Title: Circuit for connecting and decoupling a two-wire line to the or respectively from the speech and transmission path and the listening and receiving branch of a multiple-wire line
Inventor: PRENOSIL WOLFGANG G
IPC: H04B1/58
Filed: 1983-06-23
Abstract: For this purpose, hybrid circuits are provided which exhibit bridge arrangements which contain two resistors of equal size in each bridge branch. The eight resistors of a bridge arrangement are thus of equal size. The signals to be conducted via the hybrid circuits are conducted via the non-inverting and the inverting inputs of amplifiers belonging together in pairs so that they are present either in the same phase or in opposite phase at certain points of the bridge arrangement or lead away from this via amplifiers. Depending on the object and desired direction of flow of the signals, these are picked up at other diagonal points of the bridge arrangement and supplied to the inverting or non-inverting inputs of one or two operational amplifiers. This results either in an unattenuated or, in the ideal case, no signal at the output of the amplifiers. By means of corresponding circuits connected to the amplifier outputs, the signals are present highly attenuated (infinitely attenuated in the ideal case) or unattenuated at the intended interfaces.

Patent DE-3323931-A1 (DE)
Title: Hydraulic press
Inventor: SCHENK HORST
IPC: B30B9/00
Filed: 1983-07-02
Abstract: The invention relates to a hydraulic press for press-moulding plastic mats reinforced with glass fibres to form mouldings, having a fixed and a movable press traverse as well as a press drive. In order to achieve a drive with a high pressing accuracy during the pressing operation, the movable press traverse (14; 71) is driven by at least one displacement cylinder (15; 72, 73) with a stroke length (17; 75) corresponding to the working stroke (16; 74) of the press (1; 70) and at least two press cylinders (18, 19, 20, 21; 76, 77, 78, 79) of short press stroke (22; 80) which can be coupled to the movable press traverse (14; 71). A very short force flux is thus ensured during the pressing operation within the hydraulic press, tending to reduce the dimensional change of the press and to favour the pressing accuracy. <IMAGE>

Title: Process for producing a coarse granular aggregate for concrete
Inventor: KELLER HERBERT DIPL ING
IPC: C04B18/08
Filed: 1983-07-16
Abstract: In a process for producing a coarse granular aggregate for concrete from fly dust of industrial boiler furnaces, the fly dust is mixed with cement, the mixture is pasted with water, aggregate elements are formed from the pasted mixture and the aggregate elements are hardened. The fly dust and the cement are pasted with the water in a mixing ratio of 10 to 30% by weight of cement and 90 to 70% by weight of fly dust to give moist crumbs. The pasted mixture is formed within a period of at most 120 minutes, using a roller press such as is known per se for the manufacture of so-called nut coal or egg coal from bituminous coals, to give the aggregate elements. The aggregate elements thus formed are hardened, namely by storage in the open while being kept moist, by heat treatment or by steam hardening.

Patent DE-3329533-A1 (DE)
Title: Beaker-type packaging
Inventor: HEYER VOLKER VON
IPC: B65D21/02
Filed: 1983-08-16
Abstract: In the previously known packagings, e.g. for dairy produce, the advertising area of the lid is hidden for the most part when a plurality of packagings are stacked one above the other. The object of the invention was furthermore to design the lid areas of the packagings to be more noticeable. The solution to the problem lies in the oblique position of the lid area relative to the viewer. Stacking of the beakers with an oblique lid area is made possible by an angle in the bottom of the beaker which compensates the difference in height of two beakers located one after the other. The beaker standing above two others does not conceal the lid area of the one standing below or in front of it. Many beakers stacked one above the other form a step-type construction. In plastic beakers made by the thermoforming method, it has previously been impossible to fill one beaker with different contents because one beaker did not have two chambers. Two beakers joined together adjacently were necessary. The solution to the problem lies in the fact that a partition can be inserted through two vertical grooves located opposite one another in parallel on the beaker wall and one groove in the bottom of the beaker.
Patent DE-3334689-A1 (DE)
Title: Device for treating workpieces by means of temperature and pressure surges
Inventor: PFEIFFER EBERHARD DIPL ING
IPC: B23K7/06
Filed: 1983-09-24
Abstract: In the case of a device for treating workpieces by igniting a gas mixture in a workpiece-treatment chamber (22), it is proposed that at least the walls (19, 20) of the treatment chamber (22) be provided with a metal coating (26) whose melting temperature is higher than that of the material of the treatment chamber (22) and whose thermal-conductivity and elasticity values approximately correspond to those of the treatment-chamber material. This coating reduces the wear on those parts of the unit which come into contact with the gas mixture, which wear is caused by the effects of pressure, heat and corrosion during the deburring process. <IMAGE>
Patent DE-3338714-A1 (DE)
Inventor: STAUDIGL RUDOLF DIPL CHEM DR
IPC: C03C13/04
Filed: 1983-10-25
Abstract: The inert or oxidizing auxiliary gases used in the manufacture of optical waveguides often contain traces of water which can be the cause of disruptive OH groups in the glass fiber. According to the invention, this disruption is overcome by reducing the hydroxyl content of optical waveguides by treating the auxiliary gases with heavy water (D2O), so as to replace the hydrogen atom in the OH groups with deuterium, and then subjecting the gases to a drying step. Preferably, the auxiliary gases are subjected to a preliminary drying prior to treatment with D2O.
