| 20110266282 | WEATHER-PROOF SEALING FOR ENCLOSURE - A method of sealing a first part to a second part of an enclosure. The first part is a metal extrusion having a channel-shaped cross-section and the second part is a light-transmissive plate, together forming the enclosure. An electrical light source located in the enclosure shines light through the light-transmissive plate. The sealing method includes placing an elongate seal member into a groove of a first part of the enclosure, extending along the groove, and inserting an edge of a second part of the enclosure into the groove of the first part. | 11-03-2011 |
| 20100051844 | ELECTROMAGNETIC VALVE - In an electromagnetic valve, a stator assembly includes an electrically energizable coil and a thin-walled core which receives and reciprocally supports an armature. The thin-walled core has a closed end and an open end, the open end being in fluid communication with a fluid flow passage within a valve member. The valve member reciprocates with the armature to control flow rate in the flow passage. A flange integral with the thin-walled core extends about the open end. A washer receives the thin-walled core and abuts the flange. The flange and the washer are received in a recess in the valve body and are permanently and sealingly fixed therein by a swaged joint in the valve body. | 03-04-2010 |
| 20090167506 | METHOD OF CONTROLLING NETWORKED KITCHEN APPLIANCES - A method of controlling the operation of a wireless network of intelligent kitchen appliances for performing a recipe allows a user to provide authentication of commands received over the network by manual actuation of a touch-sensitive switch mounted to the appliance, and which initiates operation according to the command. A hand-held remote controller has a display for showing instructions to the user. The controller transmits associated appliance commands to the appliance, where they are stored, and the appliance then performs each appliance command conditionally, upon a change of state of the switch. | 07-02-2009 |
| 20090160639 | KEYLESS ALERT SYSTEM AND METHOD FOR AUTOMOBILES - A keyless alert system for use in a car incorporating a keyless control system including a master controller and a remote controller co-operable via an RF communication link. The keyless alert system comprises a master alert unit in the master controller, a remote alert unit in the remote controller, and an alert signal generator in each of the alert units for providing an alert signal while the car engine is running and when the communication link fails by reason of the remote alert unit being separated from the master alert unit beyond a certain distance. | 06-25-2009 |
| 20090026058 | TRIGGER MECHANISM - A trigger mechanism for an electric power tool, comprises a spring-loaded trigger movable between an foremost position and an rearmost position, an adjuster for adjusting the rearmost position, an electrical switch arranged for closing by the trigger while the trigger is in an intermediate position, and a variable resistor arranged for operation by the trigger while the trigger is in an intermediate position to provide a resistance having a value dependent upon the position of the trigger. A locking device is included for locking the trigger near the rearmost position, and which is movable in opposite directions and arranged to lock the trigger near the rearmost position when the locking device is moved in either one of opposite directions. | 01-29-2009 |
| 20080264769 | ELECTRICAL SWITCH - An electrical switch has two fixed contacts and a moving contact, a spring urging the moving contact towards contacting the fixed contacts, and an actuating mechanism for moving the moving contact away from the fixed contacts against urging by the spring and, alternatively, allowing the moving contact to contact the fixed contacts under the action of the spring. The actuating mechanism has an engaging member for engaging and retaining the moving contact and includes a spring acting on the engaging member for separating the moving contact from the fixed contacts through an instant spring-release action. One of the engaging member and the contacts is configured such that the moving contact will be engaged and moved by the engaging member out of contact with one of the fixed contacts earlier than with the other fixed contact. | 10-30-2008 |
