Abstract: Disclosed compressor embodiments can prevent or substantially reduce the inefficient upwardly spiraling heat buildup found in typical compressors by significantly increasing the surface area of mating piston and chamber walls, using the meshing and undulating geometry of the piston/chamber walls to create increased air turbulence in the chamber and generate more air flow against the cooling walls, promoting turbulence even more by varying the axial path of the piston head so that it is not simply linear, using fluid to cool the non-working side of the piston, and/or providing additional cooling features (such as fins) on the non-working side of the piston to provide still further cooling means for the piston head. Analogous principles can also be included in wobble-plate compressors, scroll compressors, blowers, and other compressor types.

Abstract: A light fixture includes a plurality of fluorescent bulbs wherein a light intensity of each of the plurality of fluorescent bulbs is related to the operating temperature of the fluorescent bulbs, a sensor for sensing a physical parameter related to the light intensity, and a circuit adapted for monitoring the sensor and controlling the operating temperature of the fluorescent bulbs to maintain the operating temperature of the fluorescent bulbs within a range having a lower temperature and an upper temperature. A method of maintaining light intensity of fluorescent bulbs in an environmental chamber includes monitoring a physical parameter associated with the light intensity of the fluorescent bulbs in an environmental chamber and adjusting temperature of the fluorescent bulbs in the environmental chamber to maintain an optimum light intensity of the fluorescent bulbs in the environmental chamber.

Abstract: An apparatus including a surface containing at least one embossing element. The embossing element having a first sidewall angle and a second sidewall angle and wherein the first sidewall angle is different than the second sidewall angle.

Abstract: Embossed and rolled tissue products are disclosed. In particular, an embossing pattern is used that enhances the softness and bulk of a tissue product without a substantial degradation in strength. The embossing patterns of the present invention are particularly well suited for use with bath tissues and with webs that have not been through-air dried. The web can be, for instance, a wet-pressed web that has been creped.

Abstract: A wearable article equipped with a multi-level alert system detects and emits signals corresponding to various abnormal levels of a substance in a mammalian extract. By providing different signals corresponding to multiple abnormal levels of the substance, the wearer is simultaneously alerted to the existence of an abnormality, and informed of the level of severity.

Abstract: A cable severance tool (10) having approximately flat cutting edges (40). An opening (41) formed by the edges (40) as the severance heads move together is preferably approximately elliptical, oval or hexagonal-shaped. The flat severance edge (40) and the elongated opening (41) formed, allows hardened steel strands (4) of wire cable (1) to be gathered and severed rather than cut.
