Abstract: A surfactant having the capacity of reducing the surface tension in pulmonary alveoli significantly is provided. The surfactant consists essentially of, based on the total weight of the surfactant, 50.6-85.0% of choline phosphoglyceride, 4.5-37.6% of an acid phospholipid, 4.6-24.6% of a fatty acid or its analogue and 0.1-10.0% of a lipoprotein derived from the lung of a mammal. These components co-operate to form a kind of film at a gas-liquid interface within pulmonary alveoli and reduce the surface tension. A pharmaceutical composition comprising the surtactant is useable for the clinical treatment of respiratory distress syndrome.

Abstract: Apparatus and a method for measuring moisture in plastic pellets employing microwaves transmitted through volatiles, including water vapor driven from such a polymer- sample by heating same in a closed test cell.A pump is used to move a predried gas and those volatiles at an established pressure level and known flow rate to a microwave transducer. The transducer has a pair of antennae horns aimed at one another and each respectively supporting a microwave transmitter oscillator and receiver detector. The volatiles are the test sample which are brought transversely across the open end of the oscillator antenna horn by means of a conduit which is transparent to microwave energy. The particular orientation of the conduit is important to the accuracy of the measurement. A moisture absorbent material is inserted axially into the conduit to restrain the flow of volatiles through the conduit changing the vapor to liquid form. Consequently, there is resident time for the water sample in the path of the microwave energy between the transmitter and detector. The loss of microwave energy due to the vapors in the volatiles is measured at the output through the detector. The transducer through which the microwave energy passes is surrounded by a microwave energy absorbent material whereby all of the energy transmitted is either received by the detector or absorbed by the absorber or water vapor in the test sample. Calibration of the <sub>'</sub> system is obtained by adjusting a zero control and setting a sensitivity control both of which influence the electronic cir- cu<sup>i</sup>try that converts output to a readable form.The method requires the steps of producing volatiles from a polymer sample; transmitting them with a dry gas at a known flow rate and pressure to be acted upon by microwave energy passing between a transmitter and detector; surrounding the environs of the oscillator and detector with a microwave absorber to control the transmission of microwave energy between the oscillator and the detector; measuring the loss of microwave energy at the detector which is a consequence of the water moisture from the volatiles; absorber in the flow path of the volatiles to control the resident time of the water within the transmitted microwave energy.

Abstract: An electromechanical transducer comprises a fixed part and a part rotatable about an axis. One of these parts includes an assembly of aircore coils which are distributed about the axis. Each coil is divided into two parts, each of which comprises two active coil segments intersected by the magnetic field upon rotation of the transducer. The two parts of each coil are furthermore arranged so that the effects of mutual inductance of the active coil segments of one coil part upon the other are reversed relative to the effects of self-inductance in each part.

Granted: 1989-02-23
Abstract: In a central heating system, the temperature (tw) of the heating fluid is controlled depending on the outdoor temperature (tu) and the indoor temperature (ti). A non-linear operating graph presenting the relation between the outdoor temperature (tu) and the heating-fluid temperature (tw) is approximated by a sequence of linear sections (a, b, c, d) of different steepness, the location of the transit points between the sections being determined by the difference between the desired reference temperature (to) and the sensed indoor temperature (ti). Thus, the system optimizes the heating curve in a self-adaptive way.

Abstract: An analyser for the compsn. of the exhaust gases of an i.c. engine, based on the light absorption, uses a chopper for the beam directly after the source of light.  For each gas component to be measured, provision is made for its own measuring cuvette, its own radiation filter and its own detector.  A distributor downstream of the chopper applies the light radiation to all cuvettes.  Pref. the exhaust gases flow from the inlets to the outlets in parallel through five cuvettes to measure CO, CO2, Cn, Hm, NO and NO2, respectively.  Bandpass radiation filters precede radiation detectors and amplifiers.  The first four receive ir. light from the lamp; the NO2 path is operated by uv. light from the lamp because NO2 absorbs little ir. radiation. A polariser is followed by a Pockels cell with a driver, another polariser and an optical fibre light distributor.
