Patent DE-3030464-A1 (DE)
Inventor: ABRAHAM GERHARD DIPL ING
IPC: H01H71/32
Filed: 1980-08-12
Abstract: In order to bring about bipolar release of a holding-magnet trip device which has a permanent magnet (5), one or more release windings (1) for producing an energising flux, and a release armature (10) which is subject to the influence of at least one pulling-off spring (11), said armature (10) rests on at least three pole surfaces (7, 8, 9) in the quiescent state. At least one pole surface (9) represents one magnetic pole and the other pole surfaces (7, 8) represent the other magnetic pole, the entire magnetic flux flowing via the release armature (10). At least two pole surfaces (7, 8) are arranged inside a magnetic circuit which contains the release winding (1). The permanent magnet (5) is located between these pole surfaces (7, 8) and the third pole surface (9). Supplying an alternating current to the release winding (1) flips the release armature (10) about one of at least two different axes, as a result of the force of the pulling-off spring (11) and depending on the half-cycle of the alternating current in each case, which axes are defined by the position of one of the pole surfaces (9) of the permanent-magnet circuit and in each case one of the pole surfaces (7, 8) of the electromagnetic circuit. <IMAGE>

Title: Cooling system for copper converter opening - has individual cooling tubes floatingly arranged in refractory around opening
Inventor: PHILIP THOMAS P
IPC: C21C5/46
Filed: 1980-10-25
Abstract: The mouth of a converter is cooled using a cooling medium which is supplied to a header zone from a storage zone via a heat exchanger. The cooling medium is admitted to conduits forming a serpentine pipe embedded in refractory material lining the mouth. The used medium is passed to a further header zone for return to the storage zone for recooling and recycling. The header tanks allow for surges in the cooling system and impose a certain pressure on the cooling medium. The conduits are arranged between fins welded onto the lining so that they are free to expand and contract with temp. variations of the lining.

Patent DE-3112465-A1 (DE)
Title: Method for removing solid residues from large containers, such as hoppers, silos, tanks or the like
Inventor: NOCON WERNER
IPC: B65D88/70
Filed: 1981-03-28
Abstract: The invention relates to a method for removing solid residues from large containers, such as hoppers, silos, tanks or the like. These large containers usually have only one upper filling opening and one lower removal opening and are mainly intended for storing bulk materials. For various reasons, these can settle on the container wall and form crusts which can only be removed by knocking the residues out in pieces from the removal opening located at the bottom. This is very dangerous and time-consuming. The invention proposes a very simple method for removing the solid residues. Carrying out this method does not necessitate anyone entering the interior of the large container. According to the invention, a boring nozzle is lowered through the filling opening, from which nozzle one or more hard jets of water emerge, initially a channel which continues down to the removal opening being produced by the boring nozzle or being widened up to a sufficient width. Subsequently, the remaining residues are cut out by means of the jet of water so that they drop down and can leave the large container through the removal opening. Further measures proposed by the invention relate to the complete removal of the residues even from inaccessible edge regions.

Title: Refrigerated counter with an arrangement for humidifying an air current
Inventor: ALBERT PETER
IPC: A47F3/04
Filed: 1981-09-11
Abstract: The invention relates to an arrangement (8) for humidifying the cooled air guided in the circuit in a refrigerated counter (1). In this arrangement, water is finely atomised with the aid of vibration generators (10) according to proposals of DE-OS 2,922,971 and mixed with the cooled air. In the interests of saving the time and costs for maintenance and repair of the highly sensitive vibration generators (10), the latter are located together with their control in a slider (17) which can be inserted in an easily exchangeable fashion into a housing (14) which is permanently joined to the refrigerated counter (1). The housing (14) contains the connections (15, 16) for supplying and discharging the water. Provided in the slider (17) is a water overflow (19) which keeps the water level (18) constant above the vibration generator (10). The slider (17) is fed more water in this arrangement than is atomised by the vibration generator (10). <IMAGE>

Title: Hydraulic directional control valve
Inventor: KOETTER WOLFGANG DIPL ING
IPC: F15B13/02
Filed: 1981-09-26
Abstract: The invention proposes a pilot-controlled hydraulic directional control valve (10) for a constant flow system with internal control oil supply, the valve operating with low neutral circulation pressure. The control line (35) of a change-over valve (13) relieving the pressure medium flow to the tank (27) in the neutral position of the control slide (36) is guided via an auxiliary slide (45) which controls the control line (35) as a function of the pressures in the pressure chambers (22, 23) assigned to the control slide. While the directional control valve (10) is switching, the low neutral circulation pressure initially actuates the auxiliary slide (45) and thus blocks the control line (35), as a result of which the change-over valve (13) throttles the circulating flow to the tank (27) and the increased pressure in the feed (29) is available for reliable and rapid deflection of the control slide (36). <IMAGE>
