Patent DE-2419466-A1 (DE)
IPC: G04B39/02
Filed: 1974-04-23
Abstract: A groove (7) is machined in a radial direction in the circumferential surface of the glass body (2) of a watch-glass. A plastic is injection moulded onto or into the circumferential surface (6) and the groove, so that the groove is completely filled with plastic. The injection moulded-on plastic forms the sealing ring (9) which adheres firmly to the glass body and, after the injection moulding, can be machined to the correct diameter. The number of watch-glasses intended for stocking can thus be greatly reduced because the diameter of the sealing ring, before use, is adapted precisely to the diameter of the watch case by machining. <IMAGE>

Title: Magnetic switch with pressure - and leak-proof float - uses magnetic attraction for float suspension in lighter liq
Inventor: KUEBLER HEINRICH
IPC: G01F23/74
Filed: 1974-09-07
Abstract: The magnetic switch consists of a non-magnetic guide tube with sealed gas contacts incorporated in an insulating manner. These contacts are actuated in a contactless manner by a magnetic field generated by permanent magnets in floats sliding in the tube according to the level changes up and down. A solid float is suspended in a liquid of lower specific gravity which does not permit normally its floating. The lower float part contains a permanent magnet whose magnetic field, opposed to a magnetic field of a permanent magnet fastened to the tube, permits the float buoyancy. The oppositely polarised magnetic fields provide the desired buoyancy of the switch float. Preferably the magnetic field of the float magnet actuates in a snap-action the sealed gas contact through the non-magnetic tube wall.

Title: Waste water valve connected to vacuum device - has actuator always connected to vacuum system and actuated pilot valve for adjusting vacuum
Inventor: VARIS MARTTI DIPL ING
IPC: E03C1/122
Filed: 1974-10-22
Abstract: The pilot valve of the waste water valve system adjusts the actuating mechanism so that the vacuum in the actuating mechanism either increases or reduced for obtaining a pressure difference for opening the valve. The actuating arrangement has two chambers which exert an influence on a flexible diaphragm. When the valve is closed then a vacuum exists in these chambers. The float in the waste water collection chamber opens the pilot valve when the liquid level increases in the collection chamber so that the atmospheric pressure above the liquid level loads one side of the flexible diaphragm and hence opens the valve. This valve can be adjusted to operate at required collected quantities of waste water in the collection chamber.
