Patent DE-3925442-A1 (DE)
Title: Restricting lines of shopping trolleys - involves two freely movable contours and coin operated locks
Inventor: FUCHS PETER
IPC: A47F10/04
Filed: 1989-08-01
Abstract: The device (1-5) for restricting rows of supermarket trolleys comprises two freely  movable contours which extend into the traffic area of a  trolley row and are hereby moved by the mobile trolleys in varied positions. The movable contours enter into active connection in one predetermined position so that one of the contours: produces a locking position which is released by the second contour and thus prevents the coupling position which is required to obtain the coin lock. USE/ADVANTAGE - The lengths of the trolley rows in a supermarket are kept to a manageable length which will not impede the surrounding area.

Title: Audibility improving system for emergency vehicle siren - uses car audio suppression unit activated by forward directed radio signal from approaching emergency vehicle
Inventor: SALOMON JOERG
IPC: G08G1/0965
Filed: 1990-06-09
Abstract: Emergency vehicles such as police cars, fire engines and ambulances are equipped with flashing lights and sirens to warn other road users of their approach, and to give them right of way. Motorists using car radio or hi-fi equipment can have a reduced ability to hear the sirens, resulting in delayed, hurried reactions.
