Title: Improved manufacture of artificial carbonaceous blocks other than fuel briquettes
IPC: H05B7/085
Filed: 1942-06-02
Abstract: A mixture of carbon and binder is subjected to mechanical vibration of a high frequency, at least 6,000 vibrations per minute, compressed if desired, and then baked.  The mixture may be p  vibrated by immersing a vibrator therein, or by jolting the mould, and may be vibrated before or after it has been poured into a mould or into an electrode shell through which pass electrodes of the continuous self-baking type, e.g. the treatment may be carried out while the mixture is in a ladle.  As a mould is being filled, a vibrator immersed in the mixture in the mould may be gradually raised, or the mould may descend, or both may occur simultaneously.  The vibrator may be of the type used in vibrating high-grade concrete.  The mixture may be heated before being vibrated.  By the invention, a one-piece sector-shaped block constituting part of the wall of a furnace and a corresponding section of the hearth may be made.

The charcoal mav be covered with manganese dioxide and plumbago. A perforated zinc electrode a closed at the bottom surrounds the carbon electrode and stands in an outer vessel containing a solution of ammonium chloride, the inner wall of the zinc being lined with blotting paper, filter paper or felted material. In order to allow the electrolyte to evaporate within the pores of the charcoal agglomerate without saturating the same, the space between the agglomerate and the zinc electrode is filled with a jelly i consisting for example of starch and a solution of zinc chloride. The zinc electrode mav be of less thickness at the lower end than at the top and is closed by wax &c. j. Contact between the electrodes may be prevented by a cord carrying insulating beads h surrounding the agglomerate g. The carbon electrode f may be hollow and provided with perforations to allow access of air to the entire length of the agglomerate g which may also be formed with vertical passages. The agglomerate g may consist of two blocks held against the sides of a flat carbon electrode, and conducting substances such as graphite, metal &c. may be incorporated in the agglomerate to reduce the resistance of the cell. ln another modification discs of agglomerated porous carbon are threaded upon the carbon electrode, the discs being separated by discs of retort carbon, all of which may be provided with vertical passages. In a further modification the agglomerate is in the form of small pellets which project at both ends through the walls of a hollow carbon electrode, the inner ends of the pellets being formed with ribs or wings to increase the surface in contact with the air.

Abstract: 576,198. Oil filters. WILKINSON, J. W. April 25, 1944, No. 7706. [Class 46] An oil filter 17, Fig: 2, is secured to an engine block 16 by means of a pad consisting of three metal plates 25, 26, 27 shown detached in Fig. 5. The face of the block is provided with three openings A, B, 44, the opening 44 registering with openings 29 in the plates and with a conduit 21 in the filter 17. Openings A, B, register with openings 33, 34 in plate 27 which register with the ends of slot 32 in plate 26. This slot communicates with an opening 30 in plate 25 leading to a conduit 31 on the filter. In operation oil circulated in the engine flows through opening A, opening 33 in plate 27, across slot 32 and back to the engine through openings 34, B. Part of the oil is by-passed through the filter returning through conduit 21 and opening 44. The plate 25 is welded to a bracket 36 which is welded to the filter frame and is provided with holes registering with those on the plate 25. In a modification the plate 25 is omitted, and in a further modification the plate 27 is also omitted being replaced by the bridge portion of the bracket securing the plate to the filter. In the arrangement shown in Figs. 13 and 14, the plate 26 is formed with slots of the form shown and the plate 25 is provided with a spring-pressed valve 60 whereby the filter is by-passed when the pressure is too great. In this case there is only one opening in the face of the engine casing for the return of oil.

Abstract: 943,286. Cleaning printing press cylinders. E. GERICKE. March 3, 1961 [March 3, 1960], No. 7796/61. Heading B6C. The blanket cylinder 2 of a rotary offset machine may be cleaned by a pivotally mounted arrangement comprising a wick 10 and a wiper 11 having a resilient base 12 and a readily interchangeable cloth overlay 13. The wick extends into a chamber 9 of a two-chambered vessel 6 the other chamber of which contains a cleaning liquid 7 such as benzine. The chambers are interconnected by an orifice which is formed in the separating wall 8 remote from the opening through which the wick extends into the chamber 9. The vessel 6 with the wick 10, the wiper 11 and an operating handle are mounted on a shaft 5 and the arrangement is rotatable by the handle into three positions. In position " F " the wick is in contact with the blanket applying cleaning liquid thereto and in position " W " the wick is spaced from the blanket whilst the wiper assembly 11, 12, 13 is in contact therewith removing the used liquid therefrom. In the position " R " both the wick and the wiper are non-operative relative to the blanket surface but in this position, as in the position " W," the wick is soaking in the liquid which has entered the chamber 9 through the orifice in the wall 8. The amount of liquid absorbed by the wick for each cleaning operation is determined by the distance of the upper edge of the orifice in wall 8 from the opening through which the wick extends into chamber 9.
