Abstract: 1365662 Electrodes for lead-acid batteries TYCO LABORATORIES Inc 9 Jan 1973 [7 Feb 1972] 1124/73 Heading H1B A bipolar electrode comprises, Fig. 1, a central base-plate 2, two grids 4, two frames 6 and a plurality of U-shaped lead strips 8, the base-plate, grids and frames being of an electrically-insulating plastics material. The preferred plastics material is a polycarbonate plastic which is thermoplastic. In one method of assembling the electrode the bent sections 34 of the strips 8 are painted with a solution of polycarbonate polymer and the strips are applied to the baseplate 2 so that the sections 34 are received in slots 12 formed in one side of an aperture 10 and the legs 26a, 26b extend on opposite sides of the base plate. The assembly of the base-plate 2, grids 4 and frames 6 is then hot pressed to bond the components together, the upper sections 24 of the frames 6 being thermo-formed into the aperture 10 to close it. Thus, the strips 8 extend in fluid-tight manner through the baseplate and are bonded to it and to the overlying portions of the grids and frames. Fig. 3 shows a section through the bonded assembly. The apertures 22 in the frames 6 define spaces for receiving the positive and negative active material in the form of lead paste. These apertures 22 are coated with methylene chloride to which is adhered fibrous flock 32 of chopped glass fibres or Dynel (Registered Trade Mark), the flock on each side of the electrode then being coated, respectively with positive and negative paste. Preferably, the paste contains glass or Dynel fibres. In a modification, the flock is replaced by preformed mats. In other modifications the strips 8 are of lead-antimony alloy, lead-calcium alloy or lead-calcium-tin alloy. The H 2 SO 4  electrolyte may contain a small proportion of H 3 PO 4 . Alternative plastics materials for the parts 2, 4, 6 are P.V.C. and polysulfone.

Patent GB-717600-A (GB)
Title: Process for the recovery of sodium from waste sulphite liquor
IPC: C01D5/14
Filed: 1952-01-15
Abstract: The waste liquor from a sodium sulphite process of preparing wood pulp is concentrated, burned and smelted, sodium is extracted, predominently as sodium sulphide, in aqueous solution, and then adsorbed from the solution with a weakly acidic ion exchange material in the hydrogen form, whereupon the exchange material is regenerated with a sulphurous acid solution to produce a solution of sodium bisulphite and sulphurous acid for reuse in the pulping process. Chloride ions which may be present in the wood as sodium chloride are thus eliminated from the cycle.  In carrying out the process wood chips are pulped with the recycled solution and fresh sulphurous acid, the processed pulp is removed and the liquors passed to evaporators.  Salt cake or sodium carbonate is added to compensate for loss of sodium, and the concentrated liquor passed to a furnace wherein a sodium sulphide smelt is formed under reducing conditions. The pH of the solution of the smelt passing to the ion exchange columns is preferably above 6, and that of the regenerating sulphurous acid solution is less than 4.  Hydrogen sulphide evolved during the adsorption process is burned with added sulphur to produce sulphur dioxide from which the regenerating sulphurous acid solution is obtained.  If desired, sodium losses can be replaced by adsorbing in the ion exchange column sodium from other solutions, e.g. from the waste liquors used in the purification of unbleached pulps. Specification 469,051, [Group IV], is referred to.  Reference has been directed by the Comptroller to Specification 684,224.

Title: The manufacture of unsymmetrically acylated amino derivatives of arylarseno compounds
IPC: C07F9/74
Filed: 1926-01-19
Abstract: 269,647. Newbery, G., and May & Baker, Ltd. Jan. 19, 1026. Unsymmetrical acylamino-arylarseno compounds are prepared by intramolecular rearrangement of two symmetrical arylarseno compounds, one containing unsubstituted amino groups and the other containing acylamino gmups, by bringing them together in equimolecular proportions in a common solvent. The solvent may be a basic or acidic medium and may be associated with an organic solvent such as methyl or ethyl alcohol; the product is precipitated by adding a non-solvent, such as ether, or a reagent which forms an insoluble derivative or salt, such as an acid or alkali. The acylamino starting material maybe first prepared by reduction of an acylamino-nitroarylarsenious oxide or arsinic acid. Examples are given of the preparation of (1) 5-acetylamino- 3 : 3<1> - diamino-4 : 4<1> - dioxyarsenobenzene from 3: 3<1>- diamino -4 : 4<1> - dioxyarsenobenzene and 3:3<1>- diamino-5: 5<1>-diacetylamino- : 4<1> - dioxyarsenobenzene (obtained by nitration of 3- acetylamino-4-oxyphenylarsinic acid and reduction of the resulting 5-nitro-compound); the product is the same as that prepared by reducing a mixture of 3-amino-4-hydroxy-phenylarsinic acid and 3-amino-4-hydroxy-5-acetylamino - phenylarsinic acid; (2) 3-acebylamino-3<1>-amino-4 : 4'- dioxyarsenobenzene from 3: 3<1>-diamino-4 : 4<1>- dioxyarsenobenzene and 3: 3<1>-diacetylamino- 4 : 4<1>-dioxyarsenobenzene; (3) 3<1>-amino-3 : 5<1>- diacetylamino-4 : 4<1> - dioxyarsenobenzene from 3 : 3<1> - diacetvlamino - 4 : 4<1>-dioxyarsenobenzene and 3 : 3<1> - diamino-4 : 4<1> - dioxy-5 : 5<1>-diacetylaminoarsenobenzene (obtained by reduction of 3-nitro or -amino-4-oxy-5-acetylaminophenylarsinic acid); the product is identical with that obtained by reduction of 3-acetylamino-4-oxyphenylarsinic acid and 3-amino-4-oxy-5-acetylaminophenylarsinic acid; (4) 3-amino-4: 4'- dioxy-3' :-5<1> - diacetylaminoarsenobenzene from 3 : 3<1> - diamino - 4 : 4<1> - dioxyarsenobenzene and 3 : 3<1>-5 : 5<1> - tetracetylamino-4 : 4<1> - dioxyarsenobenzene (obtained by reducing 3 :5-diacetylamino- 4-oxyphenylarsinic acid); the product is the same as that obtained by reducing a mixture of 3- amino-4-oxyphenylarsinic acid and 3: 5-diacetylamino-4-oxyphenylarsinic acid.

Abstract: 1,157,412. Sawing. OMARK INDUSTRIES Inc. 11 Jan., 1968 [17 Jan., 1967], No. 1585/68. Heading B5L. [Also in Division A1] A tree harvester comprises a harvester vehicle T, an articulated power-actuated boom B1, B having one end rotatably mounted on the vehicle, a mast 12 movably supported on the other end of the boom for positioning adjacent and in alignment with a tree, the mast including a power-operated tree holder and delimber 32a, 32b, and 34a, 34b, having a pair of knifeedged gripping jaws, at each end of the mast, a power-operated chain saw 36 resiliently supported on the mast for cutting the trees, and a power-operated tree mover 30, including a pair of convex jaws which grip the trunk of a tree for moving the tree endwise through the holders and delimbers. The mast is movable relative to the boom for swinging a tree, after it has been cut off to a generally horizontal position while the tree is held by the jaws of the holders. When the tree is in the horizontal position, a piston and cylinder (68), Fig. 10 (not shown), causes the tree to be grasped by the jaws of the tree mover 30 to move the tree to the right. As the tree moves through the holders and delimbers, the knife-edges of the gripping jaws strip the limbs and branches from the tree, and the tree is advanced in this direction for the full stroke of the piston (69), the length of which corresponds to the length of the sections into which the tree is to be cut, so that at the end of the stroke the saw 36 severs off a section of the delimbed tree. The piston then operates in reverse and causes the jaws of the tree mover 30 to release their grip from the tree so that the tree mover may move to the left, Fig. 10 (not shown), a distance equal to the stroke of the piston. When the piston again moves to the right, the tree is grasped by the jaws of the tree mover and the tree is again pulled through the delimbers and cut by the saw 36 at the end of the piston stroke. This succession of operations is repeated until the entire usuable portion of the tree has been delimbed and cut into sections.
