Abstract: ABSTRACT OF THE DISCLOSURE         Disclosed is a method for the determination of the hormone human chorionic gonadotropin (HCG), luteinizing hormone (LH), prolactin (PRL) and HCG-like material in an aqueous sample comprising contacting a highly specific receptor for these hormones with an aqueous sample to be tested, providing a means of indicating whether binding has taken place between the receptor and hormone possibly con-tained the sample and observing the indicating means to determine the presence of the hormone in the sample.  PRL may be determined separately or simultaneously with the HCG and LH.  The receptor is a plasma membrane extract from the corpus luteum of an animal which possesses the receptor for HCG, LH, PRL and HCG-like material.  Radioassay indicating means are preferred, according to which competitive protein binding between radioisotopically labeled hormone and hormone present in the sample is radiologically determined.  The method has particular application to the determination to pregnancy in the human female.

Abstract: POSITION SYNCHRONIZATION OF MACHINES     Abstract of the Disclosure:   Apparatus for synchronizing the relative positions of motor-driven machines.  Preliminary to operating the machines in synchronism, the rotors of indi-vidual synchronous  motors that drive the machines are moved to a stop at certain angular positions.  The angular positions are such that when inverter voltage is thereafter applied to the stators of all of the motors from a common inverter, the instantaneous angular position of the stator magnetic field with respect to the respective rotor is the same for all of the motors.  In one embodiment, several machines are synchronized as to position by first operating each at low speed to a home position.  Arrival of each machine at its home position is detected by detecting the simultaneous existence of two signals:  (a) a first signal indicating that the instan-taneous phase of inverter voltage applied to the stator is within a predetermined range, (b) a second signal indicating that the position of the machine  member driven by the respec-tive motor is within a predetermined tolerance range of the home position.  Thereupon, if a third signal indicates that the speed of the motor is below a predetermined threshold speed,a brake is applied to hold the machine in its home position.  After all of the machines reach their home positions their respective brakes can be released and all motors can be energized from a common inverter in order to operate the machines in positional synchronism.
