Abstract: The lock (50) has a locking pin (48) with extended control element (49) and an arm (52) with extended control element (58), further an arresting lever (59) working together with extended control element (56) of arm (52). When extended element (56) of arm (52) comes to rest against step (62) of arresting lever (59) a gap (51) is created between extended control elements (49) and (48). If a continued unlocking movement of arm (52) takes place by means of handle (63), while gap (60) allows such further movement, the extended control elements (49, 48) move into engagement with their respective finger-like ends. By this movement the lock can be unlocked also by means of form locking transfer of force onto the pin (48).
Patent DE-2909762-A1 (DE)
Inventor: LAWRENCE ALAN JAMES
IPC: H04Q11/04
Filed: 1979-03-13
Abstract: The telephone exchange system includes a coupling network (10) and multiple coupling elements arranged within it. The object of the invention is to make the telephone exchange system more flexible for later expansion or other changes, by extensive decentralisation of its control devices. By assigning processors (A0 - A7; B0, B1) to one or more terminal units (12, 14, 16), decentralised control tasks can be taken out of the coupling network. Remaining control tasks in the area of the coupling network are the responsibility of control devices which are assigned to individual multiple coupling elements. This decentralisation makes it possible to use such a telephone exchange system in a versatile manner, since its size can be adapted easily to the specified requirements in each case. <IMAGE>

Title: Joining two parts via preformed solder ring - where one part is provided with convex projection so high quality joint is obtd.
Inventor: HARTMANN HORST-JOACHIM DIPL PH
IPC: H05K3/34
Filed: 1979-12-20
Abstract: One part consists of a carrier (10), which is provided with a convex projection on its joint surface. The second part (12), which is e.g. a wire with a head, is placed on the projection; and the joint is surrounded by a solder ring(13). The assembly (10,12,13) is then heated to melt the solder (13), which wets both parts (10,12) to make the joint. When the solder ring (13) melts, the non-metallic inclusions and flux residues remain outside the joint so a clean bond free from piping and segregation is obtd. The result is a much better bond than when a solder foil is used. Copper wire (12) has head (12a), with joint surface (12b) placed on a convex projection (11) in a copper sheet carrier (10). A soft solder ring (13) is placed round the joint, followed by heating in a controlled atmos. to make bond (13a).

Title: Ceramic electrically tunable capacitor - has electrode and ceramic laminated interleaved with conducting control electrode
Inventor: THOMANN HELMUT DIPL CHEM DR RE
IPC: H01G7/06
Filed: 1980-03-28
Abstract: The ceramic electrically tunable capacitor maintains the tuned value after switch off of the equipment. When manufactured, the capacitor has a definite long term value but can be electrically tuned back to another value over a certain range, this value can also be held during non-operational conditions. The capacitor is formed of several laminates (22-31) of ceramic material and between each laminate is an electrode layer (1-11). Alternate odd electrode layers (1,5,9) are connected to one (A) of the capacitor terminals and the other alternate odd layers (3,7,11) are connected to the other capacitor terminal (B) to form the complete capacitor. The even layers (2,4,6,8,10) which interleave are the control electrodes connected to a control terminal (C). The electrical potential applied to the control electrodes uses the ferro-electrical hysteresis properties of the ceramic to adjust the capacitor value. A typical value capacitor could be tuned from 6.7nF to 8.3nF by the application of 50 volts.
