Abstract: In an injection-metallurgical process for the desulphurisation of steel, lime (CaO), opt. together with fluorspar (CaF2) is injected by means of a neutral carrier gas such as argon or nitrogen beneath the surface of the melt. The amt. of calcium injected is sufficient to remove the major part of the sulphur in a melt. A cpd. comprising non-oxidically combined calcium, such as calcium-silicon, calcium carbide or calcium cyanamide is then injected which acts as a source of elementary calcium which dissolves in the melt and/or with any remaining inclusions to render these harmless and to improve the flowability of the steel. The process is economical and is esp. useful in the treatment of low carbon and low silicon aluminium-treated steels. Good desulphurisation is achieved together with morphological conversion of remaining inclusions, esp. the transformation of aluminium oxides into spheroidal complex calcium aluminates which to not have the same tendency as Al2O3 to combine to form large aggregates. The process is esp. useful for the prodn. of aluminium treated deep-drawing steels, e.g. of the type used in the prodn. of car bodies.

Abstract: The present invention comprises a method of transmitting information from a central ground station to at least one mobile auxiliary ground station via at least one base station. The auxiliary ground stations are located within the transmitting range of at least one base station, and are provided with a receiving device having a control unit and a memory. In accordance with this method, a block of messages cyclically repeated within a time frame is transmitted over a single frequency from the central ground station to the base stations. Each of the messages within the block includes an address code which corresponds to the area code of the region adjacent a corresponding base station. The base stations transmit the block of messages over a single frequency to receiving devices located in the mobile auxiliary ground stations where those messages corresponding to a selected area code are recorded and then played back.

This tube is formed with a pair of axially spaced and radially inwardly open grooves both having axial lengths equal at least to a predetermined axial distance, and the tube is further formed at these grooves with respective radially throughgoing apertures. A piston subdivides the interior of the housing into a pair of compartments and has a stem extending axially rearwardly in the tube. This piston is axially displaceable in the housing through an axial stroke at most as long as the distance corresponding to the axial lengths of the grooves. The piston is formed with a pair of throughgoing passages each having one end opening at the stem into a respective one of the grooves and another end opening into a respective one of the compartments. The piston is provided with a pair of check valves set up so as to prohibit flow between the ends of the passages except when either of the passages is pressurized from the respective one end. A collar surrounds this tube and is rotatable thereon about the axis. This collar is formed with a pair of angular inwardly open grooves respectively aligned with the apertures and is provided with a pair of connections respectively opening into the inwardly open grooves of the tube.

Abstract: A feeder consisting of exothermic heating composition keeps the cast material disposed in the feeder liquid until completion of the shrinkage feed of the casting. To avoid contamination of the moulding sand (2) on separation of the casting (1) due to burnt feeder disintegrating into irregular fragments, the make-up of the heating composition is so chosen that the heating composition during the shrinkage feed sinters together and the burnt feeder is given such a high strength that it can be detached as a whole or in large pieces capable of being sieved out. Various ways in which the constitution of the heating composition is adjusted to achieve sintering at the temperature reached are described with examples of constituents. <IMAGE>

Abstract: A magnetoelastic force transducer is made of two identical, cylindrical bodies of magnetic material which are held together by means of a stud bolt. In an axially extending and concentrically located inner space there is placed a bobbin with two measuring windings, connected in opposition, and an excitation winding supplied with alternating current. The interior of the transducer is shaped such that a thin cylindrical tubular wall is formed immediately opposite to the respective measuring winding in each one of the bodies. When the transducer is force-loaded via the stud bolt, a compressive stress arises in one of these tubular walls and a tensile stress arises in the other tubular wall. This influences the magnetic conditions such that a signal is obtained from the measuring windings which is proportional to the applied force. In order to eliminate a possible measuring signal at zero applied force, means is provided to move the bobbin in the axial direction. A natural prestress can be imparted to the core with the aid of a built-in spring means and an adjusting screw.

Abstract: A compound pump mechanism is provided adjacent the inlet ends of concentrically positioned inner and outer stuffing horns or tubes of a meat encasing machine. The first pump mechanism is in communication with a source of conventional meat emulsion, and is powered by a vertically disposed power shaft. This power shaft extends into the housing of a second pump mounted adjacent to, and preferably on top of, the first pump housing. The drive shaft of the first pump housing operates the pump mechanism in the second pump housing. Both pumps have inlet and outlet ports for conveying material to be pumped. The outlet ports of both pumps discharge the pumped material into a block element which slidably receives the ends of two concentrically positioned inner and outer stuffing horns. The pumped material from the second pump housing delivers pumped material into the end of the inner stuffing horn, and the pumped material from the first pump delivers meat emulsion or the like into the the end of the outer stuffing horn. The housing of the upper pump or second pump contains a vane-type pumping mechanism. The pumping capacity of that pumping mechanism is selectively controlled by pivoting the position of the second pump housing with respect to the first pump housing.

Abstract: There is a requirement for a simple way of indicating the operating state of a solenoid-controlled valve. The magnetic field of the solenoid can be indicated using an indicator consisting of a small annular permanent magnet 1 which, with a gap 4, is arranged rotatably about a bar 3. The indicator is placed on or in close proximity to the coil in the solenoid valve. If current is supplied to the solenoid coil, imbalance will arise in the influence of the magnetic field of the solenoid coil on the annular magnet 1 in relation to the bar 3 depending on the gap 4, and the annular magnet will begin to rotate. The casing 5 of the magnet 1 can be entirely or partly transparent. The magnet 1 can be two-coloured in order for its rotation to be more clearly visible. <IMAGE>

Abstract: Laser-warning method and a laser-warning arrangement, which laser-warning arrangement is intended to warn of laser light from a laser beam source which is used for guiding projectiles, missiles and the like, for example laser light from a pulsed laser beam which is directed towards a target area. The time for the laser beam to reach the laser-warning arrangement, the so-called impact time, is calculated from a first amplitude value, measured at a first point in time, of the scattered light from the laser beam and a second amplitude value, measured at a second point in time, of the scattered light from the laser beam, and the measured time difference between the said first and second points in time on the basis that the amplitude raised to a constant is proportional to the distance to the laser beam according to the equation D = K . A<n>, where K and n are constants, D is the perpendicular distance to the laser beam and A is a measured amplitude value. The laser-warning arrangement comprises a rotatable optics system with two light inputs, a fixed detector system which detects the magnitude of the light coming in via the light inputs of the rotatable optics system and transmitted through the optics system to the fixed detector system, and an evaluation unit which determines the impact time in accordance with the above equation. The optics system comprises, counting from each light input, a first cylindrical lens, prism, reflector, filter, second cylindrical lens, diaphragm and glass block.
