Title: Apparatus for and Method of Testing the Number of Turns on a Coil
IPC: G01R31/72
Filed: 1979-03-22
Abstract: The apparatus includes a rod 1 energised by energising coils 2, 3 separate from the rod arranged at predetermined axial spacings S from the ends of the rod, each coil being of similar field generating characteristics. A stand 10 supports the energising coils and enables the rod to be removed therefrom to permit placing of a coil to be tested on a support 6 in a zone Z of uniform air flux between the energising coils. Prior art difficulties in establishing the zone of uniform air flux are readily overcome by suitable separation of the energising coils. The permeability of the rod is not changed by mechanical stress resultant from contact with the test coils since it is removed during placement of these coils. Voltage supply means for energising the coils are disclosed in combination with the apparatus. A circuit for obtaining a visual indication of the number of turns on the tested coil includes a digital panel meter calibrated using a coil of known turns. Linearity is improved by windings on the rod at regions of maxima and minima induced flux. The circuit compensates for fluctuations in supply voltage. <IMAGE>

Title: Data transmission system
IPC: B60R16/02
Filed: 1979-05-01
Abstract: This relates to a data transmission system, especially for remote control application in difficult environmental conditions, in which the transmission medium is a closed loop arrangement which interconnects the master station and the substations of the system.

The substations are capacitively coupled to the loop conductors, the values of the capacitors being so chosen that the couplings are low impedance at the carrier frequencies and high impedance for the usual mains frequencies. As described, a screened cable comprising three pairs is used, one pair P for power, one CP for clock, and one DP for data signals. <IMAGE>

Title: Electrolytically etching aluminium
Inventor: DYER CHRISTOPHER K
IPC: C25F3/04
Filed: 1981-06-18
Abstract: A method of etching aluminium by applying an alternating electric current to aluminium which is in contact with an electrolyte containing hydrochloric acid, in which the alternating current has a symmetrical waveform wherein the current rises rapidly from zero to a maximum, then subsequently decreases rapidly in a first stage (t1) to an intermediate value which is about one-third to about one- half of the maximum, and thereafter decreases more slowly to zero in a second stage (t2). Thereafter the current rises and falls in the opposite direction with the same waveform. The ratio of time of the second stage to time of the first stage of the waveform is in the range from 1 to 6. By this procedure higher capacitance values of the etched aluminium are obtained in comparison to prior procedures. <IMAGE>

Title: Centrifugal moulding concrete pipe
Inventor: ASKIN MICHAEL
IPC: B28B21/34
Filed: 1981-06-22
Abstract: A machine for spinning a centrifugal concrete pipe casting comprises mould 10 and a base formed by a main frame 1 and a sub-frame 2 which is mounted so that it can perform oscillatory vibrations about a connection 3 to the main frame 1. These vibrations are induced by twin geared linear variable speed vibrators 15 and the vibrations are ted transmitted through idle wheels 8 to the mould 10. The mould 10 is rotated by driving wheels 6, which are in turn rotated by an electric driving motor 12. The driving wheels 6 and the motor 12 are mounted on the main frame 1, which is not vibrated. This vibrating arrangement enables the mould 10 to be very effectively vibrated and this in turn brings about rapid compaction and de-watering of concrete being cast in the mould 10. <IMAGE>
