Abstract: ABSTRACT OF THE DISCLOSURE           A vaporizer and burner unit for an  oil or kerosene space heater comprises three elongated, vertically stacked fuel mixture flow chambers A, B and C respectively defined between a lower U-shaped frame member 19b and the sloping bottom wall 26 of a flanged, upper U-shaped frame member 19a nested on the lower member, between the wall 26 and an inverted V-shaped pressure plate 27 having a plurality of fuel mixture feed holes 28 therein, and between the plate 27 and a burner plate 30 having a plura-lity of flame slits 31 therein.  Fuel is fed into one end of the chamber A onto a heated vaporizer block 21, and combustion air blown in through a side window 24 adjacent the block and through a concentric gap 25 around the fuel supply line 12 mixes with the vaporized fuel and flows down chamber A and into chamber B through an end opening 29.  The mixture then disperses through the holes 28 into chamber C and through the flame slits 31 to a spark igniter 62.  Secondary combustion air is blown up through holes 32 in the upper frame member flanges and funneled into the flames by converging guide plates 33 mounted on the flanges.  The zig-zag flow chamber arrangement implements thorough fuel-air mixture and preheating, and the holes 28 and 32 are staggered with respect to the slits 31 to promote uniform and complete combustion.

Abstract: ABSTRACT OF THE DISCLOSURE         A receiving system includes a linear array of receivers, each of which is responsive to incident stimuli for producing an output signal, and signal processing means for processing the output signals to provide the array with pre-selected directional rejection characteristics.  Such processing includes obtaining sum and difference signals from the outputs of pairs of the receivers, integrating the difference signal, and combining the integrated signal with the sum signal such that stimuli incident on the array at a predetermined angle and at a predetermined frequency are substantially rejected.  The angle and frequency at which rejection takes place are selected on the basis of the spacing between the pairs of receivers whose outputs are added and subtracted, and on the basis of the relative gain applied to the integration and sum signals before they are combined.

Abstract: ABSTRACT OF THE DISCLOSURE           A control system for a fabric drying apparatus comprising a resistive heating element in series with high limit and cycling thermostats and connected across the two power lines of a three wire alternating current power supply. The drive motor of the timer is electrically connected between the junction of two legs of the heating circuit and the neutral wire of the power supply. The impedance of the timer drive motor is high compared to the resistance of the heating element; therefore, when the heating element is energized for drying fabrics, the current flow to the timer drive motor is negligible and the timer will not advance. When the cycling thermostat in one of the legs opens at a predetermined temperature, the heating element will be deenergized and current will flow in the other leg and neutral line and the timer will advance until the thermostat closes to reenergize the heating element.

Abstract: ABSTRACT OF THE DISCLOSURE         A process is provided for the production of a substantially crystallographically pure polymorphic form of cimetidine having the struc-tural formula   Such cimetidine is characterized by an infra red spectrum (1% KBr disc) having very strong, broad peaks at 1400 and 1385 cm-1, a strong, sharp peak at 1205 cm-1 and a medium-sharp peak at 1155 cm01 and having no peak at 1180 cm-1.  The process includes dissolving cimetidine in a hot, non-aqueous solvent, e.g., acetonitrile, acetone, methylisobutylketone, toluene or a lower alkanol.  The resultant solution is cooled with sufficient agitation to ensure efficient heat transfer to yield a suspension of cimetidine A in the solvent.  The suspension is now characterized by good handling properties.  Finally, the cimetidine A is separated off.  Such-cimetidine A is more easily obtainable in a crystallographically pure state.  It is also slightly more water soluble than either of the other forms, and preferably has a rate of dissolution at 25°C. from the flat sur-face of a standard compressed disc of at least 0.20 mg/min/cm2.  A further advantage is that such cimetidine A is rather more easy to handle, parti-cularly in large scale operations, such as centrifugation.

Abstract: ABSTRACT           In a teleprinter equipment, a method and arrangement to transmit messages between a station and a teleprinter ap-paratus by feeding D.C.-pulses, representing binary coded char-acters in the message, through a line interconnecting the station and the teleprinter apparatus.  The line has a capacitance depend-ent upon the length of the line.  The method is characterized in that the current is regulated, at least in an interval follow-ing the closing of the line path at the beginning of a current pulse, by means of a variable impedance element included in series with the line path on the transmitter side.  The variable im-pedance element is controlled such that the impedance value of the impedance element assumes a high value immediately after the commencement of current flow due to the closing of the line path and thereafter rapidly decreases to a low value, which is main-tained during the pulse.  The variable impedance may be a con-trollable semi-conductive element included in a constant current generator.  This semi-conductive element is brought to a high impedance value in the transient intervals immediately after commencement of current flow and then its impedance value is decreased.

Abstract: ABSTRACT OF THE DISCLOSURE   Voltage, current and field voltage of a generator connected to an electric power system are sampled at a predetermined period for analog-digital conversion and then led to a digital computer.  In addition to computation for AVR, the computer computes from its input the generator output power, and also monitors the occurrence of a fault, the removal of the fault and variation in the generator output in the system.  After the occurrence of a fault, the field excitation of the generator is intensified until the generator output power reaches substantially a peak value, but after the peak value is substantially passed by, the excitation is conversely depressed to a value below the level which is present before the fault occurs.  When the generator output power recovers the value which is present before the fault occurs, the computer returns to deliver the AVR output.

Abstract: A B S T R A C T            A viscous fluid clutch employing a magnetic field selectively actuatable by a heat sensing device to operate a valve arm to seal an inlet passage fluidly communicating an operating chamber with a storage chamber.  The clutch includes a clutch and a housing member rotatably disposed relative to one another.  Each member has a shear surface.  The surfaces define therebetween the operating chamber.  The storage chamber is located in the housing member and is in fluid com-munication with the operating chamber via a discharge passage and the inlet passage.  Pump means in the operating chamber displace fluid through the discharge passage from the operating chamber to the storage chamber.  The inlet passage directs fluid from the storage to the operating chamber.  A movable valve arm selectively seals the inlet passage.  The valve arm is moved via a solenoid action in response to actuation of the magnetic field.  Fluid is disposed within the clutch and is used, when located in the operating chamber, to rotate the housing members in response to rotation of the clutch member.  When the fluid is displaced from the operating to the storage chamber, rotation of the housing member is reduced.          This invention relates generally to viscous fluid clutches and more particularly to viscous fluid clutches which are actuated by a magnetic field in response to temperature changes in a sensed medium.
