Patent DE-3919297-A1 (DE)
Title: Combining washing of hydrocarbon from waste air - with bio-filtration of washings
Inventor: SEIDLER MANFRED DIPL ING
IPC: B01D53/85
Filed: 1989-06-13
Abstract: Hydrocarbons present in waste air, e.g. from industrial processes, are largely absorbed by washing with water. The  washing water, small in vol. compared with the air it has purified, is conveyed by piping to a solid bed biofilter through which the water trickles. The dissolved hydrocarbons are biochemically broken down, while the bed is maintained at the necessary moisture level for operation. ADVANTAGE - Biofilter can be located at any suitable  position, possibly a considerable distance from the washing plant.

Title: Compost and humus prodn. from organic waste - by multistage fermentation with periodic removal and addn. of liq. phase to control process
Inventor: MEIER HEINZ
IPC: C05F3/00
Filed: 1989-10-28
Abstract: Method of increasing the microbial conversion of agricultural, natural or industrial organic waste to useful products comprises first heating liq. waste and opt. solid waste, while  retaining the pumpability to 15-20 deg.C and mixing 0.1-1.5, esp.  1 wt% of solid pre-rotted material (pref. after 8-10 days rotting).  1-3 wt% of a tissue which acts as C source is then mixed in to produce a porous prod. The mixt. is passed to a treatment vessel while maintaining its temp. and the solid phase is comminuted to give a homogeneous dispersion. Air is passed i to aid microbial growth.  The prod.  is passed to 2 heated vessels where it is stored for 3 days.  The liq. phase is drawn off from the floating solid phase and is transferred to a storage vessel. The solid phase is mixed with 1-3% of a different biomass, transferred to a fermentation tank and stored for 3 days.  Liq. efflient is opt. removed and recycled to a storage tank (this stage may be omitted).  The solid phase is then withdrawn and allowed to ferment on 3-4 fermentation phases of a level liq.  impermeabeable fermentation surface for 3-5 days while controlling the temp. by addn. of liq. from the storage tank in an amt. of 60-75 wt% based on total mixt.  The temp. is kept at 30-55 deg.C for the first 5 fermentations, and at 60-70 deg.C for the remainder.  This is achieved without adding liq. phase but by opt. adding H2O. The prod. from the last stages is removed for use as compost and/or humus. The process is repeated periodically.

Title: Hand guided floor sanding machine -  has sanding drum with free-wheel bearing mounted in oscillating frame to produce intermittent drum rotation
Inventor: LUSTIG LEO
IPC: B24B23/03
Filed: 1990-10-19
Abstract: The sanding drum (12) is mounted on an axle (axis 20) at the end of a frame (28) which is attached by rubber mountings (30,32) to the housing of the machine. A motor in the housing has an eccentric drive onto the frame, giving rise to a circular motion (40) of the frame and drum axis in the horizontal plane. Because one of the bearings for the drum is a free-wheel, the drum rolls over the work surface (14) when the axis (20) moves to the left and skids over the surface when the axis moves to the right, thus producing a sanding action and intermittently feeding the drum periphery past the surface.

Title: Motor vehicle impact detection method for activating occupant safety system - measuring acceleration and deceleration, integrating, subtracting previous speed value and comparing with threshold
Inventor: DREXLER JOHANNES DIPL ING
IPC: B60R21/01
Filed: 1991-05-31
Abstract: The method of detecting motor vehicle impacts involves using a circuit in which sensors detect accelerations and decelerations to produce signals which are evaluated.
