Title: Determination of spectrograph exposure - is obtained in seconds or photons using photomultiplier as reference to control exposure
Inventor: BONNE ROGER
IPC: G05D25/02
Filed: 1975-02-21
Abstract: Composition of metallic alloy of the cathode of a discharge tube is determined by analysis of the luminous energy spectrum emitted by the tube. Emitted energy is checked using a photomultiplier as a reference to permit programming of exposure in time or in number of photons received by the photographic plate in the spectrograph. A luminous beam (4) from an electroluminous source (2) passes through an adjustable diaphragm (6). Part of the beam is reflected by a mirror (8) towards variable slits (12) and blanking disc (14) to a reference photomultiplier (16). The main beam (18) passes through variable slits (20) and blanking disc (22) to the spectrograph (24). Electronic circuits determine exposure time expressed in either seconds or photons to control the exposure diaphragm.

Title: Conveyor control for carriers in article store - has switch and article counter with actuators on carriers and reset mechanism
IPC: B65G1/127
Filed: 1976-09-21
Abstract: The control system is for the movement of carriers in an article store, via a conveyor along a path to an access position. Each carrier has a number, which represents the actual value at the access position. Each carrier (11) has a first counter actuator (33) to produce a position signal when the actuating member passes the switch (35). A counter is coupled to the switch to connect the position signals. A start and stop control is coupled to the switch, the counter, and an input feed. When a position signal is issued, and ther is a difference between the actual value registered in the counter, and the index value fed into the input unit, the start-stop control actuates the conveyor. When the values agree, it stops the conveyor. A second actuator (37) produces a signal, when it passes a second switch (39), with a connected reset element for the counter.
