Abstract: ABSTRACT OF THE DISCLOSURE This device provides electrical characteristics which are the analog of the thermal characteristics of a device whose thermal behaviour is being monitored.  This device utilizes a resistor-capacitor network to provide an analog circuit which equates the thermal conditions in the rotor of a dynamoelectric machine to the voltage build-up in the capacitor of the analog circuit.  In order to keep the size of the capacitor within reasonable limits, a sampling technique is used to connect the capacitor into the electrical circuit for short periods only.  This has the effect of multiplying the size of the capacitor.

Abstract: ABSTRACT OF THE DISCLOSURE        The present invention relates to an arrangement for controlling fluid-flow through an aperture.       In one embodiment, the flow control arrangement, which may be used in association with a window to control the flow of ventilating air, comprises a strip brush composed of an array of resilient filaments firmily mounted at their root region.  The free end region of the filaments define, with a fixed flange, the effective area or width of an aperture for the passage of ventilating air.  Variations in the strength of the air flow incident to the array of filaments causes changes in the degree of deflection of the filaments, thus altering the effective width of the aperture and controlling the air flow through the aperture.

Abstract: ABSTRACT OF THE DISCLOSURE           A sealed compound bearing consisting of an outer and an inner member movable relative to each other and between which are disposed load carrying annular members.          The load carrying annular members comprise a pair of elasto-meric rings held between the outer and inner members under compression, and a metallic ring insert disposed between and separating the two elastomeric rings.  A narrow clear-ance is provided between the peripheral surface of the metallic ring insert and the inner surface of the bearing outer member, and between the metallic ring inner surface and the inner member peripheral surface.  Normal loads are taken and absorbed by the elastomeric rings, while overloads and shock loads are taken by the metallic ring insert.  A non-clearance thin metallic sealing ring is disposed between each elastomeric ring and a corresponding side surface of the ring insert, pre-venting the material of the elastomeric ring from creeping into the spaces resulting from the clearance existing be-tween the ring insert and the outer and inner bearing members, and preventing introduction of dirt and contaminants into the clearance spaces.

Abstract: ABSTRACT           An improved method of hardening elongated steel pipe, to reduce or eliminate quench cracking, and to produce higher strength product from a given base material, comprises the steps of:  quenching the pipe from an initial elevated temperature higher than the austenite transformation temperature, by immersion in a liquid cooling medium; controlling the flow of liquid cooling medium to produce a substantially uniform rate of cooling as between the inside and outside surfaces of the pipes; and interrupting the quenching process and withdrawing the pipe from the liquid cooling medium, not later than when the pipe has reached a temperature in the vicinity of the martensite start temperature.  Following interruption of the quench process, the pipe may be promptly conveyed to a tempering furnace, without significant cooling, and tempered at a temperature higher than the martensite start temperature.  Alternatively, following interruption of the quenching process, the pipe may be further cooled at a sufficiently slow and uniform rate to avoid quench cracking, and may subsequently be tempered in conventional fashion, if desired.

Abstract: Abstract The acoustic wave generated by sudden thermal stress is used to obtain information non-invasively on the composition and structure of the stressed body.  One or more acoustic transducers (1 and 1') are coupled with the surface of the body to inter-cept the acoustic wave and generate a corresponding electrical signal.  The sudden thermal stress is induced by a pulse of radiation which deposits energy causing a rapid, but very small, rise of temperature.  The radiation may be ionizing radiation, such as high energy electrons, photons (x-rays), neutrons, or other charged particles. The radiation may also be non-ionizing radiation, such as RF(2) and microwave electromagnetic radiation (3) and ultrasonic radiation (4).  The electrical signal from the acoustic transducer (1) is amplified (5) and supplied to a digitizer (6), which provides a continuous stream of digital words corresponding to samples of the amplified signal. Because in most situations of practical interest the SJN ratio of a single pulse is much less than unity, it is necessary to signal-average the signals from many successive pulses.  This is accomplished with a minicomputer or data processor (8) suitably interfaced (7) with the digitizer.  The resulting data can then be suitably displayed as an image on a CRT display (9) or plotted or numerically printed out.

Abstract: ABSTRACT   A threaded insert plug for at least temporarily closing an opening in an internally threaded member. The plug member comprises a right circular cylinder closed at the lower end thereof. The closing surface includes an upstanding central portion proportioned to permit the application of a wrench and may include a screwdriver slot on an upper surface. The interior of the cylinder includes critically positioned projections and/or depressions which permits use of a lever having an end positioned against the projection or depression and a mid-portion against at least part of the upstanding central portion to permit the production of a turning torque. The surface irregularitiesmay be configured and positioned to permit engagement with a suitable wrench. The walls of the plug may have generally uniform thickness thereby providing an economical and minimum weight plug. The upper surface of the upstanding central portion rises no further than the plane including the upper limit of theplug member. This facilitates use of the plug with a coupling to provide a penetration in a poured concrete wall or any other application where flush mounting is expedient.
