		| Abstract: | 
		An accretion disc in an intermediate polar is necessary to produce the dominant spin period effects and enables the `accretion curtain' model to explain the spin period variations from the optical to the X-ray. There is growing evidence that part of the accretion stream overflows the disc, which may result in orbital and beat period X-ray modulations. |
