Patent EP-0313679-B1 (EP)
Inventor: COLLINS IMACK L
IPC: A01D34/416

Granted: 1996-05-15
Abstract: Apparatus for cutting vegetation with a rotatable head carrying a non-metallic cutting line (31) extended into a cutting plane. As the line extension decreases from an established preset length an actuator in the head permits additional line to be extended automatically from a supply source within the head. The actuator imposes a back pressure (F3) against the line of magnitude correlated to the sensed pull tension wanting to extend the line outward of the head. After the cutting line length is extended to its restored original preset length, the actuator in response to the operational forces imposed thereon secures the cutting line against further extension until a subsequent decrease in line extension is incurred. In one embodiment an inertial drag brake (68) is activated during the course of line feedout and is deactivated after the length of cutting line has been fully restored.

Abstract: A roofing slab (1) has a roof lead-through in the form of a pipe (2) of adjustable inclination which extends from beneath the roofing slab to a point above it via a correspondingly dimensioned passage hole provided in the region of the vertex of a dome of the slab. The dome has a dome-shaped upper side and a form-fitting hood part (5) associated with the pipe. The hood part rests on the dome in secured fashion by an urging of the pipe, in the region of the lower side of the roofing slab, towards the roofing slab. An advantage from a structural and mounting standpoint is that the pipe (2) be formed in two parts with a place of coupling (K) above the hood part (5). In this way the pipe part (2') which serves the purpose in view can be very easily attached from the outside.

Abstract: The device is for removing medium-viscous and highly viscous media from containers and barrels and dispensing them precisely. It has a follow-on plate 2 which is pressed onto the medium to be conveyed. Mounted on the follow-on plate 2 is the housing 6 of a cup-piston-type pump, the housing having two chambers 7, 8 sealed off from each other. The two chambers 7, 8 are connected via a positive-control inlet valve 11 and a further positive-control outlet valve 18 is fitted to the outlet 17. The medium is conveyed by means of the cup piston 9 into the dispensing chamber 8, and the valve 11 closes as soon as the necessary filling volume is reached. In the dispensing chamber 8, the medium is compressed to the required conveying pressure and the material is ejected by opening the outlet valve 18.

Abstract: An improved reaction chamber for use in an epitaxial deposition process for processing a single wafer-at-a-time includes a cold-wall reactor having a substantially rectangular cross-section. The cross-sectional area of the reaction chamber is substantially reduced to increase the efficiency of the system. Apparatus is provided to maintain the wall temperature within a predetermined range for insuring that only readily cleanable deposits are formed. The susceptor assembly is mounted within a wall distending vertically downward from the bottom of the chamber or within a second portion of a duel height chamber having a greater cross-sectional area. A method and apparatus is provided for supplying purge gas to prevent the flow of reactant gas and the undesirable deposits resulting therefrom from forming beneath the susceptor. The flow of reactant gas beneath the susceptor is controlled by a quartz plate for narrowing the gap between the input end of the reactor and the susceptor and for simultaneously shaping the gap to provide a desired velocity profile. Alternatively, a horizontal extension of the floor of the cavity can be provided to perform substantially the identical function. Furthermore, two types of reactant gas injectors can be used for controlling the result in velocity profile of the injected gases.

Abstract: Sont décrits un appareil assorti de procédés d'utilisation, pour localiser des bords contenus à l'intérieur de chaque ligne de balayage d'une image vidéo balayée et également pour localiser des limites horizontales (bords d'attaque et de fuite) d'une portion d'un document contenue à l'intérieur de la ligne de balayage. Plus précisément, cet appareil fournit tout d'abord une valeur de fond représentative d'une densité de fond dans une image balayée et associée à une valeur de pixel d'entrée. Si cette valeur de fond excède une première valeur de référence, un premier signal est produit. Si la valeur de pixel d'entrée excède une deuxième valeur de référence, un deuxième signal est produit. Une transition de bord est d'abord détectée sur la base d'une combinaison logique prédéfinie des premier et deuxième signaux. Si une telle transition a été détectée, telle qu'un bord d'attaque ou de fuite soit dans les valeurs de pixel d'entrée soit dans la densité de fond, un circuit de commande, mis en oeuvre à titre d'exemple au moyen d'un circuit logique à réseau programmé et de divers compteurs, détermine si la transition de bord est associée à un bord d'attaque ou de fuite correct, c'est-à-dire si la transition elle-même est suivie d'un nombre pédéterminé de valeurs de pixel similaires. Si un bord d'attaque ou de fuite correct est détecté, le circuit de commande produit alors des signaux appropriés pour mémoriser comme bord d'attaque ou de fuite l'adresse de pixel horizontal de la valeur de pixel d'entrée. En outre, après détermination de tous les bords d'attaque et de fuite pour une ligne en cours de balayage, la paire de bords d'attaque/fuite présentant le plus large espacement est sélectionnée comme constituant les bords d'attaque et de fuite indiqués (limites horizontales) d'une portion d'un document exploré située à l'intérieur de la ligne en cours de balayage.

Abstract: An aerating device, which operates independently of its position, for casings in which, for example, electrical circuits are housed, consists mainly of a hose-diaphragm piece, preferably of porous PTFE. The hose-diaphragm piece is plugged on to a tube connecting piece on the casing. The hose shape avoids water collecting on the porous diaphragm surface and hence hindering the passage of the gas. The porous PTFE used for the hose-diaphragm piece permits gases to pass through, but is at the same time impermeable to water. <IMAGE>

Abstract: Apparatus for preventing the unauthorized detection of the start and end of packets being communicated within a packet switching system. The packet switching system comprises a plurality of packet switching networks that are interconnected by trunks. Each switching network has a number of trunk controllers with each terminating one of the trunks interconnecting that network to other networks. Each controller has an encrypting circuit for only encrypting the flag of each packet before the packet is transmitted on the connected trunk and a decrypting circuit for decrypting the flag of each packet received from the connected trunk. The decrypting circuit on the receiving side of a trunk recovers flag synchronization with the encrypting circuit on the transmitting side of the trunk by the exchange of special packets. Each flag comprises a plurality of bytes. The decrypting circuit can automatically adjust for a predefined number of errors in the flag bytes or a predefined number of flag bytes appearing in the data of a packet.
