Title: Condition detection and indicating means for a storage battery
Inventor: KHOO TENG CHEOK
IPC: G01R31/36
Filed: 2004-01-21
Abstract: There is disclosed a storage battery which is capable of self-monitoring by detecting and indicating the actual capacity and the expected remaining life-span of the battery, the condition of its charging system and the discharge level. The battery is provided with an integrally assembled detection and indicating means which measure the actual potential across its terminal (indicative of the state of charge of the battery) and the internal resistance of the battery (indicative of its health). The expected remaining life-span of the battery is derived from the calculation of current from these measurements. The battery is assembled to include a casing (2), a cover (3) and a capacity detection and indicating means. The detection and indicating means consist of an electronic circuit that measures the electromotive force and the internal resistance of the battery and indicate the same on a display means (9). The display means is adapted to exhibit whether the battery is in good working condition or otherwise during engine off or whether the charging system of the vehicle is in good working condition during engine in operation.  Further, it could also monitor potential leakage presence in its electrical system.

Title: Radiation shield for a safety syringe having a needle sheath
Inventor: BESING QUENT
IPC: A61M5/178
Filed: 2004-04-08
Abstract: A syringe injection shield (100) is formed primarily from a radio-opaque substance, such as tungsten, to shield medical personnel from exposure to radiation during administration of radiopharmaceuticals to patients. Safety syringes (22) typically have a needle sheath that can be positioned around a needle (24) after administration of the radiopharmaceutical. The syringe injection shield of the present invention allows medical personnel to make the syringe "safe" before the used syringe is removed from the syringe injection shield. The syringe is safe when the needle sheath is positioned and locked in place around the needle to reduce the risk of needle stick. The syringe injection shield includes a toggle element (110) that can assume four different positions as follows: neutral; ready; hold; and release.

Title: On-line compositional allocation
Inventor: MELBO HALLGEIR
IPC: E21B47/12
Filed: 2004-05-07
Abstract: A method and a system to provide allocation of mixed flows back to individual sources in an oil and/or gas production system. The method is independent of sub sea on-line measurements. Instead the method uses comparably inexpensive topside equipment for compositional allocation of the flows. The method comprises the use of an on-line allocation algorithm. The method is suitable where improved reliability of flow allocation back to wells and reservoirs is needed. The allocated flow may be used to calculate and estimate the remaining volumes in a reservoir.

Patent CA-2525662-A1 (CA)
Inventor: GIAN MICHAEL
IPC: G05D11/02
Filed: 1996-07-25
Abstract: A system for applying accurately metered, minute quantities of concentrated additives from bulk sources of supply to successive masses of material presented for treatment includes a pass-through chamber within which separate streams of a liquid carrier and the additive substance are merged together. As the liquid carrier passes through the chamber, the additive, in either dry or liquid form, is likewise directed into the chamber in a metered flow to incrementally combine with the liquid stream and form the combined product. A suction pump at the downstream end of the chamber draws the prepared product out of the chamber and advances it toward an ultimate delivery site. The carrier liquid is prevented from accumulating into a pool within the chamber by the suction pump that cooperates with the upright orientation of the chamber to cause the carrier liquid to swirl smoothly through the chamber. A suction vortex may be created as the product exits the chamber, within which vortex the additive may be directed so as to complete its entrainment with the carrier without causing turbulence. The system can be easily flushed with the liquid carrier after each batch and then dried with an optional air blower.

Title: Method and apparatus for measuring parameters of a fluid flowing within a pipe using a configurable array of sensors
Inventor: DAVIS MICHAEL A
IPC: G01F1/7082
Filed: 2004-08-02
Abstract: An apparatus for measuring at least one parameter associated with a fluid flowing within a pipe includes a spatial array of pressure sensors disposed at different axial locations x1... xN along the pipe. Each of the pressure sensors provides a pressure signal P(t) indicative of unsteady pressure within the pipe at a corresponding axial location of the pipe. A signal processor receives the pressure signals from each of the pressure sensors and determines the parameter of the fluid using pressure signals from selected ones of the pressure sensors. By selecting different pressure sensors, the signal processor can configure the array to meet different criteria. In one embodiment, the array of pressure sensors may be formed on a single sheet of polyvinylidene fluoride (PVDF) that is wrapped around at least a portion of an outer surface of the pipe. This arrangement allows a large number of pressure sensors to be quickly and economically installed.
