Filed: 1996-03-01
Abstract: A rubber moir+E,acu e+EE  floor covering is disclosed. The covering is produced by continuously feeding a screw-type short extruding machine having a length/diameter ratio of 6:1 with two or three varicolored strips of vulcanizable elastomeric material. The operating temperature is between 60 DEG  C. to 100 DEG  C. The elastomeric material leaves the extruder via a perforated disk having 200 to 600 cylindrical bore holes 3-5 mm in diameter. Each of the resulting strands is severed to produce segments that are 1 to 2 mm thick, the formed pieces are then cooled off on a section 4 meters to 6 meters long. Subsequently, the formed pieces are allowed to fall into the roll nip of a temperature controllable two-bowl calendar. The web of material leaving the calendar is fed to a continuous vulcanization installation and leaves it as finished floor covering. The material throughput rate in this continuous process may be varied from 700 kg/h up to 1300 kg/h.

Inventor: GUAY BERNARD
IPC: H04L7/033
Filed: 1996-09-04
Abstract: A CML/ECL clock phase shifter device provides a 360° phase control range and, upon being provided with two CML clock signals related by a known phase difference, the device produces any desired phase in response to a control signal. The device uses a CMOS current switch which generates current signals having the amplitude adjustable with the control signal, which is a digital word. Differential pairs provide amplitude modulated current signals for the input clock and the variant of the input clock. Two MOS transmission networks selectively invert each amplitude modulated signal and sum the signals from each side on a load network. The phase control resolution is optimal over four quadrants for quadrature input clock signals.

Filed: 1995-11-17
Abstract: An optical scheme for in situ identification of particulates in fluid such as engine oil (12), in which a portion of the fluid flow is tapped, fed via a conduit (14) to a pair of optically transparent opposed plates (23, 25), imaged through the plates, and the fluid returned to the main flow (12). Imaging is preferably done with a laser (20) and photodetector array (26), and the output fed to a computer for image processing. Separation between the plates ensures all the oil therebetween will be in the imaging system's near field. Preferably, the computer counts the number of particles in the oil, and classifies their shape, by scanning the image until it hits an object (fig. 6), using known chain code to trace the object's outline, determining the object's aspect ratio, and repeating for each object in the image.
