Abstract: A method for real time message transmission in a token ring network is provided. The method initializes each node in the network, including setting a maximum message transmission time H.sub.i for node i such that ##EQU1## where C.sub.i is the transmission time of a message in a message stream, P.sub.i is the period length of the message stream, and a is a non-negative constant between zero and one. The messages are then transmitted when a token arrives at a node for the duration of H.sub.i. Using this method with the timed token protocol, the synchronous messages are guaranteed to be transmitted before their deadlines if the utilization of synchronous messages is no more than ##EQU2## of available utilization.

Abstract: A paper making machine comprises a press followed by an adjoining dry end having a plurality of dryer groups I to VI. Each dryer group comprises only one row of dryer cylinders and one row of reversal suction rolls which alternate with the dryer cylinders, and a respective endless support belt passing around the cylinders and rolls of each group along a guided meander path. The press and each of the dryer groups has a respective variable web speed drive. A speed control device controls the drives such that a positive difference in speed is present between the first dryer group and the press and a negative difference in speed is present between the last two dryer groups. Separation places may be defined between at least some of the dryer groups. Some of the separation places are closed providing support for the web passing between groups, and others are open providing an unsupported open draw for the web.

Abstract: A cutting device for a winding machine for winding a web of material, particularly a paper web, the winding machine having two support rollers, one of the support rollers being partially wrapped by the web of material which is advanced upward from underneath the support rollers and introduced into a space between the support rollers, to be wound into a finished roll which rests on the winding bed formed by the two support rollers. A tiltable cutting device includes a blade, a blade carrier, a connecting link, and a support structure. The blade carrier and the support structure are pivotally connected to each other by the connecting link in such a manner that the blade carrier can be tilted into a position in which the blade faces the web of material while the opposite end of the blade carrier rests against the outer surface of the unwrapped support roller.

Abstract: Improved multi-wall containers and pipes for transporting fluids which have to be protected against leakage and mechanical forces, have an inner and outer wall separated by a continuous foam layer integrated into the containers. Improved strength and resistance to axial inertial pressure is provided by the method of manufacture using chopped glass fibers, continuous windings of glass fibers and suitable polyester resins and circumferential ribs spaced at stress points and integrally incorporated into the containment walls. Vessels produced according to the methods of the invention have a moment of inertia strength of about 4.67 in.sup.4 substantially eliminating torquing, buckling and rupture.

Abstract: An easily and preferably fully automatically manufacturable thermal switch having a minimum number of parts is disclosed. The thermal switch has two connecting parts fixed to a support part. One connecting part carries a fixed contact and the other connecting part is connected through a high resistance to a movable contact switchable by a bimetallic element. The support part is a ceramic part forming the high resistance from a PTC material and the connecting parts are almost completely frictionally engage support part.

Abstract: A process for determining coordinate values of touchdown sites of a needle for forming sewing patterns with an electronically controlled sewing machine, which is equipped with a feed dog performing only relatively small amounts of displacement and with a needle pivotable in one direction of displacement of the feed dog. The coordinate values for a straight seam section, the consecutive touchdown points of the needle, are determined when the maximum amount of feed of the feed dog in the X coordinate direction and/or the sum of the maximum amount of the lateral movement of the needle which is possible at a given needle position and the maximum amount of feed of the feed dog in the Y coordinate direction is exceeded. The seam section is subdivided by equidistant intermediate touchdown sites, the distances between which in the direction of movement of the needle are composed of a constant percentage of the lateral movement of the needle and of a constant feed percentage of the feed dog.

Abstract: Disposable diapers are manufactured in a high-speed process with an elastic waistband formed of a stretched length of foam having an elastic memory by longitudinally stretching the elastic waistband length by gripping without penetrating at least one of its ends and fixing the stretched elastic waistband to the diaper layer along the waistband area. The end of the waistband length is positively engaged in a groove on a roller surface with a continuous belt which moves across the grooved roller surface and pinches without penetrating the end of the elastic foam length.

Abstract: A postage meter and system is provided for recharging the postage meter using a credit card number via communication over a modem with a manufacturer host. The postage meter has a nonvolatile register indicating an amount of postage resident in the postage meter. An account number register stores at least one credit card number which can be used for remote recharging of the postage meter. A constant nonvolatile register indicates a postage meter number permanently assigned to the postage meter. A modem in the postage meter transmits the credit card number and the postage meter number to the manufacturer host when requesting an increase in the amount of the postage resident in the postage meter. When the manufacturer host receives the request from the postage meter, the manufacturer host verifies that the postage meter number is among a list of valid postage meter numbers.

Abstract: A process for producing a moulding from an expanded styrene polymer. This process comprises applying gas pressure to particles of the polymer, introducing the particles under pressure into a mould, and reducing the pressure to allow at least some of the particles to expand in the mould and bond together to form the moulding.

The method comprises the steps of placing or collecting the anatomical material into a first cavity of a first portion of a container.

Abstract: The axes of a first press roll (1) and of a second press roll (3) lie in a press plane (E). Each of the press rolls has a respective journal (2, 4). The first press roll is supported in a first bearing bracket (5). The second press roll rests in a second bearing bracket (6) which is coupled, by means of flexurally soft tie-bar groups (7a, 7b . . . , 8a, 8b . . . ), to the first bearing bracket (5). In the unloaded condition of the roll press, the second bearing bracket (6) rests on the first bearing bracket (5). In the loaded condition, however, a clearance (p) is established between the bearing brackets (5, 6), which permits the bearing brackets (5, 6) to be displaceable relative to each other in the axial direction of the press rolls.

Abstract: A nozzle, and FCC process using the nozzle for atomizing heavy feed to a riser reactor, are disclosed. A liquid feed stream is atomized by radial out-to-in impingement of atomizing vapor, discharged onto an impingement plug in an annular expansion region, then sprayed through an outlet. Baffles at the expansion region outlet, and an orifice outlet improve feed atomization and feed/FCC catalyst contact in a riser reactor. The nozzle may be used to distribute liquid over other reactor beds, or to add liquid to distillation columns.

Abstract: A method for part placement of a semiconductor chip for inspection where the semiconductor chip has a plurality of leads defining a seating plane and a body having a top. The method includes the steps of placing the body on a platform in an up position where the plurality of leads are suspended and probing the top of the body. Next measuring the position of the top of the body with reference to a predetermined coordinate system is done. Then the part is moved until the part is suspended on the plurality of leads on a reference plane. The top of the body is then probed for a second time, and the second position of the top of the body is measured with reference to the predetermined coordinate system. The thickness of the part is then determined as the distance between the top of the part and its seating plane.
