Abstract: A low-pressure high-density plasma is excited in a plasma chamber surrounded by a cylindrical inner wall of a ring-shaped waveguide resonator to which the microwave energy is fed by a coupling from a microwave generator. The output coupling of the microwave energy from the standing wave maintained in the waveguide resonator to the plasma chamber is effected through a multiplicity of equispaced slits whose spacing is one half or one waveguide wavelength and which extend parallel to the generatrices of the cylindrical inner wall of the ring-shaped waveguide resonator.

Abstract: A tubular fitting of sheet metal is formed in one piece of a container, for example, a bung container and an internally threaded bushing is press fitted into tubular fitting or is held therein by formations, texturing and/or adhesive and is braced axially against a bead formed on the free end of the tubular fitting.

Abstract: A pipe connection which the insertion piece fits into a sleeve and presses a retaining ring there against. The retaining ring has a compression rib and is constructed so as to be urged into a channel in the sleeve, The ring body is formed unitarily with a sealed lip and a closure lip and a compression-relieving groove opens axially in the direction of insertion and extends almost to but is spaced from a radial plane of the compression rib.

Abstract: Coatings such as high Tc superconductor material on substrates which incorporate reactive gases like oxygen and nitrogen are formed by providing the substrate so that it is spaced from the target region in a coating chamber, forming particles of the coating material by plasma from a cathodic target and entraining the particles to the substrate spaced from the plasma in a gas stream including the reactive gas and at a pressure of 0.1 to 20 mbar.

Abstract: A gas burner for cookers, having an outer burner ring which encloses an inner chamber and whose external periphery is formed with gas outlet openings producing the main flame, an ignition plug and a thermal element which extend into the inner chamber; an inner burner spaced radially inwardly from the outer burner ring and coaxial with the outer ring forming with chamber bottom and limited by the outer ring and to which air for the inner burner is supplied via openings disposed below the burner ring and above the chamber bottom.

Abstract: An assembly of a first expansion stretch, a first throttle, a second throe and a second expansion stretch have respective metal casings and elements defining the flow paths therein composed of engineered ceramics. The throttle are adjustable and the assembly can be used effectively to control pressure and flow rate of compressible or incompressible fluids which can have solid particles entrained therein.

Abstract: The device for preventing abrasive injury from skin in the fat aspirating device is inserted into a biological body and have a bore portion a pipe with a fat aspirating tube 11 capable of being inserted into a biological body through the bore portion and an aperture communicated with the bore portion, as well as a flange 2 connected to the pipe and directly facing the skin of the biological body when the pipe.

Abstract: The compressed air radial motor includes a supporting disc, supporting a plurality of fluid cells, which is pneumatically controlled by a control head disposed rotatably fixed in the motor housing and which is rotatably connected to a conical supporting disc supported on the motor shaft via the fluid cells, a diaphragm being disposed at the outer front side of the control head which, on the inner side, is under the flow pressure of the pressure medium flowing through the driving-side of the control head, and, on the other side, supports the control head against the supporting disc via a counter surface in the motor housing.

Abstract: A drilling device including a hydraulically actuated drive for exerting an oscillatory action on the drive including the drive element, inserting device for hoses conducting a working medium to a pressure-actuated hammer mounted on a front end of the rod and the flushing head at an oscillation angle ranging between 180.degree.-360.degree.. The flushing head is fixed oscilatorily with the drive member and both are swingable about a swivelling axis out of an alignment with the slide and the drive member is formed with a recess for selectively attaching a respective plug-in rod end of the drill rod, so that a torque produced by the drive is transmitted to the drill rod by the drive unit upon interlocking of the flushing head and rod.

Abstract: A hydrostatic-mechanical power-distribution transmission with infinitely variable gear ratio in the hydrostatic branch and several ratios in the mechanical branch, which downstream of the coupling gear has shiftable planetary reduction gears for the purpose of reducing the power contribution of the hydrostatic branch in the starting range.

Abstract: Device and procedure for the supply, with recovery of the raising energy, of press actuators having a cylinder within which a piston delimits two chambers, namely an upper and a lower chamber, which are supplied with pneumatic power, the said device having a pneumatic control unit connected to the mains and including at least one supply line to the upper chamber of the actuator and one supply line to the lower chamber of the actuator, these lines having supply and discharge valves, in which device the supply lines to the chambers of the actuator pass through an economizer unit interposed between the control unit and the actuator and including a servocontrolled valve which intercepts the supply line to the upper chamber, a servocontrolled valve which intercepts the supply line to the lower chamber, and a connecting pipe between the supply line of the lower chamber and that of the upper chamber, downstream of the said intercepting valves, and provided with its own servocontrolled intercepting valve, while means

Abstract: A machine for packaging products by producing boxes of the hinged-lid type which can be closed over a collar with a guarantee seal starting from individual flat blanks with multiple component parts formed by three operationally independent machine sections of modular structure interconnected in the overall machine in an operationally interdependent manner. A first machine section includes an apparatus utilizing a static separation for the supply of the individual blanks in individual sequence to the second machine section comprising a closed-loop conveyor provided with gripper members for supplying the individual blanks to successive stations so that they can be made up in a tubular shape and for transferring them to the third machine section for the operations to fill them with the product to be packaged and their closure with the guarantee seal.
