Abstract: ABSTRACT OF THE DISCLOSURE           A modem including a modulator section for converting a bit stream into a phase modulated inter-mediate frequency (IF) signal and a demodulator section for converting a similarly converted phase modulated IF signal into the bit stream from which the phase modu-lated IF signal was converted.  In the bit stream each given number of successive bits defines a symbol.  In the modulator section, each symbol is phase modulated by DPSK conversion.  The phase modulated symbols are digi-tally filtered by a FIR digital filter to provide a filtered signal that, when converted into an analog signal, provides a modulation signal of a modulation frequency that is centered about a predetermined frequency and deviates therefrom in accordance with the value of the phase modulated symbol.  The filtered signal is converted into an analog signal and mixed with a steady-state signal at a predetermined frequency to provide a phase modulated IF signal that is a frequency modulated (FM) signal having an IF frequency that is a modulation product of the modulation frequency and the predetermined frequency.  In the receiver section, a FIR digital filter for reconstructing the phase modulated symbols from a received digital signal includes a microprocessor for filtering of the received digital signal, and the micro-processor includes a memory for storing FIR filter coefficients for use in the filtering of the received digital signal.  The modem is operable in a training mode wherein a sequence of predetermined symbols is provided to the FIR filter in the modulator section and the phase modulated IF signal provided by the modulator section is provided to the demodulator section.  The microprocessor then adjusts the FIR filter coefficients stored in the microprocessor memory until the re-constructed phase modulated symbols correspond to the sequence of predetermined symbols provided to the FIR filter in the modulator section.

Abstract: A DIGITALLY CONTROLLED WIDEBAND PHASE SHIFTER     ABSTRACT OF THE DISCLOSURE   A digitally controlled wideband phase shifter is disclosed in which an input signal is resolved into two quadrature related components, the components are scaled in a stepped digital manner in proportion to the sine and cosine of the phase shifting angle, and then recombined to reconstitute a phase shifted replica of the input signal.  The scalers are segmented MESFETS of a dual gate design in which each segment, has a predetermined transconductance and may be gated "ON" or "OFF" by a control signal to affect the overall trans-conductance of the scaler, and thereby the scaling factor.   The phase shifter is implemented by a monolithic microwave integrated circuit technique in which the preferred substrate material is gallium arsenide, and in which all active device and circuit features are formed on the substrate by a photolithographic process.  The phase shifter is adapted to scaling at stepped angles, typically 11-1/4 or 22-1/2 degrees, is broadband and is applicable to frequencies ranging from a fraction of a gigahertz to many gigahertz.

Granted: 1990-04-24
Abstract: ABSTRACT       A mouthpiece through which a person may breathe has a sealing flange for introduction into the mouth. The sealing flange has an upper portion for lying against the hard palate and a lower portion for fitting between the lower lip and the anterior surface about the lower teeth and gums. The juxtaposition in the mouth of the upper portion against the hard palate and the lower portion seated in the lower vestibule portion of the mouth results in the sealing flange forming an effective seal and the sealing flange being comfortably held in place in the mouth even when the mouth is open to the extent of the normal relaxed muscle tone of the mouth. To facilitate the seal when the mouthpiece is introduced into the mouth, a tooth tray is provided. Another aspect of the invention permits the mouthpiece to envelop the nostrils such that when the mouthpiece is in place all inspired and expired air must pass through the mouthpiece. In the best embodiment of the invention, the nostrils are enveloped by a naso-labial hood which envelops the entire nose forming a seal against the outline of the nose, whereby minimizing the non-respiratory tract dead air space inside the volume of the naso-labial hood. The naso-labial hood and the upper portion of the sealing flange lying against the hard palate are biased one towards the other so that the naso-labial hood integrated with the mouthpiece grips the face to remain in place without the assistance of straps.

Abstract: Superabsorbent gel compositions useful as plant growing media additives are prepared from a copolymer of acrylamide and acrylic acid salt in a molar ratio of 70:30 to 95:5, cross-linked such that less than 30% by weight of the dry polymer is water-soluble and the gel can absorb releasably at least 15 times its own weight of water. The gel composition is therefore tailored to the needs of an agricultural/horticultural context because it has long-term stability in natural soil, low solubility that would otherwise lead to poor soil properties, and good water absorbency. Preferred gel compositions in foam form are described.

Abstract: A cylindrical cutter head for a wood planing machine has mounted in its circumference a number of disposable knife blades which are clamped in place with the help of centrifugal wedges in lengthwise grooves. Between each disposable knife blade and each centrifugal wedge there is positioned a bracket of L-shaped profile consisting of a base strip which is immovably attached to the cutter head body and a clamping strip bearing against the knife blade, this clamping strip being elastically deformable to a small extent. By means of a conformal relation of a profiled region of the disposable knife blade with a corresponding profiled region of the clamping strip, the disposable knife blade is held firmly in position when clamped in. After loosening of the centrifugal wedge, the disposable knife blade can be easily withdrawn in a lengthwise direction and can be replaced with accurate positioning.

Abstract: Control circuit for multifunction change-over switch. A control circuit for a multifunction change-over switch in a transmitter-receiver comprises means 135 of detecting activation of the change-over switch 120 and means for monitoring the status of the receiver 69. A timer 230 which reacts to the control devices and the detector, creates a predetermined interval of time after the activation of the change-over switch or each received message of a predetermined type. When the change-over switch is activated during the interval of time, the transmitter 80 is connected in. When the change-over switch is activated outside the interval of time, an audio circuit is activated so that the user can control the channel. During the first change-over switch activation during a given interval of time a code circuit 100 is connected in. For subsequent activations of the change-over switch during the same interval the code circuit is blocked. This allows a single change-over switch to perform several send and receive functions. <IMAGE>

Abstract: In an inverter controlled with a firing unit connected to switches and defining an operating frequency, a resonant frequency of a series oscillating circuit of the inverter connected to one of the switches is placed below this operating frequency. Given this operating situation, a short of the d.c. voltage source is impossible. Given, for example, unfavorable component tolerances, however, the operating frequency can be moved close to the resonant frequency and cause impermissibly high voltages at the components. Such a voltage rise is limited according to the invention by means of a voltage-dependent resistor. It preferably lies in series with a capacitor and takes care of a voltage-dependent shift of the resonant frequency.
