Abstract: A projectile with an ejecting charge for the expulsion of a payload. The ejecting charge effectively develops a pressure which is of sufficient duration and adequately high for effectuating the expulsion of the payload; however, wherein the casing thereof will not burst into the kind of fragments which conceivably can damage the payload. A receiving member for the ejecting charge is mounted within the projectile, which receiving member withstands the development of the pressure encountered during the combusting of the ejecting charge; wherein that the receiving member possesses a multiplicity of apertures through which there discharges the propellent gas which is developed during the combustion of the ejecting charge, and wherein the ejecting charge is inserted into a thin-walled cup contained in the receiving member.

Abstract: A fuze for a bomblet including a slider in which there is arranged a detonator triggered in response to an impact or percussion, and which undergoes a transition during the free flight of the bomblet from a safe or secured position into an armed position. Arranged in the slider is a hydraulic or penumatic cylinder-piston retarding device and a spring-biased self-destruct pin which is operatively coupled to the device, which has a self-destruct detonator associated therewith, wherein the retarding device is blocked until the slider is generally located in the armed position thereof, and in which the retarding device, in the armed position of the slider, will brake the movement of the self-destruct pin during a self-destruct time period and thereafter will cause the releast of the latter.

Abstract: A safe-and-arm or securing device for the fuze of a spinning or spin-stabilized projectile which includes a fuze member and a supporting member in which a spherical rotor is rotatably supported and which has a radial groove formed therein. The rotor possesses a bore having a detonator inserted therein, and in a peripheral region incorporates a grooves which extends along a plane which is axially offset relative to the radial groove, and with a spreadably or expandable restraining medium being inserted into the groove. The restraining medium releases the rotor which is retained in its secured position only subsequent to the firing of the projectile through the securing element which is spreadable and axially displaceable under the effect of axial and spin forces and which allows the rotor, after its release, to be pivoted in conjunction with the detonator into the armed position.

The combustion chamber which connects to the weapon barrel widens conically at a relatively flat angle, and in which the head of the differential pressure piston (injector), which is provided with overflow passageways and nozzles, has its external contour correlated with the cone of the combustion chamber. Hereby, the conically-shaped outer wall or shell surface of the injector can incorporate annular recesses, grooves or the like.

Abstract: A digitally-operating electrical appliance or equipment which is adapted to automatically handle power-supply or line frequencies of 50 Hz or 60 Hz. A full wave of the power-supply frequency is utilized for the generating of a waveform having a pulse referenced thereto. A pulse sequence which is generated independently of the power-supply frequency and is of an essentially higher frequency than the former is counted into a counter, and the content of the counter is thereafter discriminated at a threshold value of about 55 Hz.

Abstract: A barreled weapon including a forward barrel segment which is tiltable about a trunnion through the intermediary of an actuating arrangement, and additionally includes a rear barrel segment which is similarly pivotable about the trunnion whereby the barrel segments, when oriented in their coaxial position, are sealed through the utilization of a sealing ring at a joint or separating location without necessitating any axial displacement of one of the barrel segments. The weapon includes a casing which is conducted along a screwthread and wherein, in the coaxial position of the barrel segments, the actuating arrangement rotates the casing so as to cause the latter, in conjunction with the sealing ring which is arranged thereon, to axially slide over the separating location between the barrel segments.

Abstract: A guidance mechanism for a subcaliber-sized fin-stabilized practice projectile including wings or vanes which are radially fixedly arranged on the shank of the projectile.
