Patent DE-3045480-A1 (DE)
Inventor: LEDJEFF KONSTANTIN DIPL PHYS D
IPC: H01M10/52
Filed: 1980-12-03
Abstract: A closure device for lead-acid batteries includes a filter of granulated activated carbon treated to be hydrophobic combined with means for preventing explosion of emitted hydrogen and oxygen gas. The explosion prevention means includes a vertical open-end tube within the closure housing for maintaining a liquid level above side wall openings in an adjacent closed end tube. Gases vent from the battery through a nozzle directed inside the closed end tube against an impingement surface to remove acid droplets. The gases then flow through the side wall openings and the liquid level to quench any possible ignition prior to entering the activated carbon filter. A wick in the activated carbon filter conducts condensed liquid back to the closure housing to replenish the liquid level limited by the open-end tube.

Title: Apparatus for cleaning bottles
Inventor: RUEPPELL CHRISTIAN DIPL ING
IPC: B08B9/30
Filed: 1981-05-11
Abstract: A cost-effective bottle-cleaning process using the apparatus suitable for carrying it out is described. It is distinguished in that the lye-treatment part is divided into different temperature and concentration zones. The actual bottle-cleaning process is carried out in a central lye bath at high treatment temperatures. In this bath or this hot lye zone, additional treatment baths are arranged upstream and downstream and permit extensive recuperative heating of the machine and expedient lye recycling. This results in a substantial reduction in heat consumption while at the same time minimising the fresh-water requirement.
Patent DE-3123317-A1 (DE)
Title: Device for positionally securing the bridge deck of a ramp loading bridge
Inventor: ALTEN KURT
IPC: B65G69/28
Filed: 1981-06-12
Abstract: The invention starts from a device of this type in which the free end of a pendulum-type support forms a stop in the approximately vertical rest position of the bridge deck, and an extension of this pendulum is arranged in a window of the bridge deck. In order to ensure that said extension does not constitute a hindrance during bridge operation, the invention provides that the extension form with the pendulum an angle of approximately 60-90 DEG . As a result, the extension passes into the plane of the bridge deck when the bridge is in operation, whereas in the rest position of the bridge the extension projects so as thus to make it possible to operate, or swing, the pendulum, for example using foot pressure.

Patent DE-3149401-A1 (DE)
Title: Heating installation
Inventor: ZEDDIES FRIEDRICH ING GRAD
IPC: F24D19/10
Filed: 1981-12-10
Abstract: In a heating installation with central temperature control and decentral quantity control, circulating means are used in such a stepped manner that the difference in delivery level from step to step is the same. In the event that the differential pressure falls below an adjustable value, transducers for differential pressure close to the consumers cause a sequence processor to trigger the next largest delivery device and vice versa. The installation according to the invention avoids regions of poor control behaviour and flow noises at thermostat valves and the like and saves circulating energy. It can be used for heating and ventilation and air-conditioning installations. <IMAGE>

Patent DE-3300075-A1 (DE)
Title: Exhaust gas-free vehicle ventilation system
Inventor: KOERTVELYESSY LASZLO DIPL PHYS
IPC: B60H1/30
Filed: 1983-01-04
Abstract: The streamlined surfaces of vehicles are suction surfaces in almost all cases, i.e.: if this surface is connected to the interior of the vehicle by means of a ventilation channel, this channel will suck air out of the vehicle and not blow it in. Thus, there is a large risk of sucking in exhaust gases from the same vehicle or from other vehicles. A large ventilator is necessary to overcome this suction effect. Nevertheless, in practice the amount of air is inadequate. According to the invention, the ventilation channel opens in the frontmost pressure zone but is provided with a flap which automatically (e.g. magnetically) remains closed at lower vehicle speeds. Thus, exhaust gases from the vehicle travelling ahead (e.g. in road traffic) are not taken in. While driving, a large amount of clear air flows in, specifically in a noiseless manner. Because of the excess pressure of the clean air, the vehicle's own exhaust gases do not pass into it under any circumstances.
