Abstract: A method for forming a pattern in an abradable coating includes the step of machining a groove in the abradable coating with a machining tool. The machining tool is configured to machine a top surface, a side surface and a bottom surface of the groove simultaneously. A repeating step repeats the machining step until a desired number of grooves is obtained in the abradable coating.

Abstract: A method and apparatus for presenting an information signal such as an image signal or a sound signal using a plurality of signal sources. The plurality of signal sources are located within a predetermined space, and the method comprises receiving a respective positioning signals from each of said signal sources, generating location data indicative of locations of said plurality of signal sources, based upon said positioning signals, generating output data for each of said plurality of signal sources based upon said information signal and said location data, and transmitting said output data to said signal sources to present said information signal.

Abstract: An agricultural vehicle and method of operating the same, where the agricultural vehicle has an engine, a continuously variable transmission, a processor, an inching controller, and a speed controller. The speed controller sends a first signal to the processor, and the processor controls the transmission to operate the vehicle at a first speed based on the first signal. The inching controller sends a second signal to the processor, and the processor controls the transmission to move the agricultural vehicle in a forward or reverse direction, depending on the second signal. If the first speed based on the first signal is zero, the second signal triggers the processor to control the transmission to move the agricultural vehicle in the forward or reverse direction a predetermined first distance. The control of the vehicle to be at zero speed or to be in a particular position is effectuated by a position control mechanism.

Abstract: There is described a process for adhering a first elongate foam element having a first end portion to a second elongate foam element having a second end portion. The process comprises an initial step of melting a first surface portion of the first end portion to produce a first molten portion. Next the first end portion is abutted to the second end portion. Thereafter, the first molten portion is caused to solidify to create a seam bond between the first end portion and the second end portion. Thus, the present invention relates to adhering two elongate foam elements together at their end portions. The bond between the foam elements is created by melting at least a portion of the surface of one or both of the end portions of the two foam buns. This creates insitu a molten region which acts as an adhesive when the end portions of the two buns are abutted or otherwise contacted with each other.

Abstract: A bearing arrangement is provided in which bearings (60) are held captive between opposing bearing surfaces of laces (24, 62). A closeable delivery hole (64) provides a route through which bearings can be inserted into or removed from the space between the races (24, 62). A ball rake (54) is moveable into engagement with the bearings (60) and is rotatable so as to sweep the bearings towards the delivery hole for removal.

Abstract: A circuit and method for compressing or generating a pulse, particularly a chirp pulse, which uses infinite impulse response filtering (3.2). The infinite impulse response filters (3.9, 3.10, 3.11, 3.12) simulate the responses of finite impulse response filters. This is achieved by pre-processing the signal by passing it through a pre-processing filter (3.3) which has zero response at the resonant frequencies of the infinite impulse response filters (3.9, 3.10, 3.11, 3.12). The pre-processing and infinite impulse response filtering may be incorporated into a matched filter for detection of a chirp waveform input signal. This can be implemented in the time domain or the frequency domain. The matched filter also can incorporate beating to the base band techniques. The matched filter can also act as a generator by applying a pulse to the input which has the unit impulse function causing a chirp signal, equivalent to the transfer function of the filter, to be produced as the output.
