Title: Applying a coating by means of microscopic particles - electrostatically distributed
Inventor: REMY ROGER
IPC: B05B5/16
Filed: 1969-02-19
Abstract: The object to be coated is suspended in the upper part of the top container (one or two on top of each other). The division between the two containers is a mesh grid.

Patent DE-2265281-A1 (DE)
Title: Stabilised ejector release units for aircraft load - with two simultaneously activated catches linked to common explosive charge
Inventor: KLOSS HELMUT
IPC: B64D7/08
Filed: 1972-12-14
Abstract: The aircraft load or bomb is secured by two catches (4) which grip hooks (3) at both ends of the load. The catches are operated by opposing levers linked to a common cam, and braced by springs. An explosive charge operates a striker to press on the cam and release the catches. Using two sets of catches the load is securely held and does not swing in the slipstream. Some of the gases from the explosive charge are diverted through ducts from the catches. This prevents the load from snagging int he slipstream and spoiling the aim. The ejector plungers locate on stubs on the load for an even more secure mounting.

Title: Reference electrode for electrochemical systems - from graphite, and binder pressed to a contact mesh
Inventor: DREHER JUERGEN
IPC: G01N27/30
Filed: 1973-04-17
Abstract: A reference electrode for potential measurements on electrodes of fuel cells, particularly of the hydrazine hydrate type, consists of an active electrode mass of e.g. mercury oxide, graphite powder and PTFE powder, pressed to a silver wire mesh.

Title: Attenuating fine rovings by drawing and false twisting - in draw zone formed between feed and delivery assemblies of magnetically attracted magnets
Inventor: CECCHI BRUNO
IPC: D01H5/54
Filed: 1974-03-08
Abstract: A fine roving is drawn between a feed roll assembly and a draw roll assembly operating at a faster speed, in the draw zone between the roll assemblies is provided a false twisting device (pref. a pair of oppositely moving belts between which the roving is located) to impart false twist to the roving. Each roll assembly comprises a freely rotatable magnetic roll (having pref. a plastic coating) and a pair of positively driven ferro-magnetic rolls which are attracted magnetically to the magnetic roll to form nips through which the roving passes.
