Title: Tractor-towed swathe turner and mower - has U-shaped chassis with horizontal cross-beam and two arms joined to it
IPC: A01D67/00
Filed: 1973-09-27
Abstract: The shaft for attachment to the back of a tractor has a coupling connected to a section enabling the shaft to be pivoted. The shaft curved at the back in order to make room for the machine; from which a straight section slopes down to a coupling consisting of two facing plates for attachment to the tractor. The pivot device for the shaft in relation to the chassis consists of a long pin working in conjunction with an elongated vertical pipe fixed to the back end of the shaft. A control for the pivot device consists of a piston cylinder unit one end of which is joined to an arm extending backwards which is fixed to the shaft behind the pin. The other end of the piston cylinder unit is joined to a backwards-extending plate fixed to the cross beam. The shaft is tubular and contains hydraulic fluid.

Title: Tubular swirl type flowmeter - has internal surface serrations of specified depth on swirl section and swirl vanes
IPC: G01F1/32
Filed: 1973-11-30
Abstract: A swirl-type flow meter has been designed for a wider measuring range, which can be calibrated, by making the boundary layer thickness independent of the Reynolds number. This makes it possible to determine its calibration constant for small Reynolds numbers, where its validity is maintained for large Reynolds numbers. The inside wall of the measuring tube, fitted with a swirling device with deflector vanes, has a serrated surface up to the measuring probe. The serrated surface, which is also applied to the vanes, has corrugations at right angles to the flow direction and the ratio of the serration depth to the clear diameter is 300 max.
Patent FR-2218512-A1 (FR)
IPC: F16K51/00
Filed: 1974-02-15
Abstract: This invention relates to a plugging apparatus for plugging and sealing a side opening in a conduit or vessel while the same is under a pressure other than atmospheric. In a preferred embodiment, the apparatus includes a fluid tight housing adapted to be mounted on the conduit or vessel to surround the opening. A plug carrier is movable through the housing and supports a plug assembly, the latter including a seal support, a seal expander head and a hollow cylindrical resilient seal member between the seal support and expander head. The arrangement is such that in use, the expander head moves into the resilient seal and expands the latter radially outwardly into engagement with the walls of the side opening. The expander head is imperforate so that in plugging position, it acts as a unitary fluid barrier across the interior of the seal member. By making the sealing element and the cylindrical portion of the expander head extending thereinto of sufficient length, an effective seal can be formed with the walls of a side opening in a pipeline, for example, even though such side opening may have a nominal diameter approaching the inside diameter of the pipeline.

Patent FR-2344489-A1 (FR)
Title: Treating coiled strip or wire - by alternating between two regimes to balance feed and extraction rates
IPC: B21C47/26
Filed: 1976-03-18
Abstract: A long length of flexible material e.g. metal strip is treated in a volume of liq. in a number of stages. The strip is looped and then given the shape of a helix composed of a number of coils. This helix is then continuously advanced through the volume of liq., in which the helix is immersed at least partially, by constolling the average linear rate of travel of the material inside the vol. of liq. so that it is equal to a predetermined rate of extn. of the strip outside the vol. of liq. The control of the strip speed is achieved by alternating a first regime of normal working during which the length of the material in the vol. of liq. is increased with a second adjustment regime in which the length of the strip decreased. Long lengths of flexible material e.g. metal strip, wire or tube can be treated with a fluid e.g. to pickle the material. Continuous surveillance of the strip or wire requiring the operator to control strip speed is no longer necessary.

Title: Combustion of high-content fuels - uses oxygen enriched air for complete combustion at high temp.
IPC: F23G7/00
Filed: 1976-07-07
Abstract: A fraction of non-combustible gas in the combustion air is withdrawn from the combustion zone, which may be a ballast of nitrogen and rare gases, whilst maintaining the quantity of oxygen required to ensure the same degree of combustion as previously, the quantity of heat, previously absorbed in heating this ballast thus being liberated and now being able to compensate for the cooling effect on the flame due to the excess ash, by heating the excess to the desired temperature. This provides complete combustion of fuel with increased ash contents, including solids introduced into flame, with resulting high temperature fluctuation.

Title: Liquid cooled roller for hot rolling mills - has coolant pipes which enter the ends of the roller and cool the whole roller area
Inventor: FRANTSENJUK I V
IPC: B21B39/00
Filed: 1976-08-06
Abstract: The roller is in the form of a hollow cylinder, inside which two sets of two discs are mounted. The discs support shafts which protrude from the cylinder ends and which in turn are supported on ball bearings. Ring shaped covers are mounted at the ends of the hollow cylinder which are shaped so that there is an annular gap between the inside diameter of the cover and the support shafts. Coolant inlet and outlet pipes are mounted so that they enter the cylinder through the annular gaps between the covers and the shafts. Holes round the circumference of the support discs make it possible for the coolant to flow right through the cylinder and cool the whole surface of the cylinder, thereby increasing the life of the roller.
