Patent SE-7608145-L (SE)
Inventor: ROSCOE C
IPC: C25D5/00
Filed: 1976-07-16
Abstract: Sludge formation is reduced in the continuous production of iron by electrolysis of a ferrous electrolyte in a electrodeposition cell by cooling spent electrolyte returning to a holding or regeneration tank, and heating reconstituted electrolyte returning to the electrode-position cell. By reducing the temperature of the spent electrolyte the rate of hydrolysis of ferric ions to form oxides of iron, called sludge, is reduced, thus increasing the interval between periodic cleaning of the electrolyte regeneration system and the electrodeposition cell. In preferred forms of the invention heat energy is transferred from the spent electrolyte to the reconstituted electrolyte by means of at least one counter flow heat exchanger in the form of a hollow cylinder containing a plurality of tubes made of titanium. There may be a controllable cooling device disposed between the holding tank and the or the last heat exchanger for maintaining the temperature of electrolyte in the holding tank at a selected value.

Abstract: There is disclosed an apparatus for supporting roll chocks of a work roll in a roll stand housing. This apparatus includes a thrust transmitting head member between the roll chock and a rolling force effecting mechanism such as a screw of a screw down mechanism. The head member has a spherical surface at one end in contact with a mating spherical surface formed at one end of the screw. These spherical surfaces have different radii to make point contact therebetween and to enable rolling contact movement between the head member and the screw in the rocking motion of the roll chock caused by a force in a workpiece generated during a rolling operation, to thereby provide more accurate measurement of tension in the workpiece being rolled by employing force sensing devices acting on the roll chocks. The head member also has inclined surfaces at the other end thereof in registration with mating inclined surfaces formed at one side of the roll chock. The registration of these mating inclined surfaces make it possible to center the roll chock in the roll stand housing.

Abstract: The invention concerns a method and a device for the introduction of a powder material into a pneumatic transport line with the aid of a screw transporter 1 that feeds the material into a mixing chamber 2 attached to the line, into which chamber pressurised air is blown for dispersion of the powder. According to the method, the frictional losses in the screw transporter are monitored by measuring the load on the drive motor of the screw 8, whereby frictional losses are prevented from exceeding a predetermined value in that at least one of the quantities that determine the load is controlled, preferably through pressurised air being blown into the screw transporter and/or the rate of revolution of the screw being reduced. <IMAGE>

Abstract: The invention concerns a procedure and apparatus, which by use of a heated sensor, determines the flow of heat between a body covered in a thermal resistive layer and its surroundings, such as when a person suffers heat loss particularly in connection with going out of doors. The flow of heat given off by the skin is simulated by a corresponding electric current (I). The skin's heat resistance is simulated by a corresponding electric resistance (R) through which the above current flows. The body temperature and the skin's external temperature are simulated by two corresponding voltages (Ub and Us).The sensor body is heated by the current (I) which flows through the transistor (T1), while the temperature arising (Us), which corresponds to the skin's external temperature, is detected by the linear temperature transmitter (D1). The voltage (Ub) corresponding to the body's temperature is produced by the voltage dividers (R2-R3). The operational amplifier (OP1) seeks to bring about parity between on the one hand, the voltage (Ub), and on the other hand, the sum of the voltage (Us) and the voltage across the resistance (R); these conditions correspond to what is being simulated.The current (I) is measured by an instrument in the flow of heat, or one graduated in temperature, where the temperature corresponds to that in a still air mass which would cause a similar level of cooling as the relevant climate.<IMAGE>

Abstract: For preparing the novel bestatin compounds of the formula having R1 and R2 in accordance with the preceding Patent Claim 1, an alpha -hydroxybeta -amino acid of the formula is used as the starting material. The latter is condensed, optionally after having protected the functional groups which are not to participate in the subsequent reaction, with a beta -amino acid of the formula using a peptide-linking method. Protective groups which may optionally be present are subsequently removed. The optically pure diastereoisomers can be readily obtained from the compounds of the formula (III). The alpha -hydroxybeta -amino acids can be prepared by hydrolysing a corresponding cyanohydrin whose amino group is optionally protected. The novel compounds inhibit certain enzymes which decompose bleomycin and in this way amplify the anti-tumour activity of the bleomycins.

Abstract: The measuring arrangement for determining terrestrial refraction is applied in geodesic measurements (trigonometric altitude transfers, in staking out and in precision tachymetry, steering construction machinery by means of a laser beam, precision levelling). The measuring arrangement includes a geodesic measuring instrument (T), an electronic processor and an appliance (S, E) for measuring the transit-time difference of sound waves. After the sound waves generated by a sound transmitter part (S) have traversed layers of air (e.g. at different altitude) on a representative path, the time difference is measured and employed to determine the refraction. The sound receiver part (E) includes two microphones (M1) and (M2) which are positioned vertically above one another at altitudes (Z1) and (Z2) above the surface of the earth in the immediate vicinity of the electronic tachymeter. Using the arrangement it becomes possible to determine, for a particular range as defined from the position of the instrument, continuous measured values from which the instantaneous refraction can be inferred. Terrestrial refraction can be determined more accurately than in conventional methods for engineering geodesic and constructional work. <IMAGE>
