Patent DE-3235832-A1 (DE)
Title: Use of a gold-coloured copper alloy for the production of fittings and the like
Inventor: PRINZ BRUNO DIPL ING DR
IPC: C22C9/06
Filed: 1982-09-28
Abstract: The attempts to date to imitate the shades of gold and of its alloys by means of alloys of less precious metals have been unsuccessful in particular because the materials did not have sufficient resistance to tarnishing. For the production of articles such as fittings, watch cases, mountings, jewellery, cutlery, cups and the like, it is now proposed to use a copper alloy with 4 to 6% of nickel and 4 to 6% of aluminium, the remainder being copper and including unavoidable impurities arising from the production. The alloy should preferably also contain 0.5 to 1.8% of iron and/or 0.3 to 1.5% of manganese.

Title: Warping and beaming machine
Inventor: WIEDENFELD HELMUT
IPC: D02H7/00
Filed: 1982-10-13
Abstract: The alignment of the warp beam (18) with the outer edge (22) of the roll (17) located on the warping drum (16) is made possible with high accuracy and speeded up by an alignment device (23). The alignment device (23) can, for example, have a pivotable arm (25), to which is fastened a rod-shaped element (29) carrying an adjustable pointer (27). The arm (25) can be extended if appropriate, and the pointer (27) is first set to the outer edge (22) of the roll (17). After the arm (25) is pivoted in the direction of the warp beam (18), the warp-beam disc (20) can be aligned according to the pointer (27). By means of a further pointer, the other outer edge of the roll (17) can also be sensed for the purpose of also aligning the other warp-beam disc. <IMAGE>

Patent DE-3307116-A1 (DE)
Title: Installation for aeration and temperature control of living and/or working rooms
IPC: F24F3/052
Filed: 1983-03-01
Abstract: The installation works with variable air flow. In a large part of the regulation range, the room temperature is kept constant in that air is increasingly throttled from a cold channel system (3, 3a) to air outlets (6, 7, 8), when the quantity of heat to be carried off decreases. Before reaching the hygienic minimum air rate, relatively warm air with higher pressure is introduced from a warm channel system (4, 4a) into the air outlets, for which purpose, after a predetermined throttling of the overall flow, closure and throttling members (56) on the air outlets (6, 7, 8) are opened. The advantage results that it is possible to work with as small an air flow as possible and, in the event of the need for a return of heat to the room (10), inexpensive heat can be used. <IMAGE>
Patent DE-3310010-A1 (DE)
Title: Reactive-power-compensated rotating-field machine
Inventor: BRYCHTA PETER DIPL ING
IPC: H02J3/18
Filed: 1983-03-19
Abstract: In the case of rotating-field machines which are used in underground mining and tunnel construction, voltage remains on the secondary side of the main contactor contacts for a relatively long time, in the case of a driven motor shaft, when the reactive-power-compensated motor is switched off via the main contactor or when the motor protection trips at the connecting points. This is avoided, and rapid voltage-free switching of reactive-power-compensated rotating-field machines is hence achieved, in that the compensation capacitors of the rotating-field machines have short-circuit units allocated to them which can be driven via a drive and measurement processing unit. In this case, the measurement processing unit is connected in voltage terms to the motor phase windings and in measurement terms to one of the phases so that, in voltage terms, an intrinsic supply is provided. In addition, the drive unit, which is connected downstream of the measurement processing unit, is connected on the one hand to the short-circuit units and on the other hand to a switch which is allocated to the temperature-monitoring unit. Tripping of this switch results in the control line of the temperature-monitoring unit being interrupted, and hence switch-on locking of the rotating-field machine is achieved during the voltage-free switching.

IPC: G06F11/20
Filed: 1983-03-29
Abstract: An integrated dynamic write-read memory includes at least one redundant row and/or column initially excluded from normal operation of the memory but available for normal operation as a replacement. At least one row decoder is connected to the memory matrix and at least one column decoder is connected to the memory matrix for addressing. A column address pulse is fed to the memory matrix for initiating addressing by matrix columns and a row address pulse is fed to the memory matrix for initiating addressing by matrix rows. A normal data path leading out of the memory matrix includes a tristate output connected to the normal data path and actuated by addressing with the stored digital data. Another decoder is connected in the normal data path between the memory matrix and the tristate output with an output connected to the tristate output. The other decoder blocks the normal data path from the memory matrix to the tristate output upon addressing each row or column of the portion of the memory matrix intended for normal operation replaced by a redundant row or column and upon simultaneous external activation of the other decoder. The other decoder also indicates the insertion of a redundant row or column in place of a row or column in the portion of the memory matrix intended for normal operation with the appearance of a uniform indicating signal at the data output.
Patent DE-3311600-A1 (DE)
Title: Stand
IPC: F16M11/38
Filed: 1983-03-30
Abstract: The invention relates to a stand (1), in which a stand pipe can be moved with respect to a foot part (3) or a supporting part (28) of a foot part (3) in the vertical direction, and this movement is used for driving a drive connection between the stand pipe (2) and at least three stand feet (4, 5, 6), the stand feet (4, 5, 6) being moved from a folded-together transportation position into an in-use position having approximately horizontal stand feet. In one preferred embodiment, a carrying part (29), on which the stand feet (4, 5, 6) are supported such that they can move in rotation and which is connected to the stand pipe (2), engages around a supporting part (28). In the region of the pivoting axes, the stand feet (4, 5, 6) carry toothed segments (13) which interact with toothed rods on the supporting part (28). In the event of a downwards movement of the stand pipe (2), the stand feet (4, 5, 6) are then moved from a folded-upwards transportation position into a horizontal position. The supporting part (28) and the carrying part (29) are pretensioned with respect to one another with the aid of a restoring spring (35), so that the folded-up transportation position is held by the restoring spring (35) and, in the in-use position, the carrying part (29) is locked against the supporting part (28) with the aid of a latching device (27). In order to erect the stand, it is necessary only to press on the standpipe (2), and the latching device (27) only has to be unlocked for dismantling. <IMAGE>
Patent DE-3316289-A1 (DE)
Inventor: KARK UWE
IPC: F16D1/08
Filed: 1983-05-04
Abstract: An arrangement for fastening a roll ring (5) to an overhung roll shaft (1) by means of a taper sleeve (8) which transmits essentially the entire torque and which is loaded axially by a spring (43) supported on an abutment (47) adjustable on the free end of the roll shaft. The roll ring can be exchanged easily because of a cylinder part (21) arranged radially within the spring. This cylinder part forms a first annular cylinder space (40) for prestressing the spring, with which it interacts via a flange, and a second cylinder space (22) for drawing off the taper sleeve, to which it is connected via engagement means (28). The spring and the hydraulic devices can remain in place when a roll ring is assembled and removed, because their outside diameter is less than the bore of the roll ring.

Abstract: In this process for recovering noble metals of group VIII from a contaminated catalyst solution originating from the carbonylation of methyl acetate and/or dimethylether (the catalyst solution containing carbonyl complexes of these noble metals, organic or inorganic promoters, undistillable organic contaminants as well as volatiles) the volatiles are distillatively removed from the catalyst solution and the remaining distillation residue is water-treated, whereby the noble metal/carbonyl-complex is precipitated together with the organic contaminants and is separated from the aqueous phase, while the promotor is dissolved and recovered in conventional manner. The noble metals are then set free in elemental form by subjecting the noble metal/carbonyl-complex separated and contaminated with organic polymers at temperatures of 150 DEG  to 300 DEG  C. to treatment with an ethyleneglycoldialkylether solvent of the formula R(-OCH2-CH2)n-OR, in which n stands for a number of from 1 to 4 and R stands for identical or different alkyl groups having from 1 to 6 carbon atoms. The noble metal can then be recovered by filtration, and the solvent can be freed of organic contaminants by distillation.

Title: Length-measuring device, in particular for measuring parallel end measures
Inventor: REIMANN GERHARD DIPL ING
IPC: G01B5/02
Filed: 1983-08-27
Abstract: A length-measuring device is provided, in particular for measuring parallel end measures. The aim of the invention is to enhance the use-value characteristics of such a length-measuring device and to lower its production costs. The invention achieves the object of providing a length-measuring device in which the influence of arrangements of functional elements which cause faults is reduced. Essential features of the invention are the coincidence of the measuring plane (16) and the guide plane of the measurement carriage (2), in which two displacement sensors (19, 20) are arranged in a flush and adjustable fashion. With the aid of the resilient means (6), the elongated measurement carriage (2) is guided without play between the guide tracks (3, 4), and can be clamped in the guide plane without constraint. The displacement sensor (19) can be finely adjusted into the measurement carriage (2) by means of a reducing adjusting system (17) whose actuating elements (30, 31) are preceded by a further reducing means (35). The prescribed measuring points on the end measures can be touched quickly and reliably with the aid of a sliding device (41) whose sliding and pivoting range is delimited by the stops (44, 52, 53). <IMAGE>

Title: Process for controlling the ventilation of and air extraction from rooms and buildings in which work is performed with radioactive and/or toxic materials
Inventor: BRENDER ROLAND
IPC: G21C13/02
Filed: 1983-10-04
Abstract: In the control processes hitherto for the ventilation of and air extraction from rooms and buildings in which work is performed with radioactive and/or toxic materials, large quantities of air are required, which is expensive in terms of energy and leads to large quantities of special waste from the accumulation of used filters. A remedy is provided by a reduced air volume flow, in that the actual values of the room temperature, the radioactivity or the pollutant concentration and the pressure difference at the filter are compared with reference values and the air supply and removal are correspondingly adjusted by the actuation of control elements when deviations from the reference values occur.

Title: Device for clamping the abrasive-material carrier onto, or releasing it from, the oscillating plate of a portable oscillating grinding machine
Inventor: BRAUN ROLAND DIPL ING
IPC: B24B23/04
Filed: 1984-02-04
Abstract: The subject of the invention is a device for clamping the abrasive-material carrier onto, and releasing it from, the oscillating plate of a portable oscillating grinding machine. The said device comprises an L-shaped piece of wire which is pivotably guided in two mountings attached on the oscillating plate, one situated at a distance behind the other transversely with respect to the longitudinal axis of said oscillating plate. The longitudinal arm, which is used as an actuating lever, of the piece of L-shaped wire can be locked in a holder provided on the oscillating plate. The object of the invention is to provide a device for clamping the abrasive-material carrier of portable oscillating grinding machines which is comparatively simple and cost-effective. According to the invention, this object is achieved in that the mounting, arranged on the side of the longitudinal arm (2), is embodied by a radial guide (7, 15) which receives a correspondingly shaped bent-out section (10, 16) of the longitudinal arm, and in that the mounting, opposite the radial guide, is designed as a pivoting holder (12, 18) for the bent-around end of the transverse arm. <IMAGE>

Title: Method and device for testing the tightness of valves
Inventor: DUNGS KARL
IPC: G01M3/28
Filed: 1984-03-13
Abstract: In order to test the tightness of the valves (2, 3) in controlled systems for gaseous media, in particular for gas-fired plants, the pressure in a line section (4) connecting the valves (2, 3) is (slowly) increased by means of a pump (8) which has a specific low conveying capacity determined by an upstream restrictor (10). In the case of tight valves, the pressure in the line section (4) reaches a predetermined value. When this value is reached, a pressure monitor (7) connected to the line section (4) generates a signal which indicates the tightness of the valves. If, however, the pressure is not reached, and there is therefore no signal from the pressure monitor (7) a signal is generated which indicates a fault. This signal which indicates a fault can, for example, block the burner of a gas-fired plant. The device for carrying out the tightness testing method can be formed as a compact basic unit by combining the pump (8) with restrictor (10), the pressure monitor (7) and a valve (9) which shuts off the pump line. <IMAGE>

Filed: 1984-06-12
Abstract: Circuit arrangement for suppressing periodic noise signals in danger alarm systems. In parallel with the conventional signal processing chain of an alarm system, a PLL circuit (7) is used which transmits a signal if a periodic noise signal is present at the output of the amplifier chain (1-5). This signal of the PLL circuit (7) is combined with the output of the amplifier chain (1-5) via a logical AND circuit (9). If a periodic noise signal is present at the input of the amplifier chain (1-5), the emission of the alarm is thereby suppressed and a fault message is transmitted to the central alarm unit. <IMAGE>
