Abstract: 191,738. Liese, H. [Firm of]. Jan. 10, 1922, [Convention date]. Ventilating mines.-The Specification as open to inspection under Sect. 91 (3) (a) comprises a description of apparatus for regulating a gas to a predetermined pressure or specific gravity, or for the regulation of the ventilation gases in a mine, or for controlling the carbonic acid content of the smoke gases of a fire. A tank is supplied with water through a pipe 2, Fig. 1, (Cancelled), the water overflowing at a partition 3 to discharge orifices 18. A cover 11 has depending partitions 12 forming spaces above the water level, to which gases may be introduced by pipes 16, 17. The spaces are fitted with open-ended tubes 4, 5 which slide through the bottom of the tank and are bent at the lower end to form a water seal. The tubes rest on cams 10, 19 on the shafts 9, 13 of water wheels 8, 15. The pipe 6, leading from one orifice 18, and the tube 4 discharge on to opposite sides of the water wheel 8, while the pipe 7 and tube 5 discharge similarly to opposite sides of the water wheel 15. In the state of balance, the levels of water in the spaces are such that onefcurth of the supply is discharged at each of the pipes 6, 7 and tubes 4, 5. The shafts 9, 13 are fitted with pointers the positions of which correspond with the position of the tubes 4, 5 and hence with the pressures in the spaces. In another form the movement of a water wheel operates a throttle valve in a pipe thus regulating the pressure. In the form adapted for use in mines, a tank has several spaces each in communication with one of the various levels of the mine, and the tank is fitted with glass peep-holes by means of which water levels may be observed. The overflow pipes from the spaces cause the operation of safety devices when the water stands at certain levels. This subject-matter does not appear in the Specification as accepted. Specification 163,015, [Class 106 (ii), Dynamometers &c.] is referred to.
Patent GB-968332-A (GB)
Title: An organic chromium tanning agent
Inventor: BANNER ROBERT GERALD
IPC: C14C3/02
Filed: 1961-01-09
Abstract: The invention comprises a leather tanning agent produced by adding slowly, with agitation, an aqueous solution of lignic sulphonic acid to an aqueous solution of a hexavalent chromium compound consisting of chromic acid or an alkali metal bichromate in an amount of 25-50% by weight of the lignin sulphonic acid (expressed as "lignin solids", herein defined) to yield a reaction product containing chromium, at least 50% by weight of which is in a non-ionic form. Lignin sulphonic acid refers to lignin sulphonic acid obtained from neutralized sulphite waste liquors which, generally, have been neutralized with Ca or Mg salts and when spray dried give water soluble lignin sulphonate or "lignin solids". The term "non-ionic" means chromium which carries substantially no electrical charge as detectable by ion exchange techniques.  The preferred chromium compounds are the bichromates, particularly sodium bichromate.  The lignin sulphonic acid may be used as such or may be formed in situ by acidifying a solution of lignin solids with a mineral acid, e.g. with 35% by weight of H2SO4.  Suitably a 50% by weight sodium bichromate solution is added to an aqueous solution of lignin sulphonic acid over a period of 1-2 hours with continuous agitation.  The resulting solution has a pH of about 2, and may be used as such, but preferably is partially neutralized with alkali to raise the pH to 3.0-4.5, especially 4.0.  The solution can be used as such for tanning (see Division C6) or spray dried at an elevated temperature.  Example (1) describes the preparation of a solution containing 70.7% non-ionic chromium from sodium bichromate.ALSO:Leather is tanned by treatment with a composition containing chromium at least 50% by weight of which is in a non-ionic form obtained by adding slowly, with agitation, an aqueous solution of lignin sulphonic acid to an aqueous solution of a hexavalent chromium compound consisting of chromic acid or an alkali metal bichromate in the amount 25-50% by weight of the lignin sulphonic acid (expressed as "lignin solids").  "Lignin solids" refers to the material obtained by spray-drying the lignin sulphonates formed by neutralizing sulphite waste liquors with Ca or Mg salts. The tanned leather may be retanned with known tanning materials. Example (2) describes the tanning of pickled steer hides. In Examples (3) and (4) the thus-tanned leather is retanned with a chrome sulphate and vegetable tannage respectively.  In Example (5) the leather from Examples (2) and (3) is fatliquored with a cationic-non-ionic animal type fat liquor.  Examples (6) to (8) describe the properties of the leather tanned by the present process.
