Abstract: ABSTRACT A switchgear apparatus having three switching gaps with contacts arranged thereacross for connecting three-phase electrical power to a consumer. Apparatus is described whereby a selected one of the switching gaps closes earlier than the other switching gaps during a closing cycle of the switchgear, and opens later than the other switching gaps during an opening cycle of the switchgear.  The contacts across the early closing and late opening gap experience only minimal contact burnoff, thereby permitting a substantially reduced volume of contact overlay material to be provided therefor. In addition, less expensive contact material may be utilized for this contact.

Abstract: ABSTRACT OF THE DISCLOSURE      A cardiogoniometry or vector cardiography  system wherein signals directly derived from the bioelectrical field are not directly processed as orthogonal data but are  instead  especially  orthogonalized  in  an  analog computing  network.   Orthogonalization  is  based  on  a derivation electrode configuration  space with  sloping sagittal and frontal planes.  The orthogonalized signals are processed in a cardiogoniometer and are also jointly recorded on a commercial electrocardiograph in parallel thereto.  All the represented data which can be used for diagnosis purposes are referenced to a biological zero line, which differs from the electrical neutral point.          The  cardiogoniometer  permits  a  vectorial  real  time measurement on the patient.

Abstract: Abstract Powder of essentially diboride of Group 4b metal with particle size substantially less than 5 µm is made by: (a) preparing a solution consisting essentially of Group 4b metal salt, soluble boron source and soluble carbon source in proportions for carbothermal reduction of the corresponding oxides of the metal and boron with carbon, (b) heating the solution to yield a dried and decomposed residue consisting essentially of very fine and intimate mixture of carbon and the oxides of the metal and boron, and (c) firing the residue up to and at temperature and for time to effect the carbothermal reaction of the residue to yield friable agglomerates primarily of the diboride which are very easily comminuted into powder of particles substantially less than 5 um size. Group 4b metal salt is replaced in part by salt of Group 5b, Group 6b and/or rare earth metal in order to yield corresponding boride of latter metal as sintering aid with Group 4b metal diboride in powder, especially as diboride solid solution. Latter complex diboride powder is suitable without hot pressing to close to theoretical density. The proportions of salt or salts, soluble boron source and soluble carbon source may be selected in additionally provide a minor boron carbon phase as sintering aid.

Abstract: ENERGY-EFFICIENT PROCESS FOR THE STRIPPING            OF GASES FROM LIQUIDS     Abstract of the Disclosure A process is disclosed for the recovery and reuse of the heat contained in the gas/vapor overhead mix-ture from a stripping column in which a noncondensable gas is stripped from a liquid solution by contacting the solu-tion with a hot vapor such as steam.  The steam or other vapor in the overhead mixture is separated from the non-condensable gas or gases by preferentially passing the vapor through a semipermeable membrane.  The water or other condensable vapor is then compressed and either reinjected at the bottom of the stripping column or con-densed in the column reboiler, thus permitting its reuse in the stripping process.  If the compressed vapor is reinjected into the stripping column, it serves as the stripping medium itself.  If the compressed vapor is con-densed in the column reboiler, its latent heat of vapori-zation is thereby recovered and used to generate the required stripping vapor by boiling the solution being stripped.

Deflection means (20) cause a bow wave in descending slurry which fans out the concentrate aiding precise setting of downstream splitter blade (18) as well a diverting the overlying depletion band towards outer wall (13).  In preferred embodiment water which has become separated from the slurry due to centrifugal force is re-homogenized with slurry by restricted passage between deflector means (22,26).

Abstract: Abstract An input fingerprint image consists of ones and zeros pixels representing light and dark pixels which in turn correspond to ridge and valley formations. This image is compared with a reference file fingerprint to  verify the identity of the input fingerprint.  The reference file has two relatively small segments which are subfields  of the entire field of pixels that constituted the  original fingerprint image for the individual involved. Two substantially larger domain subfields are extracted from the input fingerprint image.  The center of each segment corresponds to the center of a respective one of the domains.  Each segment is scanned over its corresponding domain to determine the position of maximum ones correlation and maximum zeros correlation between each segment and its corresponding domain.  These four positions together with the correlation values associated with each of these four positions are subjected to various criteria to provide positive or negative verification of the input image relative to the reference file.  These criteria include (a) positional closenes to one another, (b) exclusion of the positions from a predetermined border of the domain, (c) closeness of the correlation values of certain of the positions, and (d) magnitude of the sum of the ones correlations and zeros correlation for certain of the positions.

Abstract: TENSION INDICATING WASHER FOR SMOOTH AND IRREGULAR SURFACES      ABSTRACT        Disclosed is a one-piece indicator washer, adapted for  use with  a  nut  and bolt assembly to indicate in a predetermined manner predetermined  amounts of tension in the  bolt,  comprising  a  dished  annular  member of  a predetermined thickness having a concave first surface, a convex  second surface,  and  a  centrally  disposed  bolt receiving aperture, with the concave first surface defining a  bearing  surface  proximate  the  outer periphery of  the annular  member,  the  convex  second  surface  defining  a bearing  surface proximate  the  aperture,  and  the bearing surface proximate the outer periphery of the concave first surface including at least one relieved area.  Means for indicating are integrally formed with and extend axially from  proximate  the outer peripheral  edge  of  the  dished annular member, the means for indicating including radially disposed    axially   extending    reference   means    and circumferentially disposed arm means.   The arm means for indicating  include  circumferentially disposed arm means, the arm means supported axially from the washer by one end of the arm means proximate to the outer periphery of the washer, with the free end of the arm means spaced from the reference means in a predetermined manner.  Thus, when the washer is used with a support surface having irregularities and a force is applied to the washer, increased tension in the  bolt  tends  to deflect  the washer  towards  a planar condition,  thereby  causing the  arm means  to move  in  a predetermined manner to a predetermined position relative to the reference means.   The relieved area precludes the surface  irregularities  from  affecting  the  predetermined manner in  which  the  arm means  and  the  reference means indicate a predetermined measure of tension in the bolt.
