IPC: A23L27/12
Filed: 1983-02-16
Abstract: Useful products are recovered from citrus peel waste by extraction with a non-aqs. water muscible solvent to leave a product high in cellulose and pectin.

Title: Structure of a thyristor with an internal ignition and its use in the realization of a bidirectional device.
IPC: H01L29/74
Filed: 1983-11-25
Abstract: This thyristor has a very much reduced sensitivity to parasitic triggering in the non-conducting state. It consists of a first emitter region (5), a first inhibit base region (3) adjacent to the first emitter region, a second main base region (2) and a second emitter region (4). The first emitter region is divided into several primary regions (5) which are electrically connected together through cathode contacts (6). The first base region (3) is divided into several regions connected electrically together by inhibit gate contacts (7). The latter contacts are connected to the cathode contacts (6) through a switch (9) enabling a short circuit between the inhibit gate and the cathode to be created so as to inhibit the self-firing capability of the thyristor. The thickness and doping of the base and emitter regions are chosen so that the thyristor is self-firing at normal ambient temperatures through the capacitive current alone when the alternating supply voltage falls to zero.
