Patent EP-0331592-A1 (EP)
Inventor: MAIGE PHILIPPE
IPC: H02M1/36
Filed: 1989-02-28
Abstract: The invention relates to the field of switchable power supplies controlled with modulated width pulses obtained by comparison between a saw tooth voltage (15) oscillating between first and second levels, and a control voltage (19), in which the control voltage is initially fixed at a value outside the range of oscillation of the saw tooth, and then, in a first phase varies to the first level (idling time) and in a second phase varies from the first to the second level to produce gradually increasing width control pulses. The invention provides means (45, 50) for ensuring the variation of the control voltage during the first phase in accordance with a first slope, then the variation of this control voltage during the second phase in accordance with a second slope which is smaller than the first, and means (60) for ensuring slope switching following detection of the first control pulse.

Title: Enhanced phosphate removal in an activated sludge wastewater treatment process
Inventor: LEVIN GILBERT V
IPC: C02F3/12
Filed: 1990-06-01
Abstract: There is disclosed an activated sludge wastewater treatment process which comprises aerating a mixed liquor comprising phosphate-containing influent wastewater and activated sludge in an aeration or high-purity oxygen zone to reduce the BOD/COD content of the wastewater and to cause the microorganisms present to take up phosphate. A phosphate-enriched sludge in which the phosphorus is present primarily in the sludge solids is separated from the mixed liquor to provide a substantially phosphate-free effluent. At least a portion of said phosphate-enriched sludge is passed to a phosphate pre-stripping zone, either in a separate tank or within the phosphate stripper tank itself, where BOD/COD-containing water, or feedwater, containing at least 50 mg/L of BOD, is added to poise the sludge organisms to begin enhanced rapid release of dissolved phosphate by pre-stripping it from the sludge or poising the sludge for rapid, enhanced release of phosphate. Thence, the sludge is passed to a phosphate stripping zone. In the phosphate stripping zone, the sludge settles to form a supernatant liquor in the stripping zone upper section and settled sludge in the stripping zone lower section. The settled sludge is maintained under anaerobic conditions for a time sufficient to complete the release of the desired amount of phosphate from the sludge solids to the liquid phase of said settled sludge. At least a portion of the anaerobic sludge from the phosphate stripping zone is recycled to the aeration or high-purity oxygen zone as activated sludge. The phosphate-rich supernatant from the phosphate stripping zone may be applied directly to land, or treated with a chemical precipitating agent to precipitate the phosphate therefrom and the precipitated phosphate may then be removed through the use of a reactor/clarifier, primary or secondary clarifier or other tankage, thus preparing the phosphate for final disposal directly or as fresh, digested or otherwise treated sludge.

Patent EP-0435123-A1 (EP)
Inventor: MUELLER REINHARD DIPL-ING
IPC: H02B13/025
Filed: 1990-12-17
Abstract: In switch or outlet boxes, as are also used on distributing busbars of low-voltage switchgear, in the case of a disturbing arc there is a risk of a sudden pressure increase within milliseconds, as a result of which the pressure-relieving flaps bulge up, which adversely affects the opening movement of the flaps to a high extent. It is thus necessary to construct the pressure relieving wall such that it reacts within a few milliseconds in order to relieve the housing space affected by it in a sudden manner from the internal pressure occurring, without the housing itself or the apparatuses located therein being damaged thereby. This is achieved in that the pressure relieving wall (4) consists of two pressure relieving flaps (9, 10), which abut approximately in the centre of the end wall of the metal housing (3) and each of which is attached by means of an attachment strip (11, 12), which is bent through 90 DEG , to the respectively adjacent housing side wall (13, 14), in that there are perforations (17, 18) as weak zones at the bending edges (15, 16) between the pressure relieving flaps (9, 10) and their attachment strips (11, 12), and in that only one (9) of the two pressure relieving flaps (9, 10) is secured by means of a retaining tongue (19) to the housing (3) of the switch or outlet box (1), while the second pressure relieving flap (10) is supported only at the edge on the first pressure relieving flap (9). <IMAGE>

Abstract: A closure, for example for use on a liquid-filled container (10) comprises a collar (42) having a flange (124). A cap (96) is attached to the collar (42) by a strap (98). The cap (96) has barbs (130), and the flange (124) has notches (132). When the cap is fitted to the collar 42, the barbs (130) engage the flange (124) to prevent removal of the cap (96). The resilience of the strap (98) tends to retain the cap (96) in a predetermined orientation about the central axis of the collar (42). In this predetermined orientation, the barbs (130) are out of alignment with the notches (132). To release the cap (96), it must first be turned, against the restoring force exerted by the strap (98), to bring the barbs (130) into line with the notches (132). The cap can then be removed by pulling on a lug (134), causing disengagement of the barbs (130) from the flange (124) at the notches (132). The manipulation of the cap (96) which is necessary before it can be removed serve to resist opening of the container (10) by, for example, young children.

It is used, among other things, as an additive to fish feed. In the process according to the process according to the invention, trimethylamine-sulfur-trioxide complex is added in only slight molar excess to a concentrated solution of potassium-L-ascorbate in water, and the pH value of this reaction mixture is set by successive additions of potassium hydroxide at a value in the range between 9.5 and 10.5, and is kept at this value for the duration of the reaction. The process permits the profitable production of dipotassium-ascorbate-2-sulfate-dihydrate on a large industrial scale. It is also explained how trimethylamine-sulfur-trioxide complex can be recovered from trimethylamine which occurs as a by-product during the production of dipotassium-ascorbate-2-sulfate.
