Abstract: Metal strip is cast from a casting pool of molten metal supported above the nip between a pair of chilled casting rolls (16). The casting pool is confined by refractory plates (56) engaging the ends of the rolls (16). Molten metal in the casting pool in the vicinity of the end closures (56) is subjected to electromagnetic induction heating by passing electric current through electrical conductors (101) disposed outside the refractory plates (56). Each conductor (101) is in the form of a trapezium shaped loop of metal tube having wide top segment (107) and narrow bottom segment (108) connected by downwardly convergent side segments (109) aligned with roll edges.

Abstract: A control system for controlling the frequency of a laser 1 in an
optical transmission system comprises means 34 for applying a
frequency modulation to the laser, means 35 for determining an
amplitude modulation present in the signal downstream of the laser
and attributable to the frequency modulation, and means 36 for
discriminating a portion of the amplitude modulation which is
substantially in phase quadrature with the applied frequency
modulation, and means 37 for controlling the frequency of the laser
on the basis of the discriminated quadrature portion. An optical
component downstream of the laser may have a response which
converts FM to AM. The response and the frequency output of the
laser can be locked to one another, without errors caused by
unwanted AM in the transmitted signal modulation frequency.

Abstract: An exercise bicycle including a frame having a seat and handlebars, a high-inertia
flywheel having a hub at a center of rotation, the flywheel being rotatably
supported on the frame at the hub, and a drive train including a drive sprocket, a crank
arm attached to and extending from the drive sprocket, and a pedal attached to the

engagement between the sprocket and the hub, and to establish a break-free
force
threshold. When the drive train is actuated in the forward direction, the slave sprocket
and the hub move together, and when the drive train is actuated in the rearward
direction under the influence of a force greater than the break-free force threshold, the
clutch mechanism slips between the slave sprocket and the hub, allowing the slave
sprocket and the flywheel to move independently of one another.

Abstract: The scaleable OFDM system according to the principles of the present
invention provides increased flexibility and adaptability by providing scaling of the
operating parameters and/or characteristics for the OFDM system. For example,
control circuitry can scale the bit rate by scaling of the OFDM symbol duration, the
number of carriers and/or the number of bits per symbol per carrier. Scaleability
permits the scaleable OFDM system to operate in various communications
environments requiring various operating parameters and/or characteristics. By
scaling the operating parameters and/or characteristics of the OFDM system when
control circuitry determines that different operating parameters and/or characteristics
are necessary or advantageous, the control circuitry can dynamically change the
operating parameters and/or characteristics, thereby providing compatibility or the
desired performance. For example, by dynamically scaling the bit rate, widely varying
signal bandwidths, delay spread tolerances and signal-to-noise ratio (SNR)
requirements can be achieved. As such, a scaleable OFDM system is particularly
suitable for application in mobile, wireless communication devices, which support a
variety of services, in a variety of environments, indoor as well as outdoor and in radio
channels with differing bandwidths.

Abstract: A simple downconverting A/D converter utilizing
predictive coding principles. By placing the sampler inside
the predictive loop, the predictive loop filter can be
implemented using DSP techniques, thus eliminating the
complexities introduced by use of discrete-time analog
circuitry. Then, by re-mapping the output of the predictive
loop filter into the analog domain using a D/A converter, the
predictive filter output signal is subtracted from the input
analog signal to generate the prediction error signal.
Therefore, through directly sampling the prediction error
signal and converting the output of the predictive loop
filter into analog representation using a low-cost multiple
bit D/A, the use of discrete-time analog circuitry is
eliminated and the complexity of the converter design is
greatly reduced. Various features of the invention are
disclosed.

Abstract: An optoacoustic modulator contains first and second optoacoustic
media, to which first and second piezoelectric vibrators are attached
respectively. Herein, both of the first and second optoacoustic media are
designed in same measurements, wherein they are arranged in series along
an optical axis of a light signal in such a way that crystal orientation of the
first optoacoustic media differs from crystal orientation of the second
optoacoustic media with an angle of inclination of 90°. In addition, the
first piezoelectric vibrator is attached to a first surface of the first
optoacoustic media which is placed in parallel with the optical axis of the
light signal, while the second piezoelectric vibrator is attached to a second
surface of the second optoacoustic media which is placed in parallel with the
optical axis of the light signal, wherein the first surface is directed
perpendicular to the second surface. The light signal, corresponding to
incoming light incident on the optoacoustic modulator, is input to the first
optoacoustic media. Then, the light signal transmitted through the first
optoacoustic media is input to the second optoacoustic media, from which a
desired output corresponding to outgoing light is output. The first and
second piezoelectric vibrators are controlled by modulation signals, which
are independently adjusted to cancel polarization mode dispersions of the
optoacoustic media. In addition, it is possible to improve ripple
characteristic of loss-wavelength dependency characteristic of the
optoacoustic media, while it is possible to reduce an amount of crosstalk
that occurs at a high-speed modulation mode.
