Title: Means for detecting a loss of vacuum in vacuum-type circuit interrupters used in polyphase a.c. vacuum circuit breaker
IPC: H02H3/08
Filed: 1977-10-27
Abstract: This loss-of-vacuum detecting means for a vacuum circuit breaker utilizes input information derived from the current transformers of the overcurrent-sensing means typically present in medium voltage switchgear. In this overcurrent-sensing means, the current transformer secondaries for the respective phases of the switchgear are connected in parallel with each other across a shorting conductor and in series with each secondary is the operating coil of an overcurrent relay. Connected in the shorting conductor is an "a" switch that is closed when the vacuum circuit breaker is closed and is opened when the circuit breaker is opened. Rectifying means is connected across said switch for developing a d.c. voltage when said switch is opened and one or more of said secondary windings is energized. Time-delay relay means is arranged to be energized by said d.c. voltage and is operable when the voltage thereacross exceeds a predetermined level for a predetermined minimum period following opening of said switch. Operation of said relay means is indicative of a loss of vacuum in one of the vacuum interrupters of the vacuum circuit breaker.
Patent ES-464578-A1 (ES)
Title: Loading device for goods vehicles
IPC: B60P1/44
Filed: 1977-11-29
Abstract: A loading device for a goods vehicle comprises a lifting platform which can be raised to the height of the loading surface and then pivoted into a vertical position to form a tail gate. The rear end of the lifting platform can also be tilted downwardly when the lifting platform is at road level or a loading surface height. The lifting platform is supported and operated by two hydraulic rams in conjunction with two lifting arms and two guiding arms. The rams are hingedly connected with the lifting platform differently so that both serve to raise the platform and one serves to pivot the platform to vertical position after the platform has reached loading surface height. The cylinders of the two rams are commonly connected to a liquid reservoir through a valve-controlled return line containing a resistance so that pressure in the two cylinders is equalized and the different load moments resulting from the different hinge connections of the two rams causes the platform to swing down from a vertical position to a horizontal position before it is lowered. The guiding arms may consist of telescopic arms or hydraulic rams.

Title: Suspension polymerization process for making vinyl resins for use in plastisols.
IPC: C08F14/06
Filed: 1980-10-14
Abstract: This invention relates to the suspension polymerization of vinyl halides and vinylidene halides in an aqueous medium to make polymers and copolymers which are designed for use in making plastisols. The process is conducted in an aqueous medium using a free-radical yielding catalyst, and in the presence of a hydrolyzed polyvinyl acetate (polyvinyl alcohol) having a degree of hydrolysis in the range of about 65% to about 85% and a compound having a hydrophile-lipophile balance (HLB) less than about 3.5.

The suspension resins so produced are easily and uniformly mixed with a plasticizer to form plastisols which are stable, containing particles of uniform and proper size, and capable of producing films, and like products, of good clarity.
Patent ES-8201901-A1 (ES)
Title: Control device for electric motor vehicle
IPC: B60L3/00
Filed: 1980-11-12
Abstract: PURPOSE:To enhance the reliability of an electric motor vehicle by switching a normal operation command position to an emergency operation command position when the constant current control system in normal operation malfunctions, and controlling directly a phase shifter for a chopper by operating a current flow rate controller. CONSTITUTION:When the constant current control system CC malfunctions while the electric motor vehicle is operated with the control system CC by a normal operation command MMC, a main controller SH is switched to the position of an emergency operation command EMC, thereby operating the current flow rate controller CRC. When the controller CRC is operated, the current flow rates of the choppers CH1, CH2 are continuously controlled by the input voltage to the phase shifters PS1, PS2. Thus, an emergency operation can be conducted even when the normal operation function is failed.
