Title: Installation for biological waste water purification
IPC: C02F3/32
Filed: 1988-04-08
Granted: 1993-07-14
Abstract: The invention relates to an installation for the biological purification of waste water (effluent), where, essentially, plants having a strong root system are used in the filter tank and, furthermore, additional tanks are used as stilling tanks and settling tanks. An essential aspect of the invention is the readiness for service even in periods of frost; in frost-free periods the waste water is fed to a tank with a vertical flow pattern on the surface, while at times of frost it is fed distributed through a network of pipes under the surface on a layer of gravel.

Granted: 1998-01-14
Abstract: A continuous carburizing furnace system is disclosed having at least two series-connected rotary furnaces. The rotary carburizing furnace, a rotary equalizing furnace, and a rotary diffusion furnace which may be included between the carburizing and equalizing furnaces, allow trays of parts to be discharged from any position at any time by suitable rotation of their hearths, thus allowing parts with different cycle times to be run simultaneously in each rotary furnace. Each donut-shaped rotary furnace includes one or more captive chain type pusher mechanisms mounted in vertical fashion within a central area or hole, and the rotary carburizing furnace is multi-zoned and includes wall-mounted fans for uniform circumferential control of the gaseous atmosphere within its annular chambers. Two different quenching apparatuses and a slow cool assembly adjacent multiple outlets of the equalizing furnace permit the use of different cooling/quenching processes on selected parts, and parts may also be returned from the slow cool assembly to the equalizing furnace for reheating.

Granted: 1993-05-19
Abstract: Un dispositif optiquement bistable (100) possède des première et seconde régions de puits quantiques multiples à semi-conducteur (101 et 102) ayant des niveaux complémentaires de haute et basse absorption pour émettre des premier et second rayons de lumière de sortie (162 et 163) ayant des niveaux complémentaires de basse et haute puissance. Le dispositif optique comprend des premier et second photodétecteurs (103 et 104) ayant des régions de puits quantiques respectives (101 et 102). Les photodétecteurs sont sensibles aux premier et second rayons de lumière (160 et 161) pour commander électriquement l'absorption optique de chacune des deux régions de puits quantiques. L'état de dispositif est déterminé par le niveau de transmission du rayon de lumière (161) passant au travers de la région de puits quantiques multiples (102) et émis en tant que rayon de lumière de sortie (162), tandis que l'état complémentaire du dispositif est déterminé par le niveau de transmission du rayon de lumière de sortie complèmentaire (162). Simultanément, un atténuateur optique variable (701) fait varier proportionnellement le niveau d'intensité des rayons de lumière d'entrée (160 et 161) pour maintenir l'état du dispositif sur une grande plage d'intensités ou puissances d'entrée. Lorsque le dispositif fonctionne dans la région de fonctionnement bistable, l'un ou l'autre des rayons de lumière de commande (180 et 181) ayant un niveau d'intensité faible change le dispositif d'un état à l'autre. Deux valeurs seuil du rapport de l'intensité de la lumière incidente sur les deux photodétecteurs établissent le point de commutation du dispositif d'un état à l'autre.

Granted: 1994-11-30
Abstract: A circuit and method which eliminates the voltage spike generated by inductive kick, and generates a signal which is active while a relay is being released and for a given period thereafter. This signal can be used to power down circuits supplying signals to relay contacts, thereby allowing the relay to release without current or voltage potentials at its contact, eg. dry switching. The generated signal may also be used to disable sensors which might give false indications while the relay contacts are switching. In telephone line circuits, the generated signal can be used to disable the telephone hook switch detector or to power down the battery feed circuit feeding the subscriber line. The relay coil energy generates a signal which is active while the relay is being released. The invention uses a minimum number of components and the circuit is adjustable as to how long the generated signal remains active after the relay is released.

Abstract: A harmonic coding arrangement where the magnitude spectrum of the input speech is modeled at the analyzer (120) by a relatively small set of parameters and, significantly, as a continuous rather than only a line magnitude spectrum. The synthesizer (160), rather than the analyzer, determines the magnitude, frequency, and phase of a large number of sinusoids which are summed to generate synthetic speech of improved quality. Rather than receiving information explicitly defining the sinusoids from the analyzer, the synthesizer receives the small set of parameters and uses those parameters to determine a spectrum, which, in turn, is used by the synthesizer to determine the sinusoids for synthesis.

Abstract: A method for transmitting modulated waves simultaneously using a plurality of frequencies comprises successive steps of transmission of symbols for a duration T +  DELTA T, two transmission frequencies being separated by 1/T, T being the useful transmission interval and DELTA T being the transition interval. Synchronisation signals are transmitted enabling, on reception, the sampling of the signal for useful transmission intervals of duration T so as to render orthogonal channels corresponding to the various frequencies. The invention applies to the broadcasting and receiving of radio and television transmissions, to devices for receiving analog and/or digital information, to telephone communications between exchanges, to telephone communications between radio telephones and communication stations, to radio communications between terrestrial stations and satellites, to communications between satellites, to acoustic communications in air and/or in water, and to the construction of local computer networks. The invention is particularly well suited to high fidelity radio transmissions as well as to high definition television (HDTV) and/or digital television. <IMAGE>

Abstract: A hydraulically damped rubber cartridge spring incorporates two chamber pairs (4, 6; 5, 7) isolated from one another by a wall (8 ). The chambers are located at a distance from one another in the direction of the introduced vibrations. The chambers of each chamber pair are connected by damping orifices (9, 10) of a channel-like configuration. The damping orifices (9, 10) are so dimensioned and coordinated with the bulge elasticity of the corresponding walls (11) of the bilaternally adjoining chambers, that the contained liquid mass enters into a resonant motion if the vibrations introduced by the spring's operation differ from one another in frequency. The dividing wall (8) contacts the external sleeve (1) loosely when vibrations are not introduced, and at the same time is resiliently deformed toward the internal tube (2) by the external sleeve (1).
