Patent CA-2264102-A1 (CA)
Title: Calender
Inventor: KUESTERS KARL-HEINZ
IPC: F16C13/00
Filed: 1997-07-03
Abstract: A calender which includes a deflection-controlled roller with a rotating hollow cylinder and a non-rotating cross-head. Hydrostatic supporting elements on the cross-head can be radially displaced towards the inside circumference of the hollow cylinder, and have bearing pockets in their contact surfaces. The position of supporting elements are controlled using a cylinder space with a small cross-section. When there is a problem with the web, the cylinder spaces can all be hydraulically relieved, eliminating the contact pressure and therefore the exertion of force by the supporting elements.

Inventor: STAHLEY ROBERT EDWARD
IPC: B65D83/06
Filed: 1997-10-08
Abstract: A powder dispenser (10) includes a resilient container (12) for storing a powder and a volume of air therein. The powder has properties which enable a portion of the volume of air to fluidize a portion of the powder when the resilient container (12) is sufficiently deformed. The dispenser (10) has a substantially rigid conduit (16) connected to its discharge end. The conduit (16) provides the only fluid communication between the inside of the container and an ambient outside environment. The dispenser also has a resilient flat member (30) connected to the outer end of the conduit (16). The flat member (30) has a slit (32) that is normally closed such that the container (12) is substantially sealed in a fluid-tight manner until the container (12) is sufficiently deformed to generate a pressure in the volume of air. When a pressure differential exists that is greater than a threshold value, the pressure differential causes the slit (32) to open to discharge a portion of the powder mixed with a portion of the volume of air. The dispenser may also have an apertured member (26) in the conduit (16) that has at least one aperture therethrough having a total cross-sectional area smaller than a cross-sectional area of the conduit. The at least one aperture provides increased air velocity and turbulence to improve mixing of powder and air.

Title: High-data-rate supplemental channel for cdma telecommunications system
Inventor: ODENWALDER JOSEPH P
IPC: H04B1/707
Filed: 1997-12-19
Abstract: A novel and improved method for implementing a high-transmission-rate over-the-air interface is described. A transmit system provides an in-phase channel set (90) and a quadrature-phase channel set (92). The in-phase channel set (90) is used to provide a complete set of orthogonal medium rate control and traffic channels. The quadrature-phase channel (92) set is used to provide a high-rate supplemental channel and an extended set of medium rate channels that are orthogonal to each other and the original medium rate channels. The high-rate supplemental channel is generated over a set of medium rate channels using a short channel code. The medium rate channel are generated using a set of long channel codes.

Title: Counterpulsation device using noncompressed air
Inventor: FERGUSON WILLARD D SR
IPC: A61H23/04
Filed: 1998-08-13
Abstract: A counterpulsation device that operates without the use of compressed air or pressurized gas includes at least one inflatable cuff that is adapted to be placed about a selected portion of the patient's body. A  conduit connects the inflatable cuff to an air transfer device so that noncompressed air can be transferred from the air transfer device to the cuff through the conduit to inflate the cuff. The conduit also connects the cuff to the air transfer device so that air can flow through the conduit to deflate the cuff. Another conduit is coupled to the first so that the air in the system can be selectively vented into the atmosphere. A series of valves are placed on the conduit to selectively control whether air is supplied to or withdrawn from the inflatable cuff. The air moving device preferably is a cylinder having a piston that moves through the cylinder to move the air from within the cylinder through the conduit and into or out of the cuff as desired. The piston moves through the cylinder through the use of a linear servo actuator that is controlled by an appropriately programmed electronic controller so that the inflation of the cuff is timed with portions of the patient's EKG signal and peripheral plethysmographic wave.
