摘要:
A hybrid propulsion system (8) for powering vehicles (V) such as class 8 DOT classified semi-tractor trucks under normal load conditions and at highway speeds comprises an internal combustion engine (14), an AC generator (20) powered by the engine (14), DC battery packs (26, 28), an AC/DC controller (22), and an AC electric motor (32) driving the drive train (33) of the vehicle (V). The AC generator (20) and the DC battery packs (26, 28) provide input to the AC/DC controller (22), which, in turn, converts the DC input from the DC battery packs (26, 28) via a DC circuit to AC so that the output from the AC/DC controller (22) to the electric motor (32) is AC for powering the vehicle (V). The DC battery packs (26, 28) may comprise thin plate flooded lead acid cells and may be connected in series, in parallel or a combination thereof. Vehicles (V) may be retrofitted to incorporate the propulsion system (8).

A self -aligning bearing assembly (10) is disclosed which is capable of reacting both radial and axial loads. An inner bearing race (12) is connected to a rotatable shaft that is subjected to such loads. An outer bearing race (20) is installed within a housing (30) and is capable of movement in multiple directions with respect to the housing. The outer bearing race can rotate in planes corresponding to longitudinal sections of the outer race, i.e., rotational displacement. In addition, the outer bearing race can translate with respect to an inner wall of the housing in an axial direction of the housing, i.e., axial displacement. Such movemen is enabled by the use of radially displaceable thrust rings (40,42) which contact the outer bearing race, and control of the geometry of the outer bearing race and inner wall of the housing.

An apparatus (10) for fabricating fiber reinforced plastic structures is disclosed. In detail, the apparatus includes a mold surface (14) upon which can be supported a lay-up (16) of one or more layers of a fibrous material (16A, 16B, 16C, 16D), and over which can be placed a fluid impervious outer sheet (26) with an inlet port (28) and having its edges (30) marginally sealed (32) upon the mold surface (14) to form a chamber (34). A vacuum outlet (35) is connected to the chamber (34) for drawing a vacuum there from. A resin distribution system (20) is positioned between the lay-up (16) and the fluid impervious sheet (26). The resin distribution system (20) includes a resin distribution medium (22) for receiving resin from the inlet port (28) and a resin containment layer (24) between the resin distribution medium (22) and lay-up (16) for preventing resin flowing from the resin distribution medium (22) into the lay-up (16) until the resin distribution medium (22) is substantially filled with resin.
摘要:
A method of screen printing and laser ablating various types of substrates (10) is disclosed. The process may be used to make decorated (12, 14, 16) auto glass with additional indicia (20a) such as serial numbers, bar codes, and the like. The substrate (10) with the applied coating may subsequently be shape formed and/or heat strengthened to produce a final product. The invention also provides a screen and a screen printed pattern which include a portion (20) that is subsequently laser ablated to provide specific information such as serialization. In one embodiment, the screen printed and laser ablated glass substrate (10) is fired. In another embodiment, screen printed patterns (20) may be laser ablated with no subsequent heat treatment required.
摘要:
Methods and apparatus are disclosed for remediating metal contaminants using hydrocarbons which stimulate the growth of hydrocarbon-utilizing bacteria. The metal contaminants may include heavy metals such as arsenic, antimony, beryllium, cadmium, chromium, copper, lead, mercury, iron, manganese, magnesium, radium, nickel, selenium, silver, thallium and zinc. The hydrocarbon may include alkanes, alkenes, alkynes, poly(alkene)s, poly(alkyne)s, aromatic hydrocarbons, aromatic hydrocarbon polymers and aliphatic hydrocarbons. Butane is a particularly suitable hydrocarbon which stimulates the growth of butane-utilizing bacteria. Remediation may occur in-situ or exsitu, and may occur under aerobic, anaerobic or dual aerobic/anaerobic conditions. Examples of applications include the remediation of heavy metals, the remediation of arsenic impacted surface water, groundwater and/or soil, the remediation of acid mine drainage, and the treatment of spent metal plating solutions.
摘要:
A non-invasive brain assessment monitor (10) is disclosed. An embodiment of the monitor includes a head-mounted brain sensor (18) which passively senses acoustic signals generated from pulsing blood flow through a patient's brain. A reference sensor (25) may be mounted at another location on the patient's body to sense an arterial pulse, and the signals from the brain sensor (18) and reference sensor (25) may be compared. Another embodiment includes transmitters (14, 16) which generate acoustic signals in the brain which are also detected by the brain sensor (18) . The brain assessment monitor (10) may be used to detect conditions such as head trauma, stroke and hemmorhage.
摘要:
A test kit for detecting viral or biochemical infections is disclosed comprising a housing, at least one test well in the housing comprising a test material for detecting and indicating the presence of a virus, biochemical agent or antibodies in a test sample, and a control material adjacent the housing comprising a damage indicating material, a taggant material or a track and trace element. A method of detecting viral or biochemical infections using the test kit is also disclosed. The method includes contacting a test material with a test sample, and observing any change in appearance of the test material to determine the presence or absence of the virus, biochemical agent or antibodies.
摘要:
High ductility steel sheet products are disclosed that have controlled compositions that, in combination with controlled heating cycles, produce desirable microstructures and favorable mechanical properties including ultimate tensile strength of at least 1180 MPa, high ductility, hole expansion, bendability and formability. Steel compositions include controlled amounts of carbon, manganese, silicon, chromium, molybdenum and aluminum. Rolled sheets are subjected to a thermal cycle including a heating stage followed by quenching to below the martensite-start temperature and aging.
摘要:
Controlled clutchless shifting of multi-ratio geared electronic shift transmissions coupled directly to the electrical prime mover of a vehicle are disclosed. The adaptive control of electrically shifted manual transmissions incorporated into power-split series electric hybrid heavy vehicles operating over heavy duty drive cycles utilizes a direct coupling assembly that enables bi-directional energy transfer and power transport. An electronic shift transmission provides power amplifying or de-amplifying bi-directional intelligently controlled valve or pathway for available terrain potential or kinetic energy of a rolling mass of a vehicle, while retaining the original function of a transmission by increasing or decreasing mechanical rotating energy of the propulsion power to the rear wheels of a vehicle.
摘要:
Track and trace packaging is disclosed which may also be damage indicating. Track and trace functionality may be incorporated on, in or near the packaging at various stages of a supply chain. A damage indicating material can be incorporated into a variety of packaging substrates, which may change color when exposed to oxygen, excessive heat and/or excessive pressure. An anti-counterfeiting taggant material may be used to provide track and trace capabilities. Exemplary products with which the present track and trace packaging may be used include packaged condoms, food and beverages, pharmaceuticals, cannabis and the like.
