IPC: C12G3/08
Filed: 1986-02-27
Abstract: Disclosed is an alcohol-free yeast white beer and a process for its production wherein the yeast is physically separated from an alcohol containing yeast white beer free of fermentable substances. The beer is then subjected to a vacuum distillation until the alcohol content has been reduced to less than 0.5% by volume to produce a beer concentrate. A corresponding amount of oxygen-free, carbonic acid-containing make-up water is added to the concentrate. Subsequently, top-fermented brewers' yeast is added in an amount above the content normally present in yeast white beer, and thereafter the product is stored at a temperature of from 0 DEG  to 10 DEG  C. Subsequently, yeast is again separated off and thereafter the desired amount of yeast and carbon dioxide is added.

Title: Breech buffer for an automatic firearm
Inventor: STAUFFACHER WERNER
IPC: F41A3/90
Filed: 1986-04-10
Abstract: The breech buffer for an automatic firearm is intended not only to intercept the breech as it travels back after every shot and to knock it forward again for the next shot, but is also intended to prevent the firing rate increasing during rapid firing, that is to say it is intended to be able to convert less kinetic energy into friction and heat initially and subsequently more kinetic energy into friction and heat, in order to keep the firing rate constant. This object is achieved in that, in the case of a breech buffer which has a buffer space (11) which is sealed from the outside and is filled with compressible liquid, and in which a buffer piston (13) is arranged in an axially displaceable manner, additional damping elements (22, 26-29, 46, 52-53) are provided for conversion of the kinetic energy into friction energy. <IMAGE>
Patent DE-3622371-A1 (DE)
Inventor: WILLIE JOACHIM
IPC: G08B13/18
Filed: 1986-07-03
Abstract: With this method the field of measurement of the movement alarm is divided into a number of distance zones within each of which the size of an object remaining or penetrating within the measurement field changes with respect to the size of the measurement field. Each distance zone can be allotted a particular signal amplitude at the output of the movement alarm. Similarly the time interval between entry and exit (if any) of the object is characteristic for each distance zone. The individual distance zones are monitored by means of a selective amplifier, one amplifier stage being allotted to each monitoring zone and the outputs of all the amplifier stages being compared in a comparator unit with predetermined reference values, which are preferably determined by technical measurements. On the basis of predetermined amplitude sequences and/or different signal frequencies, it is possible to detect penetration and subsequent residence in the individual distance zones. <IMAGE>

Patent DE-3632360-A1 (DE)
Title: Process for the selective removal of contaminants from water
Inventor: BOELSING FRIEDRICH PROF DR
IPC: B01D17/02
Filed: 1986-09-24
Abstract: The present invention relates to a process for the selective removal of contaminants from water, e.g. from waste water (effluent), contaminated ground water or drinking water. The process is that water is treated with a reaction partner in the form of a solids preparation which is capable of chemical interaction with the pollutant to form a water-insoluble reaction product and the water-insoluble reaction product and the solids are separated. The solids preparation used can be hydrophobic or hydrophilic, depending on the pollutant to be removed. Biodegradable hydrophobising agents are preferably used, such as natural fatty acids or alkanes. It is further advantageous if the hydrophobic solids preparation contains the starting material or the reaction product of a dispersing chemical reaction. Calcium oxide or an aluminium alcoholate can serve as starting material for the dispersion by chemical reaction.
Patent DE-3634951-A1 (DE)
Title: Mast-boom connection of a windsurfing rig
Inventor: PERTZEL KURT
IPC: B63B35/79
Filed: 1986-10-14
Abstract: Summary: Until now, the rope-end connection of the boom front end with the mast has been a problem: if it was made too large, there were undesirable tolerances, i.e. the boom "wobbled" on the mast. If it was made too small, this could cause damage to the mast if the boom was swivelled about the boom-mast connection point to the position of the sail's clew when rigging. A solution that saves time and effort is the mast guide bushing integrated into the boom front end (Fig. 2), which eliminates the rope-end connection of the boom front end to the mast. The sail is then spread with two ropes only: with the trimming sheet at the end of the boom, and with the luff jig at the mast base. <IMAGE>

Title: Method and device for camouflaging and for reducing the infrared radiation from water craft
Inventor: WILLRODT GUENTHER DIPL ING
IPC: B63G13/02
Filed: 1987-03-03
Abstract: A method for camouflaging and for reducing the infrared radiation from water craft, in which water, preferably seawater taken from the vessel's surroundings, for example from greater depths, is pressurised and then atomised outside the vessel in such a way that a coherent camouflage cover matching the outline of the vessel is formed. It is characterised by the atomisation of the water being done in such a way that a layer of very fine water droplets is formed, and by this layer of water droplets being exposed to a current of blown air at an angle to the layer immediately after being atomised, so that the layer is dissolved into a sort of fog. The temperature and pressure or amount discharged of the water and of the current of blown air are adapted to one another according to the laws governing humid air (i-x diagram) in such a way that complete saturation of the current of blown air is always achieved in all operating conditions. <IMAGE>

Title: Flame monitoring device with thermocouple
Inventor: GISKE DIETRICH DIPL ING
IPC: F23N5/10
Filed: 1987-05-19
Abstract: Flame monitoring devices with thermocouples are used in stationary and mobile burners that are fired with liquid or gaseous fuels. They signal the presence of the flame, and trigger switching processes as a function of the signal. The invention is intended to provide a rugged monitoring device that can be manufactured easily, and amplifies the thermoelectric e.m.f. without faults or bounce, and reliably over a wide temperature range, so that drivers can be switched. The object is achieved according to the invention by having the thermoelectric e.m.f. of a thermocouple generate an electromagnetic field in a coil with an iron core, which can be constructed as an open or closed magnetic circuit. There is a Hall-effect circuit in the air gap of the iron core, which is activated by the lines of flux of the electromagnetic field. If the Hall-effect circuit, which is supplied with an internal operating voltage, reaches its operating value due to the induction density, its output signal switches drivers for switching the ignition, fuel and air supplies on or off. <IMAGE>
