Title: Continuous casting mould cooling - by pumping liq metal at different temps to suit periodical casting operations
IPC: B22D27/04
Filed: 1973-12-26
Abstract: A cooled mould for use in continuous casting plants with periodical interruptions fed with a coolant kept in two separate reservoirs at different temps. A liq. metal (an eutectic Na -K alloy) is cooled in one reservoir by an internal cooling coil, and heated to 400 degrees C in another by external heating coils.

Title: Coal mining machine for rise steep seams - guide hinged to sled by adapter giving two articulations
IPC: E21C27/00
Filed: 1974-03-28
Abstract: Coalmining machine for rise faces in (semi) steep seams is guided along the conveyor at right angles to this by means of a sled travelling the conveyor for this purpose. The machine guide is linked to the sled through a hinged adapter member which allows articulation round an axis parallel to the conveyor and/or at right angles to this and can be locked in adjusted settings. It is preferable for the guide to be mounted on a cross-conveyor which enables the machine to travel along in both directions. The preferably L-shaped sled involved in the system should have a longer leg guided on the face conveyor at the face and a short leg which is hinged to the adapter round an axis lying parallel to the main face conveyor.
Patent FR-2266653-A1 (FR)
Title: Coating spiral metal tube with e.g. plastic sheath by extrusion - as tube passes between axially aligned support drums
IPC: B21C47/26
Filed: 1974-04-04
Abstract: A small bore steel tube wound into a spiral advances along a spiral path around a feed drum and then onto a receptor drum which is spaced from and axially aligned with the feed drum. During its passage between the feed drum and the receptor drum the tube is guided by pulleys and guide rolls which widen the spacing between adjacent turns of the spiral to allow the tube to pass through e.g. an extrusion head which applied e.g. a plastic (e.g. polyethylene polypropylene, PVC) sheath around the tube. The spiral tube is used in central heating arrangements. Conventionally the tube is coated whilst straight, thereby providing for the possibility of damaging the coating during winding into a spiral, and precluding subsequent heat treatment of the spiral tube because of the risk of melting the coating.

IPC: B21B1/16
Filed: 1974-11-14
Abstract: Process for rolling hoop iron or flat steel strip uses the continuous cold rolling of hot-rolled around wire rod fed from a coil through rollers for mechanical descaling, and then through a universal rolling until (I) followed by a rolling mill (II) rotating a higher speed than mill (I) to stretch the strip during its formation and also to preheat the strip, which is immediately annealed to profit from the preheating; the strip then passes through a third rolling mill and is sheared to a variable length depending upon the purpose for which the strip is required. The pref. plant includes a double stool uncoiler and a device ensuring a constant strip speed through the annealing furnace, which is followed by shears. Method is simple and inexpensive for mfg. cold rolled flat strip, where the heat produced in rolling reduces the energy requirement in the annealing furnace.

Title: Machine for generating power from wind or water - has moving blades with uniform angle of incidence over whole length
IPC: F03D5/02
Filed: 1975-05-23
Abstract: The machine for generating power consists of a large number of blades with each end attached to a chain or flexible belt (E).

The power is transmitted from the lower roller (B2) by a belt drive to an electric generator (F). The idean can be developed by increasing the number of rollers and placing one roller at the edge of a polygonal prism. One endless belt with blades passes around all the rollers.

Title: Offset disc butterfly valve has lip seal - shaped to give increased sealing action through line pressure from either side
IPC: F16K5/00
Filed: 1975-11-27
Abstract: The valve comprises a tubular housing with pivoting disc having an offset periphery acting in conjunction with a co-axial annular zone in the housing by means of a curved sealing element whose rim is secured to the disc or in the housing, which element has a lip which sealingly engages a surface of the housing or disc respectively, the arrangement being such that increased live pressure on the concave side of the element increases the sealing force. As seen in radial section, the sealing element can swivel about its anchoring in the direction of its concave side such that its envelope curve includes the annular sealing zone, whilst its shape and/or material is such that pressure on the convex side causes a sealing force which is greater than the force tending to lift the lip off its sealing surface.

Title: Pressure refining - of chemically delignified and defibrillated cellulose pulp
IPC: D21D1/00
Filed: 1975-12-18
Abstract: Production of cellulose pulps, particularly for papermaking having improved properties by subjecting hot, at least partly and preferably chemically, delignified and defibrillated pulp of high concentration to the mechanical action of two working surfaces mutually displaced in relative motion in a closed chamber at superatmospheric steam pressure, for the compression, bending and rolling of the individual fibres without significant breakage of these. Extends the known advantages of pressure refining to defibrillated partly or wholly delignified cellulose pulps, so that a reduction in the content of long fibre material and therefore a cost reduction in the manufacture of paper is secured, while giving a product with improved properties e.g. tear strength, tensile energy absorption (in the wet section) etc.

Title: Air fuel mixture regulator system - has ignition timing additionally adjusted to air fuel ratio
IPC: F02P5/155
Filed: 1976-03-11
Abstract: In the addition to 2417187, a signal is gained from the crankshaft speed variations at revolution synchronised time intervals to alter the air mixture ratio in order to permit the engine to run on a weak air fuel mixture, to reduce the toxic content of the exhaust emission. The signals are now used as a measure to indicate engine fluctuations and compared with a required value corresponding to even running. The difference in signal values is then applied to an ignition timing advance-retard adjuster or fed to an electronic ignition circuit.
