Abstract: LOCK-UP CLUTCH CONTROL VALVES             ABSTRACT OF THE DISCLOSURE        Control valve assemblies for a lock-up clutch in a vehicle drive system, wherein a torque converter normally couples a prime mover with a transmission, vary the degree of engagement of the lock-up clutch with respect to prime mover rotational speed within  a predetermined speed range.  In the control valve assemblies, a centrifugal valve selectively communicates the fluid pressure operated lock-up clutch with a source of pressure and a fluid drain, with the centrifugal valve having rotor means drivably interconnected with the prime mover.  Spool means slidably received within a rotor bore are outwardly displaceable with a first force while resilient bias means oppose and equalize this first force when the prime mover reaches a first predetermined speed, with valve means regulating the flow of pressurized fluid from the rotor means. Reaction means augment the force of the bias means and permits a gradual engagement of the lock-up clutch which progressively increases until the prime mover attains a second higher predetermined speed at which time the lock-up clutch is fully engaged.  In one instance a modulating balance valve varies the pressure in the lock-up clutch sonsistent with the pressure produced by the action of the centrifugal valve.

Abstract: ABSTRACT OF THE DISCLOSURE           A curing apparatus for continuously producing shaped articles of cross-linked polymeric material in which a curing tube is adapted to be heated by the direct passage of electric current in the tube.          One terminal of a power supply is connected to the opposite ends of the voltage applying section to be heated, while the other terminal of the power supply is connected to the tube at a position where the voltage applying section is divided into two so that one portion on the inlet side of the tube is lower in electric resistance than the other portion on the outlet side thereof. The increased heat generation resulting from the lower electric resistance of the inlet-side portion maintains the tube inlet portion at a high temperature, despite its tendency toward a lower temperature due to continuous introduction of the low-temperature polymeric material to be cured, to thereby achieve an improved production efficiency.

Abstract: CONTINUOUS CASTING PROCESS FOR            PRODUCTION OF METALLIC HOLLOW INGOT          Abstract of the Disclosure The specification discloses a continuous casting process for the production of hollow ingots using improved direct chill casting equipment.  The improved equipment has a molding system comprising a hollow mold and a mov-able platform forming the bottom of the mold.  The mold has a centrally located core and a pipe for introducing atmospheric air to the lower surface of the core.  The core is made from a refractory material unwettable by the molten metal and has a downwardly convergent taper at the sides.  The continuous casting process comprises continuously pouring a molten metal into the space defined between the hollow mold and the core of the above equip-ment; cooling the molten metal only adjacent the side wall of the hollow mold without cooling adjacent the core; thereby solidifying the molten metal to form an ingot having a central hollow portion.  The interface of the solidified metal and the liquid metal is positioned around the core by suitably adjusting the condition and the ingot thus formed is continuously lowered while al-lowing atmospheric air to enter the hollow portion of the ingot via the pipe mentioned above.  The process results in the production of hollow ingots from simple equipment which can be continuously operated without undue difficulty.

Abstract: BOOT FOR MOTORCYCLISTS WITH MEANS FOR          THE REMOVAL OF AIR FROM THE INSIDE     Abstract of the Disclosure The specification discloses a boot particularly adapted for use by motorcyclists.  The boot has a system of channels for changing the air inside the boot on a contin-uous basis when the motorcyclist is in motion.  A first channel is provided near the top of the boot encircling the leg and has inlets and outlets such that air is continuously forced through the channel when the motorcyclist is in motion.  One or more other channels extend vertically down-wardly from the first channel within the boot structure.          These channels also communicate with the atmosphere through a small tube or the like.  The movement of air in the first channel causes recirculation of air through the other channels, which may be connected to the interior of the boot through perforated or foamed divisions. In this way positive recir-culation of air into and from the boot can be provided by means of a relatively inexpensive structure.

Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to paper, or like sheet material, having a coating comprising minute, liquid-containing, pressure-rupturable capsules, and also larger, non-rupturable kaolin-containing stilt capsules arranged in interspersion and in close juxtaposition.  In the preferred embodiment the smaller capsules contain a liquid marking agent.  The capsules, large and small, are interspersed as to size, and are closely spaced on the sheet, so that an intentional impact directed on a small area of the coating will crush substantially all of the small capsules in the area and result in the release of liquid marking agent, whereas casually applied pressure will rupture relatively few of the small capsules in the area.  The marking liquid may be a colorless chromogenic color reactant.  The small capsules on a sheet containing said marking liquid may be associated with other color forming materials on said sheet, or alternatively said color forming materials may be contained on another contacting sheet.
