Title: Acoustic switching arrangement
Inventor: GREENWOOD MICHAEL JOHN
IPC: G01S3/803
Filed: 1982-11-02
Abstract: An acoustic switching arrangement, suitable for use in a proximity fuze of a land mine capable of detonating in response to overflying helicopters, comprises (Fig. 2) a group 14 of directional microphones A, B, C, and D arranged with axes of maximum sensitivity mutually divergent e.g. in a horizontal plane. With four microphones in quadrature as shown a source detected initially by one thereafter designated as leading microphone say A. When the source moves closer and produces signals in all microphones, those of the leading microphone (A) and trailing (its opposite) microphone B are compared (32, 33) and when the difference between them is sufficiently small the source is considered to be at its closest point of approach. At that time the signals from the microphones C and D are compared (30, 31) and if the difference between their signals is sufficiently small the source is considered within a conical switching region subtended by a vertical from the group and coinciding with the blast cone of the mine. Different numbers of microphones may be used and the occurrence of the closest point of approach may be predicted in advance. <IMAGE>

Title: Mechanically strengthened glass fibre mat and method of making the same
Inventor: PERNER HARALD
IPC: D04B1/00
Filed: 1986-09-16
Abstract: The invention relates to a mechanically strengthened glass fibre mat which is suitable for reinforcing plastic-composite materials and The aim of the invention is to provide a glass fibre mat as a reinforcing material for which is not subject to any reduction in stability, which has a low resistance to bending and therefore a high degree of contour adaptability, a variable breaking strength and bulkiness and allows accurate working methods in the production of plastic-composite materials. The object is solved according to the invention in that knitting needles are passed in a crossrow manner through a thread cluster, which consists of randomly distributed loops of a fairly large number of glassfibre threads, and the cluster is strengthened by a mesh-forming thread system. Polyester or polyamide threads may be used. The thread cluster can also be strengthened and bonded in the warp and/or weft direction with one or more previously prepared nonwoven textile fabrics or a thread assembly.
