Patent EP-0305082-A1 (EP)
Inventor: COOL WILHELM ANDREAS
IPC: B65D19/00
Filed: 1988-08-10
Abstract: A pallet is disclosed which comprises upper and lower stackable components. Each component (10) comprises a deck and connectors (20) which stand proud of the deck. The connectors of the upper deck protrude downwardly and the connectors of the lower deck protrude upwardly. The two sets of connectors co-operate with one another to form columns which space the decks vertically from one another. The connectors include interlocking formations (22, 24) which mesh and prevent the components moving relatively to one another in the horizontal direction. The meshing formations can be spigots and sockets. Alternatively, each formation can be a pair of wedges which are diametrically opposed to one another and on the exposed face of its connector. The raised wedges are arranged with their apices directed towards one another and each has a radially outer face which is 90° degrees in extent. When the pallet components are presented to one another with one of them inverted, the sockets receive the spigots (in the first constructional form) and the wedges mesh (in the second constructional form).

Title: Protic solvent in a dehydrohalogenation process.
Inventor: SOWERBY ROGER LEE
IPC: C10M155/04
Filed: 1988-03-11
Abstract: A process for producing a sulfurized olefin product substantially free of ash containing waste is disclosed. The process involves dehydrohalogenation of an olefin/sulfur halide complex by contacting the complex with a protic solvent in the absence of any metal ion. The process allows for the solvolytic dehydrohalogenation of the complex. The sulfurized olefin product obtained is isolated and may be subjected to further processing to remove any remaining halides. The resulting sulfurized olefin is a useful additive in lubricating oils.

Abstract: Apparatus for processing a first signal representing a colour component of a pixel of an image in which the signal defines the value of the colour component as one of a first set of values defining a first scale of colour component values. The apparatus comprises a first Look-up Table (LUT) (2) addressed by the colour component value for generating a second signal representing a modified colour component value chosen from a set of modified colour component values defining a second scale coarser than the first scale. An adjustment circuit (3; 7-9) comprises a memory (3,9) in which at least two sets of adjustment data are stored, each set being associated with a respective dither threshold representing respective differences, hereinafter referred to as quantisation errors, between the first and second signals when compared on the first scale of colour component values, the data of each set defining an adjustment instruction for each possible quantisation error, the adjustment instruction being related to the difference between the quantisation error and the respective dither threshold. The adjustment circuit means receives the first signal so that the memory is addressed by a signal related to the quantisation error and related to the position of the pixel in the image so as to generate an adjustment control signal associated with the quantisation error and the dither threshold corresponding to the first signal pixel. A modifying circuit (5) is responsive to the adjustment control signal generated by the adjustment circuit to adjust the second signal to generate a final output signal representing one of the second set of the colour component values.

Abstract: Un transducteur acoustique (102) comprend une surface courbe (102) adaptée aux surfaces interne (108) ou externe d'une surface cible (100), telles que des tiges cylindriques de forage. Une séquence d'impulsions d'excitation provoque l'émission par le transducteur d'une série d'impulsions de haute-fréquence (308) vers les tiges tubulaires. On détermine les caractéristiques des surfaces tubulaires, y compris la localisation, la superficie et la profondeur de tout creux dû à la corrosion des surfaces tubulaires, sur la base d'une forme d'onde d'écho pleine. Un Système Expert normalisé analyse la forme d'onde pleine des impulsions d'écho réfléchies par les tiges tubulaires afin de déterminer les caractéristiques les plus probables des surfaces ayant produit la forme d'onde d'écho pleine. Plus spécifiquement, le Système Expert utilise des connaissances au sujet des propriétés acoustiques du milieu cible et des contraintes sélectionnées par un expert afin de déterminer quelles structures de signaux sont significatives et quelles structures de signaux sont trompeuses. L'invention concerne également le prétraitement et la transmission d'informations. Elle réduit la quantité absolue d'informations transmises sans réduire la quantité transmise d'informations significatives. Elle permet de transmettre davantage d'informations significatives que les systèmes conventionnels de transmission. Elle permet également de diminuer le traitement d'informations à la destination.
