Title: Improvements in cream separator driving means
IPC: B04B9/08
Filed: 1928-03-20
Abstract: 297,290. Webb, W. March 20, 1928. Driving.-A cream separator driven by a belt has fast and loose, pulleys B, C on the spindle A. The fast pulley B is tapered so that its diameter increases with distance, from the loose pulley C, and a helical groove extends round its surface as shown. The shifting means for the belt D consists of two rings E worked by a screw rod F with a handle J. The thread on the rod F to the right of the collar f has a smaller pitch than the thread to the left of the collar f, so that the two rings E move at different rates. The belt is shown in Fig. 1 on the loose pulley C; when the handle J is rotated to shift the belt, the left hand ring E moves quickly over the fast pulley B and the belt is moved slowly on to the pulley. The engagement of the belt and pulley will be gradual and will be retarded by the helical groove; shock in the transmission will be diminished by the facility with which the belt will slip on the screwed and tapered surface.

Title: Improvements in the treatment of waste sulphuric acid and manufacture of sulphates and of absorptive carbon therefrom
IPC: C01B17/90
Filed: 1934-03-22
Abstract: Sulphuric acid containing dissolved organic matter is concentrated to not less than about 68--72 per cent H2SO4 and then heated under pressure to a temperature above its boiling point at atmospheric pressure, whereby easily filterable carbon is formed.  Preferably, the acid is concentrated at atmospheric or reduced pressure to about 70 per cent and heated to not less than 175--180 DEG  C. for \ba1/4\be--2 hours.  The mixture of acid and carbon may be reacted with metals, oxides, hydroxides, or salts, including minerals and ores, to form sulphates such as ammonium, potassium, sodium, magnesium, aluminium, ferrous, ferric, copper, and zinc sulphates, the carbon removing any residual organic matter from the solutions produced, which can be separated from the carbon, and crystallized. Alternatively, the acid can be filtered to obtain a decolourizing, finely divided carbon used as a substitute for carbon black or bone charcoal. Part of this may be used for purifying sulphate solutions made from the filtered acid.  The acid treated may be that used in the purification of petroleum and lubricating oils, or the acid obtained in the production of alcohols, ethers, and other organic compounds by hydrolysis of alkyl sulphates made by absorption of olefines in sulphuric acid.  According to examples: (1) Separated sludge acid of about 40--54 per cent H2SO4 is concentrated to 70 per cent or higher, and autoclaved for \ba1/4\be--2 hours at 175--180 DEG C., the pressure being sufficient to raise the boiling point to this temperature.  The gases may be vented continuously or intermittently. The product is neutralized with bauxite to give a basic solution of aluminium sulphate which is separated and worked up to give alum. (2) Sulphuric acid, obtained by hydrolysis of ethyl sulphates, of 70 per cent concentration, or concentrated to approximately this figure, is autoclaved as in (1).  The product may be used to produce alum, or may be filtered and the carbon washed with water and weak alkali, and dried at 80 DEG  C.  (3) Waste acid containing such a small proportion of soluble organic matter that the carbon obtained is insufficient for purifying the sulphate solutions may be mixed p with a more impure acid or separated tarry matter, and the mixture autoclaved as in (1).  The product is used for preparing sulphates.

Abstract: 551,465. Multi-ply paper bags &c. ROBINSON, F. G., and PAPER SACKS, Ltd. July 22, 1941, No. 9255. [Class 94 (ii)] In a block-bottom closure for a multi-ply paper bag or sack with stepped headings, as described in Specifications 343,447 and 443,950, the front heading of the tube is first folded into the plane of the sack, causing the corners to fold inwardly and form the triangular side flaps 5. The folded front is then refolded on itself at the line 3a upwardly and inwardly into the position shown at 6, while at the ends the headings are folded at right angles to the transverse folds of the tube along the line 6a and tucked under the inward sides of the lower corners of the flaps 5. The closure may be secured by adhesive applied to the headings before folding. In Fig. 4 the beginning of the final closing operation is shown. The back heading 6b is folded on the line 3b on to the front; and at its ends is folded on the crease 5b, so that this crease makes an angle of about 65 degrees with the folds of the closure that lie transversely of the sack. This angle enables the folded corner 5d to cover the underlying step of the front heading.
