Title: Process for joining thermoplastic materials and metals
IPC: F16G3/10
Filed: 1981-06-04
Abstract: The invention relates to a process for joining thermoplastic materials and metals by means of a self-hardening adhesive, the adhesion taking place not only via an end abutment, but at the same time by means of a two-sided overlapping of the thermoplastic part around the metal counterpart. Preferably the groove is delimited by hook-shaped or U-shaped legs whose inner leg surfaces are inclined towards one another, so that a groove which tapers towards the groove opening is formed. In one embodiment, sealing elements are present on the inner wall parts of the hook-shaped legs which enclose the groove, which sealing elements are embedded in the adhesive on adhesive bonding. The groove or groove opening of the thermoplastic part contains sealing elements and/or forms them itself by means of one or more groove constrictions in the vicinity of the groove opening or between the groove centre and groove opening. The space formed by the groove base, sealing element and inner wall parts of the hook-shaped or U-shaped legs serves as a receptacle for an adhesive or an adhesive component.

Title: Automatic parking disc
Inventor: BECKER HEINZ
IPC: G07C1/30
Filed: 1981-06-19
Abstract: The invention is an automatic parking disc, combined with a timer, for all passenger cars. It is characterised in that   1. the parking start time is set automatically when the passenger car is parked, 2. the parking start time can be set, as desired, by means of an additional switch,   3. it serves at the same time as a timer, 4. there is the possibility of a change-over from summer time to normal time.   The difficulties of conventional parking discs are the complicated handling and inaccurate operation. The automatic parking disc does away with the hand-operated parking disc, since this is set automatically. Automation takes place by the use of the following parts: a clock, an electric motor with a gear, a parking-time dial, a switching device and a plurality of small parts. Functioning: with the ignition switched on, the circuit of the electric motor (2) is closed and the parking-time dial (11) runs in synchronism with the hour indicator (6). When the ignition key is withdrawn (upon parking), the circuit is broken and the parking-time dial stops (parking start time). The automatic parking disc can be used for equipping new passenger cars and for the retrofitting of used passenger cars.

Title: Protection wiring on the LC input filter of a power circuit for networks having voltage which returns suddenly
Inventor: DOBROS MICHAEL DIPL ING
IPC: H02M3/10
Filed: 1982-08-13
Abstract: The invention relates to protection wiring on the LC input filter of a power circuit for networks having voltage which returns suddenly, having a controllable freewheeling circuit which is connected in parallel with the inductor and, when the network voltage returns and the capacitor is discharged or partially discharged, limits the rise in the voltage on the capacitor to a value which is increased above the rated voltage by a permissible voltage fluctuation, virtually short-circuits the inductor and converts its energy content into heat, especially for supplying railway converters. In order to create protection wiring which even withstands multiple, periodically occurring power interruptions without any reaction, and furthermore manages with a simple and small construction with cheap components and increases the operational readiness of the converter, it is proposed according to the invention that the series circuit of a thyristor (5) and of an uncontrolled valve (6) be used as the freewheeling circuit and that the thyristor (5) be driven as a function of the voltage reversal on the inductor (1) during self-induction, after completion of the charging process on the capacitor (2). <IMAGE>
