Patent SE-8100385-L (SE)
Inventor: PETTERSSON K
IPC: F42B10/54
Filed: 1981-01-23
Abstract: A training projectile which is stabilized by its own rotation during flight is described and comprises a conical nose section (1), a cylindrical intermediate portion (2) and a tail section. The projectile is provided with aerodynamic surfaces in the form of fins (4) or grooves (8) (not shown) on the cylindrical intermediate portion (2). The fins and grooves, respectively, extend substantially radial and parallel to the symmetrical axis (5) of the projectile. The arrangement of said fins or grooves imparts a braking effect on the projectile to reduce its rotational velocity after launching so that the projectile at a specific, critical rotational speed becomes unstable and tips or tilts. This means a substantial increase of air resistance and a corresponding reduction of the projectile velocity forwards. By an appropriate adjustment of the fins (4) and grooves (8) respectively, it is possible to locate the instability just behind the target distance when training. The ballistic properties of the training projectile are maintained up to the target distance but the maximum firing range is reduced compared with the normal live ammunition. <IMAGE>

Filed: 1981-12-28
Abstract: A linkage system for actuating the variable vanes and the air bleed valve of a gas turbine engine compressor in an intermittent sequence includes a single actuator and a linkage mechanism. The latter is formed of a first actuating linkage extending to the bleed control valve, a second actuation linkage extending to the variable guide vanes, and an intermediate crank mechanism connected to the first and second actuating linkages and also to the single actuator. The linkage system is operative to convert the linear motion from the single actuator to multiplane intermittent rotational motion of the actuating linkages extending to the variable vanes and the bleed valve of the compressor. When embodied in a military aircraft, the single actuator is preferably disposed above the compressor casing so as to make it less vulnerable to enemy ground fire.

Abstract: The invention relates to a cooler for granular products, essentially consisting of a cooling reservoir, a product inlet at the top, and two grids for the discharge of granules, which grids are movable relatively to each other. In the cooling reservoir a current of air is generated by means of a blower, the cooling air being drawn in through the granule discharge grid and being passed through the cooling reservoir countercurrently relatively to the product to be cooled. The air inlet for the blower is disposed in the top part of the cooling reservoir adjacent to the granule inlet lock. Any fines present in the granular product are exhaused direct by the blower. For this purpose a controllable opening is provided in the suction tube of the blower for drawing in secondary air. The product discharge grid is of such construction that in the closed condition it is permeable to air without permitting the product to be cooled to flow out of the cooling reservoir.

Abstract: The rod-shaped aerial is formed as a modified Franklin (RTM) unit for a high frequency range, and incorporates a rod of a quarter wavelength nearest the earth plane and colinear with it is a rod of half wavelength. Both rods are connected to a phase-turning unit, and the aerial is fitted insulated by means of a fixture over the earth plane. The free end of the quarter wave rod is connected to the inner conductor of a coaxial cable, the outer conductor of which is connected to the earth plane. - The aerial and its fixture are modified so that at the feed point they are connected parallel to the aerial gap in an inductive stub located in the fixture, the length and characteristic impedance of which are so selected that its reactance coupled in parallel with that of the aerial is adjusted to the aerial cable characteristic impedance on two frequencies. One of these frequencies is close to the aerial lower limit frequency, and the other approaches that of the upper limit. (Provisional Basic advised week 84/09)(0/1)

Abstract: A diesel heater includes a combustion chamber and a fuel pump for pumping diesel fuel to the combustion chamber. An air supply device supplies combustion air to the combustion chamber. An igniter ignites the diesel fuel to generate combustion heat. A heat exchange fluid supplying device supplies fluid in heat exchange relationship with the combustion heat. A thermal sensor in contact with the heat exchange fluid generates a temperature signal related to the temperature of the heat exchange fluid. A flame detector detects an ignited diesel fuel flame and generates a flame signal in response thereto. A microprocessor includes a memory and a plurality of input/output ports wherein the input/output ports are electrically connected to the thermal sensor, the fuel pump, the heat transfer fluid supplying device, the igniter, the combustion air supply device, and the flame detector. The memory stores a normal operating sequence, a start-up sequence, and a tail start period for the start-up sequence. An input device allows the current day and current time to be entered into the microprocessor memory. The microprocessor thereafter updates the current day and current time. A lower threshold temperature for the heat exchange fluid is entered into the microprocessor memory by the input device. A start day and start time are also entered into the microprocessor memory by the input device. The microprocessor automatically initiates the start-up sequence when the heat transfer fluid falls below the lower threshold temperature or when the current day and the current time equal the start day and the start time. The microprocessor executes the normal operating sequence when the flame signal is received.
