Title: Method and arrangement for packaging paste-like foodstuffs in a multi-layer foodstuff case and a prepackaged long cylindrical enclosure arrangement for this method
Inventor: BECKER REINHOLD DR
IPC: B65B9/15
Filed: 1984-01-14
Abstract: In the method, tubular cases which have been gathered in long cylindrical enclosures are successively mounted on the filling tube of a filling machine and are simultaneously pulled away from the long cylindrical enclosure in question towards the filling tube aperture by the paste-like foodstuff coming out of the filling tube aperture. The long cylindrical enclosure forming an inner layer of the foodstuff case is the first to be mounted in each instance and the long cylindrical enclosure forming an outside layer of the foodstuff case is the last to be mounted in each case on the filling tube. The separated parts of the long cylindrical enclosures are drawn through the inside hole of the long cylindrical enclosures located in the direction of the filling tube aperture, and where appropriate also through the inner hole of the long cylindrical enclosure associated with the separated part itself in the direction of the filling tube aperture. An arrangement to implement this method and a long cylindrical enclosure arrangement which is prepackaged in a supporting case are also described.

Patent DE-3407438-A1 (DE)
Title: Heating installation with fossil fuels combined with heat pump operated by heat
Inventor: DIETRICH HANS-JUERGEN
IPC: F25B11/00
Filed: 1984-02-29
Abstract: The heating installation can be operated with all possible heat sources e.g. oil, gas, electricity, solid fuels, solar heat or other heat sources. The heat obtained is supplied to the heating system a) completely or b) only partially. The heat proportion then remaining free in case b) drives a turbine which in turn operates a heat pump installation. With it, heat can additionally be obtained from the surroundings. Consequently, it is possible to obtain more heating energy than primary energy is expended. As primary heat for the integrated heat pump, use can be made of any heat available in the required temperature range such as air heat, geothermal heat, water heat, solar heat or other heat. <IMAGE>
Patent DE-3407467-A1 (DE)
Title: Method for the sealed connection of two pipe ends
Inventor: ZOMBOR GABOR
IPC: F16L27/04
Filed: 1984-02-29
Abstract: A method for the sealed connection of two pipe ends having a relatively small and a relatively large diameter, respectively. The essential feature of the method is that the pipe end having the smaller diameter is inserted into the pipe end having the larger diameter, a material which ensures sealing is inserted between the pipe ends which are pushed into one another and a corrugation is produced in the pipe end having the smaller diameter, as a result of which a sealed bond is produced between the two pipe ends.
Patent DE-3414351-A1 (DE)
Title: Apparatus for the continuous dewatering of webs of fibre material
Inventor: KOCH HARALD DIPL ING
IPC: D21F3/10
Filed: 1984-04-16
Abstract: The invention relates to an apparatus for the dewatering of webs of fibre material, preferably webs of paper, cardboard and cellulose, the dewatering taking place in the region of the brattice and press section. The object is to provide an apparatus for the continuous dewatering of webs of fibre material, which makes it possible to utilise an optimum vacuum requirement according to the technological conditions of the webs of fibre material and thus to reduce the energy consumption to a minimum. This is achieved in that the suction zone is made variable by a variation of the suction surfaces, whilst the side walls limiting the suction box in the running direction are arranged adjustably in a circular, rectilinear or other direction.
Patent DE-3417217-A1 (DE)
Title: Functional sandwich laminate for producing ultra-lightweight windsurf boards and surf-boards and the like (all sandwich structures)
Inventor: CZENINGA MICHAEL DIPL ING
IPC: B32B7/022
Filed: 1984-05-10
Abstract: The invention relates to the specific production of a sandwich laminate which is more rigid in comparison to outer layers hitherto conventional, but is not heavier and may even be lighter, as the load-bearing outer skin for windsurf boards and surf-boards and the like, the production effort and material costs remaining in the economically viable range. The use of an outer skin of this type with increased rigidity permits very lightweight foam cores to be used. The problem of detachment of the outer layer from the foam core is solved by the installation of a valve. Initial prototypes (length approximately 3 m, width approximately 60 cm, volume approximately 140 l) weigh approximately 7.5 kg. Further weight reductions are possible by the use of materials which are known and can be produced but are not yet available. Furthermore, the invention represents a generally valid design principle.
Patent DE-3418719-A1 (DE)
Title: Turn-over plough having a swivelling support wheel
Inventor: BARLAGE BRUNO DIPL ING
IPC: A01B15/00
Filed: 1984-05-19
Abstract: The turn-over plough is equipped with a swivelling support wheel, the support-wheel carrier of which is mounted on the plough frame so as to be pivotable about a swivel axis extending horizontally and transversely to the working direction of the turn-over plough and, in each of the two working positions of the turn-over plough, respectively assumes a supporting position inclined obliquely rearwards from the swivel axis towards the support-wheel axis and limited by a stop. During the lifting and subsequent turning of the plough frame, the support-wheel carrier pivots forwards out of the supporting position past a vertical position and beyond the plough frame and an opposite vertical position. At the same time, there is a safety device which, in an intermediate phase after the conclusion of the turning movement of the plough frame and before the support wheel is placed on the ground, predetermines for the support-wheel carrier a safety position, in which the support-wheel axis is located behind the swivel axis in the direction of travel.

Title: Ink-ribbon cartridge arrangement in a printer of data output devices
Inventor: HOFMANN NORBERT
IPC: B41J35/04
Filed: 1984-07-05
Abstract: The invention relates to an arrangement of ink-ribbon cartridges in, for example, printers of data processing systems. The ink-ribbon cartridge is inserted in the device at an angle of, for example, 45 DEG so that larger spools can be used due to the larger cartridge depth which can be achieved and a larger supply of ink ribbon can be accommodated. At the same time, the device housing can be made smaller in the region of the ink-ribbon cartridge. The ink-ribbon cartridge itself has guide edges for the ink ribbon which ensure that the ink ribbon is disposed approximately perpendicular to the printing direction in the region of the printing point.

Title: Lung simulator and operating method therefor
Inventor: ROTHBALLER WOLFGANG DR
IPC: A61M16/00
Filed: 1984-07-24
Abstract: In a lung simulator for the simulation of different, predeterminable respiration patterns and for the simulation of mechanical lung properties the mobile wall parts of a chamber are designed to be unstretchable, so that a proportional change of the volume  DELTA V in the chamber (2) corresponds to a linear displacement of the mobile wall part (1) by about the amount  DELTA s. The pressure values DELTA P produced by the change in volume and the position X of the mobile wall part (1) are measured and used as control signals for a drive device (44). There is specified an operating method by which the lung simulator can be used for the simulation of active or passive respiration or of a combination of active and passive respiration. The equipment compliance  DELTA V/ DELTA P of the lung simulator, which can be changed electronically in a simple way, behaves linearly over a very wide range. <IMAGE>
