Abstract: TITLE OF THE INVENTION          "METHOD AND APPARATUS FOR CRUSHING MATERIALS SUCH AS                   MINERALS "     ABSTRACT OF THE DISCLOSURE Lumps of a mineral or like material comprising two or more solid phases at least one of which is electrically semi-conductive and of different conductivity and permittivity from the other or others are subjected while immersed in water or other high dielectric medium, to the action of an electrical discharge of high enough potential to ionize the mineral.  The discharge so generated crushes the lump.  The electrodes between which the discharge occurs are so arranged that the discharge is substantially wholly dissipated in the lump.  The invention is especially useful for freeing diamond from kimberlite.

Abstract: Abstract of the Disclosure An interactive, computer-based system for combining on a common display (40), as overlaid images, video signals from a source of video images (such as a video disc player; 20) with graphics and text from a computer (30), particularly for use in computer-aided instruction, computer-based information retrieval and visual annotation or supplementation of video images.  The video signals are converted to RGB format (or some other non-phase-modulated format) by a format converter (80) if not already so encoded.  They are then supplied to a switch (90) which receives the text and graphics-signals, also in RGB format, as another input.  The output of the switch is supplied to a video display (40) A The switch is controlled by an attribute of the text and graphics signals, for controlling the selection of the video source on a pixel-by-pixel basis.  A keyboard (70) or other device connected to the computer allows the user to provide input and, responsive thereto, the computer directs the operation of the video source, such as changing frames on a video disc, providing image enhancement or masking. etc.

Abstract: ABSTRACT      A method and apparatus for changing the operational state of an optical or optoelectronic sighting device from the READY state to an operational state and vice versa, wherein the change in the state of the device is effected automatically, thereby freeing the user's hands for use in other immediate tasks.  The apparatus comprises an eyepiece, a deformable eye rest, shutter means formed integrally therewith, transmitter means, receiver means, reflecting means fixed to the shutter means, and switch means.  In the READY state, only those parts of the apparatus which require a relatively longer start-up time are energized.   Also, in the READY state, a beam is transmitted from the transmitter means to the reflecting means and then back to the receiver means.  When the user presses his head against the deformable eye rest, the eye rest deforms and the shutter means opens, uncovering the sight channel formed by the eyepiece and the eye rest.          Also, the optical path of the transmitter beam is interrupted. The switch means opens in response to this interruption, thereby fully energizing the apparatus and transferring it from the READY state to its operational state.  When the head of the user is removed, the shutter means are restored to the closed position and the apparatus is switched back to the READY state.

Abstract: ABSTRACT             There is disclosed a method for imparting a decorative or printed pattern to the surface of rotationally molded products during their manufacture and a pattern transfer used in that method.  The decorative pattern is formed on a transfer sheet film as a coating of pigments dispersed in a hydrocarbon wax which overlays a release agent, such as a silicone coating on the sheet film.  The decorative wax pattern is applied to a preselected area of an inside wall of the rotational molding cavity by positioning the pattern transfer against the surface of the wall and burnishing the pattern onto the interior wall of the mold cavity.  Thereafter, the particulate molding resin is charged to the cavity and the product is molded in a conventional procedure, resulting in transfer of the pattern into the resin, with the pigments incorporated in the resin product and with most of the wax excluded from the product.

Abstract: ABSTRACT OF THE DISCLOSURE     The present invention relates to a receptacle having a normally disguised message printed on a surface of the receptacle.   Clusters of variegated elements are arranged in respective predetermined colour patterns on the surface to display  to  the  naked  eye  random  colour  arrangements which disguise  the message.   Each  respective  colour ar-rangement disguises a portion of the message which may com-prise  a  numeral  or  a  letter  of  the  alphabet.    Certain colours in each respective predetermined colour arrangement of variegated elements are accentuated to display the mes-sage  when  the  predetermined  colour  pattern  is  viewed through a coloured filter.  This novel method of disguising a  message  on  a  receptacle  finds  advantage  in  that  the clusters may be printed on the receptacle at the same time as other art work, trade names and so on are printed on the receptacle.

Abstract: "STATIC BENDING APPARATUS FOR GRADING WOOD PANELS"             ABSTRACT OF THE DISCLOSURE A non-destructive method and apparatus is provided for testing a wood panel, such as a sheet of plywood, to establish values which may be used in calculating a measure of the modulus of elasticity (MOE) for the panel.  The invention involves supporting the bottom surface of the panel horizontally with two spaced parallel rollers and contacting the top surface of the panel with a pivotally mounted loading bar which is adapted to apply linear loading to the panel substantially uniformly across its width, even though the panel may be warped or bent.  The loading bar is biased by a double-acting cylinder so as to apply a first load and then, in quick succession, a second incremental load.  The two loads are selected so as to fall on the substantially linear portion of the load deflection curve for the panel.  The magnitudes of the two loads are measured with suitable means, such as a load cell.  The extension or distance moved by the cylinder in applying the incremental load is known or measured.  With the two loadings and the incremental deflection established, one can calculate,using standard formulae, a value which is found to closely approximate the MOE.
