Title: Tangent flow cylinder head
Inventor: SMITH STEPHEN
IPC: F02F1/40
Filed: 1989-10-06
Granted: 1994-03-29
Abstract: TANGENT FLOW CYLINDER HEAD Abstract of the Disclosure An internal combustion engine cylinder head includes a lower water jacket chamber with a plurality of angularly spaced exhaust passages extending therethrough.  Partition webs connect each of the passage walls with the jacket periphery to separate the jacket chamber into alternate inlet and outlet sections through which coolant flows around each exhaust passage from the inlet to the outlet section.  The webs are made tangent to the passage walls on their sides toward their respective outlet sections to avoid forming stagnant pockets for coolant in the outlet sections between the passage defining walls and the boundary wall.  The webs may also extend tangent to internal stud bosses on their sides toward the inlet sections to also minimize pockets therein.

IPC: F17C1/00
Filed: 1991-10-04
Granted: 1994-07-26
Abstract: A thermoplastic  pressure  vessel  consisting  of  a container having an exterior sidewall,  a bottom and an annular top rim.  An annular seal surface encircles the top rim.  An annular collar extends outwardly and downwardly from the sidewall adjacent the top rim.   The downward portion of the collar is spaced from and substantially parallel to the sidewall of the container such that an air cavity is formed between the collar and the sidewall.  The collar has a threaded exterior surface.   A closure is provided having a top with a depending annular skirt.  The skirt has an upper portion of a first diameter with an interior sealing surface and a lower portion of a second diameter larger than the first diameter having a threaded interior surface.  When the closure is positioned on the container the interior sealing surface of the upper portion engages the seal surface on the side of the top rim and the threaded interior surface on the lower portion of the skirt engages the threaded exterior surface on the collar to form a threaded connection thereby maintaining contact between the seal surfaces.  The threaded connection is partially insulated by the air cavity from inward and outward flexing of  the  sidewalls  of  the  container  resulting  from differentials  in  pressure,  and  is  capable  of  limited flexion to maintain contact between the seal surfaces when such flexing occurs.

Abstract: Un système de chauffage de fluide instantané à écoulement traversant (10), conçu pour satisfaire les besoins d'un dispositif de chauffage non limité par une connexion à un réservoir de stockage, et pouvant être réalisé à l'aide d'une structure en plastique (42, 62), comprend un refroidissement lorsqu'il n'est pas en marche, et il se caractérise par une purge ainsi qu'une évacuation et un drainage simplifiés. Le système consiste à utiliser un ou plusieurs compartiments (40, 60) habituellement assemblés dans deux modules de compartiment connectés en série. Chaque compartiment comprend une structure (42, 62) présentant une région intérieure cylindrique creuse. Un orifice d'admission (44) est situé au niveau d'une extrémité de la structure, et un orifice de sortie (46) est situé au niveau de l'autre extrémité de la structure. L'extrémité inférieure de chaque structure est fermée par une base amovible (80), et l'extrémité supérieure de ladite structure est fermée par une plaque supérieure (85) ainsi qu'un élément chauffant (140, 160). Ledit élément chauffant (140, 160) est positionné axialement dans la région intérieure du compartiment. Un système de régulation (200) utilise des comparaisons de températures afin de détecter l'écoulement à travers le système de manière à déterminer si les éléments chauffants (140, 160) doivent être activés afin de maintenir le fluide à une température de veille ou à une température opérationnelle.

Title: Tamper-evident closure cap for containers
Inventor: GUILLOT CHRISTIAN
IPC: B65D41/48
Filed: 1993-03-24
Granted: 1999-06-01
Abstract: The invention relates to a tamper-evident closure cap for a container having a neck and an opening defined in the  neck.  The  closure  cap of  the  invention  comprises  an annular skirt member adapted to be secured to the neck of the container to prevent removal of the  closure  cap  from the container,  and a closure member hingedly connected to the skirt member for pivotal movement between a closed position whereat  the  closure  member  closes  the  opening  of  the container and an open position whereat the closure member provides access to the opening, the closure member having a top planar portion extending in a first plane. A manually graspable tab is fixedly connected to the closure member for moving same from the closed position to the open position.  The closure cap further includes a tamper-indicating member removably connected to the skirt member in overlying relation with  respect  to  the  tab  and  adapted  to  prohibit  initial opening of the closure member prior to removal of the tamper-indicating member.  The tamper-indicating member comprises a manually graspable tongue portion and at least one elongated attachment portion extending between the closure member and the  skirt  member  and  detachably  connected to  the  skirt member,  the tongue portion and the at least one attachment portion being co-planar and extending generally in the first plane.  Thus,  unauthorized removal of the  tamper-indicating member provides  evidence  of tampering or  initial  opening. since,  according  to  the  invention,  the  tamper-indicating member is disposed in overlying relation with respect to the opening means, it is impossible for an unauthorized user to move the closure member from the closed position to the open position without first removing the tamper-indicating member and thus without providing evidence of tampering or initial opening.
