Granted: 2005-05-10
Abstract: A pavement cutting machine (30) having a rotary cutting wheel (34) which is controlled by a clutch (32) on either the drive shaft (92) of the engine or a driven shaft (84) of the cutting wheel (34) with activation by a deadman's switch (36). The machine (30) also includes a stand (40) that enables the entire machine (30) to be tipped forwardly about its support wheels (44) to expose the cutting wheel (34) so it can be serviced. The clutch (32) preferably is an electromagnetic clutch mounted to the engine drive shaft (92) that is selectively energized by a deadman's switch (36) on a handle (46) of the machine (30) that is constructed and arranged to close upon an operator (48) gripping handle grips (120) of the handle (46). When energized or engaged, a pulley (86) of the clutch (32) rotates in unison with the drive shaft (92). When the handle grips (120) are released, the clutch (32) is deenergized or disengaged, decoupling the cutting wheel (34) from the engine (90).

Abstract: (57) Abstract A basket gate (18) mechanism, typically for use in the cargo holds (12), of bulk carriers (10), includes two opposed gate segments (50, 51) which shut along a central line. Each gate segment (50, 51) is supported at its ends by pairs of different length arms (57, 58, 59, 60), so that when the gate (18) is opened, the segments (50, 51) slope downwardly. The pairs of arms (57, 58, 59, 60) are interconnected by a small and compact direction reversing lever mechanism (61, 62 63, 64) that ensures coordination of the movement of the segments (50, 51). The arms (57, 58, 59, 60) and the supporting framework (52) are protected by a hog back (53). The gate (18) is opened and closed by an actuating means (65), typically a double acting hydraulic cylinder, located between the gate segments (50, 51 ) at their midpoints, and directly acting on said said gate segments.

Abstract: A leveling or elevational positional adjustment system comprises a leg frame member, a leg extension member, and a leg extension stop member. The leg frame member comprises an external corner component having a substantially arcuate configuration, and an internal cross-plate component disposed across the interior of the corner component. The leg extension member has an arcuate cross-sectional configuration essentially matching that of the external corner component of the leg frame member so as to be disposed in surface-to-surface contact with the external corner component of the leg frame member when the leg extension is inserted into the leg frame member, and the leg extension stop member has an external arcuate cross-sectional configuration also substantially matching that of the leg extension member. An actuator screw is mounted upon the cross-plate component of the frame member and is engaged with the leg extension stop member so as to effectively force the leg extension stop member into surface-to-surface contact with the leg extension member such that the leg extension member is in turn forced into surface-to-surface contact with the leg frame member. The leg extension member is positionally adjusted to, and retained at, any particular longitudinal position with respect to the leg frame member simply by untightening the actuator screw, adjusting the disposition of the leg extension member relative to the leg frame member, and retightening the actuator screw.

Abstract: Power consumption of a mobile terminal is reduced by providing a system wherein a base station specifies a time period, at the end of which a mobile terminal that is hibernating in a power-saving mode will listen for paging messages from the base station. If no paging messages are present, then the mobile terminal continues hibernating, thus conserving battery power by not communicating with the base station. Either the base station or the mobile terminal can initiate a process to transfer the mobile terminal from an awake mode to a hibernating mode. In accordance with another embodiment of the invention for use in systems that require frequent connectivity testing, an agent can be provided within the base station to answer connectivity test inquiries on behalf of the mobile terminal. The mobile terminal can communicate periodically with the base station to update information that the agent uses to respond to the test inquiries.

Abstract: The present invention is essentially a method and system for leaving and retrieving messages at specific coordinate way points within a commercial mobile radio service (CMRS) provider network. Users carry or transport interface devices for communicating over the network and are able to record and view messages at specific coordinate locations while traveling in the network. The location of the device is calculated by the device or by the network while the device is powered on and in within the physical boundaries of the network, or through a combination of both. Messages can be made available to network subscribers when their interface devices come within an area centered about a physical coordinate location. Personalized messages can also be left by subscribers at any coordinate point within the boundaries of the network. The invention can also be used to facilitate access of information about an asset when a technician comes within a physical proximity threshold relative to said asset.

Un traitement thermique supplémentaire, facultatif mais préféré, du corps inorganique façonné permet d'éliminer le substrat organique, et d'obtenir un corps inorganique qui imite fidèlement la porosité, la forme et d'autres caractéristiques physiques du substrat organique. Des substrats inorganiques peuvent également être utilisés avec une bonne efficacité.
