Title: Mounting arrangement for supporting an inner conductor in a pipe
IPC: H01B9/06
Filed: 1974-08-20
Abstract: 1459604 Supporting a conductor in a pipe SIEMENS AG 20 Aug 1974 [18 Sept 1973] 36631/74 Heading H2C A supporting arrangement for a conductor 1 in a pipe 10 comprises a bearing 4 which is mounted in a control electrode 3 and lies around the conductor, and contact means (not shown) mounted on contact spring means 5 which engage the control electrode, such contact means being biased through apertures 41 in the bearing to provide electrical connection between the inner conductor and the control electrode. Preferable the arrangement is mounted in a pin type insulator 2. The bearing is a split ring formed from a flat band, Fig. 4, of P.T.F.E. enriched with carbon having obliquely cut-off ends and mounted in a shallow groove in the inside edge of the control electrode. The groove is of dimensions such that the bearing and not the control electrode contacts the inner conductor and a slot is left to allow for tolerances. The contact means are two brass balls, one each end of the contact spring means 5 which are of dimensions such that they just fit into grooves 32 and 33 respectively. Before the insertion of the conductor the balls are biased into the empty interior by the spring 5 so that on insertion of the conductor the balls are biased to give a good electrical contact with the conductor and the spring is pressed hard into groove 33 giving good electrical contact with the control electrode and hence between the conductor and the control electrode.

A sample of meat, after being subjected to a predetermined compression, has its volume and weight set up on potentiometers so that its density may be calculated, from which the fat content is determined. As shown Fig. 1, the meat sample in a bag 24 is supported on a beam 26 whose balance position, indicated on a dial 28, is restored to horizontal by operation of a knob 30 which incorporates a weight dial and is associated with a potentiometer 121 in a computing network, Fig. 2. The meat is then placed in a cylinder 40 and compressed by a ram 12 fed with compressed air at a pre-set pressure, indicated at meter 16. The ram is associated with a variable resistor 126 in the computing network, whereby the weight signal at the slides of potentiometer 121 is divided by the volume signal on rheostat 126 to give a density value which is fed to a voltmeter 54 (141) calibrated in per cent fat. A temperature compensating signal is obtained from a bridge network containing thermistors 148, 156 located on probes 38, which are inserted into the meat 24. The network includes selector switch 42 (130) for different types of meat. Details of the power supply for the electrical system are given.
