Abstract: A juice extractor is provided that includes an induction motor supported by a housing and having a rotatable shaft that is operably interconnected with comminuting basket adapted to pulverize food products, e.g., fruit and/or vegetables, into juice bearing pulp. The comminuting basket extracts the juice from the pulp and ejects the juiceless pulp. A servo-control mechanism is arranged in electrical and controlling cooperation with the induction motor, and is responsive to the rate of rotation of the shaft for maintaining the shaft at a substantially constant rate of rotation when the induction motor is in a power-on state and the comminuting basket is comminuting the food products. A bowl is positioned in substantially surrounding relation to the comminuting basket so as to (i) collect the juice and (ii) direct the juice to an exit opening in the bowel.

Abstract: A weight exercise device for strengthening wrists, arms and shoulders and related muscles. The device includes an elongated cylindrical weight bar having evenly spaced annular grooves formed into its outer surface extending from one end of the weight bar up to a gripping area thereof. The gripping area is preferably defined by an elastomeric foam sleeve secured on the weight bar extending from the other end toward the center area of the weight bar. The device also includes several cylindrical weights of equal length and different weight size each longitudinally bored therethrough for sliding engagement on the weight bar over the grooves. Each weight is held separately or collectively as desired, both with respect to longitudinal positioning and sequence of arrangement on the weight bar by an elastic O-ring fitted into the groove at each end of the weight(s).

Abstract: Apparatus for the manufacture of sulphuric acid by the contact process of the type comprising at least one gas-concentrated sulphuric acid contacting unit and a sulphuric acid heat exchanger characterized in that the contacting unit and/or heat exchanger is formed of high silicon content austenitic steel. The steel is also of use in sulphuric acid concentrations. Reduced corrosion rates are provided.

Abstract: Process for the mononitration of a nitratable organic compound, such as benzene, with a mixed acid in which one of the reactants is delivered into a body of the other reactant in the form of ultra-fine droplets through an atomizing nozzle or similar orifice. The process is economic to construct and operate, is safe and simple to control and leads to a low cost, substantially pure product.

Abstract: The invention provides an apparatus for the manufacture of a coarse emulsion blasting agent and a method for the conversion of same into a sensitive blasting explosive. The apparatus comprises a low shear mechanical mixer in which a coarse emulsion can be continuously prepared. The coarse emulsion is then passed though a fine emulsification motionless mixer for conversion into sensitive explosive.

Abstract: Vesiculated granules of cross-linked carboxylated polyester resin prepared by the free radical polymerization of a dispersion of an ethylenically unsaturated monomer, a carboxylated unsaturated polyester resin having an acid value of from 5-50 mg KOH/g and an alkyl acryloyl derivative. Aqueous compositions comprising the granules are used in conjunction with fibrous cellulosic or non-cellulosic materials for the preparation of paper containing the vesiculated polymeric granules dispersed therein. The paper has improved optical opacity.

Abstract: A rapid, single stage process for the bleaching of high yield lignocellulose pulp (mechanical pulp) to enhanced brightness levels with hydrogen peroxide in the presence of magnesium sulphate and sodium silicate, with a substantial reduction in the wasteful, non-bleaching reactions of hydrogen peroxide. The residual hydrogen peroxide liquor may be recycled to a pulping or bleaching process.

Abstract: An improved plastic film cartridge for flowable explosives is provided. The cartridge comprises a recessed or indented end configuration which recess can be enlarged to provide a locating and retaining pocket for a blasting cap without any penetration of the cartridge film wall. The recess is maintained by means of an internal, elastic cord or strip attached between the sealed ends of the cartridge.

Abstract: A method is provided for loading upwardly extending boreholes in rock with flowable bulk explosives. An explosives loading pipe, an air exhaust pipe and an initiating booster charge with associated initiator are located in the borehole so that the booster and the pipe ends are located deep within the borehole. The ends of the pipes and the initiator are pressed through one or more channels in a cylindrical plug wedged in the borehole opening. Stemming material is first placed in the borehole through the loading pipe to lie against the plug and thereafter the bulk explosive is introduced to fill the borehole. Entrapped air is exhausted through the exhaust pipe.
