Patent EP-0059330-B1 (EP)
IPC: A23G9/08
Filed: 1982-02-04
Granted: 1986-12-30
Abstract: The circuit of a gas-compression refrigerating unit in ice-cream making machines and/or ice-cream mixture pasteurizing machines has inserted therein a by-pass circuit controlled by one or more switching valves. During the cycle of pasteurization and/or sterilization of the ice-cream mixture and of the elements of the machine contacting said mixture (either liquid or frozen), the hot refrigerant gas coming from the compressor is diverted through the evaporator (by-passing both the condenser and expansion valve) so as to heat to a sterilization temperature all the elements of the apparatus which usually are cooled by said evaporator. On completion of this pasteurization and/or sterilization cycle, said by-pass circuit in shut off and the refrigeration cycle is resumed by switching said valves, whereby the fluid refrigerant is circulated from the compressor to the condenser and expansion valves into the evaporator so as to refrigerate the elements that are in heat exchange relationship with said evaporator.

IPC: C02F3/12

Granted: 1989-04-26
Abstract: The problem of rising sludge in biological wastewater treatment secondary clarifiers is overcome by minimizing entrainment of nitrogen gas with mixed liquor entering the transfer pipe to the clarifier such that the level of dissolved nitrogen in the biomass settling in the clarifier remains less than that in equilibrium with nitrogen gas at the pressure prevailing in the biomass. This invention is most efficacious in cases where soluble oxides of nitrogen are present and are reduced by the biomass to elemental nitrogen. In accordance with one described embodiment the excess nitrogen is removed by degassing of the mixed liquor in the effluent pit of the system by deepening and widening the usual pit in such manner that the rate of descent of mixed liquor therein to a discharge outlet is less than 0.4 feet per second and the depth is greater than 4 feet, thus permitting the gas-containing macrobubbles to rise to the surface of the pit where these are degassed. The mixed liquor thus freed of macrobubbles is then passed through a hydraulic pressure zone enroute to the clarifier in which pressure zone the nuclei microbubbles are caused to dissolve.

Abstract: In this device, uncertainties previously occurring in the case of operation occurring manually by key and/or electromechanically or also automatically by means of in-built resetting magnets are to be eliminated. This is done in that a drive preparation rack, supported on the same shaft together with resetting rack and drive bridge, swings, under the action of a spring, against the switching drives still engaged after the resetting operation has begun, which drive preparation rack swings along with the steady preparation of the switching drives until, when the zeroing or resetting device is carried back after completed resetting, shortly before the basic position is reached and when the switching drives are engaged again, it lifts away in order to release the latter. <IMAGE>

Une unité (102) de commande du profil exécute la commande en fonction des composantes de déplacement (epsilonX, epsilonY, epsilonZ) des axes générés par la tête traceuse afin de produire une instruction de vitesse VZ de l'axe Z et de déplacer la tête traceuse dans le sens de l'axe Z. L'unité de commande numérique (101) compte le nombre d'impulsions (FZ) générées après chaque rotation sur un angle prédéterminé d'un moteur (MZ) d'entraînement de l'axe de commande du profil. L'unité de commande numérique obtient en outre une position d'instruction des axes de commande numérique (axes X, Y) en utilisant les données de passage, et soustrait de la position d'instruction des délais asservis de temporisation (Ex, Ey) qui constituent le contenu de registres d'erreurs (ERx, ERy), afin d'obtenir une position présente en termes de position mécanique.
