Abstract: The manhole head assembly is for mounting a cover onto a manhole frame. This assembly has a lower annular rim member and an upper annular rim member. The lower member has a bottom side sized and shaped to rest on the manhole frame. It also has an opposite top side which has an inner surface portion sized and shaped to receive and support the peripheral bottom portion of the cover, and an outer surface portion. The upper annular rim member has a bottom side sized and shaped to rest onto the outer surface portion of the top side of the lower rim member in order to fully surround the peripheral edge of the cover when the same lays on the inner surface portion of the top side of the lower rim member. The upper annular rim member  also  has  an  opposite  top  side  and  a thickness substantially equal to the one of the peripheral sidewall of the cover. Bolts are used for anchoring to the manhole frame, the upper and lower rim members in operative position to receive and support the cover. Such a manhole head assembly is easy to assemble; it has a simple structure and can be vertically adjusted with one or more intermediate rim members to conform with new surface levels.

Abstract: Dispositif (10) permettant de distribuer une quantité prédéterminée d'une matière coulante à partir de chambres ménagées dans une cartouche (148). Ce dispositif comprend un boîtier, une gâchette accouplée pivotante au boîtier (12), ainsi qu'un piston (18) muni de dents (108) sur sa partie supérieure, qui pénètre dans le boîtier en passant à travers une partie supérieure de la gâchette (46). Un cliquet (110) est fixé à la partie supérieure de la gâchette et est en prise avec les dents du piston. Lorsqu'une force est appliquée à la gâchette, le cliquet est poussé en avant. Lorsque cette dernière est libérée, le cliquet recule, entraînant le piston. Ce dernier recule sur une petite distance jusqu'à ce que la force appliquée par le cliquet soit annulée par le frottement entre le piston et un frein à friction (104, 106) monté sur le boîtier, le cliquet coulissant alors sur la dent postérieure suivante se trouvant sur le piston.

Abstract: A flame support 20 has a plurality of discrete regions 22 through which a fuel/air mixture can pass by means of burner ports 13 which extend through the support to a multiplicity of openings 25 at the flame supporting side 24. The support 20 comprises barriers 21/26 which extend between and separate the discrete regions 22. The barriers serve to prevent the passage of the fuel/air mixture from upstream of the support to the downstream side 24 of the support in a region between the discrete regions. In burners provided with such a flame support, the likelihood of resonant combustion noise occurring has been found to be reduced.

Granted: 2000-12-26
Abstract: L'invention concerne une bande adhésive pour emballages, facile à déchirer. La bande adhésive est constituée d'une portion de corps principale allongée ayant une section transversale sensiblement constante et un axe longitudinal sensiblement central, une épaisseur définie par une surface supérieure et une surface inférieure, une largeur définie par une paire de bords latéraux et une longueur définie par des première et seconde extrémités. La bande porte une couche d'adhésif sur sa surface inférieure. La bande adhésive comporte une série de coupures formées dans la portion de corps principale et disposées suivant sa longueur, pour faciliter le déchirement. La bande adhésive a la propriété de se déchirer facilement au niveau des coupures, en formant de longues déchirures qui, en fin de compte, provoquent la séparation de la bande au moins en deux parties. La portion de corps principale de la bande adhésive résiste bien aux déchirures dans toutes les parties autres que celles des coupures allongées. L'invention concerne également un mécanisme pour réaliser les coupures facilitant le déchirement, comprenant un axe de rotation, deux éléments de guidage de la bande pour recevoir une portion du côté non adhésif de la bande adhésive, une surface de support pour la bande, un élément pour couper la bande monté sur l'axe de rotation pour effectuer un mouvement de rotation et ayant au moins une portion pour couper la bande s'étendant sous la surface de support. La portion pour couper la bande est formée et dimensionnée pour réaliser les coupures facilitant le déchirement dans la bande adhésive, en s'engageant d'une manière intermittente avec la bande adhésive pour y former les coupures facilitant le déchirement, à mesure que la bande adhésive est tirée longitudinalement sur la surface de support.

Title: Method for attaching a short-circuit terminal to a connector and a connector assembly containing a short-circuit terminal
Inventor: MAKINO HIROTAKA
IPC: H01R43/20
Filed: 1997-08-14
Granted: 2003-06-03
Abstract: A holding tool (40) is inserted into a retainer-attaching hole or a holding tool-accommodating space (22) with the holding tool (40) supporting a short-circuit terminal (15) therein.  The short-circuit terminal (15) is inserted into a cavity (14) in a connector housing (10) by pushing a rear end of the terminal (15) through a handling aperture (23) by means of a pushing pin (45).  Since the terminal (15) is inserted into the connector housing (10) from its lower side, a front opening of the cavity (14) can be formed into the smallest size so that a short-circuit-releasing member (31) can enter the opening (20). Extraneous substances hardly enter the cavity (14) in the connector housing (10) through the opening (20).  Also, since the handling aperture (23) may be formed into the smallest size so that the pushing pin (45) can enter the aperture (23), the connector housing (10) becomes a small size.  Thus, the connector housing (10) can be prevented from becoming a large-sized configuration and from entrance of the extraneous substances through the front opening (20) of the cavity (14).

Title: Recyclage de charges minerales issues de residus d'une installation de desencrage de papier
Inventor: YOUNG TRUDY DIANE
IPC: D21C5/02
Filed: 1996-03-14
Granted: 2007-02-27
Abstract: Cette invention concerne un procédé permettant de recycler les pigments minéraux contenus dans les déchets produits par le désencrage de vieux papiers. Les résidus de désencrage sont chauffés dans une atmosphère contenant de l'oxygène à une température suffisante pour oxyder complètement la totalité des hydrocarbures organiques présents. De la chaleur, de l'eau et du dioxyde de carbone sont également générés et peuvent être recueillis pour être réutilisés dans ce procédé. La combustion entraîne une réaction chimique qui transforme les pigments originaux contenus dans les résidus de désencrage en de nouvelles formes minérales stables. La cendre issue de la combustion consiste essentiellement en un mélange de gehlénite (Ca2Al2, SiO7), d'anorthite (CaAl2Si2O8) et de perovskite (CaTiO3). La cendre contenant les phases minérales mélangées est ensuite ajoutée à un réacteur dans lequel du dioxyde de carbone gazeux passe par barbotage à travers une bouillie aqueuse d'hydroxyde de calcium afin d'obtenir du carbonate de calcium précipité (P.C.C.). Etant donné que les phases minérales de la cendre contiennent du calcium en tant qu'élément de leur structure cristalline, le P.C.C. va se précipiter et se développer sur les particules de cendre. Ceci permet d'obtenir un pigment de P.C.C. recyclé contenant un noyau de cendre. Les propriétés du P.C.C. recyclé sont similaires à celles du P.C.C. vierge.
