Patent number: 4689895Abstract: Disclosed is an apparatus for providing a shower of fog onto a web or a machine component in contact with a web. The fog, which has a temperature lower than the temperature of the surface of the web or the machine component to be cooled, is applied to the surface and is caused to evaporate by the difference in the temperatures. A supply of dry air is supplied to transport the evaporated fog from the region surrounding the surface to be cooled. Fog may be generated through the use of an air-atomizing nozzle which propels water and compressed air through a small orifice under pressure to create an atomized mist or fog. The fog may also be generated through the use of an ultrasonic transducer which expels fine droplets of water from its surface by means of a high-frequency oscillating transducer motion. In one embodiment, the fog may also be generated in controlled specified quantities locally at each nozzle as required to provide for a controllable fog application rate across the full apparatus width.Type: GrantFiled: February 28, 1986Date of Patent: September 1, 1987Assignee: Thermo Electron-Web Systems, Inc.Inventors: Bruce F. Taylor, Kenneth G. Hagen

Patent number: 4691314Abstract: A data telecommunications system and method is provided for sending a data stream of characters in distinct data packets between two units of data terminal equipment (which can be either terminals and/or computers) connected over communication lines. A modem is connected between each unit of data terminal equipment and the communication lines, and one initiating modem includes a means for changing the packet size of the data which is transmitted. The receiving modem checks the packets for errors, and if errors are found, the packet is retransmitted. The initiating modem counts the number of transmissions of data packets as well as the number of retransmissions of data packets. A ratio of retransmissions to transmissions is used to determine the optimum packet size. The packet size is continually subject to change as the ratio changes during transmission.Type: GrantFiled: October 30, 1985Date of Patent: September 1, 1987Assignee: Microcom, Inc.Inventors: Lewis A. Bergins, Anthony P. Amundson, Jerry Falk

Patent number: 4689203Abstract: The invention concerns a centrifuge intended for use in mainpulating liquid batches on an analytical scale. The centrifuge consists of a body (2) rotatable about its axis (1) provided with input and output conduits (8,9,11) and presenting the essential feature that therein are contained two parallel, circular arc-shaped volumes (3,4) located at different distances from the axis (1) of the body (2) constituting the center of curvature, and communicating with each other through a narrow gap (7) so that when the body is rotating, the heavier components of the liquid accumulate in the volume (4) further away from the axis, and the lighter components accumulate in the volume (3) closer to the axis, whereafter one of these two volumes can be emptied through a conduit (12), while the surface tension acting in the gap between the volumes keeps the liquid in the other volume in its place. The centrifuge of this invention is particularly appropriate for separating blood plasma from the red and white cells in the blood.Type: GrantFiled: January 11, 1985Date of Patent: August 25, 1987Assignee: Fluilogic Systems OyInventors: Niilo Kaartinen, Teuvo Sorvari

Patent number: 4685221Abstract: Disclosed is a steam-shower apparatus and method including a supply of steam which is fed through a Coanda nozzle and along a path running parallel with one surface of the apparatus. The sheet to which the steam is to be applied runs parallel to this same surface of the machine, but in a direction opposite to the direction of the flow of steam. The sheet travels along a path spaced slightly from the surface of the machine, and the flow of steam runs the entire length of this surface heating the sheet as it flows in the opposite direction. The apparatus may be divided into several sections so that the sheet may be profiled along certain regions which are defined by these sections. In addition, means are included for altering the volume of flow to any one of the particular sections.Type: GrantFiled: February 28, 1986Date of Patent: August 11, 1987Assignee: Thermo Electron - Web Systems, Inc.Inventors: Bruce F.
