Patent CA-2223744-C (CA)
Inventor: SWISHER DAVID R
IPC: A61M1/00
Filed: 1996-06-07
Granted: 2003-10-07
Abstract: The present invention provides for an improved airflow sensitive float valve (38) interposed between the collection chamber (15) and one arm of the water seal chamber (16) for allowing the patient to draw as much vacuum pressure as is required during deep inspiration. The float valve also functions to provide for an automatic controlled release of excess negtive pressure in the collection chamber during either continuous auto-transfusion or when there is a low airflow rate condition present. By tailoring a specific amount of water to a given size chamber, the water column inside the water seal chamber is allowed to momentarily engage the floating mechanism before the water seal chamber is emptied of water, and a column of air is subsequently forced through the water column towards the momentarily sealed valve.

Granted: 2003-08-19
Abstract: A sealing device for a gas turbine stator blade, in which a sealing pressure of an inner shroud is raised to enhance a sealing effect. An outer shroud 32 is mounted through heat insulating rings 32a and 32b on a blade ring 50, and this blade ring 50 has air holes 1 and 51, of which the air hole 1 communicates with a space 53 whereas the air hole 51 communicates with a seal tube 2. This seal tube 2 is inserted at its leading end portion 3 into the air hole 51, and a spring 6 is arranged between a projection 4 of the tube 2 and a retaining portion 5 of the air hole 51 to fix the seal tube 2 removably. Cooling air 54 flows on one side from the air hole 1 into the space 53 to cool the shrouds and the inside of a stator blade 31 until it is released from the trailing edge, and on the other hand into a cavity 36 so that the inside of the cavity 36 is kept at a high pressure without receiving a pressure loss because the tube 2 is independent of the space 53.      The high pressure air from the cavity 36 flows out from seal portions 40a and 40b, as indicated by arrows S1 and S2, to prevent the inflow of the hot gas from a combustion gas passage.

Title: Method and apparatus for improving performance of a packet communications system
Inventor: TURINA DALIBOR
IPC: H04L12/56
Filed: 1997-11-27
Granted: 2007-06-05
Abstract: A communications system (10) is provided that uses a multiple access packet reservation type of protocol. The physical channels required for the packet transfers are specially allocated to one mobile station (16) (referred to as a "VIP MS"). The VIP MS (16) has the exclusive priority to use these allocated physical channels for packet data as needed. Consequently, the VIP MS (16) always has the negotiated bandwidth available for the packet transfers. Furthermore, since the VIP MS (16) is given the highest exclusive priority to access these physical channels ("VIP priority"), by allocating a reserved random access channel dedicated to the VIP MS (e.g., on one allocated uplink channel), the variable random access delays experienced by prior systems no longer exist. Since the VIP MS (16) is always scheduled first for transmissions on the downlink, and reserved access is provided for the VIP MS (16) on the uplink, only a constant delay period for the uplink and downlink is involved. In other words, the VIP MS  (16) is guaranteed both a bandwidth for the packet transfers and a constant uplink and downlink delay.
