Abstract: ABSTRACT           A motor is disclosed in which the stator winding of, for example, a squirrel cage induction motor, is connected in series with a capacitor so that the capacitor, together with the input voltage, causes the stator core to periodically switch from a nonsaturated to a saturated condition and vice-versa so that the flux density is maintained at a uniform high level.  A second stator winding may be provided in paral-lel with the first stator winding and capacitor which second winding serves to provide increased starting torque and improve the overall operating characteristics of the motor.  Also dis-closed is an embodiment in which an inverter is employed to permit the motor to be operated from a DC source.

Abstract: ABSTRACT     A process is described for the production of high purity, unusually high-crystalline texture petroleum coke from a low sulfur petroleum feedstock selected from the group consisting of virgin crude oil, distillation residuum, cracked residuum or mixtures. The process involves a preliminary heat treatment of the feedstock with removal of non-crystalline substances as pitch or coke, and the subsequent heating of a heavy oil fraction derived from the preliminary heating, following fractionation if necessary, to a coking temperature.  The heated heavy oil fraction is then continuously introduced into a verticle, pressure coking-crystallizer which discharges gaseous light hydrocarbons through an upper outlet and progressively accumulates, in the lower portion of the coking-crystallizer, coke which is being formed.  During operation the coking-crystallizer is treated with an upwardly passing, heated purging gas to prevent clogging.  Once the crystallizer is full of coke crystals, the amount of purging gas injected is increased to expel remaining oily materials prior to removal of the coke from the crystallizer.  The process permits production of a superior quality coke suitable for the production of graphite electrodes to be used in electric furnace steel-making under ultra high power operation. kam

Abstract: ABSTRACT OF THE DISCLOSURE          Disclosed herein is a fluid-actuated, diaphragm pump which is particularly adaptable for use as a fuel pump for a multi-cylinder, two-cycle internal combustion engine and which includes an inlet chamber, an outlet chamber, a first diaphragm separating the inlet chamber into a first pulse chamber and a suction chamber, and a second diaphragm separating the outlet chamber into a second pulse chamber and a pressure chamber. The two pulse chambers are connected to separate sources of regularly cycling or pulsating pressures which are at least 90° out of phase from each other and the two diaphragms are oscillated sequentially, in response to the pressure variations in the respective pulse chambers, between a suction position and a pumping position whereby fluid is first drawn into the suction chamber through an inlet, subsequently pumped there-from into the pressure chamber, and then pumped from the pressure chamber through an outlet.  Each of the diaphragms is biased towards a suction position by a spring disposed in the respective suction and pressure chambers.  The biasing force of the spring in the suction chamber is substantially greater than that of the spring in the pressure chamber so as to boost the suction capability of the pump without hinder-ing the outlet pressure capacity.

In shipping of merchandise, freight payments are made, not only with respect to, weight, but also with respect to volume.  By providing a device which may be inserted in the bag at the point of manufacture, and may be expanded at the point of display by merely pulling a string, the bag may be shipped flat and erected for a suitable attractive appearance at the point of sale.  Thus, a pair of parallel members such as cards are provided which are compressed toward each other and are biased apart by a spring.  A pin, which passes through a locking eyelet in an extension from one side of the interior of one of the cards through to the outer side of the other card locks the cards together.  The pin may be connected to a string which extends outside the bag while the bag is closed.          The retailer may merely pull on the string to pull the pin out from its locking position to permit the spring member to perform the extending operation.
