Title: Stator cover for e.g. for boat propeller unit - is made of fabric reinforced epoxy¨ resin sheet with dense abrasion resistant polymer backing bonded in position with epoxy¨ adhesive
Inventor: KNIRSCH HERMANN DIPL ING
IPC: H02K5/128
Filed: 1990-09-28
Abstract: A stator cover is applied to a propeller unit which consists of a magnetic rotor motor whose propeller is the rotor, a flooded rotor space, and a pressure-proof sealed stator, the cylindrical cover of which passes through the gap of the motor. The cylindrical cover of the stator is made of a composite material of a layer of fabric-reinforced epoxy resin on the stator side and an abrasion -resistant non-porous protective layer on the rotor side. The cover is bonded into the stator opening with an epoxy resin and is sealed off vacuum-tight at the ends. When the stator space is evacuated the cover withstands external atmospheric pressure and, for vacuum casting the stator, its space has a filling tube which can be sealed off. The cover is preferably coated with polyvinylidene fluoride, rubber or fused ethylene-vinyl acetate powder on the inner face. ADVANTAGE - The stator cover is reliably capable of withstanding pressures, as for underwater applications. It is also inexpensive. The stator can therefore be directly vacuum-potted without having to be placed in a vacuum chamber; this reduces costs esp. when the motors are large in size. (3pp Dwg.No.1/1)

Title: Rotor asymmetry detection and monitoring equipment - detects modulation of fields affecting terminals using voltage test points
Inventor: ELBERLING KARSTEN
IPC: G01R31/06
Filed: 1991-02-14
Abstract: The arrangement uses detectors for amplified superposition of slip modulation dependent on the degree of damage or asymmetry. Suitably used and arranged test points produce error dependent measurement voltages. An asymmetry modulates all fields around and within the induction machine with the slip frequency and/or its harmonics and hence also affect terminal parameters which can be detected and evaluated. USE/ADVANTAGE - Esp. for detecting and monitoring rotor asymmetry caused by ring or rod breaks. Permanent monitoring or periodic checking can be performed.
Patent DE-4106265-A1 (DE)
Title: Modular mfr. of fibre-bonded honeycomb structural elements - in which heat-resistant hexagonal rubber cores are covered with prepreg, which are bonded to surface sheet contiguously or spaced
Inventor: HUBER DIETRICH
IPC: B29C70/34
Filed: 1991-02-28
Abstract: In the modular mfr. of fibre-bonded structural elements using cores or honeycombs, a heat-resistant hexagonal rubber core is covered with a correspondingly shaped blank of prepreg. The covered cores (10,11) are arranged touching or as required on a prepreg shell and after further treatment of the fibre-bonded element, the rubber core is removed. The covering of the core may be by laying the oversize blank on a hexagonal mould cavity and pressing into it the rubber core and blank so that the overlap of the blank is forced against the sides of the core. USE/ADVANTAGE - Fibre-bound parts such as aircraft control surfaces and nosecones. Due to the size of cores and honeycombs with the prevailing metal cores, bonding failures occur, leading to formation of so-called `air bridges' under the cores. Also the heat of reaction warps the metal cores, leading to irregular and faulty bonded structure. This invention is claimed to avoid these deficiencies, give high strength and minimise prodn. complex
