Title: Improvements in or relating to radio direction bearing indicators and the like
IPC: G01S1/02
Filed: 1927-08-26
Abstract: 301,116. Whistlecroft. A. W. Aug. 26, 1927. Index hands and pointers.- In order to facilitate the comparison of a wireless directional signal against the compass bearings, particularly where only one operator is available, such as the pilot of an aeroplane, an auxiliary pointer 4 is clutchmounted on the shaft 2 of the moving-coil system so that it can rotate freely when pressed downwards against a spring 9. In operation the ordinary indicator 1 is moved to and fro over a scale in order to ascertain the minimum position as usual, but the extent of the swing is determined by the traverse of the auxiliary pointer 4 between the shoulders 5<a>, 5<b> of a limit stop 5. The swing readings are thus localized by "feel," whilst the pilot reads the compass bearings directly.

IPC: G11B15/58
Filed: 1967-05-16
Abstract: 1,195,121. Automatic tension control systems. INTERNATIONAL COMPUTERS Ltd. May 7, 1968 [May 16, 1967], No.22616/67. Heading G3R. In an automatic tension control system for tape handling apparatus of the type wherein the reel driving motor 8 is controlled according to the position of the tape 3 in an evacuated reservoir 10, a signal indicative of the tape position is obtained by using at least one thermistor subjected to an air-flow which is varied by movement of the tape in the reservoir. The described embodiment uses a reservoir having two compartments 20, 21 respectively associated with thermistors 19, 28 through apertures 15, 25, the arrangement being such that the normal position of the tape is at gap 22 midway between the two compartments. Whilst a signal dependent on the resistance of the thermistor could be used to control the motor, each thermistor is made part of a bridge network such as 19, 34, 35, 36 shown in Fig. 2, which network is balanced by the thermistor resistance when the heating effect of the bridge voltage and the cooling effect of the air-flow compensate one another. Change in thermistor resistance due to tape movement is immediately counteracted by a change in the bridge voltage to restore the thermistor resistance, this voltage giving a measure of the tape position and being used to control the motor 8. The output of the bridge containing thermistor 19 is obtained from a terminal 51 and that of the bridge containing thermistor 28 from a terminal 59 via terminal 53 and an inverter 60, the two outputs being algebraically added to control the tape at its normal position 22. The functioning of the circuit of Fig. 2 is described for initial energization and normal operating conditions. The size and spacings of the apertures 15, 25 may be varied and the control system may operate with only one reservoir compartment and thermistor giving a signal dependent upon changes in resistance.

A composite metallic blank of a rotor for an electrical machine is made by putting a magnetically non-permeable (first) metal (15) to be melted, into a mould 10 containing magnetically permeable metal parts 13 of the rotor or into a container formed of that metal and including those parts (13) within it, then heating the mould or container in a reducing atmosphere (and maintaining a temperature exceeding the melting temperature of the first metal so that a surface diffusion occurs between the metals) before cooling to solidify the molten (first) metal. The rotor blank is removed from the mould 10 but when the container is used it becomes part of the blank. The container or mould 10 is supported on a base 9 within an induction heater 2 mounted on a post 1 which incorporates a supply for the heater. In the spaces (14) between steel rotor parts (13) are put a Cu-Ni-Mn based alloy (15) (magnetically non-permeable) and a flux (16). The heater 2 is then activated to melt the flux and then the alloy (15); the mould is oscillated by a vibrator 8 to aid degassing and separation of impurities while the metal surfaces diffuse. The vibrator is switched off, a cooling sprayer 5 is raised by a drive 11 into the mould 10 or container and the heating is reduced, so that there is directional solidification of the alloy. The rotor blank thus obtained is heated in oil to temper and anneal the steel parts (13) and aged by heating in air for dispersion-hardening of the alloy parts (15).
