Abstract: In a corn harvester having a transverse cutter table (10) including rotating, toothed carrier discs (21) and rotating cutters therebelow as well as guide sections (30) defining inlet channels (33) for the cut stems in combination with the discs, a transport worm (40) disposed in parallel with the cutter table is so positioned that in operation it sweeps the upper side of the carrier teeth in the region of the outlet ends of the inlet channels. Each guide section carries a helical, rearwardly rising chute which defines the inlet channel downwardly and contributes to providing a regular and proper flow of stems with the root end forwardly through the channel.

Abstract: Transdermal estrogen progestin absorption dosage units have been developed which comprise a backing layer, an adjoining polymer layer is an adhesive layer in which at least minimum effective dose of an estrogen is dissolved or microdispersed. Adhered to the polymer layer is an adhesive layer in which is dissolved and or microdispersed at least minimum doses of progestin. Presently preferred is use of the natural estrogen, 17-beta-estradiol, or ethinyl estradiol or combinations thereof and of the progestin, norethindrone or norgestimate or combinations thereof. The units have biologically acceptable adhesive and polymer layers. The adhesive layer can have dispersed one or more skin permeation enhancing agents. A separating layer can optionally be used in making the dosage units, which separate space the adhesive and polymer layers, which permits estrogen transmission from the polymer layer during treatment. Dosage units are provided which transdermally deliver at least minimum daily doses of the estrogen and progestin for multiple days, such as for one week. The invention also provides a process of fertility control and estrogen replacement therapy using the novel dosage units. Also. the invention provides a fertility control system for fertility control using the novel dosage units.

Abstract: Un répondeur (14) reçoit un signal de porteuse (16) de fréquence F d'une unité interrogatrice (12). La porteuse reçue (16) est redressée par un circuit à diode (22) afin de fournir l'énergie nécessaire au fonctionnement du dispositif. Des circuits logiques/synchroniseurs (24) dérivent de la porteuse reçue (16) un signal de synchronisation (28) et un deuxième courant porteur de fréquence F/n. Le signal de synchronisation lit un mot de données dans une mémoire morte programmable (PROM). Ce mot est codé et mélangé dans le circuit à diode (22), qui sert de modulateur équilibré, avec la deuxième fréquence porteuse, puis transmis à l'interrogateur (12), où le signal est décodé afin d'identifier le répondeur (14). Tous les circuits électriques du répondeur (14) sont agencés sur une seule puce à semi-conducteurs monolithique (98). Une bobine-antenne (20) peut être placée autour de la périphérie de la puce (98). Des éléments divers peuvent être connectés aux éléments monolithiques afin d'assurer des fonctions supplémentaires: syntonisation du récepteur, commande de fréquence à cristal et alimentation par piles.

Abstract: Système hydraulique de freinage à commande électronique (34) pour véhicules à grande puissance comprenant un mécanisme commandé par l'opérateur qui donne des signaux indépendants de commande de pression de freinage dont chacun est transmis à des commandes auxiliaires distinctes (36, 38). Chaque commande transmet son signal de commande aux autres commandes auxiliaires ainsi qu'à une unité principale de commande (42). L'unité principale de commande choisit parmi les signaux de commande et donne un signal préliminaire de demande de pression de freinage qui est transmis en retour à chacune des commandes auxiliaires. Chaque commande auxiliaire examine ensuite le signal de demande de pression de freinage provenant de l'unité de commande principale et actionne les freins correspondants du véhicule si le signal de demande de pression de freinage se trouve dans les limites normales. Si le signal ne se trouve pas dans ces limites normales chacunes des commandes auxiliaires est capable de donner un signal de demande de pression de freinage indépendamment de l'unité de commande principale.

Inventor: KULLING ACHIM DR
IPC: C01B17/90
Filed: 1988-02-03
Abstract: The invention relates to a process for energy- and material-saving treatment of the diluted acid which is obtained in the manufacture of titanium dioxide and contains 20 to 24 % by weight of H2SO4 and dissolved metal sulphates. This acid is directly contacted in circulation with hot, unpurified calcination off-gases and preconcentrated to a concentration of 26 to 29 % by weight of H2SO4 and the concentration of this acid is kept constant by adding further diluted acid and unpurified calcination off-gases into the circulation. A residue then precipitates which essentially contains titanium dioxide as well as calcium sulphate and a little silica. After previous addition of anhydrite seeds, as necessary, to the preconcentrated acid, the residue is separated off, preferably in a membrane filter press, freed of the major part of the calcium sulphate by washing with water and recycled into the titanium dioxide manufacturing process. In the case of relatively iron-rich diluted acids, for example those originating from ilmenite, a mixture of water-containing metal sulphates, which is called "green salt" and contains predominantly iron(II) sulphate heptahydrate, is precipitated by cooling crystallisation from the preconcentrated acid separated from the residue, and separated off. This step is unnecessary in the case of acids containing less iron. The acid is then concentrated up to 60 to 71 % by weight of H2SO4, metal sulphates ("filter salt") precipitating which are likewise separated off. The acid is recycled to the raw material digestion, and the filter salt can be thermally cracked, the cracking gases being processed to give high-percentage sulphuric acid. Alternatively, the filter salt can be neutralised. During the preconcentration and further concentration, at least 80 % by weight of the calcium sulphate originally present in the diluted acid can be precipitated and separated off.

Abstract: The device comprises a first controlled attenuator (13) placed ahead of the amplifier (7) of the loudspeaker (8) and supervised by an oscillation detector (9) at the output of the microphone (1). It is supplemented with a second controlled attenuator (80) inserted at the output of the microphone (1) and controlled by a variable-threshold level detector (83) receiving on an input (831) a threshold-adjusting value delivered by a level-threshold generator (84) operating from the signal for exciting the loudspeaker (8), and on another input (83), the output signal from the microphone (1). This second controlled attenuator (80), brought into service when the signal from the microphone (1) passes below a variable threshold proportional to the level of the signal for exciting the loudspeaker (8), enhances the effectiveness of the anti-Larsen device and improves the subjective listening comfort of the telephone set. Its effect is improved by the presence of a third controlled attenuator (83) inserted ahead of the amplifier (7) of the loudspeaker (8) and controlled in opposition with it. <IMAGE>

Abstract: Pour tenir compte de la constante de temps de décroissance de l'intensité de la scintillation lumineuse et de la fluctuation statistique de la scintillation, qui est un facteur de déterioration de la résolution, il convient d'intégrer l'impulsion électrique résultant de la détection d'un évènement par des tubes photomultiplicateurs. Si, pendant cette intégration, un phénomène d'empilement se produit, une deuxième impulsion se superpose à la première et fausse le calcul des coordonnées de la scintillation. On élimine cet empilement en validant le calcul de ces coordonnées par une vérification de la valeur atteinte par l'énergie de la scintillation à l'issue de cette intégration. La valeur de cette énergie est mesurée par intégration du signal représentatif de l'intensite de la scintillation lumineuse.
