Title: Adjustable downhole tool
Inventor: RUSSELL MARK ALEXANDER
IPC: E21B23/04
Filed: 2005-01-25
Granted: 2011-01-11
Abstract: An adjustable down-hole tool, for example a drill-string stabiliser (10), comprises a body (12) having a through bore (16). A mandrel (18) is rotationally fixed but axially movable in the body, the mandrel being movable by fluid pressure in the tool against the action of a first return spring (44) between a first, deactivated position and a second activated position. A sleeve (66) is between shoulders (68, 69) on the body and mandrel. Castellations (l8a,b, 69a,b) are on the body and facing edge or edges of the sleeve so that, when the castellations are in phase, the mandrel is prevented from travelling from said first to second position, and when they are out of phase they interdigitate and the mandrel is not prevented from travelling from said first to second position. A control piston (36) is slidable in the mandrel, being movable by fluid pressure in the tool against the action of a second return spring (50). The piston is axially slidable with respect to the mandrel. A circumferential barrel cam (56) is defined on the piston, a cam follower (58) being disposed in the mandrel but within the confines of the barrel cam so that axial movement of the piston with respect to the mandrel results in corresponding rotation of the piston with respect to the mandrel. Gears (61) in the barrel transmit rotation of the piston to the sleeve to move the sleeve between said activated and deactivated positions.

Abstract: A method for selectively printing different messages on labels printed by an in-store scale involves providing an in-store scale including a label printing mechanism with a supply of labels and a communications link for receiving information from a site external to the store. The scale label printing mechanism is configured in a first state and, during the first state, simultaneous printing of two types of information on a first label takes place. In particular, both (i) product information for a specified product to which the first label will be applied and (ii) a first message pertaining to a product which is different than the specified product to which the first label will be applied, are printed on the first label. The in-store scale receives a message control signal via the communications link which configures the scale label printing mechanism in a second state. During the second state, simultaneous printing of two types of information on a second label takes place. In particular, both (i) product information for a specified product to which the second label will be applied and (ii) a second message, different than the first message, and also pertaining to a product which is different than the specified product to which the second label will be applied, are printed on the second label.

Chaque ensemble de service consiste en un groupement arbitraire d'un ou plusieurs paramètres de service de réseau et est conçu soit pour un VLAN, soit pour un hôte IP mobile indirect. Quand une station radio désire s'associer à un point d'accès, elle envoie un message à ces point d'accès, ce message contenant un SSID. Le point d'accès met ensuite en correspondance cet SSID avec un ensemble de services et associe le WSTA soit avec un réseau secondaire domestique, soit avec un VLAN en fonction du SSID. La configuration locale de l'ensemble de services peut rendre différent le VLAN défectueux et le réseau secondaire domestique pour un WSTA pour chaque AP rencontré par ce WSTA. Un serveur de sécurité possède une configuration de liste des SSID autorisés pour chaque station radio afin d'empêcher l'accès illicite à un VLAN ou à un réseau secondaire domestique.

Abstract: The invention relates to a method for sealing a fibre-based material (1, 4) to a counter-surface to be bonded to it by melting polymer present at the sealing point. In accordance with the invention, the sealing is performed by directing a laser beam (8) through the fibre layer (4) of the material to a radiation-absorbing pigment disposed in the sealing area (9), with the absorption heat melting the polymer (5) and generating the sealing. The method allows sealing of plastic-coated paper or board to itself, to another plastic counter-surface or also to paper or board without any plastic coating. It is also possible to seal uncoated paper or board to paper or board containing plastic, such as plastic-coated paper or board, or to a plastic film. The absorptive pigment, e.g. carbon black, may be admixed in the plastic coating of the board or paper or the plastic film formed on the counter-surface, or the pigment may be located on the surface of the material to be sealed or its fibre layer, or on the counter-surface to which the material is sealed, e.g. as a component of printing ink applied to the counter-surface.
