Abstract: Appareil et procédé de renvoi automatique d'appel, ou par réponse sélective, pour transmettre un message à un ou plusieurs dispositifs de recherche (12) qui ont une capacité d'accusé de réception. Dans un mode de réalisation, l'appareil de la présente invention transmet automatiquement un message à un autre dispositif de recherche de personne du système lorsque le dispositif de recherche de pesonne ayant été appelé initialement n'accuse pas réception du message dans une période de temps prédéterminée. Cet autre dispositif de recherche de personne est déterminé à partir d'une liste hiérarchique établie de recherche (42) qui est incluse dans l'appareil terminal de recherche de personne lui-même. Dans un autre mode de réalisation, lorsque les dispositifs de recherche de personne du système ont une capacité de réponse d'accusé de réception multiple, un dispositif de recherche appelé (12) peut demander que le message reçu soit renvoyé automatiquement à un ou plusieurs autres dispositifs de recherche de personne du système selon la réponse d'accusé de réception particulière choisie par l'utilisateur du dispositif de recherche de personne appelé.

Title: Dispositif de dosage de substances liquides ou coulantes
Inventor: OPP ERNST
IPC: F04C9/00
Filed: 1989-04-26
Abstract: Un dispositif de dosage de substances liquides ou coulantes comprend un cylindre creux avec deux raccords pour tubes ou tuyaux. Dans les dispositifs connus de ce type, qui travaillent par exemple avec des pompes à piston, l'air peut pénétrer dans l'espace situé derrière le piston, ce qui peut entraîner le dépôt d'incrustations sur celui-ci dans de nombreux cas d'application, par contact avec la substance à doser, avec des effets secondaires éventuels indésirables. On évite ces inconvénients avec un nouveau dispositif ayant un cylindre creux (1) dont un des côtés frontaux est fermé et qui présente une nervure (11) en forme de secteur qui s'étend de la paroi jusqu'au milieu du cylindre. Dans le sens de la hauteur, cette nervure s'étend du fond du cylindre jusqu'à environ son autre extrémité. Un élément cylindrique (12) est solidarisé à la nervure. A l'autre extrémité du cylindre est agencé un couvercle rotatif (22) qui ferme hermétiquement le cylindre et qui est pourvu lui aussi d'une nervure (21) en forme de secteur qui s'étend jusqu'au fond (14) du cylindre creux (1). Il s'agit fondamentalement d'une pompe de dosage fermée à auto-aspiration et à double action, dans l'espace intérieur de laquelle l'air ne peut pas pénétrer.

The invention concerns also such an extrusion device. In the extrusion device according to the invention it is used an optional number of stator and rotor means (2, 3, 4) arranged packlike alternately one within the other, whereby the extrudable material is first melted during its feed into an annular feed defile (5) advantageously in conical or double-conical form between the stator means (2, 3) and the rotor means (4) after the infeed thereof before the central channel, and thereafter compressed to the final extrusion pressure. The feed defile (5) of the extrusion device according to the invention comprises in the flow direction of the extrudable material first an infeed zone (51), then a melting zone (52) and finally a compression zone (53). The invention relates further to a new extrusion product, which is a multilayer product, and at least one layer whereof includes an interlacing orientation field, in which the plastic is helically oriented or directed forming a reinforcing netlike structure into the product.

Abstract: A medical and dental curable material is disclosed, which contains at least one of a-tricalcium phosphate and tetracalcium phosphate as a necessary ingredient. Conventional medical and dental curing materials containing a-tricalcium phosphate and/or tetracalcium phosphate as a necessary ingredient are unsatisfactory as to kneading workability and curing time since an aqueous solution of a single kind of organic acid is used as a curing agent. The medical and dental material of the present invention, which is satisfactory as to both kneading workability and curing time, uses as a curing- adjusting agent (1) tannin, (2) tannin and collagen, (3) collagen and organic acid, (4) tannin, collagen and organic acid, (5) tannin and organic acid or (6) at least two organic acids.

Abstract: A process for removing trace amounts of water soluble organic and inorganic substances dissolved in a water supply from the water supply includes the steps of flowing water from the water supply including trace amounts of the water soluble substances dissolved therein adjacent to and in contact with one side of a semipermeable barrier within a chamber, inducing evaporation of the trace amounts of the water soluble substances from the flowing water and permeating the evaporated water into the barrier. The water soluble organic and inorganic substances are removed from the barrier and chamber thereby further inducing evaporation and removal of the water soluble substances from the flowing water. The flowing water free of trace amounts of the water soluble organic and inorganic substances are also removed from the chamber.

Patent EP-0428444-A1 (EP)
Inventor: CORNEC JEAN-PAUL
IPC: H04B1/707
Filed: 1990-11-09
Abstract: A signal (RF) whose carrier (FP) is phase-modulated by a digital pseudo-random sequence (SQ), itself phase-modulated by a data signal, is received in a demodulator. A frequency (FL) close to the carrier is modulated locally by a sequence (SL) identical with the sequence received (SQ). The received and local signals are mixed into a filtered signal (SF) in an intermediate frequency band (DFIL). Recourse is had to a repetitive step of double integration of the filtered signal into an integrated signal (SI) which is compared with a threshold (SE) in order to quantify the correlation between the received and local signals. First of all, the local frequency varies in accordance with a few discrete values distributed in the range of uncertainty ( SIMILAR 100 kHz) of the carrier (FP) corresponding to intermediate frequencies (FI) in the vicinity of the filtering band (DFIL). At each discrete value of frequency, integration steps are carried out in respect of shifts of a local sequence half-bit. Synchronisation of the sequences is acquired in response to an integrated signal exceeding the said threshold at the end of an integration step. Then, the value of the carrier frequency is estimated by averaging numerous discrete local frequencies corresponding to favourable integration steps (SE > SI) and included within a band centred on the frequency found during synchronisation of the sequences. The invention also relates to the slaving of the amplification gain in correlators (2) of the demodulator.
