Title: An improved process for treating trade waste waters to clarify and sterilise the same and to extract fats therefrom
IPC: C11B13/00
Filed: 1922-02-07
Abstract: 197,033. Raeve, A. J. de. Feb. 7, 1922. Recovering fats and oils from waste waters.- Grease and other matter is separated from woolwashing or other waste water by successive treatment with alkali, chlorine, and acid. Wool-washing waters are treated while fresh and warm with sufficient lime to convert the contained carbonate of soda into caustic soda, then boiled, and afterwards allowed to cool and settle. The liquid is transferred to a second vat for treatment with chlorine. Acid is subsequently added in sufficient quantity to neutralize the hypochlorites formed, and grease and soaps are removed by skimming. The liquid may be finally clarified by filtration through a bed of clinker or sawdust. The recovered grease may be dehydrated by reemulsifying it with clear water containing soda in a heated vat fitted with a stirrer, then allowing separation to take place slowly at a temperature slightly above the melting point of the grease. Liquids from abattoirs can be treated in a similar manner. The sludge obtained in the first stage of the treatment can be worked up with clay or loam-for use as manure. Sodium chloride may be added to the liquid in the first vat in sufficient quantity to produce the required amount of chlorine if the liquid is subjected to electrolysis in the second vat. Suitable apparatus for this electrolytic treatment comprises a cell with transverse partitions 14, Fig. 2, which cause the liquid to take a sinuous course as it flows through from end to end. The anodes 20 and cathodes 22 are of the form shown in Figs. 6 and 4 respectively, the cathodes differing from the anodes in that their terminal lugs 23 are cranked. Insulating separators 24, Fig. 5, are arranged between them. The flowing liquid is agitated by air jets from pipes 17.

Title: Improvements in Machines for Spooling Yarn or Thread.
IPC: B65H54/28
Filed: 1916-03-13
Abstract: 101,581. Dewhurst & Sons, J., and Preston, W. March 13, 1916. Thread-spooling machines.-The traverse and shaper mechanism is controlled by means governed by the bevelled edges or flange of the spool or bobbin on which the thread &c. is being wound. The traverse rod 2 slides in bearings 7 in the frame 1 and carries, mounted loosely upon it, a piece 8, to which are adjustably bolted arms 9 having threaded half-caps 11 to engage the righthanded and the left-handed portions of the traverse screw 3. Arms 12, 13 are secured to the rod 2 and are also supported by a rod 22 sliding in bearings 23 in the frame 1. The piece 8 is normally kept midway between the arms 12, 13 by springs 17 adjusted by nuts 16 on screws 15. A spring arm 18 with a finger 19 at the free end is secured to the piece 8. The finger 19 is oval in cross-section; it normally engages either the upper or the under surface of a projection 20 on a carrier 21 sliding on the rod 22, and holds one or other of the half-caps 11 in engagement with its section of the screw 3. The carrier is prevented from turning by a roller 24 engaging a slot in the framework 1, and is normally kept midway between the bosses of the arms 12, 13 by springs 29 adjusted by nuts 27 on screws 28. A lever 31, pivoted at 32 to a bar connecting the arms 12, 13, engages pins 34, 33 on the carrier 21 and the piece 8. As the traverse guide comes near to one bevelled edge of the bobbin &c., the finger 19 engages with an arm 37, controlled by springs 39, and pivoted to a bracket secured to the frame. The arm is lifted and releases the finger 19 and projection 20 from a catch 41 by means of a finger 44 and a contact screw 44a. When the guide makes contact with the bevelled edge of the bobbin &c., movement of the bar 2 is stopped, but the piece 8 continues to move and rocks the lever 31, disengaging the finger 19 and projection 20 and allowing the finger to escape to the other side of the projection. This brings the other half-cap 11 into engagement with its section of the screw 3 and reverses the movement of the guides. The springs 29 return the lever 31 to its normal position, and the springs 17 bring the piece 8 back to its central position between the arms 12, 13. Safety stops 46 are provided in case the bobbin is filled with thread &c. to the level of the flanges. Specifications 749/88 and 4288/95 are referred to.

Title: Improvements in current-limiting electric cartridge fuses
Inventor: KOZACKA FREDERICK JOHN
IPC: H01H85/045
Filed: 1952-02-13
Abstract: 701,076. Fusible cut-outs. CHASE-SHAWMUT CO. Feb. 13, 1952, No. 3838/52. Class 38 (1) In a current-limiting cartridge fuse of the type comprising a fusible link surrounded by an arc-quenching filler, e.g., quartz sand, which is converted upon blowing of the fuse into a hot semi-conducting fulgurite, steps are taken to cool the fulgurite by convection and render it non-conductive, by means of the gases produced by the fuse blowing. The Specification describes the theory underlying the construction. An inner insulating casing 1 encloses a fusible link 2 of silver surrounded by quartz sand 3 and having a number of perforations 2a. An outer insulating casing 4 forms with the casing 1 an annular chamber 5 connected to the interior of the casing 1 by a number of (e.g., four) radial vents 1c. A cellulosic tape 6 prevents egress of the sand 3 from the casing 1. On low-current interruption the link 2 vapourizes and the gas pressure produced breaks the tape 6, and gases flow along the casing 1 towards its centre and through the vents 1c into the chamber 5, thereby cooling the fulgurite formed by the sand 3 and preventing post-interruption failure of the fuse. In the case of short-circuit interruption, there is less heating of the fuse and the circuit is successfully interrupted without, in general, breakage of the tape 6 and the cooling effect of the gases. To withstand the high pressures, the casings 1, 4 are closed by triple pairs of metal caps 7a, 8a, 9a. In a modification Fig. 3 (not shown), a tin rivet is inserted in one of the perforations 2a towards one end of the link 2, the rivet forming with the silver link 2 a low-melting-point alloy where arcing is initiated upon low-current interruption, the rivetcarrying end of the link being surrounded by a gas-producing filler, e.g., chalk, separated by a partition from the quartz sand.
