can someone tell me meaning of these?

'In case' without an of refers to a precaution for a [sometimes unstated] threat ('The forecast isn't good, so when you go out tomorrow you'd better take an umbrella in case [it rains]'). That is, the threatened thing might happen, and if it does you'll be prepared. It's sometimes used for an unspecified need: 'She took an extra £10.00, just in case' which, formally, means 'for contingencies'. In fact, that plural has influenced the jocular and informal 'for "just in cases"' (note: this is very informal, and possibly British English only - probably best avoided ).

With the of, the threatened thing does happen: 'In case of fire, break glass. - that is, it may not happen, but if it does there's something you should definitely do: 'In case of rain, open your umbrella.'

PS - In case you hadn't noticed, 'in case of' requires a noun (or a gerund - 'In case of your not having noticed...' )
