Patent DE-3117536-A1 (DE)
Title: Seed-coulter arrangement for seed drills or the like
Inventor: KIRCHBERGER FRANZ
IPC: A01C5/06
Filed: 1981-05-04
Abstract: The invention relates to a seed-coulter arrangement for seed drills or the like. The seed coulters of seed drills or such like appliances serve, during the sowing work, for digging in the ground furrows into which seeds are introduced via the seed coulters. The seed coulters are fastened to lever arms which are movable up and down and which are sprung individually and can be prestressed jointly via an adjusting device. As a result, the seed coulters can be pressed more or less firmly against the ground in dependence on the ground state. Each lever arm has hitherto been loaded appropriately by means of a helical spring and suspended in an articulated manner. However, this construction has only relatively short service times. The invention proposes that each lever arm (14) carrying a seed coulter (16) be arranged, via a torsion-spring element (21) made of elastomeric material, on a carrier shaft (12) for joint rotation with the latter, and that the carrier shaft be rotatable by means of an adjusting device for the selective fixing of the prestressing force with which the seed coulters are pressed against the ground. The principal sector of use of the invention is seed drills or such like seeding machines. <IMAGE>

Patent DE-3302150-A1 (DE)
Title: Heat exchanger and method for producing it
Inventor: THOMAE RUDOLF DIPL ING
IPC: F28F9/16
Filed: 1983-01-22
Abstract: The invention relates to heat exchangers, in particular for heating or cooling the engine of motor vehicles whose engines are liquid-cooled, consisting of a number of metallic fins(ribs) which contain openings, the rim of each opening being formed into a collar, and the collars, respectively assigned to one another and extending in the same direction, of adjacent fins, forming, after a multiplicity of gills have been assembled into a heat exchanger block, continuous pipelines which extend perpendicular to the fins. Such brazed heat exchanger blocks require a considerable technical outlay for their production, such as, e.g., brazing furnaces with a specially set up brazing atmosphere, or vacuum brazing devices. In accordance with the invention, these substantial disadvantages are avoided by setting over the outsides of the collars or in the insides of the collars rings which are made from preformed adhesive and which have a solid or dry elastic state at the processing temperature.
Patent DE-3302672-A1 (DE)
Title: Manual roller device for suitcases
Inventor: HUEBNER WILHELM
IPC: B62B5/00
Filed: 1983-01-27
Abstract: A manual roller device for suitcases only offers the traveller genuine relief and pleasant independence if the rollers are not, as in the past, located in the rear corner of the case but are under the bottom of the case, where they support the whole weight of the case, so that the traveller needs to do no more than gently guide the rolling suitcase. Such a rolling suitcase can be guided through the town over uneven roads, the case being very easily steered through crowds of people. It also facilitates movement in vehicles, since the passenger with a rolling suitcase can walk not only beside it but also in its tracks, so that fellow passengers can pass easily in the narrow gangways. A further great benefit of the rolling suitcase is that previously time-consuming circumstances which arise before and after the journey, when registering the case, delivering "door to door" or, for example, undergoing customs inspection are eliminated. The rolling suitcase thus provides a new, pleasant sensation of travel.
