Title: Monitoring angular velocity of vehicles
IPC: G01C19/42
Filed: 1969-01-11
Abstract: In the control arrangement of the parent Specification, the input signal to the signalderiving means (which gives separate output signals for the angular velocity w and the angular acceleration w1 of the vehicle) is a gyro output signal, which varies with the angular velocity of the vehicle and the means has a comparator, for receiving the preferably amplified signal directly and another comparator fed through a CR differentiating means. As the vehicle runs through a curve, a positive voltage is provided in line 6 and a negative voltage in line 7. When the voltage in line 6 is increasing and exceeds the adjustable constant value E2, the output signals + w and + w1 are produced in the output lines 14, 23 of the comparators 10 and 16. When the voltage is still positive but decreasing and exceeds the value E2, the output signal + w1 is replaced by the output signal -w1 in output line 40 of comparator 34. On a curve in the opposite direction, line 7 becomes positive and produces signals -w in output line 31 of comparator 26 and -w1 in line 40.

Patent ES-469219-A1 (ES)
Title: Curing system for high voltage cross linked cables
IPC: B29C48/06
Filed: 1978-04-27
Abstract: This invention makes extruded, vulcanized, high voltage cables insulated with thermosetting compounds at much higher rates of production and with superior insulation of reduced thickness and with reduced cavities or voids in the insulation. As the cable comes from an extruder, it passes into a curing chamber with a heat booster that quickly raises the insulation to a temperature at which it is cured much more quickly than with steam heating of the prior art. A high temperature liquid in contact with the insulation maintains the high temperature and because of the greater curing heat, the cable can travel through the curing chamber at a faster rate and into a cooling tube where it contacts with a cooling liquid under high pressure. The insulation compound is treated to reduce the size of cavities and the high pressure maintained by the curing and cooling mediums prevent expansion of cavities before the insulation is set.
