Patent FR-2254684-A1 (FR)
IPC: E02B3/12
Filed: 1974-11-27
Abstract: The sealant composition comprises a mineral mixture of graduated particle size, a bituminous binder, which is present in excess, and stiffening additives. The composition is used, in particular, for the production of surface waterproofing on sloping surfaces of hydraulic engineering structures. Although considerably more binder than cavities is present in the mineral composition, the sealant composition has adequate sag resistance, as a consequence of the addition of stiffening additives, so that it does not slide off even steeply sloping surfaces. The stiffening additives used are mineral fibrous materials, wood sawdust or peat, granulated rubber or plastic or highly stiffening mineral fillers.

Title: Optical data transmission system - converts signal to optical pulse for transmission along optical fibre between units at widely differing potentials
IPC: G08C23/06

Title: Appts. for the coagulation and sepn. of blood - using hot gases in a continuous process
IPC: C07C405/00
Filed: 1976-01-07
Abstract: Appts. for the coagulation of blood or diluted blood by heat in a continuous operation, comprises a cylindrical chamber tapering at the top to a discharge nozzle which is bent slightly downwards. The blood is fed into the chamber at the bottom by means of tangentially set feed pipes. It is carried by a pump capable of a variation in flow rate or other similar means either into a chamber preheated to about 40 degrees C. or directly into the coagulation chamber when preheating is unnecessary. The combination of the movement of the blood imparted by the pump and the positioning of the feed pump produces a rotating movement in the liq. The heated gas produced outside the coagulator by a tubular burner is fed into the lower half of the coagulator by a series of jets in its wall. The jets are placed in a spiral and positioned in such a way that the blast of hot gas gives the blood a slight upward movement which ensures longer contact between the blood and the heat source. This longer contact ensures that the necessary coagulation temp. is reached throughout the lower half of the cylinder. The temp. is controlled by regulating the input flow of the blood and of the gas heat source. Coagulation and sepn. of the serum from the coagulant is attained in one continuous process without handling or mechanical operations. This results in reduced cost and simplified maintainance.

Title: Hydraulic power transmission for rail vehicles - has two interconnected gear pumps, each in fluid communication with three others
IPC: B60T8/32
Filed: 1976-02-12
Abstract: The hydraulic power transmission for a railway locomotive has an engine (1) driving a pump (3) which supplies two gear pumps (7a, 7b). the gear pumps are connected to each other so that they run at the same speed. The hydraulic fluid from each gear pump (7a, 7b) flows to a group of three gear pumps (9, 9') with each pump connected to a single wheel. If, for example, the wheel (12a) begins to spin there is a pressure drop in the line (10a). This causes an increase in the pressure difference across the gear pump (9a) which then acts as a motor and drives the other two gear pumps (9). The principle can be applied equally well to road vehicles.

Title: High gloss coating hardened during contact with smooth film - for continuous, rapid generation of high gloss coatings
Inventor: GUIGNARD MAX
IPC: B05D3/06
Filed: 1976-04-16
Abstract: Glossy coatings are continuously generated on the surface of sheet or film supports by applying a hardenable polymeric coating composition directly to the support or to a gloss flexible film and maintaining the coated face in contact with the glossy flexible film while the coating is laminated to the support layer and hardened by suitable irradiation. The glossy film is separated from the hard coated surface for re-use. Suitable for applying a glossy varnish to supports of paper, film, metallic sheet of foil etc. The contacting film generates a higher gloss than is usually obtained from coatings cast or spread with a free exposed surface. Provides a continuous short cycle polishing technique and high throughput rates (no data). The glossy film is of polyamide or polyolefin film travelling between storage and take-up reels or in a continuous loop. The covered coating is cured by electron bombardment or by UV, radiofrequency or microwave irradiation.

Title: Detector for chloride ions in small quantity in a fluid - consisting of aluminium and platinum coil electrodes and current or potential measuring appts.
IPC: G01N33/18
Filed: 1976-06-23
Abstract: Device for detecting Cl or HCl in small quantities in a fluid consists of a cell having an electrode formed from a single turn of pure Al wire and a counter electrode formed from >=1 Pl wire. When used in flowing water, the plane of the electrodes is aligned perpendicular to the direction of flow, and the Cl content is directly proportional to the current developed between teh electrodes. For measuring the Cl content of air, an electrolyte of pure water or pref. water contg. 5-6% acetic acid is provided, and the air to be tested is contacted with the electrolyte so that the electrolyte absorbs all the chlorine. The electrolyte is then flowed through the cell from one electrode to the other, and as before a current is developed proportional to the Cl content. The potential can be measured directly or amplified.

Title: Door operated switch for vehicle courtesy light - has discharging capacitor controlling transistor bias to provide delay in switching off after door closure
Inventor: REID MICHAEL CHARLES
IPC: B60Q3/02
Filed: 1977-03-30
Abstract: Delay circuits for vehicle interior or courtesy lights which are normally switched on and off by switches activated by the vehicle doors. The circuit ensures that the light remains on for a short time after the doors are closed and is integral with the light fitting. The circuit is connected in parallel with the vehicle door switches; from the live pole to ground. The delay is governed by a capacitor (16) which is discharged through a diode (18) when the switches (6) are closed. The bias on a transistor (22) in series with the lamps (4) remains such as to keep it in conduction until the capacitor charge builds up, normally taking about 7 to 10 seconds after door closure.
