Abstract: Abstract of the Disclosure An electrical outlet box formed of nonmetallic material  which  has  a  pair  of  integral  bosses  that angularly align, engage and retain wiring device mounting screws therein.  The bosses each have a through bore for receiving   the   screws   comprising   in   sequence   a frustoconical surface, a first cylindrical surface having a diameter slightly larger than the crest diameter of the mounting screw threads, and a second cylindrical surface having  a  diameter  slightly  smaller  than  the  crest diameter of the screw threads and slightly larger than the   root   diameter  of   the   screw   threads.    The frustoconical and two cylindrical surfaces are coaxial, with  the  frustoconical  and  first  cylindrical  surfaces angularly aligning the screw substantially coaxially of the bore and engaging the screw to resist inadvertent removal  of  the  screw  from  the  bore,  and  the  second cylindrical  surface  threadedly  retaining  the  screw therein upon rotation of the screw along that surface.          An annular shoulder is defined at the interface of the first and second cylindrical surfaces.

Abstract: ABSTRACT OF THE INVENTION The invention provides a modular robotic wrist system for use with an industrial manipulator or the like. The individual modular units comprise a mounting bracket, an A axis module which is attachable to the mounting bracket and provides rotational movement about a first axis, a B axis module which is mountable either directly to the mounting bracket or to the A axis module to provide either rotational movement about a second axis or addition-al rotational movement about the second axis in conjunction with the rotational movement provided by the A axis module about a first axis and tool-mounting flanges which can be used in conjunction with the B axis module to provide rotational movement of an end effector either on the second axis or radially spaced about the second axis.  Each of the modular units has a rotating member which is driven by a high-speed, low-torque DC motor coupled to a harmonic drive unit.  The individual modules can be provided with position feedback mechanisms which provide both speed and locational information.

Abstract: ABSTRACT OF THE DISCLOSURE      To resist tampering with the contents of container for pharmaceuticals and other products, a plastic cap which is an improvement upon U. S. Pats. 3,338,446 and 4,166,552 and U. E. Serial No. 517,666.  The neck of the container is sealed with a commercially available foil seals the cap is dimensioned so that the foil seal is inserted inside the cap prior to its being applied to the container.  The dimensions of the cap accommodate the foil seal yet the snap-on and tamper-proof features of the cap are maintained.  A thin flange projecting from the periphery of the cap is used to remove the cap in its reclosure mode; however, this flange is shaped so that if one attempts to use the flange to pry off the cap when in its original sealing mode, sufficient force cannot be applied.  The present cap skirt has upper and lower internal beads separated by a horizontal scoreline.  The beads may be continuous or, preferably, interrupted.  They may be closer together and closer to the top disc than in prior caps of this type.  The upper bead may be much thinner than in prior structures. The skirt below the beads is elongated and frictionally engages the outside of the container neck to inhibit tampering.  Various cap bead shapes are disclosed.

Abstract: Abstract A Waterproof Floor Formation In a waterproof floor formation, in which an asphalt-coated sheet with a covering of ceramic tiles thereupon is laid on a supporting base (or floor pavement), the asphalt covering on the asphalt-coated sheet facing the supporting base is less thick than the asphalt covering located on the other side, and the ceramic tiles are provided with a relief structure on the side facing away from the visible side.          Thus, a waterproof floor formation is proposed which rules out the danger of the waterproof sheets being damaged when the tile material is laid and, furthermore, by which an even, smooth visible side of the floor covering can be obtained in every case.

Abstract: ABSTRACT     A pressure operated test valve for use in a well test string  in a well bore is shown.   The test string has a packer arranged for  sealing the well bore to isolate the annulus between the well bore and the test string above the packer from that portion of the well bore below the packer. The  test  valve  includes  a  rotating  ball  valve  which  is movable between open and closed positions relative to the interior  of  the  test string.   A ball piston shifts the rotating ball between the open and closed positions.  A coil spring normally urges the ball piston to its valve closing position.   A power fluid reservoir contains a power fluid and an axially shiftable power valve is located within a power  chamber  which  communicates  with  the  power  fluid reservoir.   An axially slidable control valve  is located within  a  control  chamber  and  has  a  pressure  responsive annular  area  which  is  exposed  to  the  power  fluid  for shifting  the  control valve.   The  control valve also has internal passages for supplying pressurized power fluid to the power valve to shift the power valve between a first position  which  isolates  the  ball  piston  and  a  second position which  exposes  the  ball piston  to annulus  fluid pressure for shifting the ball to the open position.   The well  hydrostatic  pressure  is  trapped  within  a control section  of  the  device  prior  to  setting  the  packer  and provides the reference pressure for subsequent shifting of the valve.

Abstract: A B S T R A C T      A VEHICLE LOAD MONITORING SYSTEM    A  vehicle  load  minotoring  system for a tipping vehicle is disclosed which both provides the driver with useful information during loading to enable him to ensure compliance with legal limits on certain load parameters, and checks on various vehicle variables before or during tipping to inhibit the occurrence of situations in which the vehicle may become unstable, e.g. when parked on an incline.  On loading, measured load weight components are corrected  in accordance  with  a  detected  longitudinal (front-to-back) vehicle inclination and calculated load parameters are compared with thresholds which have been predetermined in accordance with the legal restrictions. In unloading, the position of the centre of gravity of the load is calculated and longitudinal and lateral load inclinations are detected, and the locus of the centre of gravity during tipping is predicted.  If it is determined that  the  predicted  locus  will  cause  a  condition  of vehicle  instability,  tipping  or  further  tipping  is inhibited and an alarm given. Additionally or alternatively, prediction  of  unstable  conditions  can  be  carried out  before  tipping  commences,  and/or  a  dangerous situation due to shifting load can be detected during tipping.
