Paper A Electricity/Mechanics 2016 - our main claim
Here it is. Our attempt at the main independent claim of A E/M 2016.
Claim 1. A siphon comprising a housing; the housing comprising:
· a reservoir,
· an inlet opening, and
· an outlet opening;
· the housing being arranged such that liquid can flow from the inlet opening to the outlet opening via the reservoir and fill the reservoir up to an overflow level of the reservoir;
characterised in that the housing further comprises a wall exposed on an inner side to gas entering the housing from the inlet opening and exposed on an outer side to gas entering the housing from the outlet opening; and
the wall extending at least to the overflow level to prevent gas from flowing from the outlet opening to the inlet opening.
The main problem in this exam seems to lie in covering 4 embodiments which fall into two groups (Figs.2 and 3 versus Figs.4 and 5). This makes it difficult to define the position of the openings and puts the pressure on a correct definition of the wall. This is particularly relevant since also in the traditional siphon of Fig.1 the wall of the tube plays a role in preventing gas entering.
We may post some dependent claims at a later moment.
Looking forward to your comments,
All blog threads allow anyone to add comments and already have a lot of valuable, interesting and sometimes surprising discussions between many candidates who posted their comments as well as tutors resulted from those.Any remarks, (different) opinions and questions as are welcome! Please post your contribution as comments to this blog, so everybody can paticipate in and benefit from the discussion/ explanation.
Please do not post your comments anonymously - it is allowed, but it makes responding more difficult and rather clumsy ("Dear Mr/Mrs/Ms Anonymous of 02-03-2016 14:56"), whereas using your real name or even a pseudonym (nick-name) is more personal, more interesting and makes a more attractive conversation.
