Strainers comprising grids or gratings.- Apparatus for clearing the strainer gratings of water-power installations comprises a device moving along the bars and provided with teeth, which leave the bars automatically when they encounter a resistant obstruction. The apparatus is shown as applied to the arrangement for cleaning strainers described in Specification 174,070, which includes a perforated bucket e pivoted on a carriage m. The carriage moves up and down on the strainer bars x under the control of a cable a which is wound on a winch driven by an electric motor u on a carriage v travelling on a bridge w above the strainer. During the downward journey the bucket is held away from the bars and the detritus is pushed down by a scraping-plate m<5>. The bucket swings over at the bottom and lifts the collected detritus to the top of the strainer. The teeth 19 are supported in a U-shaped iron member 18 carried between cheeks 17 which are pivoted on flanges 14, the flanges 14 being themselves pivoted on the ends of the bucket e. A coiled spring normally keeps the cheeks 17 and flanges 14 in the relative positions shown in Fig. 2, the teeth 19 entering between the bars during the upward journey of the carriage, but when the teeth encounter obstruction, the cheeks are turned clockwise against the pull of the spring and the teeth are withdrawn from the bars. Certain of the teeth have ends 19<2> of trapezoidal shape so that when they come in contact with cross-bars x<1> of the strainer they will cause the temporary withdrawal of all the teeth from between the bars.

IPC: D04H1/732
Filed: 1959-01-22
Abstract: 947,203. Textile treating apparatus; forming fibre webs. BIRFIELD ENGINEERING Ltd. April 22, 1960 [Jan. 22, 1959], No. 2420/59. Headings D1L, D1N and D1R. A conveyer belt 6 mounted on rollers 6a intermittently edges a bulk supply of fibrous material in hopper section 1 on to a grid 7 of spaced parallel bars in conveyer section 2. Conveyer belt 8 having upstanding spikes 9 which project between the bars of grid 7 picks up fibrous material from belt 6 and delivers it over the top of roller 10. The bars of grid 7 curve upwardly away from the belt 8 at 7a at which point reciprocating comb 12, having its forward stroke against the direction of feed, removes any excess fibrous material picked up by spikes 9 and returns it to the bulk supply by gravity, thereby ensuring an even feed of fibrous material over the top of roller 10. From roller 10 belt 8 passes through a vacuum chamber with walls 18,19 at the base of which is rotatable foraminous condensing drum 20 connected by duct 22 to fan 23. The air flow strips the fibrous material from belt 8 and causes it to condense on drum 20 whence it is delivered in the form of a batt to feed rolls 26 which deliver it to spiked rotary teasing drum 29. An air blast from fan 34 passes through duct 33 tangentially below drum 29 and impels the fibres from the lower part of drum 29 along duct 33 to rotary fibre-condensing drum 36 on to whose surface the fibres form a layer in random state. This layer is delivered from drum 36 to feed rolls 39 and thence to opening drum 42. An air blast from fan 45 through duct 44 transports the fibres from the lower part of drum 36 along duct 44 to rotary condensing drum 46 whence they are delivered in the form of a lap to conveyer 52. From conveyer 52 the lap may enter a unit 55 having convergent flights (Fig. 2) of endless travelling mesh bands 59 and 60 of nylon, woven wire, perforated rubber or perforated metal passing at 62 through bath 58 containing impregnating liquids, e.g. dyes, latex, resin or synthetic plastic and then between squeeze rolls 66 and squeeze rolls 67, which may be embossed. From rolls 67 the lap is conveyed to means (not shown) such as an oven for drying-off and/or curing the impregnating agent. Alternatively, the lap may be delivered to a unit 5, Fig. 1, which corrugates the lap and applies a backing material, e.g. latex or liquid synthetic plastic or rubber to one surface, after which the fabric is cured and dried. The lap leaving the conveyer 52 may pass through unit 55, for dyeing, and the unit 5, for backing, in turn, and may be shaped before or during curing.

Title: Improvements in or relating to composite titanium pigments and methods of making the same
IPC: C09C1/00
Filed: 1936-01-27
Abstract: Composite titanium oxide-calcium sulphate pigments are prepared by hydrolytic precipitation of hydrated oxide from sulphuric acid solutions of titanium containing finely-divided calcium sulphate prepared by wet milling gypsum in the presence of solubility and crystallization depressing agents.  Suitable agents are calcium compounds, e.g. hydrated lime; sulphates, e.g. of sodium or ammonium; and organic colloids, e.g. glue, gelatin, agar agar, and gum arabic. All iron present in the gypsum may be brought to the soluble, ferrous, state by the addition of a reducing agent, e.g. sodium hydrosulphite, or ammonium, calcium, sodium, or zinc sulphite.  The slurry may be neutralized by hot dilute sulphuric acid and added to the hot titanium solution, the concentration of sulphuric acid (free and combined) being brought to 12 per cent if necessary, and the mixture boiled.  The precipitate is filtered, washed, dried and calcined at about 900 DEG  C.  The pigment particles are pseudomorphic after natural gypsum, and have an average particle size of 1,5 microns or less.ALSO:Finely-divided calcium sulphate is prepared by wet milling gypsum in the presence of solubility and crystallization depressing agents.
