Patent CA-2177437-C (CA)
Inventor: MILLER GEORGE E JR
IPC: E04H7/30
Filed: 1996-05-27
Granted: 2007-09-25
Abstract: A grain bin structure for storing, conditioning, and drying grain having a floor, side walls, and a roof. The side walls are formed with a plurality of horizontal and vertical corrugations formed integrally therein and within a common circumferential plane. The vertical corrugations function as stiffeners and as vertical air conduits to dispense pressurized air about the periphery of the bin. Optionally, conduit tubes may be located within the vertically disposed corrugations to further channel air flow. These conduits are formed with an inner wall substantially flush with the interior of the horizontal corrugation, thereby maintaining a low silhouette while maximizing a cross-sectional area within each conduit to avoid undue restriction of air flow.

Title: Glass break sensor
Inventor: CECIC DENNIS
IPC: G08B13/04
Filed: 1996-08-29
Granted: 2000-07-04
Abstract: The glass break detector uses sampling techniques to a low band and a high band portion of a signal from a transient event to assess whether the bands are random.  In addition, an assessment of the envelope shape of the signal is made to confirm the signal is consistent with a rapid rise followed by a sloped decay typical of transient events.  It has been found that dividing of the signal into high and low bands and analyzing each portion over a short front end portion of a transient event is effective in distinguishing glass break events from other common events.

Abstract: An assembly for collection of a sample of a body fluid from a subject's body of the present invention includes a hollow tube defining an axis with an open end and a closed end. The hollow tube defines a chamber therewithin for receiving a sample of a collected fluid from a subject. The tube has a resilient closure disposed in the open end to close the chamber and to form a seal capable of maintaining a pressure differential between atmospheric pressure and a pressure less than atmospheric pressure within the chamber. The chamber contains an aliquot of an aqueous additive for treating the fluid sample. The chamber also includes a matrix formed from a fibrous material having capillary spaces therein for absorbing the aliquot of the aqueous additive and an aliquot of a water immiscible liquid with a density greater than about 1.07 grams per milliliter to encapsulate the aqueous additive absorbed on the matrix. The tube has a normally closed resilient valve disposed in the chamber to contain the aqueous additive, the liquid and the matrix between the closed tube end and the valve. I he valve is openable by centrifugation when there is a sample in the tube thereby allowing the lower density fractions of the sample and the aqueous additive to collect above the valve and to mix.

Abstract: A method and apparatus for controlling data flow on a network having a server and a non-blocking client node in which the client node may not drop requests received from the server. A process on the non-blocking client node allocates resources on the non-blocking client node and notifies the server of the allocated resources. The server then determines the resources on the nonblocking client node required to fulfill a request by an application on the server and whether sufficient resources are available on the non-blocking client node to fulfill the request by the application. If sufficient resources are available, the server then sends the request to the client node and if sufficient resources do not exist, the server waits until sufficient resources do exist to issue the request to the non-blocking client node.
