Abstract: ABSTRACT OF THE DISCLOSURE             A process is disclosed for producing free-flowing pellets of ethylene terephthalate oligomer. In the process a molten ethylene terephthalate oligomer having an intrinsic viscosity of from about 0.08 to 0.15 is forced through a plurality of orifices of an orifice plate under pressure into an inert gas zone to form jets of the oligomer which dissociate into spherical droplets under the influence of surface tension.  The droplets are allowed to fall through the inert gas zone into a body of water about 20 to 40 inches from the orifice plate to solidify the droplets into pellets.  The pellets are then removed from the water.

Abstract: A b s t r a c t The fluidized bed is situated in a combustion chamber (1) formed from evaporator tubes (7) welded in sealing-tight relationship, the combustion chamber leading into a gas flue (14). The combustion chamber (1) is connected to the gas flue (14) of smaller cross-section via two inclined connecting wall surfaces (8, 9). Heater tubes (52, 53) bent into an L shape extend through the fluidized bed.          Each shorter limb (58, 59) of the heater tubes (52, 53) extends substantially vertically while the other longer limb (60, 61) extends substantially horizontally. The horizontal limbs (60, 61) pass through a substantially vertical combustion chamber wall (4, 5) at the level of the fluidized bed and the vertical limbs (58, 59) pass through the free surface of the fluidized bed beneath the connecting wall surface (8, 9). The heater tubes (52, 53) are connected to a collector (55, 57) and to a header (54, 56) disposed outside the combustion chamber (1).       As a result of this arrangement of the heater tubes the stresses therein due to uneven thermal expansion of the heater tubes remain within permissible limits.

Abstract: ABSTRACT OF THE DISCLOSURE     A valveless pump system having two moving parts con-siting of a cylinder with a piston therein defining a pump chamber.  An inlet part communicates with a dip tube which extends into a container and permits the product in the contain-er to pass into the pump chamber.  An outlet port allows for the product thus drawn to be dispensed from the pump chamber.          The pump is actuated by pressure directed axially on the piston, forcing it into the cylinder.  Fitted with a return device the piston is allowed to reciprocate in the cylinder alternating between a suction and compression stroke.  During the suction stroke product is drawn into the pump chamber by way of the inlet port while the compression stroke provides for the dis-pensing of the product thus drawn via the outlet port.  The system is equipped with passages and channels sufficient to accomplish the operation of drawing and dispensing the product in addition to providing for the venting of the container.  The suction stroke provides for air to be drawn through the outlet part from the ambient into the pump chamber, advantageously removing any residual product from the outlet part where this is desirable.  In certain applications the air is drawn into the pump chamber to assist in the dispensing of the product during the compression stroke.  The introduction of air into the pump chamber also assures the presence of an air pocket therein, thereby maintaining a resiliency in the system thereby preventing piston "hang up".  Embodiments of the pump system are disclosed having a vertical pump axis equipped with a verti-cally reciprocal finger actuated button or having either a vertical or horizontal axis with a trigger actuator.  Different cylinder and piston configurations are disclosed facilitating commercial applications of the system.

Abstract: ENERGY SAVER CONTROL FOR    SINGLE PHASE MOTORS        ABSTRACT          A circuit is disclosed for controlling operation of a single phase electric motor to obtain maximum efficiency over a complete range of load conditions for the motor.  Under condi-tions of less than full load, single phase motors waste electricity when full AC power is continuously supplied thereto. At less than full load, the torque requirements of a motor are reduced and therefore the flux can be reduced, thus increasing the efficiency.  An electrical switch, in electrical series with the motor, is used to control the motor flux by reducing the "on time" of the switch and thereby decreasing the voltage applied to the motor.  The ratio of auxiliary winding voltage to main winding voltage is the parameter used in the instant invention to provide a measure of the load condition of the motor and thus operate the electrical switch.
