Title: Electronic reset for solenoid activated control in an electronic lock
Inventor: IRVING WILLIAM F
IPC: G07C9/00
Filed: 1998-04-29
Abstract: The technique for electronically resetting a magnetically sealed solenoid to an unattracted, unactuated position is described for use with solenoids which have either a residual magnetic or a permanent magnet holding force necessary to retain the armature of the solenoid in its actuated position until such time as the armature is either physically displaced by a mechanical force or an electronic signal is applied to the solenoid. This displacement creates a reverse polarity magnetic field, effectively overcoming the magnetic field acting to hold the armature in its actuated position, permitting a small mechanical force to reset the armature. In order to prevent a lock or similar device from being conditioned for opening and possibly left in that condition for a significant period of time while unattended jeopardizing the security of the container and its contents, the actuation of the armature in the reset or release phase may occur a relatively short time following its actuation.

Abstract: A door system for closing a doorway in a mine stopping includes a door hinged adjacent the doorway for swinging relative to the stopping between a closed position and an open position. A keeper is mounted in fixed position relative to the doorway. A latch mechanism is cooperable with the keeper for latching the door in its closed position.

The latch mechanism is constructed and configured so that it operates to move the detent portion along a path defined at least in part by an arc centered on a point spaced away from the door whereby the detent portion is adapted to remain in substantial engagement with the keeper to maintain the door closed in the event the keeper moves relative to the door, as in a mine convergence.
Patent CA-2267596-A1 (CA)
Title: Device and method in a cellular mobile telephone system
Inventor: BODIN STIG ROLAND
IPC: G01S5/14
Filed: 1997-09-23
Abstract: The present invention relates to a method and an apparatus in a cellular mobile telecommunication system, primarily the GSM system, to determine the geographical position of a mobile station. The distance between the mobile station and a radio base station is estimated from the propagation delay. The propagation delay is determined according to the present method where the mobile station sends access bursts to the base station which measures the access delay of the arrived bursts in the same way as an ordinary handover. No confirmation on received access bursts is sent from the base station to the mobile station and therefor the handover attempt is terminated. The connection between the mobile station and the previous base station is re-established. The measured access delay is proportional to the propagation delay and thereby also to the distance to the mobile station. The mobile position can be determined with good accuracy if values from at least three base stations are obtained, although with less accuracy if only two values are obtained. Also an access delay measured by earlier known methods can be used together with measurements achieved with the present method to determine the mobile position.

Title: Method and apparatus of converting heat to useful energy
Inventor: RHODES LAWRENCE B
IPC: F01K25/00
Filed: 1999-07-22
Abstract: A method and apparatus for implementing a thermodynamic cycle. A heated gaseous working stream including a low boiling point component and a higher boiling point component is separated, and the low boiling point component is expanded to transform the energy of the stream into useable form and to provide an expanded relatively rich stream. This expanded rich stream is then split into two streams, one of which is expanded further to obtain further energy, resulting in a spent stream, the other of which is extracted. The lean unexpanded stream and the spent rich stream are then combined in a regenerating subsystem with the extracted stream to reproduce the working stream, which is then efficiently heated in a heater to provide the heated gaseous working stream that is separated.

Abstract: An air conditioning unit is provided which includes an outdoor section, which has a condenser coil mounted therein and an outer protective housing partially enclosing the outdoor section. The housing has a substantially rectangular opening therein in overlying relation with the condenser coil. The opening is defined by at least two spaced parallel coplanar wall sections, each of which has a predetermined width. A flexible protective grille, which is configured to substantially cover the rectangular opening, has two edges thereof which are spaced from one another by a distance substantially equal to the spacing of the wall sections. Each of the edges have integrally formed therewith two or more narrow, rigid, spaced apart extensions, which project perpendicularly therefrom. Each of the narrow extensions has a length less than the predetermined width of the wall sections. Each of the wall sections is provided with conformations, which are formed at locations corresponding to the location of each of the narrow extensions. The conformations are configured to mechanically receive and retain the narrow extensions, which are formed on a first edge of the grille without flexing of the grille. The narrow extensions on the second edge of the grille are thereafter mechanically received and retained with their respective retaining conformations upon flexing of the grille. Following assembly of the extensions on the second edge of the grille, the grille returns to its undeformed condition and is then thereby positively mounted in the opening.
