摘要： The invention relates to a process for joining a hollow profiled section (1) to a component (2) of a vehicle which bears flat against it by means of soldering, with a solder (4) being introduced between the hollow profiled section (1) and the component (2) and then being liquefied by the introduction of energy and, as it solidifies, producing a fixed join between the hollow profiled section (1) and the component (2). To achieve a durable soldered join between the hollow profiled section (1) and a component (2) of any desired configuration which bears flat against it in a simple way, it is proposed that a hollow (3) is formed on the component (2), in that the solder (4) is deposited in the hollow (3), in that the component (2) is then positioned relative to the hollow profiled section (1) with the hollow opening (6) facing the hollow profiled section (1), and in that then, in the contact position, the component (2) is acted on by resistive electricity in the hollow region, with a compressive force being exerted on the hollow outer side (8) by means of a resistance-welding electrode.

摘要： A program control device for the photographic cycle is present, which contains an electronic read-only memory for each photographic program. A resettable pulse counter is actuated step-by-step by a clock pulse generator and controls the selected memory to deliver program signals predetermined by its program. The outputs of all read-only memories are connected to the component parts they control via a program selector circuit. A correction memory is controllable for the input of correction program elements and is connected in parallel to the read-only memories. A recognition memory controlled by the pulse counter is connected to the program selection circuit and the program steps to be corrected are storable therein, so that, upon reaching such a program step, the correction memory (60) supplies the program in place of the respectively selected read-only memory.
