Patent DE-3613699-A1 (DE)
Title: Lightweight hull
Inventor: STEEN GERHARD DIPL ING
IPC: B63B7/08
Filed: 1986-04-23
Abstract: The invention relates to a lightweight hull which is obtained when an airbag is clamped between two thin plates on three sides, namely bow, stern and keel, by screwing, rivetting and/or adhesive bonding or welding. Through injection of compressed air into the airbag, a fluidically advantageous boat shape results by the lightweight hull opening at the top towards the open side and obtaining the very favourable strength values due to the resulting dimensional stability and the amount of pressure applied. This boat shape is especially suitable for the construction of catamarans. To improve the manoeuvrability of the abovementioned lightweight hull, the air pressure present in the airbag can be utilized by a portion of the compressed air being directed via a valve to the rudder, where the discharging compressed air is utilized as a control drive via a compressed-air motor with propeller or via a nozzle according to the reaction principle.

Title: Device and method for filling and cleaning beer barrels (kegs)
Inventor: MALEK HERBERT
IPC: B67C3/34
Filed: 1986-06-09
Abstract: The invention relates to a device for filling beer barrels (kegs) of metal, plastic or a combination of these substances or for cleaning and sterilising such barrels, which have a floor fitting and an ascending pipe which is connected to the latter and extends into the interior of the barrel. The device has a processing head (2) with an ascending pipe reception device (1) which is situated above the latter, a combined liquid inlet and outlet (3), a liquid inlet (4) and a pusher rod (5) which is moved through the processing head (2). The axis of the combined liquid inlet and outlet (3) pipe is at an angle of less than 90 DEG  to the axis of the ascending pipe, so that the influx is tangential and therefore laminar and without turbulence. The pusher rod (5) has, inside the processing head (2), a tubular casing for guiding a liquid. Using the method according to the invention, the liquid is introduced into the keg tangentially to the wall of the ascending pipe with a component pointing towards the upper end of the pipe. <IMAGE>

Title: Process for purifying a flue gas stream from SO2 and NOx
Inventor: PAUR HANS RUDOLF DR
IPC: B01D53/60
Filed: 1986-07-05
Abstract: The invention relates to a process for the simultaneous dry purification of a flue gas stream, separating off SO2 and NOx by electron irradiation and addition of ammonia, SO2 and NOx being converted into ammonium sulphate and ammonium nitrate, which themselves are separated off from the exhaust gas stream. The object underlying the invention is to improve the process mentioned at the outset in such a manner that the energetic efficiency is increased and complete removal of NOx can be achieved. The object is achieved by some of the purified exhaust gas stream being able to be fed under control via a recirculation section to the flue gas stream.

Patent DE-3630368-A1 (DE)
Title: Vibration transducer and method for manufacturing it
Inventor: IKEDA KYOICHI
IPC: G01L1/18
Filed: 1986-09-05
Abstract: A vibration transducer contains a vibration bar which consists of an n-type layer and is fixed at at least one end and is shaped by selective etching of an n-type layer which has been produced by local doping of a silicon monocrystal with foreign atoms. Furthermore, the vibration transducer contains devices for allowing the vibration bar to vibrate as well as devices for tapping off the vibration of the vibration bar. The vibration transducer is capable of measuring pressure, temperature, density etc. by detecting a change in the resonance frequency of the vibration bar. The vibration bar can be finely etched independently of its doping density in that it is formed in an aqueous alkaline solution with the application of a negative direct voltage or a pulsating voltage to a p-type layer and of a positive direct voltage or a pulsating voltage to an n-type layer. The vibration and tap-off devices for the vibration bar can be readily provided by constructing a diode and a transistor, enclosing the vibration bar, in the vibration transducer.

Title: Device for producing (generating) stimulation pulses
Inventor: SPILLECKE VOLKMAR DIPL ING
IPC: A01J5/007
Filed: 1986-11-07
Abstract: Various methods have been disclosed for stimulation of the cow's udder but, although they produce a good milk yield, their cost is excessively high. It has been found that radio-frequency oscillations during each suction or pressure phase or during both phases produce a stimulating effect. The object of the invention is to transfer this radio-frequency oscillation from the known in-phase principle to a two-frequency pulsator which can be operated both at a duty ratio of 50:50 and with extended suction phase. The object is achieved according to the invention in that a switching valve is connected between the pulsator and the milk container, preferably instead of the air distributor on the milk collecting element, which switching valve lets in a small amount of air several times in a pulsed manner during the suction cycle. If the air is taken from the other pair of milk containers, then the same effect occurs on the pressure side automatically. <IMAGE>

Abstract: Devices on vehicle wheels, not consisting of enveloping chains, for avoiding spinning and aquaplaning of wheels and for increasing the contact area. This is achieved by means of a kind of attachment wheel which is attached to the rim/wheel hub. The grip elements which come into contact with the carriageway can be drawn in under normal ground conditions. Devices whose elements cannot be disengaged are designed such that when the carriageway is in a normal condition no adverse effects are caused as the wheels roll. The grip elements are designed in shape and material of composition essentially in accordance with their function. <IMAGE>

Title: Circuit arrangement for telecommunications switching systems, in particular telephone switching systems, with an at least partially meshed network of channel groups and with routing devices
Inventor: DAISENBERGER GEORG DIPL ING
IPC: H04M3/36
Filed: 1987-05-22
Abstract: Circuit arrangement for telecommunications switching systems, in particular telephone switching systems, with an at least partially meshed network of channel groups and with routing devices. Following successful seizure of an outgoing line in each case, unsuccessful call set-up attempts are counted on a group-individual, code-individual or code-part-individual basis and processed to form group-individual, code-individual or code-part-individual traffic overload grades in relation to the respective corresponding successful call set-up attempts or to all respective corresponding call set-up attempts. New call set-up requests are selectively marked on a group-individual, code-individual or code-part-individual basis according to these traffic overload grades in such a way that they are in some cases rejected according to the latter or are subjected during routing to a restriction which excludes a corresponding group. When group-individual traffic overload grades are formed, the corresponding groups can also be marked as inaccessible for the connection requests concerned. <IMAGE>

Title: Method and device for the determination of the liquid content of at least one container filled partly with liquid and partly with gas
Inventor: IGENBERGS EDUARD PROF DR
IPC: G01F23/14
Filed: 1987-06-11
Abstract: A method is described for the determination of the liquid content of containers which are filled partly with gas and partly with liquid. In the method the volume of gas present in the container following a compression or expansion process is determined from the work delivered or extracted in the course of the compression or expansion and the consequent change in the pressure of the gas. The liquid volume is then determined from the difference between the presumed-known predetermined container volume and the gas volume.
