Abstract: In a mixed cooling system for the piston of a rotary-piston internal combustion engine having a trochoid construction with a triangular piston and a liner surface in the form of a double arc of a circle, a fuel injector is arranged in a side-wall of the liner and its jet is directed toward the inside wall of the corresponding corner of the piston which forms the driving corner of the expansion chamber when the piston is about to reach its bottom dead point. The starting of the injection cycle is determined by a piston position in which the corner of the piston forming the driving corner of the expansion chamber intersects the straight line located in the axis of the injection jet, and the end of the injection cycle is determined by a piston position in which the driving corner of the expansion chamber has moved past the exhaust opening.

Abstract: A rotary piston internal combustion engine of trochoidal type of construction having a housing that consists of dual-curvature mantle runway and side parts, such housing having an eccentric shaft passing therethrough as well as having a triangular piston upon an eccentric of the eccentric shaft, such triangular piston having sealing parts rotating in continuous sliding engagement along a mantle runway in a planetary movement wherein the eccentric shaft is made hollow. The eccentric shaft is produced in a hydraulic pressure procedure. The eccentric shaft is lengthened and extended at an open end thereof via a pipe or tube pressed in the open end and coaxial therewith so as to extend beyond the shaft bearing or receiving of circulating pumps as well as output gears for additional auxiliary devices employable therewith. An end of the eccentric shaft extending beyond the shaft bearing has openings for inlet and discharge of fluid or liquid cooling medium.

Abstract: A reciprocating piston engine having a sealing system between the cylinder head and the cylinder liner, or the cylinder block, using a metal gasket. It is proposed to improve such a system in a manner that, while large manufacturing tolerances are permitted, i.e. tolerances on the dimensional design of the cooperating parts as well as on the cylinder head bolt torque, reliable gastight sealing of the combustion chamber is ensured at all times. This is essentially achieved in that a circumferential raised portion on the liner flange is the only part that projects beyond the top end (sealing face) of the cylinder block and is matched to the metal gasket in a manner that when the cylinder head is tightened down on the cylinder block, the cylinder head gasket is always stressed above the yield point, with the metal gasket having such a stress/strain characteristic that once the yield point is exceeded, the horizontal deformation range (i.e. where the compressive stress is constant) is as great as possible.

Abstract: A filler ring, made of rubber or synthetic material, for a vehicle wheel and pneumatic tire assembly where the beads of the tire are mounted on the radially inner periphery of a wheel rim next to essentially radially inwardly extending rim flanges. The filler ring covers a space located axially inwardly of a rim flange. The filler ring includes at least two planes of circumferential hollow chambers, with the planes of hollow chambers being superimposed on one another in a radial direction, and with at least two hollow chambers, which are successively arranged in an axial direction, being provided in each of the planes of such hollow chambers.

Abstract: A radial seal for a rotary piston engine having a trochoidal-shaped casing inner surfacing and a multi-corner piston with which sealing strips are arranged in radial grooves in the corners of the piston. The sealing strips engage under pressure of the operating chambers against the casing inner peripheral surfacing and respectively against the lower-pressure-side groove wall. The sealing strips have perforations or openings between the sealing surfaces coming into engagement along the groove walls. Filler pieces are inserted or installed with nominal clearance in the perforations or perforations in the sealing strip. These filler pieces are narrower in peripheral direction in the dimensioning or measurement thereof compared with the sealing strip. A spring holds the filler pieces in continuous engagement against an upper part of the sealing strip. Groove clearance of the sealing strip amounts to a value in a range of 0.04 to 0.

Abstract: A multi-blade rotor for a windmill-type apparatus, including a hub supported on a shaft or a fixed angle, and rotor blades that are connected to the hub, via bearing arrangement, in such a way that the rotor blades are rotatable about their longitudinal axes. The inventive easy-to-manufacture, and relatively lightweight, hub has rotationally symmetrical hollow bodies, the number of which correspond to the number of rotor blades. The hollow bodies are mounted on rod-like or tubular pressure members, the number of which correspond to the number of hollow bodies. The pressure members are mounted on the shaft or fixed axle via bearing plates in such a way that their longitudinal central axes are respectively disposed at or nearly at the point of concentration of the bending moment surface of the pertaining hollow body.

Abstract: A method of reducing the NO.sub.x --emissions during combustion of nitrogen-containing fuels via burner units each including a primary burner and being arranged in a wall of a closed combustion chamber; fuel and air for combustion are supplied to the burner flame in stages as partial flows via delivery means which are separate from one another.

Abstract: A method of producing a pneumatic vehicle tire, the beads of which can be mounted on the radially inner periphery of a rim, and are pivotably relative to the bead cores. A carcass along with the adjacent rubber layers, and the tire beads, with their pull and compression resistant cores, are combined on a drum to form an essentially cylindrical blank. What will later be the insides of the tire initially face radially outwardly, and the interfaces of the initially radially outwardly extending beads form an essentially right angle with the cylindrical surface of the blank. At least the bead regions of the tire blank are preliminarily vulcanized, whereupon the blank is turned in and has imparted thereto a toroidal shape. The blank is then provided with a tread strip, and is final-vulcanized.

Abstract: An apparatus for removing soot from the exhaust gases of an internal combustion engine using a loose material filter. The object is to confine the loose material in a particularly effective manner so as to produce a very high degree of soot separation in the filter. This is achieved essentially in that the (loose material) fixing element is composed of two vertically and coaxially disposed perforated tube members that form a first annular chamber, with those surfaces of the perforated tube members that face the first annular chamber being each provided with a fine-mesh screen and adjacent thereto, a coarse mesh screen. The exhaust gas passes through the filter insert transverse to the gravitational effect of the granulate particles. To compact the granulate fill, the first annular chamber can be charged with compressed air via a second annular chamber that is adjacent thereto and is provided in the upper region of the filter housing.

Abstract: A mechanism for feeding animals with liquid feed that can be withdrawn from a supply unit, such as an automatic soaking unit, and can be supplied to a suction unit via a conduit. A feed pump is placed in the conduit, with the conveying capacity of the feed pump being regulatable as a function of vacuum in the conduit.

Abstract: A gas-laser arrangement in which the laser medium is optically pumped. An arc or spark discharge is formed to a helix, particularly by an axial magnetic field. The volume surrounded by the helical arc or spark discharge is optically excited, unimpeded by a physical wall, by radiation from the discharge, especially in the vacuum-uv spectral region, or by resonance lines. Due to the temperature difference between the helical discharge and the gas column along the helix axis, an inversion may be produced in the vicinity of the axis by appropriate choice of gas and the gas composition.

Abstract: A deformable sealing arrangement for the gap between the edge of an opening in a building and the back end of a vehicle that is driven up to the building. An apron that can be deformed by the vehicle is provided. The two side portions of the apron are secured to the side legs of a rigid, U-shaped frame, and the transverse portion of the apron that is disposed above the opening of the building is secured to the transverse leg of the frame. In order to obtain a good sealing effect for various vehicle contours, no matter how close the vehicle is driven to the building, the side portions of the apron are suspended on support arms that are pivotable against a return force, and are movable about a vertical axis. Tension springs are disposed between the upper edge of the side apron portions and the support arms.

Abstract: A radial seal of a rotary piston engine with trochoidal-shaped casing inner peripheral surfacing and multi-corner piston, with which sealing strips are arranged in radial grooves in the corners of the piston. The sealing strips under pressure of the operating chambers of the rotary piston engine engage against the casing inner peripheral surfacing and respectively against under-pressure-side groove wall configuration. The sealing strip along a radial underside thereof has a narrow, deep groove extending parallel to the sides of the sealing strip. A sheet-metal strip is installed with nominal clearance in this first meshing groove and the sheet-metal strip projects beyond the groove. A groove spring for the sealing strip is inserted or installed in the base of this groove.

Abstract: A sausage casing of an isotropic spun fleece of at least one polyamide, containing no binding agent, is joined in the longitudinal direction so as to form a tube and is partially compressed. Further, the invention relates to a process for the production of the sausage casing and its use for containing sausage products that are air-cured. Special mechanical and elastic characteristics are achieved by partial compression whereas the gas and water permeability for the raw sausage is retained to the required extent. The casing shrinks with the filling on curing, remains wrinkle-free, does not allow grease to escape, and can be easily peeled.

A righting aid is provided that is in the form of a pole-like righting element that has two ends, a first one of which is detachably connected to the watercraft in such a way that, essentially on a line at right angles to the plane of buoyancy, and essentially at the level of the center of gravity of the watercraft, the righting element is pivotable along at least one axis of freedom. The other end of the righting element is pivotable essentially orthogonally relative to the longitudinal axis of the watercraft for righting the latter when it has capsized.

Abstract: A method of purifying flue gas from the firing equipment of a combustion unit, especially fuel gas from fitting equipment to which low-ash flue is supplied, or from a grating firing having a high degree of ash removal, with the flue gas containing noxious compounds. A finely divided or pulverous basic additive is used on which the noxious compounds produced during firing are adsorbed. Flue dust, especially flue dust/additive mixture, that is carried along in the flue gas is separated from the latter, with at least a portion of the separated-off flue dust being hydrated and sifted, whereby subsequently at least a portion of the dry, hydrated flue dust is returned to the flue gas purification process. Non-pulverized flue dust is homogenously mixed with finely sprayed water to effect the hydration. The return of flue dust to the flue gas purification process is undertaken by returning at least a portion of dry, thus-hydrated flue dust to the firing equipment of the combustion unit.
