Abstract: A distributor for use in internal combustion engines requiring sequential application of high voltage to pairs of spark plugs in each cylinder by a separate high voltage supply circuit comprises a base portion (12) and a cap portion (14) formed of like insulative material. The base and cap portions of the distributor contain separate sets of switching contacts (121, 221) connected to associated external terminals (111, 211) and separate rotor conductors (142, 242) on a common rotor element (16). Half the externally mounted terminals in each portion extend in a direction diametrically opposite to the other half so as to eliminate external spark plug wire crossover at the distributor and are electrically connected to the contacts by means of wires internally moulded into the insulation of the portions. An installation alignment feature includes a series of apertures (34, 36, 38) in the rotor and the base, whereby a pin (20) inserted therein aligns the rotor conductors to be in accurate registration with a predetermined pair of switching contacts. A unique hexagonal drive shaft (18) provides for an allowable degree of error in mounting the distributor with respect to an axial drive socket on the engine.

Abstract: A subscriber line access circuit for use in a telecommunications system is disclosed. The subscriber line access circuit includes a power supply bridge in the form of a first resistor inserted in the b-wire (ground potential side) of a subscriber line, a second resistor inserted in the a-wire (supply potential side) of the subscriber line, and a capacitor which bridges the two wires at the terminals of the two resistors on the sides thereof opposite to the respective potential sources. This supply bridge is coupled on the capacitor side with a two-to-four wire hybrid transformer for the two-wire/four-wire transition to the system and includes an evaluating circuit which delivers an indicating signal when the subscriber actuates a ground key. A cutoff circuit is arranged in the power supply bridge between the first and/or second resistor in that bridge and the respective one or ones of the transformer windings at the junction points at which the evaluating circuit is connected. The device for generating call signals is connected to one of these junction points via a coupling contact and a series resistance. The associated cutoff contact of the supply bridge and the coupling contact of the call signal generating device are controlled in such a way that they can be closed only alternatively.

Abstract: A process is provided for the biological treatment of aqueous waste in a pure oxygen activated sludge/ozone disinfection system as well as apparatus to accomplish the process. In this process, the off-gas (22) from an ozone disinfection tank (53), after removal of residual ozone, is blended with the pure oxygen stream (23) needed to supply the requirements of activated sludge treatment basin and ozonation zone. This blending of two streams (22, 23) is carried out either in pipe line or in a specially built and baffled vessel (56). The combined stream (24) is then compressed and split into two portions (25, 26). One portion (25) of the gas is diverted to the activated sludge treatment plant. The rest (26) of the gas is dried to a dew point level and then fed to ozone generator (61). The discharge from the ozone generator (61) contains a small percentage of ozone and is routed to the ozone disinfection tank (53). An alternate of the system, compresses the off-gas (22) first and then combines it with pure oxygen stream (23A). A two bed desiccant type dryer (58) should preferably be empolyed for the drying of the gas stream (26) upstream of the ozone generator (61). A required amount of pure oxygen will be used to purge the inactive bed of the dryer. The wastewater (11) first flows into an oxygenation basin (50), whereby through the action of microorganisms in the presence of an oxygen rich gas, the organics in the wastewater are converted (oxidized) into harmless compounds. The wastewater is discharged into a settling basin (52), where the biomass settles to form activated sludge which is returned to the oxygenation basin (50). The clarified liquid from the settling basin (52) overflows into an ozone contact tank (53) where the ozonated gas (28) is introduced to disinfect the water stream.
