Title: Surface treated steel sheet for welded can material and method for its production
Inventor: KAWAMURA HIROAKI
IPC: C25D11/38
Filed: 1986-02-28
Granted: 1991-02-12
Abstract: ABSTRACT OF THE DISCLOSURE      A surface treated steel sheet having double layers consisting of a lower layer of metallic chromium and an upper layer of hydrated chromium oxide are formed on a low tin plated steel sheet in which 30 to 80% of the surface of the steel sheet is covered with plated tin and the size of the exposed steel surface units, after tinplating, is 0.5 to 20 µm in diameter when expressing the irregularly exposed areas as circles, and a method for production of this surface treated steel sheet which comprises; (a) electro-plating with a small amount of tin under restricted condi-tions in order to obtain the low tin plated steel sheet described above, (b) after reflowing or without reflowing of the plated tin, formation of said double layer or formation of the metallic chromium layer followed by formation of hydrated chromium oxide under restricted conditions.     This surface treated steel sheet is suitable for producing a welded can body without removing the plated layer at high speed, since it is excellent in weldability, lacquer adhesion and corrosion resistance after lacquering.

Granted: 1992-07-07
Abstract: ABSTRACT    A compressor assembly including an electric motor and a compressor crankcase.  The compressor crankcase includes a suction inlet.  A motor casing is secured to the crankcase.  The suction inlet is connected by means of a first passage to the interior of the motor casing.  A baffle located in the motor casing causes a portion of the inflowing refrigerant suction gas to be diverted to flow over and cool the rear windings of the motor. The remainder of the inflowing gas is caused to flow over and cool the front windings of the motor.  After flowing over the windings, the two portions of the suction gas are recombined and the suction gas is then caused to flow out of the motor casing to the compressor cylinder suction inlet.

Abstract: DOUBLE-LOOP CORIOLIS TYPE MASS FLOWMETER         Inventor:  Peter J. Herzl, a citizen of the United States of America and resident of Morrisville, PA     ABSTRACT OF THE DISCLOSURE          A mass flowmeter of the Coriolis type in which the fluid to be metered is conducted through a pipe which is coiled to form a double loop.  The pipe is anchored at its inlet and outlet ends and also at its center which is the junction of the two loops to define a tuning fork in which the identical loops on either side of the anchored center function as tines that are free to vibrate as well as to twist.  An electromagnetic driver mounted at the vertex of the double loop is electrically energized to cause the loops to vibrate in phase opposition at the natural frequency of the tuning fork.  The fluid passing through the double loop is subjected to Coriolis forces, thereby causing the vibrating loops to torsionally oscillate in accord-ance with the mass flow of the fluid.  Capacitance sensors are symmetrically mounted on the respective loops to yield signals having a difference in magnitude and phase that depends on the amplitude of the torsional oscillations, these signals being applied to a differential amplifier whose output is proportional to the mass flow of the fluid.
