Patent CA-2074118-A1 (CA)
Title: Metal metering pump system
Inventor: TURNER OGDEN L
IPC: G01F11/00
Filed: 1992-07-17
Abstract: ABSTRACT OF THE DISCLOSURE A  metal  metering  pump  system  for  sequentially dispensing precisely metered  quantities  of metal,  such  as zinc,  aluminum or lead calots  used in the manufacture of battery  cases,  incorporates  a  reciprocating  shaft  of selectively variable stroke, with a piston operating within a cylinder immersed in a reservoir of the molten metal.  The piston has a slide valve mounted at one end,  serving as a check valve pumping of the liquid metal.   Variation in the length of the piston stroke controls the quantity of liquid metal  that  is metered at each stroke.   Withdrawal of  the piston  induces  flow  of  the  molten  metal  into  the  pump. Advancement of the pump piston discharges the metered quantity to a non-return discharge valve.  The discharge valve connects the interior of the pump through the bottom of the tank to a conveyor located therebeneath, onto which the metered quantity of  liquid  metal  is  discharged.    The  discharge  valve  is pressure  sensitive  to open,  and pressure head and gravity biased to close.

Title: Conduit Valve Providing Wide Neutral in a Hydrostatic Transmission
Inventor: HAVENS DALE I
IPC: B60K17/10
Filed: 1993-05-28
Abstract: A valve mechanism for a hydrostatic transmission having a variable displacement pump and a motor in fluid communication with each other via a closed-loop fluid system.  The valve mechanism provides pressure relief and a wide neutral feature within a predetermined range of movement about a zero displacement or neutral position of the pump.  The valve mechanism is variably controlled by and in coordination with the movement of the displacement pump control mechanism from a fully open position through a fully closed position, such that as the pump is shifted into and out of neutral from both a forward and reverse displacement position, the valve mechanism is moved therewith.  The valve mechanism constitutes a ring surrounding the conduit and is responsive to the pump control mechanism so as to move concentrically therewith. The ring valve includes bores selectively communicating with respective bores in the fluid system such that the fluid system is in selective communication with a cavity formed in the housing. The bores provide a metered leak path from the fluid system within 3° of neutral in either the forward or reverse displacement positions upon actuation of the pump control mechanism into the same displacement position so as to reduce the pressure within the fluid system during engagement of the transmission.  Movement beyond 3° completely closes the valve such that full pressure may be developed within the fluid system.

IPC: H05K7/20

Abstract: An enclosure for heat generating electronic components establishes an airflow path for cooling air. Air is forced through the enclosure by powered air movers, one of which is mounted at the air inlet to the enclosure, and the other of which is mounted at the outlet. Preferably only one air mover is used at a time. In the event of failure of the air mover being used, the remaining air mover begins operation. The total cooling airflow passes through both air movers, and thus the air movers may thus be said to be arranged in series with respect to the airflow. Because the air movers are mounted in series with respect to the airflow, the airflow pattern is substantially the same regardless of which air mover is currently operating. Thus, hot spots which may result when one fan in a fan bank fails are avoided. In the preferred embodiment, the enclosure houses a redundant array of independent disks (RAID) of a computer system. In an alternative embodiment, air movers arranged serially with the airflow can be used to provide additional cooling for severe operating conditions. <IMAGE>

Filed: 1993-07-06
Abstract: Selective tributary switching is realized in a bidirectional transmission system by selectively switching, in accordance with the same rules governing the set-up and take down procedures of full line-switching, only that portion of the bandwidth of the particular line which has been provisioned to be line-switched. The remaining bandwidth can be left unprotected or, by for the first time combining line-switched ring functionality with path-switched ring functionality in the same ring transmission system, some remaining bandwidth can be path-switched.  Furthermore, another degree of switching freedom is achieved in a four optical fiber bidirectional ring transmission system by selectively span-switching, but not ring-switching, specific bandwidth on the line. To this end, communications circuit provisioning information is provided in the ring nodes as to whether a particular communications circuit should be line-switched or not and, if not, whether it should be span- switched, path-switched or left unprotected.
Patent CA-2100998-A1 (CA)
Inventor: BRAIN ARCHIBALD I J
IPC: A61M16/06
Filed: 1993-07-21
Abstract: A laryngeal mask airway is described which is fitted with an evacuation or drainage tube which passes through the back of the mask and terminates concentrically within an inflatable-cuff formation at the distal end of the mask.  In the case of a laryngeal mask which relies on an inflatable ring to establish a seal around the laryngeal inlet, the inflatable-cuff formation results from sealed passage of the evacuation tube through the distal region of the inflatable ring, the distal end of which is centrally apertured and re-entrantly folded into sealed junction with the distal end of the tube.  When the mask is inflated, its distal end establishes a cuff, sealing the tube against the upper oesophageal sphincter.  In the presently preferred embodiment, an auxiliary inflatable cuff is carried at the back side of the mask and, when inflated, establishes a cushioned reference between the evacuation tube and the posterior wall of the pharynx, enabling more effective sealing of the mask to the laryngeal inlet and of the drainage cuff to the oesophageal sphincter, in the circumstance of negative pressure applied to the evacuation tube.

Abstract: Abstract A method of forming a nonwoven web having delayed antimicrobial activity, in that the web does not exhibit antimicrobial activity upon its formation but develops such activity within from about three hours to about 30 days thereafter without any post-formation treatment, which method involves the stepsof (1) melting a mixture consisting of a thermoplastic polyolefin, an additive, and a retardant coadditive; (2) forming fibers by extruding the resulting melt through under defined conditions of shear and throughput; (3) drawing the fibers; and (4) collecting the fibers on a moving foraminous surface as a web of entangled fibers. The additive is a defined siloxane quatenriary ammonium salt having a weight average molecular weight of from about 800 to about 2,000 and a polydispersity of up to about 3Ø The additive is present in an amount of from about 0.5 to about 2.0 percent by weight, based on the amount of thermoplastic polyolefin. The retardant coadditive is a high surface area particulate inorganic or organic material which is insoluble in the polymer at both ambient and melt-extrusion temperatures, is present in an amount of from about one-half to about two times the amount on a weight basis of the additive, has a surface area of from about 50 to about 500 m2, and is capable of being at least partially being coated by the additive.

Abstract: L'invention décrit un dispositif de nettoyage servant à appliquer une solution de nettoyage liquide sur la surface d'un disque support d'information tel qu'un disque laser ou compact ou similaire. Le dispositif de nettoyage comprend un boîtier pourvu d'un axe rotatif conçu pour supporter le disque dans un sens généralement horizontal et combiné à un système de circulation pourvu d'un rotor de pompe rotative servant à pulvériser un jet de solution de nettoyage sur la face inférieure du disque à proximité de l'axe. Un moteur de transmission fonctionne par l'intermédiaire d'un circuit de commande, afin d'imprimer une rotation initiale à l'axe et au rotor dans un premier sens, de manière à pulvériser la solution de nettoyage contre le disque en rotation, ladite rotation provoquant l'étalement de ladite solution vers l'extérieur dans un sens radial, ce qui forme une pellicule sur la face inférieure du disque. La solution de nettoyage est rejetée de la circonférence du disque et est récupérée par un déflecteur extérieur profilé qui la renvoit vers le rotor de la pompe. A la fin d'un cycle de nettoyage court, le circuit de commande inverse le sens de rotation de l'axe et du rotor, afin de faire tourner le disque dans un deuxième sens, ou sens opposé, pendant la durée d'un cycle de séchage court, sans lui appliquer de solution de nettoyage.
