are two examples.
Sarah Crawford
Sarah Crawford makes brooches by combining
toothbrushes and toy parts with small prizes taken
from Christmas crackers. The resulting jewellery
is colourful and amusing. Don’t be deceived into
thinking this is an easy option. It would be very
easy for the brooches to look dreadful. But they
don’t. They are bright, cheerful and fun; not to be
taken too seriously and suitable for everyday wear.
Although the skills used to cut the brush to size and
assemble the parts are not complex in themselves,
Sarah always carried them out with care and
precision. The results speak for themselves.

Shops which sell stationery items have an interesting
display problem. Lots and lots of quite small items
– pens, pencils, rulers, rubbers, paper clips, paper
fasteners, drawing pins, tie-on labels, stick-on labels,
staples, string, adhesive tapes; the list is almost
endless. Yet they usually manage to show all these
items so that the customer can see what they want
and get it without disturbing all the other items. How
do they do it? Put the small items in a package
that can be hung on a hook and arrange the hooks
sensibly as shown in the picture on the right.

Q Question
Discuss with a partner the way that the following
items are displayed in shops:
• trainers;
• t-shirts;
• CDs;
• china ornaments;
• cosmetics.
For each item, describe how it is displayed and
explain why this particular method is used.
Sunglasses are often displayed in chemists shops
on rotating stands. The glasses fit neatly into slots
but are easy to remove and replace. There is usually
a mirror at the top of the stand so that customers
can see how they look wearing the sunglasses. A
four-sided stand takes up much less room than if the
glasses were displayed flat against a wall.

Soup beautiful soup 4
New Covent Garden Soup Company
The New Covent Garden Soup Company was set
up to manufacture soup that is as good as home-
made, prepared with only natural ingredients with no
preservatives, colourings or additives. The patented
production process is unique and took two years
to develop! The ideas for the first 30 types of soup
initially came from employees, and were primarily
vegetable. They were cooked as samples and
modified until the recipe pleased most people. Now
the company has extended its range to include meat
and fish. The ‘home-made’, all-year-round range is
complemented by summer and winter specials that
are based on seasonal vegetables. The company
also makes a soup-of-the-month, a clever idea to
introduce new and unusual flavours to the market.
The label is stuck on so the basic carton can be used for
any type of soup

the following ingredients for their white bean
with tomato and sage soup:
water, tomatoes, white beans, milk, cream,
onions, tomato puree, vegetable stock,
butter, brown sugar, sage, salt, garlic.
For each of these ingredients suggest a quality
assurance procedure that could be carried out
to ensure that it is suitable for use in bulk soup
production.
2 Scale makes a difference
To assure the quality of its produce the New Covent
Garden Soup Company monitors the quality of the
starting ingredients, the preparation, weighing and
preliminary cooking of those ingredients, the cooking
of the soup, and the filling, sealing and data stamping
of the cartons.
The soup is cooked in large sealed tanks. The
partially cooked ingredients are transferred to the
tanks and extra milk and cream are then pumped into
the tank through pipes. The total amount of these
ingredients and their rate of addition can be carefully
controlled. Steam is passed into the tank to heat
the ingredients, and air is pumped in to aerate and
agitate them. The pressure and temperature within
the tank are monitored and kept within strict limits as
is the weight of the mixture in the tank.
The exact details of the process are a carefully
guarded industrial secret, but clearly it requires a
sophisticated automated manufacturing system that
senses and controls weight, pressure, temperature
and time. The system uses computer control and
operators can check on progress and on the cooking
conditions by information presented on monitors.

There are two approaches to preventing people from
getting hurt. The first is the educational approach.
Through broadcasting and posters people, especially
children, are warned about the dangers. People who
work for the United Nations, charities and government
officials committed to de-mining, visit the areas
affected giving talks and providing information that
warn about the dangers and show people how to
avoid getting hurt. They also make arrangements
for the people to tell professional de-miners about
accidents that have happened. This gives the de-
miners some of the information they need for the
second approach – clearing the mines. This is of
course a very dangerous business. First the mines
have to be found and then they have to be made
safe or destroyed. Of course, it is no good finding just
some of the mines in an area. All the mines have to
be detected and removed for an area to be safe. This
involves very detailed searching by careful digging
and using mine detectors. Mines are often hidden
in vegetation and many of them are quite small so
vegetation has to be cleared away before searching
can begin. This is very dangerous and so this is
where the Shadow Robot Project comes in.

Things to consider
An interior designer’s job is to enable us to live and work
in places that are comfortable, attractive and functional.
The designer of this office had to think about:
• what people use the room and what they need to
do;
• the shape and size of the room;
• the availability of gas, electricity and water;
• the positions of doors and windows;
• the furniture and how to arrange it; Office design should ensure that everyone can do their job

Tackling the task
Using plans
Interior designers use plans to help them make design
decisions. A basic plan shows the position of the walls,
doors, windows and electricity, gas and water points.
The plan can also show which way the room is facing
and how much natural light it will receive.
Card cut-outs will help the designer try out different
arrangements of furniture and equipment and think
about the advantages and disadvantages of each
layout. The layouts will also show how people and
materials might move around or through the room.
Using drawings
To help decide on the colour scheme and furnishings the
interior designer draws a perspective view of the room
and tries out different colours and decoration schemes.
She can add samples of fabric and wallpaper.
