Abstract: A magnetic recording and reproducing apparatus for recording a desired sound or picture signal to a magnetic tape by a magnetic head. At the time of normal-speed recording and reproduction, the magnetic tape is taken up at a constant speed, but by changing the tape travelling speed of the tape on the rotary drum, DTF control and high-speed noiseless reproduction are enabled. The tension of the tape on the entrance side of the rotary drum is controlled to a desired value. This apparatus comprises a tape tension actuator and a tape drawing actuator on the entrance side and on the exit side, respectively, of the rotary drum. In DTF control, both tape actuators correct a tracking error of the tape in cooperation with each other. In high-speed noiseless reproduction, both tape actuators are differentially driven so as to lower the tape travelling speed on the rotary drum. Both tape actuators are driven in feedback control using the modern control.

Abstract: Un dopant est incorporé à des grains d'halogénure d'argent pendant leur précipitation. Ces grains d'halogénures d'argent sont produits par une technique à double jet d'émission à courant accéléré. Lorsque 65 % à 90 % environ de la masse d'halogénure d'argent à précipiter ont été ajoutés à la dispersion de précipitation, on y ajoute une quantité d'une solution dopante d'un sel du groupe VIB comprise entre 0,2 et 1,0 mg de sel par mole d'argent. On permet ensuite à la formation de la dispersion de s'achever en continuant à appliquer la technique de précipitation à double jet d'émulsion jusqu'à obtenir les grains de la grandeur voulue. Les grains ainsi obtenus ont leur tiers extérieur composé du sel métallique du groupe VI mélangé avec l'halogénure d'argent. Dans le mode préférentiel de réalisation du procédé, le sel métallique du groupe VIB est un sel de sélénium contenant du sélénocyanate de potassium.

Abstract: Un dispositif connu possède entre la pédale de l'accélérateur et le papillon des gaz, en plus des moyens de transmission mécaniques, également des moyens de transmission électromécaniques avec un élément d'accouplement embrayable. Le désavantage du dispositif connu réside en ce que les moyens de transmission mécaniques doivent avoir, en vue de la compensation de la course, un ressort à course maximale. Par opposition à cela, selon le dispositif de l'invention, un élément d'accouplement à action bilatérale (80) peut relier, suivant la position de l'embrayage, la pédale de l'accélérateur (2) au papillon des gaz (52) par l'intermédiaire des moyens de transmission mécaniques ou électromécaniques. Ce dispositif convient en particulier à des véhicules équipés d'une régulation du glissement et/ou de la vitesse de marche.

Title: Tamper indicating closure having retaining hoop with relief windows.
Inventor: HAYES THOMAS H
IPC: B29C57/00
Filed: 1990-08-22
Abstract: A closure for a container has a tamper indicating band with a band retainer in the form of an apertured flap or hoop which is hinged to the lower edge of the band. A series of windows open through the retainer, extending toward but not to its distal edge. As the retainer is turned inside out from its as-molded position to its use position, its distal and/or hinged edges deform to relieve compression and permit the retainer to be inverted by direct downward pushing force. As a result of the deformation, the retainer in its use position may, depending on the number and size of windows, have an advantageous polygonal peripheral shape rather than a circular shape.

Abstract: L'invention décrit deux procédés permettant d'éliminer par attaque par voie humide une couche d'arrêt d'attaque sans laisser de gravure sous-jacente indésirable. Dans le premier procédé, on utilise une technique d'attaque par ions réactifs, dont l'action est stoppée lorsqu'on arrive sur une couche d'arrêt d'attaque. La couche d'arrêt d'attaque ainsi exposée est éliminée par attaque par voie humide, ce qui laisse une gravure sous-jacente indésirable. La gravure sous-jacente est alors remplie d'un matériau de charge par procédé de dépôt en phase vapeur. On attaque ensuite la charge pour laisser une ouverture à paroi plane ne présentant aucune découpe sous-jacente. Cette dernière attaque peut être une attaque par crépitement suivie par une attaque au plasma. Dans le second procédé, on utilise une technique d'attaque par ions réactifs, dont l'action est stoppée lorsqu'on arrive sur une couche d'arrêt d'attaque, comme dans le premier procédé. Des parois latérales sacrificielles sont ensuite formées dans l'ouverture, puis la couche d'arrêt d'attaque exposée est éliminée par attaque par voie humide, la disposition des parois latérales servant à empêcher la formation de découpes sous-jacentes dans la couche d'arrêt d'attaque. Pour terminer, les parois latérales sacrificielles sont attaquées.

Filed: 1991-07-18
Abstract: Bioadsorbers are proposed for removing heavy metals from aqueous media. These contain polymer-fixed microorganisms in gel spheres, which microorganisms have the ability to selectively adsorb heavy metals present in water at low concentration (for example less than 10 mg/l). The gel spheres are prepared from a polyvinyl alcohol solution containing suitable microorganisms by dropwise addition of the solution into an intensely cold liquid such as nitrogen. By means of very slow thawing, gel spheres are obtained which have high elasticity and abrasion resistance and can thus circulate in a reactor for a relatively long period of time. Regeneration of the bioadsorbers is possible, and the heavy metals can be precipitated from the regeneration solution.

Abstract: The invention relates to a circuitry arrangement by means of which it is possible to suppress frequency components which cause spurious response in the intermediate-frequency amplifier in a radio telephone receiver, which amplifier produces not only the input signal frequency but also harmonic frequencies of this frequency, in which case some harmonic frequency of the frequency component which causes spurious response is the same as the intermediate frequency. In the circuitry, between the signal path and the circuit ground, there is coupled a resonant circuit (B) which is in series resonance at the frequency of the frequency component which causes spurious response, in which case a signal of this frequency is strongly attenuated, and in parallel resonance when the frequency is the intermediate frequency, in which case the attenuation of a signal of this frequency is slight. The invention disclosed makes it possible to select an intermediate frequency which is lower than the reception band multiplied by two, so that even strict requirements set on spurious response can be fulfilled.
