Patent DE-3122858-A1 (DE)
Title: Caravan and sales van with extending side walls
Inventor: MUELLER HORST DR
IPC: B60P3/025
Filed: 1981-06-10
Abstract: This caravan and sales van can be enlarged for living in and selling from by extending the side walls and reduced in size by retracting them for driving. Its housing is composed of three parts, the central part (1) which corresponds to a caravan without side walls, and two side parts (2a, b) which correspond to the halves of a somewhat smaller caravan cut in half along its length. The movement of the side parts takes place by synchronous rotation of four identical threaded rods (6), the left half of which has a left-handed thread and the right half of which has a right-handed thread (or vice versa). They are mounted rotatably in the angular portions of the central part in surrounding strips (3a, b), and run through corresponding counter-threads in the inner surrounding strips of the side parts (4a, b). For the purpose of synchronisation they are connected to one another by driving shafts. The surrounding strips limit the extension and retraction of the side parts, give stability and bear the seals. Pivotable load-bearing arms on the chassis support the side parts from below and relieve the load on the threaded rods. Figure: Section through a caravan housing with side parts extended. <IMAGE>
Patent DE-3124451-A1 (DE)
Title: Process for separating off finely distributed and/or dissolved substances and/or particles from liquids, in particular water, and apparatus for carrying out the process
Inventor: MARQUARDT KURT
IPC: B01D33/00
Filed: 1981-06-22
Abstract: In a process for separating off finely distributed and/or dissolved substances from liquids, a liquid flows in countercurrent through a filter medium which has a higher specific gravity than the liquid. The filter medium loaded with substances filtered out is taken off in the region of the liquid inlet into a filter bed via a transport tube and, using a gaseous medium, is transported into an externally mounted washing column, and from there the cleaned filter medium is returned, via the head, to the filter bed under its own weight. In order, in this case, to have to discharge the wash water only when the fouling of the filter bed makes washing of the filter material and thus the discharge of dirt necessary, the degree of fouling of the filter medium determined is in the region of liquid intake into it and the feed of the gaseous medium effecting the transport of the filter medium is controlled, depending on the degree of fouling of the filter medium, in such a way that the supply of the gaseous medium is reduced or shut off when the threshold value is undershot and gas is fed again when the threshold is exceeded. After throttling or shutting off the gas feed, the washing liquid is admixed either to the filtrate or to the liquid to be treated and separated from this again when the gaseous medium is fed. This makes possible continuous cleaning of the filter medium with discontinuous use of purified liquid.

Title: Ignition device for internal combustion engines
Inventor: BODIG BERND
IPC: F02P3/05
Filed: 1981-06-30
Abstract: An ignition device is proposed which serves to ignite the fuel/air mixture compressed in the cylinder of an internal combustion engine. This ignition device has an ignition coil (6) whose primary winding (5) forms, together with an ignition spark gap (7), a series circuit which can be connected to a DC source (1). The ignition device also has a signal generator (64) which can be driven by the crankshaft of the internal combustion engine and includes a spark gap (68) which is in a current conducting state (a) when the crankshaft rotates by a first angle of rotation and is in the inhibit state (b) when the crankshaft continues to rotate by a second adjoining angle of rotation section. Furthermore, a control memory (33) is provided on which the spark gap (68) brings about in a current conducting state (a) a first load state change (c) and in its inhibit state (b) brings about a second load state change (d). The control memory (33) is monitored by a threshold value switch (19) which, when its threshold value (e) is reached when the second load state change (d) of the control memory (33) takes place, ensures, by switching on, the transferal of the ignition spark gap (7) into the current conducting state and maintains this switching state until the spark gap (68) goes into the current conducting state. The switching threshold (e) of the threshold value switch (19) can be displaced, specifically by a control voltage (h) which is produced as a function of the current conducted across the primary winding (5). In the present case, a temperature-dependent resistor (63) is involved in the second load state change (d) of the control memory (33) in order to avoid misfirings occurring if the internal combustion engine is accelerated too strongly when starting up. <IMAGE>

Title: Drainage unit for Fourdrinier machines
Inventor: BUBIK ALFRED DIPL ING DR
IPC: D21F1/48
Filed: 1981-09-25
Abstract: The drainage unit has a Fourdrinier wire (1) and an additional wire (2) which is taken along a section of the Fourdrinier wire and, with the latter, forms a drainage section (M). In the region of the drainage setion (M), the wires (1 and 2) are taken over a suction box (16) located within the wire loop of the additional wire (2). This suction box is associated with a plurality of deflection elements (25) for the two wires (1 and 2), which elements are provided in the wire loop of the Fourdrinier wire (1) and are arranged in a distribution one behind the other over the opening of the suction box (16) in the direction of running (arrow S) of the two wires (1 and 2). The deflection elements (25) are adjustable transversely to the opening of the suction box (16) and, if appropriate, can be introduced between parallel guide parts (17), provided in the opening of the suction box (16), for the two wires (1 and 2). This results in a simplified wire run and - with an advantageously small deviation from the flat wire track - in particularly intensive drainage of the paper web over a short distance due to individually adjustable surface pressures on the deflection elements (25). <IMAGE>

Title: Method of limiting the welding energy transmitted to the workpiece in ultrasonic plastic welding
Inventor: KLIMES WOLFGANG DIPL ING
IPC: B29C65/00
Filed: 1981-09-28
Abstract: Method of limiting the welding energy transmitted to the workpiece in ultrasonic plastic welding with the aim when welding plastic mouldings of melting only a defined volume in the welding zone and subsequently interrupting further energy supply via the vibratory unit. For this purpose, an electronic circuit forms a value proportional to the mechanical energy delivered by the ultrasonic transducer. If this value exceeds a limit value, the energy supply to the transducer is interrupted and the welding process is ended. The electrical no-load power of the ultrasonic transducer is not registered when forming the energy-proportional value.

Title: Method and arrangement for determining the tension in a rope
Inventor: KAISER PAUL
IPC: G01L5/04
Filed: 1982-02-04
Abstract: The tension in a rope can be determined by a brief deflection being applied to the rope and by the passage of this deflection being detected by two transducers arranged at a distance l from one another, the rope tension F being determined from the time difference  DELTA t according to the equation <IMAGE> where m is the mass of the relevant rope per unit of length. A high measuring accuracy can be achieved with this method, since neither reversal of the force nor clamping to the rope is necessary, because it is possible to use non-contacting transducers. Deflectors, transducers and time-measuring means can be arranged separately or as a constructional unit so as to be adapted to the intended application. <IMAGE>

Title: Scaffold for attachment to roof edges
Inventor: GIESERS HEINRICH
IPC: E04G21/32
Filed: 1982-04-20
Abstract: A scaffold for attachment to roof edges of preferably flat roofs is proposed, in which a plurality of rod-shaped outer supports can be attached in a vertical position to the facade outside the roof in such a way that roofing work is not hindered by the scaffold. The outer supports are hooked onto the facade or the roof edge by means of a hook-on element and supported against the facade underneath the hook-on element. Lying opposite the supporting device is a transverse support which extends roughly horizontally in the use position and has at its end a device for receiving a tensioning rope. The tensioning rope is fixed, on the one hand, to the upper end of the outer support and, on the other hand, underneath the outer support to the facade. A plurality of such outer supports attached at distances from one another are connected to one another by means of scaffolding elements. Opposite outer supports can be connected to one another by means of roof tensioning ropes which are supported, approximately in the centre of the spacing between opposite outer supports, on central supports erected loosely on the roof surface. A sheet and hence a rain protection can be applied in a simple manner to the roof scaffold thus constructed.

Title: Process and apparatus for operating a spinning or twisting machine having a plurality of feed packages
Inventor: WOLF HORST DIPL ING
IPC: D01H13/32
Filed: 1982-04-30
Abstract: The invention relates to processes and apparatuses for operating a spinning or twisting machine having a plurality of feed packages. In these, by means of special constructions and processes, the machine is to be utilised in the most efficient possible way even during non-attendance time. Thus, for example before the commencement of a non-attendance time, the remaining running times of all the feed packages can be determined and the feed packages probably running out in the forthcoming non-attendance time can be indicated for the occasion of the preferred exchange. Another possibility is to determine the remaining running times of all the feed packages and to calculate a reduced machine speed, at which a selectable maximum number of running-out feed packages is not exceeded during the forthcoming non-attendance time. Roving sensors (8), which are connected to each feed bobbin (5), and a running-time computer (7) are used, by way of example, for this. <IMAGE>

Title: Flow-rate measuring device for fluids and modification of the flow-rate measuring device for use as calorimeter
Inventor: STARK REINHARD DIPL ING
IPC: G01K17/16
Filed: 1982-05-25
Abstract: Two ultrasonic transducers (W1, W2) offset with respect to one another in the axial direction of a flow channel are in each case operated alternately in and in opposition to the direction of flow (r) as ultrasonic transmitter/ultrasonic receiver combination for one half period of a square-wave generator (G2). The output signal of the ultrasonic transducer (W1 or W2) in each case effective as receiver, together with the output signal of the ultrasonic oscillator feeding the ultrasonic transducer (W1 or W2) active as transmitter, is fed to the comparison inputs (e1, e2) of a phase comparator (K1). In an evaluating device (A), the output signal of a signal source (S) is multiplied by a flow-rate-proportional signal in the manner of a time division multiplication under the action of a logic section (L) which logically combines the output signals (u3, u4) of the phase comparator (K1) with those of the square-wave generator (G2). In a quantiser (Q), which consists of an integrator (I) and a limit value stage (K2), a pulse train (u8) is generated, the frequency of which is proportional to the product signal (u6). The pulse train (u8) is integrated in an accumulating counting unit (Z). If a constant-voltage or constant-current source is used as signal source (S), the value in the counting unit (Z) corresponds to the flow rate. If, in contrast, the signal source (S) delivers a signal (u DELTA (-)) proportional to the flow/return temperature difference ( theta v- theta R), the value in the counting unit (Z) corresponds to the quantity of heat consumed. <IMAGE>
