    • The device comprises electronic means (2, 3) for querying a transmitter-receiver circuit (1) carried by a person wishing to open the said door, for recognising a predetermined code sent in reply by the said circuit and for subsequently commanding the removal of a locking pin (10) from a catch (11) of a door latch (8) forming part of the lock, and means for the activating of the electronic means (2, 3) by the said person. The said activating means (13) are designed for operating a dialogue between the said electronic means (2, 3) and the circuit (1) and the optional unlocking of the door latch (8) of the lock before the said person's action on the handle (6) causes the door to be blocked by the friction of the pin (10) in the said catch (11) of the door striker (8).
    • 该装置包括用于查询由希望打开所述门的人携带的发射机 - 接收机电路(1)的电子装置(2,3),用于识别由所述电路发送的预定代码,并随后命令删除 来自形成锁的一部分的门闩(8)的锁扣(11)的锁定销(10),以及由所述人激活电子装置(2,3)的装置。 所述激活装置(13)被设计用于在所述电子装置(2,3)和所述电路(1)之间进行对话,并且在所述人员对所述电子装置(2) 手柄(6)使门被门撞杆(8)的所述卡子(11)中的销(10)的摩擦阻挡。

    • A remote power-feeding and protection system for equipment connected by two transformers to a four-wire transmission link.The remote power-feeding and protection system and the remote power-feeding extractor protection device are intended for equipment connected by two transformers to a transmission link with two pairs of wires ensuring remote power-feeding of the fed equipment.Each transformer is connected to the two wires of one pair by two identical windings serially-connected between these two wires through a capacitor. The two pairs of wires constitute a phantom feed circuit, the two wires of a given pair being connected to the same terminal of a D.C. generator. The extraction and protection device comprises two rectifier bridges each separately connected by their inputs to a pair of wires and interconnected by their outputs in order to provide remote power feeding.
    • 用于由两个变压器连接到四线传输链路的远程供电和保护系统。 远程供电保护系统和远程供电提取器保护装置用于通过两个变压器连接到具有两对电线的传输链路的设备,确保馈送设备的远程供电。 每个变压器通过两个通过电容器串联连接在这两根导线之间的相同的绕组连接到一对的两根导线。 两对导线构成幻影馈电电路,给定对的两条导线连接到直流发电机的同一端子。 提取和保护装置包括两个整流桥,每个桥由输入端分别连接到一对导线,并通过其输出互连,以便提供远程供电。
