Title: Bottle cap with locking rib and tearing zone - is of polypropylene with rib reversed from moulded inclination
Inventor: GUALA PIERIACOMO
IPC: B65D47/12
Filed: 1978-12-30
Abstract: Rigid polypropylene is used for the injection moulding of a cap for a bottle of the tyre having a projecting rib on its neck, beneath which an internal projection on the cap locks into place, so that the top of the cap can only be removed by breaking through a tear-off zone. The tubular section remains permanently on the bottle neck, and this section with the tear off zones and the top of the cap, together with the internal projection, which is inclined towards the opening of the tubular section, are injection moulded in one piece. When withdrawn from the mould, the internal rib is reversed in its alignment by turning it over the zone of narrow cross-section by which it is attached. Expensive and complicated moulding tools are unnecessary and the substitution of polypropylene for the conventional middle density polyethylene ensures that the cap cannot be removed without breaking through the tear off zone.

Title: Single chip TV colour decoder - operates with NTSC, PAL or secam and automatically switches its own circuits accordingly
Inventor: SUHRMANN ROBERT DIPL PHYS
IPC: H04N9/64
Filed: 1979-10-26
Abstract: A TV receiver colour decoder, constructed as a single integrated circuit, identifies whether is is being fed with NTSC, PAL or SECAM colour signals and automatically changes over its own circuits to suit. Amplitude modulated NTSA or PAL signals are previously separated from SECAM frequency modulated signals and fed into different inputs of the decoder. The decoder separates the colour synchronising signal and identifies the system from its characteristics. Controlled by line synchronising pulses, it performs whichever type of switching is required between lines. The signal is then demodulated and decoded to give the three colour signals, R,G.B. as outputs. Two quartz resonators, three LC resonant circuits and a delay line are required to be connected to the circuit.

Title: Tufting machine yarn monitor - has pivoting tensioning weight supported by yarn to make electrical contact on yarn tension change
Inventor: SCHOLZ HARTMUT
IPC: D05B51/00
Filed: 1980-04-23
Abstract: Each yarn passes over a flat, hook-shaped, pivoting tensioning weight (1). Should the yarn tension change, then the pivoting action makes it touch a contact located in front or behind to trigger a stop action and/or activate an indicator. The tensioning weight (1) is shaped from a thin metal plate, with a hook (2) for suspension. The lower edge has an L-shape, to allow the plates to overlap when swung into their extreme end positions. A slit (4) neat the rear end, angled forwards, takes the yarn (6). The pivoting axis shaft for the tensioning weight (1) has a different electrical pole from the contacts (8,9) located on either side of the component, so that the conductivity of the weight connects the contacts electrically with the suspension shaft. The design gives a yarn monitor for a tufting machine which can show the operative whether there is a yarn break or just a change in yarn tension, for rapid identification of the fault.
