Title: Filter for synthetic plastic melts
Inventor: GNEUSS DETLEF
IPC: B29C48/03
Filed: 1993-05-07
Abstract: The invention relates to a melt filter for the cleaning of plastic melts with a screen disc (8) which is rotationally drivable between two plates (1, 2) and has recesses (9) along a circular path (10), into which recesses screen inserts (21) each in the form of a ring (11) equipped with a perforated disc supporting filter layers (13) can be inserted and from which they can be removed, and with a melt channel (17) penetrating the plates (1, 2) in the region of the circular path (10), and also with a ratchet-wheel drive driving the screen disc (8). The aim of the invention is to provide a melt filter which has favourable operating characteristics and in particular permits the uniform pressurisation of all intermediate regions of the filters. For this purpose, it is proposed that the melt channel (17) has a circular inlet opening, starting from which it is enlarged vertically within the plate and then divides and is directed towards the two screen inserts disposed in the working position, and that downstream of the two screen inserts located in the working position, two partial melt channels converge on the circular outlet opening of the second plate. <IMAGE>

Abstract: The invention relates to a method for recovering the carrier in the demodulation of digitally modulated signals and arrangements for carrying out the method. The carrier is recovered with the aid of the digital CORDIC loop in the phase domain, preferably with selective level input. For this purpose, the filtered complex baseband signal is converted from the cartesian coordinate representation into the amount/phase representation (polar coordinates) with the aid of the CORDIC algorithm. The dependence of the difference phase on the modulation signal is eliminated by a multiplication by the factor M and a subsequent modulo-2 pi  characteristic in the case of MPSK-modulated signals. An adaptive loop behaviour can be achieved by selectively introducing the amount of the base band signal into the phase detector signal. As an alternative to this, a complex quadrature mixing of the filtered complex base band signal can first be carried out and then the complex quadrature-mixer output signal can be converted from the cartesian representation to the polar coordinate representation with the aid of the CORDIC algorithm. To increase the lock-in range of the loop, an AFC control loop can be additionally provided. <IMAGE>

Abstract: In a multiple tool for a punch press, a plurality of punches (57) are arranged circularly so as to be movable up and down within a stripper guide (41) provided also movably up and down in an upper die holding member (15) of the punch press; a punch driver (77) is disposed so as to be rotatable and movable up and down in a central hole (75) within the stripper guide (41); and a projecting portion (97) is formed in the punch driver (77), for striking any one of a plurality of the punches. Further, an indexing device is mounted to rotate the punch driver (77) so that the projecting portion (97) can be indexed over any required punch (57A), for instance. Since only one required punch of a plurality of the punches can be struck without moving the striker, the multiple tool is simple in structure, high in precision, and low in cost.

Abstract: A process and apparatus is disclosed for providing access to the interior of a vacuum deposition chamber in a vacuum deposition apparatus (10) without exposing residues, such as chlorosilane residues, within the chamber to moisture and/or oxygen-containing gases. The process comprises first placing over the upper surface of the vacuum deposition apparatus (10) an enclosure (40) which has a bottom opening large enough to completely cover the top opening to the chamber, and which is capable of being filled with one or more non-reactive gases. One or more non-reactive gases are then flowed into the enclosure (40) to purge moisture and/or oxygen-containing gases from the enclosure. After the enclosure (40) has been mounted on the apparatus (10) and purged by the flow of non-reactive gases therein, the vacuum deposition chamber may be opened, while continuing the flow of non-reactive gases into the enclosure (40). After servicing, the vacuum deposition chamber may be resealed, the flow of non-reactive gases shut off, and the enclosure (40) then removed from the apparatus (10). In a preferred embodiment, the flow of non-reactive gases into the enclosure (40) is positioned to flow down from the top of the enclosure (40) at a right angle to openings (44) in the sidewall (43) of the enclosure (40) provided for accessing the vacuum deposition chamber, to thereby provide a gas curtain of non-reactive gas flow across the openings (44) to inhibit ingress of moisture and/or oxygen-containing gases, as well as particulate impurities, into the enclosure (40).

IPC: H04J14/02
Filed: 1993-12-03
Abstract: A wavelength-multiplexed optical signal identification technique in which each of the individual optical signals within a multiplexed signal are modulated at a unique low-frequency. This modulation is performed at the transmission site of the optical signal, and the specific frequencies of modulation are chosen to be very much lower than the low-frequency cut-off of any other information encoded upon the optical signals. At the reception site of the multiplexed signal, the invention directs each of the individual optical signals, as a function of the particular low-frequency modulation evident upon each signal, to a particular tunable Fabry-Perot optical filter. As Fabry-Perot filters have the ability to track the frequency of an individual channel, problems associated with wavelength drift are eliminated. Furthermore, Fabry-Perot filters offer a very narrow optical passband, allowing inter-channel cross-talk and noise levels to be minimized within wavelength-multiplexed optical systems employing the signal identification technique.

Abstract: L'alcalinité totale d'un fluide aqueux de travail du métal est contrôlée et régulée par un procédé de titrage continu qui alimente en continu un courant de fluide de travail du métal, à un débit réglable connu, vers une chambre traversée par un écoulement et possédant un élément de mélange statique. On injecte simultanément et séparément un courant de l'agent de titrage, acide à concentration d'acide connue, dans la chambre traversée par l'écoulement à un débit réglable connu. L'agent de titrage acide et le fluide de travail du métal se mélangent et sont mis en réaction dans la chambre, et le fluide de travail du métal qui a donné lieu à une réaction, en sortant de la chambre, passe sur l'embout d'une électrode à pH. Le pH du fluide de travail du métal mis en réaction est contrôlé de façon continue et la sortie de l'électrode à pH est utilisée pour réguler l'écoulement de l'agent de titrage acide vers la chambre jusqu'à ce qu'une soupape à pH à point final (généralement un pH de 4) soit atteinte. L'alcalinité totale est ensuite déterminée a) à partir des débits connus du fluide aqueux de travail du métal et de l'agent de titrage acide et de la concentration d'acide connue de l'agent de titrage, ou à partir de courbes d'étalonnage déterminées par le report graphique des coordonnées XY du volume de titrage par rapport à la concentration connue de fluide de travail du métal.

Filed: 1993-06-04
Abstract: Dans le traitement de signaux numériques il est très souvent nécessaire d'obtenir le plus rapidement possible la somme d'une chaîne de produits. Les processeurs de signaux connus utilisent souvent deux bus de données séparés, par l'intermédiaire desquels on introduit en parallèle chacune des valeurs à multiplier en partant du principe que lesdites valeurs proviennent de sources différentes, telles que des mémoires différentes et, étant donné qu'un produit de deux nombres binaires possède un nombre double de positions, on utilise un additionneur avec une largeur de mots double. Afin de simplifier ce processus en réduisant le moins possible la vitesse du traitement, l'invention propose d'utiliser un additionneur avec une largeur de mots simple et de traiter les bits les plus forts et les plus faibles du produit en deux phases successives, ce qui permet d'introduire simultanément et successivement les valeurs à multiplier.
