Using OR in a claim

The "or" can be used in a claim, when an integral function of an invention, such as:

an dial enabling said appliance to access cold, warm or hot water

but not in situation where there is a choice of machines, i. e., a different machine, such as

machine running on diesel or gas

it is all obvious, common sense.

The idea of going green in spare sparts:

Trying to dispose of an old spare tyre, I realized it would be a pity to throw it just anywhere - the rubbish truck does not pick it up, the city recycling center does not take them, the little river running through the neighborhood has been cleaned up of these things serving as shore guards. Then I realized - I have more car parts that are a pity to throw into the nature. The do-it yourself repairs I used to do generated one too many of these non-biodegradable, annoying car parts. The easiest solution is ordering used car parts online, I searched in the "Automotive Shopping Online" category, and chose the 247spares, one of the top 6 hits. Their used car parts prices are very low, the orders processed and arrived on time. Judging from feedback, the standard delivery time is within 24 hours. I have been building a smart car from a kit, and the 247spares has a special telephone support line for smart car owners, just for finding the right car part. They have got glow plug sensors for my high tech diesel motor. The 247spares also saves me from having to spend a good chunk of time in uncertainty at Smart car breaker yards. Instead, a completed form on the 247spares site, with information about one's Smart Car vehicle and the car spares required, and the part is easily found at the best prices. All their Smart Car breakers offer fully guaranteed used Smart Car car parts, with Next Day Nationwide delivery services across the UK.

Checking houses for ghosts is also a valid business opportunity

http://www.isurhousehaunted.com - is the strangest online business I've stumbled upon in a long, long while. The site help people find out if their house could be haunted. Do objects go missing or disappear in your house? Do you hear strange noises at night? Have you lived in your house for over 5 years? Answer easy questions about yourself and your own superstitions. Do you believe in black cats, walking under ladders, etc.? A rather clever idea to make money online, don't you think? I believe this particular site accepts US traffic only.
