Abstract: ABSTRACT OF THE DISCLOSURE             According to the invention a method for forming shaped articles from pre-expanded thermoplastic beads, in two cycles, comprises  a first cycle which includes the stages of introducing said beads into a mold cavity of a first mold to fill said mold cavity, wherein said first mold comprises two members, a male member and a female member, and wherein said first mold is maintained at a substantially constant elevated temperature throughout said two cycles, injecting steam into said first mold to cause the beads to expand, partially melt, agglomerate and form a shaped cellular preform, disengaging said two members of the first mold whereby said preform is retained by one mold member of said first mold, and a second cycle which includes the stages of transferring said shaped cellular preform at substant-ially ambient pressure, from the first mold to a second mold, by conveying said preform on said first mold member which retains said preform to said second mold, whereby the shaped preform is free to expand under the conditions of the stage of transferring, wherein said second mold is at a second substantially constant temperature throughout said two cycles, wherein said second substantially constant temperature is lower than said substant-ially constant elevated temperature and wherein the cavity of said second mold has the shape of the ultimate shaped article, cooling and compressing said shaped cellular preform in said second mold, and removing the finished article from said second mold.  The method and apparatus are expecially adapted for high production rate of any thermoplastic material articles such as shock absorbing pads for packaging.

Abstract: ABSTRACT OF THE DISCLOSURE      Apparatus for open-end spinning textile yarns comprises fibre feed means, spinning means to receive fibres from the fibre feed means and to spin them into a tail end of yarn for continuous withdrawal of yarn from the spinning means, and yarn withdrawal means to withdraw the yarn along a yarn with-drawal axis to a yarn delivery aperture of the spinning means and to form the yarn into a package.  The yarn withdrawal means comprises a package forming assembly and a yarn engaging means.  The package forming assembly is operative to form a package of the yarn and has yarn distributing guide means to distribute the yarn on the package.  The yarn engaging means is operative to engage the yarn in its passage between the yarn delivery aperture and the yarn distributing guide means.          The yarn engaging means and the yarn distributing guide means are mounted on opposite sides of a plane containing the yarn withdrawal axis in such disposition that the distance travelled by the yarn from the yarn engaging means to the yarn dis-tributing guide means is greater than the distance from the yarn delivery aperture to the yarn distributing guide means.

Abstract: ABSTRACT OF THE DISCLOSURE         A one-piece piston rod wiping seal member for cleaning reciprocating piston rods or plungers as the rod moves into the cylinder chamber for cleaning dust and other foreign matter from the surface of the rod to present the foreign matter from en-tering the working chamber and contaminating the interior there-of.  The wiping seal member is of one-piece construction and -includes an endless body portion of elastomeric material with a pair of lips projecting axially and radially with respect to an end wall of the body member.  One of the lips is a rod en-gaging lip and projects radially inwardly to engage the sur-face of a piston rod.  The other lip is a cylinder end cap en-gaging the lip for engaging the end cap of the cylinder.  The body portion can be snap fitted into a groove in the end cap of the cylinder.  When installed, clearances are provided be-tween the surfaces of the mounting groove of the end cap and the surface of the body portion of the seal member to prevent over stressing of the wiping lips upon lateral movement of the piston rod.

Abstract: SOUND PROCESSING METHOD AND APPARATUS                    ABSTRACT OF THE DISCLOSURE     A method and apparatus are described for electronically processing sound.  An electrical signal derived from audio information is split up into two separate signal paths.  The signal travelling along one path is passed through an exciter circuit and an attenuator and is then combined with the signal travelling along the other path.  In one embodiment of the invention the signals travelling along the two paths are combined electronically and in another embodiment of the invention the two signals are combined acoustically.  The exciter circuit is made up basically of a high pass filter and a harmonic creator. The harmonic creator is designed to create low order, odd and even harmonics of frequencies whose amplitudes are above a preselected threshold level.  Two versions of the exciter circuit are disclosed, one containing vacuum tubes and the other solid state.  The quality and various other characteristics of sound that is processed according to this invention are believed to be greatly enhanced.

Abstract: ABSTRACT          The present invention relates to a contact insertion tool.  The insertion of contacts directly into the bores in a connector body sometimes causes damage to the internal diameter restrictions with insertion of the contacts being slow and difficult at best.  The present invention overcomes these deficiencies by providing an improved tool, together with a unitary control mechanism for such a tool.  The tool has bore enlarging means including a sleeve and a rod co-axially aligned within the sleeve for insertion into the bore of the connector for enlargement thereof.  The unltary control mechanism, operatively associated therewith enables relative movement between the sleeve and the rod, and includes spring release means which in a first position resists rearward movement of the sleeve and the rod, in a second position permits rearward movement of the rod but resists rearward movement of the sleeve, and again in the first position permits rearward movement of the sleeve for relative sequential movement between the sleeve and the rod. The tool can also include an opening therein having first and second pistons controlled by the unitary control mechanism with the sleeve being secured to the first piston and the rod being secured to the second piston.
