Patent DE-2140895-A1 (DE)
Title: Wire coiling machine coiling disk - with replaceable v-groove rings
Inventor: SCHAUHOFF KARL-FRIEDRICH
IPC: B21C47/14
Filed: 1971-08-14
Abstract: The vertical coiling wheel for use with wire coiling machines comprises a V-shaped groove made up from two identical replaceable interchangeable rings. Each of these has one flat surface and one reverse surface with an outwards slanting portion. When placed on top of each other, the V-groove is made up of the flat surface of one ring and the slanting surface of the other, the position of the rings being reversible so that each ring is used twice before being worn out. The method saves the scrapping of the complete wheel and extends the useful life of the rings. The coiling wheels is used in conjunction with coiling machines for still and/or thick wires, which require bending prior to coiling.

Title: Temperature sensing to determine machine performance - has machine maximum operative condition described by preselected temperature levels
Inventor: HOLVOECK PETER DIPL ING
IPC: G05D23/24
Filed: 1973-12-10
Abstract: The maximum operating condition of a machine or process can often be described by the state of various temperature sensors. A reference input unit is used to select a specific output stage, e.g. power level. Each temperature sensor output is converted and is fed to a signal generator. The signal generator outputs are coupled to a selector circuit that is regulated by a reference input. Once a particular operating condition is fixed the reference input together with the reference input selector permits the required temperature sensor levels to be set for various machine functions.

Title: Double field wing driving mirror - produced by applying glass wedge over outer half of normal mirror
Inventor: MARHAUER FRIEDRICH
IPC: B60R1/08
