Abstract: A pressure regulating valve for controlling an upstream fluid pressure in relation to a reference pressure by regulating the fluid quantity let through the valve, comprising a housing (1) having an upstream inlet (2) and a downstream outlet (3) for the fluid, a pressure-sensitive element (5) for sensing the pressure difference between the upstream pressure and the reference pressure, and a spring-loaded regulating piston (7) which, in cooperation with a seat (8), is arranged to regulate a flow passage (9) between the inlet (2) and the outlet (3), the piston (7) being operatively connected to the pressure-sensitive element (5), to change its position relative to the seat (8) in accordance with the position of the pressure-sensitive element (5).  The regulating piston (7) is slidably arranged on the outside of a guide sleeve (10) having openings (11) for the flow of fluid from the flow passage (9) to the outlet (3). Further, the valve comprises a chamber (15) defined between an end surface (13) of the guide sleeve (10) and an inner end surface (14) of the piston (7), and a pilot body (16) which is mechanically coupled to the pressure-sensitive element (5) and is arranged to open ducts (20-23) for supply of fluid from the inlet (2) to the chamber (15) or delivery of fluid from the chamber (15) to the outlet (3) dependent on the position of the pilot body (16) relative to the regulating piston (7), so that the piston changes its position dependent on the chamber volume and thereby in accurate correspondence with the position of the pressure-sensitive element (5).

Abstract: An automated analysis method and tool (50) for a digitally imaged financial item (58) can digitally recognize a plurality of characters across an area of a digital image containing character indicia (54) at predetermined positions in the area and also possibly containing non-character indicia (54) in the area. This finds exemplification in an automated check processing method and check sorting system in which a check's MICR line that has been read and interpreted as invalid can be digitally analyzed (66), via a digital image (56) of the check, to identify MICR characters that could not be validly read or interpreted by the conventional MICR processing equipment. This includes digitally applying character recognition processing to an invalidated MICR line in a digital image of the financial item (e.g., a check). Previously invalidated MICR line data can then be corrected.

Title: Particulate material handling systems
Inventor: WATSON BRET
IPC: B65G15/60
Filed: 2003-03-10
Granted: 2004-08-10
Abstract: The particulate material handling system comprises a tube, an endless belt that passes through the tube and returns outside of the tube, and a flighting that is suspended a predetermined distance from the belt through the entire length of the tube. The distance may be varied for the various materials being handled. An intake hopper is mounted at one end of the tube for receiving the material to be moved and a discharge spout is mounted at the other end of the tube for discharging the material from the tube. The endless belt and flighting are driven such that their speed may be varied and such that their relative speeds are synchronized to drive the material at substantially the same speed whether it is being carried by the belt or the flighting.   The combination of the belt and the flighting drives the material through the tube, minimizing damage to the material, which may be granular fertilizer, pulse crops, grains or other particulate material.

Title: Power interrupt system for a refrigerated appliance
Inventor: MILLER ALVIN V
IPC: G01K3/00
Filed: 2003-03-14
Granted: 2009-06-23
Abstract: A refrigerated appliance includes a power interrupt system for detecting an out-of-range temperature condition in a fresh food or freezer compartment after a power interruption. The power interrupt system includes a central processor including a memory storage module and a plurality of temperature sensors. In operation, the power interrupt system compares sensed temperature values with stored temperature variables. If, after a power interruption, a compartment temperature exceeds a stored temperature variable by a defined amount, an over-temperature flag is triggered. Preferably, a display unit flashes an indication of the highest temperature reached by each compartment intermittently with the current compartment temperatures and an indication that a power interruption has occured. In this manner, a consumer can make an informed determination whether food stored within the appliance has been exposed to temperatures high enough to cause spoilage.

Title: Drillhole blasting
Inventor: HEINKE NILS ALBERTO
IPC: E21C/
Filed: 2001-11-19
Granted: 2009-06-02
Abstract: A blasting arrangement (10) includes drillholes (30) in a rock mass (20). Blind ends (32) are drilled to a desired level and, if necessary, are adjust ed as shown at (62) to said level. Each hole (30) is plugged by means of a plug (42), which is protected by non flammable buffer material (44), at a level (40) spaced from the end (32). Explosive (50) is charged above the level (40 ) and the hole is tamped, shown at (60). The holes are detonated desirably by detonators (52), forcing the plugs (42) downwardly and compressing air in chambers (34) above the ends (32). The weakest part of each hole, around the end (32), is split causing a three dimensional zone of weakness at the level of the ends (32). Air forced into the zone of weakness causes a fracture zon e (70) at that level, inhibiting propagation of blasting shock waves and protecting the material underneath the level of the ends (32).

Abstract: L'invention porte sur une attelle de pied permettant de prévenir et de guérir une fasciite plantaire, qui maintient le pied, et par le fait même, le fascia plantaire, avec un certain degré de dorsiflexion choisi au préalable. L'attelle de pied comprend une plaque destinée au soutien du pied, un support latéral entourant la partie inférieure de la jambe doté d'une languette amovible permettant d'attacher le support à la jambe et une partie enveloppant le pied. Une semelle souple peut être ajoutée pour amortir le pied contre la plaque de soutien. La partie enveloppante, la semelle et la plaque de soutien sont confortables et offrent une sensation s'apparentant au port d'une pantoufle. En outre, l'attelle de pied est particulièrement bien adapté à une utilisation la nuit, car elle est légère et sa configuration ouverte permet à la personne d'adopter librement différentes positions pendant son sommeil, ce qui favorise le repos. De plus, le fait que le support soit latéral empêche les parties rigides de l'attelle de notamment frotter ou frapper accidentellement l'autre jambe.

Abstract: L'invention concerne des compositions antimicrobiennes renfermant des complexes synergiques à base d'octoxyglycérine et d'au moins un autre agent antimicrobien dans des préparations, qui sont plus efficaces que les compositions actuellement disponibles, sans toutefois être très irritantes pour une peau normale. Dans certains modes de réalisation, l'irritation de la peau peut être réduite au minimum grâce à de faibles concentrations d'agents antimicrobiens et/ou de composés apaisants, tels que le zinc. Les modes de réalisation préférés de l'invention concernent des complexes à base d'octoxyglycérine, d'un composé quaternaire et d'au moins un autre agent antimicrobien. Il semblerait, sans que cela ait un lien avec une théorie quelconque, que l'efficacité antimicrobienne inattendue de complexes à base d'octoxyglycérine résulte de l'augmentation de la perméabilité des microbes aux agents antimicrobiens due à l'octoxyglycérine. L'invention concerne également une composition de gel hydroalcoolique à base d'alcool, d'eau, d'un hydrogel et d'un émollient ou d'un émulsifiant. Cette composition a une viscosité inférieure à 2000 centipoises à une température comprise entre 20 et 40 ·C. Cette composition de gel hydroalcoolique doux peut être combinée avec un polymère siliconé, un solvant émollient, un agent épaississant et un agent antimicrobien et a une efficacité antimicrobienne rapide et durable.
