Patent CA-2087869-A1 (CA)
Inventor: COUTURE JOSEPH H D
IPC: G05D1/02
Filed: 1993-01-22
Abstract: Précis Dans un système robotisé mobile, on sait que les déplacements dépendent de la faculté que doit posséder le robot de pouvoir se prendre comme poiint de rééfence donné dans un espace donné. Cependant, à l'état présent de l'art, le robot peut arriver à se prendre comme point de référence au moyen de balises qui quadrillent l'espace où il devra opérer. on système de repérage fait qu'il déduit sa position en captant les signaux (infra rouge, laser, etc.) et qu'ensuite il peut, à partir de cette position se déplacer vers un but qui se situe dans l'espace quadrillé par les balises. Un des problèmes majeurs relatif à ce mode de fonctionnement s'avère le fait qu'il ne peut opérer dans un espace non balisé. Ce qui limite son autonomie. L'invention ici proposée est un système de repérage dans l'espace pour robot mobile qui ne dépend pas de balises. Ce qui se traduit en termes concrets par un gain d'autonomie pour le robot.

Title: Surfactant selection method for the extraction of chemical pollutants from soils
Inventor: PURCELL LAUREN M
IPC: G01N33/24
Filed: 1992-06-22
Abstract: SURFACTANT SELECTION METHOD FOR THE      EXTRACTION OF CHEMICAL POLLUTANTS FROM SOILS                 ABSTRACT OF THE DISCLOSURE     The physics of adhesion are applied to choosing sur-factants that have Lewis acid-base and dispersion force in-teraction values which are required to optimally extract pollutants (10) from soils (12). This application is novel in predicting a surfactant's effectiveness in the removal of toxic contaminants. Additionally, Lewis acid-base and dispersion forces are applied to the selection of a co-sur-factant to improve the adhesion between a surfactant and a pollutant.

Abstract: Theft of a bicycle is discouraged by a locking mechanism (50) in the front headstem (120) that controllably engages the handlebar-attached headstem with the front fork (124) or disengages the headstem and fork for free relative rotation. A shaft (20) attached to the fork and a sleeve (40) attached to the handlebar clamp (44) are connected at a locking junction which is rotatable as a whole in the front journal of the frame. A key operated cam (54) moves a locking roller (70) radially outwardly of the shaft to engage a receptacle (74) in the sleeve for engagement or allows the roller to retract into an aperture (72) for disengagement. The shaft and sleeve have complementary conical tapers (83, 84) axially positioned by a split conical bushing (86). A cylinder lock (50) operates the cam via a key (60) having a substantially tubular configuration (64) with a uniquely configured axial end (136) for positioning lock pins against axial spring pressure.

Inventor: GERTZ DAVID C
IPC: B60R19/00
Filed: 1993-07-29
Abstract: An  energy  absorbing  roadside  crash  barrier includes a scissors linkage having first and second ends. The  scissors  linkage  is  movable  between  an  extended position and a collapsed position.  A mounting element is coupled to the first end of the scissors linkage to mount the scissors linkage to a roadside obstacle.  Deformable energy absorbing elements are mounted to  the  scissors linkage and positioned such that movement of the scissors linkage from  the  extended  to  the  collapsed  positions deforms  the  energy absorbing  elements,  and the  energy absorbing elements thereby progressively resist collapse of the scissors linkage.  A tension member is secured to the scissors linkage to apply a restraining force to hold the scissors linkage in the extended position, until forces tending to collapse the linkage exceed a pre-set range of values.

Title: Air blast high voltage circuit breaker having a reduced syze air compression arc chute
Inventor: DUFOURNET DENIS
IPC: H01H33/90
Filed: 1993-09-27
Abstract: A self-blast circuit breaker comprising a movable assembly including an arc chamber in two parts consisting of a blast chamber (17) and of a compression chamber (18). The two chambers are separated from one another by a crown (9). The compression chamber (18) is closed by a semi-movable piston (11). The circuit breaker is characterised by a means for immobilising the piston during a first part of the movement of the movable contact assembly between a closing position and an opening position and by a means for axially displacing the piston with the movable contact assembly during a second part of this displacement. This makes it possible to reduce the quantity of energy necessary for displacing the movable contact assembly during the opening operation. <IMAGE>

Inventor: CLARE MANAMOHAN
IPC: E03C1/02
Filed: 1994-02-03
Abstract: The invention relates to a shower control valve assembly which includes a casing mountable in a wall with inlets for hot and cold water. A cartridge is insertable into the casing in one of two orientations so that the hot water inlet of the cartridge can be aligned with either one of the casing inlets, depending on which one is the hot water inlet. The casing has at least one outlet for transporting mixed water to the tub and a diverter passage is connected to the outlet for transporting mixed water to the shower. An insert is positioned in the outlet and has a counterweighted butterfly valve member therein, the valve member being normally in an open position allowing water to flow to the tub. A rod member extends laterally of the insert and is reciprocable so as to contact the upstream wing of the valve member and force it into the stream of water flowing to the tub. The stream forces the valve member to a closed position and then the flowing water is forced to follow the diverter passage to the shower. When the water is turned off, the counterweight forces the valve member to resume its open condition. The rod member is rotatable and cooperates with appropriate means in the insert to effectively throttle water flowing to the shower to act as a volume control therefor.

Date Sep. 30, 1993The timber (2) passes in a direction of movement (3) between successive clamping roller pairs (27, 26), between which a test roller (48) imposes a flexible bending fD on the timber (2). The imposed flexible bending fD is maintained at least approximately constant by controlling a setting drive (70) by means of a computer (83). Any possible natural curvature of the timber (2) is measured by measuring elements (80, 81) and is taken into account. The thickness (d) of the timber is also measured without contact by measuring elements (81, 82). The restoring force is measured by a force measuring device (68) and the position of the test roller (48) transversely to the direction of movement (3) is measured by a distance transducer (77). From this the commuter (83) calculates the local modulus of elasticity in flexure and combines this, for the final evaluation of the timber (2), with information about strength and density of the timber (2) which results from an irradiation of the timber with a fan shaped beam of radiation (75).
