Abstract: A B S T R A C T     An artificial Christmas tree including a plurality of branch mounting members which are designed to support and laterally restrain branches for movement between a raised ship-ping position and a lowered display position.  In prior artificial trees difficulty has been experienced in attempting to provide adequate support and ease of mounting of the branch members.          According to one aspect of the present invention an artificial tree comprises an elongated trunk member, a plurality of branch members each having an eyelet at the inner end thereof, a plurality of branch mounting members and a branch mounting pin.  The branch mounting members are mounted at spaced intervals on the trunk and each consist of a sleeve member mounted on the trunk, a plurality of branch mounting wing sets on the sleeve, each wing set consist-ing of a pair of side walls projecting racially from the sleeve in a spaced parallel relationship to define a branch receiving passage therebetween.  The side walls are arranged sufficiently close to one another to provide a lateral support for the inner ends of the branches on opposite sides of the branch receiving passage.  A branch supporting transverse wall extends between the side walls and a branch mounting passage extends transversely through the side walls.  The branch mounting pin projects through the branch mounting passage and the eyelet of a  branch member to pivotally mount a branch member on each wing set for movement between an elevated position and a lowered position as aforesaid.

Abstract: PROCESS FOR ELECTROLESS PLATING   USING COLLOID SENSITIZATION          Abstract of the Disclosure A process is described for the electroless deposition of metals on nonmetallic surfaces.  The process involves pretreatment of the nonmetallic surface so as to obtain a surface finish suitable for deposition of colloidal sensitizers which catalyze electroless metallic deposition.          The nonmetallic surface is then exposed to a colloidal catalyst solution (typically SnCl2/PdCl2) followed by an acid rinse.  On completion of this surface activation procedure, the surface is exposed to a bath for the electroless deposition of metal.  This procedure, which differs from that traditionally used, insures more reliable catalyst for electroless deposition of metals with shorter initiation times and is simpler in procedure and lower in cost.     - i -

Abstract: ABSTRACT OF THE DISCLOSURE          A miniature valve for very small animals such as tiny weanling mice consisting briefly of a housing having an interior passage.  A lever arm extends through the passage and slightly beyond the end of the housing so that the animal can move the lever by biting it with its teeth or deflecting it with its tongue.  Deflection of the valve arms causes a valve head member to pivot and partially lift off a valve seat.  The valve seat is of resilient material and formed at an angle to the underside of the valve head so that a "line-point" type contact is made between the valve head member and the valve seat.         A biasing member, such as a spring, returns the lever arm to a centered position when the animal lets go of the lever thereby automatically preventing further water flow.

Abstract: ABSTRACT OF THE DISCLOSURE A recessed pill is provided for movable panels, e.g. the front panel of a file cabinet, desk drawer or the like in which the front panel has an aperture intermediate its sides. A unitary trim piece is provided for surrounding the aperture, having grooves along its upper and lower edges adapted to accommodate the upper and lower edges of the panel around the aperture. Yielding edge means are provided intermediately disposed integrally on the trim piece and comprising an intermediately extending beveled portion along at least one of the edges of the trim piece and defining the corresponding portion of the groove thereat for enabling the trim piece to be deformed locally thereat in a direction substantially crosswise of the normal plane of the beveled portion under pressure laterally there against and to return to its original shape upon the release of the pressure, whereby the trim piece may be pressed thereat against an adjacent edge portion of the panel around the aperture and into self-supporting position into the aperture with the upper and lower edges of the panel around the aperture accommodated in the grooves along the upper and lower edges of the trim piece upon the release of the pressure and return of the trim piece to its original shape for snap-locking the unitary trim piece into the panel aperture.  A cover member is provided having rear, top and bottom walls and a flange downwardly extending from the top wall of the cover member engageable in the groove along the upper edge of the trim piece.  Weight means are provided for exerting downward pressure on the flange of the cover member to maintain the flange in the groove in the trim piece to inhibit inadvertent disengagement of the cover member from the trim piece. By such construction, the possibilities of damage to the hand of the user or engagement with the clothing of a passerby who might come into inadvertent contact which relatively sharp edges are minimized.  Also, inadvertent buckling of the panel or drawer front under certain conditions is minimized.

Abstract: IMPROVEMENT IN WHEEL SLIP CONTROL SYSTEM ADAPTED TO USE ON LOW COEFFICIENT SURFACES         ABSTRACT OF THE DISCLOSURE    A wheel slip control system generates one level of brake relief when a fixed threshold of wheel deceleration is exceeded.          The system generates a second level of brake relief when a variable threshold, dependent upon both deceleration and velocity, is exceeded.          A fixed acceleration threshold circuit monitors wheel acceleration during brake relief.  Under normal road and load conditions, where wheel acceleration is great enough to exceed the fixed acceleration threshold, termination of brake relief is initiated by the increase in wheel velocity past a variable reference threshold which has a fixed part and a variable part.  The fixed part is an a priori prediction of the minimum vehicle velocity decrease under normal stopping conditions.  The variable part is dependent on wheel acceleration alone.     When the acceleration threshold is not exceeded, as with slippery roads or very light loads, termination of brake relief is delayed until wheel acceleration decreases to a low value.          This allows the wheel velocity to come up to approximately full vehicle speed before allowing brake re-application. A brief re-energization of the first level of brake relief, performed after a brief delay, reduces the tendency of the vehicle wheels to hop and bounce.

Abstract: ABSTRACT OF THE DISCLOSURE         A method is disclosed for breaking an oil-in-water emulsion.  Briefly, the method of this invention includes the following general steps.  A porous ferrous ion producing anode is established.  A supply of the oil-in-water emulsion is located on one side of the anode and a fixed volume of the emulsion is flowed through a fixed cross sectional area of the anode per unit of time.  Less than a passivating current is flowed through each unit area of the anode per unit of time thereby dissolving into the emulsion ferrous ion in sufficient quantity to break the emulsion.  The flowing of the fixed volume of the emul-sion through the electrode per unit of time and the dis-solving of sufficient quantity of ferrous ions results in a homogeneous dispersion of the ferrous ions in the fixed volume of the emulsion.  There is an in situ generation of hydroxyl ion at the cathode and tiny air bubbles are intro-duced near the electrodes to oxidize the ferrous ions to ferric ions.  The ferric ions are then permitted time to break the emulsion and remove the oil therefrom.  This oil floats to the top surface in a froth and is removed.
