The solid rotor and shaft includes a central rotor portion having a substantially larger diameter than the opposing shaft portions extending from either end of the rotor portion. Conductor bar passages are formed adjacent the outer circumferential surface of the rotor portion to accept the respective number of conductor bars making up the secondary winding in the solid rotor and shaft.

Abstract: An abrasive tool includes in combination a tubular sleeve of exteriorly coated abrasive which has an axial length and an inside diameter. A drive arbor for the sleeve includes a mandrel adapted to be rotated by a power tool and the like. An elastomeric generally cylindrical arbor is mounted on one end of the mandrel and has an outer and inner axial end. The arbor includes a radially projecting stop flange at its inner end and has a tapered configuration between the stop flange and its outer end to receive the abrasive tubular section, but which creates an interference fit as the tubular section is telescoped on the arbor until one axial end of the tubular section engages the stop flange. The arbor body is provided with non-radial slots which make the body more pliable in a static condition, but which improve the grip of the arbor on the sleeve at speed. The slots also improve heat dissipation.

Abstract: Confections produced from flavor powders obtained from powdered roasted syrup of dahlia tubers. These dahlia flavored powders can be used to replace cocoa powder. When milled with a confectioner fat, the dahlia flavored powders produce a confection similar to chocolate. The powders can also be blended with protein, milk solids, fiber, carbohydrates such as starches, bland flours and sugars to produce flavor mixes which may be used as a direct replacement for cocoa powder and which can be ground with cocoa butter or a confection fat to produce chocolate-like confections. Foods incorporating these confections such as beverages, baked goods, desserts, icings, coatings, candies, syrups or ice cream are similar to analogous products made with natural cocoa or chocolate.

Abstract: A high speed spindle preferably of the motorized type is described having means for axially preloading the spindle bearings and hydraulic preload locking means for locking the preload against diminution by expected axial pull-out forces exerted on the spindle shaft counter to the preload during machining. The hydraulic locking action is released in the event unexpectedly high, potentially damaging axial pull-out forces are encountered during machining.

Abstract: A digital phase-locked loop consisting of a digital phase detector for detecting the phase differences between the output and the input frequency signals, a microprocessor programmed to perform both the functions of the loop filter and the phase shifter, and a binary rate multiplier to perform the function of voltage-to-frequency conversion is disclosed. A more precise frequency resolution is obtained by use of the binary rate multiplier and a further reduction in circuit complexity is achieved by removal of the phase shifter circuit in favor of the microprocessor programming.

The resultant pregelatinized modified starch possesses a smoother, creamier mouthfeel and has a high sheen.

Abstract: A taffy-like confection is prepared from an admixture of a sugar melt having at least 40% fructose and a surface active agent. The confection contains granulated gasified candy suspended therein.

Abstract: A process for making a fructose polymer mixture containing chiefly inulin and inulides with minor amounts of impurities is based on the finding that inulin is in a soluble metastable state at room temperature as it exists in the dahlia tuber. Novel steps in the process are the separation, without the use of heat or adding water, of the water soluble from the ground dahlia tuber within about 10 minutes after grinding, followed by separation by coagulation of protein color and flavor bodies by heating at the boiling temperature from 3 to 10 minutes. No chemical defecating agent, such as lime water is used or required. The resulting clear extract is concentrated to 40% to 70% solids. Dry product is recovered by crystallizing the concentrated extract at 1.degree. to 15.degree. C. The product differs from inulin in that the product, in addition to inulin, also contains inulides, protein, color, flavor bodies, and minerals.

Abstract: This invention concerns the extraction of the water solubles of the dahlia tuber which contains aroma and flavor bodies and the concentration, drying, and roasting of these extracts to produce additional flavor bodies. The roasted and ground flavorsome beverage powders so produced can be used to make palatable beverages in hot or cold milk or water. Furthermore the above beverage powders can be blended in concentrations of 1 to 99% with the flavor powders of coffee, tea or cocoa to produce flavor powders that complement each other when used to make water or milk beverages. Another objective is to blend the dahlia flavor powders with sugar or sugar mixtures to make sweetened beverage powders. Such sweetened beverage powders can again be blended with the powders of coffee, tea or cocoa.
