Title: Method for continuously making kettle style potato chips
Inventor: SAMUELS ROSS DOUGLAS
IPC: A23L19/12
Filed: 2005-07-12
Abstract: A continuous cooking process is disclosed that mimics the U-shaped temperature-time profile produced by a batch kettle fried potato chip operation. Potato slices are placed into hot oil in a flume portion of a continuous fryer. The potato slices exit the flume into an upstream portion of the fryer. Cooling oil is injected to the upstream portion of the continuous fryer to continuously achieve the trough portion of the U-shaped temperature-time profile. The potato slices are then further fried in the downstream portion of the fryer in a region having an increased hot oil temperature. The increased hot oil temperature occurs by injecting hot oil into the downstream portion.  The temperature of injected hot oil can be controlled by the exit moisture content of the potato slices.

Abstract: Estimation of channel characteristics and interference level in a time-varying multi-carrier multi-user systems is carried out concurrently. To perform the estimation, a multitude of data symbols and dedicated pilot symbols are transmitted over the channel. Next, an initial estimate value is selected for the interference level. The initial estimate value for the interference level is used together with the received pilot symbols to provide a first estimate of the channel. The first estimate of the channel is used to determine a new updated value for the interference level, which in turn, is used to update the value of the first estimate of the channel iteratively. The iterations continue until the iteratively updated values of the interference level and channel satisfy predefined limits. The data symbols and the final updated value of the channel are subsequently used to proviEstimation of channel characteristics and interference level in a time-varying multi-carrier multi-user systems is carried out concurrently.

Abstract: An astrocyte-specific drug carrier containing a retinoid derivative and/or a vitamin A analog as a constituent; a drug delivery method with the use of the same; a drug containing the same; and a therapeutic method with the use of the drug. By binding a drug carrier to a retinoid derivative such as vitamin A or a vitamin A analog or encapsulating the same in the drug carrier, a drug for therapeutic use can be delivered specifically to astrocytes. As a result, an astrocyte-related disease can be efficiently and effectively inhibited or prevented while minimizing side effects. As the drug inhibiting the activity or growth of astrocytes, for example, a siRNA against HSP47 which is a collagen-specific molecule chaperone may be encapsulated in the drug carrier.  Thus, the secretion of type I to type IV collagens can be inhibited at the same time and, in its turn, fibrosis can be effectively inhibited.

Patent CA-2610650-A1 (CA)
Inventor: NISSELS ROBERT
IPC: F16K21/02
Filed: 1998-04-21
Abstract: A device for limiting the flow of a fluid from a first region of a patient's body to a second region includes a primary passage for directing fluid from an inlet of the device to an outlet in response to the fluid flow rate being less than a predetermined level and a secondary passage for directing fluid from the inlet to the outlet in response to the flow rate being greater than or equal to the predetermined level. The secondary passage can be characterized as a tortuous flow path and presents a higher resistance to fluid flow than the primary passage. A detector is operative to close the primary passage in response to the flow rate reaching the predetermined level in order to force the fluid to pass through the secondary passage. With this arrangement, when the fluid flow rate reaches a level characteristic of overdrainage, the fluid is forced through the secondary passage in order to effectively reduce the fluid flow rate and prevent overdrainage. As soon as the flow rate decreases below the predetermined level, the primary passage opens itself automatically.
