Title: Circuit arrangement for detecting sequences of identical binary values
Inventor: HECHT WILFRIED DIPL ING
IPC: H03K5/19
Filed: 1982-12-14
Abstract: Central components of the circuit arrangement by means of which, for example, sequences of binary ones are detected in a serial data stream if these sequences exceed a predetermined minimum length counted by bits, are a counter (Z1) and an AND gate (G1). A clock which is mesochronous with respect to the data stream passes through the AND gate (G1) and clocks the counter (Z1) as long as binary ones of the data stream are present at an input terminal (1). When the counter (Z1) reaches the count numerically corresponding to the predetermined minimum length, it outputs a pulse which indicates the presence of a so-called continuous one at an output (A). If a binary zero occurs in the data stream, the counter (Z1) is cleared and the AND gate (G1) is inhibited for the clock. The inhibiting of the AND gate (G1) and the clearing of the counter (Z1) are controlled with the aid of two flip flops (FF1, FF2), three further gates (G2, G3, G4) and an invertor (I1) (Figure 1). <IMAGE>

Filed: 1983-03-22
Abstract: An electrical coil (1) (Fig. 1) has a coil former (2) with side flanges (4 and 5) between which a coil winding (3) is located. The winding ends (6) and the connecting wires (8) which are passed outwards are connected to connecting pins (7). These connecting pins (7) are held in insertion holes (9) in the case of one side flange (4) and are bent around towards the opposite side flange (5) in the final-assembly position. In this case, they engage with their free ends (12) into slots (11) which are open at the edges. At least the winding ends (6) are connected to the connecting pins (7) in a pre-assembly position, where the connecting pins (7) project freely radially. Subsequently, the connecting pins (7) are bent around and are then connected to connecting wires (8). The attachment of the winding ends (6) to the freely projecting connecting pins (7) results in advantages from the production-engineering point of view. In the final-assembly position, the connecting pins (7) are fixed well. Lug-shaped connecting pins (7a), having plug-in or clamping connections, can also be provided instead of the connecting pins (7).   <IMAGE>

Patent DE-3317786-A1 (DE)
Title: Device for guiding and deflecting rapidly moving rolled rod
Inventor: WORGT WALTER DIPL ING
IPC: B21B39/14
Filed: 1983-05-16
Abstract: The invention relates to a device for guiding and deflecting rapidly moving rolled rod in high-duty rod-rolling mills as it emerges from the last pass of a rod rolling block, passes through a downstream cooling section and is deposited in non-concentric loops on a moving conveyor by a loop layer arranged obliquely to the rolling line. At rod speeds of 50 m/s and above, abrupt deflection of the rod in the bent, double-walled guides ahead of the loop layer often lead to damage. The aim and object of the invention is, by appropriate arrangement, to change the shape of the guide and deflection tube in such a way that points of discontinuity are avoided, with the result that a build-up of the rolled rod is avoided even at very high speeds. The object is achieved according to the invention by the fact that a guide tube 1 supported in a plurality of holders 7, 8, 9 and 10 and bent in accordance with the elastic neutral axis is arranged within a cooling trough 4 between the cooling section 12 and the loop layer 15. <IMAGE>

Title: Roadway joints
Inventor: STOG WILHELM DIPL ING
IPC: E01D19/06
Filed: 1983-06-28
Abstract: In roadway joints with a joint strip made in particular of neoprene, a symmetrical subconstruction can be used in that, with great edge stability and maintaining a central strip, zones are provided in the joint strip, in which zones deformations can arise in such a manner that they have no or virtually no influence on in particular the upper side of the joint strip. To this end, both on the upper side and on the lower side, obliquely running notches are designed, which have rounded edges and in each case, seen from the upper and lower side, correspond purposively with one another in such a manner that they run towards one another in an arrow-shaped manner and overlap one another on the end side. For optimum edge stability, a number of embodiments of metal profiles are proposed. <IMAGE>

Title: Asynchronous machine with a double-cage armature winding
Inventor: MEYER ARMIN DIPL ING DR
IPC: H02K17/18
Filed: 1983-07-08
Abstract: The double-cage armature winding for an asynchronous machine has lower (4) and upper rods (3), which are located directly one above the other, in a common groove (1) with a rectangular profile. The material of the upper rods has a higher electrical resistivity than that of the lower rod. The upper and lower rods are connected at the ends to a common short-circuiting ring (6). Alternatively, the upper rod and lower rod consist of a composite material having a different electrical conductivity. The new cage winding combines the advantages of a high-rod winding with a double-cage winding. <IMAGE>

Title: Plant and process for generating synthesis gas from coal, using thermal energy generated by nuclear means
Inventor: ARNDT ERHARD ING GRAD
IPC: C10J3/16
Filed: 1983-09-30
Abstract: The invention relates to a plant for generating synthesis gas from coal, using thermal energy produced in a high-temperature reactor, in which the helium-operated intermediate circuit usually used is omitted. The steam gasifier, in which the coal is converted by feeding process heat and process steam into synthesis gas, is heated not by nuclear heat, but exclusively by conventional means, and the steam superheater providing the process steam and a steam generator are arranged in the helium circuit of the high-temperature reactor and accommodated within the reactor pressure vessel. Due to the omission of the components of the intermediate coolant circuit, considerable savings are achieved; moreover, the exit temperature of the helium can be lowered by more than 100 DEG C.

Title: Process for the production of basic soaps
Inventor: KADLCIK IVAN DIPL ING
IPC: C11D13/00
Filed: 1984-01-12
Abstract: To avoid the use of sodium chloride in soap boiling processes an excess of sodium hydroxide solution is used in the production of basic soaps and is neutralised in the final process step by phosphoric acid and/or in mixtures with other inorganic or organic acids predominantly to disodium hydrogen, monosodium dihydrogen and/or trisodium phosphate. It is also possible by simultaneous admixture of sodium hydroxide solution to aim at an increased content of phosphates. It is possible to use for this conventional soap kettles or continuous saponification systems, possibly supplemented by a stirred kettle or a metering, mixing and holdup device. The excess sodium hydroxide solution is deposited as acid soap from the lower phases by fatty acids or fats. In the case of fatty acid saponification, the resulting waste water is only slightly contaminated and can be recirculated, and in the case of neutral saponification an almost pure aqueous solution of glycerol results. Owing to the omission of the highly corrosive sodium chloride, it is possible for all the apparatus to be constructed of simple or low-alloy steels, and the production of a sodium chloride solution can be dispensed with. Owing to the phosphate content in the finished soaps, the addition of complexing agents for heavy metals can be omitted.

Title: Integrating small-signal input circuit
Inventor: MAIO KENJI
IPC: G06G7/186
Filed: 1984-02-08
Abstract: This circuit exhibits a Miller integrator (30) which is capable of cyclically carrying out the integration process, the resetting process and the process for compensating for the input offset current, and exhibits an input offset current compensation circuit (40) which forms a feedback circuit of the amplifier (9) in the Miller integrator (30) so that, during the compensation process, the amplifier is supplied with a compensation current for compensating for the input offset current and during the integration process, the stored compensation current is supplied to the amplifier. During the compensation period, a low-pass filter (50), which blocks off sinusoidal components in the input signal, is connected to the input of the integrator so that the compensation holding current is not influenced by noise components. <IMAGE>

Title: Shaped casing pieces for a chimney
Inventor: AUGUSTIN LOTHAR
IPC: E04F17/02
Filed: 1984-02-17
Abstract: In the case of three-layered house chimneys which are formed from shaped casing pieces in which an inner pipe is inserted, problems may be expected if the inner pipe is not sufficiently insulated from the shaped casing pieces. Up until now, insulating mats have been pushed in in order to provide an insulation between the inner pipe and the shaped casing pieces. The insulating mats can no longer fulfil their purpose, however, if they become moist, which is always the case, in particular at low chimney temperatures, and are destroyed by the resulting sulphuric or sulphurous acid. To remedy this, the invention proposes to arrange the insulating mats at a distance from the outer wall of the inner pipe, so that ducts running along the inner pipe are produced, and to bring these ducts into connection with the outside air, by way of openings in the lower chimney region and an upper-side opening, with the result that, when the chimney is operating, a constant air movement which is guided upwards and which reliably keeps moisture away from the insulating mats is achieved. <IMAGE>
