Patent DE-3126357-A1 (DE)
Title: Amplifier circuit
Inventor: REINER ROBERT DIPL ING
IPC: H03F1/02
Filed: 1981-07-03
Abstract: The invention relates to an amplifier circuit which consists of the series circuit of an amplification element controlled by the input signal and of an operating element, for example a current source. In this circuit, the output terminal of the amplifier is connected, particularly via a coupling capacitor, to a circuit point between the amplifier element and the operating element. In particular, the amplifier is set in such a manner that it operates in class A mode. It is then the object of the invention to improve the efficiency and the driving (control) range of such an amplifier. This is achieved by designing and controlling the operating element in such a manner that it has a falling current/voltage characteristic in the operating range of the amplifier.

Title: Tool for removing and/or inserting screwdriver blades
Inventor: BAERSCH THOMAS
IPC: B25B23/00
Filed: 1981-07-30
Abstract: Different screwdriver blades used in a pneumatic screwdriver are to be exchanged in a simple manner by means of a tool (1). This object is achieved by a tool (1) whose handle part (2) and base part (4) are connected via a joint (3). At one of its ends, the handle part (2) has a receptacle (5) with a blind hole (6) for pressing in the screwdriver blade, and at its other end it has a fork, formed by extensions (7, 8), for levering out the screwdriver blade. During the latter action, the base part (4), with a supporting part (13) arranged on it, comes to bear on the pneumatic screwdriver. Screwdriver blades can thereby be exchanged quickly and safely without the risk of injury during pneumatic screwdriving. <IMAGE>

Title: Process for preparing aluminium hydroxide
Inventor: GREBER JOERG FRIEDRICH DIPL CH
IPC: C01F7/144
Filed: 1981-08-06
Abstract: The invention relates to a process for preparing aluminium hydroxide, which has the productivity of the European Bayer process of at least 70 kg Al2O3/m<3> lye, but without the previously required classification produces a hydroxide whose fines fraction < 45  mu m is no greater than 10%. The aluminium hydroxide is crystallised from lyes whose molar ratio Na2O : Al2O3 is less than 1.42. For the purpose of preparing the aluminium hydroxide by digestion of bauxite with alkaline additions, followed by removal of the insoluble residue and crystallisation of the aluminium hydroxide with the aid of seed material from the lyes, part of the crystallised hydroxide is redissolved in lye to give a solution highly supersaturated in aluminium, from which a coarse aluminium hydroxide is crystallised out by means of adding seed material. <IMAGE>

Patent DE-3138201-A1 (DE)
Title: People-guiding system
Inventor: ERTLE KARL ING GRAD
IPC: E05F15/614
Filed: 1981-09-25
Abstract: The people-guiding system (I) consists of at least one swing door (1 or 1') and a people-scanning device (40) operating in a contactless manner. If an individual is detected by the people-scanning device (40), the door wing or wings (5) of the people-guiding device (I) open(s) and close(s) after a time interval. Each door wing (5) is driven by a pivoting gear (10) with an electric motor (6) changing the direction of rotation. In order to avoid release of forces which may have harmful effects on the pivoting gear (10) and the electric motor (6) upon arbitrary interruption of the pivoting movement of the door wings (5), a hydraulic coupling (20) is arranged in the power transmission path between the door wing (5) and the electric motor (6), which coupling converts the energy produced on holding the door wing (5) into heat when the electric motor (6) is running. In order to be able to dispense with electromechanical components, the electric motor (6) is controlled via an electronic time relay (50). <IMAGE>
Patent DE-3140107-A1 (DE)
IPC: F04C18/08
Filed: 1981-10-09
Abstract: A parallel and outer axial rotating piston compressor has at least one helical main rotor and a corresponding auxiliary rotor meshing therewith. The main rotor includes a plurality of teeth, the flanks of which are configured as open screw surfaces defined by the screwing of a generating straight line, crossing the screw axis obliquely for each surface. The straight line forms a first inclination angle with a plane disposed perpendicular with the rotary axis of the main rotor. The screw surfaces define a throat screw line. A line tangent to the throat screw line forms a second angle of inclination of the plane. The first inclination angle is smaller than the second inclination angle. The slope of the generating straight line and the slope of the tangent line have opposite signs.

Title: Process for extracting gold from anode sludges
Inventor: IIO TOSHIMASA
IPC: C22B15/00
Filed: 1981-11-12
Abstract: A process for extracting gold from anode sludges originating from electrolytic copper refining is characterised in that the anode sludges are first treated to remove the copper and selenium, then an aqueous suspension of the sludges treated in this way is formed, chlorine gas is fed into said aqueous suspension to dissolve the gold and the gold solution is separated from the residue. This process enables gold to be extracted rapidly, in a simple manner and with a high yield from the anode sludges originating from copper refining, and a very good separation of the other accompanying metals is achieved.

Abstract: The invention relates to a device for closing a plastic-foil pouch or bag or a plastic-foil valve tube of a valve bag, having an anvil (11) and a welding head (10). The object on which the invention is based is to provide a constructively simple welding appliance easy to actuate and maintain and having a low power output for the continuous formation of a welding seam, in which a build-up of foil material in front of the respective welding point and the device part working there is largely avoided, and in which different thicknesses of the foil layers to be joined together or the triple layer of mutually overlapping foil-piece edges are taken into account. For this, according to the invention, the anvil (11) has narrow discs or rings (12) which are arranged parallel to and next to one another and are movable in a resiliently flexible manner and which, as a result of the transverse movement of an adjusting member (27) relative to the discs or rings, individually and successively press the pouch, bag or valve tube (7) counter to spring force against the welding head (10) individually in succession. <IMAGE>

Title: Method and device for measuring and processing signals
Inventor: NEMEC DIETER
IPC: G01R19/00
Filed: 1982-09-30
Abstract: Method and device for measuring and processing signals A method for measuring and processing signals, particularly ignition signals of an internal combustion engine, is proposed in which the ignition signal is converted into a digital signal. By means of an interrupt signal which is generated whenever the signal to be measured reaches a window, and by means of a marking signal which responds to the sequence of interrupt signals, it is achieved that the beginning and the end of a periodic sequence can be established even from disturbed pulse sequences. As a result, it is possible, for example, to digitally detect and further process measurement signals with over- and undershoot characteristics such as, for example, ignition signals. The number of components can be greatly reduced by means of such circuit arrangements and integrated circuits can be used. <IMAGE>
