Patent DE-3115663-A1 (DE)
Title: Device for recovering heat from the stable air of animal husbandry farms
Inventor: HOFFMANN WALTER
IPC: F28D21/00
Filed: 1981-04-18
Abstract: In a device for recovering heat from the stable air of animal husbandry farms, which has a heat exchanger which is to be arranged in the stable space and consists of tube or hose material made from corrosion-resistant plastic, the tube material is provided on a retaining frame in the stable space, above the stable floor, in the form of at least one plastic tube which is essentially helical and wound in the manner of a spiral. A vertical spacing is maintained between the individual tube turns, thus avoiding accumulations of dirt between the individual tube turns and in addition offering large surfaces for extensive formation of condensate. The condensed water which drips down is captured in a condensate receiving trough arranged below the lowermost tube turn, and for the rest develops a desired cleaning effect on the hose material of the heat exchanger, which in addition to being resistant to corrosion thereby has a high freedom from maintenance and is functionally reliable.
Patent DE-3116472-A1 (DE)
Title: Lever drive
Inventor: SEELIGER KLAUS DIPL ING
IPC: F16H37/12
Filed: 1981-04-25
Abstract: The invention relates to a lever drive for double acting conversion of reciprocal movement into rotational movement with a constant direction of rotation. Instead of the crank drive which has the disadvantages of the sinusoidal function and dead-centre points, two directional blocking mechanisms which are driven in opposite directions and act on a power take-off shaft are used, characterised in that the directional locking mechanisms are commercially available freewheels which are driven directly by a common drive wheel and indirectly via an intermediate wheel. The invention is further characterised by the free wheel and return movement lock, adaptable basic transmission, infinitely variable gear change, integrated brake and accommodation of all the functions in a wheel hub gear.

Patent DE-3127118-A1 (DE)
Title: Method and apparatus for the controlled cooling of heated steel strip
Inventor: KOPINECK H J PROF DR RER NAT
IPC: C21D1/84
Filed: 1981-07-09
Abstract: In this method, the heat is removed from the heated steel strip by radiant heat exchange. In order to achieve a particularly economical and simple process for the controlled cooling of a heated steel strip, radiant heat exchange with the heated steel strip is carried out with cooled corresponding walls, the absorption of radiant heat of which can be varied in such a way that control of the strip temperature characteristic is possible. The apparatus for carrying out the method is constructed as follows: radiation walls (2, 3) are arranged at relatively short distances from the steel strip (1), on both sides of the latter, in a cooling furnace, the outsides (4, 5) of the radiation walls (2, 3) facing the steel strip (1) having a high unit conductance and different parts of these outsides (4, 5) being coverable in a controlled manner by means of movable plates or webs with a very low unit conductance. <IMAGE>

Inventor: LINDNER BENGT
IPC: E02D5/28
Filed: 1981-11-19
Abstract: A foundation for a mast, supporting pillar, rails, and the like, comprising an anchoring portion (2) of hollow section design open at the bottom and adapted to be driven into the ground by being vibrated, and a inner (3,3'), and, if desired, and outer (4) ground consolidating element. Preferably at least the inner ground consolidating element (3) is arranged for longitudinal displacement inside the anchoring portion (2) so that the earth entering from below into the interior of the anchoring portion (2) is consolidated during the entire period of sinking the anchoring portion (2) into the ground by vibrating it. In similar manner, also the outer ground consolidating element (4) may be arranged to be displaceable in longitudinal direction. A vibrator suspended from construction equipment or an airship and lowered from the same under loading which acts on the anchoring portion and corresponds approximately to the dead weight of the vibrator (about 1.5 to 3.5 tons) is connected to the upper end of the anchoring portion (2) to sink the same into the ground by vibrating it. The anchoring portion (2) of hollow section design has extremely thin walls as compared to its length and width.

The second switching location is where the optical axes of the individual image inlets and outlets (9-13) intersect each other. These inlets and outlets are provided with guides (14) along which interchangeable mirror elements can be inserted up to the point of intersection of the axes.

Title: Snap-action drive device for an electrical switching apparatus
Inventor: HOEGL VITUS
IPC: H01H3/30
Filed: 1982-02-05
Abstract: A snap-action drive device for an electrical switching apparatus, having a switching shaft (2, 52) which can rotate between two switching limit positions, is connected to moving switch contacts and is driven by means of a force store. During the build-up of the switching force, the switching shaft (2) is locked against rotation by an interlocking device, a single interlocking rod being provided for the interlocking device whose two locking positions which correspond to the switching limit positions of the switching shaft (2, 52) are geometrically locked positions. Depending on the embodiment, the bent rods (11, 65) forming the interlocking rod assume either bent latching positions extended in both locking positions, or an extended bent latching position in one locking position and a folded-up latching position in the other locking position. The interlocking rod can be raised out of its locking positions by means of a release device (29) and then releases a drive shaft (1) and the switching shaft (2) connected thereto, in order to switch the switch contacts. <IMAGE>

Patent DE-3216747-A1 (DE)
Title: Tube head
Inventor: KUTTERER FRANZ
IPC: B65D35/24
Filed: 1982-05-05
Abstract: It is known from toothpaste to add materials of other colours to the actual contents of a tube in order to distinguish this toothpaste from those of the competitors. This is achieved according to the prior art in that an outlet pipe which protrudes into the tube body is provided in the outlet opening of said tube and is mounted in the tube mouth via a rim provided with an opening. Said rim is extremely difficult to manufacture since the openings therein have to be very small in order to achieve the desired small throughflow of material. This difficult manufacture is eliminated according to the invention in that the upper side and/or the underside of the rim tapers at an acute angle towards the outlet pipe or towards the outlet nipple. <IMAGE>

Title: Circuit for driving and braking electrical power units
Inventor: BOEHM HEINZ DIPL ING
IPC: B60L9/30
Filed: 1983-01-15
Abstract: The invention is a device for driving and braking electrical power units, in particular for changing current systems, e.g. for cross-border traffic, using a sequence circuit consisting of a quenchable bridge which is semi-controlled in an unbalanced fashion and a bridge which is semi-controlled in an unbalanced fashion and in which the two bridges can be fed separately from one another by the ac voltage system. In order to make driving and braking universally possible on dc and ac voltage systems accompanied by a simple circuit design, the following is proposed according to the invention: the series circuit of a braking resistor (14) and of a thyristor (13) is arranged in the same direction in parallel between the quenchable valve branch pair and the non-controllable (4.3/4.4 and 4.1/4.2) valve branch pair of the quenchable bridge (4). Between the cathodes of the adjacent 3 valves (4.1, 13 and 4.3) there is in each case one switch (9 and 17, respectively) of which the switch on the side leading to the non-controllable valve branch pair (4.1/4.2) is opened as a travel protection (9) during braking and closed during driving. The switch on the side leading to the quenchable valve branch pair (4.3/4.4) serves as a change-over switch (17) which in the case of ac voltage operation connects the cathodes of the adjacent valves (13 and 4.3) directly to the load circuit and in the case of dc voltage operation connects the dc voltage feed (point A) directly to the load circuit via the travel protection (9) bypassing the sequence bridge (3). In this arrangement, the current is fed back via the quenchable valve branches ... <IMAGE>
