Abstract:
A cooling plate for refractory-lined shaft furnaces includes a first cooling plate element facing the inside of the furnace and a second, rear cooling plate element, where in the cooling plate elements are welded together. A cooling channel is formed between the first and second elements of the cooling plate. Pipe elements are connected to the coolant inlet and coolant outlet. The first cooling plate element is a bloom with a plane front side facing the inside of the furnace, and the cross-sectional area of the cooling channel is larger in the end regions thereof than in the center region, as viewed along the longitudinal extent of the cross-section.
Abstract:
A method for monitoring thermal overload of an electric load element in a motor vehicle containing other electric consumers, which can be switched into a stand-by phase is disclosed. The load element is monitored by a control device using a calculated load temperature parameter. During a first operational phase, a power loss of the load element or a quantity that is essentially proportional thereto is evaluated for calculating the load temperature parameter. During one or more stand-by phases, the control device is switched with essentially no current between the first operational phase and a second operational phase. After the control device is switched on in the second operational phase, at least one quantity, which is characteristic for the moment of switching on, is evaluated for calculating the existing load temperature parameter.
Abstract:
The invention relates to a Laval nozzle for thermal spraying and kinetic spraying, especially for cold gas spraying, with a convergent section and a divergent section. To achieve a better degree of application effect, at least a portion of the divergent section, according to the invention, has a bell-shaped contour.
Abstract:
A fastening device for fastening a fuel injection valve in a bore in the cylinder head of an internal combustion engine, in which the fuel injection valve has a longitudinal axis. A clamping jaw is acted upon by a fastening force, and the clamping jaw rests with at least one support face on a support point of the fuel injection valve, so that the clamping jaw is pressed with its support face against the support point. The support point on the fuel injection valve (5) is embodied linearly, and the line is straight and in its imaginary extension intersects and is perpendicular to the longitudinal axis of the fuel injection valve.
Abstract:
A cooling plate for shaft furnaces, in particular, for blast furnaces, provided with a refractory lining, comprising cooling channels loadable with a cooling medium, wherein at least the front side facing the interior of the furnace is comprised of an ingot, produced preferably of copper or a low-alloy copper alloy and provided with grooves for receiving refractory material, is to be further developed such that it can be produced with a minimal material expenditure and a minimal manufacturing expenditure and can be easily mounted, and that with it a higher cooling capacity with reduced cooling medium throughput can be realized, wherein the own heat uptake is limited such that a significantly longer service life can be obtained. For this purpose it is suggested that two through-shaped rolled sections with their domed areas facing outwardly, respectively, are welded together and that bores for receiving the ends of pipe connector pieces are introduced into the backside supplemental section and the ends welded thereto, and that the free ends of the rolled sections are closed off by caps.
Abstract:
In order to configure a bell and hopper for shaft furnaces, in particular, blast furnaces, comprising a charging bin with a feed tube, a rotating chute carrier with rotary drive, a swiveling chute in the interior of the furnace with drive means arranged external to a housing, in a less failure-prone and a wear resistant way, the drive means for the swivel movement of the chute are to comprise: at least one motor (7) which drives by a respective pinion (8) a crown gear (9), wherein the crown gear (9) engages the spindle gear wheels (11) of at least two spindles (13) distributed about the periphery of the bell and hopper external to the rotating chute carrier (3) for generating a lifting and lowering movement of the spindles, as well as means (14, 15, 17, 21) for transmitting this vertical movement of the spindles onto the tilting shafts (22), which penetrate the inner wall (24) of the chute carrier (3) and from which the chute can be suspended, for generating a swivel and tilting movement of the chute.
Abstract:
The invention relates to a pig casting machine comprising at least one endless conveyor belt (2), on which pig casting molds (3) are fixed, for conveying pig casting molds from a casting station (4) to a pig removal station and vice versa, wherein each pig casting mold is filled with molten metal as it passes through the casting station with the mold cavity facing upwards, in addition to a device for cooling the pig casting molds before, during and/or after casting, wherein the pig casting molds are embodied having a thin wall. According to the invention, in order to increase output and to be able to cast heavy metals in such a pig casting machine, the pig casting molds (3, 112, 207) are designed to receive molten metal at a melting temperature above 1,000° C.
Abstract:
A method of and a circuit arrangement for data transfer between a master means and slave means, in which bit sequences are transferred each having an address field for addressing the respective slave means to be controlled, a control field for control information, and a data field. The data bit number of the data field may be different depending on the addressed slave means. The bit sequences transmitted from the master means are read back directly to the master means, so that the occurrence of corrupt bits in the bit sequence is recognized and a transfer of the bit sequence recognized as corrupt to the addressed slave means can be prevented.
Abstract:
A device for the selection of address words each having n bit locations and serving for addressing m different receiving locations of a digital communication module, in at least one of the receiving locations, including a digital acceptance module through which address words can be selected. The device has an address word segmenting module through which each address word received by the receiving location can be subdivided into s address word segments with b segment bit locations each, wherein b=n/s and n is an integral multiple of s. The device further has z digital segment filters whose inputs can each be fed with an address word segment, with each segment filter having the function of examining one address word segment each with respect to conformity with a predetermined segment bit pattern, and a filter output signal being available at the output of the respective segment filter, which in accordance with the examination result is either a conformity signal or a non-conformity signal. Additionally, the device has an activation module through which those segment filters can be activated during the duration of the respective address word segment to be assessed which carry out an examination with respect to such segment bit patterns which can occur in the address words acceptable for the receiving location in consideration, in the respective address word segment to be assessed. Finally, an evaluation module through which the output signals of the respective segment filters activated for the assessment of an address word can be evaluated with respect to the presence of an address word that is acceptable for the receiving location in consideration.
