[Class 46.] In paper making the longer fibres are separated from white water by a continuously moving screen of mesh which, unobstructed, passes the shorter fibres and wood flour, liquid being passed through the screen at one portion of its path, paddles or blades being reciprocated or oscillated relatively to the screen continuously to agitate the fibres on the inflow side of the screen to maintain the flow through it and delay the deposition of the fibres, and the longer fibres which do not pass through the screen being collected from another part of the screen and discharged. A drum 1, Fig. 2, rotated in bearings 2, 3 by reduction gearing 40, Fig. 3, has spiders 7 intermediate of end-plates 4, 5 supporting a coarse wire-screen or perforated drum 11 covered by a fine wire-screen 12 in sections clamped by rims 13 and, at their edges, by bars 6. The drum is divided by partitions 18 with openings 19 relatively 'displaced angularly and a hollow shaft 8 carries agitators 20 which may have spray jets 24 and are oscillated by an eccentric 42 &c., Fig. 3, the shaft 8 being also reciprocated endwise owing to a screw thread 45 &c. A spray pipe 36 above the drum may also be oscillated from an arm 46 on the shaft 8. White water &c. enters by a pipe 32 and compartment 28 having a weir 33 and passes through a float-controlled valve 30 to the drum, the fibre &c. being deposited and the water flowing through the screen into a compartment 26 and over a weir to an overflow box 50, the fibrous deposit being agitated in the successive compartments to cause the wood flour &c. to pass through the screen, the larger fibres being finally washed off by the spray 36 and passed into a shoot 25.

A winding apparatus for use with a reel 313, Figs.1 and 2, having a flange 465, 467 at each end, comprises a shaft-300 mounted in a bearing 425 that can be moved by a slider 426, 427 to push the shaft 300 through the reel 313 and into a further bearing 406. The shaft 300 has a splined section 430 on which is mounted a sprocket 432 driven through a sprocket chain 433 from a motor 302. The shaft 300 carries a disc 418 on which is a rubber lining 420 such that when the shaft 300 is pushed through the reel and into the bearing 406 the reel 313 is rotated by frictional engagement of the lining 420 with radial vanes 464 on the flange 465. The pressure exerted by the disc 420 also causes vanes 464 on the flange 467 to press against a rubber sheet 414 coating a pad 416 Fig. 2 so as to turn an annulous 413 rotatable on the bearing 406. The rim 413 of the annulus carries a pivoted clamping member 468, Fig. 9, pivoted about a pin 470, the clamping member comprising a weight 471 at one end and a clamp arm 468 at the other end. As the reel 313 speeds up to full speed the weight 471 is urged outwardly to rock the clamp arm 468 inwardly. When a thread to be wound is transferred to the empty reel from a co-axial fully wound reel pressed against a futher annulus 413<SP>1</SP>, it becomes wedged between the clamp arm 468 and the annulus 413 and the thread extending between the annulus 413 and the annulus 413<SP>1</SP> is then cut by a knife (not shown). When the reel 413 is fully wound and brought to a halt the clamp arm 468 can be lifted to release the thread. Automatic reel changing. When a reel is full its shaft, for example shaft 300, is withdrawn and the reel then rolls down a ramp 461, Fig. 6. Empty reels 313 wait on a second ramp 440 and are picked up in turn by piston actuated means 455 for presentation to the shaft 300.

The tube contains a mercury column 4. By suitable choice of the values and positions of the resistors 8 the resistance and angular position may be related by any predetermined law, e.g. a cosine law. Increased sensitivity at certain angles may be achieved by using more terminals or varying the tube diameter at certain parts of the tube, or by making it less curved at one part (Fig. 4, not shown). A continuous instead of a stepped indication may be achieved by threading a resistance wire through the length of the tube. Plug-in resistors 8 may be used so that the device may be easily adapted for different jib lengths.

Abstract: 1,105,625. Signalling by visible signals. G. R. FOUNTAIN. 18 July, 1966 [7 May, 1965], No. 19397/65. Addition to 929,851. Heading G4F. [Also in Divisions F4 and H4] A portable hailer such as described in Specification 929,851, has switch contacts for energizing a socket for an electric lamp 14 which when energized produces a visible signal. Preferably a lamp reflector 13 acts as the socket and is located so that the hailer emits a beam of light having an axis substantially parallel to that of the loudspeaker. A three position switch 7 is provided. In its first position a hooting note, derived by a feedback connection and an oscillatory circuit, is emitted together with a narrow beam light signal when a master push bar switch 17 is depressed. In the other two positions of the switch 7 the lamp 14 is not energized. In an alternative construction the lamp 14 is connected directly across the battery and the push bar switch 17 so that whenever the switch 17 is operated the lamp 14 is energized. Operation of the switch 17 may energize the lamp 14 only when the contacts of an independent switch (not shown) are closed. The visible signal can be used for pre-announcement purposes and to send a message by means of Morse code.
