Title: Temperature regulator for electrical heating - employs winding connected to thermostat on thermistor in series with heating element
IPC: G05D23/19
Filed: 1975-09-24
Abstract: Electronic heating regulators comprising triacs or thyristors cause radio electric interference and also have safety and expense problems. These problems are overcome by using a thermistor in series with the heating resistor elements as a regulator. A thermistor (1) comprising a winding (4) of wire resistant to heat is powered from a transformer (5) delivering a low voltage. The thermistor is connected in series with the heating element (2) and its winding is connected to a main supply (3). A potentiometric circuit (7) or thermostat (6) is connected to the thermistor winding in the low voltage circuit to provide heating control and to regulate heating current when actual temperature differs from demanded temperature.

The keyways are dovetailed to accept 'double-headed' dovetail keys that drop down into them. The dovetails' are sloped so that the bases cannot be pulled apart laterally. The top cover for the composite unit has posts that locate into holes inside the separate base.
Patent FR-2346883-A1 (FR)
Title: Electromechanical relay system monitoring circuit - has receiver which detects change in position of relay contacts
IPC: H02B1/24
Filed: 1976-04-02
Abstract: The system uses electromechanical relays (111, -11n) each connected to a detector (121). The detector (121) energises the relay (11,) when its contact (141) closes and deenergises the relay (111,) when the contact (14) opens. Each relay has 3 pairs of contact terminals. Two pairs (25, 26, 27, 28). are connected in parallel. When the relay (111) if deenergised the contact terminals (25, 26) are bridged by the contact (221). All other pairs of contacts are open. When the relay is energised the contact (17) closed outer terminals (18, 19). The contact (22) moves from terminals (25, 26) over to its parallel pair (27, 28). Thus the circuit (24) to the receiver (31) always remain energised except for switching lime, when a relay is energised or deenergised. The receiver is sensitive to the short interval of time when it is deenergised due to the contact changeover. The receiver thus detects the change of state of a group of relay.
Patent FR-2367683-A1 (FR)
Title: Overhead conveyor with endless carrier chain - has deflector plates to transfer goods from one side of wall to opposite side
IPC: B65G43/00
Filed: 1976-10-15
Abstract: The overhead conveyor includes a conveyor chain which is located by two drive sprocket wheels. The sprocket wheels are on top of two pillars which stand in line and form part of a wall. Guide panels with integral support tracks for the conveyor chain are attached to vertical rails on the pillars. Equally spaced attachments on the conveyor chain are used to transfer articles from one side of the wall to the other. Fixed sensor arams are located where the conveyor loads move through a hole in the wall. Thus a misplaced load hits the sensor arm which then will operate a switch that stops the conveyor drive.
Patent FR-2367185-A1 (FR)
Title: Rotary machine working as motor or pump - has four meshing rotors each with elliptical cross section twisted along length into helical path
IPC: F01C1/28
Filed: 1976-10-11
Abstract: The machine has four cylindrical rotors mounted on parallel axis. The cross section of each rotor has the shape of an elliptical lobe and this runs as a helix along the length of the rotor. The four rotors mesh together leaving a space between them whose volume depends on the directions of the axes of the four ellipses. This varies along the common length of the rotors and as the rotors turn the position of any particular volume moves along axially. In this way a variable volume working chamber is formed. It can be used as an internal combustion engine, as a hydraulic motor, as a compressor or as a pump.

Title: Induction heating domestic cooking system - gives independent variable heating of several cooking pots by adjusting degree of coupling
Inventor: GRANDJEAN DANIEL
IPC: H05B6/06
Filed: 1976-12-10
Abstract: The thyristors of each pair of opposed diagonal switches are triggered by means of a control circuit. This is in order to achieve total energy recuperation so as to permit regulation of the cooking temperature by respective coupling variations between the inductors and the metallic bases of working pots (90). The input of the control circuit are supplied from two transformers having primary windings in series with diodes. The transformers secondary windings receive signals during the second half periods of each oscillation period from a resonating load (7) or (8). The transformers or the control circuit supply pulse with approximately coincide with the end of each second half wave of resonant current fed from one of the switch pairs. The pulses supply a trigger circuit for the thyristors of the other switch pair or vice versa.

IPC: H01M10/12
Filed: 1977-09-20
Abstract: The storage element for electrical energy, for example a lead-acid accumulator, is equipped with positive and negative plates. These plates (1) are assembled such that they lie in vertical planes. The first conductors (3), which are connected to the active material, are horizontal. Vertical metal busbars (5) are used as internal current conductors. They extend from the top end of the storage element downwards along the vertical edges of the plates (1) at a distance therefrom. Each busbar (5) has a number of lateral connections (6) at different heights, so that each plate (1) makes contact, by means of the lateral connections (6), with the busbar (5) associated with it at specific points (x, y) which are distributed over the height of the plate (1). The lateral connections (6) extend over the width of a plate group in the horizontal in such a manner that a plurality of plates (1) of the same polarity are electrically connected at different points at the same height. As a result of its considerably internal resistance, this storage element represents a considerable improvement when discharging at high current intensities.
