Abstract: BLIND FASTENER ABSTRACT OF THE DISCLOSURE           A collapsible fastener and method of making same for joining workpieces which fastener can be fabricated with  a  single  machining  operation  aside  from  thread tapping.   The fastener comprises a forged sleeve defined by cylindrical exterior and interior surfaces.  The sleeve has a head (12) at one end for bearing against one surface of the workpieces,  internally threaded tail  (13), and a shank (11)  extending between the head and the tail.   A plurality of extruded grooves (14) on the exterior surface of the shank are parallel to the axis of the sleeve.  An extruded notch (15) in each groove is at substantially the same distance from the head.  When a mandrel is extended through the head and the shank and is threaded into the tail, by turning the mandrel the tail may be drawn toward the head whereby the shank splits into strips which fold at the notches.

Abstract: The method entails passing impure gases from an incineration plant such as a destructor, process furnace, crematory furnace or heating boiler, through a burner in an afterburner where through enforced mixture with combustion gas they undergo complete combustion. The combustion gas, depending on the composition of the flue gases, may consist of air or oxygen or either mixed with liquid petroleum gas. 
<??>In the device for implementation of the method the flue gases and the combustion gas are introduced into a burner (10, 44) which blows the gas mixture into a flame bowl (3, 52) where temperatures in the 1500 - 2000 DEG C range can be achieved. In one version of the invention the burner (44) produces a conical basketshaped flame in which the flue gases undergo complete combustion.

Abstract: The invention relates to a receiving arrangement 4-1 for SHF signals, comprising a rectangular waveguide filter 5 formed from resonators 10-1 to 10-4 arranged in cascade, a SHF signal arrangement 6 containing a microstrip circuit and a microstrip to waveguide filter transition connection to this circuit.Generally, such a receiving arrangement is not suitable for use in radiators comprising a partly shown polarization converter 3 with two such receiving arrangement 4-1 each receiving one of two mutually orthogonally polarized signals. When the prior art receiving arrangements are used in these radiators, the channel separation is inadequate.According to the invention, an adequate channel separation is obtained by providing the microstrip to waveguide filter transition in the waveguide filter and matching the filter 5 thereto. As a result thereof, the receiving arrangement 4-1 becomes more compact and has a very low reflection and, in addition, it is no longer necessary to adjust the transition to the waveguide filter 5.Preferably, dimensioning is realized by the choice of the size in the axial direction of the end resonator 10-4 and/or the choice of the dimensions of the coupling aperture which connects the end resonator 10-4 to the adjacent resonator 10-3.
