Title: Method for the production of steel in a basic iconverter using slag
IPC: C21C5/44
Filed: 1981-09-28
Granted: 1986-01-08
Abstract: By the present method, the basicity of the starting slag is significantly increased and the slag is kept at the saturation threshold, if possible during all the refining, but at least during the critical starting period. It is desirable to reach the MgO saturation as well as the slag saturation with CaO and calcium disilicate. At the end of the blowing, the method is carried out with a constant amount of slag per ton of steel for a given Si contents of the pig iron. A certain amount of MgO per ton of steel, according the Si contents of the pig iron, is added to the starting cast-iron together with the slagging medium, before or during the start of the refining; after the start of the refining or after the melt, the totality of the slag stays in the converter. This results, on the one hand, in the fact that the lifetime of the oven's shin is prolonged and, on the other hand, in the fact that the quantity of slagging medium required is significantly reduced. The slag adjustment is more regular and the metallurgical results are improved.

Abstract: A firearm comprises a barrel having a bore and a receiver forming an ignition chamber. A bolt is slidable in the ignition chamber and includes a striker projection for igniting a primer of the projectile. A bolt advancing mechanism comprises an arm having a first end mounted on the bolt such that a second end of the arm is movable laterally relative to the fore-aft axis. A boss is carried at the second end of the arm. An actuator member is movable in the fore-aft direction relative to the bolt and boss, and includes a first cam surface inclined relative to the fore-aft axis for urging the boss forwardly and laterally. The boss is movable laterally along the first cam surface in response to the boss becoming aligned with a lateral groove in the receiver. Such lateral movement of the boss is in a direction tending to displace the bolt forwardly. The actuator member (i) pushes the boss and bolt forwardly to shift the projectile to a firing position, (ii) cams the boss into the groove to further displace the bolt forwardly and ignite the primer, and (iii) blocks movement of the boss from the groove until ignition occurs, whereupon a second cam surface displaces the boss outwardly.

Abstract: Devices for fixing lathe tools and attachment thereof to lathes (frame-support) and automatic clamping devices (21) which preserve permanently the adjustment of tools (28), particularly the height adjustment: said adjustment of the tools may be carried out separately from the lathe. The fixing devices (21) have no removable parts and may be easily and rapidly opened and clamped by simple devices to receive a new tool set. The uniform conformation of the fixing devices, particularly their identical heights, makes possible, with a fast changing clamp (50, 51, 52, 59) provided with adhering magnets, an instantaneous and accurate change of the tools, either when proceeding to new adjustments or in the case of readjustments or even during normal working conditions: thereby, a minimum of down time periods of the lathe is achieved.

Title: Sintered material for electrical contacts and its method of manufacture
IPC: H01H1/02
Filed: 1984-02-01
Granted: 1986-06-18
Abstract: AgCdO based contact elements are replaced in contactors and small circuit breakers with CdO-less type elements which exhibit little burn-off in the arc, a low welding force and minimal heating when carrying continuous current. However, known AgSnO2 contact materials do not have optimum values in all operationally important properties. In these contact materials a more firmly adhering oxide layer occurs as compared with AgCdO. The invention relates to a sintered compound material for electrical contacts, consisting of AgSnO2Bi2O3CuO and containing at least one other metal oxide additive which sublimes below the melting temperature of silver. The SnO2, Bi2O3 and CuO are globularly precipitated in silver material structure zones having a maximum diameter of 200  mu m, and the metal oxide additive is distributed on the surfaces of the boundary regions of these microscopic silver zones.

Abstract: Chairlift or gondola lift with a carriage supporting a gondola or a chair and having a detachable grip for coupling on a continuously moving cable. In the terminals the carriage is uncoupled from the cable and it runs on a transfer rail. This transfer rail is equipped with friction drive wheels disposed along the carriage travel path for engaging the friction face of a running plate rigidly secured to the carriage so as to brake, accelerate or drive the carriage on the rail. During the night or bad weather periods a cover plate covers the friction face of the carriages disposed on the line and this cover plate is raised away in the terminals to clear the friction face. For removing the snow or ice which covers the friction face and hinders the correct friction drive of the carriage a brushing or rubbing device may be disposed along the carriage travel path so as to brush the friction face.

Abstract: The invention relates to a penetrator (1, 11) made of heavy metal, such as, for instance, tungsten heavy metal or depleted uranium, for driving-cage projectiles which have the penetrator led by the driving cage in the gun barrel. The driving cage (6, 12) detaches itself from the penetrator after the launch. The penetrator (1, 11) shows lower strength and higher ductility in the middle portion (d) of its length than in its head portion (c) and, in its tail portion, it shows higher strength and lower ductility than in its middle portion (d) and lower strength and higher ductility than in its head portion (c). This shall decrease the risk of fracture when striking an armour. The varying strength values in the head portion (c), in the middle portion (d) and in the tail portion (e) are obtained by cold-hammering under varying degrees of deformation, by sintering from various powder mixtures or by varying partial heat-treatment in the various portions (head portion c, middle portion d and tail portion e), and these measures can be applied individually or in combination. At least one pilot core (14, 15) which is only loosely connected to the penetrator (1, 11) can also be fitted to the head portion.

Patent EP-0160043-B1 (EP)
IPC: F28C1/00
Filed: 1984-10-15
Granted: 1991-07-31
Abstract: A process is developed for continuously removing and recovering respectively ammonia from aqueous ammonia waste water by stripping the waste water in a column, using heat absorption from already stripped waste water and by using a gas flow, e.g. an air flow, flowing in counter current with the waste water through the column. Especially in view to the presently desired control of environmental pollution a know process involves such high investments that an economic solution often automatically fails. The invention eliminates such serious disadvantages whereas moreover an economically more valuable product can be obtained, e.g. water with a high concentration of aqueous ammonia. This is achieved according to the invention in that the heat transfer is effected by a gas flow which, by direct contact in a packed bed, absorbs heat from the effluent liquid whereafter this absorbed heat is again transferred to the influent liquid. Preferably the gas flow consists of a recirculating air flow having a high temperature, said air flow transferring heat in a part of the column which is provided with a packed bed, to the waste water to be stripped, flowing in counter current to the low temperature waste water, whereafter the same air flow, now having a low temperature, recuperates in another part of the column, likewise provided with a packed bed, heat from the stripped liquid, now having a high temperature, also in counter current.

One of the main electrodes (5b) and the auxiliary electrode (6) are connected to a trigger pulse generator (EHT) driven by a remote control (4) via a synchronization pulse generator (3). The discharge between the main electrodes (5) primed by a preliminary spark, generates an acoustic pulse through the liquid medium of the transducer on the ground where the paraboloid (1) is engaged. So the transducer generates seismic waves utilized for shallow prospecting both on land and underwater.
