Title: Water tight below ground wall construction - has precast blocks with concaved sides jointed with cement resin or bitumen to resist cracking under earth pressure
IPC: E02D5/20
Filed: 1975-10-24
Abstract: The wall is airtight and watertight and consists of precast blocks with connecting sides which have at least one concave part. In between two adjacent blocks is a circular-section sealing element which resets against the concave parts. This element can be made of any appropriate material such as pure cement, a resin, bitumen, etc., the only important factor being that the chosen product has greater strength and sealing properties than the material in which the precast blocks are covered. The joints between adjacent blocks are formed by inserting a removable pipe into the circular space formed by the concave parts of two adjacent blocks. This is filled with the selected material and the pipe is removed once it has set. Use of this method of erecting walls avoids the formation of small cracks between two adjacent blocks caused by the weight of the surrounding earth.

Title: Plasma torch for spraying metals - with metal wire or powder supplied to arc region via central tube
IPC: B05B7/22
Filed: 1975-12-23
Abstract: A plasma torch for spraying materials has a tube through which the wire or powder is supplied to the space where the plasma flame is formed, this tube passing through the cathode and opening into the region where the arc sparks. The tube runs from the point where it opens to the rear of the torch, passing through a water-cooled chamber. Coolant flows along the entire length of the chamber and then over the entire length of the tube by means of an intermediate baffle. Apart from wire or powder, gases may be introduced simultaneously or otherwise, as well as a type of radiation e.g. a laser beam. The torch can be used for flame spraying all metals including the most refractory. Owing to the high temps. it is possible to achieve a higher dispersion and consequently fine homogeneous deposits. Since the specific wt. of each particle is smaller, combustible or fusible materials can be coated without damaging them the amt. of calories supplied per unit area in a given time being smaller despite the higher temps. The torch may also be used for welding and cutting. Leakages of coolant into the arc region leading to damage of the torch are avoided by positioning seals away from hot zones.

Title: Spool driving cylinder assembly for winding machine shaft - is in halves tightened on cones by split nuts
Inventor: EXBRAYAT MICHEL
IPC: B65H54/46
Filed: 1976-02-25
Abstract: In a machine for winding spools of textile yarns, a number of winding stations are served in common by a motor driven driving shaft, at each station, the frictional driving cylinder is formed by two half shells clamped securely in position. Worn and/or damaged driving cylinders are replaced quickly and easily. The driving cylinder is secured against rotation and lateral motion, relative to the shaft, at each end by a nut in two halves, held together by two screws, and tightened on the stub of a conical sleeve inside the cylinder journal. The nut is formed in a single piece of a material such as cast iron or a thermosetting resin, which breaks cleanly under a shock load; a fracturing notch is provided on one or both surfaces extending across the full width, in addn. to two tappings and counterbores positioned symmetrically to the central axis of the nut. When made, the nut is clamped parallel with the fracturing notch aligned to a supporting edge, as in a vice, and broken by a sharp blow with a hammer. The fracturing notch is in the form of a bevelled indent extending on both sides of the bore of the nut, and may be located on both faces, so that the nut breaks easily. This makes it unnecessary to remove the driving shaft from the frame for the replacement of the spool driving cylinders, and prevents any damage to the screws, sleeves, etc. so that there is no need for adjustments, such as machining, rethreading, etc.
