Abstract: A method is disclosed for reducing the corrosiveness of a water supply, and preventing the generation of red water caused by iron rust, by modifying the Langelier index of the water, which comprises:
     (1) determining the amount of carbon dioxide required to increase the concentration of free carbonic acid in the water based on the existing and desired Langelier indices, and the acceptable pH range, of the water supply;   (2) dissolving the said amount of carbon dioxide gas in the water to generate free carbonic acid in the water; and   (3) adding a substantially saturated aqueous solution of slaked lime to the water supply such that the free carbonic acid is neutralised and the desired Langelier index is achieved.   
     An apparatus for carrying out the method is also disclosed.

Abstract: In a tandem fan gas turbine engine two fan compressor stages are provided connected by a flow duct (14) housing a diverter valve (26) which can be used to admit the flow from the first fan to the second fan or to divert it to exhaust through an auxiliary outlet in which case the second fan draws ambient air in through an auxiliary inlet. The connecting duct is annular in cross section because an inner cylindrical wall surrounds the shaft driving the front fan. The diverter valve which therefore has to operate in the annular duct comprises a pair of flat side lobes (40, 42) connected by curved plates which straddle the inner wall. The valve is operated by a rotary actuator (54) in synchronism with closure means which obstruct or open the auxiliary outlet and inlet.

Abstract: Un appareil d'arrêt de machines sert à arrêter une pelleteuse rotative miniature capable d'être mise en rotation dans un espace réduit, du type ayant un organe rotatif supérieur monté de manière rotative sur un organe inférieur mobile autonome, l'organe rotatif supérieur portant la machine. L'appareil d'arrêt de la machine comprend des soupapes qui commandent chacune un cylindre d'un mât, un cylindre d'un bras et un cylindre de décalage. Une vanne magnétique agencée dans des tubulures qui relient chaque soupape à chaque cylindre passe d'une position de mise en communication à une position d'obturation lorsque la machine atteint une zone critique qui précède une zone d'interférence et un clapet de retenue arrête le courant dans la direction du cylindre lorsqu'il est en position d'obturation. Par conséquent, lorsque la machine atteint la zone critique qui précède la zone d'interférence, elle est instantanément arrêtée, ce qui permet d'éviter de manière fiable des interférences avec la machine. Comme la vanne magnétique est directement agencée dans les tubulures de communication avec les cylindres, la vitesse de réponse de la vanne magnétique sert de délai à l'arrêt de la machine. La zone critique peut ainsi être moins étendue que celle des appareils de l'état antérieur de l'art et la plage de fonctionnement peut être considérablement élargie.

Abstract: On sèche les déchets tels que les carapaces de crevette ou de crabe, les issues de poisson, etc. afin de produire une matière de base ou un additif à grain fin apte à s'utiliser dans les denrées alimentaires et le fourrage pour animaux, en soumettant une matière initiale à un écoulement d'air turbulent dans une chambre, ce qui envoie les mottes de matière dans tous les sens. Les mottes se heurtent en continu les unes contre les autres, ce qui découvre constamment de nouvelles surfaces de rupture. La chambre est alimentée en air dont la température dépend d'une part de la température de la matière initiale et d'autre part de la vitesse de désintégration, le débit d'entrée de l'air étant réglé en fonction de la quantité de matière initiale introduite par unité de temps. L'eau non combinée peut immédiatement quitter par évaporation les surfaces de rupture découvertes. En créant une contre-pression, on peut maintenir la matière dans la chambre jusqu'à ce que les particules aient atteint des dimensions voulues. Si les particules quittant la chambre sont trop grandes, on les sépare puis on les renvoie à l'entrée de ladite chambre.

Abstract: This invention relates to a circuit connection device having overvoltage/overcurrent protection function for communication equipments which can eliminate an overvoltage and an overcurrent. In order to protect communication equipment from overvoltage and overcurrent, a surge absorption element (2) is connected in parallel with terminals for connecting the equipment, and a metal wire (3) having a low melting point is connected in series with them in the proximity of the surge absorption element (3). The communication equipment is protected from surges between the lines of the communication equipment and between the lines and the ground by the surge absorption element and from continuous overvoltage and overcurrent by the low-melting metal wire because the surge absorption element is overheated and the metal wire blows out by the heat.

Title: Coin validators.
Inventor: WAITE TIMOTHY PETER SEVERN DRI
IPC: G07D5/02
Filed: 1990-07-27
Abstract: A coin validator has a thickness sensor formed by two coils positioned one on each side of the coin path. The coil outputs are processed separately to derive values which, when combined, produce a thickness-indicating measurement which is independent of coin position. Each output may be processed to give values which are linearly dependent upon coin position with the same constant of proportionality. Alternatively, one output is scaled relative to the other to an extent dependent upon the thickness for which the coin is to be tested, so that the thickness-indicating measurement does not vary significantly over a region which corresponds to a likely maximum variation in the position of coins of that thickness.

Abstract: Il est présenté un servofrein à dépression comportant un corps de raccordement (23) pour le raccord (2) de la conduite à dépression et le clapet de non-retour à dépression (3). Le corps de raccordement (23) se présente sous forme de boîtier pour un dispositif de mesure, lequel détermine la position du disque de diaphragme (16) à l'intérieur du servocylindre (15). Le dispositif de mesure consiste en un palpeur (22) qui fait tourner une roue dentée (9) au moyen d'une crémaillère flexible (6). La roue dentée fait tourner un curseur (12) sur une résistance ohmique (35). Les variations de tension ainsi fournies donnent des informations sur la position du disque de diaphragme (16) à l'intérieur du servocylindre (15). Grâce au choix judicieux des composants, à leur configuration, à leur adaptation mutuelle ainsi que grâce à l'assemblage judicieux desdits composants en un ensemble compact, on obtient entre autre des dimensions n'excédant pas celles d'un servofrein conventionnel. Ceci réduit l'encombrement pour le montage du servofrein. Le servofrein se prête à un usage universel.

Abstract: A dual band feed arrangement for a microwave antenna provides microwave communication in a lower band and in a substantially widened upper band to provide simultaneous microwave communication for three signals. One signal in the lower band propagates between the outer and inner conductors of a coaxial waveguide in the TE₁₁ coaxial mode, and two signals in the upper band propagate in the inner conductor in TE₁₁ circular waveguide mode. A combiner, having a conically shaped section with a plurality of irises through its sidewall, is coupled to the coaxial waveguide to provide a transformation from the TE₁₁ modes to the HE₁₁ waveguide modes for each of the three signals. A dielectric rod extends from within the inner conductor and into the horn antenna for propagating the second signal out of and into the antenna.
