Abstract: SUTURE INSPECTION AND GAUGING METHOD AND SYSTEM                   ABSTRACT The process of detecting faults in filamentary suture materials, such as braided polyglycolic acid and other synthetic polymer suture materials, is automated to allow an operator to continuously select upper and lower limits of acceptable suture diameters as well as frayed material  with the assistance, if desired, of both an audible alarm and appropriate electronic pulses responsive to deviations from specified limits.  A projected silhou-ette (34), obtained by coherent illumination (22) of con-tinuously fed suture material (12), is measured as it falls upon a self-scanned array of photosensitive detector elements (32) from which an output is received sequentially from adjacent detectors and where each output level is proportional to illumination of the corresponding detector in the array.  A single output signal can be used to in-dicate the presence of a fault.  In addition, three individual outputs, one each for each type of suture fault, for example, oversize, undersize and frayed material, may be utilized.  The system may also include signals which provide continuous suture size information and the infor-mation may be updated rapidly, such as 1000 times per second, enabling high suture feed rates.

Abstract: ABSTRACT        SPRAY SUPPRESSION ON MOTOR VEHICLES   A method of suppressing spray thrown up by motor vehicles as they travel at speed along a wet roadway is disclosed wherein a strip of flexible porous material is secured to the vehicle or a part thereof in the path of the spray.   The strip is several times longer than it is wide and would normally only be a few millimetres wide but many centimetres long and is preferably formed from aligned bristles held together along one edge of the strip by a bead.  The bead may be extruded around the ends of the bristles and is preferably shaped so as to provide means by means of which the strip is attached to the vehicle. The bead may, however, be of other constructions.           The strip may comprise a valance strip designed substantially to close off the space between a vehicle mudguard and the periphery of the tyre surrounded by the mudguard but additionally or alternatively a strip may be provided at the rear of each wheel or wheel set extending from a rear generally horizontal edge of the mudguard into close proximity with the road surface behind the wheel somewhat in the form of a mud flap and addtionally or alternatively a further strip may be provided extending inwardly across the mudguard in close proximity with the tread of a tyre. The strip may be of composite construction but a bristle arrangement is preferred since adjacent bristles can flex relative to each other and hence do not become clogged and by their very nature will tend to allow the passage of air therethrough but prevent water droplets passing therethrough.

Abstract: ABSTRACT       Apparatus and method for reconfiguring a memory in a data processing system to increase the rate of information transfer between system memory and processor.  The system memory is comprised of a plurality of memory banks, each bank being one or more words in width and having a separate data output path.  In a first configuration a memory controller addresses the memory banks as a sequential memory to read from one address location at a time and the output data paths of the memory banks are configured into a single, one bank wide data path to the system processor.          If each bank is one word wide and N words deep and there are M memory banks, the memory appears as a sequential, one word wide by MxN words deep memory from which one word may be read at a time.  In a second configuration, the memory is reconfigured by the addition of an address translator means and a bus reconfigur-ation means. The address translator means provides addresses addressing M banks in parallel, so that M locations are read in each read operation.  The bus reconfiguration means reconfigures the bank output busses in parallel, that is, into M parallel busses, and provides a selection means, responsive to the addres-sing means, for providing the information appearing on a selected bank output bus as the memory output to the system processor.          The memory is thereby reconfigured to be a parallel, M words wide by N words deep memory wherein M words may be read from the memory at a time.  In both the sequential and parallel configurations, the data path to the system processor, that is, the combined single width path of the sequential configuration and the selec-tion means output of the parallel configuration, comprise a direct data path from the memory to the processor.  In a further embodiment, a cache path is provided, connected in parallel with the direct data path, that is, from the parallel bank outputs to selection means output, or storing information in advance of information presently being processed.

Abstract: ABSTRACT OF THE DISCLOSURE:          A cable following apparatus having a rotating annulus at the front portion of the main body where the opening of the body passing over the cable first comes in contact with  the  concentric  neutral wires.   The  annulus,  by rotating in the direction of the neutral wrapping wires, has  the  effect of wrapping down any wires that  are broken. Further, a helical groove is cut in the front surface of the rotating annulus. The opening to this rotating helical groove extends beyond a static cutter plate which  comprises  a major  portion  of  the  front surface of the main body.  The groove angles back along one side of the annulus at an angle which is close to but  less  than the perpendicular to the direction of travel of the main body.  As a result, the terminal end portion of the helical groove is rotating in a plane slightly behind the static cutting surface.  Wires that are broken and pulled away from the cable are picked up and carried through the groove to a position where they are held against the surface of the static cutter and cut off by the force of the side of the helical groove pressing the wire  against  the  static  cutter  surface face.
