Title: Electrocoating metal parts having a substantially circular
IPC: C25D13/14
Filed: 1971-10-28
Abstract: 1361657 Coating can tops AMERICAN CAN CO 28 Oct 1971 [29 March 1971] 50236/71 Heading C7B A method of coating round metal parts having uncoated edges, e.g. can tops, with a resinous organic material comprises rolling the parts between aligned grooves of an electrode guide member situated above a bath containing the resin and of a non-conducting guide member immersed in the bath. The parts are partially immersed in the bath for a time sufficient to permit rotation of the uncoated surface through the bath. For a complete coating the depth of immersion should be at least half the diameter of the part. The electrode guide member may be a rail and the non-conducting guide a moving endless belt. Alternatively the electrode guide member may be a rotating wheel and the non- conducting guide may be a fixed arc-shaped outer rail. The groove in the electrode guide may contain rubber tubing to increase the grip. The method may be used to repair an existing resin coating on a can top. In Figs. 1 and 2 can tops are passed down chute 33 on to endless belt 47 driven by wheels 51, 53, 55, 57 and 59. The tops 21 are received in groove 41 of rail 43 and groove 45 of endless belt 47. A rolling, wiping electrical contact is maintained between the can top and the rail whilst deposition takes place. The coated tops are passed out on to belts 65 and the resin is baked. The can tops may be aluminium, aluminium alloy, tin plate, tin free steel or black plate. The electrolyte may be 2 per cent acrylic resin in purified water.

Abstract: 1363767 Automatic speed control ROBERT BOSCH GmbH 12 Nov 1971 [13 Nov 1970] 52558/71 Heading G3R Pulses are produced in synchronism with the rotation of the crank-shaft of an internal combustion engine and form the input to a speed regulating circuit which controls the energization of a rotary armature electromagnetic device connected to the engine throttle valve. As shown, a winding 49 associated with the engine ignition generator supplies power lines 55, 56 over rectifiers 51, 52. The power is regulated and smoothed by Zener diode 53 and capacitor 54. The winding 49 also supplies pulses to a differentiating pulse shaper 60 and thence to a monostable multi-vibrator 70 producing square pulses of a predetermined length at the input frequency. A filter 80 time-averages the pulses to produce a frequency-proportional direct voltage which is compared with a reference voltage fixed by resistors 94, 95. Adjustment to a desired level is achieved by setting a potentiometer 97 in regulator circuit 90. An operational amplifier 91 with a P I characteristic controls transistors 101, 102 to adjust the current in a coil 34 which forms part of a rotary armature device, Figs.2-5 (not shown). The armature has a varying airgap and its rotary position determines the setting of the throttle valve of the engine. The load driven by the engine may be an A.C. or D.C. generator, a water pump, a power saw, or a rotary hoe. With a generator as load, a faster response to load changes may be achieved by applying a differentiated current signal to terminal 98 of regulator 90 using a current transformer, Fig. 7 (not shown).

Abstract: 1,254,967. Separating straight chain hydrocarbons. TEXACO DEVELOPMENT CORP. 28 Oct., 1969 [31 Oct., 1968], No. 52642/69. Heading B1L. [Also in Division C5] Straight chain hydrocarbons are separated from a mixture of straight and non-straight chain hydrocarbons using a molecular sieve adsorbent, such as a sodium calcium aluminosilicate of pore size 5, by using as purge gas and as desorption gas a mixture consisting of a major amount by volume of at least one straight chain hydrocarbon having an average of 1-3 carbon atoms less than that of the lightest straight chain hydrocarbon component of the feed and a minor amount of at least one straight chain hydrocarbon having an average of 5-7 carbon atoms less than that of the lightest straight chain hydrocarbon component of the feed. A vapourised feed from line 12, e.g. a heavy kerosine or gas oil boiling from 325- 670F and containing a mixture of C 10-20  hydrocarbons, is passed through the adsorber 14 at 575-675F and 10-50 p.s.i.g. and a stream 16 containing a reduced amount of straight chain hydrocarbons is recovered together with desorbing gas from a previous desorption step. The stream 16 is fractionated at 18 to provide a recycle stream of desorption gas 19 and a stream 21. The feed from line 12 is discontinued and the vessel (now shown as 14A) is depressurised to 0-10 p.s.i.g. by venting through lines 26, 27 and 28 and the accumulator 54 and purged with desorption gas from line 44 which is the accumulated at 54. The vessel (now shown as 14B) is repressurised to the desorption pressure of 11-75 p.s.i.g., which is suitably 1-25p.s.i.g. above the adsorption pressure, and desorption gas is passed through the vessel, countercurrent to the feed during the adsorption. The desorption effluent is removed along line 39 and fractionated at 60 to provide a stream of straight chain hydrocarbons and a stream 62 of recycle desorption gas. The vessel is then depressurised to the adsorption pressure and recharged with a mixture purge recycle from the accumulator 54 and fresh feed from line 10. The olefin S, N and aromatic contents of the feed can be reduced by catalytic hydrogenation. More than one vessel 14 can be used in the process cycle. In examples the use of mixtures of n-undecane and n-heptane as the purge and desorption gas is compared with the use of 100% n-undecane.

Abstract: Metal articles, in particular metal pipes, metal containers and large metal parts, preferably large pipes, are coated with cured epoxy resin compositions, the coating comprising a cured coating containing A) a solid epoxy resin based on 4,4'-diphenylolpropane and/or 4,4'-diphenylolmethane and epichlorohydrin, B) a curing catalyst and C) thixotropic agents, where the curing catalyst B) contains at least one compound B1) of the formula (I) or (II) <IMAGE> in which R is hydrogen, or B2) an adduct of the compounds B1) or substituted compounds of these formulae in which R is as defined in Claim 1 with low-molecular-weight epoxy resins having an epoxide equivalent weight of from 50 to 2000, or B3) a mixture of component B1) or B2) with the abovementioned substituted compounds of the formulae (I) and (II). The metal articles are coated with a pulverulent paint based on highly reactive curable epoxy resins which gives, in particular, toxicologically acceptable, heat- and chemicals-resistant, electroinsulating coatings. During this operation, the articles are heated to a temperature above the melting point of the resins, but sufficient for curing the epoxy resins, the resins are applied to the hot surface, which has already been cleaned before the heating, in the form of pulverulent paints by the electrostatic spray process or the whirl sintering (fluidised-bed sintering) process, melted to form a uniform film and cured directly without a further operation. During the application and curing process of the film, cracking phenomena of the organic components of the paint are not observed, in spite of the high temperature of the substrate, so that neither discolouration of the coating nor impairment of the properties occurs. The coatings are distinguished by the absence of pores and the high impact strength and by resistance to water and aggressive liquids.

The piston is subjected to braking to produce an aperiodic movement of the pointer having a semi period similar to human tissue. The disc 31 is rotated relative to a mark 32a on the casing, or pointer relative to a scale on the casing, to indicate, by means of the radial lines, the time of the dwell period and the depth at which the diver is to effect the dwell stop. The piston 36 is provided, as braking means, with a bush 38 the diameter of a bore 39 and the length of which is such that the return of the piston 36 to the intial position enables the instrument to imitate the type of human tissue for which the instrument is to be used. The piston may be replaced by one or a plurality of blades on a rotor. In an alternative embodiment, a battery of four instruments in a case are provided, each having different bushes 38 to indicate the duration and depth of the decompression stops applicable to four different types of human tissue.
