Title: Method and apparatus for the adjustment of milk to a desired flat content
IPC: A01J11/10
Filed: 1973-11-21
Abstract: 1435984 Fat content adjustment of milk DIESSEL GmbH 21 Nov 1973 [5 July 1973] 54043/73 Heading A2B The fat content of fresh milk is adjusted by the continuous addition thereto of an amount of skim milk dependent on the continuously measured fat content of the fresh milk, the controlled addition of skim milk being effected after the time required for the evaluation of the fat content. Fresh milk, in feed line 1 after sampling at 7 is passed via storage vessel 6 and mixed at 15 with skim milk delivered via feed line 2 through adjustable valve 9. The dwell time of the fresh milk between the sampling point 7 and the mixing point 15 corresponds to the time required for the sample to be analysed. The value of the fat content, determined at 8, is fed to computer 10 which together with measurements of fresh and skim milk flow rates determined at volumeters 4 and 5, actuates the adjusting valve 9 accordingly. The storage vessel can be varied in capacity in order to alter the dwell time of the fresh milk. Normally the dwell time is 20 secs.

Difficultly combustible foam plastics comprise 6-99% by wt. of hollow beads and 94-1% of an adhesive capable of bonding the beads, the hollow beads being formed by expanding a finely divided copolymer, formed by polymerizing a mixture of from 70-92 parts by wt. of vinyl chloride and 30-8 parts of ethylene and/or propylene, at an expansion temperature below the softening temperature of the copolymer and using a blowing agent which is either gaseous at the expansion temperature or which decomposes with evolution of a gas, the adhesive being added to the polymerization mixture before or after formation of the hollow beads. The blowing agent may be unpolymerized vinyl chloride, ethylene and/or propylene or propane or pentane. The adhesive may be methyl or carboxymethyl cellulose, starch, polyacrylic acid, gelatine, a melamine resin, waterglass solution, a urea-formaldehyde condensate, a dextrin, polychloroprene or an ethylene/vinyl chloride copolymer. In examples the monomers were polymerized under pressure in an aq. suspension containing optionally the adhesive cyclohexyl peroxydicarbonate, and the blowing agent, the copolymer was foamed by releasing the pressure and the beads were mixed with a further quantity of adhesive.

Abstract: 1414385 Injection moulding machines CONTROL PROCESS Inc 4 Dec 1973 [4 Dec 1972] 56221/73 Heading B5A Moulding apparatus comprises means for sensing the pressure of material in a mould cavity 20 and first control means for controlling second control means for controlling a parameter of the material flowing into the mould cavity, the first means controlling the second means in response to the sensed pressure and as a function of time to thereby maintain the pressure in the mould cavity in accordance with a desired relationship. In the example shown in Fig. 1, the pressure in the cavity 20 is sensed by sensing means 26, and a control unit 28 connected in circuit with the sensing means controls the operations of heating means 30 to vary the temperature of the injected material and thereby control the pressure of material within the cavity 20. The sensing means 26 may comprise an ejector pin 32 and a force measuring means 34, e.g. a transducer, connected to the control unit 28. The heating means 30 may include an electric heating element 42 supported within the inlet 16 to the mould cavity. Alternatively a steam or oil heated element (82) may be used (Fig. 6, not shown) or a band-type electrical heater (88) may surround the inlet 16 (Fig. 7, not shown). A second mould cavity 22 has an ejector pin 44 biased upwardly by biasing means 48 which may be a fluid operated piston (50), Fig. 2 (not shown) or an adjustable spring (56), Fig. 3 (not shown), or by a pair of wedges (66, 68) one of which is slidable relative to the other by adjustment means (72), Fig. 4 (not shown). Fig. 8 shows an alternative embodiment wherein the pressure in the mould cavity is used to control the size of the inlet to the mould. Thus the position of a member 96 which is slidable in a passage 102 is controlled by the pressure fluid supplied to a chamber 100 and this in turn is controlled in response to the pressure of material in the mould cavity.

[Also in Division C7] A secondary battery electrode is prepared by (a) impregnating a porous electrically conductive matrix with an aqueous solution of a metal salt end (b) treating the impregnated matrix with an aqueous solution of a carbonate, bicarbonate or sulphite to form a water-insoluble salt of the metal. The matrix may be of sintered nickel. The metal salt solution may be a hot saturated solution of nickel nitrate or cadmium nitrate containing at least 25 gm. ions/ litre of the metal ion. The matrix may be impregnated by immersing it in the solution under vacuum and draining it. The metal salt may be converted to insoluble metal carbonate by treatment with potassium carbonate solution, the matrix being afterwards dried by draining or by heating and/or dessication. Any remaining nitrate may then be reduced by treatment with a compound such as ascorbic acid which contains a -C(OH) = C(OH)- group. The metal carbonate may then be converted to the metal oxide by thermal decomposition at 600-750 F. for Ni or 850- 875 F. for Cd and this in turn may be converted to Ni 2 O 3  or Cd metal by electrolytic oxidation or reduction respectively at a voltage of at least 1À4 and a current density of at least 0À1 amps/ sq. in. In an alternative procedure the nickel nitrate may be converted to Ni 2 O 3  in two stages by electrolysis in K 2 CO 3  solution at 2-5 volts and a current density of 0À5-2 amps/sq. in. followed by electrolysis in KOH solution at 1À3-5 volts and a current density of 0À05-0À5 amps/sq. in.
