Abstract: A B S T R A C T   The alumina linings of electrolytic reduction calls become contaminated with carbides, nitrides and fluorides with continued use of the cell.   A procedure for the recovery of such used alumina linings comprises subjecting the crushed used lining to the action of dry steam in a pressure vessel to effect break down and removal of carbides and nitrides. The thus treated material, which is partially hydrated, is then charged to the electrolyte of an electrolytic reduction cell to recycle both the fluoride and alumina content of the used alumina lining.

Abstract: ABSTRACT OF THE DISCLOSURE       In an activated sludge process for the treatment of liquid wastes, liquid from the main reaction vessel is circulated downwardly through one or more vertical columns. Bubbles of oxygen are introduced at the bottom of the columns to rise upwardly relative to the liquid flow.  A gas trap at the bottom of the last column collects small bubbles which are carried out of that column, and releases larger bubbles into the column.  Advantageously, an air lift may be used to carry liquid from the main reaction vessel to the columns, and this serves to strip unwanted carbon dioxide from the liquid.

Abstract: ABSTRACT     A commutation circuit for an inverter has a capacitor which is charged prior to commutation of the inverter from an auxiliary dc power source instead of by the principal dc power supply for the inverter.  Polarity of the voltage on the capacitor is reversed prior to start of commutation by a switch that connects a first inductor across the capacitor to establish a first capacitor current path through the first inductor.  No portion of the first capacitor current by which the capacitor achieves its reverse polarity flows through the inverter.  After the polarity of voltage on the capacitor has been reversed the capacitor is connected by switching so as to apply reverse polarity voltage to the dc input busses of the inverter.  Commutation current then flows through the inverter, but not through the first inductor.  A separate inductor is provided for the commutation current, in series with the capacitor and the inverter.  The circuit is partic-ularly advantageous for apparatus in which the principal dc power supply provides an adjustable dc voltage, because the energy available from this circuit for commutation is not significantly diminished by adjustment of the principal dc power supply to low voltage levels because the auxiliary dc power supply becomes effective at the low levels.

Abstract: ABSTRACT OF THE DISCLOSURE      Leakage of oil from a rotatable assembly is reduced by an arrangement comprising a shaft rotatably supported by a bearing assembly located within a housing. The housing includes a cavity surrounding a portion of the shaft and extending between the bearing assembly and an end wall of the housing through which the shaft extends.  A flinger is mounted on the portion of the shaft surrounded by the cavity for rotation therewith, and an oil deflector is located in the cavity .   Fluid flow within the housing caused by equalistion of pressure between the interior and the exterior of the housing causing leakage of oil takes place around the periphery of the oil deflector (i.e  in that part of the cavity occupied by air and oil foam) rather than between the shaft and the deflector where liquid oil may be lodged when such fluid flow is directed towards the exterior of the housing.  Oil passing the deflector tends to catch in the channel and be directed back to the sump.  Any oil passing the channel tends to be thrown by the flinger outwards and away from the point where the shaft passes out of the cavity.   7.

Abstract: ELECTRICAL CONNECTOR            ABSTRACT An electrical connector that is capable of being quickly coupled and decoupled.  The coupling and decoupling is accomplished by a coupling nut having a triple start thread (310) that allows .3 inches of axial movement for 360° of rotation of the coupling nut when the coupling nut is mated to the threads of a connector shell.  The triple threads (311, 312, 313) also minimize radial and axial deflection between a coupling nut (300) and a connector shell (200) and between the male and female electrical contacts (270, 370), when the two halves of the connector assembly are connected together.  This minimizes wear of the engaging surfaces and increases the life of the conductor.

Abstract: ABSTRACT OF THE DISCLOSURE         A keyable control circuit, has sensing coils located in the vicinity of a plurality of locations where lock control is desired.  At least one swept high-frequency oscillator, which is connected to each sensing coil, generates an rf signal, rapidly swept over a wide frequency band.  When an external keying circuit, containing more than one resonant circuit, each correctly tuned to a predetermined keying frequency, is induct-ively coupled to a sensing coil, each resonant circuit absorbs rf energy as the oscillator frequency is swept past its resonant frequency.  Electrical interaction between the resonant circuits is accomplished by reactive cancellation.  Energy absorption in the external keying circuit induce corresponding reductions in rf energy in the sensing coil as the oscillator frequency is swept past the keying frequencies.  Tuned detectors within the keyable control circuit produce a control signal when energy reduction is sensed at each of the predetermined keying fre-quencies.  If correct absorption fails to occur at any one or more of the predetermined frequencies, the control signal is withheld.          A time-gating  system enables selective direction of the control signal to one or more using locations while ex-cluding others.  This function finds convenient application in automotive use where it is frequently desired to enable simul-taneous unlocking of one or more doors while excluding unlocking of the deck lid.    A dead-oscillator detector averts attempted actuation of the unlocking function by the coupling of untuned energy-absorbing material, such as iron, to a sensing coil.

Abstract: ABSTRACT OF THE DISCLOSURE        An improved decorative display assembly having the aspect of a three dimensional sculpture is provided.  In this regard, a frame may be provided to which a first series of display sheets are separately connected in spaced relation. The sheets may be, for example, photos, prints, fluorescent cards or other sheets bearing decorative indicia on one side thereof.      The prints have been made self-supporting by attaching mounting boards to the indicia-free sides thereof.  These first sheets form a first structural level for the assembly. Spacers, preferably in the form of small blocks, are then fixedly of the prints, whereupon a second series of prints are connected adjacent their margins, and via their mounting board backings to the first sheets so as to only partially overlap the first sheets and thus form a second structural level to the sculpture.      Additional series of display sheets can be similarly connected to provide additional structural level, all to ultimately form the desired three dimensional multi-level sculpture montage effect of free form or predetermined shape. The end product is a highly decorative display.     The display sheets can be coated with clear plastic or the like to render them permanently protected, whereupon the finished individual sculpture assembly can be mounted on a table. wall or the like for display.      A kit may be provided containing the necessary materials for fabricating the assembly according to individual taste or according to patterns which can be included in the kit.  The kit may include, in addition to the previously described com-ponents, such items as temporary supports to align components before they are permanently fixed in place, color coded edge margins for the prints, etc.  The box in which the kit can be used as a support frame, if desired, for the assembly.  More-display means, such as screens,can be incorporated into the kit to facilitate fabrication of the desired decorative assembly.
