IPC: H02G1/12
Filed: 1991-02-22
Abstract: Un outil permettant de dénuder les fils comporte un corps (10) définissant un orifice dans lequel on peut placer la partie terminale d'un fil à dénuder. Un élement de serrage en U (20), équipé d'une paire de mâchoires de serrage (21, 22) peut coulisser le long de l'orifice, les mâchoires coopérant avec les surfaces à cames (18, 19). Un couteau en forme d'U (33) a une paire de bords de coupe (34) commandés ensemble par coopération entre les butées (35) attenant aux rebords (34) et les mâchoires (21, 22), et entre les mâchoires et les surfaces à cames (18, 19). Un mouvement est imparti au couteau (33) lorsque l'on fait pivoter la poignée (12), et le couteau entraîne l'élément (20) jusqu'à ce que ses mâchoires prennent contact avec un fil. Le mouvement ultérieur du couteau (33) fait en sorte que les griffes (31) de l'élément (20) passent au-dessus de la base (36) du couteau (33). Simultanément, les bords de coupe (34) pénètrent dans le fil ainsi serré et après un mouvement supplémentaire du couteau la couche partiellement coupée est complètement sectionnée et l'isolement est retiré de l'extrémité du fil.

Abstract: An apparatus for identifying equipment, including the maintenance of usage histories for the equipment and recommending whether the equipment is to be used in a prospective application based on prospective application and usage history. A portable encapsulated passive circuit capable of transmitting an identification code is affixed to a piece of equipment. The circuit is activated by a portable reader which receives and decodes the identification code and transmits it to a central computer. The central computer verifies the reader and the existence of the equipment in a database and retrieves the usage history for the equipment. Based on the usage history, the prospective application and guidelines for usage of equipment, the computer determines the advisability of using the equipment in the prospective application and transmits the recommendation back to the portable reader.

Abstract: The present invention relates to a stable hemoglobin based composition having sufficiently low levels of methemoglobin to effectively function as an oxygen carrying solution upon administration to a patient made by the process comprising: a) adding an oxygenated or deoxygenated form of said blood substitute to an oxygen impermeable package, and b) storing said container at from between 5  DEG C to 45  DEG C for sufficient time to permit the autoreduction of methemoglobin. The stable hemoglobin based composition includes hemoglobin, modified hemoglobin and/or encapsulated hemoglobin. To effectively function as an oxygen carrying solution upon administration to a patient, the stable hemolobin based solution cannot have greater than about 50 % of said hemoglobin based solution in the methemoglobin form but, preferably no more than about 15 %. The invention further relates to a method to store a stable oxygen carrying solution according to the above discussed process.

Abstract: Sont décrits un ensemble siège pour véhicule comportant un siège (22), un dossier (23) et des moyens de fixation (25) du siège permettant le mouvement en sens avant et arrière dans le véhicule le long d'une trajectoire arquée concave vers le haut. Cette trajectoire arquée (42) présente un rayon de courbure qui est suffisamment grand pour permettre au siège d'avoir le temps de se déplacer vers l'avant afin de retenir les fesses de la personne en vue de ralentir notablement la vitesse de décélération de la personne assise sur ledit siège (22), et qui est suffisamment petit pour convertir une partie de l'énergie cinétique linéaire des fesses de la personne en énergie cinétique angulaire, maintenant ainsi le contact par frottement des fesses de la personne avec le siège (22) lors d'un arrêt à une vitesse de décélération élevée. Est également décrit un ensemble siège qui comporte un support lombaire inférieur accouplé pour permettre le mouvement en réaction à un mouvement d'inclinaison pelvienne du siège. Le procédé consiste à mettre en oeuvre un siège (22) dont la fixation permet le mouvement, en suivant une trajectoire arquée (42) concave vers le haut, dans le sens avant-arrière dans un véhicule en vue de réduire les blessures d'une personne assise sur le siège lors d'une collision frontale du véhicule avec un objet.

Abstract: A process is disclosed of preparing a photographic emulsion containing tabular silver halide grains exhibiting a reduced degree of total grain dispersity. After forming a population of silver halide grain nuclei containing parallel twin planes, ripening out a portion of the silver halide grain nuclei. The silver halide grain nuclei containing parallel twin planes remaining are then grown to form tabular silver halide grains. The total grain dispersity of the emulsion is reduced by incorporating bromide ion in the dispersing medium prior to forming the silver halide grain nuclei and, at the time parallel twin planes are formed in the silver halide grain nuclei, a polyalkylene oxide block copolymer surfactant containing terminal hydrophilic alkylene oxide block units linked by a lipophilic alkylene oxide block unit accounting for at least 4 percent of the molecular weight of the copolymer.
