Abstract: 2.1. It is known to mill the inner wall of a pipeline in accordance with the cross-sectional contour, the width of the milled region corresponding to the width of the milling head. Owing to the high forces to be applied or the enormous loads acting on the milling head, only a narrow milled region is possible during one milling-head rotation. Thereafter, the milling head rendered inoperative and the entire device is advanced by the milling-head width. Naturally, the interruptions to the actual milling operation are relatively lengthy in this case, so that only a limited output is possible. In contrast, with the novel method the output should be increased. 2.2. For this purpose, provision is made to cut in one rotation a plurality of adjacent grooves, to shear off the intermediate webs produced and to carry away the resulting waste. A device for carrying out the method is so designed that the milling head (1) has a plurality of adjacent teeth rows arranged at a distance from one another, that furthermore a cutting edge (2) pressed against the cross-sectional contour of the milled inner wall is provided, said cutting edge being fixed on a shield shell (3) extending over the periphery of the inner wall. Furthermore, the shield shell (3) is connected to an advancing device which can be clamped alternately, in cooperation with the shield shell (3), in the pipeline (4). To carry away the waste, a conveying device (6) is finally provided on the side of the shield shell (3) facing the bottom of the pipeline. 2.3. The method now permits a wider range of applications of the milling head, the subsequent advancing of the device or of the shield shell (3) effecting the shearing off of the intermediate webs produced. A considerable increase in output can be achieved by the method. <IMAGE>

Abstract: 2.1 Individual elements of paving stones or lawn grid stones can be pressed into the earth under high load because of their perpendicular contact surfaces. 
<??>In course of time, this leads to irregularities capable of causing accidents and pronounced soil compacting. 
<??>The new basic block elements, preferably produced from recycled plastics, prevent this by means of their oblique contact surfaces. 
<??>2.2 This is achieved by means of a shaping of the basic module which is open on one side, limited by side walls (S1, S, S2), rhomboid in longitudinal section (SF1 + 2) and polygonal and/or arcuate in cross-section. Additional slots, holes or grooves increase the load-bearing capacity and functionality as required. 
<??>2.3 Individual basic modules make it possible, by any combination and interconnection, to obtain a horizontal to a vertical consolidation of high load-bearing capacity of soils, at the same time with a possibility of planting, but also a free-standing, self-supporting space-lattice structure.

Abstract: Cabins for screening magnetic or electromagnetic fields, which cabins contain high-permeability soft-magnetic materials, have until now been constructed as framework structures in which a separation is provided between the magnetic function and the supporting function. The reason for this lies in the existing voltage sensitivity of the high-permeability soft-magnetic materials used. It is provided according to the invention for this separation between the soft-magnetic function and the supporting function to be abandoned. This is possible if the cabins are assembled from sandwich structures, the soft-magnetic material being built into the sandwich structure in a force-fitting manner. In consequence, the soft-magnetic material is mechanically stressed in a defined manner. The advantages lie in a high stiffness of the cabin and in a reduction in the manufacturing costs as a result of material saving and simpler assembly.

Abstract: A logic gate circuit of TTL, ECL or other configuration, having an output stage including at least one transistor (Q2,Q4) and a control transistor (Q3) which switches the output stage to either a low or high conductive state in accordance with an input logic control signal (VIN) supplied to the control transistor (Q3). In order to limit the transient change in potential of the internal voltage supply lines (INT.VCC,INT.GND) of the logic circuit relative to the external voltage supply (VCC(+),EXT.GND) to which they are connected, which occurs during logic state transitions, the base-emitter path of the output transistor (Q2,Q4) is shunted by the collector-emitter path of a current bypass transistor (Q6) the base of which is driven by the control transistor (Q3). The output transistor (Q2,Q4) may be a composite equivalent transistor formed by a Darlington-connected pair of transistors, and the bypass transistor may itself be such a composite transistor. With increasing collector current of the output transistor (Q2,Q4) an increasing proportion of the base drive current supplied thereto by the control transistor (Q3) is diverted by the current bypass transistor (Q6), thereby limiting the maximum collector current of the output transistor (Q2,Q4) and consequently limiting the aforesaid transient change or "bounce" in potential of the internal supply lines (INT.VCC,INT.GND) relative to the external voltage supply.

Abstract: Disclosed is a digital phase-locked loop circuit which provides a control signal for a delay circuit within the feedback path of the phase-locked loop. The circuit has a first series of delay circuits, which have an incremental control signal input, to delay an input clock signal to provide the D input to a D flip flop. The input clock signal is also connected to a second series of delay circuits. The output of this second series is connected to the clock input of the D flip flop. The voltage controlled delay signal input for the second series of delay circuits is supplied by a reference control signal. The output of the D flip flop is passed through a resistor-capacitor filtering circuit and fed back to the first series of delay circuits as the incremental control signal. The delay through the first series of circuits is incrementally larger than the delay through the second, reference, series of delay circuits.

Abstract: A continuous process is disclosed for the acylation or alkylation of aromatic compounds in hydrogen fluoride. The aromatic compound is sufficiently insoluble in hydrogen fluoride that a two phase reaction medium forms. However, surprisingly, the product acylated or alkylated aromatic compound is soluble in hydrogen fluoride. The present invention particularly relates to use of a continuous, multi- stage process for carrying out the acylation or alkylation reaction. In the multi-stage process, the continuous phase can be either the hydrogen-fluoride rich phase or the aromatic compound-rich phase. The movement of the continuous phase relative to the non-continuous (dispersed) phase can be countercurrent or concurrent. The multi-stage process can be operated in a manner such that the aromatic compound feed to the reaction is entirely consumed or such that unreacted aromatic compound is recycled.

Abstract: Data transfers between a workstation bus and a graphics adapter bus are handled by a plurality of first-in-first-out (FIFO) buffers, each of which is independently operable to transfer data in a selected direction between the two buses. The FIFOs are accessible either directly by the workstation processor or by means of a DMA operation. Each FIFO is assigned a unique range of addresses in the address space of the workstation processor to permit a workstation process to transfer a block of data to or from a selected FIFO using a single instruction. Workstation writes (reads) to a FIFO are suspended in response to a first status signal indicating that the high (low) threshold for that FIFO has been reached and are restarted in response to a second status signal indicating that the low (high) threshold has been reached. A buffer counter indicating the amount of data in each FIFO is initialized at zero for outbound transfers from the workstation to the adapter or at the maximum buffer count for inbound transfers from the adapter to the workstation. The buffer count is incremented in response to accesses from the workstation side and is decremented in response to accesses from the adapter side, regardless of the direction of transfer.
