Patent GB-852994-A (GB)
Title: Apparatus for screening pulp
Inventor: BOWEN ROBERT E
IPC: D21D5/06
Filed: 1958-03-17
Abstract: 852,994. Filters ; centrifugal strainer separators. NORTH CAROLINA PULP CO. March 17, 1958, No. 8418/58. Class 46. Mixture (e.g. paper pulp) to be treated is introduced at 26, Fig. 2, and flows along a channel 28, Fig. 1, to an inlet 36 between fixed members 30 and 32. It is forced against a fixed cylindrical screen 16, Fig. 1, by the centrifugal action of blades 80, Fig. 4, on a rotating shaft 20, Fig. 1. Axial movement of pulp to the left is promoted by the pitch of the blades (which move upwards as viewed from the front, Fig. 4), but is prevented except in the vicinity of the screen by a disc-shaped baffle 62, 62<SP>1</SP>, extending from the shaft 20 to the blades. Pulp thus reaching the far side of the baffle is re-suspended in diluting-water admitted under low head at 38, Figs. 1 and 2, and flowing along a channel 44 to inlets 54 and 56 between fixed members 46, 48 and 50. The diluting-water washes further acceptable fibrous matter through the screen. The proportion of such matter thus washed through, and hence the richness of the finely-rejected residue, is controlled by a valve 37 on the water pipe 38. The residue is maintained in motion by extensions 90, Fig. 4, on two of the blades and is finally discharged at 60. Treated pulp is discharged at 58. The blades preferably slope backwards slightly in the direction of rotation, in consequence of which the blades tend first to lift the pulp radially towards the screen, and thereafter to cause suction, at any one place, (thus cleaning the screen), and, further, the velocity difference between blades and pulp is promoted.

Title: Improvements in weft-cutting mechanism for automatic looms
IPC: D03D49/70
Filed: 1954-03-29
Abstract: 754,668. Automatic cop changing in looms;  cutting weft. SAKAMOTO, K. March 29, 1954, No. 9182/54. Class 142 (2). When cop changing is initiated by a cop feeler and permitted to continue by a shuttle feeler, a slide 25 mounted on the breast beam is moved rearwards to bring cutting and clamping blades 31 into the path of the shuttle box; during this movement, a pin 36 on the movable blade is deflected by a cam 37 to open the blades; the pin then encounters a cam 38 which it rocks about a pivot 40 against the action of a torsion spring 41, the pin therefore riding past the cam without being affected thereby. When the slay beats up, it pushes the slide 25 forward by striking a screw 28, the pin 36 being operated by the cam 38 and riding past the cam 37, which is also spring loaded. The weft of the spent cop is thus cut near the eye of the shuttle, and the end extending to the selvedge is clamped until the blades are opened at the next replenishing operation. Reference has been directed by the Comptroller to Specification 708,743.

Title: Compositions for the reversal of inflamation in animals
IPC: A61K38/16
Filed: 1957-03-22
Abstract: A composition for the reversal of inflammation in animals comprises a mixture of streptokinase or streptokinase - streptodosnase and human plasminogen.  The streptokinase-streptokinase mixture which has been found to be of use in reversing inflammation in humans is non-effective in cases of inflammation in animals e.g. cows and horses, but the addition of a small amount of human plasminogen to the mixture or to streptotinase alone results in a composition that is effective in these cases.  The preferred concentrations of ingredients are 1 unit of human plasminogen to 1-500 units of streptokinase (each unit is defined), and the compositions may take the form of dry mixtures in which solutions of the ingredients have been mixed and freeze dried, or solutions of the ingredients in saline preferably buffered to pH 6.8-7.8.

Abstract: 292,298. Johnson, J. Y., (I. G. Farbenindustrie. Akt.-Ges.). April 8, 1927. Mineral waxes, purifying.-Montan wax is purified by hot concentrated acetic acid. The wax may have previously been deresinified, bleached, e.g. as in Specification 289,621 or German Specification 409,420, or otherwise treated. In an example crude montan wax is treated with glacial acetic acid in a Soxhlet apparatus; pigments and fatty acids are dissolved out. Or 500 grams of crude or deresinified wax are heated to boiling with 700 c.c. of concentrated sulphuric acid and 2000 c.c. of water, 700 grams of chromic acid as a concentrated aqueous solution are slowly added with stirring, the mixture poured into hot water, and filtered when cold. The bleached but strongly saponified wax is then boiled with 5 litres of glacial acetic acid, and carefully cooled to separate the wax as an upper layer. This layer is washed with water and melted in vacuo. The acetic acid solution is diluted or further cooled to separate montanic acid; this is filtered off, washed, and melted in vacuo.
