Abstract: The present invention relates to a method and a device for producing perforated propellant in the geometric form of block, stick, slab, cylindrical or tubular propellant (2) with high charge density and high progressivity. The propellant as claimed in the present invention is characterised by a large number of perforations, densely and evenly distributed over the entire propellant segments, made by perforation members (6) that are pressed down into the propellant. The perforations are thereby made in a plurality of steps with a predetermined step feed between each perforation operation. The device as claimed in the present invention also comprises a mobile pin die (5) away from but facing the feed path (1) for the propellant (2), and containing at least one row of pins for perforation of the propellant whereby each such row of pins comprises the number of pins (6) required to cover the complete width of the propellant segment across its direction of advance. Between each perforation operation the propellant is step fed by a step feed device (15) a distance equivalent to the distance between two desired perforations multiplied by the number of rows of pins arranged across the direction of advance of the propellant. Additionally, in the propellant as claimed in the present invention the distance between two burning surfaces of the propellant shall be equal to double the desired burning length (2b).

Abstract: The invention relates to trigger units for initiating pyrotechnic elements which usually consist of a switch and control unit, ignition means and an ignition charge body. Said switch and control element is triggered by way of an electric coupling via a line in order to initiate ignition. The line for the electric coupling and the dimensions of the switch and control element which are usually accommodated in an IC housing complicate the design and the automatic assembly of the trigger units. According to the invention, the switch and control element (1) is surrounded by a first shell (2). Said first shell (2) is connected to a second shell (1) which contains the ignition charge body (23). The invention is further characterized in that the ignition means (19) dip into said second shell (21).

Abstract: A marine drive for a boat includes a torque converter between the engine and propulsion unit. The torque converter has a slip condition in which a torque magnifying, fluid coupling is interposed between the engine and the propulsion unit. The slip of the torque converter enhances acceleration of the boat by permitting rapid increases in engine speed and power through relieving propeller loading of the engine. The torque converter has a lock-up condition in which the input and output shafts are directly and mechanically coupled together to provide highly efficient, sustained speed operation of the boat. A control operates the torque converter between the slip and lock-up conditions. This control may be obtained responsive to operating conditions in the engine or torque converter, such as engine speed, torque converter slip, throttle position, intake manifold vacuum, and engine ignition advance. The torque converter may be placed in the slip condition at low speeds for slow speed trolling and during the shifting of direction controlling gears in the marine drive.

Abstract: A low Q ring laser gyro-dither motor assembly which is responsive to a wide range of frequency components of a drive signal having a randomly varying frequency such that the dither imparted to the gyro is frequency modulated by the drive. The frequency modulated dither varies the lock-in rate of the gyro as a function of the random drive signal to eliminate errors in the gyro output due to lock-in. The drive signal may be random in frequency only or random in both frequency and amplitude to provide the frequency modulation. Fixed frequency modulation may also be employed. The low Q assembly need not be driven at the natural frequency thereof so that a common drive circuit may be employed for a plurality of low Q gyro-dither motor assemblies forming an instrument cluster.

Abstract: A fuel assembly has a bundle of elongated fuel rods disposed in a side-by-side relationship so as to form an array of spaced fuel rods, an outer tubular flow channel surrounding the fuel rods so as to direct flow of coolant/moderator fluid along the fuel rods, a hollow water cross extending centrally through and interconnected with the outer flow channel so as to divide the channel into separate compartments and the bundle of fuel rods into a plurality of mini-bundles thereof being disposed in the respective compartments, and a plurality of spacers axially displaced along the fuel rods in each of the mini-bundles thereof. Each of the fuel rods includes an outer cladding tube with an inner clad surface and a plurality of fuel pellets contained within the tube. Each spacer is composed of a plurality of interleaved inner straps and an outer strap encompassing the inner straps. The interleaved inner straps and the outer strap have respective protrusions formed thereon and together define spacer cells into which the respective protrusions extend to maintain the fuel rods received through the spacer cells in laterally spaced relationships in respective corner, side and interior cells defined by the interleaved inner straps and the outer straps. The BWR fuel assembly includes several improvements which enhance its thermal-hydraulic performance. First, each of the fuel rods received through the corner cells of each spacer has a diametric size smaller than that of the fuel rods received through the side and interior cells of each spacer. Also, each of the protrusions in the corner cells extend a greater distance into the corner cells than the distance through which the protrusions in the side and interior cells extend into those cells, whereby increased coolant flow space is provided through the corner cells as compared to the side and interior cells so as to increase heat transfer from the corner fuel rods to the coolant. Second, perforations are formed in the outer strap at the locations of the corner and side cells of the spacer for reducing the amount of strap area adjacent the fuel rods received in the corner and side cells and thereby increasing coolant flow to the corner and side fuel rods. Third, a generally uniform poison coating, such as boron, is applied within at least a majority of the fuel rods, the poison coating being applied to either the fuel pellets or the inner clad surface of the cladding tube of each fuel rod in the majority. Additionally, a predetermined pattern of fuel enrichment is provided with respect to the fuel rods of each mini-bundle thereof which together with the uniform poison coatings within the fuel rods ensures that the peaking powers of fuel rods in the corner and side cells of the spacers are less than the peaking power of a leading one of the fuel rods in the interior cells of the spacers.
