Title: Partly casing electrical component - by standing lower part of component, e.g. coil, vertically in trough, encapsulating in cast resin and cooling resin to set
Inventor: LORENZEN KLAUS
IPC: H01G2/06
Filed: 1990-09-19
Abstract: At least the base part of a casing is produced on electrical components, coils, toroidal core windings, transformers, capacitors etc.; in the process the lower part only of the component is inserted into a bath with open top and a set volume of a low viscosity resin is poured into the bath; when the resin has cooled the component with the part cast on to it is withdrawn upwards out of the bath. ADVANTAGE - The process enables various types of electrical component, and particularly those which are more difficult to manipulate, to be securely attached to PCBs whilst at the same time ensuring that most of the surface of the component remains uncoated for heat dissipation. In an example, an annular core winding (10) with base is produced by placing the basic coil so that it stands vertically in the bath of suitable shape. Suitable connecting pins (15a, 15b) with appropriate ends to join the winding (10) are preferably positioned beforehand e.g. having top loops (16) for taking wires (17) pressed together with the wire. The base (19) of the coil is thus cast in position, which is preferably heated already. The resin penetrates all interstices in the coil, especially if under moderate pressure, e.g. from a gear pump.

Patent DE-4108406-A1 (DE)
Title: Thyristor control circuit for alternating current supplies - utilises up-down counter and ROM look-up table to define repetitive switching sequence used to trigger thyristor
Inventor: ECKSTEIN WOLFGANG DIPL ING
IPC: G05D23/19
Filed: 1991-03-15
Abstract: A synchronisation signal is obtd. from a resistor (Rsyn) and passed to a half-wave detector (9) and a crossing point detector (11). The former detects the half-wave periodicity and passes a timing signal (Th) to a timing signal generator (10) that generates a synchronising pulse (Tsyn) which is passed via two AND gates (G1,G2) to an up/down counter (5) and to a shift register and buffer (7). The output of the up/down counter is passed via an address bus (5a) to a ROM (4) contg. a conduction sequence look-up table. Each word in the look-up table comprises a conduct/not conduct sequence, the average value of which is proportional to the up/down counter address value. The addressed word is passed to the shift register and clocked by crossing point detector impulses onto the trigger contact of an external thyristor (2) (via an amplifier (8)), thus turning the thyristor on and off in proportion to the value stored on the up/down counter. If desired supply voltage (c) is greater than the actual supply voltage (d) an amplifier (K) enables the first gate (G1), allowing the synchronising pulses to increase the value stored on the up/down counter, thereby reducing the average thyristor conduction time, whereas if the desired supply voltage (c) is less than the actual supply voltage (d), the amplifier enables the second gate (G2) via an inverter (G4), thereby reducing the value stored on the up/down counter, reducing the average thyristor conduction time. USE/ADVANTAGE - For electric heating. Inclusion of up/down counter permits finely graduated adjustments to be made to output power setting, reducing adjustment response time and improving accuracy.
