Abstract: ABSTRACT OF THE DISCLOSURE      A method and machine are provided for controlling the orientation of one or more sewing instrumentalities with respect to a workpiece while also controlling the path of movement of the workpiece. The one or more sewing instrumentalities are preferably rotated about an axis perpendicular to the plane in which the workpiece is moved.          The invention furthermore provides for separate and independent control of each sewing instrumentality so as to thereby render one or both needles inoperative at various us times during continuous operation of the machine. The invention still further provides for separate manipulation of the thread associated with each respective sewing instrumentality so as to allow for a pullback of this thread. In principle the invention is also applicable to other than sewing machines wherein one or more operative tools may, for example, perform such functions as marking, folding, pinking, or perforating.

Abstract: ABSTRACT OF THE DISCLOSURE            A handrail and crash rail comprises a rigid retainer and a cover of a resilient, impact-resistant plastic mounted on the retainer by means of upper and lower flanges on the cover which engage and are held on corresponding flanges on the retainer.  Clearances are left between the impact wall of the cover and the front surfaces of the retainer flanges so that the cover can deflect inwardly toward the retainer upon impact.  At least one longitudinally extending, resiliently compressible cushion mounted on the retainer between the retainer flanges engages the impact wall of the cover to control the extent of deflection of the cover upon impact, absorb some of the energy of the impact, and restore the cover to its initial position after impact.  Additional cushions can be included.  Special internal and external corner assemblies and an end assembly are used with rail sections to form a complete rail system.

Abstract: RANDOM STUFFER RIBBON CARTRIDGE WITH IMPROVED RIBBON EXIT CONTROL                      Abstract of the Invention An improved ribbon exit control, in combination with a random stuffing ribbon cartridge is disclosed which prevents the accidental jamming of the ribbon at the exit port of the storage chamber.  The exit port is formed by two mating members whose surfaces are configured, when mated, to form a slot which is of a curvelinear shape such as the form of an arc of a circle or an angled relatively flat lazy V shape.  An alternate form is a slot punched in a one piece member to define the slot.  The deformation of the slot from that of a straight line causes the ribbon to buckle as it is pulled from the storage chamber and assume a cross-section other than that of a straight line.  This acts to separate the ribbon strand being removed from the chamber, from any other adjacent folds of the ribbon.  Since the ribbon strand and the adjacent folds are separated by the deforming of the ribbon it is more difficult for an adjacent fold to be pulled into the exit gate thereby causing a jam.  The width of the slot is controlled by width control fingers extending across the end of the slot to an abutment surface. The uniform slot width improves reliability and the width control fingers further act as top and bottom constraints preventing the ribbon from pulling out of the slot and circumventing the exit port.  The fingers also regulate not only the slot width but also the uniformity of the slot width top to bottom.

Abstract: FAST RELEASE CONNECTOR            ABSTRACT OF THE DISCLOSURE          An electrically conductive connector adapted to be releasably coupled with a stud to form an electrical connection.          The connector includes an electrical terminal with an electrically conductive terminal aperture.  The aperture has a larger diameter than the stud so as to facilitate introduction of the stud therein.          A set screw is threadedly mounted on the electrical terminal in position to be actuated from the exterior of the electrical termi-nal and to be reciprocally passed across the aperture to engage the stud inserted therein and form a fixed electrical connection between the stud and connector.  Release of the set screw permits the stud to be removed from the connector.  The aperture has a configuration to permit it to cooperate with the set screw and stud to stabilize the interconnection therebetween.  This is particularly true when the connection is subjected to forces acting other than along the axis of the set screw that otherwise could cause loosening of the interconnection between stud and connector.  At least one terminal port is provided to facilitate electrical connection to selected conductors.

Abstract: ABSTRACT:       The invention relates to a method of frame synchronisation of a digital time-division multiplex communication system and to an arrangement for performing the method.  During the search for a syn-chronisation pattern of M bits in frames, each consisting of N time slots, a shift register of N x M bits is usually used.  The method according to the invention has for its object to reduce the number of bit storage capacity required  The method operates as follows.  At the start of the synchronisation process the first bit of the syn-chronisation pattern is expected.  If this expectation comes true, the second bit of the synchronisation pattern is expected in that time slot in the immediately subsequent frame etc.  If the expectation does not come true then the (partially) received pattern is no synchronis-ation pattern and the procedure is performed again in that time slot. The method is based on the recognition that is is not necessary to store the partially received synchronisation pattern in a store, but that it is sufficient to store the numerical order of the bit of the synchronisation pattern expected in the time slot of the next frame. Consequently, a storage capacity of N x 2 log M is sufficient.  The method can be performed with a microprocessor or with "wired" logic circuits

Abstract: AUTO-ZERO AMPLIFIER CIRCUIT WITH WIDE DYNAMIC RANGE Abstract of the Disclosure An operational amplifier is continuously switched back-and-forth between an auto-zero mode of operation and an accurate amplification mode of operation. During the auto-zero mode of operation, the junction between an offset voltage compensation (e.g., auto-zero) capacitor and the noninverting input of the operational amplifier is referenced to the input signal voltage via a bootstrap amplifier rather than being tied to ground. Further, during the auto-zero mode of operation, the other end of the auto-zero capacitor is referenced to the output of the operational amplifier, which is also connected to the inverting input of theoperational amplifier. As a result, the auto-zero capacitor is charged to a voltage level equal to the input offset voltage of the operational amplifier, but in polarity opposition thereto. During the accurate amplification mode of operation, the input signal is applied to the noninverting input of the operational amplifier via the auto-zero capacitor. As a result, the charge on the auto-zero capacitor cancels the input offset voltage of the amplifier whereby the output of the operational amplifier is accurately related to the voltage of the input signal by the gain of the operational amplifier. Because the auto-zero capacitor is referenced to the input signal voltage during the auto-zero mode of operation, rather than being tied to ground, voltage swings at the output of the operational amplifier and across the various switch elements are kept low. As a result, the auto-zero amplifier circuit is operable over a wide dynamic range.
