A mixing capsule for mixing a first material with a second material, and in particular, a capsule in which the materials are kept separated and brought together only at the time they are to be mixed. The capsule is characterized by a pierceable partition which separates the materials to be mixed, a projection for piercing the partition and two grooves and a ridge. One of the grooves cooperates with the ridge so as to maintain the projection away from the pierceable partition during storage and transport. The other groove cooperates with the ridge so as to hold the mixing capsule together and prevent leakage once the partition is pierced.

Mixing capsule having three tubular members

An engine ignition timing control system and method wherein a timing module associated with a given engine includes a read only memory and circuitry for generating information related to engine crankshaft rotation. The module memory is programmed with information relating piston position to crankshaft rotation. The crankshaft rotation and piston position information is made available to an on-board ignition computer for precise control of ignition angle. Also disclosed are a system and method for separately programming the module memory associated with each engine as a function of the piston mechanics of that engine.

Ignition timing control for internal combustion engines

A probe assembly for injection of microwave energy into the cylinder cavity of a diesel engine and detection of luminescence indicative of fuel ignition in the cylinder. The probe assembly comprises a probe with microwave and optical transmitters extending axially therethrough adapted to be threaded into a cylinder opening. A coupler is removably mounted on the probe and includes an optical detector mounted in assembly coaxially with the optical transmitter in the probe and a microwave antenna coupled by a waveguide cavity within the coupler to the probe microwave transmitter. The coupler is adapted for connection to suitable external diagnostic circuitry for providing to such circuitry signals indicative of piston position within the cylinder and fuel ignition as a function of the microwave and luminescence signals respectively.
