Abstract: The invention relates to a method for making tubes formed with holes in their peripheral wall, particularly muffler tubes, in which the tubes are formed of sheet metal and subsequently welded along abutting edges of the sheet metal. Known from practical application is a method of the type defined above, in which a hole pattern is initially punched into a sheet metal strip. The metal strip is subsequently formed, as by a roll forming method, into tubes which are then closed by a longitudinal weld seam. After the welding step the tubes are cut to length by means of a cutting device, the operation of which is controlled depending on the hole pattern. It is the object of an invention to provide a method and apparatus of the type defined above which in addition to the advantage of economical production offers the possibility of forming the tubes with holes over their entire periphery. With regard to the method according to the invention, this object is attained by introducing a backing element into the previously welded tube and forcing it into engagement with the interior wall surface thereof, followed by the formation of holes from the exterior in the area of the tube supported by the backing element.

Abstract: A contactless motion detector is energized from a source of current via a pair of supply leads and delivers an output signal by way of a further lead through an Exclusive-OR gate to a control electrode of a binary electronic switch in circuit with the source and a load to modify the flow of load current upon the approach of a metallic element, for example. The Exclusive-OR gate, having one input connected to that further lead, has another input connected to an ancillary lead which in turn is connected to the other supply lead through a decoupling diode. A selector switch enables completion of the load circuit directly via the latter supply lead, thereby causing inverted transmission of the output signal of the detector to the control electrode, or by way of the ancillary lead to prevent the inversion of that output signal, whereby the load current can be either increased or reduced upon the occurrence of the event to be detected.

Abstract: A frequency synthesiser produces a variable frequency output using a controllable oscillator and a variable frequency divider which form part of a phase locked loop. The integer division ratio of the divider can be altered during a division cycleto simulate a fractional divisor value. The phase noise or jitter which is caused by the step change in divisor value is removed by altering the divisor value in accordance with the terms of a plurality of sequences, each of which sums to zero and which represents successive rows in a Pascal's triangle. A cascaded sequence of accumulators is used to determine the starting instants of each sequence, and the length of each sequence is dependent on the number of delay lines used. Although only four accumulators are illustrated, more can be added to give any desired degree of phase noise cancellation.
