Abstract: An improved method of ultrasonically welding together two conductors having differing lateral dimensions comprising selecting a welding capture fixture having lateral sides spaced apart by a distance substantially equal to the lateral dimension of a first conductor having the greatest lateral dimension. The first conductor is placed in the selected fixture so that the first conductor is proximate to or substantially engages both lateral sides of the fixture. The second conductor is formed so that at least a first portion extends laterally beyond a second portion. The second conductor is placed into the select fixture so that the first portion is proximate to or substantially engages one of the lateral sides of the fixture and the second portion is proximate to or substantially engages the other lateral side of the fixture with both portions substantially engaging the first conductor.

Abstract: A gas thermometer has a case with a case end section (10) made of metal of good thermal conductivity and a main case section (14) made of material of poor thermal conductivity. By means of separating walls (46, 48, 62, 64, 70) and reflector walls (66, 68), two sound paths are created in the interior of the thermometer case, which differ by twice the distance between the reflector walls (66, 68). The phase difference of partial sound wave fields which are obtained by splitting a sound wave field produced by a common sound generator (40) between the two paths is converted to an electrical signal corresponding to the temperature in the case end section (10) by using microphones (26, 28) and an analyzing circuit (92) connected with them.

Abstract: A temperature sensor construction suitable for use in mechanically oscillating systems features a protective tube 8 containing a temperature sensor 11, a springy carrier board 1 with conductive tracks 2,3 and terminals 4,5,6,7 for a signal transmission conductor. The carrier 1 is mounted, under spring tension, facing the inner surface of the protective tube 8. The conductive tracks preferably run parallel to the axis of the protective tube and have contacts 4,5 at one end for connection to the temperature sensor 11 and contacts 6,6',7,7' at the other end for connection to the signal transmission leads 12, 12', 13, 13'.
