Patent DE-19628735-A1 (DE)
Title: Optimum timing method for air change duration in heated room
Inventor: HOFFMANN HANS
IPC: F24F11/00
Filed: 1996-07-17
Abstract: The method involves measuring the relative air humidity in percentage of maximum water vapour capacity and air temperature in Celsius inside and outside. This is used to calculate the absolute air humidity as indicated for comparison with an optimised threshold value so that a recommended air change can be displayed. Subsequent to the air change and on approaching the comparison-based recommendation and above a preset threshold value, a recommended air change end point can thus be displayed. Carbon dioxide content in the room air may also be measured and indicated and the air change should be signalled on passing a threshold value. The room air smoke concentration may also be taken and an air change recommended above a preset threshold value. The same values as are used to give the recommended air changes are used to control automatic ventilation.
Patent DE-19629695-A1 (DE)
Title: Determining filling level of liquid with weak electrical conduction or limited viscosity
Inventor: RAMMNER RUDOLF J
IPC: G01F23/26
Filed: 1996-07-24
Abstract: The method for determining the filling level in a vessel involves using a metal coating representing a capacitor plate (C PL1), which is arranged at the vessel wall.  There is a capacitance (C PL2) at a runner to complete the sensor.  The runner is moved to and fro in the vessel, to vertically match the height of the liquid level.  This makes a direct connection across electrical components with a second pole of an AC generator.  Any capacitance variation causes an alteration of an electrical indication, in the form of a voltage or a current intensity shift in the circuit between the generator and sensor, which can be measured.  The alteration in the vertical position of the sensor, can be achieved using a rope pulley vertical drive or a threaded spindle and runner, driven respectively by geared motor drives.

Patent DE-19647587-A1 (DE)
Inventor: REITER FERDINAND
IPC: F02M61/16
Filed: 1996-11-18
Abstract: Fuel injection valves in which a fuel filter is inserted or pressed into the end of a fuel inlet manifold on the inlet side are already known per se. Interaction between the fuel filter and the through-passing fuel can however cause the filter to expand or contract. This can result in impaired sealing between the fuel filter and the inlet manifold. The novel fuel injection valve possesses a fuel inlet manifold (60) with a swelling inside (67) and slanting flank areas (80, 81). A holder section (50) of the fuel filter (61) is designed with a groove (69) which interacts with the swelling (67) to form a snap-in connection. According to the invention the groove (69) is so shaped that the holder section (50) of the fuel filter (61) is fitted closely to and seals the sloping flank areas (80,81) of the swelling (67).
