Title: Ferrule construction and a method of producing same
IPC: H01R11/12
Filed: 1965-05-14
Abstract: 1,048,203. Making electrical connections. INTERNATIONAL STANDARD ELECTRIC CORPORATION. May 14, 1965 [May 18, 1964], No. 20423/65. Heading B3A. [Also in Division H2] A method of making a ferrule for an electrical connector comprises the steps of rolling a sheet of metal into a tube having overlapping edges which are then secured together. As shown, the overlapping portion is first thinned by coining or stamping so that the inner and outer diameters form true circles and the edges are secured together by spot welds 24. A cut-out portion 28 forms an inspection hole and the ferrule is secured to a wire by soldering or crimping. In another embodiment, Figs. 7 and 9 (not shown), a ferrule has a tongue 23 to act as a contact retention clip. In another embodiment, Fig. 6 (not shown), the overlapping edges are joined by a seam weld. In another embodiment, Fig. 13 (not shown), the overlapping edges are joined by the crimping 27 which serves to retain the ferrule to the wire. In another embodiment, Fig. 11 (not shown), the ferrule is attached to a contact pin.

Title: Fuel mixture regulators for internal combustion engines
IPC: F02M21/00
Filed: 1920-07-10
Abstract: 148,850. Edison, T. A. March 4, 1919, [Convention date]. Fluid-actuated valves.-In an extension 5 to the normal air intake pipe 4 of a carburettor is mounted a plate 28 formed in one with a cam 26 pivoted to a valve 15. The air current deflects the plate and causes the cam to ride on the top of the pipe 9, and to lift the valve, thereby admitting air to the induction pipe 2 on the engine side of the carburettor. The vacuum in the induction pipe acts on the valve and opposes the force of the air current. The air port 21 for the valve 15 is adjustable by a split ring 23. When the engine stops, the plate 28 is vertical and the valve 15 is .on its seat.

The output of a rectifier at terminals 10, 10, is regulated by saturable reactors 6 in series with each rectifying element 3 and connected together at 8 to the input terminal of a filter circuit 7 which may be a capacitor, the junctions 12 of the saturable reactors and rectifiers being clamped to a regulating voltage during the non-conducting half cycle. As shown, this is effected by a D.C. source 13 and diode 9. Fig. 3 shows the voltage variations of the points 11 (E1), 12 (E3) and 8 (E 2 ), the latter voltage being constant when the filter 7 is a capacitor. E 3  follows E 1  until time t 2  when the reactor 6 becomes saturated. From t 2  to t 3  a current I 1  flows. From t 3  to t 4  E 3  follows E 1  and is then held at the clamping voltage E, of the source 13 until t 5  when it starts to follow E 1  again. The shaded areas represent the periods of positive and negative saturation of the reactor 6, and by varying the voltage E 2  the periods of conduction t 2  to t 3  may be varied. Other embodiments disclose (a) a filter circuit comprising capacitor and inductor, (b) the use of valves and transistors to determine the voltage E 4 , and the application to rectifier circuits of the polyphase bridge, single phase bridge, and biphase types.

Title: Improvements in and relating to methods of purifying halogenated aromatic hydrocarbons
IPC: C07C17/38
Filed: 1937-07-29
Abstract: Liquid or liquefied halogenated aromatic hydrocarbons, e.g chlorinated benzene, diphenyl and naphthalene, containing finely-divided carbon, produced, e.g. by passage of an electric arc, are purified by dispersing throughout the halogenated hydrocarbon an aqueous solution of a salt producing polyvalent ions which thereby extracts the carbon and is then separated. Sulphates of copper, aluminium, iron and zinc are salts specified. Dilute solutions containing, e.g. 3 per cent by weight, may be added in proportions of 20 parts by weight to 80 parts of halogenated hydrocarbon at about 50-80 DEG  C. and dispersed by agitation.  On standing, the aqueous solution rises to the top carrying the carbon.  The purified compounds is run off and entrained droplets removed, e.g. in a filter press or centrifuge. The salt solution may be precipitated by addition of a base such as sodium, potassium or ammonium hydroxide. Thus 10 parts of 3 per cent ferrous sulphate solution are mixed with 80 of the organic liquid, e.g. a 60 : 40 mixture of chlorinated diphenyl and chlorinated benzene, and 10 parts of 3 per cent caustic soda slowly added.  After removal of the precipitate, and standing, e.g. at 25 DEG  C., the water layer containing the carbon separates.ALSO:Liquid or liquefied halogenated aromatic hydrocarbons, e.g chlorinated benzene, diphenyl, and naphthalene, containing finely-divided carbon, produced, e.g. by passage of an electric arc, are purified by dispersing throughout the halogenated hydrocarbon an aqueous solution of a salt producing polyvalent ions which thereby extracts the carbon and is then separated.

Abstract: 584,064. Protective coatings. PYRENE CO., Ltd. (Parker Rust-Proof Co.). Oct. 30, 1944, No. 21184. [Class 82 (ii)] In a method of forming a phosphate coating on a metal surface, an aqueous accelerated solution of phosphoric acid or an acid phosphate is brushed over the surface by repeated contact of bristles with each part of the surface, each part being so brushed within the first one-tenth of the time in which a coating would be fully formed without brushing. As shown, cylindrical brushes 4, rotating so as to brush in the direction of motion of a strip 1, make contact with the strip immediately after the solution has been applied from spray pipes 5, a further spray being applied immediately after brushing. The bristles of the brushes, which may intermesh, should have a peripheral speed greater than the linear speed of the strip, and may make contact with the strip for one twentieth of the total coating time. The sheet and the coating solution should be brought into approximately the same temperature. Examples of phosphoric acid coating solutions are given, but the acid phosphates of zinc, manganese or iron may also be used.
