Abstract: The rotary nasal annular engine with noses on the annular with internal combustion operates on the principle of a pair of the first rotor (1) and the second rotor (2), as well as with usage of a block (3), where the rotors are placed and rotate synchronously. The block (3), together with the circumference surface (1.9), nose (1.2), (1.3) of the rotor (1) and the rotor (2) determinates the engine's combustion chamber (4.1), (4.2) in the shape of a torus, inside of which the rotor (1) is rotating with at least one nose (1.2). The rotor (2), contains, on its outer circumference surface (2.9), slots (2.7, 2.8), preferably, on its outer circumference surface, for the transition of the nose (1.2). During the nose's (1.2) transition through the slot (2.7), of the rotor (2), the compressed medium (7) is transferred through the storage system (2.5) of the rotor (2) through its intake opening (2.4) of the rotor (2) and through the outgoing opening (2.6) of the rotor (2) into the engine's combustion chamber (4.

Abstract: An intervertebral spacer adapted for implanting between adjacent vertebral bodies of a human spine as a load-bearing replacement for a spinal disc. The spacing member may include an external, non-porous, concavo-convex contour with respect to one dimension of the spacing member. The spacing member may be constructed from a rigid, non-resilient load-bearing material that is incapable of elastic deformation. The spacing member may be inserted with the aid of a sheathed trocar device that is releasably attached to the spacer, to enable implantation and selective positioning of the spacer by the surgeon from the posterior side of the spine, without the need to retract the dural nerve or the posterior longitudinal ligament.

Abstract: An oven module for use in industrial baking applications is disclosed having apparatus for accommodating the longitudinal thermal expansion in the interior walls of the oven module located intermediate the ends of the module. The oven module is easily assembled into an oven baking line because its ends are fixed and do not vary due to thermal expansion. Therefore, the present oven module alleviates numerous disadvantages in the shipping and assembly of an oven baking line which has been experienced with prior known oven modules. The floor, walls and roof of the oven module have both an interior and an exterior structure so that the interior surfaces of the oven module can be independently and rigidly supported. At opposite ends of the module, the interior and exterior structures for the floor, walls and roof are fixed to a common support member.
