LONDON -- The FTSE 100 (INDEX: ^FTSE) is doing nothing today -- up a few points, down a few points. At the time of writing it stands at 5,770 points, four points down on the day, with the big banks losing a percent or two.

But whatever the index of top U.K. shares is doing, there were quite a few results out today. Here are three companies from the FTSE indexes whose figures led to nice price rises.

Costain Group
(LSE: COST.L) gained 51.5 pence (6.8%) to 814 pence on the day it released interims, showing a 52% increase in pre-tax profit to 15.4 million pounds, and a 78% rise in earnings per share to 21.2 pence. The interim dividend was lifted by 7.6% to 3.5 pence per share.

The chairman of the engineering services group, David Allvey, said, "This is another strong performance with an increase in profit, robust cash balance and a high quality order book comprising both new contract awards and contract extensions," and told us the firm is on target to meet full-year expectations. With forecasts suggesting a dividend yield of 4.8%, rising to 5.1% next year, it could be one to watch.

(LSE: DLC.L) enjoyed a 51.5 pence (6.8%) rise to 814 pence after telling us of record-breaking first-half results. The software developer saw revenues rise 15% to 22.9 million pounds, with pre-tax profit up 67% to 2.09 million pounds. Basic EPS of 26.2 pence (up 77%) led to a 43% lift of the interim dividend, to 2.5 pence per share.

Delcam shares have soared by around 90% over the past 12 months, and have four-bagged since the start of 2010. Forecasts value the shares quite highly, with a price-to-earnings ratio of 16 for this year, falling to 14.6 next year, and the dividend is only going to be around 1% -- but that's often the case with growth companies.

Falkland Oil & Gas
(LSE: FOGL.L) perked up on nice interims, gaining 3.2 pence (3.6%) to 91 pence, after a very busy first half. Highlights for the period included the successful raising of $75 million (48.5 million pounds) through an equity placing in January to fund the firm's drilling plans, and farm-outs to Edison International confirmed in June, and Noble Energy announced on Aug. 6.

The company also took control of the Leiv Eiriksson rig in July, and its Loligo well spudded on Aug. 3. There are high hopes for Loligo, and with $220.7 million cash on the books, the future is looking pretty promising.
