Title: Fuze system for missiles; interchangable radomes
Inventor: MOUNTFORD JAMES HERBERT
IPC: H01Q1/42
Filed: 1982-11-06
Abstract: In a missile having a body housing both warhead and a fuze system for effecting detonation of the warhead at a predetermined desired instant, and in which the fuze system includes target proximity sensing apparatus (5) of the constant look angle (corresponding to direction 8' or 8'') type, provision is made to alter the look angle by supplying two or more nose assemblies adapted for alternative attachment to the body, each assembly having a window (7', 7'') of different optical characteristics.

Title: Anti-lick device for drum brake
Inventor: GERGELE JEAN
IPC: F16D65/54
Filed: 1983-01-17
Abstract: A drum brake having brake tongs 12 comprising arms 121, 122 actuated by a ram 14. Between arms 121, 122 there is arranged device 3 provided with a bore 31 and with a slideway 32 the extent "h" of which makes it possible to select the necessary play between the brake lining 131 and the drum 11. A mobile element 34 connected to one of the arms 122 of the brake tongs slides with friction in the bore 31. Slideable without friction in the slideway 32 is a stud 33 connected to the other arm 121 of the tongs 12. The friction force of the mobile element 34 in the bore 31 is greater than the force produced by the opening spring 15 of the linings 131, 132, but less than the force produced by the ram 14 which closes the linings 131, 132 on the drum 11. The travel "h" of the stud in the slideway determines the play between the linings 131, 132 and the drum 11 in order to obviate licking of the linings on the drum. In an alternative embodiment (Fig. 2, not shown) the friction force is in the arm pivot (123) and a stud (53) and slot (52) provides the travel "h". <IMAGE>

Title: Radio direction finding
Inventor: JOHANNESSEN ROLF
IPC: G01S3/46
Filed: 1983-07-07
Abstract: A receiver calculates a wanted bearing from both phase and amplitude measurements on a radio signal as received at each of a plurality of spaced apart antenna positions or antenna elements. The receiver includes computing means which determine the wanted bearing by a curve fitting and best fit process and operates on the assumption that the received signal is comprised by two coherent signals one from a source at the wanted bearing and the other being due to a reflector at a corresponding bearing, i.e. multipath signals. Whilst the computing means is of increased complexity in comparison with conventional phase only or amplitude only measurement systems, the number of antennae or of antenna positions is reduced. Any array of three elements will suffice, thus resulting in increased portability. Alternatively, greater accuracy may be obtained.

Title: Positioning of dielectric members
Inventor: MILLAR COLIN ANDERSON
IPC: G02B6/255
Filed: 1984-04-27
Abstract: The position of one dielectric member relative to another dielectric member can be assessed and adjusted with reference to an optical interference pattern. In an arrangement for positioning two optical fibres 1a, 1b, a beam 2 of coherent light illuminates the end portions of both fibres 1a, 1b so as to generate an interference pattern 40 representative of the relative positions of the fibres 1a, 1b to each other. Two orthogonal coherent light beams zA,zB (Fig. 3) may be used. By adjusting the position of one of the fibres 1a, 1b until the interference pattern 40 is of a preselected form the fibres may be brought into a particular relationship. The invention finds particular application in the alignment of optical fibres prior to jointing and in the measurement of core concentricity. <IMAGE>
