Title: Making a Fibre-Reinforced Metal Matrix
Inventor: BAKER ALAN ANTHONY
IPC: C25D1/00
Filed: 1968-07-15
Abstract: 1,177,301. Fibre reinforced article. ROLLSROYCE Ltd. 15 July, 1968, No. 33681/68. Addition to 1,139,817. Heading B8G. [Also in Division C7] A fibre reinforced metal matrix is made by winding at least one continuous fibre, e.g. of C or B on to a former and simultaneously coating the or each fibre with metal or alloy, e.g. by electrodeposition, electroless plating or vapour deposition, and pressing the or each fibre against the former by locating at least one pressure member, e.g. a roller or an endlessdriven belt, adjacent the former. As shown, a fibre 15 (or tow or yarn of fibre) from a reel 16 is passed to a bridge 12, mounted on a guide frame 13 above a plating tank 11, over a pulley 21 on a carrier 22 reciprocating on rails 23, 27 to be wound on a former 34 rotating in bearings 35, 36 in the bridge and immersed in the electrolytic bath. The roller 50 may be made of porous material and electrolyte may be fed via a pipe 51 to the interior of the roller, in which one of the electrodes 52 is mounted, to wet the fibre as it is being pressed against the former. During electrodeposition, the current may be reversed in polarity. The motor 38, which rotates the former via gears 37, 39-41, and the motor 29, which reciprocates the carrier via worm-shaft 30, may be synchronized to ensure winding on the former at a predetermined rate. When using a tow of fibres for making the matrix, the fibres may be spread by passing the tow over a convex surface prior to winding.

Title: A method of manufacturing a microwire
Inventor: ZABOROVSKY VITALY IPPOLITOVICH
IPC: B22D11/00
Filed: 1965-08-13
Abstract: Micro-wire is made by forming the end of a glass tube to the shape of a drop formed by a measured quantity of the molten metal alloy, fusing the measured quantity in the cavity and drawing out a capillary containing the micro-wire from the molten end of the glass. The glass and metal, a Cu-Mn-Ni alloy as disclosed, are degreased before use and the metal subjected to vacuum.  The heating is effected by a high-frequency induction furnace, the cone angle of which may vary from 60 to 100 degrees.  The linear resistance of the micro-wire may be varied by varying the viscosity of the glass used. The time of fusing of the metal drop is controlled. The process may be made continuous.  Three grades of glass are given, all falling within the following ranges: SiO2, 71-76; B2O3, 15-19; PbO, 4.4-5.6; Na2O, 1.8-3.3; K2O, 1.2-2.3; Al2O3 up to 2; Fe2O3 up to 2; CaO up to 1.

A method of bonding metals by means of adhesives which are hardened by polymerization, using hardeners and polymerization accelerators is characterized in that the hardener is distributed as finely as possible over the metal surfaces to be bonded and the adhesive, containing the accelerator, is spread over the surfaces and the bonding is carried out in known manner. A peroxidic compound is used as a hardener and an N-dialkylolamine containing a tertiary aromatic amine the boiling point of which is higher than 230‹ C. is used as an accelerator. The hardener or the accelerator is applied to the metal surfaces in the form of a solution containing a soluble polymer and small quantities of an adhesive. The metal surfaces are pickled or mechanically pretreated e.g. sand blasted before applying the accelerator or hardener by spraying, brushing, dipping or atomising. The treated metal may be stored for long periods and then jointed by applying a binder containing the accelerator or hardener in known manner. A mixture consisting of unsaturated polyesters, acrylic or methacrylic esters and polyvinyl esters or a mixture of monomeric, polymerizable compounds, polymers of such compounds and polymers which contain the grouping (CH 2 -CCl = CHCH 2 -) n  is used as a binder to which is added either the hardener or the accelerator.
