Abstract: Processes and systems are provided for cooking wood chips containing knots in a digester to produce a chemical pulp. Specifically, a low pressure slurry of comminuted cellulosic fibrous material is formed in a vessel operating at essentially atmospheric pressure by mixing therein a liquid and the comminuted cellulosic fibrous material. The low pressure slurry is thereafter supplied to a low pressure inlet of a high pressure transfer device while liquid is removed from the slurry through a low pressure outlet thereof. A high pressure liquid is supplied to the transfer device (e.g., via a slurry pump) so as to form a high pressure slurry of the comminuted cellulosic material which is then discharged from a high pressure outlet of the transfer device. Knots are removed via a knot separator from a slurry of uncooked knot-containing cellulosic material at essentially atmospheric pressure. The removed knots are thereafter transferred to the vessel so that the knots become part of the low pressure slurry supplied to the low pressure inlet of the transfer device.

Abstract: In a method of forming patterns for bead-inlaid plates original pictures such as photographs are used which are converted to digital, bitmapped representations. From such a representation a pattern is then produced by a user selecting an area of the represented picture, by dividing the picture using a grid of intersecting lines forming squares and then a color matching in each square. In an interactive process, the colors in the squares are modified.

Abstract: The invention relates to a method and an apparatus for determining gas concentrations. The method utilises the interaction of gas molecules with elastic surface waves on piezoelectric solids. These transducers result in integrable microelectronic components which can be produced with conventional planar technologies. The measurement result can be evaluated in "on-line" operation using simple electronic modules of low weight and small dimensions. The novel method and the novel apparatus are used, for example, in determining the concentration of anaesthetic gases and in anaesthetic respiration to check, monitor and control the anaesthetic procedure.

Abstract: O-acetylated glycals react with ceric ammonium nitrate in the presence of sodium azide to provide, in good yield, O-acetylated 2-azido-2-deoxy glycosyl nitrates. These nitrates can be used to prepare 2-amino-2-deoxy sugars, such as D-galactosamine and lactosamine. The O-acetylated 2-azido-2-deoxy glycosyl nitrates can alternately be converted to O-acetylated 2-azido-2-deoxy glycosyl halides which are useful in the preparation of O-acetylated 2-azido-2-deoxy glycosides, which in turn can be reduced to 2-amino-2-deoxy glycosides. Of particular interest are the syntheses of 2-amino-2-deoxy glycosides which correspond to the terminal units of the antigenic determinant for the human A blood group. Attachment of these glycosides to a solid support provides immunoabsorbents which efficiently and preferentially absorb anti-A antibodies from blood plasma.

Abstract: PURPOSE: To reliably move an object such as a work piece by arranging a plurality of suction cups on a carrier through a process of facing their action surfaces in the same direction, and by providing a function for reducing pressure of a suction space formed when the action surface of an opening of each suction cup is closed lower than pressure of the suction space formed when the action surface is released. CONSTITUTION: A plurality of suction cups 45 are arranged on a carrier 39 while their action surfaces 45 face in the same direction and are flush with each other. A sucker 47 having plasticity is attached on the lower side of each suction cup 45, and a plate-shaped sensor 9 similar to the shape of the sucker 47 is attached on the upper side with a clearance 10 on the peripheral edge. When the sucker 47 is brought into complete-contact with an object, the sucker is extended by the weight, the peripheral edge 3 is brought into contact with the sensor 9 to shut off the clearance 10, and a suction space 48 of the sucker 47 is evacuated by a vacuum device 54. When the sucker is brought into incomplete-contact with the object, the clearance 10 is opened as it is, air is sucked from the clearance 10 and the suction space 48 through sensor pipes 11, 12, and a check valve 13 is closed.

Abstract: A rock drilling appartatus wherein the rock drill is a cluster of independent rock drills arranged in a circular pattern about a central axis for rotation. The cluster drill is drawn into a hole to be drilled by a drill string in a previously drilled smaller diameter hole. The drill string provides pressure fluid to operate the cluster drill and rotation as well as the tractive force to draw the cluster drill into the hole to form a large diameter straight drilled hole. Pressure fluid and rock cuttings exit the larger diameter hole and discharge of rock particles is further aided by use of a trailing auger rotated by the cluster drill. A particular application of this device is in the production of horizontal bored holes of moderate diameter under, for example, roadways, foundations, and the like. The drill string acting as a centering device produces a straight hole in difficult rock formations.
