Abstract: A method for simultaneously carbonating and cooling a liquid beverage. The apparatus used for the method includes an upright enclosed vessel with an upright coaxial carbonating column within the same and spaced therefrom to define an upright channel. A source of liquid to be carbonated and liquid carbon dioxide are directed into the lower end of the carbonating column and the product overflows the carbonating column into the annular channel wherein it passes downwardly and out of the vessel. A bypass line of ambient liquid is sprayed onto the top of the carbonating column to dissolve floating ice crystals. Also, a screen is placed between the carbonating column and annular channel to prevent passage of such ice crystals.

Abstract: In accordance with the present invention, there is provided an improved hook for use on an electrical appliance such as an upright vacuum cleaner or floor polisher, around which may be wound or looped the electric cord for storing the latter when the appliance is not in use, but which may be moved so as to quickly release all turns but one of the cord.

Abstract: In accordance with the present invention, there is provided an improved arrangement for and method of electrically testing a cord-set during the molding of the male plug and female receptacle to the opposite ends of the insulated electric cord. In order to accomplish this, the mold for forming the molded plug and receptacle is provided with suitable contacts which upon the closing of the mold automatically establish electrical connections between the terminals of the cord-set and circuits in testing apparatus. These tests consist of checking for continuity in each conductor and for shorts between conductors or terminals and a skin ground test for the purpose of detecting stray strands of wire or any current carrying object that would carry current to the outside surface of the molded plug or receptacle.

Abstract: In accordance with the present invention, there is provided control means in a vacuum cleaner for automatically maintaining a substantially constant volumetric air flow within the limits of the capabilities of the system, under varying conditions of resistance to flow occurring any place in the line of flow from the suction nozzle to the inlet to the fan. A further feature is the provision, as part of the control means, of an electric circuit which may be employed also to start and stop, by means of a switch on the hose handle, both the main fan motor and a motor for driving a brush in the nozzle.

Abstract: A fruit-flavored quiescently frozen confection is produced which is high in total fruit solids content and which has increased resistance to melting and increased protection against stickiness in storage. The high concentration of fruit is obtained by using pureed fruit.

Abstract: In accordance with the present invention there is provided a molded commutator having an improved form of anchoring tooth for each bar extending substantially the entire length of the bar for securing the latter to the molded hub. The invention involves an improved process of forming each anchoring tooth without the removal of any material and hence without wastage.

Abstract: Cocoa flavored syrups having a high cocoa content and excellent stability and flow properties at room temperature may be produced by using an amylolytic enzyme and a sufficient proportion of Dutch process cocoa to provide a syrup pH of 5.5 to 7.5. The syrup is made by alternate addition of cocoa and sweetener to sufficient water to achieve a solids content of about 58 to 65 weight percent, adding an amylolytic enzyme, heating to a temperature of about 175.degree. to 185.degree. F. for at least 10 to 15 minutes, raising the temperature to about 200.degree. F. and cooling. The stabilized cocoa flavored syrups may be added at room temperature to conventional non-acid confection mixes for use in the production of quiescently frozen chocolate flavored confections.

Abstract: A frozen confection which is comprised of a plurality of ingredients of individual colors. In some portions of the frozen confection the colors of the various ingredients are discrete and are readily identifiable. In other portions of the frozen confection the ingredients intermingle and thereby form colors which are different from the colors of the initial ingredients. Additionally, a gravity feed arrangement for feeding a plurality of nozzles with ingredients disclosed. Finally, a particular nozzle having a plurality of inlet conduits and one discharge opening for forming the frozen confection is disclosed.

Abstract: A hollow drapery rod having a decorative face at the top, front and bottom, a trackway at the rear side, and a pulley housing inwardly of the end of the rod. The rod has bracket receiving openings in the top and bottom adjacent the pulley housing and the rod support bracket has a U-shaped saddle with one leg underlying the bottom of the rod and an upwardly extending leg extending through the bracket receiving opening of the bottom of the rod and through the rod and out through the bracket receiving opening in the top of the rod to firmly support and position the rod. The pulley housing has wall portions engaged by the upwardly extending leg on the support bracket to be anchored thereby and the wall portions of the pulley housing aid in guiding the upwardly extending leg on the bracket through the rod and out of the bracket receiving opening in the top of the rod to facilitate installation of the rod on the bracket.

Abstract: A traverse rod including a downwardly opening carrier channel having inwardly extending carrier support rails at its lower edge, a master carrier mounted on the rod for movement parallel to the carrier channel and having master drapery support means thereon, and an intermediate carrier system, including a lead carrier at the end of a flexible string and a plurality of auxiliary carriers at spaced locations along the string each having heads guidably mounted on the rails at the lower end of the channel. The master carrier is constructed and arranged with relation to the rails at the lower edge of the channel so that the lead carrier on the intermediate carrier system can slide along the rails to a preselected position relative to the master drapery support means on the master carrier, and clamp means are provided to engage the lead carrier and master carrier to detachably secure the lead carrier in said preselected position to the master carrier.

Abstract: In accordance with the present invention there is provided improved winding retention means for the field coils in the stator of a rotary electric machine, particularly for coils which are wound in place on the field core by an automatic winding machine. As is well known, winding guides are temporarily secured at each axial end of the stator poles. The shuttles of the winding machine wind successive turns of wire around the poles and in the space between the latter and the winding guides. The retention means includes insulated flat steel wire or strips which .[.are secured to the core as by extending.]. .Iadd.extend .Iaddend.through passages or slots formed in the core laminations. These strips extend out from .[.opposite ends of.]. the core .[.and.]. .Iadd.in both directions and are bent to form off-sets which bear against opposite ends of the core to prevent longitudinal displacement of the strips in the apertures. The end portions of the strips beyond the off-sets extend .Iaddend.
