Abstract: Protein derivatives of formula (1)  A-CO-N(R<1>)N(R<2>)-Z<1>- @-Z<2>-N(R<3>)NHR<4>      (1)   wherein A-CO is the residue of a protein or peptide A-CO2H (especially where -CO2H is the C-terminal carboxyl group of the protein or peptide); R<1>, R<2>, R<3> and R<4>, which may be the same or different, and which may be present or absent, is each a spacer group, X is an oxygen or sulphur atom; and the salts thereof. The compounds may be prepared by a condensation reaction, especially in the presence of an enzyme capable of catalysing the formation of a peptide bond. The compounds may be used to form protein conjugates in which a group of interest such as another protein or peptide or an effector or reporter group is coupled to the protein through a -N(R<1>)N(R<2>)-Z<1>-C(=X)-Z<2> -N(R<3>)N= group.

Abstract: A distribution arrangement for optical fibre comprising a branched coupling array (1) and a plurality of splice organisers (2) for storing splices associated with connections to the coupling array. Each fibre connected to the array passes through a manifold block (8) that is provided with a plurality of capillaries extending to the splice organisers. Fibres from other parts of the network also pass through the manifold and into capillaries for conduction to the splice organisers where they are connected to a respective fibre from the coupling array. Preferably the array (1) has alternative winding routes for fibre tails extending from individual couplers within the array to facilitate multiple splice attempts. A preferred splice organiser comprises an enclosure into which coiled fibre loops are introduced and permitted to expand so that they are retained by the resilience of the fibre itself.

Abstract: The device is used for cutting tiles and plates and possesses an elongate bearing part (1), on the narrow sides of which brackets (4, 5) are arranged which carry guides (8) extending parallel to the longitudinal extent of the bearing part (1) and arranged above the latter. A carriage (9) is mounted to be displaceable along these guides, on which carriage is pivotably mounted a lever arm (10) which carries the cutting tool and, if appropriate, a breaking tool (15). The bearing part (1) is formed from an extruded, flat box profile (34), which is designed in mirror symmetry about its vertical longitudinal median plane (17). At each of its two narrow end sides (18) it has a groove (19) which extends lengthwise, and is laterally open and undercut. This groove (19) is adjoined, towards the vertical longitudinal median plane (17), by a drilled channel (20) in each case. The longitudinal axis of the drilled channel (20) and the median plane of the groove (19) lie in the horizontal median plane (21) of the flat box profile (34). The lateral grooves (19) of the flat box profile (34) accommodate, in a twist-proof manner, heads (32) of laterally projecting threaded bolts (31). Widening profiles (30) which are flanged laterally onto the box profile (34) are secured by means of these threaded bolts (31). <IMAGE>

Abstract: A method of completing a well includes injecting a consolidatable resin coated particulate slurry through production casing set in the production zone of a producing formation such that said slurry flows into an annulus formed between the casing and the wellbore to form a zone of high conductivity communicating with said casing and said formation and concurrently with such injection creating at least one fracture in said formation with said slurry; permitting said consolidatable resin to harden; and perforating the casing and consolidated zone. Prior to injection of the particulate slurry, a first fluid may be introduced through the casing into the annulus at such a rate that the first fluid removes undesired debris and mudcake from the wall of the wellbore.

Abstract: Un procédé permet de contrôler la manoeuvrabilité d'une soupape d'aération d'un réservoir à travers laquelle une quantité supplémentaire d'air chargé de vapeurs de carburant peut être introduite dans la zone d'aspiration d'un moteur à combustion interne. Afin de mettre en ÷uvre ce procédé, on mesure, dans la zone de la soupape d'aération du réservoir, des valeurs qui varient lorsqu'un certain débit s'écoule à travers celle-ci. On évalue de préférence des différences entre ces valeurs avant et après la commande de la soupape d'aération du réservoir. En cas de besoin, par exemple lorsque la sensibilité des capteurs utilisés le requiert, le contrôle peut dépendre de la pression dans la zone d'aspiration.

Abstract: A voltage-to-digital converter comprising a storage circuit for providing a storage capacitance with a plurality of selectable magnitudes. The storage circuit provides a charge output representative of applied voltage input signals and the selected capacitive magnitude. A charge accumulation circuit is coupled to the charge output. The total charge accumulated is proportional to the integral of the amount of charge discharged from the storage circuit. The charge accumulation circuit provides a balance output representative of a comparison of the accumulated charge and a reference charge. A control circuit is coupled to the balance output for providing feedback signals as functions of the balance output for periodically charging and discharging the storage capacitance whereby a first sequence of charge packets is provided on the charge output for driving the accumulation of charge toward the reference within a first set of limits when a first capacitive magnitude is selected in the storage circuit and whereby a second sequence of charge packets is provided on the charge output for driving the accumulation of charge toward the reference charge within a second set of limits when a second capacitive magnitude is selected in the storage circuit. A calculation circuit is coupled to the feedback circuit for counting the number of charged packets generated in a measurement cycle. An output circuit provides an output indicative of the voltage input signals as a function of the number of packets counted.

Abstract: The invention concerns a system for the generation of magnetic gradient fields which intermittently overlap the static magnetic field of a nuclear-spin tomograph. The system has at least one pair of gradient coils which are fed from a mains-powered device, through which current flows in series when in operation and which generate, in a given volume of material under examination, a gradient magnetic field which varies at least approximately in linear fashion with position in one direction. The system is characterized by the fact that each gradient coil (A, B) has a set of windings with at least a first winding zone (S1) and a set of windings with at least a second winding zone (S2) which have separate connections (16, 17; 18, 19), such that the winding zones can be easily connected to each other, and disconnected in a different way. This enables the user to alter the properties of the gradient system.

Abstract: The present invention relates to the manufacture of abrasion-proof plates. The abrasion-proof surface of the plate is composed of external face 5 of a layer of composite material based on spherical grains of melted tungsten carbide bonded in a soldering alloy. Grinding surface 5 has a smooth and even mould finish. The abrasion-proof layer contains a compact, regular and essentially uniform random distribution of tungsten carbide grains. Surface 5 is made by moulding: the tungsten carbide grains are inserted between the mould walls and core 2 of the part, and the soldering alloy is made to infiltrate between the powder grains, core 2 and the mould by increasing the temperature. The invention allows a significant increase in the abrasion resistance of grinding plates.

Abstract: The present invention provides for an equalization method that forms the nucleus of a receiver for digital cellular mobile telephones. A number of distinct aspects of the design are considered novel, including non-real time operation that permits and exploits "time-reversed" equalization to significantly enhance bit error rate performance. The present invention employs the use of a maximum likelihood sequence estimation process. It uses variable coefficient least mean square tracking during estimation of the transmission channel's impulse response. It also employs the use of integrated symbol timing adjustment and carrier tracking algorithms. Time-reversed operation further enhances performance and permits implementation with reasonable complexity of a standards compliant mobile receiver.
