Title: Rewind block for cassette film - includes blocking tab stamped in centre of leader
Inventor: MAIER ALBERT
IPC: G03C3/00
Filed: 1978-11-14
Abstract: A cassette loading film is used in a camera. The film leader is provided with a stamped tag (6) in the centre of the film strip to form a safety catch to prevent the film from being fully wound back into the cassette. The tag protrudes out of the plane of the film and jams into the cassette slot. The modification can be applied to conventional cassette films. It prevents fully rewinding into the cassette so that subsequent film processing does not have to open the cassette to retrieve the film, it is simply pulled out by its leader.

Title: Telephone answering machine with solid state memory - has auxiliary circuit for displaying memory utilisation
Inventor: MOELLEKEN HEINZ ING GRAD
IPC: H04M1/65
Filed: 1978-12-16
Abstract: The circuit provides a built in check on the message stored in the solid state memory in order to verify compliance with statutory regulations concerning operation of telephone answering machines. The memory is connected via a digital to analog converter and an integrator to a display unit. This gives the extent to which the memory is filled in relation to elapsed time. It is thus of value when recording the message which is to be relayed to an incoming call. It saves having to check the recording with a stop watch. The display can also be used to indicate the extent to which a message has been replayed. Typically the display comprises an array of light emitting diodes which come on in a sequence depending on memory content and time.

Title: Alarm system preventing vehicle driver from entering wrong lane - using correct direction detector to trigger warning system when incorrect lane is approached
Inventor: WICKERT GERHARD PROF DR ING
IPC: G08G1/07
Filed: 1979-01-11
Abstract: The traffic control system is for replacement or augmentation of the existing horizontal and vertical road marking, without having the disadvantage of being obstructed by fog, heavy rain, or snow. The system contain two control points which maintain the correct travel direction and which trigger a warning alarm if an incorrect lane is entered. The correct direction is maintained by optical and/or mechanical and/or acoustic elements. These elements may be provided on one or several points of the roadway. The warning alarm is pref. triggered automatically and at such a distance as to prevent entering into a wrong lane. The triggering of the warning alarm may be simultaneously transmitted to monitoring stations. The alarm triggering may also initiate the warning signs along the route in question.

Title: Movable rail hung partition panels - have force deflecting units extensible in sealing battens engaging ceiling or floor
Inventor: SCHWARZ HEINZ
IPC: E04B2/74
Filed: 1979-05-26
Abstract: Travelling panels suspended on a rail are sealed against extensible sealing battens on the ceiling and/or floor, in a partition wall. Inside the panels there is a link-rod system, acting with an activating medium to adjust the battens and to press panels' vertical abutting edges together. A mechanism (30, 31, 33) for changing the direction of force is mounted in one or both sealing battens (17, 18) on a panel (10, 11). When battens are extended, this comes into contact with ceiling (19) or floor (20), to exert a force constituent in the vertical abutting edge direction, on the panel. Simple construction provides effective coupling and release of adjacent partition panels.
