Title: Appts. for simulating firing behaviour of projectiles from aircraft - generates light and smoke effects in conjunction with projectile firing noise
Inventor: DAMANN FRANZ JOSEF
IPC: F41A33/04
Filed: 1973-09-13
Abstract: The simulation of firing of a projectile from an aircraft represents the correct light, smoke and noise effect specific to a given projectile or a rocket. The fire is simulated by spraying liquid medium which is mixed with a dye for colouring and which is simultaneously mixed with a specific smoke. The sprayed or ejected medium is illuminated by a high power light source for a specific period. An electric noise generator produces simultaneously the typical firing noise of a rocket with correct frequency loudness and decay of noise. A housing accommodates a compressed air cylinder which is connected by a solenoid valve to a tank for water and to another tank which contains smoke or dye. Both media are passed through nozzles into the atmosphere and they form the imitated smoke and fire. The intensity mixing ratio and duration are determined by a programmable control electronic system. This apparatus is used on aircraft for training purposes for ground observers.

Title: Flow shut off or discharge valve for water pipes - has automatic movement to open or shut position when released in intermediate position
Inventor: BAST SIEGFRIED
IPC: F16K31/528
Filed: 1974-03-04
Abstract: The valve has simple construction, small distance of hand movement, and safe retention in the fully open and fully closed positions. A mechanism automatically moves the valve shut off device to the open or closed position, if it is left in an intermediate position.
