Patent CA-2242251-A1 (CA)
Inventor: SCHNEIDER KARL-JOSEF
IPC: C21C7/068
Filed: 1998-06-30
Abstract: A method and an apparatus for producing steels with predominantly high Cr content and/or ferro-alloys, wherein the metal charge is melted in a melting crucible, is alloyed, refined and reduced, and wherein process gases are simultaneously supplied through bottom nozzles.  A melting crucible is used with a specific reaction volume of 0.4 to 1.5 m3/t steel and the injection rates of the process gases are controlled in the range of 0.1 to 3.0 N m3/t/min.  The solid charge material is melted by an electric arc and air/nitrogen are injected simultaneously and, after forming a liquid sump, a gas mixture of oxygen and inert gas is injected.  After adding slag-forming constituents and alloying agents, the oxygen throughput is increased and the power of the electric arc is reduced accordingly.  The oxygen throughput is reduced in relation to the inert gas during refining and decarburization takes place as a result of increasing the electric arc with low chromium slag formation.          During the reduction of the melt with suitable reduction agents, primarily chromium is reduced from the slag and silicon is bound by slag-forming constituents.

Title: Heater housing for an electric clothes dryer
Inventor: ST LOUIS ROBERT MAURICE
IPC: D06F58/26
Filed: 1999-05-27
Abstract: An electric clothes dryer has an irregular polygonal shaped rear wall where the apexes in the polygon align readily with the center of the heater housing to define positions where the electrical insulators are mounted to the heater housing rear wall. Raised land pads are formed from the rear wall of the heater housing at these locations and on which the insulators are mounted. The raised land pads further have radial slots that permit airflow from beneath the pad into the heater housing and across the insulator and the heating element. The apexes further provide an increased air gap for increased airflow radially across the electrical insulators. The heater housing has an air gap with the rear end head of the dryer drum which air gap is smaller adjacent the upper portions of the heater housing so as to reduce the chimney effect associated with the air heated in the heater housing.

Patent CA-2278461-A1 (CA)
Inventor: SWALE RICHARD PAUL
IPC: H04M3/42
Filed: 1998-01-02
Abstract: An intelligent network in which the service switching points (SSPs) consult a lookup table for services which require the use of a service control point (SCP), and send respective request messages containing a service type field.      If such a service is one which can be handled by an SCP whose LAN (for the intercommunication of its various data processors) has become partitioned because of, say, a LAN fault, the SSP writes a first value for service type into the field, and if the service is one which must not be handled by a partitioned SCP, the SSP writes a second value. The request messages are sent via service transfer points (STPs). The network includes transmission control means which has first and second states. Any SCP which detects that its LAN has become partitioned commands the transmission control means to enter the second state. In the first state the transmission control means is transparent to all messages regardless of the contents of the service type field, but in the second state it does not pass requests of the second service type. In one embodiment, each STP is integrally constructed with a respective transmission control means. In another embodiment, each SCP includes one or more respective transmission control means disposed at the junction of its signalling servers and the signalling link from the STP.

Abstract: Precis  La poignée de porte (FLEX) est le résultat de plusieurs années de travail en  tant que monteur et installateur de portes exclusivement dans le domaine de l'élevage . Portes et poignées subissant un usage intensif et rude il ne se trouvait sur le marché  aucune poignée de porte calibrée pour cette usage, la corrosion dû à l'humidité élevée de bâtiments destinés à loger un grand nombre d'animaux, la sudation et les gaz  acidulés produit par les excréments ont un impact destructif sur les composantes des poignées de porte ordinaire qui sont conçues pour tes bâtiments résidentiels. Le trafique des chariots de moulé ou autre est une deuxième raison pour laquelle il fallait créer une poignée de porte au profile particulier, car la poignée de porte résidentielle est exposée, ne résiste pas au choc de ces véhicules. La troisième raison est dû  à l'aisance d'utilisation; une poignée qui opère par la rotation est mal aisé quand on a  les bras chargés ou que le chariot est entre nous et la porte. Une poignée tire-pousse sera par ce fait bien plus appréciée.  Et il y a aussi l'aspect installation de cette poignée (FLEX) qui est très simplifiée et requière moins de préparation à son installation tel que trous du loquet et trous de la bavette non requise pour la poignée Flex. Et un prix compétitif pour une poignée de haut e gamme dû à un mécanisme simple et robuste.
