Abstract: IMPROVEMENTS IN FIREPLACE WOOD CUTTING MACHINE            Abstract of the Disclosure In a first embodiment of the invention an elon-gated support frame is provided including inlet and outlet ends.  The inlet end includes an inclined loading conveyor and a winch is supported by an upper portion of the frame and has a drag cable connected thereto for length-wise winching logs toward the loading conveyor.  Shear structure is supported from the frame adjacent the upper end of the loading conveyor whereby end portions of logs being advanced along the conveyor may be cut therefrom and an elongated trough is provided for receiving cut log end portions.  One end of the trough includes stationary wedge structure and a power ram is provided for forcing cut log portions along the trough into engagement with the wedge structure, whereby the cut log portions may be split into multiple log sections.  An inclined discharge conveyor is positioned to receive the multiple log sections from the wedge structure and is operative to elevate the logs to an elevated discharge end of the discharge conveyor for gravity discharge therefrom into a suitable receptacle.  In a sec-ond embodiment of the invention, the wedge structure is displaced laterally of the shear structure and a ramp is provided downstream of the shear structure for displacing the sheared log portion and positioning it for splitting.          In this embodiment the wedge structure translates, rather than being fixed, between a retracted position which is upstream of the shear structure and a cutting position which is downstream of the shear structure.  When the log portion is positioned for splitting after it has been sheared it is restrained by a backing plate and the wedge structure is forced through it rather than it being forced through a stationary wedge.  Therefore, the machine can be made shorter and more compact than in the first embodiment.

Abstract: ABSTRACT OF THE DISCLOSURE      A pressure sensor for use in measuring pressures in liquid at high temperatures, especially such as liquid sodium or liquid potassium, comprises a soft diaphragm in contact with the liquid.  The soft diaphragm is coupled mechanically to a stiff diaphragm.  Pressure is measured by measuring the displacement of both diaphragms, typically by measuring the capacitance between the stiff diaphragm and a fixed plate when the stiff diaphragm is deflected in response to the measured pressure through mecnanical coupling from the soft diaphragm.  Absolute calibration is achieved by admitting gas under pressure to the region between diaphragms and to the region between the stiff diaphragm and the fixed plate, breaking the coupling between the soft and stiff diaphragms. The apparatus can be cali-brated rapidly and absolutely.

Abstract: A B S T R A C T         An improved, thin walled fastener for retaining studs, rods, or the like is provided.  The fastener is of the push-on type comprising a one-piece, generally thin, stamped sheet metal resilient body defining a generally centrally located stud retaining aperture for receipt and retention of studs, rods or the like.  The body is preferably generally frusto-conical or dome shaped in cross section.  The fastener is formed by punching or shearing a hole in a blank and then forming a generally dome shaped impression in the blank, the impression being generally coaxial with the axis of the punched hole.  The required trans-verse extensions of the body are minimized by the utilization of the relatively smooth continuous edge of the punched hole rather than the burred edge of a punched hole as the stud retaining edge of the fastener stud retaining aperture.

Abstract: Title of Invention SYSTEM FOR DETECTING POSITION OF GAUGE POINTER     Abstract A system is disclosed for detecting the position of the pointer of a gauge.  The system includes a stationary light source which is positioned adjacent the pointer.  A lens receives the light from the light source and redirects the light in at least one elongated light beam directed toward the pointer.  In the preferred embodiment, the light source is located along the pointer's axis of rotation and the lens bends the light rays 90° to form at least one arcuate light beam.  A plurality of elongated light beams can be used and variations of different shapes of light beams can readily be used by so designing the lens means.  A light sensitive detector is positionable in the gauge itself and is movable along a guided path on the opposite side of the pointer than is the light source. The guided path generally follows the particular shape of light beams that is directed toward the needle.  The function of the light detector is to sense, and provide some signal when the pointer pas-ses across the sensor, thereby substantially reducing the amount of light directed toward the sensor.  In this manner the detector sig-nals the position of the pointer.  The sensor may be moved within limits to an infinite number of positions along the elongated light beam by conveniently located knobs outside the gauge.  The operator thus can, by simply turning a knob, adjust a sensor to a desired po-sition and the sensor will detect when the gauge pointer passes or remains at that position.

Abstract: ABSTRACT OF THE DISCLOSURE                An ultrasonic probe is described, for use in a system for measuring the length of a reflecting anomaly in a workpiece.  The probe operates to yield an output signal having elements therein directly related to the length of that anomaly, typically, a crack.  The probe comprises a first transducer having a face for transmitting an incident beam of ultrasonic irradiation.  A second transducer is provided, acous-tically non-coupled to the first transducer, and having a face for receiv-ing a portion of the incident beam reflected from an extremity of the anomaly.  Directing means are connected to at least one of the transducers, causing the transducers to be oriented in a manner such that orthogonal projections of the transducer faces intersect to define a depth of field in which the extremity of the anomaly is locatable.  A probe housing supports the transucers and the directing means.  The housing also includes signal conducting means connectible to an ultrasonic source to drive the transmitting transducer, and to signal processing and displaying apparatus for processing the output signal and providing a read-out of the length of the anomaly.  In a preferred embodiment, the directing means comprises two similar prisms joined together physically but non-coupled acoustically, with each prism serving to mount a related one of the transducers thereon.       In a still more preferred form, the transmitting transducer is of lead zirconate titanate, find the receiving transducer is of lead meta niobate.  The two transducer heads are provided in the one ultrasonic probe and measures the length of the reflecting anomaly from a generally "end-on" orientation.

Abstract: Title: PROCESS FOR FLUE GAS DESULFURIZATION.            Abstract of the disclosure: SO2 is absorbed from hot flue gas by spray drying a Ca(OH)2-containing suspension in the flue gas. Fly ash is left in the flue gas which is to be treated in the spray absorption process, and the powder which is produced by the spray absorption process and which consequently contains the fly ash and partly reacted Ca(OH)2 is partially recycled. Operation is controlled to obtain a temperature of the flue gas after the treatment which is 8-40°C above the saturation temperature of the flue gas at this stage. The process leads to optimum use of the Ca(OH)2 used as absorbant and of the neutralization power inherent in the fly ash. Problems due to sedimentation of the absorbant before its atomization are avoided.
