Title: Articles of different sizes wrapped in shrinkable sheet - selected from several rolls of different widths as desired
Inventor: KALLFASS KARL-HEINZ
IPC: B65B41/12
Filed: 1975-02-19
Abstract: A method of wrapping articles in (hot) shrinkable plastic foil is suitable for articles of variable shapes and sizes. Several rolls of sheet are kept available, each with its free end hanging down just above the conveyor which carries the articles. Before each article arrives at the wrapping station, the required sheet is lowered in front of it. The sheet is pref. dropped under gravity, until sufficient length is available to extend below the article and as far back at the seal-welding and cutting posn. It is not necessary to use excessively wide sheet for formal articles. All the sheets are ranged above the path of the articles to be wrapped, not in transversely movable frames to right or left of the path; therefore excessive width is not required for the process.

Title: Pulse generator with oscillator - has multiple resonance oscillating circuit tuned to fundamental frequency
Inventor: ZINSSER RUDOLF G
IPC: H03K12/00
Filed: 1975-03-22
Abstract: The multiple resonance oscillating circuit is tuned to the pulse repetition fundamental frequency, its second and third harmonic, and possibly to further harmonics so that a saw-tooth output voltage is generated, whose steep rising edge has a point of inflexion. The oscillating circuit is so coupled to the load, through differentiating components, that a pulse is generated at the load by the edge differentiation, whose width is equal to the edge rise time. This pulse generator can generate a train of very short, steep and powerful pulses of relatively high frequency. Powerful active elements having relatively low upper limit frequencies can therefore be used.
