Patent DE-3042555-A1 (DE)
Title: Block or seize circuit for telephone exchange selector relay - switches electronically between low and high impedance states
Inventor: ARNDT WOLFGANG DIPL ING
IPC: H04Q3/00
Filed: 1980-11-12
Abstract: The circuit ensures that when - in response to selector relay operation - it has taken on a high resistance value, this condition is maintained until cancelled by operation of an extending circuit in the exchange. The effect of exchange faults can be made less onerous by this means. The circuit has a low impedance path (OK,T1,T2,W1) and a high impedance path (T2,T4,W2). Both connect with the input (c) from the selector. In the ready to select state the low impedance circuit is armed with transistors (T2,T1) in a conducting state. A potential at the input (c) causes the opto coupler (OK) to conduct and a current source (D) and time delay (VZ) to respond. After some 50 milliseconds the delay (VZ) operates and switches over the transistors so that the high impedance circuit is turned on and the low impedance turned off. A flip-flop (FF) latches to maintain this state until an instruction (AREG) to reset (R) is received from the exchange. The further switching of the selector relay causes no change in circuit state.

Patent DE-3102393-A1 (DE)
Title: Slewing apparatus for assembling a bridge
Inventor: RAMBERGER GUENTER DIPL ING DR
IPC: E01D22/00
Filed: 1981-01-24
Abstract: The invention relates to a method and a slewing apparatus for assembling a bridge, in which an old superstructure of the bridge is replaced by a new superstructure by reusing the old abutments and piers. For this purpose, the new superstructure (6) is rotated through 180 DEG  above the old superstructure (3) to be exchanged, that is to say, is brought into position with the deck plate (9) facing down. The old superstructure is subsequently raised and coupled to the new superstructure via the slewing apparatus. The two superstructures are thereafter rotated jointly through 180 DEG  about a longitidunal axis, and the new superstructure is lowered. Finally, the old superstructure is removed. The slewing apparatus possesses two wheels, so-called gyro-wheels, which are connected to the end faces of the superstructures. These gyro-wheels are supported on bearing pedestals (10), the axes of which are located outside superstructures to be rotated. The method and the associated slewing apparatus can be used to particular advantage whenever it is not possible to employ a crane and when the region located underneath the bridge has to be especially protected during assembly, for example because it is densely built-up. The outlay necessary for auxiliary and protective structures is comparatively low and the danger caused by parts crashing down is also limited to a minimum in terms of time.

Title: Double-flow centrifugal mixing pump
Inventor: BURR KARL
IPC: B01F25/64
Filed: 1981-11-14
Abstract: Pump for the mixing, interdissolving and pumping of heterogeneous media, for example for the aeration of effluents in the water purification process or for sucking up and dissolving vapours with heat recovery in the paper-making, textile and chemical industries and in air conditioning, or for sucking up and neutralising flue gases with heat recovery in furnace plants. According to the invention these objects are achieved by a double-flow centrifugal mixing pump, the impeller wheel of which is so designed that two single-flow centrifugal pump impellers, arranged close together and, as it were, back to back on the pump shaft, each with half the number of blades, which are staggered, and twisted more or less relative to one another, are inserted into one another by their blade width at the pump impeller wheel outlet and the cross sections of the successively alternating ducts between the pump impeller wheel blades are designed according to the characteristics of the media to be mixed, as is shown by way of illustration in the drawing, Fig.1 and 2. <IMAGE>
Patent DE-3149843-A1 (DE)
Title: Plunger sealing of a blood sampling device
Inventor: THOMALLA HARRY
IPC: A61B5/15
Filed: 1981-12-16
Abstract: In a plunger sealing of a blood sampling device, a plunger (2) is displaceable in a tube (1), and a bore of the pushed-in plunger (2), which defines a residual volume (14) together with the tube bottom, is sealed. In this arrangement, it is desirable for the plunger seal to provide an improved seal not only relative to the tube but also against the bore, irrespective of tolerances. This is achieved in that the plunger (2) consists of elastic vulcanised silicon rubber in which a stabilising supporting piece (8) is embedded and, at the bore, is designed as a slit-type valve (12). The seal between the plunger and the tube, and the sealing of the bore, are independent of the centering, the tolerances and the position of the plunger, since the latter is sufficiently elastic, because of the selection of the material, always to provide a seal relative to the tube and to form a permanently tightly closing slit-type valve. <IMAGE>

Patent DE-3207093-A1 (DE)
Title: Circuit arrangement for averaging
Inventor: RISCH MATTHIAS R DIPL PHYS DR
IPC: G06F7/544
Filed: 1982-02-27
Abstract: The invention relates to a circuit arrangement for forming an average from measurement values occurring in sequence in time. The circuit arrangement is distinguished by the fact that it automatically forms a compromise, required due to the noise, between short response time and high response threshold, on the one hand, and long response time and low response threshold on the other hand. The compromise is made at the rate of the measurement value sampling, that is to say repeated for each measurement value which is output. According to the invention, this is done by storing a set of last measurement values in time, and obtaining in each case from the last measurement value obtained a control variable which specifies the number of stored measurement values, last in time, from which the averaged measurement value is obtained by addition and division. This arrangement results in a better independence from interference such as, for example, noise. <IMAGE>
