Abstract: ABSTRACT OF THE DISCLOSURE   Apparatus for detecting flaws in the threaded end of a ferromagnetic pipe is disclosed.  The apparatus comprises means for applying a magnetic force to produce a field generally axially through the threaded end of the pipe, first and second means adjacent successive crests of a thread for sensing a generally radial magnetic field and generating a first and second signal corresponding to the sensed magnetic fields, and means for differentially connecting the signals generated by said first and second sensing means, whereby a differential output signal is produced in response to a flaw between the crests of the thread being inspected. The apparatus also comprises means for helically rotating said sensing means to follow a path corresponding to the threads of the pipe, whereby the first and second signals vary with time.   A method for detecting flaws in the threaded end of g ferromagnetic pipe is also disclosed.  The method comprises the steps of applying a magnetic force to produce a field generally axially through the threaded end of the pipe, sensing the radial magnetic field adjacent successive crests of a thread of the pipe, generating first and second signals corresponding to the sensed magnetic fields, and differentially connecting the first and second signals.

Abstract: Abstract of the Disclosure A positioning reel for suspending a body, such as a lightweight tool, at any vertical position within the limits of the suspension cord length is disclosed. An adjusting screw which regulates a clutch-type tensioning brake permits the supporting force of the positioning reel to be set to equalize the weight of the suspended body such that little effort is required to lower the suspended body.  With the downward external positioning force removed from the suspended body, it remains in its present position. The suspended body can be easily raised by applying an upward external force equal to slightly more than the weight of the suspended body.  When raising the suspended body, a clock type coil spring actuates a spool within the positioning reel for retracting the suspension cord.  A spring type override clutch permits reeling in the suspension cord while bypassing the tensioning brake. With the upward external force removed from the suspended body, it will again remain in its present position.

Abstract: ABSTRACT           A wick-type combustion apparatus for liquid fuels comprises: a pair of cylindrical walls extending vertically and opposed to each other with a gap; a cylindrical wick vertically movable as guided between and along the walls; a slit-form cylindrical fuel passage opening provided in the outer wall and adapted to be opened and closed by the descent and ascent, respectively, of the wick; a fuel trap chamber provided around the opening in communication therewith; and a cylindrical porous member vertically extending in the chamber.         A flame or flames remaining after the descent of the wick can be instantaneously blown out by a blast of an explosive combustion which occurs in the fuel trap chamber.  The porous member serves to reduce the amount of unburnt fuel used for the explosive combustion, so that an abnormal rise of flame or flames attendant with the explosion can be prevented.

Abstract: ABSTRACT OF THE DISCLOSURE           A forming shoe in a two-wire forming section of a paper making machine has a curved guiding surface which guides a joint run of the wires and web interposed therebetween over a curved path of travel wherein the web is dewatered under the effect of the pressure between the wires at least in a direction away from the forming shoe, the dewatering action being assisted by the curvature of the forming shoe due to centrifugal forces.          According to the invention, the length of the active portion of the forming shoe guiding surface, the surface quality or char-acteristics of the guiding surface and/or the radius of curva-ture of the guiding surface are adjustable so that web formation and the dewatering capacity of the forming shoe are controlled.          For this purpose one or more devices are coupled to the forming shoe by which the attitude and/or location thereof is adjus-table.  In one embodiment a device is provided between the frame of the forming section and that of the forming shoe for pivoting the forming shoe about a horizontal axis and/or displacing the forming shoe linearly with respect to the vertical and/or hori-zontal plane.

Abstract: ABSTRACT:           In an acoustic surface wave device employing an input and an output transducer 2, 3, and a multistrip coupler 5, the input and output tracks 11, 12, may have to be well separated to avoid unwanted acoustic energy transfer.  As a result, a significant loss can occur from the launching of acoustic energy from the interconnecting conductors of the msc.  In the improved device, the inter-connecting conductors 22 are given a spacing which is different from that of conductors 16, 17, in either track of the msc, and which must not be such as to launch any acoustic bulk waves within the frequency passband.  In a forward transfer msc different spacings can alternate as in Figure 4, and in a reflective msc the spacing can take the mean of the respective spacings of the coupled electrodes.

Abstract: ABSTRACT: "Infrared thermal detector."     An infrared thermal detector includes an infra-red thermal sensing element, a load resistor, and a vol-tage suPply means. The infrared thermal sensing element is a pyroelectric material whose electrical conductivity changes with temperature. The circuit and device para-meters are chosen such that the detector will have a flat frequency response over a broad band from dc (O Hertz) to a high frequency determined by the electronic time constant of the circuit. The detector thus has all the advantages of either a pyroelectric detector without a chopper, or a thermistor bolometer having a fast response time.

Abstract: ASSEMBLY CLIP FOR CEILING PANELS     Abstract of the Invention A multiple-purpose assembly clip for assembly of radiant ceiling panels and/or for flattening bowed radiant ceiling panels.  The clip uses a "twist-lock" technique.          In a first rotational position the clip is positioned over the panels.  The clip is then rotated about an axis perpen-dicular to the panels to a second rotational position to cause flanges on the clip to engage corresponding channels on the panels, thereby to urge adjacent panels together.          A "mirror image" clip is also used which twists in the opposite direction for locking.  The clip includes a central cut-out in a U-shaped member to form defined flanges and edges.  The cut-out is dimensioned so that as an alternative to use for locking adjacent panels (where the cut-out fits over edge connections of the panels) it can fit over a fluid-carrying tube mounted on the rear of the panel.  This permits the clip to be mounted wholly on one ceiling panel for flat-tening the panel.

Abstract: ABSTRACT           A flush valve connectable to a wall of a toilet tank is disclosed.  In one embodiment, there is a non-circular outlet formed in the bottom wall of the tank.  There is also a resilient seal bearing against an upper surface of the bottom wall, the seal surrounding the outlet and having a central bore aligned therewith.  A flush valve is provided having a housing that extends through the seal bore and outlet.  The housing also has an outwardly extending flange above the seal to trap the seal against the bottom wall, and a radially outwardly extending pro-jection below the bottom wall.  The housing is ro-tatable between a first position in which the pro-jection can pass vertically through the outlet, and a second position where the projection can catch un-der the bottom wall.  In another embodiment, there is a stop member formed on the outside of the housing below the resilient seal and above the projection, the stop member being suitable to interact with the periphery  of the outlet to limit rotation of the housing relative to the outlet.
