Title: Method and device for pouring gaseous drinks into bottles
Inventor: BROLL ADALBERT
IPC: B67C3/10
Filed: 1988-06-07
Abstract: The invention is used to pour gaseous drinks into bottles and relates to a method and a device, in the case of which each bottle is raised so that it is pressed in a gas-tight manner against a centring valve of a filling valve and is evacuated, and the introduction of inert gas into the bottle brings about a precisely defined mixture ratio of the air remaining in the bottle and the inert gas which has been introduced, the said inert gas/air mixture is evacuated once again, and then the bottle is preloaded, filled, relieved and taken away. The object of the invention is to pour gaseous drinks into bottles or the like while ensuring that the liquid absorbs as little oxygen as possible and that very sparing use is made of inert gas. An essential feature is that, when the bottle has been filled, gas still remaining in the upper region of the said bottle is guided to a relief chamber, where the pressure is reduced to the ambient pressure, the relief chamber is closed and the said gas is sucked as an inert gas into a subsequent bottle to form the precisely defined mixture ratio. The solution according to the invention consists in the fact that the pipe between the relief valve and the aperture leading to the atmosphere has a relief chamber arranged in it.

Filed: 1989-03-13
Abstract: The invention relates to the separation of nitrogen oxides from gases and exhaust gases by oxidation of NO to NO2. According to the invention, the oxidation proceeds with the aid of oxidising agents which are formed in the gas stream by reaction of sodium chlorite and/or sodium peroxide with inorganic acids. In this case they are chlorous acid and hydrogen peroxide. The NO2 formed is immediately trapped by coinjected basic material, e.g. calcium hydroxide, and separated off at separators, e.g. electrostatic precipitators. The NO2 formed can also be separated off in scrubbers operated under alkaline conditions or on solid layers or packed bed filters. The apparatus according to the invention comprises a metering device, a mixing section, e.g. a reactor having baffles and mixing devices, and a separator, e.g. an electrostatic precipitator or cloth filter.
Patent DE-3910906-A1 (DE)
Title: Method for direction forming in the case of a towed acoustic underwater antenna
Inventor: MEUSER WILFRIED DIPL ING
IPC: G01S3/802
Filed: 1989-04-05
Abstract: The direction forming in the case of a towed underwater antenna achieves greater directional precision and unambiguous side designation by means of the following method. The lateral deflection of the hydrophone which is at the front in the towed chain is measured continuously at a clock frequency which is defined by the towing speed and the hydrophone separation in the towed chain and is stored in a memory having a shift-register function, the number of storage locations in which corresponds to the number of hydrophones on the towed chain. The echo-sounding ranges, which are normally determined in order to calculate the required time delays for the output signals of the hydrophones, which are lined up in the towing direction, are corrected, using these stored values, with respect to their echo-sounding points located on an axis which is transverse with respect to the axis of the directional characteristics, and only then are the delay times calculated from the corrected echo-sounding ranges. During the correction, stored values are assigned to the echo-sounding ranges in the sequence of hydrophones defined by the towed chain, in such a manner that the stored value stored last corrects the depth-finding range of the front hydrophone in the towing direction in the towed chain and the stored value which is stored before a number of storage cycles corresponding to the number of hydrophones in the towed chain corrects the echo-sounding range of the hydrophone which is last in the towing direction.

Inventor: GRADERT DETLEF DIPL ING
IPC: B60G17/052
Filed: 1989-06-14
Abstract: The dryer for compressed air delivered from a source to a consumer unit is periodically regenerated by air at considerably lower pressure than that of air from the emptying consumer  unit. This pressure redn. is normally effected by a throttle in the line connecting consumer unit to dryer during emptying of the former. Between consumer unit and throttle is now disposed a balancing container to receive discharging air from the consumer unit during emptying and to deliver air via the throttle (24) to the air dryer. The air line from consumer unit to balancing container has a greater cross section than the throttle.  Excess air from the balancing container is discharged to atmos.  under the-control of a pneumatic valve actuated by container  pressure. USE - Used for vehicles with adjustable air springing. The control and operating procedure during regeneration are now made faster, and largely independent of throttle condition.

Title: Bobbin conveyor - has angled guide rails at one side of the path to keep bobbin carriers in friction contact with the conveyor
Inventor: BUCKEN RENE
IPC: D01H9/18
Filed: 1990-05-22
Abstract: The conveyor system to transport carriers for bobbins and bobbin sleeves, in the form of a base plate and an upright holding spindle, has a guide rail (6,7,8,9) to one side of the path (10) of travel, to guide the separate bobbin carriers (3). The guide rails increasingly range into the movement path, angled downstream, and across the line of travel. Pref. several guide rails (6,7,8,9) are located alternately on both sides of the movement path (10), behind each other, leaving a free passage for the carriers when moving from the end of one guide rail to the start of the next. Cover plates are fitted to give a gap between them and the moving surface (10') of the conveyor (10) which is greater than the height of the base plate of the bobbin carriers, and the gap between the facing edges of the cover plates is less than the carrier base plate dia. The cover plates cover a wider section of the conveyor on both sides than the space taken up by a guide rail at one side or the other of the travel path, at all points along the movement path. A shaped profile section, to give a rolling path movement, is at each conveyor branch path junction and/or the entry to a branch channel, placed opposite to a guide rail. The gap between the facing edges of the cover plates is reduced by a projection at the branch path junction. Conveyor belts are used as the moving surfaces (10') in the transport assembly (10). ADVANTAGE - Designed for the movement of bobbin and sleeve carriers between machines, such as between spinning and winding assemblies and pref. in a closed loop, the friction drive action on the separate carriers is maintained which not only gives a self-cleaning action to the conveyor surfaces but also reduces the frequency of bobbins bunching together.
