Abstract: 451,697. Wall coverings. CLEEFF, J. VAN, 453, Mathewesserlaan, Rotterdam, Holland. Nov. 7, 1934, No. 32042. Void [Abridged as open to inspection under Sect. 91 of the Acts, May 11, 1935]. [Class 20 (iv)] [See also Group XVI] Wall coverings are made by embossing a textile fabric impregnated with a fixing-agent by a pressing or rolling operation, the depressed part of the covering being given, if desired, a ribbed appearance. The fixing- agent preferably consists of dextrine, or a mixture of glue and borax, and the fixing agent may also serve as an adhesive. Means for rendering the material waterproof may be added to the fixing-agent. The material may be printed before or after embossing, and the fabric may be dyed by the Indanthren method. One-ply jute yarn 1, is embossed between heated plates or rollers, one plate or roller bearing a design in high relief, the counterpressure member being hard and smooth. The surface of the relief member may be formed to produce smooth depressions 3, or so as to produce ribbed depressions. The effect may be varied by using a linen twill, herring-bone twill, or other weave.

The tine 6 may rise from the front of the share 18 that completes the separation of the furrow slice. The separated furrow slice is turned by a disc or mouldboard 19 &c. A bar-pointed share may be used. A slide or roller 20 prevents the furrow slice. from riding up the tine, and a slide plate 21 extends into the cut made by the coulter 5 and forms a guide for the plough. The plate 21 may be shaped at its end to form a coulter. The tine 6 may have a rounded upper edge of polished rustless material. The edge of a triangular plate may be used instead of a tine. A number of coulters, tines, shares, and mouldboards may be. provided on a single frame, the tines being located behind and centrally between the coulters.

The articles in the spraying position are rotated by a pulley driven by the shaft 11 engaging a pulley on the holder.  The holders are raised by a cam when inoperative so they are not rotated and are out of contact with a stop 20 to operate the spraying device.  The spraying device is supplied with compressed air by a cam 25 on the shaft 11 which operate a valve 26.  The spraying device is moved vertically on a column 28 by a chain and linkage controlled by a cam 31 on the shaft 11.  The contour of the cam may be varied to alter the rate of movement. The spraying device may be mounted for arcuate movement or for oscillation the latter by a linkage connecting the column with the periphery of the cam 25.  To limit the area of the article sprayed one or more rotatable discs may be mounted between the article and spraying device.  The articles may be dried, baked, printed upon and covered with flock.  The flocking chamber may be situated beside the spraying chamber and may have swing doors for the passage of articles therethrough and an air jet for directing the flock and for withdrawing unused flock.  The conveyer may be straight instead of circular.

The "impact error" of any point on the target is defined as the potential difference between that point and the target centre due to non-orthogonal beam incidence. The defect increases towards the target periphery, and is marked in Sb 2 S 3  or Se layers. Permanent magnetic focusing may be employed, the external and/or internal diameters of the focusing coil may be stepped, and the deflection coil unit may be external to coil 5 (Fig. 3, not shown) and may be in the main lens plane which is nearer the target than the diaphragm. The magnetic return path may be via a laminated ring member with polepieces and magnetic wire coil 7 provides mutual screening. Screening between the focusing coil and deflection coil unit (Fig. 3) may be by an axially slotted tube of non-magnetic electrically conductive material or an insulating tube with attached axially extending conductor paths. Target 2 is a multi-diode Si target and coil 5 in Fig. 1 has increased winding density towards the target. Aperture and beam diameters are disclosed, cathode 4 may be impregnated dispenser type, and a fine-mesh field electrode may be present.

In a process for the purification of chlorine gas the discharge electrodes of a wet electrostatic precipitator are wires of or coated with titanium or titanium nitride and the collector electrodes are of a non-corrodible material, such as synthetic resin, the flow of liquid over which is used as a conductor and is held at earth potential by means immersed in the precipitate where it discharges from the collector electrodes. The discharge electrodes are wires 2 hung from a rail 10 with tensioning ceramic weights. The collector electrodes 1 discharge liquid precipitate into ducts 4 of resinous material in which cables 5 of graphite coated with platinum, ceramic, or fibre glass facilitate earthing of the electrodes. The separate cables 5 are interconnected by platinum wires one of which is passed out of the precipitator casing through an insulator to earth. The collector electrodes 1 end in alternately bent tabs 3 secured to the ducts 4 and the electrodes are roughened to ensure good adhesion between their surface and the precipitate. The gases to be purified pass upwards between the electrodes and water may be sprayed downwards to facilitate collection from the electrodes. As shown in Fig. 2b the collecting electrodes may be tubular with their bottom edges immersed in liquid in the collecting trough 4. The earthing cables 5 in this arrangement are rings connected into a lattice by platinum wires. The collecting ducts 4 may be replaced by tubes or sponges of synthetic resins.

Abstract: 632,077. Pneumatic separating. RUEPP, T. Dec. 12, 1945, No. 33633. [Class 117] Finely-divided materials to be screened are fed from a shoot into rough-dressing chambers 3, Figs. 1 and 2, which are separated by partitions from chambers 10 with inclined bases. Air at high velocity flows up through the chambers 3 carrying the lighter particles into an expansion chamber 7, where some of the lighter particles separate out, being collected in the chambers 10. They are discharged through an outlet 11. In a modification shown in Fig. 3 the rough-dressing chambers 14 are caused to vibrate by means of an unbalanced rotating shaft 23. The chambers 14 have inclined base plates 15 formed with perforations much larger than would pass the coarsest grains and through which air is blown upwardly. The coarsest grains fall through the perforations and the lighter particles are carried up to the expansion chamber when some particles separate out and are collected in chambers provided with inclined plates 17 for discharge through shoots 16. Each of these shoots terminates in a point to distribute the particles over the entire area of a chamber 18 from which finer particles are carried by an air current through an outlet 19.
