Patent FR-2008395-A1 (FR)
Title: Purification and recovery of basic vapours from - ammonium nitrate production plate
IPC: C01C1/18
Filed: 1969-05-13
Abstract: Ammonium nitrate is removed from the condensed vapours by means of anionic and cationic selective electrodialysis membranes. In the electrodialysis process the 'concentrated' circuit comprises an acid soln. contng. 65-80% ammonium nitrate, the dilute circuit is the condensed vapour and the operating temp. is 40-60 degrees C. The acid soln. may be obtained in the neutralisation plant by neutralising nitric acid (47-48%, 50-53% or 56%) with gaseous NH3. Ammonium nitrate is recovered from the 'concentrated' circuit by passing to the first stage of an evaporator after pre-heating. Vapours contng. 1,500-20,000 mg./l ammonium nitrate may be purified to a content of 300-500 mg./l.

Title: Nuclear reactor core passive protection system - esp for fast neutron reactor based on fall under gravity of fuel melted by local overheating
IPC: G21C9/02
Filed: 1972-12-20
Abstract: At the bottom of each of a number of separate safety rods which are substituted in the core for normal fuel rods, is a crucible section of refractory material above which is an expansion chamber for fission product gasses with at its top a ring diaphragm supporting a plug, with small central bore, of refractory material.

Abstract: The indicator shows whether a battery is being charged with a voltage lower or higher to a nominal voltage. It has four operational amplifiers (A1, A2, A3, A4), part of an integrated circuit. The input to the first amplifier (A1) is obtained from the voltage drop of a diode (D1) to give a voltage reference. This first amplifier (A4) is also polarised by a fourth amplifier (A4). Two other amplifiers (A2, A3) have inputs from the voltage reference and from the supply voltage (VA) and are connected to the output of the first amplifier (A1) through adjustable resistors (R2, R3). These two amplifiers (A2, A3) make up comparators which detect min. and max. thresholds of the charge voltage. These thresholds are indicated by an electroluminescent diode (D2).

Title: Vehicle direction indicator flasher unit - has mechanical make and break assembly using springs and hot wire filament
IPC: B60Q1/38
Filed: 1975-04-25
Abstract: The flasher mechanism has a bistable assembly of a sprung metal strip (T1), a coil spring and a sprung arm (B, Ra) which is cantilevered about an axis (A). Oscillation between the two positions is caused by a hot wire (F) which expands and contracts as the electrical current through it flows or is interrupted, as the metal strip (T1) springs to its alternative position and back. The electrical make and break action is relayed to the indicator lamps by the switch (5) and either conducting (C3, C4 or C1, C2 closed) or non conducting (C1, C2 open; C3, C5 closed), contacts, causing the lamps to flash.

IPC: A47L15/42
Filed: 1975-12-18
Abstract: 1464070 Dishwashers ELECTROLUX AB 3 Dec 1975 [19 Dec 1974 5 Nov 1975] 49644/75 Heading A4F [Also in Division E2] In a dish-washing machine having a door 11, 12 operable by a pull on a finger grip 34, access to the grip is normally prevented by a shielding device 28, the device being movable inwardly to allow such access and when moved operating a switch 26 to disconnect electric supply to the motor of a water pump feeding spray nozzles so that the spraying is stopped before the door is opened. As shown the door has a pivotable latch 13 engageable with a lug 20 on the machine, the latch being pivotally connected to an arm 24. When the shielding device 28 is pivoted anti-clockwise (into the position shown in Fig. 2), its limb 31 disengages from a projection 27 of the switch 26 to stop the pump. This allows access to the grip 34 which when pulled opens the door, the latch 13 pivoting anti-clockwise and the arm 14 clockwise. A plate 35 biased by a spring 25 abuts the limb 31 and retains the device 28 in the position shown in Fig. 2 when the door is open. In a modification Figs. 4 and 5 (not shown) a slide (39) linked by an arm (36) to the device 28 prevents operation of the latch 13 until the device 28 has been moved and so prevents opening of the door, e.g. by grasping its sides, without movement of the shielding device.

Title: Spring loaded snow-plough mounted on vehicle - has spring loading pivotal halves on one link of each pair of mounting links
IPC: E01H5/06
Filed: 1976-02-27
Abstract: The snow-plough cutting edge is mounted directly on a vehicle or a bracket attached to a vehicle by means of pairs of directing members which are subject to the action of a spring directed downwards to the road being swept. One of the small links in each pair forming part of the directing members has at least two halves hinged to each other and arranged in such a way as to form a certain angle, while subjected to the return force of the spring. When the lower edge of the plough meets an obstacle of any sort, damage to the plough is avoided because the blade is able to move up and over under the action of the spring.
