In resistance welding a metal part to the rear surface of a metal sheet having dielectric material on its front surface, two electrodes connected to a transformer and having individual pressing means are employed, one in contact with the part which has only a small surface in contact with the rear surface and the other in contact with the rear surface close to the part, the front surface is supported on a resilient support and the welding current is passed for not more than 1/50th second. The parts may be feet, eyelets, nuts, bolts, studs, screw-threaded rods, &c. and the sheet may form part of metal furniture, door panels, vehicle coachwork, valises, containers, &c. The part to be welded may be provided with at least one projection, to allow projection welding to be effected, having a diameter not greater than 2-3 mm. and the welding pressure should not be greater than 40 kg. The electrodes may be mounted side by side on the head of a welding machine, each having an independent spring-pressing means, and the lower part of the machine may provide a rigid support covered with material the same as that, e.g. polyvinyl chloride, on the sheet.

[Also in Group XIII] In a combined washing and spin-drying machine, a movable system comprising a basket 1, Fig. 1, a non-rotatable imperforate casing 3, drive-shaft 16, a sleeve 46 thereabout and a driving and transmission structure 17 are movably supported on a carrier assembly 38 which is mounted for movement on a horizontal support surface 29 formed by an annular portion of a rigid member 28 secured to the machine walls. The carrier assembly has an annular section 39, the lower face 40 of which is adapted to engage ball-bearings 32 mounted in a race on the support surface 29, the movement of the bearings being limited by springs 36 so as to permit horizontal movement of the carrier assembly. The annular section 39 also has arms 42 providing spherical seating surfaces 43 for the support of a hemi-spherical member 44 rigidly secured to the casing 3 and to a sleeve member 46 so that the movable system is tiltably supported by the engagement of the member 44 with the arms 42. The mass of the movable system is distributed so that its centre of gravity is sufficiently low that upon tilting of the system the centre of gravity always moves up on movement of the shaft 16 from the vertical axis. The movable system is horizontally centred by springs 49 secured by lugs to the sleeve 46 and member 28, and a vibration damping means 52 is provided which comprises a horizontal member 54 with a surface of damping material, which is mounted on a spring arm 53 secured to the annular section 39, which surface engages a surface of a member 56 of the rigid member 28. In a modification the ball-bearing arrangement of Fig. 1 is replaced by a carrier assembly 132, Fig. 2, having a continuous lower annular surface 133 of a damping material which is in slidable contact with a horizontal support surface 129, which may also be of damping material. The basket 101 is housed in an imperforate tub 114a which comprises the side walls 106 of the drier cabinet 104 and a horizontal member 113 continuously secured to the walls 106, a portion of which member forms the support surface 129. The surface 129 forms a liquid seal in the tub by contact with the surface 133, and the surfaces 134, 137 of the hemispherical member and carrier assembly, respectively, also form a liquid seal.
