Patent EP-0426273-A1 (EP)
Inventor: FAULKNER ERIC A DR
IPC: F04B43/08
Filed: 1990-05-23
Abstract: The invention provides a pump suitable for medical applications such as the intravenous supply of fluids to a patient. Operative with a length of standard p.v.c. tubing (1) means (2) are provided for deforming the tubing locally to reduce its volume by squeezing first in one direction and then in another tending to restore its original cross-sectional shape, whilst inlet (12) and outlet (13) valve means are operated on either side of the deforming means. The deforming means consists of two members arranged with interdigitated ridges shaped to accommodate the tubing and deform this as one member is moved like a shuttle relative to the other. Each valve means consists of a rotatable member having a profiled surface which bears on the tubing to produce occlusion when the valve is required to shut off fluid flow.

Abstract: An industrial door comprising a pair of side panels (5) and a pair of central panels (6) with each central panel having approximately twice the horizontal width of a side panel. The upper end of one side edge of each side panel is pivoted to the jamb of a doorway (2), while the upper end of the opposite side edge of each side panel is pivoted to the adjacent side edge of a center panel. A track (30) is located above the doorway (2) and a pair of trolleys (24) are mounted for movement on the track (30). Each trolley (24) includes a vertical pivot shaft (23) which is connected to a center panel (6) at a location midway of the width ofthe panel. A drive mechanism is mounted in the header (4) and includes an endless cable (31) which is connected through a torque arm (33) to the shaft of each trolley. Operation of a reversible drive mechan­ism in one direction will operate through the cable (31) to move the panels to a closed position where they enclose the doorway (2), while operation of the drive mechanism in the opposite direction will move the panels to the open or folded position. Flexible weather strips (70) can be connected between the side edge of each side panel and the door jamb, and similarly flexible weather strips (83) can interconnect the adjacent side edges of the side panels and center panels. To ensure that the panels fold in the proper manner, resilient shock cords (85) inter­connect the adjacent side edges of the side and center panels.

Abstract: In the process for chlorine-free bleaching of pulps by means of ozone, a pulp suspension is contacted at a temperature of 15 - 80 DEG C, preferably 40 - 70 DEG C, and at a pH of 1-8, preferably 2-3, with an ozone-containing gas, while vigorously stirring or mixing. The ozone-containing gas contains 20-300 g/m<3>, preferably 50-150 g/m<3>, of ozone. At most 2% by mass, preferably 0.05 - 0.5% by mass, of ozone is used relative to absolutely dry pulp. In order to make this process suitable for a pulp suspension in the medium consistency (MC) range, i.e. for a pulp suspension having a stock consistency of 3 - 20% by mass, preferably 5 - 20% by mass and especially 7 - 15% by mass, the ozone-containing gas is introduced according to the invention under a pressure of 1 - 15 bar, preferably 1.1 - 10 bar, into the pulp suspension. The process can also be carried out in a multi-stage bleaching process once or several times. <IMAGE>

Abstract: L'invention concerne un système de transmission à spectre étendu dans lequel un ou plusieurs signaux à spectre étendu occupent la même bande de fréquences qu'un groupe de canaux de communication classiques espacés régulièrement, l'espacement en lignes spectrales des signaux à spectre étendu étant sélectionné pour correspondre à l'espacement intercanaux du groupe de canaux de communications, de sorte que les composantes spectrales des signaux à spectre étendus tombent dans les bandes de garde intercanaux des canaux de communications. Si l'on utilise plus d'un canal à spectre étendu, ils sont multiplexés par division des fréquences par décalage des fréquences centrales ou porteuses des signaux à spectres étendus par une fraction de l'espacement en lignes spectrales des signaux. Les signaux sont produits par modulation d'une porteuse à l'aide d'un signal de code de pseudo-bruit (PB). On procède au démultiplexage par production du même code PB dans un générateur de codes (47), et par mélange du code PB avec le signal reçu dans un mélangeur (45). L'époque du code produit par le générateur (47) est ensuite avancée ou retardée en réponse à un signal de commande d'époque (48) émis par un contrôleur (46). On passe le signal mélangé dans un filtre à bande étroite (49) afin de sélectionner le signal de la bande de base lequel est ensuite transmis au contrôleur (46) afin de permettre l'émission du signal de commande d'époque (48). Lorsqu'on l'applique à un système de poursuite de véhicules, on utilise la relation entre l'époque du code de bruit et du signal de référence (50) afin d'indiquer la temporisation de la propagation relative, une fois obtenue la corrélation avec le signal reçu. On peut utiliser les informations de temporisation, lorsqu'on les combine avec des informations provenant de récepteurs se trouvant à d'autres emplacements, afin de calculer la position de l'émetteur.

Abstract: Apparatus, for a paper box folding machine for folding the trailing panels of carton blanks about fold lines as the blanks travel individually and successively along a paper line (20) has a servomotor (50) running continuously at a relatively constant nominal angular velocity which drives an input shaft (57) to an indexer (51) that controls, for each position of its input shaft (57), the angular position of an output shaft (24). The indexer (51) converts continuous input from the servomotor (50) to discontinuous motion of its output shaft (24). The output shaft (24) lies below and transverse to the paper line (20). Radially extending fingers (25) mounted on the output shaft (24) are positioned below a trailing panel as the carton blank passes. The indexer output shaft (24) and fingers (25) rotate rapidly so the fingers engage and fold the trailing panel and then dwell to allow the blank to exit the apparatus. Then the shaft (24) and fingers (25) move below the paper lines (20) to allow another blank to enter and rotate to engage a next blank in sequence. A specific embodiment includes two folding stations and a control system for operating these stations independently.
