Abstract: The present invention seeks to provide a system for high speed intermittent motion. The system consists of one or more intermittent motion generators. Each motion generator consists of a first and a second drive system with each drive system having its own control software and control input information received from a programmable logic controller (PLC). Each motion generator employs dual cams with fixed angular rotation. The dual cam combination consists of a first cam nested within a second cam. The dual cams permit independent and individual motion generation for each motion generator. The angular rotation of the second cam relative to the angular rotation of the first cam causes a linear displacement which generates intermittent linear motion for each individual motion generator.

Abstract: A safety brake assembly is disclosed comprising a housing movable on a vertical support, the housing attached to a carpet support arm, a pulley rotatably mounted on a shaft of the housing, a link having an inner end pivotally connected to the shaft and an outer end connected to a first end of a pivot bracket on the housing, a second end of the pivot bracket connected to a wedge-shaped member adjacent the pulley, and tensioning means connected intermediate the ends of the pivot bracket. In the event of cable failure, the upward pressure previously exerted on the pulley is released, causing a downward movement of the pulley and link, the movement transferred by means of the pivot bracket to cause upward movement of the wedge-shaped member which is forced up between the pulley and the vertical support, the resultant friction arresting further downward movement of the housing and carpet support arm.

The invention also seeks to provide a method for using the apparatus, comprising rotation of a log through 360 degrees to allow for cutting at any desired angle along the length of the log. The method allows for maximal recovery of high-quality lumber.

Abstract: A flat woven papermaker's forming fabric having a paper side layer and a machine side layer interconnected by pairs of machine side layer weft binder yarns. Each of the binder yarn pair members in sequence interlaces with a portion of the machine side layer warp yarns in segments of the weft yarn path so as to complete an unbroken weft path in the machine side layer weave pattern, and to provide an internal machine side layer float. Each of the binder yarn pair floats interweaves with a paper side layer warp yarn so as to bind the paper and machine side layers together. The location of the internal floats in each layer determines the available interweaving locations, not all of which need be used. A wider choice of possible paper and machine side layer weave design combinations is thus made available in forming fabrics, thereby allowing for a better match between the forming fabric and the paper maker's requirements.

Abstract: A spectacles caddy can be attached by its spring clip to a vehicle visor or other similar substantially flat, thin, and stiff object. The shell of the caddy is made in two shallow elongate half boxes attached together at one short end by a hinge, and at the other by a latch closure. The latch is released by an exterior push button. A deformable member is provided in each shallow half box to grip the arms of a pair of spectacles inserted into the caddy. The longer side of each shallow half box also includes recesses, so that the sides do not grip the spectacle arms. The hinge is also constructed to limit the angular opening of the caddy to at most 45°, and preferably to about 30°, so that when in use attached, for example to a vehicle visor, the spectacles do not fall out when the caddy is opened to retrieve them.

Abstract: A method and apparatus for interference cancellation in a high-speed modem that includes a first coupler for receiving a differential signal including a received data signal, a second coupler for deriving a common mode signal for the transmitted signal, and a phase-shift circuit coupled to the second coupler for deriving orthogonal signals from the common mode signal. First and second multipliers mix the orthogonal signals with the received signal. First, second, and third integrators integrate the mixed orthogonal signals and the common mode signal to produce orthogonal signal level measurements ITONE and QTONE and a common mode signal level measurement CMTONE, respectively. A controller derives orthogonal correction signals from measurements by dividing ITONE and QTONE respectively by CMTONE and multiplying by an appropriate constant. This output is then used to increment or decrement the signals to the respective digital to analog converters, DACI and DACQ.

Abstract: Systems and devices for mechanically rotating the polarisation of a signal emanating from or being received by an antenna system. The rotation of the polarisation is achieved by mechanically rotating the feed using a non-metallic drive cord or belt connected to a motor which is displaced outside or behind the radiating aperture. For a linear array of multiple antenna elements, each feed for each antenna element is rotated simultaneously and by an equal amount through the use of a drive system common to all the feeds. The drive system is coupled to each feed and to a drive motor. When the motor is activated, the drive system simultaneously rotates each feed by a given amount. By rotating the feed, the polarisation of the signal is correspondingly rotated and compensation for polarisation loss is provided.
