Abstract: An apparatus for blending two different components, comprising: two vessels each containing one of said components, connection means to which said components are separately fed from said vessel, and an actuation device which initiates the entry of the components into said connection means from said vessels at a predetermined ratio, where a pressurized vessel each is provided as a vessel from which said component is discharged by means of an expulsion agent via a valve, the valves of said vessels being operated via the actuation device.

Abstract: A discharge valve for discharge of pressurized fluid, foam, gel or similar materials includes a sack made out of flexible film material, which is flat welded in a border area in two superimposed layers and a receptacle body, the body being welded in the border area between the two layers of the film material. The valve further includes a valve stem, which is made of an essentially impermeable synthetic material to organic media and has a tubular section, whereby the receptacle body has either a tubular appendage or a corresponding receptacle and the valve stem has either an appendage or receptacle as counterpart for the receptacle body in order to connect the receptacle body and the valve stem with each other using a clamp connection. A gasket arranged between the receptacle body and valve stem at least partially covers the receptacle body on its side facing the valve stem.

Abstract: The invention relates to a pyrotechnically operated bolt-setting tool having a barrel (11, 12) which is guided in a barrel-guiding sleeve (1) and can be brought into operative engagement with a locking part (18), the barrel-guiding bore (26) of which accommodates a piston (21), which has a piston shank (23) and a piston head (22), and which has a cartridge store (16) on that side which is remote from the mouth, in which bolt-setting tool the barrel (11, 12), on its side which faces the cartridge store (16), has ventilation slots (31) which are released by the piston head (22) as the bolt is being fired, before the piston (21) reaches its end position on the mouth side, in which position an air cushion is compressed between the piston head (22) and the barrel (11, 12), which air cushion subsequently presses the piston (21) back into its starting position.

Abstract: The invention relates to an explosive powder charge operated bolt-setting tool having a bolt guide (2) which has a through bore (4) for explosive powder charge actuable driving piston (5), a ball brake being provided for the driving piston (5), which brake is designed as a freewheel for the return of the driving piston (5) and comprises a recess (9), which is open radially towards the driving piston (5) and has two spring-loaded brake balls (12) each of which are accommodated therein, and which bear against the driving piston (5) and which can be moved, with maximum and minimum spring loading, between two axial stops (3, 16) along an oblique surface (15) which widens conically at an acute angle towards the driving piston (5).

Abstract: A weapon bolt assembly includes a bolt portion including a recess; a firing pin unit including a striker plunger axially slidably received in the recess and having an axially measured length and a firing pin attached to the striker plunger. The firing pin unit has a first position in which the firing pin projects from the bolt portion and a second position in which the firing pin is situated in its entirety within the bolt portion. A firing spring is disposed in the recess and has a relaxed state and a stressed state. In the relaxed state of the firing spring and in the first position of the firing pin unit a clearance is defined between the two components. In the stressed state the firing spring exerts a force on the firing pin unit urging it into its first position. The axially measured length of the firing pin unit is such that in the second position the firing spring remains in the relaxed state.
