Abstract: ABSTRACT OF THE DISCLOSURE      A yarn tension control apparatus for tensioning a running length of yarn such as textile yarns or the like, wherein a plurality of tensioning devices form a controlled channel and are controlled by an electronic control circuit having a manually adjustable tension setting potentiometer for adjusting a circuit to provide output voltages to the tension devices of the channel adding selecting tension values to the yarn.  The tensioning devices each comprise an electromagnet coil and core structure alongside which a pair of wear surface members in the form of plates or discs are supported in parallel vertical planes with the yarn running between and engaging the confronting surfaces -of the wear surface members and the wear surface member located beyond the yarn plane from the coil and core structure being of magnetic material to be drawn toward the companion wear member by magnetic attractive forces to vary the tensioning of the yarn leaving the yarn tension devices.  In the disc wear member embodiment, one of the discs is driven by a motor to effect a wiping action on the yarn.  Degaussing circuit means are also disclosed for applying intermittent negative going pulses descending to a negative voltage level to the electromagnet coils during downward adjustment of the tension setting potentio-meter to minimize residual magnetic effects.

Abstract: ELECTRICAL SOCKET CONNECTOR CONSTRUCTION            Abstract of the Disclosure An electrical socket connector construction for receiving the terminals of an electrical integrated circuit pack in which the body of the connector is formed in two steps.  A housing is initially molded in rectangular, box-like form, its base initially being in two sections separated by a small gap.  In a second step, the side walls are forced together to close the base gap and are locked together by a latching mechanism at each end.  The top wall is buckled upward in the gap closure along hinge lines to form two peaked members each having a longitudinal slot on the inside of the housing.  Rows of aperatures formed in the top wall and base admit the circuit pack terminals in the top and fit two-bladed contact receptacles in the base. One blade of each row is extended to engage a slot of the top members which, in their peaked state, hold the blades open.  As the terminals of an integrated circuit pack are inserted therebetween, the body of the circuit pack forces the peak juncture of the top wall members downward beyond the horizontal in a "snap" action against the resilient spring action of the side walls.  As a result, the extended blade of each contact receptacle is forced against a clasped terminal for positive electrical contact and locked-in securing of the integrated circuit pack.

Abstract: The invention relates to a process and to equipment for the manufacture of articles from a thermoplastic of polyester or polyamide type, preferably of polyethylene terephthalate, the element consisting of an edgepart which surrounds a body in an arrangement in which the latter is sunk relative to the edge part. The element is formed from a blank of mainly amorphous material or from a material having a crystallinity of less than 10%. The blank consists, for example, of a flat plate, a blank shell or the like. The body or parts thereof are shaped by stretching the blank until that material flows which is located within the material sections of the blank, which form the edge part in the element, the material stretched up to flowing in the body assuming a crystallinity of between 10%and 25%, whilst the crystallinity in the material in the edge part and in the unstretched parts retains its original value of less than 10%. At least the body of the element is expanded against warm mould walls until the final shape of the particular article is obtained. Optionally, the expansion is preceded by a number of drawing steps with an axial elongation of the body coupled with a simultaneous reduction in its dimensions at right angles thereto.

Abstract: ABSTRACT OF THE DISCLOSURE         A prosthesis for a joint of the human body, such as the metacarpophalangeal, knee, or other joint.  The prosthesis includes at least a pair of elongated stem members adapted to be inserted into and bonded to two bones which meet to form the joint. The adjacent surfaces of the two stem members form an interface with each other to present the prosthetic joint interface.  The two members are interconnected by a pivot mechanism comprised of a rotatable element in a slot in a first of the stem members, and an L-shaped in pivotally coupled to the element and to the second stem member so that the second stem member can pivot rela-tive to the first stem member about three different axes.          The mechanism is made so that the pivotal movement of the second stem member relative to the first stem member about any one of the axes can be accomplished without imparting significant torsional or bending loads to the first stem member.  This assures that the first and second stem members remain implanted in the respective bones at all times.

Abstract: IMPROVED PROCESS FOR RECOVERY OF RESIDUAL BITUMEN   FROM TAILINGS FROM OIL SAND EXTRACTION PLANTS                   Abstract of the Disclosure Bitumen in primary separation vessel underflow and bitumen plus diluent naphtha in aqueous effluent from centrifugation plants that together represent losses of 8 to 12% of oil in oil sand feed to a hot water extration plant may be substantially recovered by settling and flotation scavenging after tailings fractions have been subjected to a tumbling, mixing or shearing process.  The process of the present invention includes the possibility of dilution of the sand while raising the bitumen content of the primary separation vessel under-flow by admixture with centrifugation plant tailings, unscavenged primary separation vessel middlings or bituminous sludge from a retention pond, subjecting the resulting mixture to a tumbling, mixing or shearing action with incorporation of air or alternative gas bubbles followed by settling of the sand with passive or gas induced flotation scavenging of bitumen which can be promoted by use of carbon dioxide.  By providing a back-up recovery system capable of efficient scavenging of residual hydrocarbon the hot water process can be operated at increased throughput, lower temperatures, reduced sensitiv-ity to clay-water ratios and increased extraction efficiencies.

Abstract: SPEECH DETECTOR     Abstract of the Disclosure Samples of a transmit path voice channel signal are averaged and compared with an adaptive speech threshold to determine the presence of speech.  When the average falls below a fixed threshold, a timing circuit is triggered to time a delay period followed by a noise averaging period.  The timing of these periods is aborted if either the transmit path average, or a similarly produced receive path average, exceeds the fixed threshold during either period.  During the averaging period the voice channel signal is averaged, and at the end of this period the average noise level is used to determine the adaptive speech threshold, a predetermined level above the average noise level, the new adaptive speech threshold being stored.  The stored adaptive speech threshold is not changed unless the timing of the delay and averaging periods is completed, ensuring that only the noise is averaged to determine the adaptive speech threshold.
