Patent SE-8102483-L (SE)
Inventor: HARFORD J R
IPC: H03G1/00
Filed: 1981-04-16
Abstract: A gain-controlled amplifier is provided having a broad range of gain control which is traversed by varying the collector impedance of a common emitter coupled amplifying transistor. The collector load impedance of the transistor includes a controlled resistance device having a base electrode coupled to the collector electrode of the amplifying transistor, an emitter electrode coupled to receive a variable gain controlling current and a collector electrode coupled to a point of reference potential. At signal frequencies, the base-to-emitter junction of the device acts as a resistance which varies inversely with the flow of gain controlling current through the collector-to-emitter path of the device. Varying the resistance of the base-to-emitter junction of the device varies the collector load impedance of the amplifying transistor, whereby the gain of the transistor is varied by changing its load line as a function of the A.C. resistivity of the device. The collector-to-emitter path of the device through which the gain controlling current flows is separate from the transistor biasing circuitry, and hence control of the device will not affect the D.C. biasing of the amplifying transistor.

Abstract: A two-stroke engine is disclosed which is controlled by a carburetor throttle valve and has a crankcase subjected to continuously alternating overpressure and underpressure. A pneumatic control member responsive to a signal dependent on the rotational speed of the engine is in pressure communication with the inner chamber of the crankcase via a valve. The output member of the pneumatic control member is connected with the throttle flap of the carburetor. The valve provided between the crankcase and the pneumatic control member is responsive to a signal for controlling the pressure in the pneumatic control member. This valve can be configured as a resonance control valve fixedly mounted to the housing of the engine. The resonance control valve has a mass oscillator which, at a correspondingly high engine speed and as a result of the vibration frequency associated therewith, acts upon a sealing diaphragm in the resonance control valve to open a pass-through opening communicating with the pneumatic control member.

Abstract: The two parts in each pole pair have opposite polarity to one another, and armature windings are likewise divided into two parts with opposite polarity with the same position as each other along the direction of rotation, but with different positions along the shaft. A three-phase non-synchronous motor can be used as generator since it is driven by something other than current, so that its speed is higher than that synchronous. - The two parts of each stator pole are each wound in their own direction, and the windings are series connected to each other to form a double pole, being counter poles to each other both externally and internally. Accordingly, the magnetic stator pole parts which are outside from the armature in each stator winding have a short connection with each other of magnet core material instead of requiring a longer connection with other stator poles.

Abstract: Sulfite spent liquor is subjected to a two-step chromatographic separation to form substantially purified fractions of sugars and lignosulfonates. The process for the separation of sugars and lignosulfonates comprises the steps of (a) introducing sulfite spent liquor with a pH of 2.5 to 3.5 onto a chromatographic column containing a resin in metal salt form; (b) eluting the sulfite spent liquor from the column with water to recover a substantially sugar-free lignosulfonate-rich fraction and a sugar-rich fraction; (c) collecting the sugar-rich fraction for further purification; (d) adjusting the pH of the collected sugar-rich material to between 5.5 and 6.5 and introducing the material onto a second chromatographic column containing a resin in monovalent salt form; and (e) eluting the sugar-rich material from the second column with water, whereby a second sugar-rich fraction and a second lignosulfonate-rich fraction are formed. By this method, essentially all of the lignosulfonate is recovered in fractions which are substantially free of sugars, and essentially all of the sugars are recovered in a fraction which is substantially free of lignosulfonates.

Abstract: The powdering medium, the reducing gas atmosphere and fluid used comprise hydrocarbons, pref. gas-form or liq. hydrocarbon or a mixt. such as gas oil, oil, benzene, or similar. The quantity of reducing powdering medium per time unit is adjusted in relation to the amount of metal per time unit, so that the desired carbon content in the produced metal powder is obtd. A molten stream is thus exposed to the gas-form or liq. hydrocarbon and to protect the powder against oxidation, the pulverisation takes place in a closed granulation chamber partially filled with liq. medium and under excess pressure of gas-form reducing medium. This obviates also any possible risks of explosion. The granulation chamber is connected via a base tapping-off arrangement to a vessel contg. a metal smelt. In the upper part of the chamber is an inlet for reducing gas, and there is a mouthpiece inserted for the supply of reducing powdering medium. A fluid lock comprises a pipe communicating with the chamber via a valve, and which issues below fluid level in the lock.
