Patent DE-3215864-A1 (DE)
Title: Ventilation fan
Inventor: KORFMANN WERNER
IPC: F04D25/02
Filed: 1982-04-29
Abstract: The invention relates to a fan for tunnel or underground ventilation as a combination construction, that is, with an electric motor and a compressed-air turbine for one or more fan wheels. The compressed-air turbine is arranged coaxially to the shaft of the electric motor, and its impeller is connected to this shaft in a rigid manner or via a coupling. Unlike this construction, the invention proposes a two-shaft construction in which each shaft is preferably connected to the fan wheel via a free-wheel. Due to the arrangement of the compressed-air turbine within the ventilation flow and no longer outside the fan tube, a largely free configuration is possible, and the materials can also be freely selected, since there is no longer the risk of sparking in the event of damage.
Patent DE-3216598-A1 (DE)
Title: Process and apparatus for extraction of solar heat and supplying this heat to water circulating circuits for heating dwelling spaces
Inventor: WESSA THEO
IPC: F24S10/60
Filed: 1982-05-04
Abstract: In the case of brine circuits mounted in the open air or buried in the ground as pipe coils, the efficiency decreases on icing such that the operation of this apparatus is no longer economical. Leaks due to corrosion are also very problematical, the soil and ground water being contaminated with escapes of brine, coolant and oils. To eliminate these disadvantages, water heat is extracted with an ice preparer. Water heat is extracted down to the minus region by this extraction apparatus. The resulting bodies of ice are transported to the open air and fall into a collecting container, beneath which water-conducting plates and water containers are arranged. The water is conducted by a pump into the ice-collecting container; the ice melts, and the melt water is again heated on the water-conducting plates and used again for heat extraction. During operation below the frost limit, the pump is switched off, and conduit, ground or other water is used for extraction. The resulting ice bodies are aggregated until they are melted again by reaching the exterior temperature above 0 DEG C due to solar heat, and are returned to the ground water. When the temperature rises, the pump for circuit operation is switched on again.

Title: Clamping device for samples to be examined microscopically, with background neutralisation
Inventor: FINK MANFRED
IPC: G02B21/34
Filed: 1982-06-02
Abstract: The invention relates to a miniature clamping device for sample fixing, which can be used in microscopes, in particular in scanning electron microscopes. The aim of the clamping device is to fix releasably, without problems, without damage and rapidly as many samples as possible, which differ in their geometrical shape, in construction and in material. It also has the aim of neutralising disturbing background phenomena in scanning electron-microscopic sample images. The aim is achieved by miniaturisation of a modified vice which is fastened on lockable spherical joints and between the jaws of which the sample is held with adjustable force. The clamping force, which is applied by a pretensionable helical spring, can be both finely adjusted and varied within a large range. The clamping jaw attachments are removable and can be exchanged for other or sample-specific special models. The lockable spherical joints allow positioning of the clamped sample in the respectively most favourable observation position. The background neutralisation is carried out by an exchangeable and movable potential plate.

Patent DE-3238272-A1 (DE)
Title: Domed profile, especially a rolling profile
IPC: E04C3/07
Filed: 1982-10-15
Abstract: The invention relates to a rolling profile having domed surfaces for increasing the stability, especially with respect to bulging and buckling. In addition to the high load capacity of such a profile, with a small material mass, such a multi-piece profile with longitudinally directed domed surfaces can be deformed using simple bending tools to form V-shaped or U-shaped hollow profiles. This results in a universal application capability for many design requirements in structures above and below ground, for example for high load capacity ceilings, as well as supporting works for bridges, having a low intrinsic weight. The deformation by developing the domed surfaces to form hollow profiles takes place in the most simple manner over the easily deformable half curves, with slight plastic deformation between the domed surfaces. The half curves extend in the opposite direction to the major radii of the domed surfaces of the profile. A further advantage arises during storage, because of the low space requirement of the undeformed profiles and the small number of different profiles.

Patent DE-3314104-A1 (DE)
Title: Sealing head with a device for feeding wet adhesive strips for box-sealing machines
Inventor: BEECK LOTHAR
IPC: B65B51/06
Filed: 1983-04-19
Abstract: The device mentioned has a pair of rollers for transverse shaping of the adhesive strip, to make it buckle-proof in a longitudinal direction. The invention also has an adhesive strip cutting device downstream of the pair of rollers and downstream of that an outlet slot with a device for moistening the adhesive strip. So that the adhesive strip can be conveyed in a longitudinal direction without buckling and be stuck satisfactorily to the box which is to be sealed, the shaping system of the rollers comprises a plurality of elongate projections which are arranged next to each other at an axial distance and which extend in a circumferential direction, and recesses, which engage with one another when the rollers come into contact with one another. In addition, the width of the outlet slot is kept smaller than the height of the adhesive strip shaping produced, so that this shaping is substantially removed again when the adhesive strip emerges.
Patent DE-3319067-A1 (DE)
Title: Tension-strand chain for special track-laying vehicles
Inventor: LIERMANN HELLMUTH
IPC: B62D55/24
Filed: 1983-05-26
Abstract: The invention provides for this purpose a tension-strand chain for special track-laying vehicles which is based on a flat-tooth engagement principle. The tension-strand chain, produced under precise conditions in full moulds, with teeth for the drive is constructed so as to ensure a fixed engagement in the tooth spaces of the axle drive. The engagement and coasting of the teeth takes place in a manner free from excessive friction; they largely correspond in their function to the teeth of a chain drive or of a gear drive. The tension-strand chain consists of a continuous element made from spirally twisted steel cord. The latter represent the most important component of the tension strand and are the secret of the exceptionally high tear resistance, the excellent bendability and the slight extension. The abrasion-resistant, flexible profiled rear of the tension strand encases the tension-strand chain, which transmits the power. Produced from high-grade, loosely cross-linked polyurethane (such as Vulkollan, Trolastik, Neothan etc). The latter protects the tension-strand chain when in use against external stress and strong abrasion (these plastics have 48 times the abrasion resistance of rubber). In the case of special applications of the tread, special profiles can be chosen for the particular use. <IMAGE>

Title: Method and device for acoustically detecting bubbles in a medium
Inventor: BARZANTNY JOACHIM
IPC: G01N29/036
Filed: 1983-06-21
Abstract: A method of acoustically detecting bubbles in a medium from the attenuation of soundwaves is largely interference-free and independent of other parameters. The medium (2) is induced to vibrate by white noise or by means of selected frequencies from a vibration transducer (5). The resonance spectrum produced, which contains one or more resonance lines whose amplitude is essentially dependent only on the bubble content of the medium (2), is picked up by an acceleration transducer (7). The amplitudes of the bubble-sensitive resonance lines are monitored and indicate the bubble content of the medium. The sound transducers (5, 7) used are preferably magnetostrictive vibrators mounted on the outside of the structure (1) containing the medium (2). The invention makes it possible to monitor a liquid, in particular a coolant in a reactor circuit, for the presence of bubbles. <IMAGE>

Title: Solar-powered system for the scooping and pumping of liquids
Inventor: MUELLER WALTER
IPC: F03G6/00
Filed: 1983-11-05
Abstract: In this system a high-pressure vessel and a low-pressure vessel are connected by a liquid- and a pressure-equalising pipe, which is fixed on a shaft. The high-pressure vessel is filled with an easily vaporising working medium and provided with a solar collector. Beneath the solar collector a reflector with swivelling side sections is deployed. A condenser provided with a water cooling device is arranged on the low-pressure vessel. It is protected at the sides and from above against solar radiation. Due to the thermodynamic process between solar collector and condenser the liquid of the working medium is made to move to and fro between the high- and the low-pressure vessel, the system performing a cyclical swivelling movement. At the end of the shaft a scoop device is fitted by means of which water is raised upwards. The precise working cycle has already been described in the description. The system is a hermetically sealed self-contained system. It is mainly intended for irrigation purposes.

Title: Circuit solution for the unrestriced use of peripheral chips of the Z80 family of microprocessors by ZILOG over the entire directly addressable input/output range
IPC: G06F9/48
Filed: 1983-12-08
Abstract: For this purpose, it is necessary to achieve parallel processing of the end acknowledgement in asynchronous processes in the vector interrupt since otherwise, due to transit times through the existing daisy-chain lines of the physical priority chain, the input/output chips would result in these systems being blocked if more than four of the family are present. A fixed decoder circuit is used in order to supply the input/output units temporarily with a signal in parallel with the programmed termination, namely RETI (return from maskable interrupt). This bypasses the delay due to the priority chain provided by the manufacturer, and the transit delays produced by the serial data run are reduced to exactly one chip-specific transit time.
