requires the installation of temperature sensors in the incubator hood is avoided by the use of interior heating wires (1) in which temperature-dependent electric resistors (3), preferably PTC resistors with a nominal response temperature of about 37° C., are arranged.

Abstract: A biopsy site marker comprises small bodies or pellets of gelatin which enclose substantially in their interior a radio (X-ray) opaque object. The gelatin pellets are deposited into the biopsy site, typically a cylindrical opening in the tissue created by the recent use of a vacuum assisted large core biopsy device, by an applicator device that includes an elongated cylindrical body that forms a flexible tube and a piston slidable in the tube. One end of the tube is placed into the biopsy site. Typically, several gelatin pellets, only some of which typically do, but all of which may contain the radio opaque object, are deposited sequentially into the site through the tube. The radio opaque objects contained in the gelatin bodies are of a non-biological configuration and readily identifiable as man-made object, so that in observation by typical mammography equipment they do not assume the shape of a line, whereby they are readily distinguishable from granules and lines of calcification.

Abstract: A heating apparatus has a spectral selective type heat radiating material having a high emissivity in a specific wavelength region. A film of the spectral selective type heat radiating material is formed on a surface of a heat radiant while leaving at least one region of the surface of the heat radiant with nothing formed thereon. The film is applied so it is possible to identify whether or not the heating apparatus is operating and to prevent the temperature of a surface of the heat radiant from rising excessively. The spectral selectivity of spectral emissivity is controlled by adjusting the thickness of the film of the spectral selective type heat radiating material.
