Title: Roof mounted stable ventilator - has structure with sloping internal guides and wind deflectors forming mixing chambers for swirling flow
Inventor: WALSER ALEXANDER
IPC: A01K1/00
Filed: 1980-05-10
Abstract: The ventilation system for a stable uses a roof mounted ventilator designed to ensure a good extraction of stable air by generating an upward draught under widely varying atmospheric conditions. At the top of the sloping roof is a central opening between side guides (DPL) which slope inwards to narrow the opening at the top. Smaller guides (F) which slope outwards in the opposite direction are mounted adjacent to their top edges. The induced draught is then guided by adjustable flaps (S) to travel sideways resulting in a swirling action under a sloping cover above the gap, for discharge through outer vents in an upper housing with sloping sides (W) forming wind deflectors. These have a narrow opening underneath to allow air to enter and mix with the swirling flow inside their mixing chambers (1).

Patent DE-3112122-A1 (DE)
Title: Method and device for vehicle diagnosis
Inventor: MAURER FRANZ DR ING
IPC: G01M15/12
Filed: 1981-03-27
Abstract: A method and a device are proposed for vehicle diagnosis, in which the cross-correlation technique is applied. Typical noises of prime movers, which occur with specific faults in the latter, are stored in a memory unit. The noises of the prime mover to be tested are picked up by a microphone. It is established by cross-correlation whether the stored fault noises are present in the recorded noise spectrum of the prime mover. The delay time between the two signal characteristics which is required for the correlation can be varied. It is established by an evaluation circuit whether the fault noise is being emitted by the mover and under which phase angle this noise occurs. This permits selective maintenance of the mover, since a pulse which occurs can be detected right in the early stage of its occurrence. <IMAGE>

Patent DE-3132874-A1 (DE)
Title: Stochastic RMS measurement
Inventor: HILBERG WOLFGANG DR ING
IPC: G01R19/02
Filed: 1981-08-20
Abstract: To measure the RMS value of a voltage, the root of its square mean must be determined. The operations required for this are carried out using analog computing techniques in conventional measuring instruments and can therefore only be applied to low-frequency voltages. In the circuit according to the invention, these operations are applied to stochastically selected samples of the voltage in a microcomputer. This circuit is distinguished by the fact that its processing speed is independent of the signal frequency. The cut-off frequency is thus only determined by the sampling circuit and can be increased further by simple means.

Title: Method for tightening screw connections using yield point control
Inventor: MAYER EBERHARD DR ING
IPC: G01L3/10
Filed: 1981-10-31
Abstract: For the highly accurate tightening of screw connections, use is made of tightening methods using yield point control to avoid variations due to different frictional factors. However, unevennesses in the torque characteristic caused by mechanical vibrations of the screw system or by the inevitable slowing-down of the screwing tool as a result of its inertia and the delayed execution of the switching-off command are not considered. By appropriate selection of the switching-off criteria, it is possible on the one hand largely to compensate for the variation of the slowing-down time and on the other hand also reliably to recognise certain faults in the connection. An evaluation of the measured variables which dies out exponentially independently of time makes it possible, on the one hand, effectively to suppress the ever-present rotary vibrations and interfering impulses and hence avoid premature faulty switching-off without having to accept a long delay time. A connection method suitable for this makes it possible to carry out the theoretically made demands.
