Title: Bath with an air bubble system
IPC: A61H33/02
Filed: 1987-12-16
Abstract: 1. Bath with an air bubble system. 2.1 Baths with air bubble systems have, under the bath tub, conduits for the supply of air, into which conduits, however, used water runs from the bath tub as soon as the fan is switched off. Cleaning and disinfection cause difficulties, especially in private installations. 2.2 In order to simplify this, the conduit (4) - viewed in the direction of flow of the air - is connected behind the last nozzle (3) to the tub outlet pipe (9), and between the last nozzle (3) and the opening into the tub outlet pipe (9) there is arranged, in the conduit (4), a shut-off valve (7) provided with a controllable actuating drive (7'). 2.3 A purposeful and controllable cleaning and disinfection is possible in a simple manner in this area. The arrangement is suitable for extension to an automatic system.  3. Fig. 1. <IMAGE>

Abstract: A device for identifying aircraft on a runway has a plurality 
of sensors (20, 21, 22, 23, 24, 25, 26) spaced apart along a 
runway. A reference sensor (21) is adapted to be operated by 
the nosewheel of an aircraft and several of the other sensors 
(22, 23, 24, 25, 26) is spaced apart from the reference sensor 
(21) at distances corresponding to known wheelbases of 
different aircraft. By detecting coincident signals from the 
reference sensor (21) and one of the other sensors (22, 23, 
24, 25, 26) it is possible to determine the wheelbase of the 
aircraft and thereby to determine which type of aircraft is 
travelling along the runway. By having a further sensor (20) 
situated before the other sensors, then by timing the interval 
between a signal from the further sensor (20) and the reference 
sensor (21), it is possible to obtain a value for the average 
speed of the aircraft along the runway.

Abstract: Bei der Dampferzeugung in Heizkraftwerken wird, um die 
Nachbehandlung von Rauchgasen zur Schadstoffreduktion zu 
vermeiden, die Wirbelschichttechnik eingesetzt. Dabei er­
folgt die Kohleverbrennung bei relativ niedrigen Tempera­
turen um 850° C, wobei in der Wirbelschicht (1) aus Kohle 
und Kalk kein bzw. kaum thermisches Stickoxid gebildet 
wird und sich bildendes SO₂ zu Kalziumsulfat umgesetzt 
wird. Durch die niedrigen Temperaturen ergibt sich 
jedoch ein höherer Ausstoß an CO, besonders im 
Teillastbetrieb. Um diesen zu reduzieren, wird dem Frei­
raum (3) über dem Wirbelbett (2) zusätzlich Wärme (4) zugeführt, wo­
durch eine gezielte Beeinflussung der Freiraumtemperatur 
unabhängig von der der Wirbelschicht erzielt und die Um­

Durch Drosselung (6) der dem Wirbelbett zuzuführenden Luft­
menge unter die stöchiometrisch erforderliche zusätzli­
che Luftzufuhr zum Freiraum unter gleichzeitiger Wärmezu­
fuhr kann weiterhin eine Reduzierung der NO x -Werte er­

A sole clamp (13) having a hold-down member (13') and a pedal element (13''), and also a hand-opening lever (15) are pivotably mounted about a transverse axis (14) in each case. The sole clamp (13) is biased by a release spring (16) into a closed position via a transmission (17, 18) having a deadpoint (26'). The sole clamp (13) can snap into an open position under the action of excessive vertical forces by moving through the deadpoint (26). The sole clamp (13) and the hand-opening lever (15) are pivotally mounted about the same transverse axis (14) which is arranged in the front region of the housing (12). Actuating abutments (19, 20) which cooperate with one another are provided at a radial distance from the transverse axis (14) and an opening moment is transmitted from the hand-opening lever (15 ) onto the sole clamp (13) via these actuating abutments.
