Patent SE-8204441-D0 (SE)
Inventor: EMBREE M L
IPC: H04M1/26
Filed: 1982-07-23
Abstract: An electronic tone ringer responds to ringing signals on a telephone line while being unresponsive to dialing pulses or other signals on the line. Powered directly from the telephone line the ringer uses current sources to provide a high impedance to the ringer circuitry and an insensitivity to line voltage variations so that reliable operation of the ringer is maintained on long loops and with multiple ringers terminated on the line. A multitone signal for activating an electroacoustic transducer (300) is provided by frequency modulating a single oscillator (500) within the tone ringer. Frequency stability of the oscillator is insured by the use of interrelated constant current sources that provide an insensitivity to supply voltage variations over a wide range. Two of the current sources determine the duty cycle by controlling the charge and discharge current of a capacitor in the circuit. A third current source determines the voltage swing on the capacitor. By varying the current output from the third current source, the generator circuit provides a variable frequency signal.

Abstract: Winnowing of shredded tobacco stem material, or other particulate tobacco material, is effected by metering the shredded stem material from a reservoir and then picking the metered flow to open and separate the particles one from another. The resulting stream of separated individual particles of shredded tobacco stem material is projected into an upwardly-flowing air stream to entrain a desired lighter fraction of the particles and carry it out of the separator device. The undesired heavy fraction falls in the separator device and is collected. The collected heavy fraction preferably is reprocessed to separate agglomerates of shredded stem material present in the heavy fraction into individual particles, which are then entrained in a second upwardly-flowing air stream which subsequently joins up with the first gas stream.

Abstract: A method for guiding a flying object, as a projectile, towards a target and a projectile for carrying out the method. The invention relates to a method for guiding of a projectile towards a target and a projectile for carrying out the method. The projectile has means for guiding the projectile toward a desired target, e.g. by means of control signal for a target seeker. In a given point of the projectile trajectory blades or wings are swung-out from the projectile body, which blades in swung-out positions are shaped as a propeller so that they are driven by the stream of air passing the projectile. In order to guide the projectile towards the target in the final phase of the trajectory the said blades are then adjusted in dependence upon the control signal from the target seeker. In one embodiment, in which the blades are rotatably journalled on the projectile body, the rotational axis of the blades is set in a given angle relative to the length axis of the projectile. This oblique setting between the rotational axis and length axis then will produce a desired force in lateral direction on the projectile. In other embodiments the blade angle, i.e. the angle between the length axis of each individual blade and the rotational axis, or the angle of incidence, i.e. the angular setting of each individual blade around its own length axis, is varied periodically in rhythm with the rotation of the blades in space.

Abstract: Coil and magnetostrictive core are placed in the material whose viscosity is to be measured. A current or voltage pulse is applied to the coil as an input signal. The resultant change in magnetic field causes the length of the core to change. This change is damped by the surrounding material. This causes a change in the electrical properties of the sensor which appears on a time-delayed output signal. The output signal characteristic can be correlated empirically with the viscosity of the material.
