Filed: 2003-07-10
Abstract: By the utilizing of a slave cylinder working in coordination with a master cylinder, the slave cylinder both receives cool atmospheric air and receives hot, partially un-burnt exhaust gases from the master cylinder to create a second power- stroke in the slave cylinder. With the two coordinating cylinders, the entir e working process is from 0 to 810 degrees of revolution crankshaft. The maste r cylinder cycles work from 0 to 720 degrees of revolution and slave cylinder cycles work from 90 to 810 degrees of revolution. The master cylinder begins to intake air and fuel at 0 degree of revolution and slave cylinder begins to intake air at 90 degrees of revolution. There is an angle of 60 -120 degrees difference s between master and slave cylinder, where the slave cylinder is trailing the master.

IPC: G06F21/62
Filed: 2002-09-24
Abstract: The method and system (100) operates to provide client privacy on the Intern et when the client (102) requests content from a public application server (106 ). The method is well-suited to key management protocols that utilize the conce pt of tickets. The client (102) name or identity is encrypted in all key management messages where the client is requesting a ticket (TGS_REQ) for a specific application server (106). The key management messages are between t he client and a key distribution center (KDC) (104) and between the client (102 ) and the specific application server (106). The KDC (104) does not provide th e client (102) name or identity in the clear in such messages. This prevents t he client's identity from being linked with the content provided by the specifi c application server (106), which results in improved user privacy.

Filed: 2003-05-30
Abstract: The invention is a spatial light modulator (100) having selectively reflective deflectable micro mirror array (103) plates (202) fabricated from a first substrate (105). On another substrate there is addressing and control circuitry (106) for the micro mirror array (103), which allows the control circuitry (106) to control a voltage applied to selected electrodes (126) associated with the micro mirror plates (204). Typically, the control circuitry (106) includes a display control (108), line memory buffers (110), a pulse width modulation array (112), and inputs for video signals (120) and graphic signals (122). The mirror array substrate (105) further has a spacer support frame (210) and hinges (206), wherein when an electrostatic force is applied to the micro mirror array plates (204), the hinges attached thereto allow the mirror plates (204) to rotate relative to the spacer support frame (210). This rotation produces the angular deflection for the reflecting light in a selected direction. The first and second substrate are bonded together.
Patent CA-2473319-A1 (CA)
Inventor: PANIGRAHI SATYA
IPC: D06M13/10
Filed: 2004-07-09
Abstract: In recent years, the interest in using natural flax fibers in biocomposites has grown because They are lightweight, combustible, non-toxic, low cost and easy to recycle. On tue other hand, lack of good interfacial adhesion and poor resistance to moisture absorption make the use of natural fiber-reinforced composites less attractive. Chemical treatment of the fiber can stop the moisture absorption process, clean the fiber surface, chemically modify the surface or inerease the surface roughness. Short flax fibers, which were derived from Saskatchewan-grown flax straws, for use in fiber-reinforced composites. were mercerized and modified by silane treatment, benzoylation and peroxide treatment. Morphological and structural changes of the fibers were investigated by using scanning electron microscopy. The temperature variation method vas applied to obtain the melting point of treated flax fibers by the DSC  technique. The moisture absorption and bundle flax fiber tensile strength were also measured.   Natural flax fiber-reinforced composites have enhanced biodegradability, are lightweight, non-corrosive, temperature resistant and low environmental pollution. These advantages place natural fiber composites among the high performance composites having economic and environmental advantages. In the field of technical utilization of plant fibers, flax fiber-reinforced composites represent one of the most important areas, But high level of moisture absorption, poor wettability and insufficient adhesion between untreated fiber and the polymer matrix may lead to debanding with age. In order to improve the above qualities, various surface treatments of fibers like silane treatment, benzoylation and peroxide treatment were carried out which may result in improved mechanical performance of fiber composites. Short flax fibers were derived from Saskatchewan-grown flax straws, for use in fiber-reinforced composites Composites consisting of high-density polyethylene (HDPE) or linear low-density polyethylene (LLDPE) or HDPE/LLDPE, chemical treated fibers and additives were prepared by an extrusion process. The test samples were prepared by rotational molding. The effects of the different chemical treatments on the mechanical properties of natural fiber-reinforced composites were evaluated. The tensile fracture surfaces of the samples were characterized by scanning electron microscopy to determine whether the modified fiber-matrix interface had improved interfacial bonding.
