Title: Thermal insulation for pipelines, valves and the like, especially for nuclear installations
IPC: F16L59/02
Filed: 1982-02-19
Abstract: The invention relates to thermal insulation for pipelines, consisting of shell-shaped elements, which can be assembled in modular form, the shell-shaped elements in each case consisting of thermal insulation material which is surrounded on all sides by a metal jacket. The object of the invention is to provide the maximum possible shape stability of the elements of such thermal insulation, to be precise without using rigid insulating material and minimising thermal bridges. In order to achieve this object, the invention proposes that the elements in each case have a supporting structure, which surrounds the insulating material (90), consists of annular disc segments (10, 20) arranged on the ends and profiled bars (30, 40, 50) running in the longitudinal edges, and on which the metal jacket is mounted, which metal jacket can consist to the greatest possible extent of very thin metal foil, because of the supporting function of the supporting structure. The end sides and the longitudinal edges of the elements are preferably constructed in a stepped manner. <IMAGE>

Title: Circuit arrangement for increasing the ignition current in a brushless rotating welding machine
Inventor: HABELER HEINZ DIPL ING
IPC: B23K9/067
Filed: 1982-05-21
Abstract: The circuit arrangement is provided for the energising machine of a brushless rotating welding machine, each of the two DC voltage terminals of the bridge rectifier being connected to the inverting welding current socket, and a capacitor which is arranged in series with the field winding of the energising machine being looped into one of the two connecting lines. Connected in reverse-parallel with this capacitor are two diodes, one of which is arranged in the charging circuit and the other in the discharging circuit of this capacitor, and, furthermore, a resistor is connected downstream of the diode which is arranged in the charging circuit. This circuit results in a high effective ignition current, as a result of which porosity now no longer forms at the point where the welded seam is applied when using electrode types having a material transfer which is very viscous or forms large drops.

Title: Control arrangement for pulse-controlled field-effect transistors
Inventor: RJOSK HEINZ ING GRAD
IPC: H03K17/691
Filed: 1982-08-10
Abstract: An attenuating resistor located in the gate circuit is connected to these field-effect transistors. To switch on slowly and then switch through rapidly and to reduce the switching losses, it is proposed that a choke (5) is connected in front of the attenuating resistor (4), the inductance of which choke, together with the capacitance (6) - which may be expandable by external circuit means - of the gate-source path (GS) of the field-effect transistor (1), forms a resonant turn-on circuit. The result is that the voltage across the gate-source path can reach its peak within one period, the capacitance of the gate-source path is almost fully charged and then recharged for the energy content of the choke. <IMAGE>

Title: Fork arm for lift trucks
Inventor: VETTER KLAUS
IPC: B66F9/12
Filed: 1982-12-03
Abstract: Fork arms for lift trucks consist of a supporting arm for receiving the load and a suspension part which is arranged thereon essentially at right angles and has fork hooks for fastening the fork arm to a supporting plate of the lift truck. In the known fork arms, the fork hooks are as a rule welded or forged to the fork arm or are detachably arranged on the fork arm by push-in pin connections or screwed connections. Disadvantageous in these known constructions are the costly manufacturing processes, restrictions in the choice of material, a lack of interchangeability and possibly high repair costs as well as the requisite use of specially trained personnel in the event of any repairs. According to the invention, at least one essentially horizontal groove is arranged in the suspension part of the fork arm, and the fork hook is provided with a web, the groove and web being designed with a positive-locking and frictional cross-sectional profile in the loading directions of the fork arm. The disadvantages of the known constructions are avoided, since there is a free choice of material and the manufacturing process as well as the assembly are simple.

Title: Method for monitoring a photographic treatment bath and associated dosing device
Inventor: KRUPS ROBERT KARL ERNST ING GR
IPC: G03D3/06
Filed: 1982-12-08
Abstract: In the monitoring of a photographic treatment bath, during which a dose of replenisher liquid matched to the expected consumption is fed to the bath for each charge of photographic film-base material to be treated, the aim is to ensure that the bath is kept continually as close as possible to its setpoint values, in particular to its setpoint concentration. For this purpose, it is provided according to the invention that in addition to the feeding of a bath dose per charge the bath concentration is monitored by measuring the bath density and is regulated to maintain a specific setpoint value. In addition, the dose to be fed per charge is dimensioned as a function of the area and of the total exposure of the next charge to be treated and fed by means of a particularly precise, digitally controlled dosing device. <IMAGE>
Patent DE-3245573-A1 (DE)
Inventor: BAUS HEINZ GEORG
IPC: E06B3/964
Filed: 1982-12-09
Abstract: The invention relates to a frame, more particularly for a shower partition, the said frame comprising at least two shaped or profiled rails preferably connected together at a right angle. In the case of a frame of this kind, problems arise in the corner area in that the surfaces of the profiled rail, shaping element, covering profile, or the like in that area must be carried over into each other. Moreover, as a result of assembly inaccuracies, when a frame of this kind is assembled, gaps arise into which dirt can penetrate and which are also constructionally undesirable. It is therefore proposed, according to the invention, that a facing element (16) be arranged in the connecting area between the profiled rails (2, 4) on the outside of the frame, the said facing element comprising at least one spring locking means (36, 58). This spring locking means engages and/or catches in an opening (30, 36) in the profiled rail (4), thus ensuring an easily produced but functionally reliable attachment of the said facing element (16) to the profiled rail (4).

Title: Wire rope
IPC: B65H69/06
Filed: 1982-12-10
Abstract: In order to lengthen by splicing a wire rope having a ply of strands (2) possessing a multiplicity of wire plies (5; 6; 7; 8), the strands (2) have under their outer wire ply (8) a core strand (3) with a smoothed surface. They can then be spliced by abutting the wires of the outer wire ply (7) of the core strand (3) and the wires of the outer wire ply (8) of the strands (2). The strands (2), possessing under their outer wire ply (8) a core strand (3) with a surface smoothed, for example, by drawing or rolling, are equivalent in the rope to the parallel-lay strands which are customary for large strand diameters, but which could be spliced only with one wire ply, namely the outer, with a correspondingly high loss of strength. <IMAGE>

Title: Device for removing cooling water from the surface of strips and metal sheets
Inventor: KERSTING EMIL FRIEDRICH
IPC: B21B45/02
Filed: 1983-03-15
Abstract: The present invention relates to a device for removing cooling water from the surface of strips and metal sheets running through. The removal of the cooling water which does not flow off spontaneously and remains on the surface of the strip or sheet is problematic particularly in the case of very wide sheets. Blowing it away or flushing it away has proved inadequate, particularly in the case of wide strips or sheets. To achieve the object of allowing water removal without the risk of compromising the continuous application of water, the invention proposes to provide at least one brush (5), which rotates in the opposite direction to the direction of transport of the strip or sheet (3), extends over the entire width of the material to be cooled and can be adjusted relative to the surface of the said material. <IMAGE>

Title: Process and device for cladding a pipe with a prefabricated tube of elastically extensible foam
Inventor: BAEUSER MARTIN DIPL PHYS DR
IPC: B29C63/20
Filed: 1983-03-29
Abstract: The invention relates to a process and a device for cladding a long pipe with a prefabricated tube of elastically extensible foam. In order to aid the axial sliding of the tube onto the pipe an overpressure is generated between tube and pipe during the axial displacement by an air current flowing first through the interior of the pipe in a direction opposite to the slide direction of the tube and subsequently being deflected into the slide direction. So that the sealing of the free end of the tube can be dispensed with, according to the invention the deflected air stream - seen in the direction of sliding - is introduced between the tube and pipe directly after the point of contact of the pipe end directed towards the tube (Fig. 2). <IMAGE>

Title: Pressure filter, in particular drum filter, for continuous superatmospheric pressure filtration of solids from a pulp
Inventor: KELLERWESSEL HANS DR
IPC: B01D33/00
Filed: 1983-06-15
Abstract: The invention relates to a pressure filter, in particular a drum filter, for continuous superatmospheric pressure filtration of solids from a pulp, having a shaft which is connected to the pressure chamber, receives the filter cake material and has a discharge orifice for pressure-tight ejection of the filter cake material into the surroundings at atmospheric pressure. The pressure filter is characterised by a mechanical compression element (15) which compresses the filter cake material (7) situated in the shaft (10) before outlet from the discharge orifice. This compression advantageously results in the filter cake material (7) lying tightly against the shaft wall and thus reliably sealing off the pressure chamber (2) from the surroundings at atmospheric pressure. As a result, other sealing components, required in previously known pressure filters for pressure sealing, are advantageously dispensed with, which components, particularly in the case of abrasive filter cake material, do not ensure reliable permanently pressure-tight ejection of the filter cake material in the known pressure filters. <IMAGE>

Title: Dispensing device for food and/or beverages
Inventor: WOLTERMANN ERICH DIPL ING
IPC: B67D3/00
Filed: 1983-08-18
Abstract: A dispensing device (10) for beverages is equipped, near its dispensing switch (12), with a transmitter/receiver unit (11). The transmitter/receiver unit (11) is switched on by actuation of the dispensing switch (12). Each waiter authorised to dispense drinks wears, preferably on his wrist, a mini-transmitter (13). The mini-transmitters (13) for the various waiters are equipped with different transmitting frequencies.   The mini-transmitter (13) brought near to the transmitter/receiver unit (11) is switched on by the activated transmitter/receiver unit (11), after which its transmitting frequency is sensed by the transmitter/receiver unit (11). A signal is sent out from the transmitter/receiver unit (11), which signal activates a counter and control device (14) in such a way that a counter assigned to the transmitting frequency of the particular mini-transmitter (13) is first actuated and the dispensing of the required beverage is then initiated. This ensures that a satisfactory control of the quantities of beverages removed by the individual waiters is obtained. <IMAGE>

Title: Device for generating pulses in drives for storage devices
Inventor: HEIDE JOHANN VON DER DIPL ING
IPC: G11B15/18
Filed: 1983-09-02
Abstract: Drive arrangement for storage media having a drive motor and a device for generating pulses at a frequency which is proportional to the speed of the motor, having a generator which, during operation, generates for each revolution of the rotating component at least one signal pulse which alternates once between two polarities, and having an evaluation circuit, to which these alternating signal pulses are applied in order to generate the pulses at its output. The evaluation circuit has a comparator with asymmetric hysteresis which is provided with two inputs and one output, between the two inputs of which the output signal of the generator is present and the hysteresis of which is matched with the generator output signal in such a way that the comparator output changes over from a first potential to a second potential if the amplitude of the signal pulse with predetermined polarity exceeds a predetermined switching voltage value, and changes back from the second potential to the first potential when the signal pulse passes through its zero crossing from the predetermined polarity to the opposite polarity. <IMAGE>

Title: Cover sheath for the steering rod/steering column connecting area, in particular for cycles, motorcycles and the like
Inventor: NASTRUCCI GIANFRANCO
IPC: B62K21/18
Filed: 1983-09-28
Abstract: The invention relates to a cover sheath for the steering rod/steering column connecting area, in particular for cycles, motorcycles and the like, this connection being produced by simply welding two metal elements after previously chrome-plating the same, that is to say without using the conventional connecting element made of metal which is referred to as a "pipe". The problem on which the invention is based consists in covering the steering rod/steering column connecting area economically and with aesthetic advantages in order to reduce and/or to cover the damage caused at this point by oxidation. This problem is achieved in that a cover sheath made of thermoplastic material is used which consists of a partially elastically deformable body which is expediently of hollow construction so that it can be pushed onto the steering rod/steering column connecting area with a simple and rapid procedure.

Title: Hollow body which is subjected to internal pressure stresses and/or temperature stresses
Inventor: MOSKAU GERHARD ING GRAD
IPC: F16L9/10
Filed: 1983-09-28
Abstract: A hollow body which is subjected to internal pressure stresses and/or temperature stresses is produced from material having a low tensile strength, its outer surface being constructed to be concave in a multiple manner. Its depressions run longitudinally or at right angles to its longitudinal direction or as required, in any desired directions. At least the points of the projections on the outer surface can be held by a material having a higher tensile strength. In consequence, cheaper materials can be used, or expensive materials can be utilised better. Good heat insulation and good heat conduction are possible so that the hollow body according to the invention can be used advantageously for heat or cold transportation lines, ceramic motors, pressure reactors, furnaces, heat exchangers, solid-object transportation lines where a large amount of frictional heat is developed, machine shaft bearings or similar applications.
