The invention may be employed as a wheel-engine of a vehicle, comprising functions of internal combustion engine and of non-gradual speed gear-box and directed to the simplification of the construction, lessening of dimensions and depletion of fuel. The drive of propulsion device comprises a propulsion device in the form of a rim (1), mounted with possibility of rotation, a piston engine, placed inside of it, with a block (2) of cylinders having at least one piston (3), installed in it with possibility of reciprocating movement in the direction radial to the axis of rotation (9) of the rim, a mechanism for transmission of the movement of the piston into a rotating movement of the rim. The mechanism for transmission of the movement of the piston into a rotating movement of the rim is equipped with eccentric driving axes (15), mounted on each connecting rod with possibility of swinging and interaction with grooves, made aslant towards the radial about the center of rotation of the rim line on the block of cylinders, or on the levers (19) or turn disks (20) mounted on it and simultaneous interaction with radial grooves, made on swing lever (21), mounted on the center of rotation of the rim on the block of cylinders and equipped as well with at least one overrunning clutch mounted on the swing lever with possibility of interaction with the rim.

The current invention relates to a foam insulating material made of athermanous materials containing expandable styrene polymer particles. The material according to the invention consists of so-called reflector particles and absorption particles. The material according to the invention is especially advantageous in sheet form for thermal insulation and therefore for insulation purposes in buildings, but also for other applications. It is also possible to achieve an improved sound absorption with the material according to the invention.

The present inventions are related to machine - building and are aimed at increase of efficiency and softness of work. The variants of the internal combustion engine include rim, installed with possibility of rotation, and having orbital running-tracks in the form of T-shaped groove of oviform or another, secluded and centrosymmetrical form, embraced by these running-tracks non rotating block of cylinders, radial coming together by combustion chamber and having pistons inside, and also there are connecting- rods, hingedly connected with cylinders and with arranged on cylinder block one- armed levers, where the connecting-rods have pinch rolls on the other ends, contacting with running-tracks. Cylinder block is arranged with possibility of operated displacement from the axis of rim rotation, the engine is provided with means for realization of this displacement. The rim is arranged with the possibility of synchronous, plane-parallel transfer by cycle in diameter less than piston stroke, besides the engine is provided with the means for this transfer. When making engine with four-stroke cycle of action, the hackles at orbital running- tracks are carried out even-numbered and/or the number of cylinders is odd- numbered and more than number of hackles.

An inductive coupler 33 provides an interface between a power line and a communication device which communicates vi the power line The power line operates at a potential between four and 140 kilovolts while accommodating a current havi a frequency between 45 and 65 hertz, and the communication device operates substantially at ground potential The inductive coupler includes a split ferrite core 10, 13 having material selected to provide a substantially flat frequency response between one and 50 megahertz The coupler also includes a clamping mechanism 17, 27 allowing the inductive coupler to clamp around the power line or around a utility line connected to the power line Further, the coupler includes a least one lead 77 for communicatively connecting the inductive coupler to the communication device The inductive coupl forms an air gap 8 when the inductive coupler is clamped If the coupler is insulated, the insulation is also used for the air gap.

A radio frequency (RF) signal coupler (120) for cooperative engagement with a shunt device (110) and for cooperative engagement with an RF mode. The shunt device has a high voltage terminal (112) connected to an electrical cable of the power network (111) and a low voltage terminal (114). The coupler comprises a signal lead (123) connected to the low voltage terminal of the shunt device, a ground lead (132) connected to earth ground, and a coupling transformer (130). The coupling transformer comprises a ferrite ring (124), a multiple turn primary winding (126) having a first end and a second end, the first end being connected to the signal lead and the second end being connected to the ground lead, and a multiple turn secondary winding (125) having two terminals for providing the RF signal to th RF modem. The ratio of turns of the secondary winding to the turns of the primary winding is at least two to one.

Many herbicidal compositions have been developed and practically used. However, types of weeds to be controlled are also many, and their emergence extends over a long period. Accordingly, it is desired that a herbicidal composition be developed which has a wider herbicidal spectrum and which is highly active and has a long lasting effect. As a result of a research to solve such problems, the present inventors have found it possible to obtain a highly practical herbicidal composition by a combined use of (A) 2-(4,6-dimethoxypyrimidin-2-ylcarbamoylsulfamoyl)-N,N-dimethylnicotinamide or its salt and (B) N2-tert-butyl-6-chloro-N4-ethyl-1,3,5-triazine-2,4-diamine or its salt, and thus have accomplished the present invention.

A set of three low cost processes for removing boron, phosphorus, carbon and other metal and nonmetal impurities during the process of converting metallurgical grade silicon to electronic grade silicon. One process removes boron by using one or more high temperature solids removal devices to remove solid titanium diboride from a halosilane reactor effluent stream where the high temperature is preferably greater than 200 C, more preferably greater than 300 C and most preferably greater than 400 C . A second process removes carbon as methane and phosphorus as phosphine by means of a membrane separator which processes all or part of a hydrogen recycle stream to recover hydrogen while rejecting methane and phosphine. A third process separates a high boiling halosilane stream into a large low impurity stream and one or more small high impurity streams some of which can be sent for halogen recovery.
