Abstract: A cleaning aid for fabric washing machines is provided that improves the cleaning ability without using environmentally damaging detergents, excess water or longer cleaning cycles. The cleaning aid uses scrubbing devices having different buoyancy. The different buoyancy result in the scrubbing devices being distributed throughout the fabric cleaning machine, assuring that most areas of the fabric in the machine are benefited. The fabric scrubbing devices can be made with a material such as plastic or rubber. The scrubbing devices can be covered with flexible bristles to enhance their scrubbing ability. The shape of the bristles can be manipulated for particular uses. The resulting combination is a cleaning aid that can be used in conventional washing machines and improve the washing ability of these machines without damaging environmental side effects.

The shroud includes an end wall having an opening therein, a continuous sidewall extending from the end wall for encasing the heat exchanger elements and having an open end, and circulation members for moving a cooling medium through the shroud, the medium being admitted through the open end of the sidewall and being discharged through the opening in the end wall.

Abstract: An imaging apparatus (10) includes a scanning electron microscope (12) which is controlled to bombard numerous points (62) of a material sample (24) with an electron beam (18). Backscatter diffraction patterns are collected by an image collection system (26) which may include both a slower responding video camera (32) and a faster responding diode array (40). For a baseline point (62), an electron backscatter diffraction pattern collected at the video camera (32) is analyzed to identify representative pixels which reside along Kikuchi bands (78). Backscatter images from subsequent points (62) are rapidly compared (98) with the baseline to detect changes. When changes are not detected, EBSPs are not analyzed. When changes are detected, EBSPs are analyzed to generate new baselines. The resulting collection of analyzed EBSPs are processed (104) to identify microstructure attributes and to characterize defects (64).

The first end of the ferrule further including axially extending fingers with radially outwardly extending portions positioned to engage the tapered sidewalls of the chamber and force the fingers radially inwardly into a tube gripping position as the ferrule is partially withdrawn from the body so as to tightly grip a supply tube positioned therein and prevent the withdrawal of the supply tube from the ferrule.

Abstract: Symbols (18) of a burst (12) are sub-divided into symbol sections (20). Each symbol section (20) is sampled and converted into polar coordinates. A buffer bank (38) selectably delays the samples and replays a preamble (14). A demod bank (40) includes a coherent demod (58) and several differential demods (60). Each differential demod (60) processes its own stream of symbol sections (20). The differential demods (60) feed a preamble detector (66) and a symbol synchronization circuit (62). The symbol synchronization circuit (62) identifies the symbol section (20) which yields the smallest magnitude of frequency errors. This symbol section (20) is processed by the coherent demod (58) to acquire carrier phase and recover data. The coherent demod (58) is implemented in the phase domain so that only oscillation signal phase data need be generated in phase locked loops.

Abstract: An evaporator including a frame which defines a fluid inlet plenum and an interchangeable baffle plate positioned in the plenum along with an interchangeable fluid spray bar. A transition element carries fluid from a standard round tubular fluid inlet and distributes the fluid equally across the width of the spray bar. By forming a plurality of interchangeable baffling plates each having at least one of the placement, configuration and size of holes therethrough different than the other interchangeable baffling plates and forming a plurality of interchangeable spray bars each having a different fluid outlet configuration, the baffle plates and spray bars can be interchanged to design an evaporator for air conditioners and the like with the least amount of internal fluid pressure drop and the best fluid inlet flow balance with the best heat performance.

Abstract: An antenna (26) projects a detection zone (28) across a non-intersection portion (16) of a road (10). A scanning receiver (32) couples to and is controlled by a data logging computer (34). This computer (34) commands the receiver (32) to look for one FM local oscillator (LO) signal (22) that may be emitted from within the detection zone (28). If one LO signal (22) is detected, other LO signals (22) that may be detected at the receiver are ignored until the one signal is no longer detectable (90-106). An attenuator allows LO signals 22 emitted from radios (20) in the detection zone (28) at noisy frequencies to have the same likelihood of being detected as LO signals 22 emitted at less noisy frequencies. Detected LO signals (22) are ignored if they are detected for less than a minimum duration (100) or if they are detected for greater than a maximum duration (118).

Abstract: A thermo-magnetic vaporizer carburetor comprised of a vaporization reaction chamber which includes South pole exposed magnetic means uniformly around the chamber. The South pole magnetic field alters the molecular structure of the fuel so that it is more rapidly dispersed in the fuel/air mixture entering the I.C. engine. The liquid fuel enters the thermo-magnetic vaporizer under high pressure at ambient temperature and is conducted into a circular spiral arrangement of tubing of approximately six turns where the change-of-state transition is made from a liquid fuel to a fuel vapor. The circular spiral tubing assembly of the vaporization reaction chamber is the conduit for the fuel, as well as an electrical heating element that vaporizes the fuel that is flowing through it. The vaporized fuel exits vaporization reaction chamber and is directed to the exit port of the central vane gimbal where it is injected into the low pressure point of the spinning intake air vortex.
