Title: Measuring transfer between radioactive substrate and organic particles - in appts. with second incubation chamber formed by filter
Inventor: GONON FRANCOIS
IPC: G01N33/60
Filed: 1976-08-25
Abstract: An appts. for measuring continuously the transfer between a substrate marked by a radioactive substance and an organic substance in particle form, has a ray counter beneath an incubation chamber. The bottom of the chamber is open and the counter is sepd. from it by a film preventing the passage of a liq. but permeable by beta rays. The incubation chamber has two zones. The lower is formed by a filter, the size of the pores of which is less than that of the particles towards which the transport of the substrate is to be measured. The upper zone acts as a receptacle for the radioactively marked substrate and the organic particles in their incubating environment. Where the B-ray detector is an unclosed gas counter, a film of a material impermeable to helium is fitted between the counter and the incubation chamber.

Title: Blinker circuit for AC incandescent lamp - has bimetal contacts shunted by diode that allows full and half intensity light levels
IPC: H05B37/02
Filed: 1976-09-15
Abstract: The blinker circuit, for an incandescent lamp, consists of a bimetal strip forming a switch (1) in series with the lamp and heated by a resistance (2) through which flows the lamp's current when the bimetal switch is open. The bimetal contacts are shunted by this resistance and the resistance is shunted by a capacitor (4) in parallel with a diode (3). The diode prevents the lamp from turning off completely when the bimetal contacts are open: its intensity is only reduced to half compared to the full level when the contacts are closed.
Patent FR-2333718-A1 (FR)
Title: Liq. transport container cover - has screw-on cap with aperture receiving centre of flexible pressure relief disc
IPC: B65D51/16
Filed: 1976-11-24
Abstract: The lid includes a pressure relief device by which gases or pressure can be vented, but which will not permit escape of liquid even if liquid level above that of the opening. The lid comprises a screw on cap with a central depression, and a hole in the middle. The pressure relief device is in the form of a disc, also with a central depression, placed above the lid. The disc has a central plug which is pushed through the hole, holding the assembly together elastically. The lid has vent holes through which gas can pass to a space between the two components. This space is sealed by a lip on the upper disc. If excessive pressure occurs, the disc deforms elastically lifting the lip and venting to atmosphere.

Title: Pivoting chain controlled chimney flap - locates in flue on horizontal axis offset from its centre line and regulates passage of air
IPC: F23L11/00
Filed: 1977-01-06
Abstract: The chimne-flap (1) is for installation in the flue (7) of a new or an old chimney and controls the flow of air through the flue.

The flap may be deployed to close the flue off when the fireplace is not in use. The panel (1) may be rectangular and pivots about stub-axles (2) projecting from angle irons (6). The angle irons locate on the edges perpendicular to the axle (2). Angle irons (3) with internally projecting flanges locate the other edges at closure, and locate on opposite faces of the panel. A chain (5) to a hook may be used to hold the flap (1) open, and stops (4) may limit the extent it opens.
Patent FR-2343044-A1 (FR)
Title: Conversion of coal to methane-rich gas - with methanisation distant from gasification but near consumers of reaction heat
Inventor: VAKIL HIMANSHU BACHUBHAI
IPC: C10J3/72
Filed: 1977-01-13
Abstract: Conversion of coal to synthetic natural gas of high calorific value comprises gasification to synthesis gas of medium calorific value, and methanisation. The desulphurised synthesis gas is conveyed by pipeline over a distance of 30-490 km to >=1 methaniser situated near a user of the process heat. The synthesis gas is methanised at high temp. and separate streams of methan-rich gas and high-temp. heat distributed to consumers. The reaction heat can be used in industrial plants requiring process steam, for generation of electricity and/or in boiling water reactors. Full use can be made of the methanisation heat, which is only partially used when recycled to an adjacent coal gasification plant. Increase in energy available is 15-30% of the combustion energy of the natural gas. Fluctuations in demand can be balanced by using the storage capacity of the pipeline and by use of multiple methanisers.

Title: Advance retard system for rotary fuel injector pumps - has cam ring displaced to give extended fuel delivery at low speeds
IPC: F02D1/18
Filed: 1977-05-26
Abstract: The pump plunger (14) cam ring (12) is displaced in order to vary the fuel injector timing by means of an engine speed dependent fuel lift pump pressure (19) acting on a spring loaded piston (25). The piston is moved against a returns spring force (26) only when the lift pump pressure exceeds a predetermined value. The lift pump pressure reaches the piston (25) and a connection via a restricted boring (34) in a second spring chamber (32) and the cam ring and cam ring adjuster bore (30). The pressure is insufficient at low speed to overcome the main spring (26) but overcomes the second spring (32) as pressure increases to retard the vary the injection timing.
