Title: Reversible variable frequency oscillator for smooth reversing of AC motor drives
IPC: H02P27/10
Filed: 1979-04-27
Abstract: An induction motor 13 is fed by a controlled current inverter whose thyristors T1-T6 are fired by a control circuit 25 including an oscillator 24 having an integrator 33 receiving an inverter frequency command signal 41 derived from the members 14,20,21,22 of a load angle control system and the output of a tachometer 15. The signal 41 has a large ripple component and a small dc component under conditions of low- motor speed and heavy torque or low speed reversal at high or low torque. The oscillator members 33-39 control a ring counter 40 to generate timing pulses at a frequency and in a direction respectively determined by the amplitude and polarity of the DC component. The ripple component provides multipulse operation at low speeds to modulate the inverter output and minimize cogging torque or motor/load mechanical resonance. Also the system provides, for the motor, smooth reversing over a wide range of torque, and for the inverter, reliable commutation at low operating frequency and reduction of harmonic effects (if the inverter is of the voltage source type). The oscillator may be modified to cease operation when over- current is sensed or to operate at a minimum frequency, Figure 6 (not shown). <IMAGE>

Patent GB-2055380-A (GB)
Title: Pre-expanding thermoplastics resin beads and a moulding apparatus
IPC: C08J9/16
Filed: 1980-01-25
Abstract: Thermoplastic resin beads containing a blowing agent are continually agitated in a heated pre-expansion chamber to a temperature near the fusion point of the beads and above the boiling point of the blowing agent at substantially atmospheric pressure; the beads soften and expand; a dry gaseous medium may be swept over the beads to remove moisture and any blowing agent which has escaped. Thereafter the chamber is evacuated until a substantial amount of blowing agent is removed from the beads and the expanded beads are then allowed to return to atmospheric pressure. As a preferred embodiment of the invention, steam may be injected into the chamber prior to evacuation. This serves to further expand the beads, and facilitates the removal of the blowing agent. This embodiment also provides a means of manufacturing particularly stable low- density foam. The expanded beads, after they are restored to atmospheric pressure are discharged to a storage facility and maintained at an elevated temperature for immediate use in a molding apparatus. The expanded hot beads may be fed directly by air injection conveyors to mold cavities and molded into the desired articles. Apparatus comprising heating, mould and transfer means is disclosed and illustrated.

Patent GB-2045183-A (GB)
Title: Silencing and cooling vehicle engines
IPC: B60R13/08
Filed: 1980-03-06
Abstract: A construction equipment motor vehicle, such as dump truck, tractor shovel or motor grader, has a cooling system for the engine 1 which includes a radiator 2 and a mixed flow fan 3. The fan 3 is located in a compartment 6 separated from the engine compartment, so that the air drawn through the radiator by the fan can be discharged directly to the atmosphere rather than through the engine compartment. This arrangement, together with the fact that the fan is a mixed flow fan (itself quieter than an axial or radial fan of corresponding throughput), enables a reduction in noise from the vehicle to be achieved. The air discharge from the fan compartment 6 is upwards, and the exhaust fumes from the pipe 12 are diluted in this flow. <IMAGE>
