Title: Parachute for land mine dropped from air - is formed into compact ball on reaching ground
Inventor: STAMMEL GEORG
IPC: F42B10/56
Filed: 1990-04-26
Abstract: A munition such as an anti-tank land mine (11), is dropped from the air and its fall is slowed by a parachute. The parachute cap (15) is provided with radial ribs (17) of elastically deformable material. When the parachute is descending therse elastic ribs are extended by the air pressure exerted on the underside of the parachute cap so that the cap assumes the usual shape of a parachute. On reaching the ground, the pressure on the lower and upper surfaces of the parachute is equalised. The elastic ribs then contract and form the cap (15) into a compact ball which is difficult to see so that the position of the mine is not obviously indicated. USE- Anti-tank mines dropped from the air.

Title: Measuring amt. of contamination in soft solder bath - by converting sonic pulses produced in metal probe dipped into bath into electrical pulses and plotting curve of phase summation against time
Inventor: HILBIG UWE DIPL ING
IPC: G01N33/20
Filed: 1990-11-07
Abstract: Method of quantitatively and qualitatively determining the degree of metal impurity in a soft soldering bath consists of monitoring the sonic impulses emitted as an intermetallic phase grows on the surface of a solderable metal (2) which is in contact with the bath (6.1). The sonic impulses are transferred via the clamp device (2) and coupling rod (3) to a vibraiton receiver (4) which converts the pulses to electrical pulses and then transfers these to evaluation device (5) via covered cable (8). The summation of the pulses against time is plotted and the resultant curve compared with standard curves to produce an impurity value for the bath. USE/ADVANTAGE - Determines the Cu impurity in a soft solder bath. The bath can be tested in situ with any sample being removed. The test involves low technical instrument expenditure and gives high accuracy.
