Title: Fitting for the do-it-yourself mounting of vertical blinds
Inventor: MOSSENTA PIERLUIGI
IPC: E06B9/36
Filed: 1982-04-29
Abstract: What is described is a fitting for the do-it-yourself mounting of vertical blinds, which is characterised in relation to conventional blinds of this type by a plurality of simplifications which are aimed at making it possible to mount the fitting without employing specially trained craftsmen. For this purpose, the guide rail is snapped onto clamping plates which are first to be screwed to the ceiling and on which the guide rail is automatically oriented even when mounting is somewhat out of alignment. Furthermore, complicated cord pulls are replaced by a simple hand linkage, and the textile webs are held by slat holders in the flat end clips which engage into holes punched in the textile web in the manner of simple file holes. Finally, the end caps in front of the end faces of the clips are prevented from being pulled off no longer positively, but non-positively, so that the end caps can be pulled off again in a simple way. All these features have been provided on the fitting in order to make do-it-yourself mounting possible even for a person with little experience of manual work.
Patent DE-3216725-A1 (DE)
Title: Spraying device for cleaning and care of teeth and gums
Inventor: BEHA ENGELBERT
IPC: A61C1/00
Filed: 1982-05-05
Abstract: A spraying device (1) has a supply vessel (2), a pump (3) and a spray nozzle (7). Furthermore, the pump is provided with an adjustment device (9) for adjustment of the spraying intensity. The pump (3) is designed as a reciprocating pump and has an inlet valve (4) controlled as a function of the pressure, and an outlet valve (5). The adjustment device (9) cooperates with the inlet valve (11). It has essentially a stop (14) by means of which the valve body (11) of the inlet valve (4) can be held in different, slightly open positions during the working stroke of the pump (3) during which the inlet valve (4) would intrinsically be closed. Thus, depending on the setting of the stop (14), a backflow opening in the direction of the supply vessel (2) remains in the region of the inlet valve (4), so that some of the conveying volume present in the pump chamber (10) flows back, as a result of which the conveying quantity and hence the spraying intensity of the liquid emerging from the spray nozzle (7) is correspondingly reduced. <IMAGE>

Title: Sail arrangement for a windsurfing board
Inventor: RADEBOLDT JOERG
IPC: B63B35/79
Filed: 1982-05-10
Abstract: A special sail for a windsurfing board which is designed and arranged in such a way that the sail area can be reduced on the water so that the user, if he becomes exhausted or if the wind strength increases beyond his ability, can start sailing again with substantially reduced sail area (the smaller sail area facilitates the start), can continue sailing and can still reach his starting point or destination instead of drifting helplessly with his windsurfing board on the water and as a result getting into a perilous situation in the extreme case or posing a hazard to shipping. The sail is attached in a vertically adjustable manner to a separate sail holder which is designed as a sliding device and sits on the mast pocket, specifically with its luff by means of a weatherstrip so that the sail can be lowered relative to the mast, the sail area presented as working area to the wind being reduced owing to the fact that the lower part of the sail, which has come with its luff out of the sliding device, is now removed by being pulled out of its holder at the foot of the base sail, which holder is likewise designed as a sliding device. Provided for the removed foot part is a special quiver-like pocket which is attached in the lower area of the mast pocket and receives the foot part.

Filed: 1982-05-24
Abstract: The invention relates to a nationwide warning installation on federal motorways and long-distance roads, which, by means of flashing lights attached to emergency telephones, signposts or road signs, warns the driver of obstacles and hazards of whatever kind, and hence induces him to drive particularly carefully and more slowly. Costly signal gantries and the like, such as already exist, thus become superfluous. The warning installation can be made operational or switched off by radio, by highway maintenance departments, municipal authorities or the police, from their vehicles if appropriate. As a result of the early warning, the number of serious accidents is reduced to a minimum.

Patent DE-3241846-A1 (DE)
Title: Protective device against break-throughs, for example to a lock
Inventor: OPFERKUCH WILHELM
IPC: E05B65/00
Filed: 1982-11-12
Abstract: A protective device against break-throughs to an object to be protected, for example a lock, an alarm system or the like, has a protective plate, preferably made of material difficult to cut, and a release loaded by this. The protective plate is movable transversely to its extension and, in the event of such a movement, can actuate the release. Such a movement occurs either as a result of a displacement of the plate counter to the forces of springs in the event of a mechanical attack or as a result of particular expansions of regions of the plate in the event of an attack with a thermal tool. The release can either itself form a barrier, or free barriers which then additionally form obstacles, actuate alarm systems, etc.
