Abstract: ABSTRACT OF THE DISCLOSURE A conventional outside seal assembly is disposed outside the stuffing box which surrounds a rotatable shaft.  A thermally conductive packing structure is disposed within the stuffing box in concentric and surrounding relationship to the shaft.  The packing structure facilitates the transfer of heat from the shaft and the fluid radially outwardly to the stuffing box, and thence to the surrounding atmosphere.  The packing structure has thermal insulators associated therewith for preventing heat from being transmitted axially toward the seal assembly, thereby permitting the seal assembly to operate at a lower temperature.  This pack-ing structure, in a preferred embodiment, utilizes a plurality of annular packing rings constructed of a thermally conductive material, which packing rings are axially aligned and are spaced apart by intermediate washerlike insulators.  The seal assembly preferably has a bladed fan secured to the rotatable part thereof for increasing the air flow across the seal faces and the stuffing box.

The apparatus comprises an index signal generator for generating a periodic index signal as the index elements are scanned by the beam. Color gates are provided for sequentially gating respective color control signals individually to modulate the electron beam as that beam scans the color elements. A gating signal generator generates sequential gating signals at a frequency synchronized with the frequency of the periodic index signal. These gating signals are supplied in sequence to the color gates to control the latter so as to gate the respective color control signals. A driving circuit responds to the periodic index signal to drive the gating signal generator. The driving circuit includes a time adjustment circuit for compensating the inherent time delay of the overall apparatus such that the respective color control signals are gated in time correspondence with the position of the beam at a color element that is associated with the gated color control signal.     -i-

Abstract: INDICATOR FOR HEATING UNIT FOR DISINFECTING   SOFT LENSES, OR THE LIKE     A B S T R A C T     An indicator is provided for a heating unit, which heating unit may be used as a soft contact lens disinfecting means, and which includes wax as a heat transfer medium, as a temperature sta-bilization means, and as a heat storage medium.  In accordance with the present invention, an indicator assembly for such a heating unit is provided, and which indicates to the user when the unit is ener-gized, when the unit has reached its proper operating temperature, and when the unit has completed a heating, disinfecting cycle.  The indicator assembly of the invention is in the form of a hollow plug which extends into the interior of the heating unit, and which it-self is filled with wax.  The plug has an indicator disc, which may be of a bright color such as red, attached to its bottom to be visible through the wax in the plug and through the transparent cover of the plug only when the wax within the plug is in a trans-parent molten state.  Since the plug is in contact with the wax in the heating unit itself, the fact that the wax in the plug has reached a transparent molten state is an indication that the wax within the heating unit is also in a molten state, and that the heat-ing unit has reached its operating temperature.  The plug also in-cludes a light pipe which extends through it, and which enables the user to see an electric light bulb which is buried in the wax within the interior of the heating unit, and which is energized when the heating unit is energized.

Abstract: ABSTRACT OF THE DISCLOSURE          A pigment-free coating composition comprising an acidic dispersion of colloidal titanic, colloidal silica and hydroxylated silsesquioxane in an alcohol-water medium.  A coating of the composition cured on a plastic substrate such as polycarbonate results in a hard, abrasion-resistant protective coating.  Such coatings transmit visible light, but absorb wavelengths of ultraviolet light which cause degradation of the substrate surface and resultant adhesion-loss of the protective coating upon weathering. A cured coating of these compositions deposited on metal substrates such as aluminum results in a hard, abrasion resistant coating which offers slightly more corrosion protection than such a composition without colloidal titania,

Abstract: ABSTRACT OF THE DISCLOSURE           The manual starter for an internal combustion engine includes a flexible pull element mounted in the vicinity of the engine flywheel for movement between a normally retracted position and an extended position and having teeth or cogs adapted to drivingly engage teeth provided on the outer peripheral surface of the flywheel.  When the pull element is pulled to an extended position, a rocker arm cooperating with the pull element moves the pull element to a drive position wherein the cogs drivingly engage the flywheel teeth to effect starting rotation of the flywheel.  When the pull element is released or the rotational speed of the flywheel exceeds the pulled speed of the pull element after the engine has started, the rocker arm permits the pull element to move from the drive position to a non-drive position wherein the cogs are drivingly dis-engaged from the flywheel teeth.

Abstract: ABSTRACT:           Growth of a layer from the vapour phase is con-trolled at low temperatures by reactions.  The result is a homogeneously thick layer.  At high temperatures the layer growth is controlled by diffusion in the gaseous phase.  The homogeneity of the thickness may then present problems.  At low pressure the temperature range over which the growth is determined kinetically is larger but the temperature is then still too low for monocrystalline growth.  According to the invention, for homogeneously thick monocrystalline growth there is started from a gas mixture which is in equilibrium with the material to be grown and growth takes place in a temperature gradient in the direction of flow of the gas mixture.

Abstract: CHOKE FOR CONTROLLING THE FLOW OF            DRILLING MUD        Abstract of the Disclosure The invention concerns a choke for controlling the flow of high pressure drilling lubricant to a drilling bit.  In one form, the choke of the present device is an elongate tubular housing having in one end a closure or plug which entraps a fluid operated piston.  The piston is made double-acting by applying pressure to both faces controllably.          The piston has a centralized plug appended to it which receives thereabout a valve member formed of an extremely hard material.  It is located in a circular chamber which communicates with a lateral port where the mud flow from the well is introduced.  The lateral port is directed at the valve element which is able to withstand the wear of the flow.  The apparatus further includes a circular valve seat which is inserted downstream.  The valve seat is also made of hardened material and has a tapered leading edge.  It has an edge which matches or mates with the valve element, itself.  As the two are brought together, they close off the passage through the choke.  The valve seat is a hollow circular ring which communicates with an outlet passage.
