Patent DE-2204239-A1 (DE)
Title: Transparent,self-adhesive films - for household use from high-pressure polyethylene,polypropylene and adhesion-improving
Inventor: RAHLFS HERBERT
IPC: C08L23/06
Filed: 1972-01-29
Abstract: A mixt. of 70-95 pts. wt. highpress. polyethylene 30-5 pts. wt. polypropylene and 0.5-5 pts. wt. EVA copolymer, edible oil and/or softener, which improve self-adhesion, is used to prepared transparent, self-adhesive films, 10-20 mu thick, by chill-roll or blown film processes. The film is used as a household film, for covering and sealing food containers. The rigidity of the film is better than that of known household films, which facilitates its processing. It can be stretched biaxially in the chill-roll process. The film is impermeable to aromas. The additives which improve the self-adhesion do not affect the transparency.

Title: Oil recovery system for compressed air motor - has cyclone separator for oil mist and oil precipitating baffle
Inventor: MINIAMI TAKESHI
IPC: F16N39/06
Filed: 1974-04-10
Abstract: The recovery system is used for recovering unused lubricating oil in compressed air motors. The lubricating oil is entrained by the compressed air flowing into the motor from an oiler in the air supply line. The entrained oil mist lubricates the motor and a large proportion of un-used oil leaves the motor with spent air. This oil is recovered by a cyclone type collector in which the oil bearing air is rotated and oil is precipitated for reuse. The oil separator in the outlet line of the motor has a cyclone collector which sets the oily air into rotation. The oil is precipitated by the baffle plate and the recovered oil flows through a channel and a valve system to the motor oiler for reuse. The valves are combined to form a unit and the oiler chamber can be connected to the atmosphere.

Title: Electronic circuit for driving an electric fence - produces pulses of a defined shape and limited amplitude and duration under all normal conditions
Inventor: SINDT HUGO
IPC: H05C1/04
Filed: 1974-08-10
Abstract: The electronic circuit is for driving a defined current in a defined pulse shape, into an electric fence, so that the peak amplitude and duration of the impulses are limited. The current pulse best suited to this consists of a very sharply increasing and decreasing pulse lasting about 1ms followed by a lower, decaying waveform over a longer period. This is applied to the fence at 1 Hz by means of a circuit incorporating two discharge capacitances (C1, C2) and a transformer (Tr). The capacitances are charged from the mains via a rectifier bridge (Br) and discharged by a thyristor (TR) which s fired once every second. The capacitance discharges through the transformer to produce the sharp initial surge whilst the second discharges directly through a diode (D5) into the fence to produce the long decaying tail of the waveform.
