Title: Linking device for use with weighing assembly - connecting grape crusher hopper with pump
IPC: F16L23/02
Filed: 1976-01-30
Abstract: Device for connecting a grape hopper crusher (I) with a pump (II) in a weighing assembly, fitted with an indicating dial, comprises a pliable sleeve made of rubber or a rubberised fabric; it has a smooth bore with a radial reinforcement of a coil of spring steel, which prevents it from being flattened by the suction of the pump.

Title: Copper recovery from iron contg sulphidic ore or concentrate - by oxidising weakly acidic extract to ppte ferric hydroxide and sulphur
IPC: C25C1/12
Filed: 1976-02-13
Abstract: Copper is extracted from ores or concentrates contg. Cu and Fe by dispersing the ore or concentrate (pref. a sulphidic ore, esp. chalcopyrite, malachite or azurite) in an electrolyte soln. contg. Cl- ions, heated to a temp. between 50 degrees C and the b. pt. of the soln.; and introducing finely disposed air or another O2-contg. gas into the suspension whilst maintaining the pH at 1.5-7.0, whereby iron is pptd. as Fe(OH)3 whereas copper remains in the soln. as Cu2+ ions. In the case, when a sulphidic ore or concentrate is used, elemental sulphur is pptd. The pH is maintained with in the above range by addition of HCl or by anodic oxidation of water. Copper is subsequently recovered from the soln by chemical displacement with iron or by electrolytic deposition. The one-stage process is less expensive than the conventional multistage process. There is no pollution of the surrounding atmos. The process is carried out at atmospheric press. (Fe(OH)3 and elemental sulphur are valuable by-products.

Title: Pressure dependent flow limiting valve - has sliding plug which shuts off flow completely at preset max. rate
IPC: F16K17/24
Filed: 1976-05-10
Abstract: The flow limiting valve has a cylindrical body (1) with screwed end caps. An inner sleeve (4) is clamped between the end caps (2, 3) and sealed with O-rings (6). The sleeve (4) is provided with four holes (10, 11) at each end. A plug (5) is free to slide within the inner cylinder and its travel is limited by the abutments (2b, 3b) of the end caps. As fluid flows through the inlet (9) it maintains the plug (5) in a position between the two sets of holes. When the flow exceeds the pre-set value the pressure difference across the plug increases so that it is pushed upwards and blocks the outlet (13) and shuts off the flow completely.

Title: Aqueous resin dispersion for electrodeposition - by copolymerisation of a diene, partly neutralised unsatd. acid and drying oil
IPC: C08F236/04
Filed: 1976-07-23
Abstract: Aqs. dispersions for electrodeposition of resins on an electrically conducting substrate are prepd. by polymsn. of a mixt. of (A) a diene and (B) an at least partly neutralised reaction prod. from (1) an unsatd. carboxylic acid or anhydride and (2) a drying oil or polybutadiene. The copolymer is prepd. in aqs. medium in the presence of an oil-sol. free radical catalyst. It is used for surface coating of metals, or other materials e.g. glass or plastics to which an electrically conducting coating has previously been applied. Previous electrodeposited coatings, e.g. those of US 3511816 had poor adhesion, were not uniformly deposited and were not very corrosion resistant. Those of the invention have an unexpectedly good bath stability, combined with good adhesion and good corrosion resistance. H2O is the only solvent and wt. loss on curing is 5%. In an example 71.3 pts. wt. of an epoxy fatty acid ester (prepd. from Epon 828, Shell Chem. Co. and Pamolyn 200 fatty acid mixt. ex Hercules Inc.), 110.2 pts. wt. de-ionised H2O, 25.7 pts. wt. styrene, catalysts and stabiliser etc. were reacted with 60 pts. wt. 1,3-butadiene for 10 h. at 73 degrees C and 2.1 kg/cm2 press. The prod. diluted to 20% solids was applied to steel sheets for 4 mins. at 400 V and gave a smooth 25.4 mu thick coating.
