MANUFACTURING MOULDED BODIES CONTAINING CERAMIC FIBRES A method of manufacturing light moulded bodies includes forming a dispersion of ceramic fibres and flocculating it with a cationic flocculating agent. This flocculated dispersion is then mixed with a dispersion of refractory material with a particle size less than or equal to 0.09mm and an inorganic bonding agent which has been flocculated wit...

A basic instruction for moving a string of bytes in a word has been devised. Because the operations in the instruction are basic, very few variations are necessary to accommodate diversity of lengths and variables. These operations are imbedded in a single code sequence; the compiler can therefore generate exactly the minimum sequence necessary to perform the operations and can precompute many of ...

A method of making a hermetic seal for a solid-state device is disclosed. The device includes a ceramic housing having a cavity for an element such as an image sensor. A cover formed of a transparent material is sealed to the housing to close the cavity. A metallization support is formed on the cover and on the housing. In order to form a hermetic seal at a relative low temperature, a layer of ind...

There are disclosed novel avermectin DELTA 23,24-derivatives (also referred to as 23,24-dehydro compounds). The compounds are prepared by selective dehydration of avermectin A2 or B2 compounds. The avermectin compounds have utility as anti-parasitic agents and compositions for that use are also disclosed. The compounds are also highly potent insecticides against agricultural pests. The DELTA 23...

A method for causing or increasing angiogenesis is described. The method involves administering to a subject, such as a human being in need of angiogenesis an angiogenically effective amount of an angiogenically effective, pharmaceutically acceptable oligosaccharide or mixture of oligosaccharides.

A laser delivery system comprises a light weight hollow boom having a bearing intermediate its ends which permits the distal end of the boom to move longitudinally and rotationally relative to the proximal end of the boom. The bearing supports the distal end without supporting physical contact, e.g. by a layer of fluid. The proximal end of the boom is carried by a boom support for movement about t...

In a semiconductor integrated circuit, power lines or ground lines of a plurality of circuit block (2, to 2n) having equivalent functions are couple via a switch circuit (6, to 6n) to a common main power line or main ground line on a semiconductor integrated circuit chip or semiconductor wafer. The main power line (3) is supplied with power source potential and said main ground line with ground po...

A system for matching images in which characteristic points of an image to be tested for a match, such as a fingerprint, are compared with characteristic points of a master image by attempting to match the distances between pairs of master characteristic points with distances between pairs of live characteristic points, whereby the coordinate system of the test image is not required to be aligned ...

The deviceis connected between two voltage feed lines and includes an information storing circuit having a fuse for storing information by blowing or not blowing the fuse.
