Title: Fault-tolerant chemical injection system for oil and gas wells
Inventor: WATSON RICHARD R
IPC: E21B33/068
Filed: 2009-03-17
Abstract: A metering body 212 for a chemical injection system comprises a cylinder 214 and a free piston 222 having a pair of mechanically-actuated poppet valves (240 & 242) which may individually open to permit fluid to pass from one side of the free piston to the other. The free piston slides within a cylinder having cylinder heads 216 & 217 at opposing ends. Position sensors 238 and 240 and input/output ports 228 & 230 are provided in the cylinder heads. In a preferred embodiment, the poppet valves have actuators that extend beyond the opposing faces of the free piston. If one face of the piston moves to within a predetermined distance of a cylinder head, the actuator contacts the cylinder head and further movement of the piston causes the corresponding poppet valve to open, permitting fluid to flow through the piston. In this way, a fault-tolerant system may be implemented. If a power interruption or other failure of the controller occurs, the system will continue to supply fluid at the most recently selected flow rate. When power is restored (or the fault is corrected), the controller causes a valve to reverse the flow of fluid through the metering body and the spring-loaded poppet valve will close as the free piston moves away from the cylinder head.

Title: Determining DC-DC converter losses
Inventor: KELLY ANTHONY
IPC: G05F1/62
Filed: 2009-05-14
Abstract: A switching DC-DC converter having a switching circuit to convert an input voltage to an output voltage, such as a buck converter, has a control loop to control the switching circuit which can attempt to maintain the output voltage at a preset level. The control loop includes an auto zero loop to modify a feedback gain to reduce error in the control loop. The loss in the switching circuit is estimated from the value of the feedback gain. The estimated loss can be a power loss, a current loss or a voltage loss and be used to calculate input power and to select the most efficient mode of operation, such as the mode of phase operation including the optimum point for switchover between a single phase mode or dual phase mode in a two phase DC-DC power supply. The loss can also be used to tune an operating characteristic such as switching frequency and the degree of overlap between complementary switches; and be sent to an external device, possibly to control the voltage on a supply bus supplying an input voltage to the converter. DC-DC converter power losses can be calculated without a measurement of input current.

Title: An improved rubber or elastic thread and an improved method of making or producing elastic threads of rubber or the like
IPC: B29D99/00
Filed: 1934-04-06
Abstract: Latex and coagulant are brought together to form a thread of coagulum which is stretched while coagulation is not yet completed, the period of stretching being so regulated that the skin does not become fully coagulated before the stretching is finished, and the coagulation is subsequently completed so that complete setting of the skin occurs after the stretching has taken place.  Thus, a thread of coagulum produced by extrusion or other methods is passed directly from the coagulating zone over two or more rollers, or belts or blankets, rotating or moving at progressively increasing speeds.  During stretching the thread may be subjected to coagulating influences and passed through drying or anti-adhesive material.  The thread may be finally wound on to a pirn and vulcanized thereon.  Specifications 214,615, 333,005, [both in Class 70], 375,244 and 388,216 are referred to.
