Title: Container opening and resealing mechanism - is accommodated inside with sharp edged base and pivoting cutter
IPC: B65D75/70
Filed: 1974-05-10
Abstract: The bag-type container is of flexible material and has a cutting mechanism mounted inside it, with a base portion for holding in one hand, and on which a cutting portion held in the other hand pivots. Both portions have cutting edges, so that rotation in relation to each other cuts the container open. The two can be attached together by a link extending downwards from the base and to the opposite edge, each having straight edges near each other so as to determine a tear-open line. The container can be of plastic, folded and sealed in the transverse direction. The opening mechanism can have a sharp-edged feathered flange with a number of openings into which the securing plastic is poured.

Title: Multiple section partition wall - has each pivoting section attached by carriage to rail fixed on ceiling
IPC: E05D15/58
Filed: 1974-09-16
Abstract: The partition wall sections are positioned side by side, and each one is attached to a roller-carriage, placed in the section's centre. The support or carriage enables the section to be moved along a rail fixed to the ceiling, and to be pivoted across the rail when it reaches its positioning point. A guide-piece inserted in the rail a little way from the support is detached when the partition pivots. One of the sides of the rail has an aperture, in the pivot area, and one of the cheeks of the rail has a gap enabling the guide-piece to go through. A stop-piece on or in the rail prevents the partition wall from moving out of position.
Patent FR-2310026-A1 (FR)
Title: Oscillator synchronised to external signal - which arrives at TV receiver via cable distribution network and is ineffective during signal absence
Inventor: COURCELAUD JACQUES
IPC: H03L7/24
Filed: 1974-11-22
Abstract: The synchronising circuit synchronises a capacitively coupled oscillator to an external signal. Such an oscillator might be incorporated into a circuit located between a television receiver and its cable distribution network. An amplifying transistor is connected by its collator/emitter path into the main capacitive loop of the oscillator and the sync. signal is applied to its base. The incorporation of this transistor allows a large capture range without introducing appreciable distortion into the oscillator output signal. Furthermore in the absence of a synchronisation signal the amount of oscillation signal injected into the cable networkis negligible.

Title: Nuclear reactor fuelled by eutectic salt mixture - with integral primary cooling system
Inventor: GRENON MICHEL
IPC: G21C1/00
Filed: 1974-12-24
Abstract: In a nuclear reactor fuelled by molten salt. The reactor vessel is a double-walled vessel housing the reactor core of graphite suitably pierced with channels for the circulation of the molten fissile material, e.g. uranium fluoride/lithium fluoride eutectic mixt. Fissile material circulates upwards through the core and out via passages to a series of heat exchanger which discharge cooled liquid via outlet channels to a series of circulating pumps which return the liquid back to the core. Heat is extracted by pumping a suitable coolant through heat exchangers. As the corrosive props. of the fissile material are greatest at high temp., the path of hot material from the reactor core to the heat exchangers, is therefore kept as short as possible. The volume of fissile material in circulation is minimised; corrosion is kept to a minimum by the location of primary cooling equipment inside the reactor vessel.
Patent FR-2346763-A1 (FR)
Title: Mixing valve for hot and cold water - utilises pressure differential diaphragm regulators supplying adjustable ball orifice unit (BE300776)
IPC: G05D11/16
Filed: 1975-01-31
Abstract: A flow mixing regulator provides a constant temperature for domestic water by mixing a hot water supply with the cold water supply. The unit maintains the temperature for a variation in the supply pressure conditions and assumes a fixed temperature source. The hot and cold supplies are controlled by differential pressure regulating stages to supply water to a ball orifice valve that may be manually set to provide temperature control of outlet water. Operation of a poppet valve connects cold water to a spring diaphragm valve to set the pressure level to the underside of both diaphragms of the regulating valves. Any variations in supply pressure generates opening or closing of the regulator poppets to maintain constant flow conditions to output. An 'off' valve may be operated to unload the regulators and cease the mixture control action.

Title: Solar radiation collector with absorbing surface - has layer of sensitive material which changes colour according to temperature
IPC: C09D5/32
Filed: 1975-11-14
Abstract: The solar radiation collector has an outer plate (5) which forms the radiation absorbing surface and a back plate (7) which leaves a space (6) between itself and the front plate for the circulation of water to be heated. The back of the collector is well insulated (8). On top of the absorption surface (5) there is a layer (4) of a temperature sensitive material in front of which there is a glass plate (2) leaving an air gap (3) between itself and the temperature sensitive layer. This layer is of an absorbing colour at low temperatures and changes to a colour which is less absorbing and more reflecting when the temperature reaches the maximum permissible level. This prevents overheating at times of low hot water demand.

IPC: G01G19/08
Filed: 1976-05-11
Abstract: The arrangement of a weighing valve (5) on the link suspension of a rail vehicle serves for determining the axle load, especially in two-axle rail vehicles. The link is pivoted on a transverse pin (12) supported on a spring bracket (2) with radial play. A clamp (6), in which the weighing valve (5) with vertical measuring axis is suppported below the transverse pin (12), which valve is braced on the other side against a cross sleeve of the bracket enclosing the transverse pin (12) with play, is pivoted on the transverse pin (12). The clamp (6) is provided with arms projecting horizontally on the side remote from the link, which arms are supported on a continuation (14) of the spring bracket (2) so that they can swivel about a transverse pin (13). The arrangement ensures that the weighing valve always measures the force corresponding precisely to the vehicle weight or the loading of the respective vehicle axle. Owing to the small space required it can be provided on all vehicles without the need to undertake major modifications.
