Title: High effiency continuous separation process
IPC: B01D53/04
Filed: 1983-08-08
Abstract: An extract component is separated from a raffinate component contained in a feed mixture by a process in which a unidirectional fluid flow system is maintained through a series of separating units through which the components travel at different rates. A component concentration distribution is established within the system of units and divided into specific zones. Feed and displacement fluid are passed into the inlets of two of the units and extract and raffinate are taken as the entire streams from outlets of two of the units all at appropriate points on the component concentration distribution. Other inlets and outlets of the various units lying in the same zone are interconnected. At the appropriate times the inlets and outlets are shifted so as to simulate movement of the units in a direction co-current with the fluid flow and thereby enable the inlets and outlets to continually lie in the appropriate zones. Zones may be combined as zone pairs, each such pair thereupon being considered a single continuous zone.

Abstract: A filter bed clarifier comprising a tank (1), which consists of an upper, cylindrical part (2) and a lower, tapered part (3) and which is provided with a centrally disposed feed pipe (11) for the liquid to be clarified. The feed pipe has an outlet leading into the tank at the top opening (7) of the circulating/mixing cone (6) disposed in the lower, tapered part of the tank. The top opening is larger than the outlet opening (12) of the feed pipe so that the sludge being discharged from the feed pipe draws sediment flocs from the lower part of the bed, thus causing internal circulation of the sediment. The apparatus is especially suitable for clarifying green liquor.

Inventor: TROKHAN PAUL DENNIS
IPC: B29C35/08
Filed: 1991-06-26
Abstract: A backside textured papermaking belt is disclosed which is comprised of a framework and a reinforcing structure. The framework has a first surface which defines the paper-contacting side of the belt, a second surface opposite the first surface, and conduits which extend between first and second surfaces of the belt. The first surface of the framework has a paper side network formed therein which defines the conduits. The second surface of the framework has a backside network with passageways that provide surface texture irregularities in the backside network. The papermaking belt is made by applying a coating of photosensitive resinous material to the reinforcing structure and pressing the reinforcing structure into a deformable surface, so that the deformable surface forms protrusions which exclude resin from certain areas which when cured will lie along the backside of the belt, and then exposing the photosensitive resinous material to light of an activating wavelength through a mask which has transparent and opaque regions. A process for making paper products is also disclosed which involves applying a fluid pressure differential from a vacuum source through the belt to a partially-formed embryonic web of papermaking fibers. The fibers in the embryonic web are deflected into the conduits of the papermaking belt by the vacuum pressure while the papermaking belt and the embryonic web travel over the vacuum source. Following the deflection, the paper web is impressed with the paper side network of the belt, and dried to form the final product.

Abstract: 1,071,941. Sawing; woodworking. W. PREWO, [trading as WILLI PREWO WERKZEUGUND MASCHINENFABRIK]. Feb. 4, 1965 [April 27, 1964], No. 4897/65. Heading B5L. A woodworking machine comprises a machine table 1, an upper cutting unit 2, adjustable along transverse grooves 5 in the table, a vertical lower tool spindle 9 mounted in the machine table, and a stop-bar 10 adjustably fixed in longitudinal grooves in the machine table. The machine also comprises a circular saw 4 and a feed-wheel 3 carried by beams 6, 7 which are adjustable about posts 3a, 4a between operative and out-of-the-way positions. The cutting unit 2 is adjustable along cross-grooves 5, 5a so that its spindle 2a may be coaxial with the lower spindle 9. The groove 5 may be arranged in a slide 32 which, with the cutting unit secured thereto by a toggle screw 8, can be removed from the operating area of the machine table 1 and placed on a receiving plate 33. When the unit is again required to be operated, the slide is replaced on the table abutting an edge 32a so that the tool is in position without requiring further adjustment. The machine has two stop-bars 10 which are longitudinally spaced on the machine table and are of ground steel. Each bar is connected by a pair of links 11, Fig. 2, to a contact rail 12, the bar being adjustable relative to the rail by a screw 13. A clamping plate 22 is disposed above the rail and bar and a screw 19 is disposed in the rail and has a T-member 16 at its lower end for engaging a longitudinal groove in the machine table and a toggle nut 21 which serves both to clamp the rail to the table and to clamp a link 11 to prevent movement between the rail and table. The assembly of stop-bar and contact rail may be mounted on a plate 26, Fig. 11, connected by a pivot 27 to a plate 25 adapted to be fixed to the machine table, a screw-and-nut arrangement 28, 29 being provided to adjust the angular position of the stop bar and a surface 30 of the plate 26 which supports a workpiece to be machined. The receiving plate 33 for the cutting unit when removed from the machine table may be fixed to the table or be on a separate stand 35, Fig. 5, the plate being adjustable about a pivot 39 and vertically adjustable by a spindle 37 and hand wheel 38. The plate may also be rotated through 180 degrees about a vertical axis so that the cutting unit may operate on a further machine table. The machine table 1 is provided with channels 41, 42, Fig. 6, through which shavings produced during operation of the machine fall to the rear of the machine. If only the lower spindle 9 is being used, the opening 40 of the channel 41 may be closed by a cover 43. A roller table 45, Fig. 1, is traversable along a rail 46 and is adjustable transversely of the rail. The table has a pair of apertures 57 in which posts 50, Fig. 7 and 9, may be fixed, each post having an angularly adjustable stop-bar 54 and arms 51 carrying clamps 52 for workpieces 49 which can be moved past the tools for tenon- ing or cutting.

IPC: H05B3/56
Filed: 1975-12-27
Abstract: A beam of charged particles is deflected in a closed path such as a square, for example, over a cross wire grid at a constant velocity by an X Y deflection system. A small high frequency jitter is added at both axes of deflection to cause oscillation of the beam at 45 DEG to the X and Y axes. From the time that the leading edge of the oscillating beam passes over the wire until the trailing edge of the beam passes over the wire, an envelope of the oscillations produced by the jitter is obtained. A second envelope is obtained when the leading edge of the beam exits from being over the wire until the trailing edge of the beam ceases to be over the wire. Thus, a pair of envelopes is produced as the beam passes over each wire of the grid. The number of pulses exceeding ten per cent of the peak voltage in the eight envelopes produced by the beam completing a cycle in its closed path around the grid are counted and compared with those counted during the previous cycle of the beam moving in its closed path over the grid. As the number of pulses decreases, the quality of the focus of the beam increases so that correction signals are applied to the focus coil in accordance with whether the number of pulses is increasing or decreasing.
