Patent CA-2522908-A1 (CA)
Inventor: DICK BRIAN GEORGE
IPC: F24F5/00
Filed: 1992-06-08
Abstract: A reversible vapour compression refrigeration plant serves as an air conditioner for cooling or as a heat pump for heating. A main stream of inlet air is divided into separate main and bypass streams of air and proportion of flow between the two streams is varied in an inverse ratio so that as flow through the bypass duct increases, flow through the main duct decreases and vice versa. When the plant is used for heating, the main stream is heated by a supply heat exchanger acting as a condenser and when the plant is used as an air conditioner, the supply heat exchanger acts as an evaporator. Also, as an additional alternative, as a desired air space temperature is approached, preferably heat rejected by a condenser in the heating mode, or heat gathered by the evaporator in the cooling mode, is gradually reduced by reducing refrigerant flow therethrough by modulating compressor suction. Full fresh air or full re-circulating air modes, or a combination of mixed and re-circulating air can be used. Also, energy is saved in both the heating and cooling modes by locating an exhaust heat exchanger within exhaust flow discharged from the space to be heated or cooled.

Title: Evacuation system
Inventor: GOOD MERRILL R
IPC: B67D7/08
Filed: 2004-04-29
Abstract: An evacuation system including an evacuation member engages a product package and applies pressure thereto, such that a product in the product package moves toward an outlet in the product package for dispensing. A controller monitors the force applied by a driver to the product package, thereby ensuring that the pressure remains below a particular threshold to protect the integrity of the product package. The controller further monitors the evacuation member location, thereby enabling the controller to recognize when the product package is empty. The evacuation system further includes a package carrier including a pinch-off area that moves product out of an unrecoverable portion of the product package. The evacuation member may be utilized as a stand-alone device or with a primary device, wherein the primary device provides signals to the evacuation system and the evacuation system provides product to the primary device.

Title: Method of reconstructing a bituminous-surfaced pavement
Inventor: THOMAS TODD
IPC: G01M99/00
Filed: 2004-11-17
Abstract: A method of reconstructing a bituminous-surfaced pavement is provided. This method includes evaluating the pavement to determine if it is an appropriate candidate for full-depth reclamation; mixing an emulsion with reclaimed asphalt pavement particles from the pavement to form an asphalt emulsion mix;  and testing the asphalt emulsion mix for performance using a cohesion test, a moisture susceptibility test, and a modulus test. In many instances, dirt and/or aggregate form the base layer of the pavement are also included in the asphalt emulsion mix. The invention also includes designing a full-depth reclamation (FDR) layer based on this test data. Once the layer is designed, the bituminous surface of the pavement is pulverized, an emulsion is mixed with the pulverized reclaimed asphalt pavement particles from the bituminous surface and possibly dirt and/or aggregate form beneath the bituminous surface of the pavement, and this mixture is applied to the pavement.

IPC: H04M3/42
Filed: 2004-08-26
Abstract: Conventionally , there is a method where a certification of contents is mailed in order to legally prove that intention of one party is transferred to an opposite party. Namely, one party who desires to retain a legal evidence showing that the one party transferred his intention to the opponent party mails the content certification to prove such a transfer of the intention from the one party to the opponent party. However, this method has a problem in that an emotional trouble may arise between the two parties. The present invention provides a method of proving service for telephone call recording and a system thereof, wherein a calling party inputs a telephone number of a call content proving apparatus and a telephone number of a called party to establish call connection with the call content proving apparatus and the called party, content of a call between the calling party and the called party is automatically recorded in the call content proving apparatus, and a certificate for the recorded call content is issued by the call content proving apparatus, so that the content of the call between the calling party and the called party can be proved by the certificate issued by the call content proving apparatus and can be opened to other parties.
