Patent DE-2824612-A1 (DE)
Title: Mounting ptfe fittings onto plastics or metal machine parts - e.g. padding rings onto axles by heating to increase inner diameter, slipping onto shaft, and cooling slowly
Inventor: HERZIG KARLHEINZ DIPL ING
IPC: B29C65/66
Filed: 1978-06-05
Abstract: In a process of mounting plastics elements onto structural components of any shape, the plastics elements are provided with bores or recesses fitting the outer dias. of the structural components. The process is suitable e.g. fitting protectors or connectors when plastics tooth wheels or tubes are to be fitted onto metal or plastics solid or hollow shafts. The elements are made of PTFE or other plastics with similar characteristics. The dia. of the bores or recesses is chosen so that it is slightly smaller, at room temp., than the outer dia. of the structural components. Before they are fitted, the elements are heated at a temp. lying above their processing temp. by a pre-determined amt. until the dia. of their bores or recesses is greater by some tenths of a mm than the outer dia. of the structural parts. They are mounted whilst still hot and allowed to cool gradually.

Title: Concrete-filled cast iron manhole cover - has internal reinforcing ribs only on ring collar to provide low weight
Inventor: EICHELMANN HORST DIPL ING
IPC: E02D29/14
Filed: 1978-08-02
Abstract: A cast iron dish is open at its top and has a spherical base free from internal ribs. The base has a constant thickness and a constant radius of curvature over the entire nominal dia. of the cover. The base is surrounded by and blends into a ring collar of about the same thickness as the base. The underside of the collar forms a thrust surface via which the cover rests on a shoulder. Stiffening ribs project radially inwards from the collar only over the transition zone between collar and base. The constant radius of curvature pref. extends over a min. 90% of the cover dia. The dish is filled with concrete. The weight of the iron dish can be reduced to save material costs, without impairing the strength required for the dish.

Title: Pulse suppressor for spark erosion machine - has output signal of voltage comparator transmitted to switch via memory
Inventor: WISKER JUERGEN
IPC: B23H1/02
Filed: 1978-09-25
Abstract: The pulse suppressor is for spark erosion machines with an electrical pulse generator connected to the main gap. This also has a pulse detector to identify non-effective pulses by controlling a switch to switch off the pulse voltage fed to the gap when necessary. The pulse detector has a voltage compactor which, on passing through a given voltage level, generates a pulse suppressing switch voltage. The output signal of the voltage compactor is transmitted to the switch device by means of a memory fed by the output signal. The memory content is transmitted at intervals to the switch device.

Title: Chuck for end milling cutter - has screwed retaining sleeve with inclined flange face to prevent distortion of chuck body
Inventor: SCHNEIDER BERTHOLD
IPC: B23B31/20
Filed: 1978-10-11

Title: Voltage switching sequencer for power supply transformer stations - uses individual switchgear simulation and rated switchgear model with test runs providing acceptable switching sequence
Inventor: HECHT SIEGFRIED DIPL ING
IPC: H02H11/00
Filed: 1978-12-07
Abstract: Voltage switching sequences in transformer stations of a power grid are carried out by forming a switching model for the actually available individual switching stations of each transformer station, using an imaginary standardised model, applicable to all switching stations. This is carried out in such manner that all switchgear elements, such as isolators, power circuit breakers and earth switching breakers, are used as variable switching elements. All switchgear elements, not available in the actual switching station, are used as contact switchgear. This model, fitting the actual switching station is subjected sequentially to preprogrammed, standardised switching sequences in test run. These sequences are applicable to different switching stations. The switching runs are used for finding empirically a suitable switching sequence, which is the put into operation. Preferably each switching sequence starts with a given base position of the individual switchgear elements. The best corresponding base position is selected from several possibles.
