Abstract: A method, a device, and a composition are disclosed. The method includes providing a polyol blend that includes a polyol resin and an electromagnetic (EMA) additive, providing an isocyanate resin selected such that blending the isocyanate resin with the polyol blend results in an EMA spray foam. The device includes a first compartment containing an isocyanate resin and a second compartment containing a polyol blend, which includes a polyol resin and an EMA additive. The composition includes a polyurethane spray foam and an EMA additive blended into the polyurethane spray foam.

Abstract: A method of preparing MMS messages involves preparing a multimedia presentation on a computer using an industry-standard multimedia format; exporting a file containing said multimedia presentation in said industry-standard format; and processing said file to create an MMS message suitable for transmission over a mobile phone service.

Abstract: In a method of synchronizing first and second data streams, the first data stream acting as a reference stream, elements of the first data stream are displayed along a time line on a display device. Containers for elements of the second data stream are displayed on the display device alongside the elements of the first data stream. The containers are interactively displaced on the display device relative to the elements of the first data stream to align the containers with cue elements in the first data stream. Synchronization markers are generated for the aligned displayable elements relative to the first data stream.

Abstract: The invention is directed to a brake lathe having a device to eliminate or reduce vibration. Various types of dampers may be mounted on the arbor shaft of the lathe.

Abstract: A drum rotation indicator enables a crane operator to sense rotation of a drum, and thereby determine linear movement of a cable, that has one end wound about the drum. This indicator has a cam, that rotates with the drum, and a cam follower, that translates rotation of the cam into linear movement. A readout plunger is located conveniently for the operator's hand, and linear motion that is induced by the cam follower is transferred to the readout plunger by a medium that can be a mechanical linkage, a push-pull cable, or a hydraulic system. In a preferred embodiment of the invention, the cam follower disengages automatically from the cam after linear motion has been transferred to the readout plunger. The linear motion transferring medium also transfers motion from the readout plunger to the cam follower, which pivots into engagement with the cam. The cam has a serrated periphery, to give an instantaneous response, upon rotation of the drum, to engagement of the cam follower with the cam.
