Patent DE-2247655-A1 (DE)
Title: Controlling knitting machine storage drums - drums stop automatically when machine stops
Inventor: TELLERMAN EDWARD M
IPC: D04B15/48
Filed: 1972-09-28
Abstract: In a knitting machine having at least one rotatable storage drum on which yarn is wound to be axially unwound from the drum for feeding to the knitting needles, there is a generator driven by the machine drive motor which passes current through a solenoid to close and keep closed a switch beamed to a closed position. When the knitting machine stops, the current through the solenoid stops and the storage drum driving circuit is open to stop the storage drums. Twist is not imparted to the knit yarn when the knitting machine is stopped.

Title: Water cooled power cable with paper insulation - has insulation dried by evacuation and passing steam through inner tubular conductor
Inventor: FRIESENHAGEN ENGELBERT
IPC: H01B13/22
Filed: 1973-07-06
Abstract: The water cooled power cable consists of an inner tubular conductor through which the cooling water flows, paper insulation around this inner conductor, a screening sleeve over this insulation and an outer tube enclosing the cable assembly. The cable is manufactured by pulling the screening sleeve into the outer tube, or by pressing the tube over the sleeve, then sealing the outer tube, and finally evacuating it, whilst simultaneously drying the cable by passing steam through the inner tube. Evacuation reduces production costs caused by expensive drying equipment.

Patent DE-2359164-A1 (DE)
Title: Constructional machines bearing seal - has rubber ring carried by horizontal leg of annular seal to reduce wear
Inventor: BANGERT HANS
IPC: F16J15/3208
Filed: 1973-11-28
Abstract: The protection is applied to slide bearings operating in adverse conditions and ensures that the ingress of dirt to the mating parts is suppressed. The grease is fed to the bearing bush through a central bore of the shaft and reaches a recess for further distribution. The bush fixed in its housing is shorter than the latter so that the left out spaces are used for the L-shaped seal ring facing seals. The rubber O-rings are set on the legs of a ring and thus do not come into a direct contact with the shaft to eliminate wear.
Patent DE-2410546-A1 (DE)
Title: Rotor for electric machine - has screws transferring centrifugal force to poles via different-length elastic elements
Inventor: STARCEVIC MIHAILO DIPL ING
IPC: H02K3/52
Filed: 1974-03-06
Abstract: The rotor, for an electric machine, has each of its poles carrying part of the overhang load and the centrifugal forces are transmitted by screws to the pole pieces. The screws are constructed so that the expansion resulting in the centrifugal force tending to separate the screws from the rotor varies over the length of the poles according to the bending of the elastic line on the pole shoes. The screws have expansion sections whose lengths vary along the length of the poles according to the required expansion. To give different expansions, the screws are made of materials having different elastic constants.
Patent DE-2425744-A1 (DE)
Title: Inner tube during vulcanising is partly flattened - but has rounded edges to prevent forming of weak lines
Inventor: KOSANKE JOHANNES
IPC: B29D23/24
Filed: 1974-05-28
Abstract: A method of vulcanising inner tubes of automobile tyres consists of holding the endless, annular tube blank with its walls flattened together; at the edge regions of the flattened blank tube, the walls are spaced slightly apart so that there is a curve rather than a sharp kink in this region. Pref., the tube may be initially partially filled with air, another gas mixt. or a pressurised fluid before vulcanisation is commenced; as the tube is flattened, this fluid is squeezed into the edge regions. During the initial part of the flattening the tube may be open to atmosphere, after which it is closed and finally flattened for vulcanising. For any kind of inner tube, but esp. for reinforced inner tubes for safety tyres, where the reinforcing inlay is esp. susceptible to damage by kinking. The method prevents the forming of weak lines along the tube.
