Abstract: The invention relates to a load control device with a throttle valve (9) determining the output of an internal combustion engine, which is connected in a rotationally fixed manner to a throttle valve shaft (36) supported in the throttle valve housing, the throttle valve shaft (36) being influenced by a control element which acts in concert with a driver (4) coupled to an accelerator pedal (1). The throttle valve (9) can be adjusted by way of a first and second mechanism (33, 34). Outside the idling control range a wheel slip control function (ASR) is performed by the first mechanism (33), the internal combustion engine being throttled down. The electric motor (14) is frictionally connected to the throttle valve shaft (36) by way of the first mechanism (33) only if the second mechanism (34) is disconnected from the throttle valve shaft (36). In the idling control range only the second mechanism (34) is frictionally connected to the throttle valve shaft. <IMAGE>

Abstract: An improved memory system for use in a data processing system has two memory banks (30,31) and corresponding error correction circuitry (34,35) associated with each. Data words of a block thereof are stored in the memory banks in an interleaved fashion wherein alternating words are stored in one bank and the intervening alternating words are stored in the other bank. During a WRITE operation the memory is controlled so that the first data word of a block stored in a memory bank uses a late write technique, and all subsequent data words thereof use an early write technique. During a READ operation, pairs of data words are read and checked for errors simultaneously, and are then supplied in a pipelined manner.

Abstract: A multi-ferrule structure comprising a plurality of ferrule units(40: 40a, 40b, 40c, 40d) each for a single optical fiber. The ferrule units are disposed in contact with one or more adjacent units in such a way that the respective axes(O₁, O₂, O₃, O₄) of the ferrule units are in parallel with each other in one and the same plane(P). The ferrule units make one multi-ferrule set(42). The maximum deviation of the distance between optical axis of the optical fibers inserted in the respective ferrule units of the multi-ferrule set is very small. When a number of optical fibers are connected with the same number of other photoconductive components by using the multi-ferrule structure, the positioning accuracy for abutting connection is remarkably improved. In addition, the multi-ferrule structure is small in size and compact.

Abstract: A method of making a hollow article, for example, a hollow airfoil, from first and second preformed sections involves a first precursor (seal) bonding step where a low external pressure and internal vacuum are utilized to form a substantially gas impermeable seal bond between opposing bonding surfaces of the sections with only limited distortion of one of the sections and no distortion of the other section, a diffusion bonding step where a high external and high internal pressure is utilized to form a complete parent metal diffusion bond between the bonding surfaces without distortion of either section and an inflation step where a high external and high internal pressure are utilized to remove the limited distortion from the affected section without distortion of the unaffected section. The inflation step and diffusion bonding step can be combined into one operation to provide a two step method of making the hollow article.

Abstract: A headed thermoplastic tube (29) is formed solely from a thermoplastic extruded, stretched, cylinder (3) by positioning the cylinder over a forming mandrel (5) with an exposed portion (13). The inner surface (15) of the exposed portion is heated above the glass transition temperature of the thermoplastic material to render the inner surface molten while the outer surface provides support for the exposed portion of the cylinder. The heated exposed portion is then shaped into a conical shape (25), such as by heating the outer surface, thereby releasing internal stresses, and pressure is applied to the conical shaped exposed portion to form a headed thermoplastic tube. The headed tubes produced have a body portion (30), shoulder portion (31) and neck portion (33), without any seams, all of which are formed from the starting thermoplastic extruded, stretched cylinder.

A common distillation column is preferably provided for both separations. The preferred apparatus comprises the fixed-bed reactor and, arranged alongside the latter, the distillation column, in which the receiver for pure tetrachlorosilane, the feed line for liquid reaction phase, the outlet line and recycling line for trichlorosilane into the reactor, the feed line for gaseous dichlorosilane containing trichlorosilane and, at the column head, the condenser and the receiver for dichlorosilane are arranged one above the other. Catalysts which are particularly suitable for the disproportionation of trichlorosilane are those of alkylaminotrialkoxysilanes.

Abstract: In accordance with illustrative embodiments of the present invention, a method of determining fracture behavior from downhole pressure measurements that are made during a hydraulic well fracturing operation includes pumping fracturing fluids at a constant rate under high pressure against a formation to create fractures therein, and obtaining measurements representative of downhole pressures as pumping progresses. The logarithmic derivatives of such pressure measurements are used to determine the type of fracture behavior, as well as the onset of screenout where the fracturing fluid carries a proppant. In-situ stress or closure pressure also can be determined by finding a value thereof which makes a logarithmic net pressure plot have the same slope as the logarithmic plot off the values of the pressure derivatives.

Abstract: The present invention is a system which uses a random noise test target 16 to align sensors 10 and 12 by performing mathematical cross correlations between computer rotated images produced by the sensors 10 and 12. The system 48 includes a computer 58 which executes a loop including mathematically rotating one of the images, computing a correlation between the rotated image and a reference image and determining the peak in the correlation. The peaks of the rotations are scanned to determine a global maximum, and the maximum is used to interpolate a true subpixel peak. The interpolated rotational cross correlation peak is used to determine values of two dimensional and rotational movement of one of the sensors 10 and 12 necessary to align the sensors. The values are used by a motor drive control unit 60 to move the sensor 10 or 12 and it is fixed in place. Once the sensors have been aligned and fixed in place, the system 118 computes the cross correlation of segments of  the image to determine delay values and an interpolation filter coefficient values which are stored in a permanent storage device 120. The coefficients are used by an correction circuit 122 to correct for regional or spatially varying alignment errors during real time image processing by the imaging system.
