Title: Furniture dowel driving and glue injecting machine - has gluing nozzle end offset rearward from dowel driver front end
IPC: B27F4/00
Filed: 1977-05-11
Abstract: In furniture component manufacture the machine is for driving in dowel plugs and spraying adjustable quantities of glue into plug holes, using nozzle and valve.

Title: Explosive practice target for airgun - simulates gun report by having detonating charge at target centre exploded by pellet
Inventor: SACHSENWEGER GERHARD
IPC: F41J5/06
Filed: 1977-05-13
Abstract: The device according to the design is for use in connection with air gun shooting practice at short distances.

Title: IC engine fuel injection nozzle - in which most of needle valve closing force is exerted by fuel
Inventor: KOPSE ODON DIPL ING
IPC: F02M61/06
Filed: 1977-06-10
Abstract: The injector has a needle valve (2) which opens against spring force. An additional force is exerted on the needle in the closing direction by the fuel which acts against a piston. When the needle valve is closed, the fuel supplied to the valve acts against a surface (23) of the valve in the opening direction. The area of this surface is larger than the area of the piston against which the fuel acts in the closing direction. The closing force on the piston acts over the entire stroke of the valve. The valve gives a throughflow area which is proportional to the rate of fuel supply.
