Abstract: ABSTRACT OF THE DISCLOSURE            An apparatus and method for improving the combustion process of an internal combustion engine is disclosed.  A pre-chamber containing a combustible mixture is designed to generate a torch eminating therefrom upon ignition; the torch is con-trolled to extend and penetrate deeply into the main combustion at a predetermined orientation without contact with the chamber walls.  The swirling flame front of the sustained torch produces superior mixing with the unburned combustible mixture in the main combustion, particularly of a rotary engine.  The prechamber is located outside the epitrochoid chamber of the rotary engine; in a nonstratified charge mode of this invention, the prechamber serves to receive n portion of the main chamber inducted charge during the compression cycle, which may lean and difficult to ignite in the main chamber.  In the prechamber, concentrated hot walls and a localized spark facilitate ready ignition, which in turn permits generation of a torch therefrom.           A scavenging system and method is disclosed which serves to drive residual gas elements from the prechamber after the completion of each combustion cycle; the scavenging apparatus may be operated with an independent gas supply, a supply derived from the carburetor or intake of the engine, or from the inducted mixture within the main chamber.  The scavenging system may have fuel enrichment to create a predetermined charge stratifi-cation.           A fuel injection system and method is disclosed which serves to augment or act as the sole prechamber charge.           Prechamber design, chamber shape, compression ratios and engine controls are arranged to reduce combustion heat losses and selected emission constituents.

Abstract: INTERRUPTER SWITCH ARRANGEMENT ABSTRACT: Disclosed is a switch suitable for use in power systems. The switch is of the vertical break type, having two stationary support insulators and one reciprocatory, insulative push rod, wherein movement of a switch blade takes place in a plane which also includes the insulators and the push rod. The two insulators are mounted on a base, one insulator sup-porting a switch blade hinge assembly, and the other insulator supporting a contact assembly for the switch blade. A novel linkage mounted to the hinge assembly connects the blade to the push rod and permits at least 90° of movement of the blade without adversely affect-ing dielectric clearances between the push rod and the insulators. The insulators remain stationary when the switch operates, only the push rod and the novel link-age moving to provide motive force to the blade. The push rod may be reciprocated by interconnection to a rotatable shaft via a lever. The shaft may be con-nected to an operating pipe reciprocated by a remote operator for rotation therewith. After the switch is open, the novel linkage permits the push rod and the lever to form an over-center toggle which, together with the more than 90° opening of the blade, prevents the blade from inadvertently moving toward engagement with the stationary contact as a result of external forces such as wind, etc. The switch and the linkage are usable in single pole and polyphase switches in a variety of configurations.

Abstract: ABSTRACT OF THE DISCLOSURE             A dump truck having a telescoping container body which is initially telescoped to a reduced length to discharge a portion of the load and thereafter elevated to discharge the remainder of the load in the manner of a conventional dump truck.          The front section of the container body is longer than the back section so that a portion of the front section will project rear-wardly from the back section when the sections are located in the retracted position whereby the centre of gravity of the telescoped sections is more than that of the back section alone when the telescoped sections are elevated for dumping.  The drive mechanism for driving the front and back section relative to one another consists of a rack mounted on the front section and a reciprocating drive means mounted on the truck.  A pawl is mounted on the drive mechanism and engages the rack to selectively push or pull the front section as required.  The length of the stroke of the drive mechanism is substantially shorter than the total length of movement of the sections between the extended and retracted positions thereof.

Abstract: LOW-COST BUT ACCURATE RADIOACTIVE LOGGING FOR  DETERMINING WATER SATURATIONS IN A RESERVOIR                ABSTRACT OF THE DISCLOSURE     A method is disclosed for determining water saturation in a petroleum reservoir using logging signals in-directly related to the abundances of oxygen nuclei in the reservoir rock.  The first step of the invention is to record a log sensitive to the abundance of oxygen nuclei, after the region surrounding the well bore is caused to have fluid saturations representative of the bulk of the reservoir.          A purposeful change is then made in the fluid saturations in the region surrounding the well bore by injecting a liquid capable of displacing substantially all of the original fluids.  The log is recorded a second time.  The displacing fluid is then itself displaced by brine, and a third log is recorded.  Water saturation is then determined from differences between the logs and from known fractional volume oxygen con-tents of the reservoir brine and the first injected liquid.          It is not necessary that the log responses be independent of the material in the borehole, the casing, the casing cement, or the reservoir rock.  It is only necessary that changes in formation content cause proportional changes in log responses.

The butterfly valve is fabricated by first positioning the disc halves on opposite sides of the stem in opposed face-to-face relationship and securing the disc halves to the stem. The resulting subassembly is then positioned in a mold having a cavity arranged to define the valve body and a pair of cores which clampingly engage the disc and define the flow passage.  A molten thermoplastic material is then injected into the mold cavity to form the valve body in a finished form.

Abstract: ABSTRACT OF THE INVENTION         A method and apparatus is disclosed for automati-cally maintaining a transducing head on the proper track and is particularly adapted for a helical scan recording and reproducing apparatus that is capable of providing special motion effects, such as slow, still and East motion, and other effects.  The apparatus is of the type which utilizes transverse positioning of the transducing head to accura-tely follow a track during reproducing and, at the comple-tion of the track, to properly position the head in position to either play the next adjacent successive track, replay the same track or play another track so that the appropriate special motion effect is achieved.  To provide accurate head tracking, a small oscillatory motion (dither) is applied to the head to cause it to vibrate laterally between two limits relative to the track.  This causes amplitude modulation of the reproduced signal, which is in the form of an RF envelope of frequency modulated carrier.        A feedback servo circuit is responsive to the amplitude modulated reproduced signal to provide continuous adjust-ment of the transducing head position so as to maintain the magnetic head in optimum reproduce relationship with respect to the track.  An automatically calibrated RF envelope detector circuit includes a reference level setting feedback loop which takes a reference level from the input signal to the detector circuit to control the gain of the latter circuit regardless of tape RF level differences, operating conditions, component characteristics, etc.
