Title: Improvements in and relating to the automatic regulation of concentration of solutions
IPC: G05D7/01
Filed: 1943-04-15
Abstract: 570,844. Regulating liquid levels. HOLMES & CO., Ltd., W. C., and COOPER, C. April 15, 1943, Nos. 6017/43 and 3078/44. [Class 123 (i)] [Also in Groups XII, XX, XXVIII and XXIX] A variable is regulated e.g. through the agency of a loaded valve or switch by the discharge of water from a siphon, the air pressure in the head of the siphon being controlled by means of a suction device and an air leak from the atmosphere. Discharge of water from a totally immersed siphon 7 aspirates air from a system comprising a delivery siphon 1 when an air leak pipe 8 is sealed by liquid or a float on the liquid in a receptacle 9. An enlarged weir compartment of. siphon 1 may effect discharge at different rates according to the rise of liquid induced. The siphon system may be used to control the level of liquid in a tank by causing the siphon discharge to load and close a water inlet valve normally kept open by a spring or to cut off the steam supply or electric current to the machine driving the water pump. Alternatively, the vessel loading the valve may be evacuated by the siphon and caused thereby to close the valve. Specification 567,261., [Group XII], is referred to.

Title: Process and apparatus for recovery of material from waste paper
IPC: D21F1/66
Filed: 1977-02-14
Abstract: 1535001 Recovery of material from waste paper J M VOITH GmbH 14 Feb 1977 [13 March 1976] 06100/77 Heading B2H In a process for recovering fibrous materials from waste paper in which ink particles are removed by froth flotation, the fibrous material suspension from the flotation apparatus 10 is washed to remove other particles therefrom and the said other particles are subsequently sedimented to leave clean water. Waste paper is introduced into a pulper 1 and the pulp produced is fed to the flotation apparatus 10 via hydrocyclones 6 and 9 and de-inking devices 7 and 8. The froth from the apparatus 10 is quenched, passed to a centrifuge 26 and the water extracted therefrom returned to the apparatus 10 or passed to a container 24. The suspension of fibrous material from the apparatus 10 passes to a two stage inclined filter 16, where particulate impurities are washed out by water supplied through pipes 17 and 19. The waste water from the filter passes to the container 24 and then to a settling tank 28. The clean water from the tank 28 is re-used and the sludge dewatered in a centrifuge 31, the water from the centrifuge 31 being returned to the container 24. In a modification, the filter 16  is replaced by a rotatable screw in a filter casing.

Abstract: 727,848. Fastening railway rails. STAMM, K. March 5, 1953 [March 5, 1952], No. 6158/53. Class 104 (2). In a rail fastening in which at least one curved or stressed leaf spring is located on the rail flange and held down by fastening means anchored to a chair-plate or to the sleeper each leaf spring is concave downwards and is held down by the heads or nuts of two fastening means which project over the rail flange and are arranged one on each side of the mid point of the spring. As shown in Fig. 1, the rail 3 is secured to a wooden sleeper, with or without the interposition of a chair-plate 2, by the heads 8 of coach screws 5 bearing downwardly on a leaf spring 10. The sides of the ends of the springs 10 are downwardly turned at 11 so as to bear against the edges of the rail base. In the arrangement shown in Fig. 4 the rail 3 is, as shown on the left-hand side of the Figure, held down by nuts 13 screwed on the ends of a U-shaped member 14 or, as shown on the righthand side of the Figure, by flanged-headed bolts 15 screwed into sleeves 17 embedded in a reinforced concrete sleeper 18. The spring 10 is, as shown on the left-hand side of Fig. 4, held in position by a U-shaped member 19 one arm 23 of which engages the rail base edge and the other arm 21 of which engages the side of the spring 10 nearest the rail webs. As shown on the right-hand side of Fig. 4 the member 19 is apertured to fit the bolt 15 and at the inner end is downwardly bent to engage the side of the spring 10. In the arrangement shown in Fig. 8 an annular groove or bead 8 formed in the frusto-conical undersurface of the screw 5 engages a curved bead or groove formed in the upper face of the spring 10. The underside of head of screw 5 and the spring 10 may be in a corrugated form in a radial direction. Fig. 11 shows an arrangement whereby the spring 10 is held down by rail spikes 29 the heads 30 of which are bent over at 31 so as to engage the side of the spring 10 and the undersurfaces 32 thereof are concave or convex in the direction transverse to the rail to prevent longitudinal or transverse displacement of the spring. The springs 10 are initially compressed by a compression device, Fig. 10, the arm 26 of which is provided with a stepped portion 28 which abuts the rail base to limit the spring compression and to leave a specified initial clearance between the bowed portion of the spring and the rail flange.

Title: Improvements in apparatus for recording the duration of, and other data relating to telephone calls
IPC: H04M15/38
Filed: 1933-03-03
Abstract: 416,029. Recording particular operations. UNWIN, J. I., and UNWIN, R., Ashcroft, Chain Lane, Mickleover, near Derby. March 3, 1933, No. 6444. [Class 106 (iv).] Apparatus for recording data relating to telephone calls comprises a time-controlled drive for the record strip and a key or keys or equivalent devices for perforating, embossing or impressing type upon the strip one of the keys being adapted simultaneously to register the start of the call and to initiate the movement of the strip and one to register the termination of the call and stop the movement of the strip. The record strip 2 passes from a roll 3 over a clockwork-driven drum 1 to a roll 6 frictionally driven from the drum 1. The recording means comprise keys 19-25 formed as punches. The key 19 is depressed at the beginning of a call and punches a hole in the record strip and also removes a brake block 16 from contact with the milled part 1<b> of the drum. The drum then commences to rotate and is stopped at the end of the call by the depression of a key 20 which also punches the strip. Other data relating to the call are then recorded by the keys 21-25. The progress of time during the call is indicated by an arm 26 moving along a graduated slot 27<a> and having a one-way connection with the drum. After a predetermined interval a hammer 29 is released to strike a bell 28. The clockwork comprises a spring fixed at one end 1<a> to the drum and at the other end to a shaft 10 normally prevented from rotating by a pawl 15 acting through gearing 13, 14. A wheel 11 free on the shaft carries a pawl 11<a> engaging a ratchet wheel secured to the shaft 10. The wheel 11, which is thus stationary, gears with escapement mechanism 12 carried by the drum. The spring is wound by rotating the shaft 10 through the gearing 13, 14 and for this purpose the pawl 15 is disabled by a lever 15<a> and a pawl 15<c> is engaged with the periphery of the drum.

A cleaning or polishing device comprises a multifaced backing block around which is passed an endless band of cleaning material of much greater length than the periphery of the block, the device being such that when the block is rotated a new piece of the band may be brought into use. A square or triangular block 1 is supported between a forked extension of a handle 2 and a band of material 5, for example of cotton, wool, rubber or plastic, passes round the block and a support 6. The support is spring mounted to apply tension to the band. If the handle is raised slightly the end of the fork will move into the left-hand corner of a round or preferably square recesses 4 so that on pushing the handle forward the block will rotate bringing a fresh piece of the band into use. The faces of the block may be bevelled from a longitudinal centre line so that the block rocks slightly as the device is moved backwards and forwards. The block or a roller on the support 6 may supply liquid to the band through holes in the block or roller.
