Title: Small, slow running synchronous motor - has two stator coils and rotor drum with peripheral tooth-like pole serrations
Inventor: MERKLE PAUL
IPC: H02K19/06
Filed: 1978-11-22
Abstract: The a.c. Synchronous Motor has an externally arranged rotor and an internal stator consisting of two coaxial windings which produce two separate magnetic flux paths. In combination they produce four partial magnetic paths which in the peripheral region of the stator divide into four tangential paths generating an inductive closed loop current in subsidiary stator cages. The turning momentum of this motor is created by the combination of the inductively induced current in the stator rings with the magnetic flux produced by the second stator coil in the rotor. The magnetic flux in the rotor then traverse the stator closed loop in a radial direction, and both these magnetic flux lines alter their directions simultaneously. The rotor drum has on its periphery toothlike pole serrations which have the same pitch over the entire circumference. In contrast, the stator pole disk has only eight such pole serrations distributed over four points 90 deg. apart, e.g. four pairs of teeth only.

Title: Automatic splicer for broken ends on winding frame - transfers threads from above and below into pneumatic chamber
Inventor: ZUMFELD HEINZ
IPC: B65H69/06
Filed: 1978-11-27
Abstract: A mechanism including a chamber having a lengthways running groove, which can be covered by a hinged cover, and into which two ends of yarn can be introduced and spliced by means of a lateral jet or compressed air, serves to join a thread from above to a thread from below. The introduction of the broken ends of the thread into the longitudinal groove is effected by a mobile device for drawing the thread which is displaced from a position in which it locates and picks up the thread to one in which it releases it. The threads are introduced into the chamber either, not crossed, and pref. parallel to each other, and are held until the compressed air is delivered, or they may be crossed during the pivoting action of the thread drawing device. The chamber is closed by a cover. The ends of the thread from above and of the thread from below are automatically sheared. Compressed air is blown into the chamber. Used to effect a joint by a splice between an upper and a lower end of yarn, as in a winding frame, whilst eliminating all the influences which depreciate the quality of the joint and depend upon manual skill.

IPC: C25B11/04
Filed: 1979-01-30
Abstract: Porous, catalyst-free electrode of hot pressed Ni powder is used as anode in the electrolysis of water in alkaline soln. It has a 0.0025-0.1 mu m (10-100 layers of mols.) thick protective coating of NiO on its inner and outer surfaces to produce a min. overvoltage and max. operating life at operating temps. up to 80 degrees C. NiO layer is pref. produced in hot pressing or sintering at 300-500 degrees C by the use of Ni powder contg. sufficient oxygen to form the NiO layer. Alternatively, the Ni surface is first oxidised (electro)chemically to nickel hydroxide and then converted to NiO by thermal decompsn. above 150 degrees C. The electrode can be tempered in an O2 atmos. Anode has good catalytic properties for the liberation of O2, even with long operating time and elevated temps., since the formation of voluminous (hydr)oxides is suppressed.
