Title: Permanent magnet disc brake - has segmental magnets and armature with inner and outer ring of segments attached to steel rings
Inventor: HALLMANN HERMANN
IPC: F16D65/18
Filed: 1976-09-09
Abstract: The brake comprises an inner and outer ring of permanent magnet segments (4, 6) attached to steel rings (3, 7) with corresponding armature segments (5) in the intervening space. There is an air gap between circumferentially adjacent segments. All magnet faces have opposite polarities. The wheel on which the braking effect is to be exerted (14) lies axially on one side of the magnets. The armature segments, which form the brake blocks, are free to move axially and are located in a non-magnetic plate (17). The magnets can be moved circumferentially through 45 deg. with respect to the armature using a lever (1). With the lever in one extreme position the magnetic circuit is closed by the wheel disc (14) which then attracts the armature and braking results from the friction between blocks (5) and the disc.

Title: Selective strainer for dishwasher - has floating inner sleeve to allow fine particles to flow to pump
IPC: A47L15/42
Filed: 1977-08-25
Abstract: The strainer for a dishwashing machine has a wall (25) provided with fine perforations (29) which retain large particles inside the inner sleeve (32). The fine particles remain in the circulating water and are liable to be deposited on the lower surface of the machine when the water is pumped out after use. To avoid this drawback the inner sleeve (32) is provided with a float in the form of a hollow ring (34). The float (34) holds the sleeve (32) in its upper position when the machine is in use and shuts off the holes (31). As the water level falls the sleeve (32) drops to its lower position so that the holes (31) coincide with the holes (37) allowing the water and the fine particles suspended in it to flow to the outlet (26) and on to the discharge pump.
