Patent FR-2268715-A1 (FR)
Title: Package for refrigeration circuit filters - has edges of sheet folded over filters welded under vacuum
IPC: B65D81/20
Filed: 1975-04-23
Abstract: Each filter comprises a long cylinder with its diameter reduced at both ends. These are placed, side by side, in any number required to make a convenient package. Both sides of the package are formed by one sheet of a composite material, made from an outer layer of aluminium foil with an inner layer of heat weldable plastic, folded over to enclose the filters. Both sides are welded together over a wide area around the edges to form a flange. A vacuum operation excludes all air and moisture, this state being maintained by the impermeable nature of the packaging material.

Title: Tractor-towed mower attachment - has two counter-rotating rotors on vertical axles; with discharge channel pivot-mounted on a fan
IPC: A01D43/077
Filed: 1975-05-27
Abstract: The two rotors are driven by two belt pulleys which cross over each other and each run over a vertical axle. At the bottom end of the vertical axles are radially-positioned blades. Coaxially, a cylinder is positioned on the axles, and rotates with the blades, and brings the plants between the cylinders. Beneath the blades is a stationary disc beyond the front edge of which project the blades. The disc has a hole tapering in the direction of rotation, at the end of which is a slanting edge which cuts off the plants with the blades. Behind the rotors are inlet openings for the discharge channel taking the cut-up crop to a trailer. The channel contains a fan. The frame consists of two sections hinged by a horizontal axle.

Title: Enzymatic ethanol assay in body fluids - by using amino-propane-1,3-diol as buffer and trapping agent
IPC: C12Q1/32
Filed: 1975-10-15
Abstract: A compsn. for determining the ethanol content of body fluids consists of (i) the enzyme alcohol dehydrogenase, (ii) the coenzyme nicotinamide adenine di-nucleotide (iii) a buffer/acetaldehyde trapping agent selected from 2-amino-2-methyl-1,3-propanediol (I), 2-amino-2-hydroxymethyl-1,3-propanediol (II) and their mits, and (iv)an acid in sufficient amt. to lower the p H of an aqueous soln. of the mixt. to within the range 8.8-9.2, the mixt. being free of any other acetaldehyde trapping agent. The compsn. is useful for enzymatic assay of ethanol partic, in body fluids such as saliva, serum, and urine, the advantage being that a single chemical compound acts simultaneously as a buffer and as a trapping agent for one of the products of the enzymatic reaction.
Patent FR-2334485-A1 (FR)
Title: Hot metallic coil insert for fusion bonding thermoplastics - esp. to join acrylic-polyolefin components for car lamps
IPC: B29D11/00
Filed: 1975-12-11
Abstract: Two pieces of (dissimilar) thermoplastic material are bonded by trapping a hollow metallic profile between the component faces so that the materials are mechanically keyed across a fusion joint interface. The metallic profile acts as the heating element to melt the adjacent material until the component edges can be pushed together while enveloping the element in the interface. Used esp. for jointing a PMMA lens for an automobile rear light to a lamp body made of different (cheaper) material, viz. polypropylene. The mechanical link enhances the strength of joints between materials of poor weld compatibility, e.g. crystalline and amorphous materials. The interfacial key is not exposed on the surface of the assembled components.

Title: Manual volumetric dispenser for powders, granules, liquids etc. - partic. for medicaments or foodstuffs such as spices, flavourings and dressings
IPC: G01F11/16
Filed: 1977-02-11
Abstract: The dispenser comprises a hollow cylinder contg. an axially displaceable plunger returnable by spring loading after delivery. The cylinder comprises two axially-aligned, end-to-end sections detachably fixed together. At opposite ends of the cylinder, one section presents an axial discharge nozzle while the other section has an axial passage for a plunger actuating button at one end of an axial rod. The plunger at the other end of the rod is made up of inner and outer collars axially spaced by an annular channel contg. a coaxial helical screw thread around the rod in the channel. As the plunger passes through the nozzle, the channel carries a measure of fluid from the cylinder. At the button end of the rod, a helical groove in the button engages a peg fixed in the cylinder passage. This serves to turn the rod and plunger on their acis when axially displaced. The outer collar and screw section of the plunger is exchangeable to alter the delivery calibration of the plunger. When empty, the nozzle section of the cylinder is detached to be refilled or renewed.

Patent FR-2347554-A1 (FR)
IPC: F04D29/70
Filed: 1977-03-29
Abstract: The apparatus is suitable in particular for purifying fibre-fly-containing air in textile machine rooms. The air is extracted by a fan and the fibre fly contained in the suction stream is separated off on a screen (8). The screen (8) rotates together with the impeller (2) of the fan, as a result of which the fibre fly separated off there is ejected sideways into collector chambers. The screen (8) covers the suction opening of a suction funnel (7). This suction funnel (7) is arranged on the impeller (2). Between the impeller (2) and a housing partition surrounding the impeller (2) is a gap (10). In order that no fibre-fly-laden air is sucked in through this gap, the space behind the gap (10) is the pressure chamber (4) of the fan.

Patent FR-2367182-A1 (FR)
IPC: E06C7/16
Filed: 1977-05-18

In the horizontal position, the platform (10, 11) makes possible safe standing on the ladder (1, 2, 3) for carrying out inspection work or the like.
Patent FR-2352528-A1 (FR)
IPC: A47L15/42
Filed: 1977-05-25
Abstract: It has a rising pipe (1) which is connected to the container (not illustrated) of a dish-washing machine and in which a partition (2) is arranged, whose overflow edge (3) lies at the height of the normal level (4) of the container. An overflow channel (5) opens out into a chamber (6). Connected via nozzles (7) to this chamber (6) acting as an air trap are pressure circuits (not illustrated). When the circulation pump is inactive, the container is filled with water. When the filling level (4) is reached, the water runs over the overflow edge (3) into the chamber (6) until the normal water level (8, 8') in the overflow channel (5) has been reached. The pressure circuits then close the inlet valve. When the circulation pump starts running, the normal filling level (4) drops to the working level (9). If, for example owing to a leaking inlet valve, more water enters the container, the rising pipe (1) fills again up to the overflow edge (3) and the overflow channel (5) fills up to the extreme water level (11, 11'). The pressure circuits then switch the emptying pump on. The container edge in the door loading region can thus be placed lower without increasing the risk of leakage.
