Title: Igniter for fireworks has seating for fuse cord - and friction surface with flint to generate sparks
Inventor: DAVIDOVIC MIODRAG
IPC: F42B3/117
Filed: 1976-05-24
Abstract: Igniting device for fireworks which are equipped with a fuse cord treated with black powder consists of an object typically or trigger-like shape, which can be actuated by the finger and which has a friction surface; as the finger presses upon the movable part, this friction surfaces passes into an opening, into which the igniting cord has been inserted; the friction surface jams the cord in one corner of this opening and at the same time tubs across a flint, producing a line of sparks directed towards the opening. More specifically, the trigger-like article is a resilient tongue, with the friction surface on one side. In particular, it may be box-shaped, sliding into a passage of the appts. contg. the firework. Controlled ignition, can be achieved esp. in windy conditions, without risk of direct contact between a match flame and the explosive material itself.

Title: Self-priming rotary pump for milk collecting wagon - having resilient blades with sealing outer edges and closure strips pref. of PTFE
Inventor: HELMIG REINHOLD ING GRAD
IPC: F04C5/00
Filed: 1976-08-17
Abstract: Self-printing rotary pump for milk collecting wagon comprises a pump housing contg. a wheel with a star-like arrangement of resilient blades with sealing outer edges abutting against the inner wall of the housing.
