IPC: C10N30/00
Filed: 1982-05-24
Abstract: PURPOSE:To provide a cold rolling oil for steel plate having excellent lubricating and anti-slip properties under high pressure and high speed conditions, prepared by adding polymethacrylic ester to natural fat or fatty oil or synthetic ester. CONSTITUTION:5-30wt% polymethacrylic ester with a molecular weight of 30,000-200,000 is added to natural fat of fatty oil or synthetic ester. When the molecular weight is lower than 30,000, the oil shown no improvement in lubricating property, while when it exceeds 200,000, the oil becomes difficultly soluble in base oil and difficult to handle, for its viscosity is increased to a considerable extent. When added in less than 5wt%, the polymethacrylic ester has only little effect of improving the lubricating property and when added in more than 30wt%, the lubricating effect is saturated and the oil becomes difficult to handle because of sharp increase in viscosity.

Abstract: PURPOSE: To prevent fire by such a construction that oscillation of a pendulum actuate a cock shutting piston to close automatically the main cock for gas when such large vibrations arise as causing crash of a house.  
     CONSTITUTION: When an oscillation wave comes from a certain direction, the whole apparatus oscillates driven by the wave while the weight of the pendulum 2 remains at a standstill owing to the inertia. The tip of pendulum oscillates more than the oscillation of the apparatus by an amount determined by the lever ratio of the pendulum. When the amplitude of the oscillation wave exceeds a certain level, the tip of piston 5 comes off the tip 3 of the pendulum, and the piston 5 is depressed by a spring 9. Then the arm 13 comes off from the major diameter part of piston 5 to release the lock, and the cock is turned to the close position with the action of a spring 12. Turning the arm 13 will not fix itself to the major diameter part of piston 5 unless the piston 5 is reset to its regular position.
