Title: Microwave heating system
Inventor: ZAKARIA ZAIRANI
IPC: H05B6/80
Filed: 1991-05-03
Abstract: ABSTRACT OF THE DISCLOSURE            A microwave heating system is disclosed which is especially useful for rapidly, uniformly and positively sterilizing biological media, such as broths and gels used as incubation or growth media for bacteria, which system includes a source of microwave radiation, a microwave chamber, a container or a plurality of containers in the chamber, and mixing means for mixing contents of the container or containers during heating thereof, which mixing means are at least partially external to the container and are capable of operating when the container is positively sealed to prevent contamination of the contents thereof.  The mixing means is preferably a combination of an external magnet and a mixer which is at least in part of magnetic material (material responsive to a magnetic field) and is moved by changes in the magnetic field set up by the magnet, as the container and contained mixer are moved with respect to the magnet, as on an oscillating turntable.  Other means for mixing the material in the container are also within the invention, although they are not as satisfactory as the magnetic means described, and such other means include mechanical means, such as solenoid activated cores or extensions thereof for pushing vertically against a turntable and thereby moving it out of its normal horizontal plane, cam means for accomplishing the same purpose, means for causing the containers to swing, in pendulum-like motion, as they are rotated, and ultrasonic means.  Although the described system is ideal for sterilizing biological media, which may be in sealed containers and protected from contamination, and which may be positively sterilized, under pressure, as is often desirable, more efficient and faster microwave heatings are also obtainable for other operations, such as digestions, chemical reactions, dryings, analyses, and preparations of materials for analyses.          Also, the invention may be utilized for mixing without microwave heating.

Filed: 1991-07-22
Abstract: An internal combustion engine has first and second cylinders, the first cylinder having a larger swept volume than the second cylinder and the second cylinder being formed in the crown of the first cylinder. First and second pistons are reciprocable respectively in the first and second cylinders, the second piston being formed as a protrusion on the crown of the first piston. The first cylinder has an air inlet and an exhaust outlet whilst a first fuel source provides fuel to the second cylinder. The second piston has a crown which is spaced from and connected to the crown of the first piston and which has an edge which is relatively thin in the axial direction compared to the spacing of the first piston crown from the second piston crown. This defines a combustion space between the piston crowns and a side wall of the second cylinder when the pistons are substantially at the inner dead centre position. The combustion space communicates with both cylinders during part of the expansion stroke. Inhibiting means is also provided for inhibiting ingression prior to the pistons arriving at or adjacent the inner dead centre position. This can take the form of a gap between the second piston crown and the second cylinder side wall with a peripheral groove in the second cylinder wall at its upper end to enable the fuel/air mixture in the second cylinder above the crown to bypass the piston crown when the latter is at its inner dead centre position and enter the combustion space.
