Patent EP-0202796-A2 (EP)
Inventor: PAUL KERMIT D
IPC: B65G53/12
Filed: 1986-04-28
Abstract: A process and apparatus for pneumatically conveying solid particulate material which includes a vessel (1) or blow tank which is supplied with particulate material to be conveyed from a suitable source. A riser pipe (5) extends into the vessel (1) and has a material inlet (6) near the bottom of the tank with its other end flow connected to a transport line. A bottom discharge arrangement is also contemplated. Gaseous fluid under pressure is supplied into the vessel (1) to pressurize the vessel and entrain and convey material through the riser pipe (5) to the material transport line and to a remote use point. A by-passline (20) is provided for selectively connecting the pressurized inside of the vessel with the riser pipe/transport line at a point downstream of the inlet (6) for material. This by-pass line (20) serves to selectively vent gaseous fluid under pressure in the vessel (1) to the material conveying line (5) when system pressure exceeds a predetermined limit. This results in an increase in air flow being supplied to the conveying line (5) to thereby reduce the material to air ratio in the conveying line and control the conveying rate through the conveying line. Adjustment of the value of the predetermined pressure can be used to adjust the material conveying rate. A low level sensor (40) is provided in the vessel (1) for actuating a control mechanism to change the predetermined pressure at which the by-pass line (20) will open to thereby permit gas under pressure in the vessel to be used for emptying the vessel.

Abstract: A receiver for deciding which signal points were sent from a transmitter based on corresponding noise affected signals received via a distorting channel, the noise affected signals carrying information about a particular sequence of encoding states occupied in a succession of time intervals by a finite state process having a finite number of possible encoding states, the receiver including modifying circuitry for generating a plurality of different modified versions of each received signal, and a decoder for deciding which signal points were sent based on estimating a particular sequence of decoder states by storing a number of path histories of previous signal points and using the modified versions to , extend the path histories, the different modified versions of each received signal numbering fewer than the number of stored path histories. In other aspects, the constellation of signal points is partitioned into decision subsets, each possible transitions from a possible decoder state are associated with a decision subset, based on the signal points in the path histories, and each of the modified versions is associated with one of the decision subsets; there are fewer modified versions than the number of decoder states; and the decoder states number fewer than the number of decoder states in an optimum trellis decoder.

Abstract: A microfinishing apparatus and method is disclosed particularly useful for microfinishing workpiece surfaces such as are found in journal bearings and cylinder bores. This invention improves over conventional machines and methods wherein coated abrasive tape (30) is brought into contact with a relatively rotating workpiece surface and is pressed against that surface by an elastomeric plastic insert. (36) According to this invention, the insert (36) is made from a relatively rigid substance such as honing material stone. Since the insert (36) is made from a rigid material, the insert surface shape is generated in the workpiece surface and therefore geometry corrections in the workpiece surface can be accomplished. In alternate embodiments of this invention, the rigid inserts (36) have relieved portions or noncylindrical surfaces such that a desired surface profile in the workpiece surface is generated. In another embodiment, one or more flexible inserts are added to the rigid insert enabling the fillet radius area to be microfinished. In yet another embodiment, coated abrasive tape (30) includes a multiplicity of perforations thereby permitting the exchange of cutting fluids between the surfaces. Finally, several means (60) for supporting the rigid inserts (36) for slight rotation relative to the workpiece surface are described.

Abstract: A coextrusion head for the continuous production of laminated tubes to be used as parisons in blow molding. The tubes consist of a plurality of layers of synthetic resins. The synthetic resin layers include one or more supporting layers, usually a barrier layer, and adhesive layers as necessary. The layers are brought together by axial, annular feed passageways within the coextrusion head prior to the laminated tube being extruded through a nozzle in the head. Frequently one layer, generally the barrier layer, has different flow characteristics than those of the other layers, whereupon structural defects can arise in the formed tube. The apparatus described forestalls such structural defects by feeding the various layers into confluence in a manner that precludes, or sufficiently minimizes, the time layers having differing flow characteristics have contact with feed passageway walls while in confluence. As a result, shear stresses within or between the individual layers is avoided and the tube so produced is free of structural defects.

Measurements derived from circumferentially successive elements are combined, such as by summing to establish a desired overlap. In the described embodiment a single lateral array of small electrodes is used to inject survey currents into the borehole wall and each current is measured. Measurements derived from pairs of successive survey currents are then summed to provide the desired overlap.
