Abstract: Machine pour la fabrication de tubes en plastique comprenant plusieurs chariots distincts pour le transport de blocs de moulage sur un parcours continu. La première et la deuxième paires de roues sur les côtés opposés de chaque chariot circulent sur les première et deuxième pistes, respectivement, dans une section de moulage du parcours. Une roue décalée est disposée entre les roues de chaque paire et circule sur les pistes de guidage associées et faisant face aux première et deuxième pistes opposées, respectivement, dans la section de moulage. Chaque bloc de moulage comprend une pluralité de blocs secondaires assujettis en aboutement, chaque bloc secondaire ayant une face arquée et ondulée comprenant au plus une ondulation. Des canalisations de vide aux surfaces d'extrémité des blocs secondaires raccordent la face du bloc à un orifice de vide. Des canalisations d'eau de refroidissement aux surfaces d'extrémité des blocs secondaires sont connectées à des orifices d'admission et de sortie d'eau pour assurer une circulation sélective de l'eau de refroidissement dans les blocs. Les orifices des blocs de moulage communiquent avec des canalisations respectives de vide, d'alimentation en eau et d'évacuation d'eau dans un bac d'alimentation longitudinal, le long duquel les blocs de moulage se déplacent dans la section de moulage. Une transmission de train de moules entraîne un nombre sélectionné de chariots au début du tunnel de moulage afin d'entraîner en continu les chariots le long du tunnel de moulage. Un dispositif de transfert suit le parcours continu jusqu'à une zone de transfert et à distance du parcours le long d'une partie significative du tunnel de moulage, et comprend une première et une deuxième sections d'entraînement de chariot à des points sensiblement opposés le long de la transmission, de sorte qu'un chariot se trouvant à la fin du tunnel de moulage est entraîné par une section de transfert alors que l autre section de transfert entraîne un chariot à l'entrée du tunnel de moulage. Le dispositif de transfert accélère lorsqu'une des sections d'entraînement de chariot arrive dans la zone de transfert espacée du parcours continu afin de libérer un chariot au début du tunnel de moulage et il ralentit à la vitesse du train de moulage lorsqu'un chariot entraîné arrive au début du tunnel de moulage.

Title: Malfunction power switch and feedback led for suspend systems
Inventor: CRUMP DWAYNE THOMAS
IPC: G06F1/32
Filed: 1995-08-18
Granted: 2000-02-29
Abstract: A computer system having four states of power management: a normal operating state, a standby state, a suspend state, and an off state. A control unit controls transitions between the various states.  The standby state is characterized by devices, such as a video controller and a hard drive, being placed into a low-power mode transparent to the operating system and the applications executing on the computer system.   The suspend state is characterized by executing code being interrupted and the state of the computer system being saved to a file on the hard drive in such a manner that system power may be removed after the state of the computer system is saved to the hard drive.  Later, after system power is restored, the state of the computer system is resumed by reading from the hard drive and loading it in such a manner that the operating system and application programs are not adversely affected.   The normal operating state and the off state correspond to the typical on and off states of more conventional computer systems.  A single switch causes transitions between the various states.  A visual feedback device, such as an LED is used to indicate the state of the computer system.   While no power management driver is active,  the control unit delays  state  transitions until a suitable power management driver is active.

Abstract: An electric lamp with an enclosed lamp capsule has reduced production manufacturing losses when manufactured with a split eyelet used to duct a lead through the lamp housing. The elongated tube portion of the eyelet has either thinned wall sections or splits formed along the tube axis. When the rivet is set, the tube wall distorts or gives way along the weakened axially lines. The housing glass is then not fractured during riveting, and after riveting the thermal expansion and contraction of the glass with respect to the rivet results in decreased pressure on the glass. The lamp with a split eyelet yields a higher percentage of lamps surviving the manufacturing process, and having fewer cracks or other rivet induced defects in final products.
