Title: Process for the repair of slide plates
Inventor: EVERTZ EGON
IPC: C21C5/46

Granted: 1987-09-29
Abstract: ABSTRACT OF THE DISCLOSURE          The invention relates to a method for repairing slide plates of metallurgical containers.  These types of slide plates consist of refractory material and have a passage opening for the discharge of the liquid metal, which is usually steel. Owing to corrosion and radial cracks, which originate at the passage opening, these slide plates 5 become worn after a lengthy operating time.  In order to be able to further use them to a large extent, the invention provides a bore, in the area of the opening, extending as far as the edge of the rim 6 of the slide plate, whilst the remaining refractory material is retained.  Into this bore there is poured a refractory casting mass, the grain structure of which has a particular relation to to pore size of the retained refractory material.  The essential fact is that the solid bodies of the refractory casting mass are predominantly smaller than the open pores, cut by means of the boring process, of the retained refractory material and can penetrate into the pores. This produces anchoring, which reliably prevents the consolidated refractory casting mass from subsequently peeling off the retained refractory material.

Abstract: ABSTRACT OF THE DISCLOSURE          A weighing system includes a weighing pan connected to a rigid armature by a mechanical filter constraining the armature to motion along a reference axis with respect to a housing and damping out transient forces along this axis resulting from the placement of objects on the pan.  The mechanical filter includes spring and damping elements that provide a low-pass filter, that is, one that efficiently and quickly eliminates high frequency oscillations.  In one form, the mechanical filter couples the pan to the armature.          Because of this connection, friction in the mechanical filter does not result in frictional errors in the weighing measurement.  In another form, a mechanical linkage couples the armature to the housing.  A force transducer, comprising a pair of complementary opposed surfaces having a mutual separation which is related to the force across the transducer, is coupled between the armature and the housing.  Coupled to the transducer is a position sensor which generates a signal representative of the separation between the complementary opposed surfaces of the transducer.

Abstract: Abstract The invention relates to a device for arc welding with one or more fusible electrodes (15) which are in each case supplied from an alternating-current source (14) having a falling characteristic.  The feed rate of the electrode (15) is regulated for constant arc length as a function of the arc voltage.  Via a further regulator (37), the deposition efficiency is regulated by supplying the regulator (37) with the feed rate as actual value and changing the welding-current intensity as a function of this value.  The change in welding-current intensity leads to an increase or decrease in arc length which, in turn, is compensated via the first regulator by changing the feed rate.

Abstract: REPLACEABLE SEALS FOR LADLE HEATERS                   ABSTRACT OF THE DISCLOSURE           Ladles and the like into which hot metal is teemed are refractory lined to withstand the high-temperature effects of the hot metal. Prior to teeming of the hot metal into the ladle, the ladle is heated by applying a flame to the interior thereof, which flame is provided by a burner that directs the flame through a ladle cover plate having a substantially flat surface covered with heat-insulating refractory material, which surface is brought into sealing engagement with the ladle.  This seal minimizes the amount of heat energy that escapes from the ladle to render the preheating operation more efficient. The rim of the ladle, which contacts in sealing engagement the heat-insulating refractory material of the ladle cover plate, causes wear and damage to the heat-insulating refractory material.  Deposits of slag and metal build up along the rim of the ladle and this further contributes to the wear and damage to the heat-insulating refractory material when the ladle cover plate is brought into sealing engagement with the rim of the ladle.  The present invention provides a ladle cover plate having a ring of refractory modules that are individually, removably secured to the surface of the ladle cover plate which ring mates with the ladle rim when the ladle cover plate is brought into sealing engagement therewith.        Consequently, when excessive wear or damage occurs the modules may be removed and replaced in an efficient and economical manner.

Abstract: ABSTRACT OF THE DISCLOSURE         A bulk syrup delivery system in which a compart-mentized tank delivery truck includes a plurality of separate compartments or tanks, generally one for each of several different types of soft drink syrup.  One multichannel delivery hose, having one channel or passage-way for each type of syrup, extends from a hose reel on the delivery truck to a delivery receptacle at the account.          The account has a plurality of separate storage tanks, each of which is coupled to the delivery receptacle, which is designed to couple to the end of the delivery hose, such that each compartment in the delivery truck  couples to the proper storage tank in the account.  A plurality of separate check or closure valves are installed in each side of the coupling between the hose and the delivery receptacle, such that flow therebetween is prevented until the valves are opened.  The compartments in the delivery truck are pressurized  (e.g. 100 psi), such that the syrups flow from the truck into the account storage tanks until the latter are full, after which the hose/receptacle connection is terminated.  Each of the fluid channels or passageways is coupled to a separate delivery meter such that the amount of each type of syrup is metered during the delivery.  The meters can be operated in conjunction with a load ticket carried by the driver, the insertion of which into the meter arrangement resets to zero each of the meters and also enables operation of the delivery system.

Abstract: ABSTRACT An improved semi-submersible unit for use in offshore operations which has a significantly reduced susceptability to heave motions in wave periods which are most likely to be encountered during practical operation conditions.  The unit consists of a lower hull or hulls supporting vertical buoyant caisson which also support an upper deck or platform which supports and is supported by a centrally disposed, large diameter buoyant caisson which contributes a significant portion of the total water plane area of the vessel when it is submerged to its operational draft.   The vessel may be configured for offshore drilling operations, diving support, and various other offshore support functions.  When configured for the offshore drilling operation, the central column serves as boy a buoyanch chamber and as a primary storage chamber for tubular products which are associated with the drilling function.  This clears the deck of the vessel for other operations and  introducing a less hazardous method  for handling  tubulars than  in previous designs. The central caisson has an interior annulus which is open both to the drill floor and the sea through which operations may be carried out.  The improved semi-submersible vessel exhibits significantly less heave in operational wave conditions than existing semi-submersibles of similar water plane area and displacement.

Abstract: INSTRUCTION PREFETCH OPERATION FOR BRANCH AND          BRANCH-WITH-EXECUTE INSTRUCTIONS                    Abstract A method and apparatus are described for expand-ing the capability of an instruction prefetch buffer.          The method and apparatus enables the instruction prefetch buffer to distinguish between old prefetches that occurred before a branch in an instruction stream and new prefetches which occurred after the branch in the instruction stream.  A control tag is generated each time a request for an instruction is sent to a storage.  The returning instruction has appended thereto the original control tag which is then compared to the current value of control tag in the instruction prefetch buffer.  If the two values match, then this is an indication that a branch has not occurred and the instruction is still required.          However, if the two values or the control tag are not equal, then this is an indication that a branch in the instruction stream has occurred and that the instruction being sent from storage to the buffer is no longer required.  The method and apparatus are also applicable to the use of branch-with-execute instructions wherein a subject instruction is execut-ed immediately following the branch-with-execute instruction.  The execution of this subject instruc-tion before the branch target instruction enables the system processor to continue operating while it is waiting for the branch target instruction.
