A carbon lined bearing is made from a solid carbon blank a having an outer diameter corresponding to the outside diameter of the bearing liner and a metal bearing body c having a closed bore having a diameter slightly greater than the outside diameter of the blank. A heat curable adhesive f is placed on the bottom of the bore, the quantity of adhesive being greater than that required to make up the difference in the diameters of the blank and bore. The blank is placed on top of the adhesive and an endwise load applied to urge the blank towards the bottom of the bore. The metal body is heated to the curing temperature of the adhesive while the load is applied so as to cause the adhesive to form a continuous layer between the blank and the walls and bottom of the bore, and to cure the adhesive. After cooling, the composite body is machined to provide an axial bearing bore i and to remove material projecting beyond the desired end surfaces of the bearing. The carbon blank may contain additives such as antimony or copper.

[Also in Division G4]  A tristable circuit used as a frequency divider comprises three transistors 1, 2, 3 coupled via voltage dividers e.g. resistors 10, 13, and also having diodes 7, 8, 9 connected between them. If at one instant transistor 2 is biased on, the voltage at the base of transistor 3 is below cutoff voltage because of the values of resistors 11, 14. The bias at the base of transistor 1 is below cut-off due to diode 9 being forward-biased and reducing the voltage at the voltage divider junction. A pulse input at 31 passes via a differentiating circuit of capacitor 29 and resistor 28 to the three input diodes 25, 26, 27. Only diode 26, in this case, will be forward biased so turning transistor 3 on and biasing 1 and 2 off. An output at 32 will be at one third frequency of the input frequency at 31. The transistors used in Fig. 5 are silicon but in Figs. 3, 4, 7, germanium transistors are used, and, having a much lower cut-off voltage, require a diode in series with their bases in order to fulfil the circuit biasing conditions.
