Abstract: The invention relates to a separator, which is particularly useful for separating cellular matter. The separator utilises the phenomenon  known as dielectrophoresis (DEP). A DEP force effects a particle suspended in a medium. The particle experiences a force in an alternating electric field. The force is proportional to, amongst other things, the electrical properties of the supporting medium and the particle and the frequency of the electric field. The separator, of the present invention. comprises a chamber (10) and a plurality of electrodes (12) disposed in the chamber (10). An electric field established across electrodes subjects some of the particles to a stronger force than others such that they are confined within the chamber. Particles which are not confined are removed from the chamber by the supporting medium which is preferably urged through the chamber. Valves (101 and 202) are provided on exhausts of the chamber. The invention is able to separate two different particles continuously.     ,

Title: Double-delta turnstile antenna
Inventor: PODGER JAMES STANLEY
IPC: H01Q1/36
Filed: 1996-03-04
Granted: 2000-01-11
Abstract: This antenna has two sets of conductors. Each set is two coplanar triangles with a corner from each triangle at the centre and with the two triangle sides opposite those corners being positioned parallel to each other. The planes of the two sets are perpendicular to each other, with the junction of the two planes being close to the lines through the centres of the parallel sides and the centers of the sets. If the two structures were positioned so that the junction of the two planes was vertical and if they were fed so that the currents in corresponding parts were equal in amplitude and different in phase by 90 degrees, a horizontally polarized omnidirectional radiation pattern would be obtained. Such an omnidirectional antenna would have more gain than a turnstile array of half-wave dipoles with less wind resistance than a Masters super turnstile antenna.

Abstract: An axial flow fan primarily for use in harsh and/or corrosive environments such as agricultural barns has a one-piece plastic moulded housing which defines an air flow passageway, and a direct drive fan assembly mounted in the air flow passageway by means of a novel motor mount. The mount includes at least three radially disposed support arms of equal length which maintain the fan assembly in the center of the air flow opening despite distortions in the housing that might occur for example due to temperature changes. Each support arm is a thin and flat plate disposed edge on to the air flow so as to minimize resistance. The air flow opening is smoothly contoured to define a convergent conical inlet section and a divergent conical outlet section for improved efficiency of air flow.

Title: Skin substitute using marine organisms
Inventor: TAKAI MITSUO
IPC: A61F2/10
Filed: 1996-06-25
Granted: 2000-06-06
Abstract: There is provided a skin substitute that can suitably be used for covering the surface of a damaged skin area which is typically a wound produced by a traumatic local loss of the skin of the human body as a result of a burn or some other cause of damage. It is a skin substitute of a laminate comprising a squid chitin sheet and a fish skin collagen coat layer, which may be a salmon skin collagen coat layer. Such a skin substitute effectively exploits the suppleness and the effect of proving an environment for encouraging the production of lysozyme and defending the wound of squid chitin and, at the same time, compensate the disadvan-tage of poor adhesion of fibroblast cells that operate for curing the wound.  Additionally, the fibroblast cells adhering to a laminate of a squid chitin sheet and a fish skin collagen coat layer showed a normal cell proliferation curve without any delayed initial rising phase to prove the former more satisfactory that cannot be expected from a laminate comprising a calf skin collagen coat layer.  Finally, a DNA labeling index substantially equal to that of fibroblast cells of  normal human skin was observed.

Up on occurrence of an interrupt signal, excecution of the first routine is halted. Also, the status of the computer at the time the inter rupt signal occured is stored in memory. Thereafter, a second routine (an interrupt routine) is executed to access the data stored in the data b uffer. Once the data is accessed, the status of the computer is restored in accordance with the previously stored computer status informati on. Lastly, the first stored routine is restarted at a position therein at which the first routine was interrupted to execute the second routine.

Abstract: A method for determining oil saturation in an earth formation penetrated by a wellbore. Measurements of relative amounts of carbon and oxygen are made by spectral analysis of neutron-induced inelastic gamma rays detected from the earth formation at spaced apart locations. The method includes calculating an apparent oil holdup in the wellbore at each of the spaced apart locations from the relative amounts of carbon and oxygen. A corrected oil holdup is calculated in the wellbore from differences between the apparent holdups determined at each of the spaced apart locations. An apparent oil saturation in the formation is determined at each of the spaced apart locations from the relative amounts of carbon and oxygen and the corrected oil holdup. A corrected formation oil saturation is determined from differences between the apparent oil saturations at each of the spaced apart locations. In a preferred embodiment, the apparent oil holdups and apparent oil saturations are determined by comparing the measured carbon and oxygen amounts with empirical relationships of the relative amounts of carbon and oxygen with respect to known values of oil holdup and oil saturation for various mineral compositions and porosity values of the earth formation.

Abstract: A data transmission system for a vehicle includes a plurality of control systems installed on the vehicle, and a network bus connecting the plurality of control systems with each other for circulating a transmission right through the plurality of control systems to thereby perform transmission of a message between the plurality of control systems.  According to a first aspect, each of the control systems starts transmitting data when it is detected that the transmission right is not generated or lost from the system, and continues transmitting the data when no collision of data transmitted from the present control system with data transmitted from the rest of the plurality of control systems, or when by mediation for avoiding the collision is detected, it is determined to continue data transmission.  According to a second aspect, the maximum number of times of retransmission to be permitted is determined according to a type of failure in transmission identified, and the retransmission is performed so long as the number times of retransmission of the data does not exceed the maximum number of times of retransmission to be permitted.  According to a fourth aspect, the message comprises a first response field for receiving a first acknowledging response output from a control system having received the transmission right, and a second response field for receiving a second acknowledging response output from a control system having received data.
