Abstract: Case 4901 PHOSPHONITRILIC CHLORIDE POLYMERS                 Abstract of the Disclosure Linear phosphonitrilic chloride polymers are produced from linear phosphonitrilic chloride oligomers by means of a two-step process.  In the first step a mixture of linear phosphonitrilic chloride oligomer having an average degree of polymerization of at least 4 is heated with an excess of ammonia or ammonium chloride.  Cyclic phosphonitrilic chloride oligomer formed during the course of the first step is removed from the reaction mixture.  After the removal of the cyclic oligomer the reaction mixture is subjected to the second step which involves heating the mixture in an inert liquid solvent (optionally in the presence of ammonia or ammonium chloride) whereby the molecular weight of the linear phosphonitrilic chloride polymer is increased.

Abstract: ABSTRACT OF THE DISCLOSURE:        A method for regulating the temperature during the production of a building-material composition, wherein the substances corresponding to a particular formula are mixed with one another and heat is supplied or removed during the preparation of the composition.  During the whole preparation, the temperature of the mix is measured at short intervals in the region of 0.5 to 30 sec or continuously, with high accu-racy, without contact, and the amount: of heat to be added or subtracted in order to reach the required processing temperature of the composition is calculated.  An amount of heat slightly below the calculated value is always supplied or removed, the amount of heat to be supplied or removed approaching the calculated value asymptotically, preferably in stages, or the whole amount of heat corresponding to the calculated value is supplied or removed at one time.  An apparatus for carrying out the above described method is also provided.  This method and apparatus may be used, for exemple, during the production of cement concrete or asphalt concrete.

Abstract: Abstract Especially for modular conveyor belting that is capable of negotiating both horizontal curves and vertical ones, belt tension is spread across the belt using, for each respective set of interconnected links, a rod which can be cammed vertically against an inclined surface at a lateral margin of the belt as a horizontal curve is negotiated, thereby altering the distance between the links in the set. In various embodiments, the camming force is supplied by a conveyor bed rail surface provided  in the turn, by the gravity force on at least one link in each set or by rotation of the rod.  In preferred embodiments the cam slots are relieved to facilitate cleaning.  Even where horizontal turning is not required, some cammed adjustment is prefer-ably provided, again to facilitate cleaning.

Abstract: ABSTRACT       The partial vacuum produced at the inlet passage of a vortex chamber is employed to move liquid from one compartment to another in order to maintain the level of liquid in at least one of the compartments within a predetermined level of the liquid in the other compartment. In one embodiment, the vortex unit or other suction means develops a partial vacuum at the maximum height of a siphon tube extending between the two chambers, the vacuum drawing fluid from both or at least one of the chambers to the top of the tube thus initiating siphoning.  A sump pump having a negative pressure insufficient to lift the liquid to the maximum height of the siphon tube is employed to deliver liquid to a load and concurrently to the vortex unit to establish the required partial vacuum to initiate siphoning.  The vortex unit may also be located in the siphon tube and may be used as a pump to deliver liquid from only one compartment to another or in another embodiment as a siphon to move liquid in both directions to maintain liquid in the two containers within a prescribed difference in height of one another.

Abstract: ABSTRACT OF THE DISCLOSURE A method of calibrating an analog machining sensor of the varying resistance type which has been deposited on a surface involves depositing adjacent it with great positional accuracy relative to a feature on the surface, discrete machining sensors.  As machining takes place, the discrete sensors' continuities are successively broken as the analog sensor's height is reduced and its resistance increased.  Measuring the resistance of the analog sensor at the time each discrete sensor breaks yields values from which the position of the analog sensor's machined edge can be very accurately related to the position of the feature on the surface.
