Abstract: IMPROVEMENTS IN OR RELATING TO AMPLIFIERS                       ABSTRACT     A feedforward amplifier is designed to exhibit particularly linear transfer characteristics in which distortion signals introduced by the amplifier itself are minimised.  Two points within the feedforward amplifier are monitored and the phase and amplitude characteristics of respective adaptive equalisers are modified to reduce any distortions at these points.  A reference signal is injected directly into a main amplifying element so that it appears at the output terminal as though it were an amplified induced distortion.  The characteristics of the amplifier are adaptively modified to eliminate the reference signal from the output signal.

Abstract: ABSTRACT OF THE DISCLOSURE     In an apparatus for  girding packages with endless syn-thetic-resin strips, an assembly for bonding the ends of a web segment to one another comprises a press in the form of a fixed surface and a spring-loaded press bar shiftably mounted in a rotat-ing truncated drum along a diameter thereof.  An outer tangential-ly extending surface of the bar has a rotation path interrupted by the fixed surface.  The drum also carries a blade forming one side of a wedge-shaped channel for guiding  a trailing web-segment end during a bonding phase of an operating cycle.  Upon the begin-ning of the bonding phase a leading web portion surrounds the package and traverses the drum channel.  The rotation of the drum causes the press bar to clamp the web to the fixed surface, whereupon the blade cuts the web and produces a web segment having a trailing end.  A heating mandrel pivoted into a wedge-shaped space between a leading web-segment end and the fixed surface on one side and the trailing web-segment end and the press bar on the other side slips over a surface of the trailing web-segment end, while being pushed towards a rest position by the rotation press bar.  The press bar squeezes the heated segment end to the other end in a sweeping motion.

Abstract: WHEEL TRUCK                  ABSTRACT OF THE DISCLOSURE         A small, compact, collapsible three-wheeled truck which can be used to support a flat or damaged tire of a vehicle while the latter is being driven to a repair location.  The truck has a foldable ramp which rests flat on the ground while the rear wheels are in slightly raised position, so as to prevent movement of the truck while the flat tire is being driven  onto it.  As the ramp pivots upwardly into retaining position behind the tire,the rear wheels are lowered into ground contacting position.  Simultaneously, an extension attached to the ramp causes a retaining member near the front of the truck to pivot upwardly out of the way of the tire into front retaining position.  The tire after mounting rests in a cradle and is prevented from moving forwardly or rearwardly with respect to the truck.

Abstract: "PRETENSIONER FOR STRETCHABLE FILM WEB    WITH DANCER ROLLER COMPENSATION"    ABSTRACT OF THE DISCLOSURE A tensioner assembly pre-stretches a film web prior to unitizing a pallet load.  The film web undergoes three stages of stretch-ing by the tensioner assembly which includes two driven rollers and a resiliently biased dancer roller.  The dancer roller engages the film and maintains it under continuous tension loading as the pallet load rotates.  An electrical control signal proportional to the angular position of the dancer roller is employed by a control circuit to vary the rotational speed of the pretensioner drive rollers.  The Film web is stretched in a first stage between a feedstock roll and the first drive roller.  A second stage of stretching occurs between the first driven roller and the second driven roller.  Finally, the film web undergoes a third stage of stretching between the second driven roller and the pallet load, with the web being maintained under tension at all times by the resiliently biased dancer roller.
