Acquiring another company

[MarillionFan]

Completely theoretical question.

Let's say you've accumulated X in your LTD company A and wished to purchase another business operating as company B.

Also let's assume that company A and company B are different businesses. So company A your LTD decides to buy say company B (an recruitment company, plant hire company, wholesale business) say.

What would the process be, and how would the merging of the entities work(if at all)?

I'd assume that company A buys the shares of company B. Owner of A then has control of B, makes the business decisions and has Directorial responsibilities for B.
Profits from B can be distributed as dividends to the shareholders, in this case company A so those dividends become an income stream for A.

Seems fairly simple to me.
