Abstract: An end fitting or coupling shown in Figure 1 comprises an insert member (10) and a ferrule (11) arranged to be attached to a hose (12). The insert member (10) comprises an external coupling portion (13) and an insert portion (14) joined by a flange portion (15). The ferrule (11) has teeth (16) adapted to grip the hose (12) and the insert portion (14) has teeth (17) for the same purpose. The ferrule (11) is provided with a latch portion (18) and an adjacent shoulder (20), the shoulder (20) being of greater diameter than the latch portion (18). The insert portion (14) is provided with a groove (19) adapted to receive the latch portion (18) and a surface (21) in the form of a rib adapted to be contracted by the shoulder (20). When the ferrule (11) is crimped onto the hose (12) the latch (18) enters the groove (19) so that the latch (18) is actually in full contact with the base surface of the groove (19). At the same time the shoulder (20) comes into full contact with the surface (21). The action of these two contact areas is to ensure that the ferrule (11) remains concentrically aligned with the insert member (10) when crimped onto the hose (12).

Abstract: Un dispositif de comptage, par exemple un parcomètre, peut fonctionner à l'aide d'une pile (17) avec un circuit de traitement et de commande (16) qui établit une commutation entre un mode de haute puissance et un mode de faible puissance en coopération avec une carte (C) ayant deux bandes magnétiques séparées (M4, M5) sur une face de sa bande magnétique de données (M1, N1, M2, N2, M3). Un senseur magnétique (HS) en face d'un obturateur (SH) est validé en continu dans le mode de faible puissance. Lorsqu'une carte (C) est introduite manuellement et que la première bande magnétique (M4) passe par le senseur (HS), le circuit (16) commute temporairement vers le mode haute puissance pour actionner l'obturateur (SH). Si la carte (C) est introduite manuellement plus loin jusqu'au point où la seconde bande magnétique (M5) passe par le senseur (HS), et seulement dans ce cas, le circuit (16) commute à nouveau vers le mode haute puissance pour la durée d'une opération pendant laquelle le dispositif déplace la carte et traite ses données magnétiques.

Title: Coating material for lenses.
Inventor: PERKINS PETER GRAHAM
IPC: G02B1/10
Filed: 1985-05-24
Abstract: A material particularly used for protecting a lens surface against scratching comprises a solution containing nitrocellulose in solvent the nitrocellulose being present in the solvent in the range 2.5% to 3.8% by weight. When the material is applied to a lens a coating adheres to the lens in which nitrocellulose is the principal constituent. This coating protects the lens against scratching during manufacture and enables traditional manufacturing processes to be applied for identifying and marking the focal centre of the lens blank prior to shaping the periphery of the blank because the coating does not disguise the optical properties of the lens.

Abstract: L'enceinte d'élevage de la présente invention permet d'épargner beaucoup de travail au pisciculteur lorsque les cages à filet (4a, 4b) d'une pisciculture en mer doivent être remplacées et nettoyées. A cet égard, une enceinte de pisciculture ou autre comprend une structure de support placée à la surface de l'eau (2a) et à laquelle un filet (4) est attaché pour former une ou plusieurs cages à filet (4a, 4b) formant une ou plusieurs zones d'habitation sous l'eau dans lesquelles vivent les poissons. Selon l'invention, des moyens (5, 6, 7) sont prévus et servent à changer le filet (4) pendant que le poisson vit dans lesdites cages à filet (4a, 4b). Dans un mode de réalisation de l'invention, un rouleau à filet (5) est utilisé à chaque extrémité de la structure. Les rouleaux (5) servent à enrouler et dérouler alternativement le filet (4) le long des zones d'habitation (4a, 4b) des poissons, permettant de rincer simultanément le filet (4) dans la zone des rouleaux à filet (5). De cette manière, un filet propre (4) pour les cages (4a, 4b) est toujours stocké et les cages peuvent être remplacées sans avoir à déplacer les poissons (2b). Pour empêcher que le filet ne remonte vers la surface (2a) dans les zones où il forme les cages à filet (4a, 4b), la structure comprend des moyens de guidage (6) montés sur des coulisses réglables (7). La structure comprend une partie (1, 2) s'étendant vers le bas dans la mer dans la zone du filet pour supprimer le mouvement des vagues et empêcher les corps étrangers et la glace de pénétrer dans les cages à filet (4a, 4b).

Abstract: Un récepteur à large bande passante servant à convertir un signal d'entrée de haute fréquence (36) en des impulsions de sortie (50) produit l'expansion de la largeur d'une impulsion de sortie (50) pour permettre le traitement des impulsions à l'aide d'un équipement conventionnel à des cadences de traitement plus lentes. Un oscillateur local de balayage (42) module en fréquence le signal d'entrée (36) pour créer un signal modulé en fréquence qui est comprimé en une impulsion par une ligne de retard à dispersion (40). La largeur de l'impulsion de sortie (50) est augmentée en produisant une non-correspondance ou différence dans les pentes fréquence/temps (52, 54) de l'oscillateur et de la ligne de retard à dispersion. La différence de pente est obtenue à l'aide d'un générateur de fonction (58, 68) qui maintient la pente fréquence/temps (52) de l'oscillateur local de balayage (42) à une valeur différente de celle produite par la ligne de retard à dispersion (40).
