Here is one link who gives details about all the cap information. and Cap is implemented on monthly bases.
How will the Temporary Immigration Cap work?
The UK Border Agency will operate the system on a first come first served basis with a limit placed on the number of Tier 1 General Visa applications considered in any one month. If an application is submitted after the limit for a month is reached, the application will be held and considered in the following months limit. Applications will continue to be accepted during the period in which the limit has been reached; however the UKBA will not process the application until the next month. Applications will be held in a queue by order of the date on which they were received. Applications in the queue will be processed when the following month's limit is opened. If application numbers look as though they will exceed the total limit for the whole of the interim period, the UKBA will notify the individual at the time of application. Details of waiting time will be announced on the UK Border Agency Website.
As the Temporary Immigration Cap for Tier 1 General is believed to have been set at 5,400 for the remaining 8 and a half months of the financial year the monthly limits are believed to be:
318 Tier 1 General applications in July 2010
635 Tier 1 General applications in August 2010

635 Tier 1 General applications in October 2010
