Inventor: AOKI NAMITO
IPC: B60C11/12
Filed: 1993-09-29
Abstract: A pneumatic tire comprises a plurality of blocks. Each of the blocks has a set of two sipes extending substantially in a transverse direction of the tire. The sipes divide the block into a narrow area formed therebetween and wide areas located so as to sandwich the narrow area. A length of one side end of at least one of the wide areas in a circumferential direction of the tire is different from a length of another side end of that wide area in the circumferential direction of the tire.

Patent CA-2128315-A1 (CA)
Title: Apparatus and method of sensing using distributed excitation of an optical guidedwave structure by ambient radiation
Inventor: MEASURES RAYMOND M
IPC: G01N21/64
Filed: 1994-07-18
Abstract: Distributed transverse excitation of an optical guidedwave structure by means of ambient radiation from a natural or man made source avoids the need to connect a source through one end of the device. This permits a wide range of sensing with significant improvement in the ease of installation and lower costs than conventional guidedwave sensors. In this type of sensor the local environment, the state of the sensor, or some measurand of interest can modulate its output optical power by modifying the transmission of radiant energy through the device. A unique aspect of transverse excitation is that distributed sensing of the local environment is also possible through direct control of the level of excitation. The optical guidedwave structure can thus be made to sense its state, or its local environment. When transverse distributed excitation with low level ambient radiation is combined with visual inspection the sensor becomes "self-contained", extremely simple and very low cost.

Title: Process for tarsia-working of marble, granite, etc.
Inventor: PICCOLI EMILIO
IPC: B28D1/30
Filed: 1992-10-16
Abstract: The process according to the invention comprises a first step in which the material which is intended to form the support (12) for a tarsia decoration is worked by means of a digitally controlled (DC) milling machine which is programmed in such a way as to obtain, by means of diamond-tools acting on the surface to be decorated, areas which reproduce, by means of grooves (14) and notches, a decoration pattern. A slab (11) constituted by the material forming the decoration is then worked by means of a DC milling machine in order to form on the slab, in relief, a decoration pattern. Said slab (11) is then placed on the material (12) to be decorated, in the grooves of which a suitable bonding agent is previously laid down, in such a way as the reliefs are embedded in said grooves. Then, the upper portion of such a sandwich is removed, normally by means of a longitudinal cut, thereby freeing the decorated material, which is successively smoothed and polished.

IPC: F16J15/3236
Filed: 1994-08-29
Abstract: A rod or piston seal with a seal body of polymeric material has a seal surface for engagement with a relatively movable surface to be sealed which seal surface is interrupted in the direction of movement by at last two circumferentially extending grooves that are positioned at a selected distance from each other. The distance between adjacent grooves is respectively covered by an intermediate web.

Title: Rapid extraction of ciguatoxin from contaminated tissues
Inventor: PARK DOUGLAS L
IPC: G01N33/538
Filed: 1993-04-27
Abstract: The present invention relates to methods for the rapid extraction of ciguatoxins from tissue samples. In one embodiment, a tissue sample is extracted with a first solvent to solubilize and extract ciguatoxin from the sample. A second solvent, which is not soluble in the first solvent and which extracts contaminants but not ciguatoxin, is then added. The phases formed by the first and second solvents are separated, and the first solvent phase is collected. The first solvent is evaporated from the first solvent phase to produce a residue which is resuspended in a third solvent. A  fourth solvent, which is not soluble in the third solvent and which extracts contaminants but not ciguatoxin, is added to the third solvent/residue mixture. The phases formed by the third and fourth solvents are separated, and the third solvent phase, which comprises ciguatoxin, is collected. In a second embodiment, a sample is applied to a coupled antibody-resin. The coupled antibody-resin is washed with a solution to remove unbound material, but not ciguatoxin, from the coupled antibody-resin, and ciguatoxin is then eluted from the coupled antibody-resin.
