A combination cheese-grater/music-maker device is provided such that grated cheese and musical notes are produced simultaneously and synchronously. The device uses of one or more cylinders rotatably attached to said device wherein all of the cylinders can be rotated simultaneously and synchronously. The device features with a handle to allow a person's hand to impart simultaneous and synchronous rotation to all said cylinders. Musical note producing elements are attached to the device such that a note is produced when a protrusion on a cylinder contacts one such element. The device also features cheese-grating sections on one or more cylinders and with a surface to impart downward pressure on the cheese to facilitate contact of the cheese with the sections.

A unipivot tone arm assembly wherein the tone arm is supported by a single point is balanced in such a way as to have neutral stability providing constant tracking force over the peaks and valleys of phonograph records. Lateral stability lacking in a neutral balanced unipivot tone arm is provided by magnetic coupling between magnets on the tone arm housing assembly and a freely rotating platform. Anti-skate is accomplished through a pulley mechanism between the rotating platform and the tone arm gantry, with the pulley on a counterweighted rotating pivot arm.

Methods for the recovery of bitumen from tar sands comprising the steps of mixing tar sand, solvent and a displacing amount of aqueous medium to form a mixture, followed by separating a bitumen-rich solvent phase from the mixture and recovering bitumen from the bitumen-rich solvent phase are disclosed.

Methods of tar sand bitumen recovery

A method for the recovery of bitumen from tar sand comprises slurrying tar sand with about 0.5 to about 4.0 pound of a organic solvent per pound of tar sand, then adding greater than about 0.50 pound water per pound of tar sand, and separating a bitumen rich solvent phase. The method has the advantage of permitting separation of sand from the bitumen rich solvent extract without formation of a stable emulsion.

Method for solvent treating of tar sands with water displacement

Apparatus for straightening metal flanges of a cylindrical spool having a center longitudinal portion with a planar flange perpendicularly mounted upon each end thereof. The apparatus includes a pair of movable jaw assemblies which first engage the center longitudinal portion of the spool and then expand to provide a rigid support adjacent the inner planar surfaces of the spool flanges. A hydraulic control system is provided which senses the fully extended engagement of the movable jaw assemblies with the spool, and then actuates a hydraulic press to engage the outer surfaces of the spool flanges. The flanges are compressed between the movable jaw assemblies and the hydraulic press, thereby straightening out irregularities in the flanges. A second sensing device detects when the hydraulic press has reached its fully extended position and then actuates a control system which retracts both the movable jaw assemblies and the hydraulic press, thereby releasing the spool and resetting the system for the next cycle.
