Title: Process for spreading spreading material by a fertilizer spreader and fertilizer spreader suitable for carrying out the process
Inventor: AEISSEN HEINZ DR
IPC: A01C15/18
Filed: 1982-09-29
Abstract: The invention relates to a process for spreading spreading material by a fertilizer spreader and to a suitable fertilizer spreader for carrying out the process, which has a spreading-material supply container and at least one jib-like spreading arm which distributes over the length of the spreading arm spreading material delivered from the supply container into the spreading arm and which feeds it to a spreading channel extending over the length of the spreading arm and having discharge slits, in front of which is arranged a spreading shaft which spreads the spreading material out of the discharge slits. The object on which the invention is based is, whilst ensuring a uniform discharge of the spreading material over the entire length of the spreading arm, to insure without any outlay in terms of construction that only as much spreading material as is necessary ever runs out of the supply container. According to the invention, excess spreading material accumulating in the region of the free end of the spreading arm and not spread out via the discharge slits by the spreading shaft is conveyed back via a return channel to that region of the spreading arm in which the delivery of the spreading material out of the supply container into the spreading arm takes place.

Title: Angling quill with mechanical drive
Inventor: TRIEFENBACH GEB MICHEL
IPC: A01K91/02
Filed: 1982-12-13
Abstract: For centuries, anglers have been using conventional, simple angling quills, the sole purpose of which is, depending on their type of design as a float, to carry bait of a greater or lesser weight. Anglers can cast these simple angling quills only as far away from the bank as they can apply strength and skill. Consequently, the distance between the place on the bank and the bait is set narrow natural limits. The invention adds to the conventional angling quill two torch batteries as an energy source, an electric motor, a propeller and a rudder to form an angling quill with mechanical drive which, by means of eyes and clips attached on the outside, can take the angling line and can propel any bait out onto the lake under its own force - instead of manual casting. A balance switch in the power supply circuit makes the motor and propeller switch on when the unit is in its horizontal position and makes the drive switch off completely when the unit is in its vertical position. A jerk on the angling line makes the inert bait weights slide out of the front clip (4). Once this load has been removed from the hollow front part, the relieved angling quill with mechanical drive can right itself and switch itself off by means of the balance switch (5). Consequently, during angling, it becomes a normal angling quill. With this novel angling quill with mechanical drive, in future the angler can reach catching areas many times further away than the distance to which he could previously cast manually, without changing his accustomed place on the bank. <IMAGE>

This design of diaphragms close to the film permits a large number of different film formats to be blocked out. In addition, the distance between patient and film is kept small.
Patent DE-3336248-A1 (DE)
Title: Double-shell oven
Inventor: LHOTA DIETER DIPL ING
IPC: F24B1/04
Filed: 1983-10-05
Abstract: The heat storage mass of the double-shell oven, which preferably consists of prefabricated parts, is divided into an inner storage core (3) which is a part of the inner shell (1), and an outer storage part, which is a part of the outer shell (2). A sheet-metal housing (4) receiving the storage core (3) acts as the partition between the two storage parts, and is enclosed by prefabricated wall plates (5,6) of the outer shell (2). The sheet-metal housing (4) then acts to distribute the heat delivered by the inner storage core (3), which is non-uniformly heated, and to transfer the heat uniformly to the outer storage part of the outer shell (2). The outer storage part is formed by a cast layer (10), especially of concrete, in which angle profiles (8) are cast for mounting on the sheet-metal housing (4). The radiant visible surface of the wall plates (5,6) of the outer shell (2) is designed to be tile-like or formed by tiles attached to the cast layer (10). The heat-storage capacity of each storage part is insufficient, the inner storage core (3) acting principally to protect the sheet-metal housing (4) from direct action by flame, so that thin metal sheets can be used. <IMAGE>

Title: Pneumatic conveying method for flowable bulk materials
Inventor: HAHN HORST DIPL ING
IPC: B65G53/20
Filed: 1984-02-29
Abstract: Flowable bulk materials are preferably transported using pneumatic conveying installations. As pneumatic transport in tubes requires a relatively large amount of energy, pneumatic flowing channels are frequently used in accordance with local conditions, in which flowing channels the bulk material which has been caused to flow is transported under the force of gravity like a liquid flowing downhill. In order to combine the advantages of this energy-saving system with the advantages of tube transport, flowing channels, preferably with a circular cross-section, and pneumatic vertical conveyors are combined in such a way that conveying sections are connected one behind the other to make individual sections, which each consist of a flowing tube and a pneumatic elevator. In order to maintain similar flow conditions, the cross-sections of the flowing tubes and/or the pneumatic elevators are enlarged and/or part of the stream of conveying air is guided out of the system at each conveying section. Uniform units can be used if an intermediate container is installed downstream of each conveying section and conveying is carried out intermittently from section to section.
