Abstract: Systems, methods, and computer-readable medium containing instructions for operating a conveyor. One method includes receiving, by a controller, a signal from each of a plurality of substations. Each of the plurality of substations provides power to a motor drive unit driving a conveyor belt of the conveyor. The signal received by the controller indicates whether an isolation switch associated with each substation has been manually operated. The method also includes, when the signal received from one of the plurality of substations indicates that the isolation switch associated with the one of the plurality of substations has been manually operated, transmitting, by the controller, a signal to each of the plurality of substations, the signal instructing each of the plurality of substations to isolate the motor drive unit from a power source.

Abstract: A photovoltaic panel racking system is provided having multiple beams aligned in parallel relation where multiple photovoltaic panels are mounted on top of the beams. The beams have a wave structure with multiple sets of slopes providing multiple mounting points. The photovoltaic panel racking system provides a low cost, easy to install and manufacture photovoltaic panel installation solution for roof tops and other surfaces.

Abstract: An apparatus for fighting a fire comprises a suspendible container (10) having a perforated lower surface (12) each of whose perforations (16) is closed by a heat-sensitive membrane (14) which is capable of rupture at an elevated temperature. The container contains a fire retardant material which is released upon rupture of the membrane. The apparatus further includes an electric heater (22) adjacent the membrane and a smoke detector (24) controlling the heater such that upon the detection of smoke the heater is switched on to rupture the membrane. A second embodiment has at least one further heat-sensitive membrane embedded in the fire retardant material above the first membrane such that a respective layer of fire retardant material lies above each membrane.

Abstract: The disclosed method enables a computer system user to efficiently modify attributes of objects displayed by the system and its software applications. Upon selection of a displayed target object by a user, a pop-up menu appears containing a ‘Set Attributes to . . . ’ option. Upon selection of that option by the user, the system cursor changes appearance, and the user is allowed to locate and select a source object separate from the target object (potentially, in a stored file or display window separate from the file and window containing the target object). Upon selection of the source object by the user, the attributes of the source object are immediately transferred to the target object, the display window containing the target object reappears (if it had been hidden by the action of locating the source object), and the display cursor appearance reverts to its normal form.

Abstract: A method of predicting the cutting speed for machining of titanium alloy comprising the steps of obtaining a first transfer function for a tool system, obtaining a second transfer function for a workpiece system, selecting from the first transfer function a first flexible mode, selecting from the second transfer function a second flexible mode, defining a natural frequency of the first flexible mode and the second flexible mode, calculating a tooth passing frequency using the defined natural frequency, accepting the calculated tooth passing frequency if the calculated tooth passing frequency differs from a second harmonic of a combined system formed of the tool system and the workpiece system and from at least one natural frequency corresponding to the tool system and the workpiece system, calculating a stable spindle speed, defining a cut depth using the calculated spindle speed.

Abstract: This concerns a process for maintaining and using business registry (BR) databases. Such BR's, maintained and/or controlled by businesses designated ‘target’ enterprises, contain entries associated with businesses or individuals seeking consideration for trusted business relationship associations with the target enterprise, such entities designated presently as ‘seeking’ entities. These entries contain ‘member status’ code values designating levels of trust associated with respective seeking entities, and information parameters subject to modification by the target enterprise which effectively constitute criteria for raising and lowering status values assigned to individual entries. A presently disclosed options list mechanism allows the target enterprise to modify the information constituting the criteria for trust status level assignment.

Abstract: A method and system for managing events within a calendar program executing within the data processing system. Selected events are associated with each other. An action is performed on the selected events in response to a completion of one of the selected events. The action performed may be marking the selected events as being completed or deleting the selected events. Similar actions may be performed on the selected events in response to a deletion of one of the selected events.

Abstract: An air mass flow measuring system for measuring flow into an internal combustion engine comprises a throttle angle transducer and further transducers measuring ambient air temperature and pressure as well as the pressure drop across the throttle valve. The signals from these transducers are supplied to calculating circuit which carries out the calculation M=K.sqroot.P.multidot..DELTA.P/T. The values of the coefficient K used in this calculation are derived from an empirically programmed read only memory incorporated in the calculating circuit, such memory storing empirically determined values of K for each combination of a plurality of values of throttle angle and a plurality of values of .sqroot. P.multidot..DELTA.P/T.
