Title: Card board separator between round bottles - is curved and inserted by overhead form roller set
Inventor: MUENCH KARL
IPC: B65H1/30
Filed: 1975-10-18
Abstract: A horizontal stack of corrugated cardboard strips (10) is placed on a dispenser table (11) such that the first strip is pressed against a vertical end plate (12).

Title: Generation of acoustic vibration in flowing fluid - using mechanical oscillations of an element vibrated by periodic alignments of holes in a rotor and stator
Inventor: VARLAMOV VLADIMIR MATVEEVITSCH
IPC: G10K7/04
Filed: 1977-07-06
Abstract: Acoustic vibrations are induced in a flowing liquid or gas passing through a casing which houses a rotor and a stator. An annular flange on the rotor is provided with a series of slots or holes and the stator is provided with a row of holes facing the holes on the rotor. More holes are provided on the stator than on the rotor, so that the fluid passing through the rotor passages may be periodically compressed. A ring of an elastically deformable material is mounted outside the stator to convert the compressions into mechanical oscillations which interact with the fluid to generate acoustic vibrations. Acoustic vibrations of increased intensity are produced allowing prodn. rates to be increased.

Title: Lubricant-fuel mixts. for model engines - contg. castor oil and polypropylene glycol mono-alkyl ether
Inventor: HILLE ARTUR
IPC: C10L1/02
Filed: 1977-09-14
Abstract: Liq. fuel for mode engines is mixed with a lubricant consisting of 10-90 (40)wt.% castor oil and 90-10 (60)wt.% polypropylene glycol monoalkyl ether (I). The base fuel is pref. methanol.
