Patent GB-444626-A (GB)
Title: Improvements in and relating to methods of producing artificial cellulosic products containing nitrogen
IPC: C08L1/00
Filed: 1934-08-20
Abstract: Nitrogenous products obtained from hair, wool, horn, and the like by extraction with a non-aqueous solution of an alkali are added to cellulose solutions for the production of filaments, films, and the like.  In the case of viscose solutions, the sulphidation may take place either before or after the addition of the albumen product.  By the addition of acid a cellulose product containing nitrogen is precipitated, and this precipitate may be redissolved in soda-lye and worked up into filaments or films. In an example, wool is impregnated with a 10 per cent methyl alcoholic soda-lye, pressed down and heated to 60 DEG  C.  After removal of the alcohol the product is added to viscose which is worked up to filaments or films having a 3 per cent nitrogen content and an affinity for acid dyes.  In a second example, the cellulose and albumen derivatives are sulphidized together, and the solution worked up as previously.  In a third example viscose is poured into aqueous-alcoholic acetic acid and the mass pressed and placed in a solution of dichloracetic acid.  The product is placed in a soda lye which contains in solution the albumen derivative and after 24 hours the mass is worked up into filaments or films.  The mass may be further converted by treatment first with a solution of dichloracetic acid and then with the albumen solution.

Title: Surfacing materials for roads and the like
IPC: E01C11/00
Filed: 1963-06-17
Abstract: Road surfaces are made by a process in which a monomeric, polymerizable liquid is mixed with an aggregate and a particulate solid polymer which is swellable or soluble in the monomeric liquid, the composition is spread upon the sub-surface before the polymer particles are swelled through by the liquid, thereafter the composition is hardened by a polymerization accelerator.  In one embodiment a composition of aggregate, filler, polymethyl methacrylate and the oxidizing part of a redox catalyst is mixed with methyl methacrylate and glycol dimethacrylate containing chlorinated naphthalene, trichloroethyl phosphate and dimethyl-p-toluidine as the reducing part of the catalyst, spread upon a road sub-surface and left to harden at ambient temperature. In a modification the monomeric composition is sprayed on to a road surface, the aggregate/polymer composition is applied, further monomer is sprayed on and the whole mass is topped with a layer of aggregate.  The polymer/aggregate composition may also be mixed with the monomer in a bag and applied to the surface through a slit. The filler which may be present in the aggregate may be kaolin, chalk or quartz which may be surface-treated with zinc stearate.  Additional polar monomers may also be present.

In ultrasonic sounding apparatus (particularly for fish detection) the direction of the beam axis of the transducer 2, Fig. 1 (used for both transmission and reception) is varied in bearing and in inclination by respective motors 4, 5, echoes received by receiver 3 in response to transmitted pulses from generator 1 being fed via a control device 10 to a recording stylus 21 which moves across a (moving) record medium 20 (Fig. 2) on which it records information concerning the angles of inclination and of bearing of the transducer (traces s and g respectively), together with echoes received from fish and from the sea-bottom (traces b and f respectively), the arrangement being characterized in that the speed with which the stylus (driven by motor 8) traverses medium 20 is controlled via a device (e.g. a potentiometer) 6 driven by the " inclination " motor 5 to vary proportionally to the cosine of the angle of inclination, or to this angle less an angle dependent on the divergency of the transducer beam. By this means the true depths of objects giving rise to echoes are recorded such depths being independent of the inclination of the beam to the vertical. The " inclination " trace s is produced by an electric discharge between stylus 21 and a metallized layer on the lower side of the record medium 20 at instants determined by the electrical bridging of a pair of contact elements (rotated by the " inclination " motor 5) by a conducting element rotated by the stylus motor 8 (Fig. 3, not shown), a similar arrangement being employed for the production of the bearing trace g. Instead of a single stylus 21 a plurality of styli carried by a moving support such that as one stylus completes its traversal of the recording medium a second stylus reaches the position from which traversal commences may be employed. The device 6 (Fig. 1) may additionally control the stylus motor 8 to compensate for rolling of the vessel on which the equipment is mounted. A computer comprising e.g. rotary potentiometers may be. employed for deriving the cartesian co-ordinates of the echoes for direct display.
