Abstract: CONTROL SYSTEM FOR DRILLING TOWER            ABSTRACT OF THE DISCLOSURE          An apparatus and method for controlling moisture content of prilled  products which are produced by air drying a spray of the liquid product, comprises a vessel for receiving a flow of air and a flow of the liquid product, a supply line for supplying air to the vessel and a supply line for supply-ing liquid product to the vessel.  The product is advantage-ously a solution of urea.  Moisture content is measured or inferred for the product flow, the input air and the air coming out of the vessel.  An air flow controller is connected for controlling the flow of air into the vessel which control-ler is itself controlled by a circuit that calculates a desired air input flow rate for a selected moisture concentr-ation in the prilled urea product.

Abstract: ABSTRACT        In bowling establishments, the bowling balls being returned on a ball return race must be lifted to a higher level in the vicinity of the player's position.  This is effected by means of a belt drive, which is seated on a pivotable ball lift mechanism (6).  If a ball (3) is not engaged by the belt (9), a feeler causes the arm (12) of the pivotable mechanism (6) to be lowered, as a result of which the ball is engaged by the belt (9) and is transported obliquely upward along the return race (2).  As a result of this upward movement of the ball (3), the pivotable ball lift mechanism (6) is pivoted in the direction of the arrow A and the latch arm (22) again locks into place behind the latch (32), so that the pivotable ball lift mechanism (6) subsequently assumes its normal position. The operational reliability of the apparatus is thereby increased, because even balls (3) rolling quite closely to one another are lifted with assurance to the proper level.                            (Fig. 5)

Abstract: Abstract A commutatorless DC machine (10) is disclosed having axially oriented magnetic flux in the air gaps between interleaved stator and rotor disks, wherein the rotor disks (16) carry one or more radially oriented armature winding elements (32) consisting of electrical conductors serially interconnected in serpentine fashion and terminated at a pair of slip rings (30F/R). The magnetic flux incident upon the two opposed planar surfaces of any one rotor disk are oppositely directed thereby producing electro-motive forces or torques which are directly additive, resulting in heretofore unrealized electromechanical transducer actions. A number of illustrative and preferred embodiments describe single or multiple rotor disk configurations; also describe armature winding arrangements having various numbers of indivi-dual armature winding elements arranged in parallel between the slip rings; and further describe an improvement wherein a number of basic units are combined into a tandem arrangement (400).  The resulting DC machines exhibit superior electrical and mechanical performance due to, among other factors, the absence of limita-tions imposed by commutation; and also may be designed for a wide range of electrical and mechanical requirements simply by the addition or deletion of disk sections and/or armature winding elements and/or tandem units.

The voltage across these resistors (108,109) is amplified by a first opera-tional amplifier (110), whose output voltage is applied to a converter circuit (120), which converts said voltage into two opposite-phase output currents, which are applied to the interconnected emitters of the first (101) and second (102) current distribution circuits.

The collectors of these transistors (112,113) are connected to a third (114) and a fourth (115) resistor respectively.  The voltage across these resistors (114,115) is amplified by a second operational amplifier (116) whose output voltage (uo) is applied between the bases of the two further transistors (112,113).  This output voltage (uo) also forms the output voltage of the arrangement.  This output voltage (uo) is related to the control voltage (ust) in accordance with an exponential function over a wide range of control voltages.
