Patent DE-2852875-A1 (DE)
Title: Multi-spindle drill head for simultaneous boring - operates using drive tool shaft separate from drive gear
Inventor: WIELAND ALFRED
IPC: B23B39/16
Filed: 1978-12-07
Abstract: The multi-spindle drill head is used for simultaneous boring of several holes. It has a conical or cylindrical drive tool shaft and a drive gear, which can be automatically exchanged on change machine tools, especially numerically controlled operating centres with tool magazines, as on a normal tool used on such a machine. A drive tool shaft separate from the drive gear is used and this is connected with the drive gear so that it can move axially against spring loading. There is a spring in the bore of the drive tool shaft which accepts the gear shaft.

Title: Surface live examination appts. for body tissue etc. - measures nuclide density and both relaxation times using spin echo
Inventor: BERGMANN WILFRIED HELLMUTH DR
IPC: G01R33/3815
Filed: 1978-12-19
Abstract: The examination appts. is for live tissue, bones, organs, nerves and flowing blood for preventive purposes or to check the progress of therapeutic measures using the spin-echo technique. The sending and measuring coils of a core-spin-resonance apparatus enclose the area to be examined completely, and a detector and a computer to evaluate the measured values are included. The appts. has elements for measuring the nuclide density (with a magnetic core moment other than zero) in the selected examination volume, and for determining the spin-grid and spin-spin relaxation times, as well as the components of the diffusion tensor. Other elements measure the shortening of the spin-spin relaxation time, dependent on the flow state of blood in the examination volume. Both the working temperature of the measuring coil and that of the whole primary detection circuit are very low, preferably in the superconductivity range, and particularly in the temperature range of superfluid helium, e.g. below 1.85K.

Title: Inking mechanism for label printing machine - has inking rollers and ink container running in curved guide rails
Inventor: DASTING KLAUS
IPC: B65C11/02
Filed: 1980-06-30
Abstract: A printing machine for printing labels has the printing mechanism (22) attached to a lever (70) which is mounted between the side plates (58) of the machine frame. As the printing mechanism (22) is swung downwards by actuating the lever, the inking device (6) is forced to move along the curved guide rails (8) by means of projections (12). As the inking device (6) moves along the rails the inking roller (2) spreads ink on the type on the undersurface of the mechanism (27). The inking roller receives ink from the transfer roller (4) which dips into the ink in the receptacle formed in the device. Further movement of the printing mechanism pushes the inking device to one side and brings the inked type into contact with the labels (64) which are brought into position by the moving belt (66).
Patent DE-3025382-A1 (DE)
Title: Expansion cycle turbine or piston engine - works between superheat and saturation temperatures of high or low boiling liquid returning unused heat to cycle
Inventor: GENSWEIN ALFONS ING GRAD
IPC: F01K19/02
Filed: 1980-07-04
Abstract: The expansion engine cycle uses water, ammonia or another suitable medium and returns all the heat not converted into mechanical energy to the cycle. The high or low boiling point liquid is converted into super-heated vapour by external heat (Qu) and this vapour fed into an expansion engine, where it expands (I-II'), first at constant pressure and then adiabatically, to the saturation point of the medium. The saturated medium is then compressed (II'-2') to achieve complete condensation at constant expansion end pressure and the liquid medium, whilst at boiling point. The medium is then pumped (2'-1) to the superheater at the working pressure for the next cycle.
