Abstract: This invention is directed to coating press fabrics to achieve a controlled void volume. More particularly, this invention is directed to a method of modifying a press fabric for a papermaking machine which comprises the steps of:(a) applying a thin layer of a polymeric foam to the surface of a press fabric;(b) drying said foam to form a coated press fabric; and(c) curing said coated press fabric.

Abstract: A communication network, such as an audiovisual system, on an automobile has a master unit and a plurality of slave units which are connected to a common communication bus. Each of the master and slave units is capable of successively issuing a plurality of command data through asynchronous transmission to another unit and returning acknowledgement data in response to the command data transmitted from another unit. The units add received command data to acknowledgement data when the acknowledgement data is to be returned. The command data includes first command data requiring acknowledgement data and second command data requiring no acknowledgement data. Each unit handles the first and second command data differently when the acknowledgement data is to be returned. When communication data is to be transmitted between the units, major classification data and subclassification data, depending on the contents of the communication data, are added to a leading portion of the communication data.

Abstract: Apparatus for processing digitized images, the apparatus being of the type comprising a matrix memory (104) of pixels (106) organized as N lines (108) by P columns (110), together with processing means (130) for determining which pixels (106) are in the excited state by reading the memory (104). The processing means (130) operate by determining and storing the address of an excited pixel (106) that occupies an extreme position in a line or a column position, by switching said pixel (106) to a non-excited state, and by reiterating these operations until none of the pixels (106) is excited.

Abstract: The invention comprises apparatus for determining the orientation of the crystallographic axes of a single crystal. The crystal is rotated on a turntable while an X-ray beam containing characteristic radiation is directed onto it. A stationary position-sensitive detector, preferably positioned at right angles to the beam detects Bragg reflections from the crystal, and computing means responsive to the signals from the detector, and signals representing the angular position of the turntable determines the crystal orientation.
