Title: Process and apparatus for separating off gaseous contaminants, in particular hydrocarbon compounds, from an airstream
Inventor: SEUS HERBERT
IPC: B01D53/14
Filed: 1984-06-05
Abstract: A process for separating off gaseous contaminants, in particular hydrocarbon compounds from an airstream, is described, in which a droplet-form, vaporous or gaseous carrier medium having a comparatively high dew point in comparison to the contaminants is enriched. The gaseous contaminants accumulate at the carrier medium. The enriched airstream is then cooled beneath the dew point of the carrier medium so that the carrier medium having the contaminants accumulated therein condenses out.

Title: Method for charging accumulators and a device for carrying out the method
Inventor: BAUER JUERGEN DIPL CHEM DR
IPC: H02J7/00
Filed: 1985-08-23
Abstract: A method and the device for carrying out the method for charging accumulators are proposed, in the case of which method the charging current or the charging voltage of an accumulator (12) to be charged is controlled via a regulator (10) as a function of the pressure change per unit time. During the measurement process, the accumulator (12) is closed in a completely sealed manner. If the pressure exceeds a predetermined pressure threshold, then the accumulator (12) is briefly opened by an operating valve (15), and a defined initial position is thus reproduced. In addition to the electrically operating operating valve (15), a mechanically operating safety valve (16) is provided. The method and the associated device make it possible to charge an accumulator quickly and at the same time in a protected manner. The cost of maintenance is reduced by the low electrolyte loss. <IMAGE>

Abstract: The wall (8) of the bellows is provided in such a way that alarm signals are transmitted by an indicating device (21) in the event of wall damage. For this purpose, either an electric conductor (11) is provided in the wall (8) of the bellows, during the interruption of which conductor (11) a signal is produced, or sensors are arranged on the inside of the wall of the bellows, which sensors can be energized upon admission of liquid which has passed through any damaged points, as a result of which alarm signals are likewise produced. Due to these safety devices, damage to the bellows can be quickly noticed, as a result of which machine damage is safely avoided. <IMAGE>

Title: Construction of an electron control device (electrode plate) for flat self-illuminating display devices
Inventor: GSCHWANDTNER ALEXANDER DR PHIL
IPC: H01J17/12
Filed: 1985-12-16
Abstract: Technology of an electron control device which is suitable for controlling gas-discharge displays and for vacuum displays. The electrode planes (Z, S) consist of families of straight solid conductors which are arranged parallel and consist of etched metal sheets. A photographic technique is used on both sides of the metal sheets for the connecting galvano-plastic construction of conductor-track strips. A metal coating, which adheres well, is then electroplated in places. In the further course of the method, trenches are etched in the carrier material and strips of insulation material are then applied onto one of the electrode planes, the two electrode planes are connected and the carrier material is selectively etched to form the galvanic construction, until separate conductor tracks are produced. <IMAGE>

Title: Hydraulic vibration damper with a bypass opening variable as a function of temperature
Inventor: GRUNDEI MANFRED ING GRAD
IPC: F16F9/52
Filed: 1986-02-19
Abstract: The invention relates to a hydraulic vibration damper with a bypass opening, the cross-section of which is variable as a function of temperature, between the working spaces or between a working space and the compensating space. This brings about temperature compensation of the damping forces, which thus remain constant or at least approximately constant over a wide range. The bypass opening with the cross-section variable as a function of temperature is created in a simple manner by means of a closure element with a temperature-dependent action formed by a large-area bimetallic disc which interacts directly with the bypass opening.

Title: Soft gasket material
Inventor: ZERFASS HANS-RAINER DR
IPC: D21H13/42
Filed: 1986-02-25
Abstract: In a soft gasket material in particular for cylinder head gaskets of combustion engines, consisting of a, possibly metal-reinforced, non-woven fabric with asbestos fibres, organic or inorganic synthetic fibres, organic natural fibres and/or metal fibres and usually mineral pulverulent to fine-grained fillers, binders and, if appropriate, further additives, the filler has an average diameter of less than 5  mu m, preferably less than 2  mu m, and a predominantly globular structure, so that the pores of the non-woven fabrics are largely completely filled with filler corresponding to the amount of filler even at small compressions, and the still-open pores are relatively small in volume, with a uniform size and small lateral dispersion. The non-woven fabrics have a high sealing quality, so that their sealing behaviour corresponds to that of a conventionally impregnated gasket, whereas they simultaneously possess the improved deformation behaviour of a non-impregnated gasket. Asbestos-free non-woven fabrics preferably contain between 40 and 80 percent by weight of filler, whereas asbestos non-woven fabrics preferably contain between 20 and 60 percent by weight of filler.

Title: Method for measuring the dampness of bulk materials in the flowing material stream
Inventor: BAUMEISTER KURT DIPL ING
IPC: G01N33/38
Filed: 1986-04-11
Abstract: A method serves for measuring the moisture content of bulk materials in the flowing material stream. In order, in a simple way, to achieve a sufficiently accurate determination of the moisture content of a batch of bulk substances whose dampness varies through the quantity of the batch, the material stream, after dropping freely through a predetermined height, is deflected by an inclined baffle plate (1) and the dampness of the flowing bulk substances (3) is determined continuously or at predetermined equal intervals by means of a measuring sensor (4) located in or above the baffle plate (1). The measurement values are averaged over the discharge time (Figure 2). <IMAGE>

Title: Hydrostatic drive of auxiliary units in a vehicle
Inventor: ALTMANN UWE DIPL ING
IPC: B60T17/02
Filed: 1986-08-21
Abstract: The hydrostatic drive for auxiliary units in a vehicle has two constant-delivery pumps (11, 12) driven by an internal combustion engine (10), one of which pumps pressure medium exclusively to a first load (17), in particular a hydrostatic steering system, via a flow control valve (16). The second pump (12) supplies a first or a second hydraulic motor (23, 25) via a directional control valve (20), depending on the position of the latter, one of these hydraulic motors serving to drive the fan (26) for the radiator (27) of the internal combustion engine and the other (25) serving to drive the air compressor (39) of the brake system. When the compressed-air reservoir (41) of this system is full, the directional control valve (20) and a control valve (45) are set so that the second pump (12) pumps pressure medium only to the second hydraulic motor (23), the speed of which is controlled by means of the control valve. <IMAGE>

Filed: 1987-01-02
Abstract: A leading device for a soil compaction device has a shearing-off beam (3), grinding elements (9, 9', 9'') and a drag beam (7). The grinding elements (9, 9', 9'') are attached to the beam by means of chain links (10, 11, 12).

Title: Thermally triggered shut-off device
Inventor: GOTTFRIED JOSEF DIPL ING
IPC: F16K17/38
Filed: 1987-01-13
Abstract: In the event of a fire, a thermally triggered shut-off device arranged ahead of the regulating valve of a gas-pressure regulator (2) interrupts any further flow of a gas to the consuming unit through the gas-pressure regulator when a certain temperature around the gas-pressure regulator is reached. Coupled with a safety shut-off valve which responds to excess pressure and, if required, lack of pressure, this device represents a very effective additional safety device in the event of fire. A reliable action is achieved by the fact that a spring-loaded valve-closing taper plug (4) is held in a sufficiently open position relative to a valve opening (6) arranged ahead of the regulating valve (5) by a soldered joint (10) that melts when the predetermined closing temperature is reached, and the position of this shut-off device is made visible by an optical indicator (8). <IMAGE>
