Abstract: ABSTRACT OF THE DISCLOSURE      The invention relates to a process for making red phosphorus by subjecting molten yellow phosphorus to a thermal conversion reaction in a closed reaction zone. To this end, a hollow shaft-provided and closed ball mill is preheated to a reaction temperature within the range 280 to 590°C. Yellow phosphorus is continuously introduced into the ball mill through the hollow shaft in quantities per unit time through the hollow shaft temperature prevailing inside the ball mill to be main-tained without supply of heat from the outside. More particularly, decreasing quantities of yellow phosphorus are introduced per unit time at increasing temperature and increasing quantities of yellow phosphorus are in-troduced per unit time at decreasing temperature within the limits specified. Red phosphorus is allowed to cool inside the ball mill, water is poured over it and the whole is subjected to wet-grinding.  An aqueous sus-pension of red phosphorus is finally removed from the ball mill.

Abstract: D-3,200  C-3,132 ENGINE CHARGING SYSTEM WITH DUAL FUNCTION CHARGE SUPPLYING AND CHARGE COOLING BLOWER          Abstract of the Disclosure A two-stroke cycle turbocharged internal combustion engine is provided with a dual core after-cooler and a dual function positively driven blower which at low engine loads is connected to provide necessary charging air to the engine air intake preferably through the inlet of the turbocharger compressor.  During periods of high-load operation, when the turbocharger energy is alone sufficient to provide the engine inlet charge, the blower is reconnected to direct cooling air through the aftercooler system thus lowering the temperature of the inlet charge under high-load conditions.  Numerous variations and modifications of the concept are disclosed.            RJO/pgm

Abstract: ABSTRACT OF THE DISCLOSURE           Randomly distributed pieces of piece goods in a state of translatory movement are identified and classified on the basis of a physical property thereof.  The travel path of the piece goods is observed with a detector scanning the path transversally and being suitable for the physical property in question, said detector delivering an electric signal analogous with the observed  physical quantity at each spot of the scanning line, as determined by the resolution of the detector.  Thereupon, the electric signals are processed continuously in the real time and converted into bynary key number groups belonging individually to each piece in the scanning line, the key number groups are processed recursively during the passage of the pieces in classifying units reversed for each piece during the passage thereof and the classification is carried out on the basis of the key number group.  Finally, upon completion of the passage of the piece, the corresponding classifying unit is released to perform the classification of a new piece having arrived in the scanning line of the detector and being randomly situated therein.

Abstract: A B S T R A C T   An air-cleaning, heat-exchange apparatus includes a main housing portion connected by means of an air inlet fan to the kitchen exhaust stack of a restaurant.  The apparatus includes a pluralitly of heat exchangers through which a heat-absorptive fluid is circulated, simultaneously, by means of a suitable fluid pump.          These heat exchangers absorb heat from the hot exhaust gas, out of the exhaust stack of the restaurant, which flows over and through these heat exchangers and transfers this heat to the circulating fluid which communicates with remote heat exchangers.  These remote heat exchangers further transfer this heat to a stream of air, such as that from a cold-air return duct for supplementing the conventional heating system of the restaurant.  Due to the fact that such hot exhaust gas is heavily grease laden, grease will be deposited on viurtually all internal surfaces of the apparatus which this exhaust gas contacts.  Consequently, means are provided for spraying these contacted internal surfaces, as well as the hot exhaust gas itself, with a detergent solution in which the grease is soluble, thereby removing grease buildup from these internal surfaces.

Abstract: PHN. 9659 ABSTRACT:       Amplitude modulator circuit for modulating a video signal on a carrier signal. A first control loop which is coupled to the output terminal of the modulator comprises a first sampling circuit which is active during reference signal portions for generating a direct current compensation signal which is added to the video signal. As a result thereof the signal at the modulation input terminal of the modulator obtains a value for which, during the sampling interval, the signal at the output terminals is substantially independent of the signal at the carrier input terminal. A second control loop which comprises a second sampling circuit which is active dur-ing reference signal portions, generates a second direct current compensation signal which is added to the signal at the output terminal. This eliminates an effect of a variation in the direct voltage level at the output terminal, while the circuit automatically eliminates sub-stantially the effect of an unbalance in the modulator.

Abstract: METHOD AND APPARATUS FOR MEASURING AND CONTROLLING    FLUID FLOW RATES            Abstract or the Disclosure To measure the flow rate of a fluid in a pipe, a heat pulse is injected into the fluid by a heat pulse generator, and the time of flight of the pulse between the generator and a sensor is measured.  Arrival of the pulse at the sensor is determined by detecting a selected temperature level of the ascending flank of the pulse, and a predetermined temperature level of the descending flank is then detected to initiate generation of the next subsequent pulse.  Since the temperature of the descending flank generally represents the temperature of the fluid between the heat pulse generator and sensor, the technique ensures that the accuracy of each successive flow rate measurement is not affected by residual heat from the preceding measurement, and yet enables measurements to be obtained at maximum frequencies.  In one embodiment the measurements are used to control the flow rate of the measured fluid, and in another the flow rate of fluid in one or more additional pipes.

Abstract: ABSTRACT       A stackable thin-walled cup is designed to absorb telescoping Loads with less risk of jamming and is for use in beverage dispensing machines with an ingredient held in the cup. An ingredient is retained in the base of the cup which has an inward projecting annulus with upper and lower surfaces arranged to co-operate with surfaces     of an outwardly projecting annulus at the base of a second stacked cup. Two of the surfaces form a seal to prevent Loss of ingredient and they  are held in contact by a force due to abutment between abutments on respective cups. By suitable difference in linear dimension between the surfaces and abutments, a force is produced by tension derived from the cup walls to hold the seal surfaces together. Telescopic shock loads produce compression on the abutments and momentarily separate the seal surfaces which re-engage on removal of the Load.
