Title: Controlling Crystallizaton of Molded Thermoplastic Materials
IPC: B29C45/02
Filed: 1978-11-15
Abstract: A method and apparatus are disclosed for controlling crystallization in thermoplastic materials, such as polyethylene terephthalate, which crystallize when cooled from melt temperature to glass transition temperature after being injected into a mold cavity. When greater amounts of crystallization are desired, a very high pressure is initially imposed upon the material as it cools from the melt temperature, and then the pressure is reduced proportionally to the reduction in temperature so that a nominal pressure is imposed upon the material at glass transition temperature. When a significantly lesser amount of crystallization is desired, an initial nominal pressure is imposed upon the material as it cools from the melt temperature to a predetermined temperature, at which time the pressure is drastically increased.

Title: A power control system for an electric actuator
IPC: G05B11/26
Filed: 1979-03-30
Abstract: The sequences of energising signals that determine the energisation pattern of the windings of a multiphase stepper motor are generated by a central processing unit and applied to the windings via data latches and appropriate amplifiers.

Title: Timing systems
IPC: G04C23/38
Filed: 1979-05-24
Abstract: A timing system for a lamp 4 or other electrical equipment has a control circuit connected in series between the lamp and an electrical power supply 5 and 6. The system has a switching circuit 1 including an SCR 14 that is switched on to illuminate the lamp when ambient light falls below a predetermined level, and a timing circuit 2 that includes a synchronous motor 30 having two sets of windings 32 and 33 which provide first and second timers respectively.

In operation, when ambient light falls to a predetermined level, the lamp 4 is illuminated and motor winding 32 is energized. After a first predetermined interval the motor driven cam causes the lamp to be switched OFF and changes over switch 40 to cause energization of winding 33 instead of 32 and the motor continues to rotate. After a second predetermined interval has elapsed the motor driven cam is returned to its original setting, switch 40 being returned to contact 41 and rotation of the motor is stopped until the ambient light level falls again. The timing operation is then repeated. <IMAGE>
