Title: Multi-layered chimney
Inventor: KRAUSS PETER DIPL ING
IPC: E04F17/02
Filed: 1984-03-05
Abstract: The invention relates to a multi-layered chimney having at least one waste-gas-channelling inner pipe, having an upper covering which exhibits an opening adapted to the inner cross-section of the inner pipe, having a heat-insulating layer enclosing the inner pipe, having a surrounding casing supporting said layer on the outside, and having at least one aeration duct, between the inner pipe and the surrounding casing, which extends continuously approximately over the entire height of the chimney, is delimited by the outer side of the heat-insulating layer and, in the lower region of the chimney, is open to the chimney surroundings, in particular to the heating chamber. The invention aims to design the chimney in such a manner that improved air flow takes place in the aeration ducts, the invention being for the aeration duct to be protected from rainwater or dripping water. This is achieved in that the aeration duct (5) is connected, in the region of the chimney head (8), via an annular gap (22) to the free cross-section (25) of the inner pipe (2), the gap of which extends transversely with respect to the vertical, being internally delimited by a downwardly extending annular projection (19) on the cover side and being externally delimited by an upwardly directed annular projection (21) on the side of the inner pipe. <IMAGE>

Title: Hose attachment having an externally cylindrical hose connecting stub, which is integrated with a housing, and a spring clamp
Inventor: HORN KURT
IPC: F16L37/00
Filed: 1984-10-09
Abstract: The invention relates to a hose attachment having a sleeve-shaped spring clamp for attaching and securing an overpressure hose against pulling off and breaking off at a connecting stub, without a hose mandrel profile. The externally cylindrical hose connecting stub, having the plugged-on hose, is surrounded by a hollow-cylindrical protective collar which is integrated with a housing and has a longitudinal slot and on which at least one radially inwardly bent trapezoidal tongue of the spring clamp is attached in the form of a claw. In addition, offset circumferentially with respect to the tongue or tongues, the spring clamp has at least two compression webs on its end facing away from the housing, which compression webs project radially inwards such that they rest on the hose in a prestressed manner and fix it axially. The two circumferential spring ends of the sleeve-shaped spring clamp are bent such that they overlap in such a manner that the clamping effect can be cancelled by pressing the spring ends together. The advantages of the hose attachment according to the invention are, on the one hand, the protected and secure accommodation of the hose connecting point and, on the other hand, the good protection against pulling off and breaking off in the event of a high stress, as a result of which good buckling resistance is ensured.

Patent DE-3500292-A1 (DE)
Inventor: TRUEMPER HEINRICH PROF DIPL IN
IPC: F24H3/06
Filed: 1985-01-07
Abstract: In the method for heating room air, in particular for apartment dwellings, using a heat source which consumes fossil fuels, a water heat accumulator and a heat exchanger device in the waste gas flow of the heat source, an outgoing air heat exchanger being superposed above the heat exchanger, for the room air, and the outside air to be heated being conducted first through the outgoing air heat exchanger and then through the waste gas heat exchanger and being heated in two stages, a further energy optimisation is to be achieved. This is achieved in that the outgoing air, after leaving the first heat exchanger for the outside air, is fed into the combustion chamber of the heat source and, with the waste gas from the heat source, is supplied to the second heat exchanger for the outside air and is carried off as discharge air together with these waste gases. <IMAGE>

Title: Process and device for removing contaminants from waste paper
Inventor: MATZKE WOLFGANG DR ING
IPC: D21B1/32
Filed: 1985-01-22
Abstract: In a process for de-inking or for removing printing inks from waste paper, the prepared fibre material suspension is first floated briefly, i.e. for example for 2 minutes, in a single-stage floatation device (2) and subsequently subjected to a wash in one or more washing stages (7), it being possible for a hydrocyclone (6) to be inserted between the two purification stages. The rejects from all stages are fed without intervening purification to a common internal effluent treatment device (4) which separates the rejects into thick sludge, thick-sludge filtrate and clear water. The clear water and, if desired, also the filtrate of the sludge press are re-used in the system as process water. The process is particularly suitable for removing electrostatic printing inks (laser inks) which are difficult to remove and, in a simple manner and with highly economical water consumption, permits the production of a paper of particularly high purity from waste paper. <IMAGE>

Title: Fastening for superstructures, such as deckhouses and the like, on a ship's deck, in particular for ships used for passage through ice
Inventor: KUNDT KARL-WILHELM
IPC: B63B15/00
Filed: 1985-02-09
Abstract: In the prior art, elastic mountings have been a nuisance due to the flexible movements, in particular pitching movements, associated with them. This is remedied by the invention by virtue of the fact that it provides an additional mechanical clamping and locking device (150) for damping these movements. The clamping and locking device (150) connects the base (11) to the bracket (63) and comprises in particular a connecting bolt (160) which prevents vertical movements virtually completely, while a certain freedom of movement is retained transversely to the longitudinal direction of the ship due to the rotatable mounting of the bottom shank end (161) (cf. Fig. 3). <IMAGE>

Title: Electromagnetic stepping relay
Inventor: HETTICH KARL DIPL ING
IPC: H01H51/08
Filed: 1985-05-31
Abstract: Electromagnetic stepping relays of known models have the property that undefined switching states can occur if the duration of the drive pulse is too short, and these lead to disturbances. In order to preclude this disadvantage, a switching plunger is specified having an integrated spring-force store, in conjunction with a locking spring which can be triggered positively, as a result of which disturbances of the said type are precluded.
Patent DE-3523227-A1 (DE)
Title: Accessory tool for screwing in stud bolts and the like
Inventor: KIPKE HORST
IPC: B25B23/02
Filed: 1985-06-28
Abstract: An accessory tool (1) (Fig. 1) is used to screw in screw-in parts, such as stud bolts or the like, into a workpiece (4), in particular provided with a blind hole (3). The accessory tool (1) has a receiving housing (6) with two coaxial threaded bores (7, 8) of different internal threads, which merge into one anther. One threaded bore (7) is used to receive a part of the projecting region of the screw-in part (2), whereas a counter-bolt (9), serving as an end-face stop for the screw-in part (2), is situated in the other threaded bore (8). The threads on the one hand in the region of the counter-bolt (9) and on the other hand in the region of the screw-in part (2) are designed such that, after tightening a screw-in part (2) in the workpiece (4), only a relative rotational movement between the counter-bolt (9) and the associated thread (8) results upon application of a loosening torque. Consequently, the axial pressure application on the screw-in part (2) is eliminated and the accessory tool can then be unscrewed from the screw-in part without loosening the connection between the screw-in part and the workpiece (4). <IMAGE>

Title: Motor vehicle rear axle, especially for passenger vehicles
Inventor: RICHTER BERND DR
IPC: B60G21/05
Filed: 1985-07-11
Abstract: The invention relates to a motor vehicle rear axle, in which the body-side pivot bearings of its wheel suspension elements carrying the wheels are of elastic or elasto-kinematic design and arranged in such a way that any tendency of the wheel suspension elements to give way to a tendency to oversteer under the effect of lateral forces acting on the wheels, especially when cornering, is counteracted, the wheel suspension elements being on the one hand resiliently supported on the vehicle body in such a way that vertical force components FzL proportional to the wheel normal forces FzH are operative in the body-side pivot bearings and on the other the elastic or elasto-kinematic lateral flexibility of the pivot bearings being adjustable by the effective vertical force components in such a way that this counteraction - for a lateral force effect of equal magnitude - also increases as the vertical force component increases.   <IMAGE>

Title: Circuit arrangement for protecting a pulse-controlled semiconductor switch working as a switch regulator
Inventor: VENEMA TJEERD
IPC: H02M5/293
Filed: 1985-11-08
Abstract: The invention concerns a circuit arrangement for protecting a pulse-controlled semiconductor switch (5) from overloading. Overload protection is achieved using an effective current limiting network working as a two-step controller. For this purpose, an actual value transmitter (6, 17, 18), which represents the effective current, and a comparator (16), which determines the difference between a preset target value and the acquired actual value, are provided. The semiconductor switch (5) is driven by the comparator (16) via switching logic (10, 11), in the case of a positive or negative control difference, using a release signal 1 or a blocking signal 0 respectively, so that in the first case it can continue to be controlled by pulse control, and in the second case it is blocked. The duration of the blocking signal is dimensioned by a time former (14, 15) so that the semiconductor switch (5), acting as a servo component, holds the effective current under the maximum permitted value. This guarantees that the semiconductor switch (5) can always work in the SOAR area. <IMAGE>

Title: Apparatus for the suction removal of pollutants
Inventor: IBENS EWALD
IPC: F16L41/18
Filed: 1986-02-08
Abstract: The apparatus for the suction removal of pollutants has a suction channel and a suction carriage 4, which can travel in the longitudinal direction on the said channel and the slot nozzle 5 of which is guided in the suction channel and slides between corresponding channel lips. These channel lips lie in the region of the side wall and are formed on the one hand by a lower web 16 of the side wall 12 and on the other hand by a sheet-metal wall 3, which is suspended freely movably in the vertical direction in relation to the side wall at its upper edge lying opposite the web 16, at 11, and can move laterally, adjacent to the web, through the slot nozzle 10. As a result, only sheet-metal parts and no rubber lips are used, so that the channel is correspondingly heat-resistant and can also be used for aggressive media. It can be produced inexpensively from galvanised sheet steel. Due to the appropriate suspension of the transverse wall, the latter is not deformed upon movement of the slot nozzle, but is slightly raised. Subsequently, it is lowered down again and no buckling occurs. The sealing effect is also maintained after frequent operation. <IMAGE>
