Patent DE-2408811-A1 (DE)
Title: Cattle-stall yoke has two uprights - with hinged top sections connected by opening and closure devices, and chain attached bottom sections
Inventor: LEVERS BERNHARD
IPC: A01K1/062
Filed: 1974-02-23
Abstract: The yoke consists of two uprights each of which is hinged at the same heights as the other to form two longer top sections and two shorter bottom sections. The shorter sections are hinged together and may have cables or chains joining them to the stall. The top ends of the longer sections have guide-sleeves, each of which has a stop-piece. A cable line, running over guide rollers, touches the guide-sleeves, and opens the yoke. The adjustable resistance keeping the uprights in an open position has a pivot axle on which two levers are mounted. The two uprights are joined by a device which stretches when the uprights are pulled upwards and outwards by operating the cable line.

Title: Magnetic recording of AC voltage signals - with higher effective signal amplitude in magnetic coating
Inventor: AUER RAINER
IPC: G11B5/00
Filed: 1974-03-11
Abstract: An a.c. premagnetizing signal is superimposed on the effective signal to be recorded. The amplitude of the sum of the two signals is a multiple of the modulability of the recording medium, and the sum signal is fed to a double-ended current limiter. The latter limits the sum signal amplitude to a value slightly exceeding the range of modulation of the recording medium. The signal is then fed to a recording head, whereby the frequency of the premagnetizing signal is such that its wavelength is substantially shorter than the gap width in the head.

Title: Thermionic converter which transforms thermal into electrical energy - uses heated conical metal conductor in divergent magnetic field
IPC: H01J45/00
Filed: 1974-08-01
Abstract: The thermionic converter converts thermal into electrical energy, and uses a truncated conical metal conductor to generates an electric potential drop in a heated electrical conductor. The conical conductor lies in a magnetic field that diverges along the axis of the converter. Free electrons are driven along this field by the kinetic energy obtained thermally. The conical conductor is enclosed in a thermally insulating housing and heated by either fossil or nuclear fuels. The divergent magnetic field is generated by an electromagnet with suitably shaped poles. The output voltage is obtained via a thermally isolated transformer.

Title: Polygonal wound packaging sleeve - is foldable along long edges and collapsible over its cross section using longitudinal grooves
Inventor: SAUL FRANZ J
IPC: B31C11/02
Filed: 1974-05-20
Abstract: The spirally wound packaging sleeve has a polygonal cross section and is foldable along its long edges, thus being collapsible over its cross section into a flat configuration. This is enabled by longitudinal grooves embossed either into its inner or outer corners of its longitudinal edges.

Title: Wind powered turbine driving electric generator - is mounted at throat of inlet cone surrounded by outer cone
Inventor: HARFF ANTON M
IPC: F03D1/04
Filed: 1975-04-25
Abstract: A wind driven axial flow turbine is directly coupled to an electrical generator. The turbine is arranged so that the first row of blades fits in the narrow end opening of a convergent conical inlet piece (A). This increases the wind velocity onto the turbine and thereby increases the output and efficiency of the turbine. A second cone (B) surrounds the first cone and has its narrow end opening with a small annular gap round the last row of blades. This produces an underpressure at the exit of the turbine which increases the output and efficiency further. A discharge cone (C) tapers away from the narrow end of the outer inlet cone (B) and aids efficiency by giving a turbulent free discharge wake.
