Title: Control system for the ventilation of the drying hood of a paper machine
Inventor: VIRTA RAIMO
IPC: G05D27/02
Filed: 1986-09-09
Abstract: The invention relates to a control system for the ventilation of a paper machine drying hood (10), by which both the exhaust-air stream (m2) diverted from the hood and the replacement air stream (m1) fed to the hood are measured and controlled. In the process, the moisture level and the temperature of the exhaust-air flow are measured. The control system comprises two control loops. With the first control loop (23, 24, 26, 27, 30, 31, 32, 33), the moisture level of the exhaust-air flow is measured and, by influencing the amount of exhaust air (m2), its moisture level is controlled to a predetermined value by a setpoint unit (33). With the second control loop (14, 15, 16, 17, 19, 20, 21, 22) of the control system, the 0 point of the difference between internal pressure and external pressure of the hood (10) to be ventilated, i.e. the so-called 0 level of the hood, is kept at a constant level by measuring the amount of exhaust air (m2), controlled by the first control loop, and setting the setpoint of the amount of replacement air (m1) of the second control loop to a value corresponding to the constant 0 level of the hood (10), determined in advance (Fig. 2) and introduced into the control loop or stored. <IMAGE>

Patent DE-3636202-A1 (DE)
Title: Composite material
Inventor: HEITZER JOERG
IPC: C04B35/80
Filed: 1986-10-24
Abstract: Composite material, such as for example fibre-reinforced ceramic, comprising a matrix and a reinforcing material embedded therein for taking up mechanical and/or thermal loads in an elongated, fibre-like structure. Here the reinforcing material or the fibre-like structure 8 has at least one local thickening 11 of the cross-section or increase in its surface area. Furthermore, a plurality of fibre-like structures 8 can be present in the matrix 7, each of which has at least one local thickening of the cross-section or increase in its surface area. With such a structure of the reinforcing material, the crack extension of a crack is inhibited by it being diverted at a bulge and arriving in a pressure region of the internal stress distribution. In this way, the crack tip is closed and the crack is stopped. The new composite material enables the crack growth phase as a component of the residual lifetime of a component manufactured from the new material to be considerably increased. <IMAGE>

Title: Mobile container system
Inventor: BISCHOFF RAINER
IPC: E04H1/12
Filed: 1987-02-12
Abstract: In order further to improve the container system according to Patent Application P 3529556.2, provision is made, according to the invention, to separate the hitherto conventional, single-piece corner profile into a plurality of function profiles. Said function profiles can be pushed together, longitudinally with respect to themselves, to produce a form-fitting arrangement which can be subjected to very high loading, in addition to high loadability, extreme leaktightness also being achieved due to the dovetail principle of the form fit. Furthermore, this function separation is used according to the invention to optimise the form-fit/carrying profiles such that much higher loading can be carried and transferred. The form-fit/carrying profiles have a circular cross-sectional part. Weather strips can be pushed into this by means of their circular cross-sectional part, said weather strips having at least one outwardly projecting web. Any supports, carrying means, etc. can be connected to said web, on the one hand and, on the other hand, the webs themselves or mouldings can be designed for maximum loadability.

Abstract: For storage in order to enable the playback of transmissions accompanied by an identification code, such as traffic announcements from broadcast transmitters, it is proposed that storage of the transmission or transmitted information be initiated by the appearance of the identification code while the latter is being transmitted, a reset to the initial condition being carried out, in particular at the end of the identification code, and/or a control signal being also stored at the end of the storage. The information storage can be aborted manually, a further reset being carried out automatically at the end of the information playback. As a development, provision is made for the initiation of the playback to be aborted or blocked while the identification code is being received and further storage to be carried out.
Patent DE-3710106-A1 (DE)
Title: Warm bedding-down surface with automatic slatted flooring
Inventor: KLASEN ANTON
IPC: A01K1/015
Filed: 1987-03-27
Abstract: The application area of this warm bedding-down surface is in agricultural livestock barns. Said system permits the production of barn floors which are very good for the animals from a physiological point of view, but, at the same time, also cut down on a large amount of work in the barn for the farmer. The finished bedding-down surface comprises narrow webs and narrow gaps. The webs are coated with rubber or plastics. The gaps can be closed by a device in that round bars are pressed into the free gaps. These are likewise coated with rubber or plastic. A large surface area which is advantageous for the animals is thus obtained. Most of the excrement from the animals can readily and immediately fall, through the many open gaps, into the manure pit located beneath. The risk of injury is reduced virtually to zero since all the gaps are very narrow, in contrast to those in concrete slatted floors. In order to ensure its load-bearing capacity, said system is made completely of iron. Jamming of the raising apparatus is prevented by a scissors-type mechanism. Consequently, the structure is maintenance-free.

Title: Two-stage gearbox
Inventor: SCHNEIDER ARTHUR ING GRAD
IPC: F16H3/089
Filed: 1988-03-05
Abstract: A two-stage gearbox for vehicles, especially passenger motor vehicles, is described which has a gear pair (3, 4; 5, 6; 7, 8; 8, 10), assigned to each transmission gear and constantly meshing with one another, each of which gear pairs respectively comprises a fixed gear (3, 6, 8, 9) rotationally fixed to a transmission shaft and a loose gear (4, 5, 7, 10) held so that it can rotate on another transmission shaft. In addition, the gearbox has means of coupling (14, 15; 20, 21; 26, 27; 31, 32) for connecting each of the loose gears to a component rotationally fixed on the other transmission shaft. In order to achieve the shortest possible overall axial length of the two-stage gearbox, it is proposed that in addition to a loose gear of the one transmission gear, a fixed gear of another transmission gear be arranged on each transmission shaft (1, 2) and that the means of coupling be designed for connection of the loose gear to the adjacent fixed gear. At the same time, the means of coupling assigned to each respectively adjacent gear pair may be arranged on the two transmission shafts in essentially the same radial plane. <IMAGE>

Title: Circuit arrangement for bidirectional control of DC motors or DC chopper converters (controllers)
Inventor: RABL HELMUT DIPL ING
IPC: H02P7/03
Filed: 1988-04-08
Abstract: Full-bridge circuits are known for bidirectional control of DC motors or DC chopper converters, which have relay switches or semiconductor switches in their bridge limbs as switching elements. In addition to their limited switching speed, relays have the disadvantage that, during switching, contact burn due to sparking occurs on the relay contacts. The invention provides a semiconductor switch (9) which can be controlled by a control device (16), with which switch the current flow through the DC motor (14) can be interrupted and the switching elements (5, 6, 7, 8) can thereby be switched in the unloaded state. <IMAGE>

Title: Damping hose for water pipes
Inventor: KNAPP ALFONS DR
IPC: F16L55/033
Filed: 1988-04-30
Abstract: Damping hose (3) which is intended for introduction into a water pipe, in particular a connection pipe to a water tap, and in the case of which outer sealing flanges (1) and a yielding wall (2) are provided, said walls being connected to the flanges in a sealing manner and delimiting an air pocket C. The yielding wall of the hose has, in the absence of a water pressure, a pronounced convex form which affects essentially its entire extent and causes a narrow through-passage which is small in comparison with that which is required when a pressure prevails. Under operating pressure, the air in the air chamber is compressed and the yielding wall becomes approximately cylindrical, while the narrow through-passage widens and becomes large enough to permit the liquid flow to pass through it. The configuration of the hose ensures an increased damping effect of the air chamber and a reduced disruption of the water flow through the damping hose. <IMAGE>

Title: Method for the maintenance of a constant mixture ratio in the supply of a secondary medium into a primary medium flow and device for carrying it out
Inventor: BRECKNER KURT DIPL ING
IPC: G05D11/13
Filed: 1988-06-02
Abstract: Method for the maintenance of a constant mixture ratio in the intermittent supply of a secondary medium into a dimensionally varying volume flow of a primary medium and device for carrying it out. A constant predetermined mixture ratio is intended to be automatically maintained in a way which is procedurally simple and reliable in the case of a varying primary medium flow. The primary medium flow is measured via a standardised signal (Aqp) and compared with a standardised signal (At) as a measure of the delivery time of the secondary medium. The two standardised signals are so matched to one another, that at the maximum primary medium flow, secondary medium is delivered in continuous operation. At lower primary medium flow, interruptions of the secondary medium delivery take place. The novel method can advantageously be applied in the additive mixing of fragrances.

Title: Insert for damping turbulence in pipelines
Inventor: PROESCH HELMUTH
IPC: F16L55/027
Filed: 1988-07-01
Abstract: The invention relates to an insert for damping turbulence in pipelines. In addition to the undesired effects of erosion and, as the case may be, cavitation as well, turbulence is also bound up with flow noise. Consequently, to date provision has already been made on valves of elements which served to reduce flow noise. In order to damp turbulence in pipelines, in particular on ships, which is initiated by branch-offs or deflections, the invention provides to divide the overall flow into numerous partial flows which are guided in mutually parallel ducts in such a way that essentially laminar partial flows of the same direction and approximately the same speed are produced. The insert according to the invention consists of an essentially cylindrical housing in which devices for laminarising the flow are accommodated. In a special embodiment, the flow is guided in an approximately radial direction in a plurality of juxtaposed sections. By means of suitable deflecting plates (baffles) between these sections, the flow in immediately adjacent sections takes place in mutually opposed radial directions. In a further special embodiment the laminarisation is performed in parallel, axially arranged ducts.

Title: Typewriter or similar office machine having an exchange device for a daisywheel-exchange cartridge
Inventor: KITTEL ARTHUR ING GRAD
IPC: B41J25/24
Filed: 1988-07-13
Abstract: In typewriters or similar office machines, having a daisywheel designed as a sum type carrier, it is known to arrange said daisywheel in an exchange cartridge for an easier exchange operation. In this exchange operation, the daisywheel has to be uncoupled from the daisywheel selection motor before the exchange cartridge is removed from a holding device, which, in the known arrangements, takes place by means of a pivoting movement of the type selection motor away from the roller platen. Since the individual components of the printing mechanism are located very close together, the exchange of the exchange cartridge is still quite difficult in the known arrangements. The disadvantages listed above are avoided according to the invention by a drive device which contains a drive motor (39) and by means of which a holder (46) with the type selection motor (7) for disconnecting or connecting the daisywheel (5) from/to the drive shaft (58) of the type selection motor is displaceable and a holding device for the exchange cartridge (22) can be raised into an exchange position on the slide (4) for removing the exchange cartridge (22) and can be lowered again automatically after exchange of the exchange cartridge (22). At the touch of a button, the holding device of the exchange cartridge (22) is automatically moved into an exchange position, the disconnection of the daisywheel (5) from the output shaft (58) taking place automatically. In an advantageous design, the exchange cartridge can ... Original abstract incomplete. <IMAGE>
