Abstract: Novel siloxane compounds containing a SiH group, an alkoxy or epoxy group-containing organic group attached to a silicon atom, and a perfluoropolyether group-containing organic group, each at least one per molecule, are useful tackifiers for imparting good adhesion to various resins and even fluorinated silicone resins.

Abstract: A turbo-compound compressor system includes a booster compressor connected to the output shaft of a power recovery turbine which is disposed downstream of the outlet of an expansion turbine in a turbocharger for an internal combustion engine and drivable by the exhaust gas of the engine, and a rotary positive-displacement air compressor drivable by the engine also into which the air delivered by the booster compressor is supplied through an air supply conduit having a throttle valve. The turbo-compound compressor system further includes a bypass line provided therein with a closing valve and adapted to prevent surging caused in the booster compressor.

Abstract: This disclosure relates to a coolant system for an internal combustion engine including a turbocharger and an aftercooler. The coolant system comprises an engine loop and an aftercooler loop both loops utilizing a single pump. The engine loop includes the pump, the engine block and head, a first radiator, and a radiator bypass branch. The aftercooler loop includes the pump, the aftercooler, a second radiator, and a radiator bypass branch. Each loop further includes a temperature responsive flow control thermostat for regulating the coolant flow through the associated radiator and/or bypass branch. The thermostat in the aftercooler loop is mounted in the coolant intake line leading to the aftercooler, but it responds to the temperature of the coolant leaving the aftercooler.

Abstract: A turbine housing for a centrifugal turbosupercharger comprising a spiral wall defining a gas passage through which exhaust gas from an engine passes and a partition wall dividing said gas passage into two passages wherein the height of the partition wall gradually decreases in the downstream direction. In such a manner that the gap between the outer periphery of a turbine rotor and the tip of the partition wall reaches a maximum at about 225.degree. as measured from an intersection of the inner periphery of the partition wall and a line passing through the center of the turbine rotor and drawn perpendicular to the direction of introduction of exhaust gas.
