Abstract:
A preset and prelubricated bearing (11) suitable for use with floating rear drive axle shafts of larger automotive trucks, has inner and outer race rings (12, 13, 17) with rollers (18) located between. The bearing (11) is sealed by means of seals (34) at each end of the race rings. The outer race ring (17) has a radial flange (19) to which the inner flange (20) of a brake arrangement (21) is attached by means of bolts (23). A flange ring (22) is also attached to the radial flange (19) by the bolts (27) which provides for attachment to the wheels of the truck and to the axle shaft. The bearing (11) enables disk brakes to be used on medium and heavy duty trucks.
Abstract:
An improved electronic evaporable substance delivery device delivers nicotinecontaining vapor to a user from a smoking device. The smoking device comprises a case having therein a power source, microprocessor, heating element and nicotine-containing cartridge. Microprocessor-controlled heating of the heating element causes air passing thereover to be heated. Passage of the heated air in proximity of the cartridge causes boiling of cartridge contents, and the release of a nicotine-containing vapor. A user may ingest the nicotine-containing vapor via a mouthpiece located at a first end of the case.
Abstract:
Apparatus for providing substantially uniform illumination with multiple, discrete sources of light include arrays of abutting light spreading elements, such as reflective light pipes or collimation lenses, for substantially eliminating visible boundaries between the sources of light. Methods for generating a substantially uniform field of emission include introducing light into such a spreader array. Light therapy devices including arrays of light spreading elements are also disclosed.
Abstract:
A light therapy technique includes gradually increasing or decreasing an intensity of light in a manner that approximates a change in light intensity during a natural light event, such as dawn or dusk. Graphs of the intensities of both the natural and simulated light events plotted over time may have an S, or sigmoidal, shape. The intensity curve of the simulated light event may be modified (e.g., a portion of the curve may be compressed or elongated relative to the corresponding portion of the curve of the natural light event) to provide a desired result, such as to allow a subject to sleep until an expected wake up time. Optionally, the color of light during the simulated light event may also mimic light coloring during the corresponding natural light event. Light therapy apparatus, such as clocks, that effect such methods are also disclosed.
