Abstract: ABSTRACT OF THE DISCLOSURE            The invention is for an improved hinge for pivotably connecting an eyeglass temple piece to an eyeglass frame, which permits a stable positioning of the temple piece in a  folded or closed position in order to conveniently store the eyeglasses and a stable positioning of the temple piece into a normal open posi-tion for wearer use of the frame and which permits still further elastic movement of the temple piece beyond the normal open posi-tion without damage to the frames or hinge.  The improved hinge includes a rod-shaped slide which is slideably mounted in a seat provided in the end portion of the temple piece and which pro-trudes from the seat.  A hole is formed in the slide which extends coaxially in the slide over a predetermined depth from its pro-truding end.  A slot is formed in the slide which extends longi-tudinally in the slide over a predetermined length from its pro-truding end.  The predetermined length of the slot is less than the depth of the hole in the slide and the slot debouches in that hole.  A block is fastened transversely at the mouth of the seat, extends through the slot and constitutes an axial guide for the slide.  A spring is mounted in the hole in the slide having an end in pressing contact with the block and another end in press-ing contact with the bottom wall defining the hole.

Abstract: COMBINED LINEAR MOTOR AND SIDE MOUNTED OUTBOARD CARRIAGE     ABSTRACT OF THE DISCLOSURE           A linear motor and side mounted outboard carriage combination.  There is an elongate magnetic core having a longitudinal motion axis.  An armature is asso-ciated with the core and can move along the axis.          Carriage ways are secured on opposite sides of the core.          A carriage assembly is mounted on the ways and connected to the armature for movement with the carriage along the axis.  Portions of the carriage assembly are mounted on the opposite sides of the core and are so arranged that the center of gravity of the carriage assembly and all elements connected to it is approximately aligned with the center of force of the core.  The invention is useful in all circumstances where prior linear motors and carriage combinations are useful but is of particular value where high precision of movement is required, for example in a computer disc drive.  The combination of the invention has its center of gravity in line with the center of force provided by the motor and this reduces structural resonance.  Further the result of a crash against a stop is not as serious as in prior art com-binations of carriage and motor.

Abstract: ABSTRACT OF THE DISCLOSURE           A vibration-isolating apparatus for protecting equipment from excessive vibrations.  The apparatus discloses an equipment-carrying frame attached by shock-absorbing members to a guide member.  The guide member is loosely fastened in operational relationship with a drillpipe or casing to permit movement of the apparatus.  The apparatus is lowered along the drillpipe or casing by a cable or other locomotive means controlled from the surface.  Vibration of the drillpipe created by ocean currents or waveloading forces causes the drillpipe to impact and vibrate the guide member of the apparatus.  The shock-absorbing members protect equipment attached to the frame by attenuating the excessive vibrations induced by the drillpipe on the apparatus.  Shock-absorbing members of varying stiffness can be substituted to attenuate the differing vibrational forces exerted by each partic-ular drillpipe.  The stiffness of the shock-absorbing members is preferably selected to provide the optimal combination of rigidity and damping properties necessary to protect the equipment.

Abstract: APPARATUS FOR FORMING STRUCTURAL SHEETS      FROM FIBROUS BIOLOGICAL WASTE       Bolek (nmi) Dvorak Inventor Abstract of the Disclosure The apparatus  accepts  dry stripped crude fiber such as straw  or  sugar  cane wastes, coconut husks, or elephant grass, compacts them into a relatively dense sheet, and bonds  a strong surfacing material such as a heavy paper to the faces and edges.          The sheet, continuously flowing from the apparatus,  is cut into standard lengths and the cut ends are capped with the same  sur-facing  material.   A  precompactor  near the end of an  entrance chute  into  the  apparatus uniformly predensifies the  incoming fiber  prior  to its compaction by means of a ram.  The  ram  is carried  an roller bearings especially adapted to withstand  the weight  and other forces associated with the continuous movement of the ram.  The compacted material is continuously propelled by the  ram  and enters a press, where heat and pressure produce  a dimensionally stable sheet bonded together partially  by natural resins  released  from the fibers by the heat, and partially  by mechanical interlinking between fibers.  In the following opera-tion, the sheet is covered with the surfacing material, which is successively  folded  over and bonded to the edges of the sheet.     The   surfacing  material,  provided  in  discrete   rolls,   is continuously  available from a feeder station which  facilitates the  substitution  of a fresh roll as the material is consumed.          In  the  following  sawing  and end sealing  operations,  fully surfaced sheets of standard lengths are produced.

Abstract: ABSTRACT           The quadrupole shear wave logging device of this invention includes a logging sonde, means for generating a quadrupole shear wave in the earth formation surrounding a borehole containing fluid, and means for detecting in the fluid the refraction of the quadrupole shear wave.  In the preferred embodiment, the generating means comprises four similar sectors of a hollow piezoelectric cylinder.  The four cylinders are polarized radially.  The four sectors are so connected to the sonde that they are in the form of a split cylinder coaxial with the sonde axis.  Electrical pulses of similar waveforms are applied across the inner and outer cylindri-cal surfaces of each sector to vibrate the four sectors.  The electrical pulses are of such polarities that, during their initial motions of vibra-tion, two oppositely situated sectors are caused to move outward and the remaining two oppositely situated sectors to move inward substantially simultaneously.  Thus, the oppositely situated sectors will vibrate in phase whereas adjacent sectors will vibrate substantially opposite in phase. The vibrations of the four sectors generate four pressure waves: two positive pressure waves and two negative pressure waves.  The four pressure waves generated will interfere and produce a quadrupole shear wave in the formation.  The pressure wave in the fluid caused by refraction of such quadrupole shear wave is detected by the detecting means comprising two detectors in the fluid spaced apart longitudinally from each other and from the generating means.  Shear wave velocity of the formation may be determined from the time interval between the detections of the refraction of the quadrupole shear wave by the two detectors.
