Abstract: Abstract of the Disclosure A velocity transducer for converting linear mechanical motion to an electrical signal.  A stationary permanent magnet is supported within and spaced from an iron pole piece assembly which forms a closed path around the magnet.  The pole piece assembly has a pair of linear pole piece segments which extend in parallel on opposite sides of the magnet, spaced apart from the north and south pole faces of the magnet, respectively.  A movable (i.e. slidable) coil is wound around each such linear pole piece.  The two coils are series-connected and oppositely wound with respect to the flux pro-duced by the magnet.  Noise signals induced in the coils subtract from each other and substantially cancel, but motion-related signals add.

Abstract: ENERGY CONSERVATION BY IMPROVED CONTROL OF BULK   POWER TRANSFERS ON INTERCONNECTED SYSTEMS     Abstract of the Disclosure This invention introduces the concept that on an interconnected electric power system, the area-caused com-ponents of memory parameters system time deviation and the total inadvertent interchange of each constitutent control area are separable and measurable.  Methods and means are disclosed for separating each of the components and deter-mining its magnitude, utilizing known or measurable para-meters, thereby providing new long-desired area memory parameters which are precise measures of the control per-formance of each area.  The portion of system time deviation and the portion, designated primary inadvertent, of total area inadvertent interchange caused by an area's own regu-lating deficiencies, and the portion, designated secondary inadvertent, of total area inadvertent interchange caused by regulating deficiencies of each remote area, are identified.        Certain of the components are then utilized in their re-spective areas to provide unilateral simultaneous corrective control of said area's component of system time deviation, said area's primary component of area inadvertent interchange, and the secondary inadvertent components of area inadvertent inter-change  of all remote areas caused by the regulating deficiencies of said area, doing so more effectively, more equitably and more economically than is possible with prevailing conventional control techniques.

Abstract: ABSTRACT OF THE DISCLOSURE        A method of testing a product for the detection of the presence therein of a defect such as a void or an inclusion, comprises cutting the product and examining the resultant noise for the presence therein of an acoustic component representative of the presence of the inclusion.  The method is applied to the processing of metal into slabs, bars, rods, wire strip etc., where the ends must be cropped to remove defective material, specifically to the continuous processing of strip metal where metal strips are joined continuously end-to-end, and where the ends of each strip as rolled may include undesired inclusions such as slag.  A leading end piece is cropped by a shear, and the cropping of such pieces is continued until the testing method shows that the material at the place of the cut is free of the undesired inclusions.  Apparatus for carrying out the method comprises an acoustic detector which is disposed as close as possible to the cutter to detect the noise of cutting, a suitable amplifier and means for examining the signal to detect therein an acoustic component representative of a defect in the material.
