Abstract: On fait boillir la substance aqueuse, par exemple eau de mer, on envoie sous pression la vapeur d'eau produite dans une turbine de turbo-alternateur pour produire de l'électricité, on condense la vapeur résiduelle en eau douce et on récupère comme sous-produit le résidu de l'évaporation, par exemple du sel marin. On envoie la vapeur d'eau, directement ou à sa sortie de la turbine, sur du fer chauffé à environ 800°C, ce qui fournit de l'hydrogène et, comme sous-produit, de l'oxyde ferrique et la source d'énergie initiale est, outre l'énergie solaire, toute source d'énergie connue même non rentable, telle que du charbon situé à de grandes profondeurs. La substance aqueuse de départ est, outre l'eau de mer, les boues résiduaires, une solution de sel gemme ou un mélange de boues et de solution saline. Dans le cas des boues, le sous-produit est un engrais sec et stérilisé, transformable en briquettes combustibles. Le résidu sel est transformable par électrolyse en hydrogène et en chlorate de sodium, qui est un carburant, le résidu boues-sel fournit un mélange combustible, boues séchées-chlorate de sodium, mélangeable à des ordures ménagères pour favoriser la combustibilité de celle-ci. Le chlorate de sodium est transformable en chlorate de potassium et la vapeur d'eau sous pression peut être condensée dans des réservoirs éloignés et sa chaleur récupérée. Les énergies produites sont utilisables dans le procédé.

Abstract: Method for preparing glass-silicate from silica and appropriate metal compounds according to the method of melting with thermal pretreatment of the mixture; one of the essential components of the mixture is preheated by means of the heat-energy contained in the residual gas and/or by means of heat-energy coming from other sources; this essential component is thus homogeneously mixed with other component then the heated mixture is brougth to the melting stage. Preheating of the principal component can be carried on until a temperature range provides to the preheated mixture a mean temperature which is below the melting temperature of the alcaline and alcaline-hearth metal components. The main preheated component is for instance sand. If the heat-energy contained within the residual gas is to be recovered, the residual gas must be circulated through heat exchangers.

Abstract: In a fire alarm system individual fire alarms are connected in series by reporting lines with a central signal station. In order to be able to connect a greater number of fire alarms with the individual reporting or signaling lines and/or in order to be able to dispatch an increased amount of current through the reporting lines, the reporting or signaling lines from the last fire alarm of a line are returned back to the central signal station in the form of a ring circuit or loop. Upon the absence of signals at a reporting line an interrogation device is reversed, so that there can be ensured that in the event of a line disturbance or breakdown of a fire alarm the remainder of the fire alarms still can be utilized for giving a signal. The individual fire alarms are structured such that during assembly the inputs and outputs can be mutually interchanged.

Title: Abtragwalze für Faserballen

Abstract: Die vorliegende Erfindung betrifft eine Abtragwalze (11) zum Öffnen von Faserballen durch Loslösen von Faserflocken aus denselben mittels längs einer rotierbaren Welle (12) an dieser befestigter Zahnscheiben. Gemäß der Erfindung umfasst jede Zahnscheibe zwei Halbscheiben (15, 16), welche im wesentlichen die Form eines halben Kreisringes haben; ist für jede Halbscheibe eine ungefähr halbkreisringförmige Schale (17, 18) vorgesehen; ist jede Scheibe in je eine Schale eingegossen, und umschließen die Schalen von sich zu einer Scheibe zusammensetzenden Halbscheiben die Welle ringförmig, wobei sie lösbar aneinander befestigt und durch einen Preßsitz mit der Welle fest verbunden sind. Die erfindungsgemäße Abtragwalze gestattet, beim Vorliegen eines defekten Zahnes (24) die Halbscheibe mit dem defekten Zahn und die dazugehörige Schale einzeln zu ersetzen, ohne die Welle, ihre Befestigungselemente und die auf der Welle befestigten restlichen Scheiben, usw., abmontieren, zerlegen und nach dem Ersetzen der Scheibe mit dem beschädigten Zahn wieder einbauen zu müssen. Man erzielt somit beim Ersetzen der Zähne eine große Ersparnis an Arbeit und eine Verkürzung der dadurch bedingten Betriebsunterbrüche. Weitere Vorteile der erfindungsgemaßen Abtragwalze bestehen in einer beliebigen Einstellmöglichkeit der Staffelung der Zähne der Scheiben gegeneinander. Damit laßt sich das Auftreten unerwünschter Vibrationen der Walze vermeiden. Schließlich ermöglicht das Eingießen der Halbscheiben in die Schalen, innerhalb weiter Grenzen für jeden dieser Teile das geeignetste Material zu wählen. Beispielsweise können die Schalen aus einem leichten und die Scheiben aus einem sehr harten Material hergestellt sein.

Abstract: A suspension assembly for a vehicle provides improving driving stability and adequate riding comfort. A bushing (10g) in the suspension assembly comprises an upper member (17) and lower member (18) respectively formed of resilient material. The upper member (17) is adapted to receive bounding shock and produce a relatively large damping force in comparison with that produced by the lower member (18) against a rebound shock. By increasing the damping force against the rebound shock, the driving stability is remarkably improved and by maintaining the damping force against bounding back at the conventional level, riding comfort can be kept at substantially the conventional level.

Abstract: To provide an indexed drive to a device such as a rotary switch having a detent mechanism, a three step-phase stepping motor is wound with only two of the phases (A, B) in its stator slots (S1- S24). Those slots (.) which would carry the third step-phase winding in a conventional machine are left empty. To index the drive from one detent position (I) to the next position (J), first the step-phase (A) and then the step-phase (B) are energised, to take the detent mechanism past its top dead centre position (X). The drive then continues to the next position (J) under the detent force and its own inertia, while the step-phase (B) is kept energised to provide electrical retardation to prevent overshoot.

Title: Watch case
Inventor: GOGNIAT PAUL
IPC: G04B45/00
Filed: 1982-05-17
Abstract: The watchcase essentially comprises a crystal 1, or other transparent part visible from the outside of the case, assembled to the body 2 or a bezel exclusively by way of a layer 3 of low-temperature solder, in the nature of a silver or tin solder. A layer of barrier coating 5, chromium for example, serves to avoid diffusion of solder in the liquid state to the surface of the crystal. The zone of junction may be masked by a metallic coating 4, and the grip of the solder may be improved with a supplementary junction layer 6. It is thus possible to make watchcases of distinguished appearance, comprising junction areas of narrower width than those required when cement is used for the assembly.
