Title: Diode bridge opto-coupler line signalling detector - identifies current direction and isolates telephone exchange from line interference
Inventor: EMDE KURT LOTHAR DIPL ING
IPC: H04M7/00
Filed: 1979-03-20
Abstract: Loop current signalling over a line (a b) between telephone exchanges is detected by opto-couplers (La, Lb) in a diode bridge (D) whose AC diagonal is connected to the line via chokes (D1). In operation, the DC diagonal of the bridge is short-circuited (K) so that one opto-coupler (La) responds to current flowing from the b-wire to the a-wire and the other (Lb) to reverse current. The opto-coupler output switches (Ka, Kb) deliver the detected signals to the exchange. Opto-couplers are used to isolate the exchange equipment from interference induced in the line and to give a faster response than relays. Non-linear circuits may be connected across them, e.g. a Zener diode to protect them against exceptionally high interference. The DC diagonal short-circuit (K) may also be provided by an opto-coupler controlled by the exchange equipment.

Title: Main connection to choke for gas discharge lamp - has temperature cut=out which cannot be replaced without destruction of terminal block
IPC: H05B41/44
Filed: 1980-02-20
Abstract: The gas discharge lamp connecting choke (1) is encased at its front end by a cover (3) under which are two connections (4,5), electrically joined to the choke (1). To supply the choke (1) and associated lamp with mains current, a two pole porcelain terminal block (6) is firmly fixed to the rail (7) on which the choke (1) is also mounted. The terminals have screw clamps and expanding springs into which the incoming feeds are inserted. A housing (12), covers one feed connection (4) and part of the choke terminal (11) so that they are normally inaccessible. Also, below this housing (12) is a temp. cut-out (13) which on assembly of the party is connected to the terminal block (6) for the feeds at one end, while the other end is formed so that when the housing (12) is pushed on, electrical connection is made between the terminal block and supply wires. This ensures that the choke (1) is disabled when a cut-out (13) is to be replaced, since the main terminal block (6) is destroyed in the process. A wire bridge cannot therefore replace the cutout without this destruction taking place.
