Abstract: The pieces to be palletized are conveyed by a roller table to bar elements which reciprocally turn the pieces so that they face each other. Grippers then grip the facing pieces which originally lie flat, so as to move them into a vertical parallel position on a conveyor belt. An upper conveyor belt engages the top of the vertical parallel pieces to hold them in correct orientation. An automatic strapping mechanism them applies this strap around the pieces. A roller table is provided for lateral movement of the strapped packages. The roller table which initially receives the pieces pass in a horizontal flat position on the roller table. A section of the roller table has portions of its rollers removed so that undersized pieces fall through the opening thus formed. Only pieces with correct size, that is, unbroken pieces, are conveyed along the parallel passages of the roller table.

Abstract: Methods of forming joints between bars of materials such as mild steel are disclosed. In one method, the bars are arranged to lie in generally parallel planes but with their axes at an angle to one another, and a plastically-deformable tubular stub of round or square cross-section is disposed between the bars with its axis substantially intersecting the axes of the bars, which are then pressed together to deform the stub partially around the two bars. In a second method, a bar is arranged in a T-formation with a hollow member, two opposed regions at the end of the tubular member are deformed inwardly and back along the member axis, and the bar is then pressed into the groove so-formed at the end of the member, to deform the end portion partially around the bar. Heat may be used, in the former case on the stub and in the latter case on the tubular member, so that after completion of the joint the heated stub or tubular member will cool and contract, firmly to grip the or each bar.

Abstract: A control device for use with a respirator which has a breathing gas supply and a separate pressure gas supply comprises a gas control device housing with a connection for the patient and a bottle pressure line and a medium pressure line connected to the device and controlled by valve elements. A lung machine for respirators must guarantee, even upon failure of the important pressure reducer in the respiratory gas feed line, that the apparatus user is supplied with respiratory gas. This is done here in a simple manner by bypassing a swivel valve controlled by means of a breathing diaphragm. A piston valve, connected via a control line with the medium pressure P.sub.MD and, directly with the high pressure P.sub.HD, opens upon failure of the medium pressure and through the high pressure always present, directly a high pressure valve contained in the piston valve.
