Patent DE-2735270-A1 (DE)
Title: Typewriter with automatic correcting function - in which depression of correcting key stores corrects function or merely tensions spring
Inventor: DROGI DIETER
IPC: B41J29/36
Filed: 1977-08-05
Abstract: Typwriter has a correcting key(3) which, when depressed, sets a back spacing and a correcting function. The actual correction is performed by repeat depression of the erroneously depressed character key. The backspacing of the carriage and raising of the correcting ribbon are then carried out before the character is actually typed. If the correcting key itself has been depressed erroneously, it is merely necessary to depress e.g. the spacer bar to cancel the stored correcting functions. Partial depression of the correcting key with a sudden impact merely results in tensioning of springs(123, 103) which connect that key to the mechanism.

Title: Trailer with automatic loading and unloading system - has bundles positioned automatically on loading platforms inside trailer
Inventor: GUALDI GIUSEPPE
IPC: A01D90/08
Filed: 1977-08-08
Abstract: The trailer comprises a collector which in the loading phase lifts the bundles on by one from the ground up to a position where they are aligned are behind the other.

In the loading phase the conveyor nearest to the collector is powdered whilst the other is left free but in the unloading phase both conveyors are powered. When aligned the bundles are pushed onto a loading platform positioned inside the trailer. At the start of loading all the loading platforms are stacked t the bottom of the trailer and as each one is filled it is raised towards the top of the trailer.

Title: Deep-drawn mould for accurately casting small articles - using heat-plasticised foils mounted in holding rings and placed over model casting
Inventor: MERAK SEVKET
IPC: A61C5/77
Filed: 1977-11-30
Abstract: Deep-drawing tool for mfr. of small casting moulds used in prodn. of dimensionally highly accurate mouldings such as dental crowns or bridges, and mountings for (semi)-precious stones, has a lever fastened centrally upon the device, carrying a vertical cylinder in its middle, upon which ring mounts for holding deep-drawable foil are placed. In its starting poisiton the cylinder bears upon a 12-volt heater, with the foil(s) held in the mounts, on top of it. When the heater is switched on the foils are softened very rapidly (within seconds). Opposite the heater, there is a vacuum-generating station in which the model from which the moulds are to be shaped (e.g. a model of a tooth stump) is located. By turning the lever about 180 degrees the cylinder is passed to the vacuum station and the plasticised foil contacts the model. Vacuum is then applied whereby the foil is deep-drawn about the model. The lever is then pivoted back and the deep-drawn prod. cooled by compressed air. The device is then ready for renewed operation.

Title: Solids separating screen for slurry - has two compartments fed with slurry-ore and slurry-rock mixtures
Inventor: KASTIN REINER
IPC: B01D35/28
Filed: 1977-12-12
Abstract: In separating ores from rocks, a slurry of high specific gravity is used so that non-metallic particles float on the surface and the ore particles sink to the floor of the tank. The separation of the slurry from the ore and rock particles is done by using a screen with its upper surface divided by a wall (26) into two compartments (28, 30). The mixture of slurry and ore is fed into one compartment (30). The slurry from both sections (28, 30) is then collected in the common tank (10).
Patent DE-2758469-A1 (DE)
Inventor: ZUMSTEG HORST
IPC: B65D17/40
Filed: 1977-12-28
Abstract: The container comprises a lid (1) made of a foil material, such as aluminium foil, which lid has a circumferential fold (3) which is formed by deep-drawing and forms tear-off lines in the region of its lateral edges, along which tear-off lines the circumferential fold (3) can be torn off by means of a tab (10). The intention is for the lid of the container to be able to be torn off automatically along a predetermined path by means of the tab. The tab forms a separate part and is attached to the lid material between the tear-off lines directly on the fold (3). The connection force between the tab and the lid should exceed the tearing force. For this purpose, the connection can be made by means of hot-crosslinking adhesive or by means of ultrasound. The tearing line can be formed as a line of weakness, in which case the tab can consist of flexible material. The tab can also be of rigid construction and have a cutting edge by means of which the tearing line is formed by setting the rigid tab upright. <IMAGE>
