Abstract: ABSTRACT OF THE DISCLOSURE           Flame-retardant antistatic polymer additives are provided which inhibit the buildup of electrostatic charges upon the addition of such compositions to synthetic polymeric fibers, i.e., polyamide fibers, and at the same time do not contribute to the flammability characteristics of such polymeric fibers.  The flame-retardant antistatic polymer compositions are useful in combinations with fibers such as polyamide, poly-ester, polyurea, polyurethane, polysulfonamide, polyolefin and polyacrylic fibers.  The antistatic effect is obtained by the process of coating the fibers or dispersing in or on the fibers up to about 12 percent by weight of a polymer composition which is the reaction product of :       (a)  a conjugated polyoxyalkylene compound or polyester thereof and (b)  at least one reactant selected from the group consisting of (1) a diol, (2) a polyester and (3) an aliphatic or aromatic diacid or derivative of (3), wherein said at least one reactant is halogenated and excludes tetrachlorophthalic anhydride. Improved flame-retardant properties can be obtained by including with the flame-retardant, antistatic polymer composition an effective flame retardant proportion of a compound from group Vb of the periodic table.  Generally about 1:4 to about 4:1 parts halogen to antimony compound is used.  Such compounds are oxides of metals such as phosphorus, arsenic, antimony or bismuth with the preferred compound being and mony trioxide.

Title: Process for preparing lubricating oil from used waste  lubricating oil
Inventor: WHISMAN MARVIN L
IPC: C10G67/04
Filed: 1978-03-20
Granted: 1981-04-28
Abstract: ABSTRACT OF THE DISCLOSURE      A re-refining process is described by which high-quality finished lubricating oils are prepared from used waste lubri-cating and crankcase oils.  The used oils are stripped of water and low-boiling contaminants by vacuum distillation and then dissolved in a solvent of 1-butanol, 2-propanol and methylethyl ketone, which precipitates a sludge containing most of the solid and liquid contaminants, unspent additves, and oxidation products present in the used oil.  After sepa-rating the purified oil-solvent mixture from the sludge and recovering the solvent for recycling, the purified oil is preferably fractional vacuum-distilled, forming lubricating oil distillate fractions which are then decolorized and deodorized to prepare blending stocks.  The blending stocks are blended to obtain a lubricating oil base of appropriate viscosity before being mixed with an appropriate additive package to form the finished lubricating oil product.  Advan-tages of the process include recovery of a higher percentage of waste oil, the formation of a by-product sludge that is essentially neutral and thus more environmentally compatible than are the sludges resulting from most other recovery pro-cesses, and reduced destruction of the diaromatic and poly-aromatic polar materials which impart natural lubricity and oxidation resistance to the oils.

Abstract: ABSTRACT     A method and apparatus for mounting a propeller on a tailshaft.   The propeller is arranged on the tailshaft so that a bore in the propeller or a metallic sleeve fixed in the propeller, which tapers towards the rear of the propeller, engages a complementary tapered portion on the tailshaft.   A tyre is arranged around the tailshaft in an annular recess in the rear face of the propeller so that the tyre is constrained radially.    The forward face of the tyre engages the propeller or a metallic sleeve fixed within the propeller and the rear face of the tyre engages an annular abutment member arranged around the tailshaft.   The annular abutment member is constrained against movement towards the rear of the tailshaft by a split shear-ring in an annular groove in the tailshaft to the rear of the annular abutment member.  Fluid is pumped into the tyre whereby it expands and urges the propeller and annular abutment member apart, thereby pushing the propeller along the tailshaft and developing a friction grip between the tapered bore in the propeller or in a metallic sleeve within the propeller and the tapered portion of the tailshaft.

Abstract: ABSTRACT OF THE DISCLOSURE           A gasoline dispensing nozzle which includes vapor recovery means and is magnetically held in place to the fueling filler neck of the vehicle, while at the same time providing for a tight seal at the nozzle filler neck interface.  This permits the recovery of gasoline vapors issuing from the vehicle fuel tank during the refueling process.          At the filler end of the nozzle there is a switchable permanent magnet to latch, support and hold the nozzle to the vehicle fillpipe.  When turned on, the magnet will direct its magnetic flux through the object to which the nozzle is held, that is, the filler neck surface with which the nozzle is in contact. To remove the nozzle when refueling is com-pleted, the magnetic flux is switched in a different direction to a metal element known as a keeper.  This releases the magnetic force of attrac-tion and unlocks the nozzle, thus permitting its removal from the fill-pipe.  The switching can be accomplished either electrically or mechanical ly.  A pressure sensing mechanism is provided at the outer face of the magnet so that when a suitable seal is made between the nozzle magnet and the filler neck surface, a signal is provided via the pressure sensor that the seal has been made.  Then the fuel valve may be opened on demand or automatically closed when there is a loss of pressure signal (i.e., the seal is broken), whereupon flow is not permitted.  The nozzle is designed to have a forward portion which is swiveled or pivoted about an axis on the rear portion of the nozzle. This forward portion or torque arm is relatively short in length and provides a minimum amount of moment arm with respect to the axis so that minimum peel forces are generated by the weight of nozzle and hoses which permits smaller size magnets to be utilized.

Abstract: DIRECT CURRENT BALLASTING AND STARTING CIRCUITRY FOR GASEOUS DISCHARGE LAMPS               Abstract of the Disclosure Direct current ballasting and starting circuitry for efficiently operating a gaseous discharge lamp on direct current.          Series-pass switching means in one of a pair of input lines alternatively switches between on and off states to periodically supply pulses of energy from a source of direct current voltage.          During steady-state operation, current sensing means limits the maximum current conductable by said switching means such that the output of the circuitry is current regulated.  Filter means, in series with the switching means, smoothes the pulses of energy delivered by the switching means into direct current with a com-paratively  small alternating current component.  Starting means, in series connection between the filter means and an output termin-al, senses the nonionized state of the lamp and provides a voltage pulse of sufficient magnitude and duration to initiate ionization in the lamp.  The starting means permits uninterferred passage of current from the filter means to the output terminal.  Various forms of control means or drive means for controlling the con-ductive state of the switching means are disclosed, including a phase-corrected oscillator which is momentarily excited by a starting pulse delivered at the output terminal and oscillation is thereafter sustained by interaction with the switching means; a resonant transformer capacitor circuit with a secondary winding of the transformer controlling the conductive state of the switch ing means; and a pulse width modulation drive means.  Operation of the circuitry in a current-limited output mode is accomplished by either sensing current delivered by the switching means or by sensing the current level through a commutating diode.     various starting means are disclosed, including one embodiment in which a single starting means senses the nonionized state of one of a plurality of lamps, with each lamp operating from a separate ballasting circuit, and provides a starting pulse for the nonionized lamp.         An A.C. to D.C. power conversion circuit, for opera-ting a plurality of ballasting and starting circuits therefrom, utilizes a portion of a primary winding of a transformer for connection to the A.C. voltage source.  A stepped up A.C. voltage across the entire primary winding is applied to a rectification means, which rectifies the A.C. voltage and supplies the same to a filter means.  The filter means provides a D.C. voltage for input to the ballasting and starting circuits.  A center-tap on a secondary winding of the transformer is referenced to the second of a pair of input lines of the ballasting and starting circuit, and the ends of the secondary winding provide a small A.C. voltage to the cathodic heater element of the lamp.
