Abstract: Metal-oxide varistor compositions having a characteristically low voltage drop and low leakage current contain a reaction product which is produced by sintering a mixture of zinc oxide, bismuth oxide and other metal oxides and by the addition of 0.5 to 500 ppm by weight of aluminium or 0.1 to 500 ppm by weight of gallium, or a maximum of 100 ppm by weight of a mixture of both. Metal-oxide varistors manufactured from this composition exhibit a ratio of the voltage for producing a current intensity of 2.7 x 10<2>A cm<-2> to the voltage which produces a current density of 1.33 x 10<-4>A cm<-2> of 1.9:1 or less. Overvoltage suppressors which are produced using this material require no series-connected spark gap, as is otherwise normal.

Abstract: A method is described for stimulating the appetite of sucking pigs and for guaranteeing that the sucking pigs are provided with sufficient liquid, by offering the animals an approximately isotonic aqueous solution ad libitum starting when the sucking pigs are one day old up to week six. This aqueous solution has a pH of 2.0 to 4.0 and contains an iron/glutamic acid compound at a concentration of not more than 2% Fe. The solution is palatable to the animals, and their stimulated appetite results in a considerably better weight gain in comparison with sucking pigs who have not been given this solution ad libitum. Moreover, a dilutable aqueous iron salt solution is described for carrying out the appetite-stimulating method, which contains ferric glutamate at a concentration of 20 mg of divalent iron per ml and has a pH of 2 to 2.5.

Abstract: 1532383 Voltage measuring BBC BROWN BOVERI & CO Ltd 5 July 1977 [7 July 1976] 28149/77 Heading G1U A voltage equal to the average of a plurality of input voltages is produced, delayed and compared individually with each input voltage. Any difference larger than a pre-set amount causes the corresponding input voltage to be disconnected. The system described is a redundancy system in which ideally the input voltages would be identical. Excessive differences indicate faults and the arrangement described prevents the average signal changing excessively when a fault does occur.

IPC: B21F27/12
Filed: 1980-01-07
Abstract: The invention relates to a method and apparatus for the manufacture of a screw-line shaped reinforcement spiral out of metal wire for the reinforcement of concrete pipes or columns. The wire is, while subject to tensile stress, wound onto a cylindrical last whose diameter is equal to the inner diameter of the spiral. The wire, before coming onto the last, passes over a roll that prestresses the wire to a curve of such a small diameter that, after the wire has been taken off the curve, a tension tending to bend the wire in the direction of bending of the reinforcement spiral remains in the wire. The winding takes place so that at the immediate proximity of the initial end of the last the wire passes over rolls. The first roll, whose projection is partly outside the projection of the mantle of the last and which gives the wire a curve radius smaller than the radius of the last, makes a tension bending in the wire in the direction of bending of the reinforcement spiral which bended remain in the wire. The subsequent rolls whose projections are inside the mantle of the last or are in contact with same, jointly provide a curvature whose curve radius is at the beginning larger than the radius of the last but becomes gradually smaller and, at the last roller becomes the same. The wire is wound onto the last as guided by rolls placed at the initial end of the last and positioned radially in relation to the last. The rolls provide the winding with an opening tension effective in the axial direction of the spiral, because the rise of the winding is at the beginning or at a part of the first winding, larger than the diameter of the wire but after a few windings, the rise is the same as the diameter of the wire. One or some of these last-mentioned windings are pressed against the last by means of a roll. The roll is, at the end of the roll facing towards the final end of the last, provided with a flange that penetrates between the windings and thereby causes gliding of the windings placed behind the flange on the last by the width of the flange and at the same time bending the windings in the axial direction of the spiral.

Abstract: Process for the chemical and thermal treatment of metals and alloys which can be used in machine construction and metal treatment operations in order to increase the service life of metal coatings, in particular a process for applying a wear-resistant coating of titanium carbide or titanium carbonitride to workpieces made of sintered hard alloys with the composition WC-Co, WC-TiC-Co or WC- TiC-TaC-Co. The essential feature is that the workpiece is treated in a closed reactor at a pressure of between 1.3 x 10(-3) Pa and 1.3 x 10(2) Pa at a temperature of 1100-1250 degrees C. The workpiece is first treated with a hydrocarbon- containing gas, such as methane, and then with titanium chloride. The latter is prepared by treating metallic titanium, which is placed in the reactor with the workpiece, with carbon tetrachloride. The workpiece, now coated with titanium carbide, is again treated with a gas containing a hydrocarbon or nitrogen, e.g. nitrogen gas itself. The process can be used in industry when making hard alloy components and in the machine construction sector where hard alloys are used for making tools intended for machining objects made of metals or alloys.
