Title: Motor position sensor for windscreen wiper drive - has passage of commutator segment used as reference
Inventor: BAYHA HEINER
IPC: B60S1/48
Filed: 1980-05-16
Abstract: The dc commutator motor circuit used for a windscreen wiper drive provides a reference signal for the self parking arrangement and employs position sensing of the commutator segments. In a typical design one commutator bar (13) position is modified. For example in an insulation ring (21), which may be part of the mechanical construction of the commutator, a conducting peg (24) is fitted. The peg connects with the end of the armature coil where it enters the segment. An auxiliary fixed contact (19), typically an extra brush, which is offset from the track of the normal brushes (14,15), picks up a voltage impulse each time the peg connects with it. This impulse is then used in the motor control circuit to initiate the required function.

Title: Oxygen enrichment system - by permanent magnet action assisted by centrifugal force
Inventor: BAEHR GOTTFRIED
IPC: F23C99/00
Filed: 1980-12-29
Abstract: The Parent Patent described a system of oxygen enrichment of ambient air by utilising the higher mol. wt. of oxygen than nitrogen in a conical intake channel of permanent magnet material. Several of these systems are now grouped in a hollow body which is revolved so that the centrifugal forces assist the paramagnetic properties of the oxygen molecules. This improves the oxygen enrichment efficiency. Specifically a hollow body with one or more air intake channels has the permanent magnet action intensified by several current-carrying oils, as it revolves. The oxygen enriched layers, which are further away from the centre of rotation, are skimmed off and used for gas turbines, surface water aeration or combustion systems. This process is pref. repeated in several stages.
Patent DE-3108326-A1 (DE)
Title: Process for reducing the halogen content of a particulate polyolefin
Inventor: HATFIELD JAMES ROY
IPC: C08F6/02
Filed: 1981-03-05
Abstract: The invention relates to a process for reducing the halogen content of a particulate polyolefin prepared by catalytic polymerisation of an olefin in the presence of a Ziegler-Natta catalyst. In this process, the polyolefin in the dry state is passed through a gas-fluidised bed, during which the polyolefin in the fluidised bed is brought into contact with gas containing from 0.05 to 2.0% of alkylene oxide, from 5 to 30% of water and the remainder of an inert gas. During this process, the alkylene oxide reacts with the halogen present in the polyolefin, forming an alkylene halohydrin. The alkylene halohydrin is removed from the fluidised bed, reducing the halogen content of the polyolefin. The improvement is that the alkylene oxide is regenerated by bringing the inert gas containing the alkylene halohydrin into contact with an alkali solution in alcohol or water, and then recovering the alkylene oxide formed by reaction of the alkyl halohydrin and the alkali solution.

Title: Process for purifying waste gas formed in a treatment unit during treatment of liquids, and liquid-treatment unit with a waste gas purification unit for carrying out the process
Inventor: POHL KURT M DR ING
IPC: C02F9/00
Filed: 1981-12-24
Abstract: In a treatment unit for contaminated liquids, in particular industrial effluents, waste gases with a pollutant gas content arise in the treatment chamber. To prevent emission of pollutant gas in a simple and operationally reliable manner, the waste gas is introduced into a circulating gas stream, into which a treatment device (10) for purifying the circulating gas by removal of pollutant gas and a gas circulation device (11) are inserted. The purified circulating gas is recycled to the treatment chamber. By selecting an appropriately high flow rate of the circulating gas stream, the pollutant gas concentration can be diluted even upstream of the treatment device (10) to a value equal to or less than the permissible emission concentration. Particularly in batchwise operation, the circulating gas volume is balanced by an external air connection (16) arranged downstream of the treatment device (10). In the case of batchwise operation, the flow rate of the circulating gas stream is appropriately equal to or greater than the maximum flow rate of the liquid flowing into the treatment chamber, so that backflow is prevented. <IMAGE>
