Abstract: A variable geometry turbine and active wastegate are provided in combination along with independent control of the variable geometry turbine and wastegate valve so as to independently control exhaust gas recirculation flow and air flow in an internal combustion engine. Such independent control of exhaust gas recirculation flow and air flow in an internal combustion engine is achieved by providing a system for exhaust gas recirculation including an intake air manifold, an exhaust manifold, an exhaust gas recirculation passage providing fluid communication between the exhaust manifold and the intake air manifold, a variable geometry turbine positioned downstream of the exhaust manifold, and a waste gate passage providing fluid communication between the exhaust gas manifold and a point downstream of the variable geometry turbine.

Abstract: An improved method and system for automatically continuously removing an engine's used lubricating oil and injecting the used oil into the engine's fuel system throughout operation based on engine operating conditions is disclosed. The present system includes a lube oil replacement pump system for injecting small amounts of used lube oil into the engine's fuel system and recycling controlled quantities of removed used oil into the engine's lube oil system. The process periodically determines an engine operating severity value, i.e. fuel consumption value, for an interval of engine operation and calculates a base line quantity of oil for injection based on the current fuel consumption of the engine during the current interval. The lube oil pump system may be in the form of a compact, unitized lube oil replacement pump assembly integrating the various components of the system.

Abstract: An improved wastegated turbocharger including ejector nozzles such that the bypassed exhaust flow re-enters the main exhaust flow at a predetermined pitch angle and yaw angle so as to create a drop in turbine back pressure. The exhaust gas turbocharger includes a turbine housing having a turbine chamber, an exhaust housing portion, and an exhaust gas inlet to said turbine chamber wherein a turbine wheel is rotatably mounted in the turbine chamber and is rotatably responsive to exhaust gas flow from the exhaust gas inlet. In one embodiment, an outlet insert is provided which is rigidly attached to the exhaust housing portion and extends toward the turbine chamber thereby defining a bypass chamber and providing an exhaust gas outlet. A bypass flow passage which fluidly connects the exhaust gas inlet with the bypass chamber is also provided. The outlet insert includes a plurality of ejector nozzles for directing exhaust flow from the bypass chamber to the exhaust gas outlet.

Abstract: A tamper indicator includes a collar which can be positioned to be circumambient a connection nut on a gas meter. The collar includes two portions which are interlocked by snap-catches which are located inside a locked collar. The collar portions are formed of frangible material and can include lines of weakening. Once in place, the collar cannot be removed without breaking it, and once broken cannot be repaired so that an indication is provided that the encircled connection nut may have been tampered with.

Abstract: Apparatus for converting an enclosable food cooker having a food supporting surface into a food smoker which can be advantageously used to smoke food at a very slow rate without significant dehydration or loss of natural juices. The apparatus includes an open topped container or pan containing a water filled, heat absorption cavity and suspension means, such as upstanding hooks, for detachably suspending the container or pan from the food supporting surface. A method for employing the apparatus in a conventional home charcoal grill is disclosed.

Abstract: This invention relates to a medical clamp for controllably occluding extremely small body vessels such as blood vessels within the intracranial or intraspinal areas of the human body. The disclosed clamp is preferably formed from a U-shaped unitary body of transparent, resilient elastomeric biologically inert material such as Tygon or Silastic wherein the leg members of the U-shaped body are controllably brought together to occlude a vessel placed therebetween by means of a flexible line or spring. Several embodiments are disclosed illustrating various expedients for securing the flexible line such as a sliding friction device or latch plate, and for operating and securing the string mechanism. All embodiments include means for measuring and detecting the termination of fluid flow through a vessel being occluded. Such measuring or detecting means permit the use of only that amount of pressure and no more than is necessary to cause vessel occlusion.

Abstract: Method and apparatus is disclosed for editing and mounting segments of recording tape containing prerecorded visual information, such as segments of an electrocardiogram (ECG) recording tape. The disclosed apparatus includes an editor for storing and feeding the tape past a window through which the tape may be viewed. Upon detection of a desired tape segment, the tape is halted and marked with the aid of a scale mounted adjacent the window opening. Thereafter, the tape is severed at each mark to form a segment having a longitudinal length corresponding to the particular type of information contained on the severed tape segment. In the preferred embodiment, the apparatus is adapted to process electrocardiogrphic recording tape and the editor scale includes a zero mark and a plurality of index marks spaced from the zero mark by distances corresponding to the desired longitudinal length of various groups of lead segments such as ECG leads I-III, V.sub.1 -V.sub.6, aVR, aVL and aVF.
