Patent DE-4140414-A1 (DE)
IPC: G01N21/76
Filed: 1991-12-07
Abstract: A process and device are disclosed for measuring and determining the fluorescence feedback of algae in order to determine the density and vitality of the algae by means of exciting light, the fluorescent radiation of the tested plants or biomass being detected. The object of the invention is to develop a process and device that allow the algae density, i.e. the light attenuation in a sample, and the vitality of the plants, to be determined in a short time, by simple means and in a relatively precise manner. At the same time, measurement of the delayed fluorescence and separate fluorescence measurement arrangements are to be totally dispensed with. For this purpose, a process of the above-mentioned type has the following steps: the algae are exposed to two differently timed light signals, one measurement light timed at a quick rhythm and a second x-Hz-light timed at a relatively slow rhythm; the detected signal is correlated with the timing signal of the measurement light, giving an intermediate signal; and the intermediate signal is correlated with the timing signal of the x-Hz-light, giving a calibratable result signal.

Abstract: The ultra-voilet disinfection of water and other fluids, in a flow channel, has a covering for the UV grid to form an enclosed flow channel with no free water surfaces. The under side of the covering is below the level of built-up water backing up from an overflow barrier so that, with all flow volumes and even when there is no flow, the UV radiation grid is within the water at all times. Pref. the covering for the UV radiation grid is a trough with an open top. The quartz covering tubes and the UV radiators are secured to the covering, in the required pattern, by mountings above the covering to give the quartz tubes and the UV radiators a free projection without additional components. The mountings are tubes or pedestals with guides for the inserted quartz covering tubes which can be a lip seal, oil-seal ring or guide ribs. The mounting can also be lip sealing at the covering for the grid, without tubes or pedestals, with an upper drilling in a flat strap or clip secured to the covering. A number of quartz covering tubes and their UV radiatiors are assembled in a unit by a moving mounting frame or other common mounting, in a row across the channel, to be installed and removed together. They can be assembled in a required configuration, for the fluid to flow round them, each with their own covering, with blind fittings for additional tubes to be inserted as required. USE/ADVANTAGE - The UV disinfection is for flows of sewage and the like, to destroy micro organisms without needing chlorine for bacteria and germ elimination. The system is particularly effective in disinfecting fluid flows, especially open channels.

Title: Controlling air-conditioning plant in car by closed loop - using comparator for cabin temp. and set point feeding air-conditioning controller as well as air distributor
Inventor: MOERSCH VOLKER
IPC: B60H1/00
Filed: 1992-05-02
Abstract: In a procedure for controlling the cabin temperature of a car with simultaneous control of the temperature of the air blown out from its air-conditioning system, the cabin temperature is measured and compared with a set point. An output signal from the temperature comparator goes to the temperature controller for the heating/cooling unit.

Patent DE-4230960-A1 (DE)
Inventor: LEUTNER WILFRIED
IPC: B62D5/22
Filed: 1992-09-16
Abstract: In a rack and pinion servo-assisted steering system, in particular for motor vehicles, a pinion (2) mounted in a steer housing (1) engages a rack (6). For servo-assisted steering, a servo-motor (11) is drivingly linked to the rack (6). The pinion (2) is swivelingly mounted in a fixed bearing (3) and in a loose bearing (4). The axis of a piston valve (26) arranged in the area of the loose bearing (4) is substantially perpendicular to the axis of the pinion (2). The loose bearing (4) is slidably guided perpendicularly to its axis only in the direction of the axis of the piston valve (26) in the steer housing (1). In this rack and pinion servo-assisted steering system, it is not the axial forces acting on the pinion (2) which are used to actuate the control valves, but the transverse forces. Actuation of the control valves is thus independent from the helix angle of the pinion teeth.
