Abstract: In an aerobic process for waste water (effluent) purification with intermittent batch feed of the waste water to the activated sludge tank from which the treated waste water is discharged continuously, the nitrate content of the waste water is simultaneously reduced by the aeration of the activated sludge tank, commencing with the flow of the waste water to the tank, being restricted to values corresponding to </= 0.5 mg/1 of dissolved oxygen, or in particular turned off, until the nitrate content in the tank has fallen below 5 mg/1 or, in particular, below l mg/1. In such treatment of communal waste waters, an approximately 1 hour cycle time is advantageous and the aeration, commencing with the rapid input of the waste water charge, is turned off for about 5 minutes. Suitable feed batches are </= 30% and, in particular, between about 5 and 20% of the tank contents. In this process, the nitrate content is reduced during the phase with oxygen restriction, while in the subsequent phase (over longer periods of time), the ammonium carried in with the waste water feed is converted into nitrate, it being advantageous to provide for an adequate nitric bacteria population in the tank.

Abstract: A pattern plate for making moulds intended for use in the production by sand casting of window seals or similar articles having an undercut bead, includes a plate, a fixed exterior part, an axially movable interior part and a elastomeric ring connecting the interior and exterior part. The interior part moves axially over a short path defined within the exterior part by mechanical stops between an extended position, to which it is pushed back by springs, and a retracted position which it assumes through the action of the compaction pressure. During compaction, an annular elastomer ring located between the interior and exterior parts compresses to compact the mold material in a lateral direction. Upon release, the elastomeric ring returns to its original position facilitating the removal of the mould.

Abstract: A cylindrical reservoir (1) is provided with a lower, funnel-shaped screw cap (2) with a threaded nipple (4) which can be screwed on to a lubricating system. A mobile piston (23) provided with a sealing washer (28) divides the reservoir (1) into a lubricant chamber (3) and a compressed gas chamber (29). Lubricant (32) packaged in a flexible pouch (31) can be introduced into the lubricant chamber (30) after the screw cap (2) is removed. The reservoir (1) contains a pot-shaped space (17) located above the compressed gas chamber (29), which can be hermetically sealed by a screw (12). A double battery (34) for generating a compressed gas which acts on the piston (23) is arranged in the space (17), which communicates with the compressed gas chamber (29) via a gas throughflow orifice (18). The generation of gas induced by the passage of current through the battery (34) can be selected by means of an adjustable element of a resistor (48) lodged in the space (17) in the reservoir (1). This appliance makes it possible to complement or replace, easily, rapidly and whenever desired, the consumption materials, namely the lubricant and the battery, and to reuse the other parts of the applicance.

Abstract: Est décrit un canon électronique à large surface dans lequel un faisceau électronique émane d'électrons d'émission secondaire émis par une cible bombardée par des ions. Un bâti principal cylindrique (12) comporte une région centrale où est située la cible d'émission secondaire, et des bâtis auxiliaires (52 et 54) sur des côtés opposés de la cible, à l'extérieur du bâti principal (12), contiennent des plasmas ioniques à faible température. Des faisceaux ioniques sont extraits des régions périphériques des plasmas et pénètrent dans des fentes ou des orifices étroits (38 et 40) reliant les bâtis auxiliaires (52 et 54) avec le bâti principal (12). Une pression supérieure dans les bâtis auxiliaires (52 et 54), par rapport au bâti principal (12), supporte le flux ionique qui aboutit dans le bâti principal. Les faisceaux ioniques présentent un faible angle d'incidence par rapport au plan de la cible et peuvent être légèrement au-dessus ou au-dessus de la cible. Dans le cas où le faisceau pénètre depuis un point situé au-dessus de la cible, cette dernière est segmentée comme des stores vénitiens. Les électrons secondaires quittent le bâti principal (12) par une fenêtre en feuille (44) de sorte que le faisceau électronique est presque perpendiculaire aux faisceaux ioniques.
