Title: Projectile with a bow affixed IR seeker
Inventor: NEFF HELMUT DR
IPC: F41G7/22
Filed: 1990-10-16
Abstract: The invention relates to a projectile (10) with an IR target seeker (12-14) arranged at the nose end and means (16, 17) for correcting the projectile (10), the target seeker (12-14) exhibiting deflection devices (123) for scanning the target area. 
<??>To achieve a rosette-shaped scanning of the target area without using gyro-stabilised mechanical systems, it is proposed that the projectile (10) rotates about its longitudinal axis (10'). The target seeker (12-14) contains a laser which is followed by the deflection device (123). During the scanning process, the deflection device (123) periodically linearly deflects the laser beam in a fixed scanning plane (19) located on the axis of the projectile (10') so that a rosette-shaped scanning occurs in the target area due to the rotation of the projectile (10).

Abstract: The polyalkylene terephthalate moulding compositions according to the invention are based on a polyphosphonic acid ester, an antidripping agent and a thermoplastic having a predominantly aromatic main chain and high heat distortion resistance and are distinguished by high flame resistance. The additional use of thermoplastics having a predominantly aromatic main chain and high heat distortion resistance allows a significant reduction in the amount of phosphorus-containing compounds required to achieve UL94 V-0 classification. The moulding compositions according to the invention can be used to produce mouldings.

Abstract: PCT No. PCT/EP90/00160 Sec. 371 Date Nov. 7, 1990 Sec. 102(e) Date Nov. 7, 1990 PCT Filed Jan. 12, 1990 PCT Pub. No. WO90/10761 PCT Pub. Date Sep. 20, 1990.The surface drain has a cup-shaped drain body (14) which is securely cast into a concrete slab (10). A cylindrical inset (20) in form of a disk is fitted in the concrete slab and rotatable about the axis of the drain body. Fitted in the disk is also a rotatable cylindrical part (31) of a square frame (30) which receives a grate. When laying the tiles, the square sides of the grate frame can be set parallel to the joints of the tiles by turning the grate frame. Since the cylindrical inset (20) has an eccentric inner cylinder (24) for receiving the cylinder (31), a turning of the cylindrical inset in the concrete slab permits the square sides of the grate to coincide with the coordinates of the tile joints.

Abstract: The geared motor comprising a speed reducer of the worm screw/helical gear type and a speed reducer-driving electric motor, is characterized in that its body consists of two separate pieces (A, B) which are matingly joined and fastened to each other along an ideal vertical plane containing the axis of the motor. Between the extended parts (A', B') of the said pieces the stator (S) of the electric motor is included and firmly clamped, and the said parts are so formed that ducts (45) for cooling air to flow therethrough, are provided around the said stator. The axial shiftment of the speed reducer helical gear (4) is checked by projecting members (21, 121) integrally formed with the two pieces (A, B) constituting the speed reducer body, whereby the assembly and disassembly of the slow speed-operated shaft (2) and of the members which are associated therewith, is thus simplified. When the geared motor is employed for making a capstan device, a box (44) is provided and fastened to the speed reducer body, and contains the terminal board to which the cables for feeding electric current to the electric motor (M), the electric fan (56), and the thermostat controlling the cooling of the motor are connected, by being led through the tubes (48, 148).
