Title: Process for the recovery of metals from oxidic ores
Inventor: DANIELS MICHEL
IPC: C22B15/00
Filed: 2020-07-27
Abstract: A process is disclosed for the recovery of valuable metals from oxidic ores, in particular from polymetallic nodules. The process is suitable for the recovery of Cu, Co, Ni, Fe, and Mn, which are the main metals of interest in such polymetallic nodules. Present process is, among others, characterized by the handling of Fe, which is dissolved and kept in solution until the step of crystallization rather than removed at an earlier stage. Mixed Mn-Fe residue is obtained, which, after thermal treatment, provides Mn-Fe oxide that is suitable for the steel or for manganese industry. Excellent Cu, Co and Ni yields are obtained, while Fe is leached and valorized together with Mn.  	  s Table: 	6

Title: Modified c-shaped mechanical spring seal
Inventor: JANIAN ROBERT
IPC: F16J15/12
Filed: 1985-01-28
Granted: 1993-11-09
Abstract: A mechanical spring seal is provided comprising in combination an elastomeric jacket and a resilient spring insert, both having a generally C-shaped cross-sectional configuration. The major portion of the length of the spring follows a relatively shallow curvature between the base and a position along the cross section at which the spring is widest, forming a pair of opposed cantilever arms which provide the major sealing force. From this region of greatest width to the tips of the spring, the curvature is substantially sharper, enabling the end of the spring to fit in fixed locked position within the jacket which conforms to it. At the base of the C-shaped spring, the curvature is also sharper than it is in the long cantilever arm portions. The spring receiving interior concavity in the jacket is complementary in nature to the shape of the spring, and has an open side for insertion of the spring into the jacket, the inwardly angled tips of the spring preventing its release from the jacket.

Abstract: Title:   IMPROVED FUEL COMPOSITIONS                   ABSTRACT OF THE DISCLOSURE Fuel   compositions   for   internal  combustion engines,  and  more  particularly,  fuel compositions for use  in  fuel-injected  internal  combustion  engines are described.    The  fuel  compositions  comprise  a  major amount   of  a  liquid  hydrocarbon  fuel  and  a  minor, property-improving   amount   of   a  hydrocarbon-soluble dispersant  prepared generally by the post-treatment of a nitrogen-containing    composition    with    mono-   and polycarboxylic  acids  which may be aliphatic or aromatic carboxylic  acids  although aromatic polycarboxylic acids are  preferred.    The  nitrogen-containing compositions which  are  post-treated  in  accordance with the present invention  are  obtained  by  reacting an acylating agent with  alkylene  polyamines  or alkanol amines.  When fuel compositions  of  the  present  invention are utilized in internal  combustion  engines,  and  in particular, fuel-injected  internal  combustion  engines,  the  amount  of solid  deposits  of  the  various  parts  of the internal combustion  engines  are reduced.  In particular, the use of  such fuels prevents or reduces intake system deposits and  injector  nozzle deposits.  Accordingly, methods for reducing  or  preventing  the  build-up  of  deposits  in internal combustion engines also are described.

Title: Phase-locked loop
Inventor: SATO HIDEO
IPC: H03L7/091
Filed: 1987-02-24
Granted: 1991-04-02
Abstract: ABSTRACT OF THE DISCLOSURE          A PLL comprising a phase comparator circuit for detecting the phase of a pulse signal based upon the input signal and the phase of a pulse signal based upon the output signal, a smoothing filter for smoothing the output of the phase comparator circuit, a loop filter for controlling the oscillation frequency on the basis of the smoothing filter, and a voltage controlled oscillator circuit for sending out the output signal having a frequency corresponding to the voltage based upon the output of the loop filter.  Since the smoothing filter is separated from the loop filter, time constants of the smoothing filter and the loop filter can be set inde-pendently and with precision.  If the time constant of the smoothing filter is chosen to be extremely small, for example, the time constant of the phase-locked loop is defined by the time constant of the loop filter.          It is thus possible to define the time constant of the phase-locked loop by only selecting the time constant of the loop filter.  And it is possible to suppress the jitter of the phase-locked loop and reduce the frequency ripple, for example.

Abstract: Abstract of the Disclosure Treatment of fiber-reinforced plastics (FRP) surfaces for brief periods of time to exposure to short wavelength (not more than 270 nm) ultraviolet light in air, (i.e., UV/Ozone), removes loosely-bound low molecular organic material and oxidizes the surfaces and hence increases the adhesive potential of FRPs to polyurethane adhesives. Furthermore, FRP polymer surfaces treated by this process retain more adhesive strength after aging at elevated temperature in the presence of moisture than untreated surfaces or surfaces washed with isocyanate in methylene chloride.  Epoxy adhesives, also can be used.
