摘要:
A wall plate adapter for coupling home network control signals to AC power wiring, where the wall plate adapter includes built-in signaling circuitry. The wall plate adapter includes a plate with a receptacle face with slots that are aligned with slots of an underlying AC receptacle. When prongs of a plug are inserted into the slots of the wall plate adapter, they touch contacts that are located in the slots of the receptacle face. The contacts are, in turn, coupled to the signaling circuitry, which may be located in an enlarged region of the wall plate. The signaling circuitry is only coupled to the AC power when a plug is inserted. The plug may be coupled to a transformer and a network device.

A process for preparing a compound of formula (A), (B) or (C): wherein P is H, CH3 or a hydroxyl protecting group; X is O, a protected ketone, OH, a protected hydroxyl group or H; Y is OH, a protected hydroxyl group or H; W is C(CH3)OH, C(CH3)(C(CH3)3)OH or COCH3; Z is C2-C10 alkyl or C2-C10 arylalkyl; and ′ is a single bond or a double bond, is disclosed. The process is a reductive alkylation in the presence of hydrogen and a reductive alkylation catalyst.

An apparatus and method are provided for a security device for residential and/or commercial use. A first magnetic member has a first magnet with a north and south pole, and a second magnetic member has a second magnet with a south and north pole. Contact between the north pole of the first magnet and south pole of the second magnet, or vice versa, completes an electrical circuit by conducting electricity between the first and second magnets, and a magnetic force between the first and second magnets holds the first and second magnets in contact. The electrical circuit is broken when a force sufficient to overcome the magnetic force is applied to separate the first and second magnets. When contact between the first magnet and second magnet is broken off, such as by opening a door or window, the electrical circuit is broken, and an alarm is triggered.

A system for monitoring the pressure in a pneumatic tire supported on a wheel of a vehicle, the wheel being rotatable about an axis of rotation and defining a plane of rotation that is perpendicular to the axis of rotation. The system includes a housing mounted on the wheel of the vehicle and a sensor in the housing for measuring a pressure condition in the pneumatic tire. The system also includes a transmitter coupled to the sensor for generating a radio frequency output signal conveying the pressure condition measured by the sensor. The transmitter includes an antenna contained in the housing, where this antenna is configured to transmit the output signal according to a radial pattern. The system further includes an orientation mechanism operative to orient the housing during mounting of the housing to the wheel of the vehicle. The orientation mechanism may be further operative to orient the antenna within the housing. The orientation mechanism ensures that, once the housing is mounted to wheel of the vehicle, the output signal is transmitted substantially in the plane of rotation of the wheel of the vehicle.

The present invention relates to valve constructions which allows two different flow rates to pass through said valve, whether by two separate control signals or by one control signal and the second flow rate being attained automatically or inherently after the first flow rate has passed through the valve. The invention also includes a filter material cleaning system and a method of operating a filter material cleaning system which utilizes this valve but which helps to prevent the factors which would cause the re-deposition of the filtered particulate material whether onto the row of filter bags being cleaned, and or an adjacent row to the row being cleaned or two adjacent rows to the row being cleaned.
摘要:
An apparatus for attachment to an overhead crane for removing the bearing assembly from a vertical centrifugal pump system without removing the motor. The apparatus includes a rigid C-shaped frame which is attached by a pulley to an overhead crane and also includes a pivotal attachment on the opposite end of the frame which is removably connected to the bearing assembly. Intermediate and vertically aligned with the ends of the frame is a horizontal displacement control member which is removably connected to the bearing assembly at a point vertically above the pivotal attachment. Horizontal displacement of the horizontal displacement control member will cause a rotating of the bearing assembly about the pivotal attachment allowing clearance and lateral removal of the bearing assembly from the vertical pump system.

A processing device may generate a data encryption key configured to encrypt unique data within a clone of an encrypted data set and associated with a set of transaction identifiers of a transaction based file system. The processing device may further wrap the data encryption key with a wrapping key, create a cloned encrypted data set with the data encryption key, and store the wrapped data encryption key with the cloned encrypted data set indexed by at least one of the set of transaction identifiers.

This invention relates to intermediates useful in the preparation of opiate alkaloids, particularly morphinane compounds. The invention also relates to processes for preparing such intermediates and to processes which utilise such intermediates in the synthesis of morphinane compounds.
摘要:
A tamper detection switch is disclosed primarily for use in an enclosure of a security system component. The enclosure has a base and a cover that may be repositioned relative to the base. One of the cover and the base holds a conductive magnetic element free to translate within a predetermined range generally perpendicular to the respective cover or base. The other of the cover and the base holds at least two ferrous metal contacts of an open tamper circuit in proximity of a conductive magnetic element. In the closed position the conductive magnetic element bridges the ferrous contacts and closes the tamper circuit. Attempts to tamper with the enclosure separate the ferrous contacts from the conductive magnetic element, opening the tamper circuit and signaling a possible attack.
