Title: Motor powered entirely by permanent magnets - has north poles of rotor magnets directed to distributed south and north pole pairs of stator for continuous attraction
Inventor: SCHMEER WILHELM
IPC: H02K53/00
Filed: 1989-05-18
Abstract: The like N poles of the rotor magnets point outwards and are permanently subjected to the force field of the stator magnets. The inner ends of the stator permanent magnets form an angle of 45 deg. so that pairs are formed in a V shape, the separation line of the V facing the centre of the magnet motor. The N poles of the rotor permanent magnets are repelled by the like N poles of the stator magnets, but also attracted by the large surface S poles of the stator magnets, producing a clockwise rotation of the rotor. With a pole change, the motor can be run in the opposite direction. The torque at the shaft end can be transmitted by gears or pulleys to other machines, and several stators and rotors on a single driving shaft can produce large magnet motors. Proportional miniaturisation can be used for the toy industry. USE/ADVANTAGE - Motor power produced only with assistance of permanent magnets, for driving generators, pumps and fans. Environmentally friendly, little maintenance required.  Solves waste disposal problems.

Title: Stuffing box split packing ring - has locking section on the butt surfaces of the split in the layered ring
Inventor: TUECKMANTEL HANS-J DIPL ING
IPC: F16J15/20
Filed: 1990-06-16
Abstract: The ring, esp. for stuffing box packings, composed of two part rings formed in layers of flat sealing material, has shaped locking sections (5,6) at the butting surfaces (4) where the ring is split. This allows the split ring (2) to be compressed into a packing ring with a keyed fit. The ring locking sections (5,6) are pref. aligned to take up axial and/or radial forces. Mfr. of the ring is as follows. The sealing material has a dividing gap in it, where the ring is to be stamped, according to the dimensions of the split ring to be formed. The separate rings are stamped as two sepearate split ring layers, sepd. by the gap section, and the layers are placed over each other to form the blank split ring, with the gaps over each other. The locking sections at the facing butt edges of the gap in the split ring are pressed into shape. An adhesive is inserted between the layers for bonding. The flat sealing material is a film or plate of expanded graphite, and the material can be reinforced by a metal foil or a thin metal plate. ADVANTAGE - The ring structure prevents an uncontrolled displacement against each other in the stuffing box, and gives an improved sealing action at the butt surfaces of the split in the ring.
