Title: Improvements in and connected with wire twisting machines, particularly adapted for the production of snares
IPC: D07B3/12
Filed: 1921-11-29
Abstract: 188,969. Barnes, A. Nov. 29, 1921. Making wire articles; twisting wires together.-In a machine for twisting wires together, particularly for making rabbit and like snares, the wire strands are mechanically twisted at one end and held at the other end on an anchor pin, which is carried by a flexible support which flexes during twistmg. The wire h is passed from a drum k contained in a tray j. through an eye in a pillar g, and is first wound round an eyelet l, which is then placed round a twisting hook d carried bv a mechanically-rotated spindle, the wire being then passed round the reduced end of an anchor pin f secured to a blade spring e, and after the desired number of strands is obtained is then secured. The twisting operation causes flexing of the spring, which may engage a stop to enable the operator to observe when sufficient twisting 'has been accomplished. The apparatus may be provided with means to eject the article automatically when twisting is completed. For this purpose a blade spring m which passes over the anchor pin is normally retained in depressed position by a pivoted spring catch r, which is pulled back at the completion of the operation by a spring-retracted lever t, which is provided with a lateral projection engaged by the spring e to tilt it forward when the twisting operation is completed. The spring m, when released, forces up a cross bar connected to a pair of spring-retracted rods o so as to push the article off the anchor pin. If automatic ejection is not required, a cross bar operated by hand may be used. The lever t may be adjustable or an adjustable device may be placed between the levers t, r ta vary the amount of the twist.

Abstract: 859,725. Electro-depositing iron nickel alloy films. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Oct. 2, 1959 [Oct. 9, 1958], No. 32334/58. Class 41 An approximately 80/20 nickel-iron thin film having a substantially rectangular hysteresis loop is deposited on a metal former in an aligning magnetic field by making the former the cathode in an electrolytic cell containing a solution of nickel and ferrous sulphamates, the concentration of nickel ions being greater than 100 gm/litre, the ratio of nickel ions to ferrous ions being between 35 : 1 and 40 : 1, the pH being between 2 and 3À5, the temperature below 30‹C., the current such that the deposition potential lies above 890 mV, and the solution concentration being maintained substantially constant on the surface of the cathode. The electrolyte may include boric acid, sodium saccharin, or sodium naphthalene tin sulphanate. The magnetic field may be produced by passing A.C. or D.C. through a coil surrounding the cell, or axially through the cathode, or both. The depositing current may initially be high enough to deposit a thin layer of pure nickel; it is then reduced to deposit the alloy. The cathode may be rotated and a stream of gas bubbles, e.g. N, may be released underneath it to ensure constant concentration of electrolyte over the cathode. The metal cathode former may be Cu, Ni, Be-Cu, Mo, Cr, Pd, Ag, or brass and is preferably preetched with acid, electro-polished, and polyethylene film mask applied to restrict the area to be plated. A flash coating of Ni may be applied before the deposition of Ni/Fe.
