Abstract: L'invention concerne des fluides de forage à base d'eau utilisés au cours d'un processus de récupération d'hydrocarbures, tel que le forage, la fracturation, le gravillonnage des crépines ou le reconditionnement. Selon cette invention, ledit fluide de forage comprend un réducteur de filtrat et un matériau de colmatage qui sont intrinsèquement hydrophobes, modifiés de façon hydrophobe ou mouillables à l'huile. Le fluide de forage permet de produire un gâteau de filtration qui, une fois formé, est imperméable lors d'une phase aqueuse, ce qui permet de réduire les pertes de fluide ainsi que les dégâts causés à la formation. Ledit gâteau de filtration est néanmoins simultanément perméable au courant de retour des hydrocarbures au cours du processus de récupération d'hydrocarbures.

Title: Method for drying pasty materials
Inventor: KNOER PETER
IPC: C02F11/12
Filed: 2001-07-30
Abstract: According to the invention, on drying paste-like materials, in particular, clarifier sludge, the material is previously compacted to a dry weight in the range 60 80 % in a drying intermediate stage, such that a relatively low energy requirement results. The transport of the material, both during the pre-drying and after leaving the compacting device (5), is by means of one or two transport belts (3, 4) which are arranged in series in the direction of transport, which permit the through-flow of air and which are enclosed in a common housing (2). As a result, the drying occurs under the same conditions before or after compacting, such that a plant for carrying out the above is easy and thus economical to install. The end product has advantageous properties with regard to density and friability, such that on subsequent handling the development of dust is avoided.

Title: Vehicle remote control
Inventor: PITTET BERTRAND
IPC: G05D1/00
Filed: 2000-10-19
Abstract: The invention concerns a vehicle (1) remotely controlled by a pilot located in a static control station (2). The pilot wears a helmet (4) provided with a display screen (5) wherein he sees an image transmitted from a camera (11) mounted in the vehicle (1). The movements and visual orientations of the pilot's head (helmet 4), that is the direction in which he is looking are transmitted to sensors, and the signals of said sensors are immediately transmitted without delay to the vehicle (1) for directing the video camera (11) into an orientation corresponding to the pilot's visual orientation, and to controls monitoring the vehicle. Said controls directing the camera and said controls monitoring the vehicle without delay considerably improve remote control, thereby making the piloting process so realistic as to give the pilot the impression that he is actually piloting the remotely controlled vehicle, and above all eliminates simulator disease et enables to increase the running speeds of remotely controlled vehicles.

Title: Inductive sensor arrangement and method for detecting of ferrous metal objects
Inventor: GOLDER ROGER
IPC: G01V3/15
Filed: 2002-09-10
Abstract: An inductive sensor arrangement for detecting ferromagnetic or non-ferrous electrically conducting objects hidden in a surrounding medium comprising three field coils arranged in essentially the same geometric plane and adjacently positioned at angular distances of usually 120° from each other around a central axis orthogonal to the plane for generating an alternating magnetic flux by a sequential excitation with an AC-current ramp. The sensor arrangement further comprises three sense coils respectively mounted inside each associated field coil and in an orientation to the axes of each of the field coils such that essentially no voltage is induced in the sensor coils in an environment free of a metallic object. When a ferromagnetic or non-ferrous electrically conducting object approaches the sensor, nine characteristic voltage value sets are produced by the three sense coils which are stored and processed by an algorithmic process for defining a distinct criterion with respect to the position of the hidden metallic object to be located. The sensor arrangement uses a single point measurement to provide an accurate position and depth discrimination of the hidden ferromagnetic or non-ferrous electrically conducting object such as a rebar, a copper pipe in concrete or the like.

Title: Aldehyde donors for stabilizing peroxides in papermaking applications
Inventor: BOROKHOV OLGA
IPC: D21C9/10
Filed: 2001-06-08
Abstract: The present invention is a method of stabilizing hydrogen peroxide in an aqueous solution, such as a circulating water slurry, comprising a peroxide, such as hydrogen peroxide. The aqueous solution may include organic matter.  The method comprises adding an aldehyde donor, such as a methylolhydantoin, to the solution (or slurry). The inventors have discovered that aldehyde donors significantly reduce the decomposition of hydrogen peroxide by catalase and other peroxide decomposing enzymes, which are often present in recycled paper.  As a result, less hydrogen peroxide needs to be added to a solution to effectively bleach organic matter in the solution. Furthermore, aldehyde donors are safe to handle and cost effective. Another embodiment is a method of bleaching recycled papers in a circulating water slurry comprising organic matter. The method comprises adding hydrogen peroxide and an aldehyde donor to the slurry. Yet another embodiment is a method of inhibiting catalase and/or other peroxide decomposing enzymes in an aqueous solution, such as a circulating water slurry, comprising adding an aldehyde donor to the aqueous solution.

Filed: 2003-02-13
Abstract: The invention includes a process and components for making stamping dies from a set of mass produced metal blocks, each machined to size, each with dowel and counter bored holes machined along an Upper and Lower Machining Line. Blocks are of same thickness and width. Each successive block of a set increases in length over the previous block length by either a fixed distance or a variable distance.  Individual blocks can be mounted directly onto the die-set. Machining pattern of holes in each block is such that blocks are ready to be located into position using existing dowel holes and secured onto die-set using existing counter bored holes. All blocks are ready for final custom machining. A set of blocks is designed to accommodate strip widths within a given range. The result is a reduction in die-making time and cost.

Title: Recombinant endothelial cell growth inhibitors derived from a mammalian plasminogen
Inventor: CAO YIHAI
IPC: A61K35/76
Filed: 2001-08-31
Abstract: Proteolytic enzymes are involved in generation of a number of endogenous angiogenesis inhibitors and it has been shown that urokinase-activated plasm in can process plasminogen to release an angiogenesis inhibitor, K1-5 (protease - activated kringles 1-5). However, this proteolytic protein (proteolytic K1-5 ) cannot be secreted (exported) from cells and thus is limited in its application as a therapeutic. The present inventors have now engineered a recombinant protein derived from plasminogen which is folded correctly such that it can be secreted from cells in which it is expressed. The inventors surprisingly found that in order to fold correctly such that it can be secreted, the recombinant protein must comprise a secretory signal peptide a nd a pre-activation peptide derived from plasminogen.
