Title: Manhole cover locking and release member - is projecting lug with pin for latch lifted by hooked tool to raise cover
IPC: E02D29/14
Filed: 1980-04-25
Abstract: The method of locking a manhole cover (3) in a ring shaped frame (2) embedded in the ground uses a pocket inside a rectangular extension (6) projecting from the ring, and holding a locking plug (7). The cover has a rectangular lug projecting from it which fits inside the open top of the extension resting inside it, at the bottom. This lug also has a rod shaped piece projecting radially outwards, also projecting into the interior of the extension. This lug acts as a hinge pin for the locking plug. This plug has a horizontal top plate (7) which covers the open top of the pocket, with a circular boss at one end, into which fits the hinge pin. Near the other end is a vertical flange, projecting downwards into the pocket to form a support. A tool can be inserted into a gap at the end of the top plate, to hook underneath to allow the plug to be swung upwards, lifting the edge of the cover.

Title: Remotely operated lock - uses dead latch operated by screw driven by electric motor and linked to move handle latch simultaneously
Inventor: LIPSCHUTZ PAUL
IPC: E05B59/00
Filed: 1980-09-22
Abstract: The appts. has a dead latch (1) which is moved by a screw (5) driven through a gear train (5) by an electric motor (4) which responds to a remotely sited electronic control circuit. An extension (18) on the dead latch sits behind the handle operated latch (2), preventing the latter moving while the dead latch is in the locked position. An arm (8) pivoted (9) from the dead latch (1) rests behind the handle cam (16) and when the electric motor is operated to unlock the door causes both latches withdraw together, unlocking the door. Further withdrawal brings the arm (8) into contact with a pin (14), lifting the arm in order that the handle latch springs (15) to the locked position, but remains free to be operated by the handle (17).

Patent FR-2525386-A1 (FR)
Title: Controlled switch circuit for resistive and inductive loads - has parallel connected semiconductor switch and electromagnetic relay switching in sequence across load, and zero-crossing detector
Inventor: BAHUAUD DOMINIQUE
IPC: H01H9/54
Filed: 1982-04-15
Abstract: The alternating current switch uses two switching elements in parallel across the load and either, or both, may be on or off. One element is a semiconductor switch (6), such as a triac or a thyristor, and the other (7) is an electromagnetic relay. A zero-crossing detector (4) fed by mains-derived alternating current (a) creates a train of pulses (6) which are ANDed with a control switching pulse (c) in a logic gate (9). The output (d) from the gate is fed to control and driver circuits (10,11) which drive the semi-conductor and electromagnetic switches. The semiconductor switch is fired in synchronisation with a zero-point in the alternating current cycle, thus achieving a change-over at a point of low circuit current. After the intrinsic switch-on delay, the relay is switched on in parallel. Since the current is already established, radio-frequency arcing interference at contact is eliminated. The control circuit (10) now switches the semiconductor switch off to avoid heating of this element. The semiconductor switch is brought on again just before the relay is switched off, and then off again to open the load circuit.
