Patent CA-2229106-C (CA)
Inventor: KAIM JOHN W

Abstract: A fifth wheel for trucks is disclosed. Such fifth wheels usually are mounted on truck tractors and receive kingpins that are mounted on truck trailers. An operating rod is provided to manually disengage the kingpin locking mechanism. In one embodiment the fifth wheel plate is mounted on bases with trunnion pins. The bases are secured to the truck tractor. Retaining pins are received in flanges and serve to block axial movement of the trunnion pins. The retaining pins are disposed parallel to the top surface of the plate and are perpendicular to the axes of the trunnion pins. The retaining pins and flanges may be spaced far enough below the fifth wheel support surface so that a misfed kingpin cannot contact them. Alternatively, or in addition, the retaining pins may be under a protector that extends over the length of the retaining pin to prevent a misfed kingpin from striking the retaining pins. In another embodiment the protector is sized and shaped to prevent a misfed kingpin from striking an extended operating rod of the fifth wheel assembly. The protector may be a convex shaped deflector that shifts the path of the misfed kingpin away from the operating arm, or may be shaped to catch the misfed kingpin. The same shape protector can serve both purposes of protecting the retaining pins and the operating arm. The outer edge of each protector is below the top surface of the fifth wheel plate.

Inventor: SEBASTIANI ENRICO
IPC: F23C5/00
Filed: 1996-10-16
Granted: 2006-08-29
Abstract: The invention relates to an appliance for heating fluids which includes a combustion chamber (20) in which the head (21c) of the burner with flame openings (39) is juxtaposed with a wall (21a, 21b) which separates the chamber from the lower portion of the appliance; in the event of flammable substances bieng present in the environment surrounding the appliance, these can enter the combustion chamber only through the flame openings (39) and similar slots (50) formed in the wall (21a, 21b). This enables the burner flames and/or the ignition element (25) to ignite these substances as soon as they enter the chamber (20), the flames being detached from said wall, thus preventing the formation of unwanted explosive or flammable mixtures in the chamber (20) and any flash back, thereby contributing to the safety of the appliance.

Granted: 2002-07-09
Abstract: (SEE FIGURE I) A call servicing system allows service agents to service calls from customers (1200). The system includes local customer switches (1220), local agent switches (1320), and a customer database connected to a network call center. The local customer switches direct calls to and from the customers and the local agent switches direct calls to and from the service agents (1300). The customer database (1140, 1150) stores information regarding the customers sending the calls. The network call center receives a call from a first one of the customers, queries the customer database to retrieve customer information corresponding to the first customer, and concurrently routes the customer call and the corresponding customer information to one of the service agents.

Abstract: Polymer mixtures are disclosed which comprise at least one homogeneously branched ethylene polymer (A) and at least one ethylene polymer (B) having a crystallinity which is at least 7 percent greater than the crystallinity of polymer (A) with certain provisos. A process for making a molded article using the disclosed polymer mixtures is disclose d as well as films, film layers, coatings and molded articles formed from those mixtures. These mixtures have several advantages over polymer compositions of the prior art, including improved properties at elevated temperatures such as improved softening point under load, improved hardness, improved toughness, improved 100 percent modulus of elasticity, improved compression set, improved ability to prevent oil bleed out at lower temperatures when the mixture contains oil and reduced injection molding cycle time. The mixtures retain their performance advantages even when substantial amounts of additives such as oil and filler are incorporated into the mixture. The mixtures may also be cross-linked after they are formed into the shape of an article to form vulcanized elastomeric products. The polymer mixtures have utility in a variety of applications.

Abstract: Apparatus and method are provided for protecting a reciprocating polish rod from suffering circumferential scoring when it is rotated by a rod-rotator while misaligned and in contact with the carrier bar of a pump jack. A  cylindrical sleeve is inserted through the bore of the carrier bar and any additional stacked components supported thereon. An upset at the top of the sleeve retains it within the bore of the carrier bar and any stacked components. The bottom end of the sleeve extends substantially to the bottom of the carrier bar. The polish rod is installed through the bore in the sleeve and can slide and rotate therein. The polish rod is suspended from the carrier structure with a rod clamp. The sleeve guides the polish rod through the carrier structure without permitting accidental contact of the polish rod and the carrier structure and thereby prevents circumferential scoring of the polish rod when the rod is rotated by the rod-rotator.

Abstract: L'invention concerne un clapet (10) pouvant servir de clapet de non-retour ou de clapet auto-obturateur pénétrable, hémostatique, permettant de fermer hermétiquement un instrument (12) d'insertion de cathéter. Ce clapet comprend un élément (26) d'obturation présentant une résistance élevées à la déchirure et aux fuites, mais supportant néanmoins la pénétration répétée de dispositifs de diamètres très variables. Cet élément (26) d'obturation est en forme de disque et est formé d'un élastomètre styrénique thermoplastique tel qu'un copolymère séquencé styrène-éthylène/butylène-styrène, présentant une faible dureté au rebondissement (ne dépassant pas 30 Shore A environ). L'élément (26) d'obturation, de préférence entouré d'un corps (40) de clapet, est comprimé entre un siège (48) de clapet disposé dans le corps (40) de clapet et un capuchon (56) assemblé au corps (40) de clapet. L'élément (26) d'obturation comprend au moins une perforation (34) qui est fermée par la compression ainsi réalisée. Sous l'effet de cette compression, l'élément (26) d'obturation présente en outre une surface (30) amont ou proximale concave, ce qui le rend très résistant à l'inversion durant les retraits et manipulations répétés des dispositifs d'intervention passant à travers le clapet (10). Ce clapet présente l'avantage particulier de fermer hermétiquement d'insertion (12) avec un haut degré d'efficacité lorsque l'élément (26) d'obturation n'est traversé par aucun dispositif d'intervention, et d'offrir une résistance élevée à la déchirure lorsqu'il est pénétré par des dispositifs de gros diamètre. Le clapet (10) permet en outre de passer aisément des dispositifs sans interférer avec la perception tactile ("sensation") transmise par ces derniers.

Abstract: L'invention porte sur des agents antifongiques à base de dolastatine 10 et sur leurs quatre modifications structurales (appelées ici "peptides"), ainsi que sur des procédés de traitement d'un hôte atteint d'une infection induite par des champignons. Dans des dosages à macrodilution de bouillons de culture, ces peptides se sont avérés avoir une activité fongicide pour les souches ATCC et les isolats cliniques de Cryptococcus neoformans. La spécificité de C. neoformans a été également mise en évidence dans les dosages de diffusion sur disque en phase solide, et l'activité fongicide a été confirmée dans des expérimentations cinétiques d'élimination. Les concentrations fongicides minimales et inhibitrices minimales de la macrodilution du bouillon de culture pour la modification la plus puissante sont comprises, respectivement, entre 0,0975-1,56  mu g/ml et 0,0975-6,24  mu g/ml.
