Abstract: Arrangement for ensuring in connection with the production of concrete screed beams for concrete floors or similar devices good linerarity of the product when casting in accordance with the so-called battery method. On a bed of beams (1) pipes (2) with a certain degree of levelling (3) are placed. In the mould the beams (1) become the underside whereas two nearby pipes (2) become the side walls. The arrangement consists in a plate (5) between two beams (1). The plate is located and shaped in such a way that the T-shaped rail (4) at the bottom of the pipe fits into a recess (6) in the plate. In this way the pipes are aligned, which is the necessary condition for ensuring good linearity of the product.

Abstract: During spot welding with long welding jaws 14 of inner support walls for fire protection doors 3 of parallelepiped shell structure, the problem of coating of the welding jaws 14 occurs. During each welding pass, a coating layer is produced at the places of a welding jaw where spot welding occurs, which means that after a certain number of welding passes the coatings become so sizeable that the welding jaw 14 is unusable. The purpose of the invention is to increase the lifetime of a welding jaw 14. This is done in that the door 3 and the welding jaw 14 are made to be moveable in relation to each other so that the layer coating is spread along a larger portion of a welding jaw 14. <IMAGE>

Abstract: An output stage with automatic level control for power line signalling, including a controlled amplifier (F1) and a feedback circuit for sensing the output voltage (V O+v O) of the output stage and for supplying a control signal (v<4>) to a control input of the controlled amplifier (F1). The feedback circuit includes a comparator (K) for comparing an alternating voltage (v1) which is responsive to the alternating voltage component (v O) at the output of the output stage and which is furthermore superposed on a first direct voltage (V1) with a second direct voltage (V2). As control signal to the controlled amplifier (F1) there is utilised the voltage (v4) across the capacitor (C4), the voltage of which increases or decreases in response to the comparison result of the comparator (K). The amplitude of the alternating voltage component at the output of the output stage can thus be kept to a substantially constant value determined by the first and second direct voltages (V1 and V2).

Abstract: The invention relates to a device (2) which supplies breathing gas mixed with an additive gas to a patient for pulmonary diagnosis or pulmonary treatment. The device (2) comprises a gas mixing unit (4) through which a relatively large flow of breathing gas is achieved from a first gas source (6) through a first pressure regulator (8) and a second pressure regulator (10). The breathing gas passes through a connecting tube (24) from which the patient can breathe spontaneously through an inspiration tube (26), thereby inhaling air from the connecting tube (24). Expired gas passes via an expiration tube (36) to the connecting tube (24). Additive gas is supplied from a separate gas source (16) via a second pressure regulator (18) and a second flow regulator (20). The additive gas is supplied in a flow which is considerably smaller than the flow of breathing gas, whereby a very small but accurate concentration of the additive gas can be achieved in the breathing gas. The large flow prevents a reactive additive gas from reacting before being supplied to the patient. <IMAGE>
