Apparatus employing a non-invasive method for objectively determining in vivo, the rate of oxygen utilization in peripheral tissue by spectral measuring means, containing a light source, a clamp or tourniquet for occluding a segment of blood in the tissue, means for transmitting the light through the isolated segment of blood to pick up the spectral values of the oxyhemoglobin for two selected wavelengths, wherein the rate of reduction of the oxyhemoglobin of the blood as determined at one wavelength is faster that the rate of reduction of the oxyhemoglobin at the other wavelength, means for converting the spectral values individually for the two selected wavelengths into current flow, and means for determining the time-space relationship between the changing spectral values of the two selected wavelengths, from the moment of occlusion.

A heel having a circular wear-element spring-locked to a heel base, in which position the wear-element may be manually unlocked against the spring action to permit rotation and relocation in a new position on the heel base, and being manually releasable for spring-locking in the relocated position.

The pen consists of two pen bodies, preferably identical, which interlock with each other in a plurality of longitudinal positions. Each of the pen bodies is preferably provided with a seat for positioning a ball point cartridge therein. Movement of the pen bodies will cause the cartridges seated therein to be protracted or retracted.

A non-invasive method of objectively determining, in vivo, the rate of oxygen utilization in peripheral tissue by spectral measuring means, which involves isolating a segment of blood in the tissue with a clamp or tourniquet, and obtaining rapid, successive spectral curves of the oxyhemoglobin in the occluded area, to and from selected wavelengths of light, and measuring the time-space relationship between a rapidly moving portion of the spectral curve and a slower moving adjacent portion of the same curve, from the moment of occlusion, to establish a rate of reduction of the oxyhemoglobin in the tissue which is directly correlated to the rate of oxygen utilization.

An article of manufacture such as a towel or article of clothing made of a sheet material having a compliant absorbent surface on both sides thereof made of fibers having little 'wet strength', and in between a thin layer of compliant plastic material as a reinforcing support with an adhesive uniformly applied on both sides thereof which is flexible, thin and insoluble when wet and which will not strike through the absorbent material nor change its appearance.

A drip-coffee maker having a coffee dispersing section mounted to a coffee receiving vessel, the latter characterized by having double walls provided with an evacuated space therebetween, a filter contained in the dispersing section to filter the coffee into the vessel, and a venting means positioned between the dispersing section and the vessel to provide atmospheric connection between the vessel and the atmosphere.

The method of changing the entire buccal surface area of a tooth, which comprises applying a layer of glue to the entire buccal area of the tooth and thereafter blowing powdered particles having the desired color, on the buccal surface, said glue being sufficiently tenacious to permanently lock said particles to the glue, and said particles having a hardness approaching that tooth enamel.
