Filed: 1996-12-27
Abstract: A transversely-mounted grass cutter mower combination with a vehicle is provided which is adapted to be activated to move laterally to the right or to the left with respect to its mounting to the vehicle and/or to move vertically up or down with respect to its mounting to the vehicle. The vehicle is a motor-driven vehicle having front wheels and rear wheels and a longitudinally-extending frame bed therebetween. A transversely-mounted powered grass-cutting mower, having a mower housing and powered grass cutting blades, is mounted to the frame bed by means of a suspended mounting system. The suspended mounting system includes both vertical guidance structure and horizontal guidance structure, and also rigid linkage structure secured between the longitudinally-extending frame bed and the mower housing. A first powered operator which is connected to the rigid linkage structure, is provided for moving the mower housing within the constraints provided by the vertical guidance structure, through a finite number of vertical locations between an upper limit and a lower limit.      A second powered operator is provided for moving the mower housing, within the constraints provided by the horizontal guidance structure, through a finite number of lateral locations between a left lateral limit and a right lateral limit.

Title: Methode et trousse pour surveiller les cycles de reproduction des mammiferes
Inventor: KLEMM WILLIAM ROBERT
IPC: A61B10/00
Filed: 1995-08-17
Abstract: On décrit un procédé pour suivre le cycle ovarien chez des mammifères en mesurant les variations de la quantité d'un ou de plusieurs composés volatils à poids moléculaire bas et en l'occurrence, inférieur à 50 g par mole, présents dans un échantillon provenant du mammifère. Comme échantillon, on peut utiliser les fluides extracellulaires, l'air expiré et l'air de cavités du corps, que l'on recueille sur la femelle plusieurs fois durant le cycle ovarien. On mesure la quantité d'un composé volatil à poids moléculaire bas dans chaque échantillon. Dans la forme d'exécution préférée, le composé volatil à poids moléculaire bas mesuré est l'acétaldéhyde. On enregistre les variations de la quantité du composé à poids moléculaire bas dans chaque échantillon, pour déterminer à quel stade du cycle ovarien se trouve le mammifère, et en particulier pour prédire le moment de l'ovulation.

Patent CA-2198401-A1 (CA)
Inventor: NEACSU VIOREL IOAN
IPC: A63F9/00
Filed: 1997-02-25
Abstract: The invention is a fun game which asks the player to find the solution or the solutions of building a vertical "tower", using balls of different diameters, supported in the structure of the tower by rings positioned on the same vertical axle at different heights. The solution of the game means filling up the whole imaginary cylinder made from rings of the game, the base of the tower and the top-ring with the balls of the game, through the successive laying of the rings and balls (in the inner space of the rings). The difficulty to find the solution, building the tower from the game balls until it passes the top-ring, consists in the big number of ways which appear in the construction because of the number of balls in sets of different diameters and the number of the sets of the tower's legs of different heights. The number of possible combinations, results from the number of different diameters of the balls and the number of different heights of the legs on each level of the tower, it can be increased or decreased from design and output process to change the difficulty of the game. Any of the ways of fabrication of the game will have a fixed number of sets of different legs and a fixed number of legs of the same height in each set, a fix number of rings with the same inner diameter, a fixed number of sets of different balls and a fixed number of balls of the same diameter in each set. With this data and with the specification that the supporting rings have the same inner diameter, equal to the diameter of the tower's base, the player must build the game in such way that every added ball is supported at its base from the tower's base or upon other balls and held in by a ring. Any wrong way of building it is if the balls on any level fall through the middle of the rings. Even if the first couple of levels are stable that does not mean that the whole tower can be built. The limited number of balls with the same diameter makes the game harder to build. In searching of the solution or solutions to the game the player has the possibility: ~ to appreciate and to develop his or her capacity of analysis of the existing variables and the solutions of a given problem;     ~ to improve his or her patience and to measure his or her perseverance in the searching of a problem's solution or solutions, ~ to practice his or her memory's power in the process of building the game, by using the previous experiences; ~ to use the free time in a funny way, using a small, compact and nice game.

Abstract: A cable gland for use with cables (1) having armour (3) of widely differing thickness comprises a body (5) and a gland nut (7) threaded to the body (5) which together enclose an armour grip (9) comprising an armour cone (10) having a male frustoconical surface co-operating with a female frustoconical surface on an armour ring (11). The frustoconical surfaces have substantially equal semiangles in the range 12-20~ and the armour ring (11) and the armour cone (10) are urged together by a mechanism independent of and contained within the gland nut (7). The larger-than-normal semiangle allows the whole range of armour thicknesses to be accommodated by the same gripping components without requiring undue length, and the separated mechanism overcomes side effect that the cone grip is not self-locking. Preferred mechanisms also improve perfomance in deluge tests.

On obtient au moins une mesure en fonction du temps d'un échantillon inconnu et on mesure la propriété respective dudit échantillon sur un certain laps de temps pour en déduire une projection de mesure en fonction du temps (Fig. 3-6). Un ensemble de plusieurs variables de prévision est défini. Celles-ci définissent de manière suffisante les données de la projection des mesures en fonction du temps (Fig. 13). On déduit alors un modèle qui représente la relation entre le déséquilibre congénital ou acquis ou la condition thérapeutique, et l'ensemble des variables deprévision. Ensuite, le modèle est utilisé pour prévoir l'existence, dans l'échantillon inconnu, du déséquilibre congénital ou acquis ou de la condition thérapeutique.
