IPC: G01L1/24
Filed: 1988-02-26
Abstract: An optical sensor includes an optical fibre (1), a polychromatic light source (2) and a detector (3). The optical fibre is disposed such that a change in the parameter to be measured causes a movement of the fibre to vary the amount of microbending such that the portion of the polychromatic light which is no longer constrained within the fibre is varied. The detector (3) detects the intensity of the polychromatic light transmitted by the optical fibre (1) at a plurality of different wavelengths, and a microprocessor (6) interprets the output of the detector (3) in terms of the parameter to be measured.

Abstract: A process for producing a self-restoring over­current protective device by the grafting method, wherein an organic peroxide is added to colloidal graphite, at least one kind of carbon black selected from among acetylene black, Ketjen black and furnace black having a high structure, and at least one kind of crystalline polyner substance while heating and milling the latter three components, and the heated mixture having a high viscosity is forcibly milled, whereby the organic peroxide is reacted with the polymer substance to give unpaired electrons to the polymer substance to thereby form polymer radicals. Subsequently, the formed polymer radicals are preferentially grafted onto the above-mentioned graphite and carbon black to form a milled mass wherein the grafting products are homogeneously dispersed in the above-mentioned polymer substance. The milled mass is molded into a predetermined shape while it still retains thermoplasticity. Subsequently, the above-mentioned organic peroxide not involved in the formation of the above-mentioned polymer radicals is thermally decomposed to crosslink the above-mentioned grafting products and polymer substance, whereby a molding having a three-dimensional network structure is obtained.

Abstract: A color correction method for a video graphics system defines a region of color space within which target objects to be corrected lie. The region is defined automatically by positioning a target box within a representative portion of a target object within a video picture and computing from the pixels within the target box a range of color parameters which include the target object. A desired color for the target object is selected, and all pixels which are both within the video picture or a selected portion thereof and also within the defined region of color space are changed accordingly. Anti-aliasing is provided by scanning an area surrounding each pixel to determine the number pixels within the area which are within the defined region, and changing the color of each pixel according to the ratio of the number of pixels which lie within the defined region and the total number of pixels within the area.

Abstract: A disposable safety syringe (1), such as a dental syringe, comprising a syringe cylinder (2) having proximal and distal ends, a pre-filled fluid medication cartridge (20) movable through the cylinder, and a double-ended hypodermic needle cannula (18) extending through and being retained at the distal end of the cylinder between a pair of rotatable jaws (14,16). A piston (26) is movable distally through the cartridge for expulsing the fluid contents via the needle cannula and for engaging one end of the cannula. The cartridge (20) is moved through the cylinder and into contact with the needle retaining jaws (14,16) to cause said jaws to be rotated relative to the needle cannula. Accordingly, the jaws are moved out of engagement with the needle cannula. The piston (26) is then moved proximally through the medication cartridge (20) for correspondingly retracting the needle cannula (18) past the jaws (14,16) and into the empty medication cartridge, wherein the cannula (18) is completely shielded and irretrievably located. The syringe (1) is now rendered non-reusable and suitable for a safe disposal without subjecting health care workers to an accidental needle strike as a consequence of a careless handling or cutting of the cannula.

Abstract: System and method for reducing data loss in a database system during I/O errors and power failure during non-atomic writes to media in a transaction management system using write-ahead logging protocol. A recovery log is written during forward processing. On system restart processing, the log is traversed and a REDO executed. Recovery is effected from detected incomplete log writes or log write failures and uncommitted transactions are undone. A technique is provided in which files having I/O errors are identified, whereby subsequent restart operations are prevented from accessing these files. In one embodiment index files with such error are renamed, serving to indicate that corresponding original files contain errors, and the error index files are automatically rebuilt whereby I/O error on the files causes no data loss. The index file rebuild does not invalidate access plans related to the failed index.

Abstract: Blood clots and myocardial infarction can be treated by administering a hapten-binding molecule capable of preventing inhibition of plasmin by endogenous alpha-2-antiplasmin. The hapten-binding molecule may be co-administered with a thrombolytic agent capable of either dissolving fibrin-platelet clots or inhibiting their formation. This leads to increased clot lysis while minimizing fibrinogen breakdown and preventing the reocclusion of the affected coronary artery, even in the absence of heparin and when the concentration of thrombolytic agent is lower than that required by other potential therapies.

Abstract: A method for contraction annealing niobium-tin wire is disclosed. An improved niobium-tin wire is provided by loosely winding the wire on a mandrel, or by coiling the wire on a circumferentially retractile mandrel, and contraction annealing the wire without reaction-forming substantial amounts of Nb₃Sn. Such contraction annealing allows the wire to contract in length unconstrained thereby preventing the formation of internal tensile stresses in the wire and its surrounding insulation. Prevention of internal stresses in the wire greatly reduces the susceptibility of the wire to breakage, cracking, sintering, shorting, tin leakage, or sub­stantial shifting of the wire from desired wrap positions when it is reaction annealed to form the brittle super­conducting intermetallic compound Nb₃Sn.
