Abstract: ABSTRACT OF THE DISCLOSURE A toy in which so-called "ball people" -- figurines which are capable of rolling along an inclined surface -- are transferred from one location to another in such a way as to amuse a child can be constructed so as to include a composite of several transfer mechanisms serving as a unitary transfer mechanism.  The disclosed toy includes a more or less tubular tower which extends upwardly from a base.  A threaded shaft extends upwardly through the tower.  A carrier is located within the tower and is mounted in such a way that as the shaft is rotated the carrier is capable of lifting a figurine from adjacent to a lower or receiving opening to an upper or discharge opening. An inclined chute is provided on the tower so as to receive such a figurine and transport it to a pickup location.  An arm mounted upon the upper end of the shaft carries a holder which is rotatable with respect to the tower.  When the holder is  opposite the pickup location a figurine at the pickup location is taken onto the holder and is rotated to another location where a trap door in the bottom of the holder is opened so that the figurine can be deposited on a runway from which it can be transported away from the transfer mechanism.

Abstract: ABSTRACT OF THE DISCLOSURE The invention relates to a scale for weighing bulk goods.  A first scale first measures the weight of the bulk goods.  A digital computing device, responsive to the scale, includes a digital display coupled to the device for res-pectively computing and displaying a weight measurement, the weight measurement being the determined mean weight of the bulk goods over a measuring cycle.  The scale further includes a reference oscillator and a counter for counting the oscillators of the reference oscillator to one end of two alternatively selectable end values for establishing two alternatively selectable measuring cycles.  A first memory stores the weight measurement of a measuring cycle, and a second memory stores a weight measurement of an immediately preceding measuring cycle.  A difference circuit computes a difference between the weight measurements stored in the first and second memories and forms a difference signal. A comparison circuit, which is responsive to the difference signal, formulates a control signal indicating whether the difference is greater than or less than a threshold value. A controller, responsive to the control signal, controls the scale so that when the difference is greater than or equal to the threshold, a short measuring cycle is selected as a following measuring cycle.  When the difference is smaller than the threshold value, a long measuring cycle is selected as the following measuring cycle.

Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus and method for sensing and controlling the concentration of toner in a developer mix comprising toner and carrier particles used to develop electrostatic images on a photoconductive or the like member includes the provision of a surface which is electrically insulated from the toner and carrier housing and is triboelectrical-ly dissimilar from the developer mix.  The developer mix is flowed over the surface and a corresponding direct current voltage is generated triboelectrically due to the interaction thereof.  The direct current voltage is connected through resistance to the housing and the direct current flowing through the resistance is related to the concentration of toner in the developer mix.  Apparatus responsive to a predetermined value of voltage generated is employed to control the replenishment of toner to the the developer mix.

Abstract: ABSTRACT OF THE DISCLOSURE          A damper assembly including a plurality of damper blades pivotable about parallel axes.  Each blade includes a pair of parallel plates spaced apart by supporting members, the plates providing a substantially unrestricted open fluid passageway through the blade.  When the damper blades are in the closed condition, the passageways form a single enclosed space into which pressurized sealing air may be introduced to render the damper gastight with respect to gases in the main duct.  In the open condition the damper blades offer very little flow resistance by allowing conduit gases to flow through the passageways between the plates of the blades.

Abstract: Abstract of the Disclosure An injection shuttle system is disclosed for fabricating stator core assemblies.  Injection tooling and a stator core are selected and positioned on a shuttle means at a selection station for moving to coil loading stations and a transfer station.  The injection tooling is positioned, aligned and manipulated relative to a winding machine at each coil loading station for disposing winding turns thereon.  At the transfer station, the injection tooling is transferred to a wedge guide housing of a turntable arrangement which includes wedge making and injection stations.  A stator height adjustment arrangement is provided for adjusting the wedge making and injection stations in accordance with the axial length of the core.  The injection tooling is moved or indexed to the wedge making stations where insulating wedges are fabricated and inserted into wedge guides of the wedge guide housing.  The injection tooling is then moved to the injection station where the core is interfitted with the tooling by a core transfer assembly.  An injection mechanism at the injection station then injects or transfers the winding turns and insulating wedges into axially extending slots of the core.  The end turns of the windings are then moved away from the bore of the core by an end turn separator.  The injection tooling with winding turns removed therefrom is indexed or moved to an unloading station where it is transferred from the turntable arrangement to a shuttle means for subsequent transfer back to the selection station.

Abstract: ABSTRACT OF THE DISCLOSURE     Disclosed is an interlocking mechanism for a switched socket outlet having a manually-actuatable switch and a socket for accepting a plug having an external key.  The mechanism has an interlock member displaceable by operation of the switch between a switch-open position and a switch-closed position, and a pin movable by the key upon insertion of the plug into the socket.  In the switch-open position, the interlock member allows the plug to be inserted and move the pin from an extended position wherein it prevents attempted closure of the switch by obstructing displacement of the interlock member to the switch-closed position, to a retracted position in which the pin allows such movement of the interlock member.  The interlock member may be so arranged as, when in the switch-closed position, to obstruct the return path of the key to prevent attempted withdrawal of the plug from the socket while the latter is electrified.  The key on the plug also prevents the displacement of the interlock member from the switch-open position until the plug is fully inserted in the outlet.

Abstract: PHENOLIC RESIN RECOVERY PROCESS  ABSTRACT OF THE DISCLOSURE         A method of recovering a resin material from an infusible phanolic plastic composition.  The infusible phenolic plastic composition is ground to a powder and mixed with an alkali solution to produce a liquid mixture.  The liquid mixture is heated to a temperature selected between 260-340°C and maintained at this temperature between 160 and 3 minutes causing the resin in the infusible phenolic plastic composition to dissolve in the alkali solution and produce a liquor.  Thereafter the liquor is passed through a filter to remove any insoluble plastic composition therefrom.  An acid solution when added to the filtered liquor causes a solid to precipitate from the liquor.  The solid is separated from the liquor and washed in a water bath to remove any water soluble salts, phenols, and cresols from the recovered resin material.
