Title: Improvements relating to road surfaces
IPC: E01C7/35
Filed: 1937-07-15
Abstract: 499,143. Roads. TARMAC, Ltd., and PORTER, H. July 15, 1937, No. 19592. [Class 107] A method of surfacing roads consists in causing fibrous pulp of a lighter colour than that of the original road surface to enter the surface voids and cavities of the road, and incorporating with the pulp, or coating the pulp with, a waterproofing or colour-protecting material either before or after application of the pulp to the road surface. The pulp may be prepared from waste paper which is disintegrated and digested in hot or boiling water, an alkali being used to assist in breaking down the paper structure. Sawdust may be used with the pulp, if desired, together with suitable colouring matter. The pulp is poured on to the road surface and forced into the surface voids by a squeegee ; the surface is then rolled with a rubber-tyred roller. The pulp may be treated either before or after application to the road surface with a resinous or linseed oil emulsion, which may contain rubber latex, or the road surface, after application of the pulp, may be dressed with an ordinary bituminous emulsion containing a high percentage of colour to mask the colour of the bitumen. The pulp may, alternatively, be mixed, prior to application, with either a rubber latex provided with an addition of starch to prevent coagulation of the latex, or a mixture of molten paraffin wax, warmed lime, and water. The pulp may be prepared from sugar-beet pulp or wood pulp, instead of from waste paper.

Title: Therapeutically useful solutions
IPC: C08G73/02
Filed: 1953-07-16
Abstract: Polyethyleneimine derivatives useful as blood-plasma extenders and for other medical purposes (see Group VI) are prepared by acylating a branched ethyleneimine polymer with a C1 to C4 alkyl carboxyl radical, which may contain a methoxy group, or by sulphalkylating the polymer with a C1 to C4 alkyl sultone.  The products may vary in molecular weight from 1000 to more than 50,000 depending on their intended use.  The products may also contain limited numbers of hydrophobic acyl radicals, e.g. stearyl, provided the molecule is otherwise sufficiently hydrophilic.  In examples a technical polyethyleneimine of molecular weight about 25,000 is reacted with (1) acetic anhydride; (2) acetic anhydride and subsequently with butane sultone; (3) acetic anhydride; (4) methoxy acetic acid anhydride; (5) butyric acid anhydride; (6) isobutyric acid anhydride. In Example 7 ethylene imine is polymerized at 80 DEG  C. with acetic anhydride as catalyst to a low polymer which is then acetylated.ALSO:A preparation useful as a blood plasma extender, for eliminating toxic substances from living organisms, or as a repository for the intravenous administration of drugs or other therapeutic agents, comprises a dilute aqueous solution in pyrogerm free water of a relatively non-toxic, hydrophilic branched macromolecular compound which is an ethylene-imine polymer acylated with a C1 to C4 alkyl carboxyl radical, i.e. a radical containing 1 to 4 carbon atoms in addition to the carbon atom of the carboxyl group and which may include a methoxy group, or sulphalkylated with a C 1to C4 alkyl sultone.  The polymer may also contain limited numbers of hydrophilic acryl e.g. stearyl, residues.  Macromolecular compounds are defined as those having molecular weights exceeding 1000.  Products useful as repository vehicles will have molecular weights exceeding 50,000 while products useful for the elimination of toxins should have molecular weights of 10,000-20,000.  Examples are given of the preparation of suitable acylated or sulphalkylated polymers (see Group IV(a)).

Title: A machine for rolling screw threads
IPC: B21H3/04
Filed: 1931-07-15
Abstract: 370,773. Rolling screw threads. BAUER & SCHAURTE RHEINISCHE SCHRAUBENUND MUTTERNFABRIK AKT.-GES., 24, Furtherstrasse, Neuss, Germany.-(Assignees of Reinhardt, B. ; 42, Bouchestrasse, Berlin.) July 15, 1931, No. 20340. Convention date, Aug. 30, 1930. [Class 83 (iv).] In a machine for rolling screw threads, the work piece S is rolled between two parallel rolls a, b having threads of the same pitch, and inclined at the same helical angle as the threads to be produced, the rolls being rotated in the same direction but at slightly different speeds, that of the roll b being the higher, so that during operation the work pieces are first engaged by the rolls at the section A, A, Fig. 2, and are then rotated through a number of revolutions while they are moved slowly through the roll pass. The rolls may be driven at the required speeds through gears Z, Za, Zb, and the width of the pass between the pitch surfaces of the rollers is equal to the diameter of the pitch cylinder of the work piece. In the central transverse plane, Fig. 1, the profile of the pass is exactly complementary to the profile to be produced on the work. The threads on the rolls are of opposite hand to those to be produced and since the pitch and helical angles on the rolls and work are equal, the lead of the threads on the rolls bears the same relation to the lead of the work thread as the pitch diameter of the rolls bears to the pitch diameter of the work piece, this ratio being a whole number. The work pieces are conveyed by suitable guides g and fed in the direction of the arrow f by a reciprocatory slide e. The rate of feed through the pass is determined by the difference between the circumferential speeds of the rolls which is such that the work piece makes several revolutions while travelling from the plane A, A to the middle of the pass, thus ensuring the gradual formation of the thread. The finished work pieces may be conducted away from the machine along guides h. In order to ensure that when the work piece is first acted on at the plane A, A the rolls are in correct crest-to-trough relationship the interval between the feeding of the work pieces must be regulated. Thus if N is the number of threads on the rollers then the correct meshing conditions will be repeated at intervals of <x>/n turns of the roll a and <y>/n turns of the roll b where x and y are integers and y is greater than x. The values of x and y are determined by the possible rate of feed through the machine. Thus the feed mechanism must be operated in definite timed relation with the speeds of the rolls a, b, and is therefore positively operated from the driving mechanism of the rolls. The invention is stated to be particularly advantageous for cold rolling.
