Title: Contact arm with internal in-line spring
Inventor: NAVARRE LAWRENCE G
IPC: H01H77/10
Filed: 1997-12-17
Abstract: A circuit breaker contact arm (56) contains a straight elongate through-slot (112) that runs generally lengthwise of the contact arm and is closed at both lengthwise ends. Adjacent each slot, a respective side wall (106, 108) of a cross bar (58) contains a bent slot (114) having a knee (116). A respective cylindrical blow-open pin (118) passes through all three of these slots. A small helical coiled spring (120) occupies the contact arm through-slot and is compressed between the blow-open pin and the end of the contact arm slot that is proximate a cross bar/contact arm hinge pin (110). The spring is laterally confined by the adjacent side walls of the cross bar so as to remain in the contact arm slot about which the contact arm swings. The spring acts between the blow-open pin and the contact arm to bias the blow-open pin in a direction away from the cross bar/contact arm hinge axis. When the blow-open pin is below the knees of the bent slots and the contact arm is closed, completing an interruptable circuit through the circuit breaker, the spring exerts force beneficial to good contact of the contact arm contact (54) with a fixed contact (52). By disposing the spring in the contact arm slot, space is used more efficiently.

Title: Apparatus for automatically sealing an articulated chute
Inventor: JAMIESON JOHN W
IPC: B28C5/42
Filed: 1997-12-23
Abstract: A mechanical device for automatically positioning a closure plate for sealing the opening created by the folding of adjacent segments of an articulated chute to thereby prevent undesired discharge or leakage from the chute is provided. The device, which is particularly useful on cement trucks, includes a closure plate rotatably connected to one segment of the chute and disposed to articulate upon an adjacent segment of the chute so that the closure plate seals the opening when the chute is in a folded configuration and, when the segments are unfolded to deliver a charge, rotates to a position clear of the discharge path. The device also includes means for sealably biasing the closure plate toward the opening when the segments are folded and for biasing the closure plate away from the discharge path when the segments are in an unfolded position.

Title: Process for producing mixed refrigerants
Inventor: HAGA TOSHIO
IPC: C09K5/04
Filed: 1998-01-14
Abstract: A process for producing mixed refrigerants comprises selecting the order of introduction of refrigerant components (groups) so that the liquid density of the refrigerant component (group) to be introduced afterwards is lower at the introduction temperature than the density of the liquid phase of the refrigerant component (group) already introduced into the vessel, or for specific 3-component systems, introducing the first 2 components in descending order of density and selecting the vapor pressure of the final component so as to be higher than the vapor pressure of liquid phase of the component group already introduced into the vessel, with the refrigerant component to be introduced afterwards being introduced into the liquid phase of the already introduced refrigerant component (group). It is thus possible to rapidly and efficiently produce mixed refrigerants with uniform compositions by a simple admixture of different types of refrigerant components in a tank or steel cylinder.
Patent CA-2228899-A1 (CA)
Inventor: ROZANSKI WALTER JOSEPH JR
IPC: H04B15/00
Filed: 1997-03-10
Abstract: A wireless communication system (200) estimates (303) the location of a mobile station (215) when a degradation in the mobile station's communication occurs due to interference, and stores (305) the location estimate in a database. The database is used to determine the potential for the mobile station (215) within the wireless communication system to receive interference based on its estimated location or its proximity to the known interference location. When the mobile station (215) is within a predetermined distance of the known interference location, the likelihood for the mobile station (215) to experience a degradation in call quality, duration, etc. increases. To migitate the degradation due to interference, an alternate carrier (104) is found and if available, the mobile station's communication is handed off to the alternate carrier (104). Attenuation can also be added in the front-end of the mobile station (215) to mitigate the degradation due to interference.

Inventor: SCOTT IAN RICHARD
IPC: G01V1/28
Filed: 1996-08-12
Abstract: A technique is provided for controlling the quality of processed seismic data without requiring subjective intervention. Seismic data, for instance acquired by land or marine techniques, are supplied as input (1) and a portion for testing is selected (2). First and second combinations of seismic data processing steps are selected (3 and 6). The selected data portion is processed (4 and 7) using these combinations and the thus-processed portions are analyzed to calculate the attributes thereof (5 and 8). These measures are compared (9) and the combination of processing steps giving the better attributes is then used to process the input seismic data (10 or 11).
