Title: Three-phase static inverter pair with output transformer - has common yoke for twelve windings to reduce magnetic losses
Inventor: HEINICKE HARALD
IPC: H02M7/49
Filed: 1974-03-29
Abstract: The three-phase statis inverter pair has both inverters supplied in parallel from the smoothed output of a single battery and controlled from the same control unit. The phase shifted outputs of the inverters are passed to an output transformer. The transformer consists of an iron yoke shaped like two figure 8s side by side and has two groups of six windings wound around its six limbs i.e. two groups of three inputs and one group of three outputs---the latter leading to the a.c. load. The outputs of one inverter are connected to the transformer winding such that they are displaced by 120 w.r.t. the output connections of the other inverters.

Title: Muscle powered road vehicle - has swing arm movement transmitted to back axle by closed chain drive
Inventor: HERBST WOLFGANG DR ING
IPC: B62M1/16
Filed: 1974-05-30
Abstract: The muscle-powered road vehicle has the movement of a swing arm (A) transmitted to the back axle (D) by means of a closed chain drive. The chain drive can remain so unchanged in length that it is deflected about two rollers (B,C) at the focal points (2,3) of an ellipse. The chain drive in the middle position is fixed to the swing arm at the apex point of the ellipse, and the effective length of the swing arm between (1 and 4) is equal to the radius of curvature at the apex point (1) of the ellipse. The plane of movement of the roller seat drops away backwards in the direction of travel.

Title: Distributor frame made of extruded profiles - consists of four separate sections joined by insertable corner couplers
Inventor: MAIS ADOLF ROLF
IPC: F16B7/04
Filed: 1974-05-29
Abstract: The frame is intended for distribution boards. The frame side walls are provided with ribs and slots for the retention of the coma couplers, held in the slots with little clearance. The insertion ends of the couplers are so shaped that, when inserted, an internal tension is generated in them, so that the coupler sharp edges are pressed into special ribs and grip them. This is facilitated by induction heating of the couplers when the frame is assembled. The wall sections are preferably in the form of hollow chamber walls and the slots and ribs are provided closely under their surface.

Title: Twisting efficiency measurement in frictional false twist texturing - by metering wheel similar to and coaxial with twisters
Inventor: COLL-TORTOSA LIBERTO
IPC: D02G1/08
Filed: 1975-07-26
Abstract: Device for measuring the degree of twist imparted to a yarn during the texturing process by a frictional twister having a driving shaft on which a frictional twisting disc is secured has a metering disc free to rotate on bearings. This is maintained in contact with the yarn and is turned by it at the circumferential speed with which the yarn rotates, so that the speed of rotation of the metering disc can be compared with that of the disc imparting the frictional twist. The matering disc rotates coaxially with the shaft and is supported by it directly or indirectly through bearings. The point of contact between the yarn and the metering disc is on the zone in which the frictional false twist is imparted. The compact device can be installed at each twisting point for continuously and accurately measuring the circumferential speed of the yarn.

Title: Torque or winding squirrel cage motor - has rotor with parallel groups of high conductivity rods with varying resistance PTCs
Inventor: KRAUS KURT
IPC: H02K17/16
Filed: 1976-03-16
Abstract: The motor generates a speed from zero up to the synchronous value. The armature has two or more parallel groups of highly conducting rods (10, 11) with different resistance positive temperature coefficients. The coefficients are so related to each other, that in continuous operation at speeds from zero to synchronous speed the total conductivity is about constant. Preferably the rods are made of materials with melting point above 1000 deg.C and specific conductivity ranging from 10 to 20 gm/sq. mm. Thus one group may be of iron with specific conductivity of 105m/sq. mm, and another one of a copper-nickle alloy with specific conductivity of approximately 20 gm/sq. mm.
