Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus for repairing or relining an underground pipeline without having to excavate the pipe is enabled by attaching an expandable sealing unit to the end of a predetermined length of flexible tubing and feeding it through the pipeline.  The flexible tubing is fed through the existing pipeline from a point beyond where the existing pipeline exits the earth, usually within the basement of a building.  Once positioned in the desired location, the expandable sealing unit is expanded to form a tight seal at the desired location within the pipe by means of heating the expandable sealing unit by a heating unit connected to the source of energy through electrical conductors which pass through the flexible tubing.

Abstract: ABSTRACT A practice projectile (56...79), for large-calibre guns from 40 mm upwards, is to be equivalent - in trajectory and accuracy - to a combat shell over an initial portion of the trajectory.  At the beginning of the second portion of the trajectory, the projectile is to self-destruct in such a manner that none of the parts (2...50) thereof fly beyond the second portion of the trajectory.   This is achieved by means of a plurality of pyrotechnical delayed-action fuses (15, 31) which are ignited when the projectile is fired and which, after burning up, ignite gas generators (15, 30).  The pressurized gas produced by the gas generators ruptures the connections which hold the projectile together.  Individual components of the projectile are separated from each other either by compressed gas and/or by dynamic air-pressure and by the residual spin of the projectile.

Abstract: ABSTRACT OF THE DISCLOSURE     A crosslinking additive for imparting water resistance to starch-based corrugating adhesive compositions is prepared by reacting acetone and formaldehyde under aqueous alkaline conditions at 20-80°C in a molar ratio of I mole acetone to about 2 to 5.5 moles formaldehyde. adding to the reaction mixture at least an effective amount of dihydroxyethylene urea to scavenge the free formaldehyde in the mixture, and reacting until the amount of unreacted formaldehyde remaining is reduced to about 0.1-2%.  The crosslinking additive thus obtained, which is low in free formaldehyde, may be added directly to a starch-based corrugating ad-hesive or may be first mixed with dimethylol dihydroxyethylene urea.

Abstract: 039.153       EXHAUST ASSEMBLY FOR TRACTORS                 ABSTRACT OF THE DISCLOSURE     An exhaust assembly for a tractor having a pivotal or slidable engine hood that must be moved out of the way to permit an operator complete access into the engine compartment. The exhaust assembly includes a tubular housing positioned within the engine compartment below the top surface of the engine hood. The tubular housing has a cylindrically shaped inlet conduit adapted to be connected to the exhaust manifold of the tractor engine. Exhaust gases are forced vertically into the inlet conduit and then directed in a horizontal swirling fashion through the tubular housing by apertures and baffles along the length of the inlet conduit. The tubular housing further includes a cylindrically shaped outlet conduit having an open conical discharge end which is in close proximity to the lower end of an elongated exhaust tube that is attached to the engine hood. The exhaust gases are forced into the outlet conduit through apertures in its periphery and then directed by baffles vertically out through the conical end of the outlet conduit and into the lower end of the exhaust tube for discharge. The exhaust tube includes outer and inner concentric shells with the outer shell being solid and the inner shell having apertures and baffles spirally arranged around its periphery for cooling, diluting, and muffling the exhaust gases and producing an aspirating effect for drawing and discharging the exhaust gases. The lower end of the exhaust tube surrounds the conical end of the outlet conduit to form an annular opening for drawing air and fumes from the engine compartment into the exhaust tube along with the exhaust gases.

Abstract: ABSTRACT OF DISCLOSURE AIR REGISTER WITH AUTOMATIC ZONE CONTROL     An air register for distributing air to a room has a thermally responsive actuator element in direct contact with a pivotably mounted closure slat for controlling the flow of air through the register.  The air is dis-tributed upwardly along the wall of a room and a ven-turi, mounted in the air flow path, draws air in through an opening in the front of the register and over the actuator so that the actuator senses room temperature of the treated air passing through the register.  The slats which control the flow of air through the register are biased in an open position and the actuator tends to close the slats through a direct linear force on the slats.
