Title: Method and apparatus for manufacturing resistors
IPC: H01C17/22
Filed: 1962-10-18
Abstract: 955,930. Wire wound resistors. NORTHERN ELECTRIC CO. Ltd. Oct. 18, 1962 [Feb. 12, 1962], No. 39525/62. Heading H1S. A wire wound resistor is made by winding on a cylindrical former of insulating material insulated wire in a length in excess of that required to establish the desired resistance, attaching one end of the wire to one of the terminals, continuously stripping the insulation from the other end of the wire while continuously measuring the resistance of the wound wire up to the point at which the wire insulation has been removed, terminating the insulation stripping when the resistance attains the required value, and attaching the stripped wire to the second terminal. Fig. 2 shows the preferred embodiment of apparatus for performing the invention in which the resistor is held between chucks 18 and 19, the terminal leads being accommodated in slots 20 and 21. One end of the winding is stripped of insulation and attached to terminal portion 12 Of the former, e.g. by welding with electrodes 38 and 39, thus connecting one end of the resistor to terminal 35b of the Wheatstone bridge network 32. The other end of the resistance winding is passed through loop 28 of the heating wire 27 and over contact member 30, the heating wire stripping the insulation off the resistance wire 16 thus allowing the contact member to complete the circuit connecting the resistance winding in the bridge network 32. The wire is thus pulled through the stripping device until the bridge indicates the desired resistance when the stripping is stopped and the stripped portion welded to terminal 11 by the electrodes 38 and 39.

Title: Method of improving the colloidal properties of a high solids synthetic rubber latex
IPC: C08F36/04
Filed: 1960-11-28
Abstract: A rubbery polymeric latex having large size latex particles is prepared by a process in which a conjugated diene is polymerized while dispersed in an aqueous emulsion containing 50 to 150 parts water per 100 diene, a micelle producing surfactant and a free radical initiator, at 40 to 85 DEG F. and forming a rubbery latex particle in which the monomer is soluble and is characterized by dispersing the monomer and sufficient surfactant in the water to form micelles to promote the conversion of monomer to polymer at an average rate of at least about 2% per hour during at least up to 40% conversion of monomer to polymer and stabilize the resulting latex particles during this conversion period but insufficient to prevent the surface tension of the system from increasing to a maximum value during polymerization and then decreasing to a minimum value (during agglomeration) when at least 40% of monomer has been converted to polymer, polymerizing the monomer with increase in the surface tension of the system, and treating the latex particles with agitation to cause agglomeration of the latex particles and a decrease of the surface tension when at least 40% of the monomer has been converted to polymer, removing unreacted monomer from the agglomerated latex and recovering the latex. Specified rubbers are butadiene, isoprene, chloroprene, 2-3-dimethyl butadiene, 2-ethyl-butadiene, 1-4-dimethylbutadiene, hexadiene-2-4, pentadiene, methyl pentadiene and piperylene polymers or copolymers with acrylic nitriles, styrene vinyl toluene, vinyl naphthalene, parachloro-styrene, methyl acrylate and methacrylate, acrylamide, methyl iso-propenyl ketone, methyl vinyl ketone, vinylidene chloride, isobutylene, and methylvinyl ether. The usual peroxy type initiators are specified as well as diazamino benzene, dipotassium diazomethane disulphonate, and triphenyl methyl-azomethane; Redox heavy metal compounds may also be present. Surfactants specified are fatty acid soaps, tall oil soaps, alkali methyl sulphates and sulphonates, cetyl trimethyl ammonium sulphate and the hydrochloride of diethyloleyl amide. The process may be carried out continuously.

Title: A method of treating liquids
IPC: B01J47/10
Filed: 1963-10-16
Abstract: In operation of a contacting vessel, the valve 7 is closed and the inlet valve 11 is opened and discrete particles of a treating material 12 are introduced under pressure through the inlet pipe 9 until the tank is filled with compacted material to the level of the retaining screen 8. In the tank shown, Fig. 1, the portion of the bed located above the distributer 2 will tend to become more compacted than the portion disposed below, but in Fig. 3, the entire bed will become compacted substantially uniformly throughout.  The valve 11 is now closed and an untreated liquid is fed under a predetermined pressure and in a predetermined volume into the bed.  As the content of the liquid in the tank increases, it will pass through the bed and exit <PICT:1012507/C1/1> tends to become spent or exhausted with the material near the bottom of the column showing the greatest degree of exhaustion. To replenish the material, outlet valve 7 of Fig. 1 or outlet valve 18 of Fig. 3 and inlet valve 11 are opened simultaneously and fresh material is introduced under pressure through the inlet pipe 9 so as to simultaneously force the most exhausted material out through resin outlet pipe and to retain the compacted bed.  In order to maintain the flow of effluent from the outlet pipe at a volume equal to that flowing therethrough during the normal treating operation, the control valve 5 is opened to a wider position than normal, thereby increasing the flow of liquid entering the bed. After a sufficient amount of new resin has been in the form of a purified effluent through the retaining screen 8, into the collecting chamber 13 and through the product outlet pipe 14.  After a sufficient period of time, the bed 12 <PICT:1012507/C1/2> introduced, both the inlet and outlet valves are closed and control valve 5 is returned to its original position.  Suitable means may be provided for automatically opening and closing the various valves at the proper time and for varying the opening of the control valve 5. Specification 1,012,506 is referred to.
