Patent DE-3337957-A1 (DE)
Title: Sheet leveller
Inventor: BENZ WILLI
IPC: B21D1/02
Filed: 1983-10-19
Abstract: A sheet leveller is provided with a plurality of upper and lower levelling rolls (13, 19), each of which is assigned a plurality of coaxially supported back-up rollers (12 and 20 respectively), the bearings of which can be adjusted vertically independently of the bearings of the back-up rollers assigned to the other levelling rolls. To improve the quality of levelling and avoid horizontal outward bending and bending vibrations of the levelling rolls (13, 19), the levelling rolls are shifted in a horizontal direction out of the vertical axial plane of the respectively assigned back-up rollers (12 and 20 respectively), the size (a) of this shift being determined from the normal forces (N1), which can be calculated at the sheet contact points (K1) of the levelling rolls (13, 19), and from the tangential forces (T), which can be calculated from the respective driving torques, to give minimum horizontal outward bending and bending vibrations of the levelling rolls (13, 19). <IMAGE>

Patent DE-3410523-A1 (DE)
Title: Filtration process and apparatus
Inventor: RATHJEN AXEL
IPC: B01D33/03
Filed: 1984-03-22
Abstract: A filtration process is proposed by the invention in which the suspension enters directly above the filter medium into a vessel under elevated pressure. The formation of a solid cake is prevented by the suspension stream and enables a high filtration efficiency as a result. The solid is conveyed by a pushing apparatus towards the pressure chamber, the solid moving with the same velocity at which the liquid is displaced from the pile as a result of the pressure difference present. Depending on the product conditions and filtration conditions, the solid can thus be dried, as in cake filtration, in contrast to pure cross-flow filtration.

Title: Electrical printed-circuit board having printed conductor tracks, especially for electric clocks
Inventor: DEUSCH HELMUT
IPC: G04C3/00
Filed: 1984-06-08
Abstract: The subject-matter of the invention is the production and construction of contacts which are fitted on conductor tracks of a printed-circuit board, especially for electric alarm clocks. The contacts are applied onto the relevant conductor track elements in the form of a metal solder, are soldered to said conductor track elements in a hot-air flow and are subsequently formed and calibrated by means of a pressing process. The use of a pure tin solder is proposed in order to produce the contacts. A moulding on the alarm-signal triggering spring is used directly as the mating contact. For this purpose, said moulding is produced from a stainless steel. It is provided for the contacts to be applied onto the printed-circuit board and to be formed thereon using, for example, computer-controlled automatic production units. The invention is intended for use in all contacts which may be used, for example, in an electric alarm clock, for example the alarm-signal triggering contact, light contact, alarm-signal selection switch etc.

Patent DE-3500872-A1 (DE)
Title: Centrifugal attraction
Inventor: BOEHME KARL
IPC: A63G1/48
Filed: 1985-01-12
Abstract: On the periphery of the essentially horizontal baseplate of a centrifugal attraction, which baseplate can be driven to rotate about a central axis, rails are secured which are aligned radially outwards and upwards and on which passenger carriers roll obliquely upwards from their lower position of rest when the baseplate, in operation, has reached a certain angular velocity. In their upper region, the rails are curved towards the central axis of the baseplate, so that the upward movement is braked. Furthermore, the baseplate is tiltable, as a result of which the inclination of the rails relative to the force of gravity changes constantly during a rotation of the baseplate and the passenger carriers travel upwards and downwards accordingly.

Patent DE-3515127-A1 (DE)
Inventor: BAIER PAUL WALTER
IPC: H04B1/713
Filed: 1985-04-26
Abstract: This apparatus uses as transmission medium the lines of electricity supply systems and allows simultaneous communication between a multiplicity of transmitters 1, 2, 3 and receivers 4, 5, 6, 7 without mutual interference. This multiple access apparatus is resistant against interference inherent in the mains, particularly against interference or attenuation which only relates to a part of the transmission frequency band. To achieve this, a multiplicity of discrete frequencies is used from a set of frequencies preferably above the audio frequency range. From this set, the instantaneous transmitting frequency of each transmitter is selected in accordance with a predetermined plan and in accordance with a timing pattern, common to all transmitters 1, 2, 3 and receivers 4, 5, 6, 7, which is preferably derived from the mains voltage frequency, and is varied in hops. Each transmitter 1, 2, 3 has its own pattern of variation, with the aid of which it can be selectively received by the receiver(s) 4, 5, 6, 7. <IMAGE>
