The following is supposedly a true story. To be included, besides being true, the story is most likely strange, weird, surprising, or funny.
New York, NY
Police across the nation are warning people who wear pagers to be on the lookout for the latest scam.
According to police, pagers in several states have been beeped by a number displaying a 212 area code (New York) and the prefix 540. When the victims return the call, they are charged $55 on their phone bill.
The call the respondent makes has been electronically linked into a 900 “pay-per-call” system which allows the charge to be added to the phone bill.
“People will look at the number and say ‘Gee, who is calling me from out of state? It must be important,’” said an investigator.

Dogs lie around all day sprawled on the most comfortable piece of furniture in the house.
They can hear a package of food opening half a block away, but don’t hear you when you’re in the same room.
They can look dumb and lovable all at the same time.
They growl when they are not happy.
When you want to play they want to play.
When you want to be alone they want to play.
They are great at begging.
They will love you forever if you rub their tummies.
They leave their toys everywhere.
They do disgusting things with their mouths and then try to give you a kiss.
Conclusion: They’re tiny men in little fur coats.

HP Series Hydraulic Cone Crusher is a kind of advanced hydraulic crusher with high power, reduction ratio and productivity recently researched and
manufactured by Henan Liming Heavy Industry company. It is a world-level cone crusher developed from the up-to-the-minute technology of Germany.
On the basis of absorbing advanced technologies of various cone crushers from several countries, the equipment has the major advantages of known
cone crushers up to now. This new type of cone crusher not only improves the production capacity and crushing efficiency, but also widen the
applying area, the hardness of materials range from limestone to basalt. It has a second-to-none crushing performance in the work of medium-size
crushing, fine crushing and super fine crushing.
Cone crusher is widely used in such industries as metallurgy, building material, road construction, chemical industry and silicic acid. It is
applicable for fine and micron crushing for various medium and above hard rock, ore, slag and refractory materials. The Hydraulic Cone Crusher
is the improved type of spring cone crusher and can be used to replace ordinary hydraulic cone crusher in the line of mining and construction.
It is the most ideal equipment for large stone crushing factory and mining industry.

The potential cost savings from using a mobile crushing and conveying system based at the rock face are significant: a study conducted by Tampere
University in Finland found a 31-percent cost savings over semi-mobile installations in similar applications. The savings over using haulers is
greater, as the excavators or wheel loaders used for feeding the haulers can be downsized (to ones more suited to the crusher rather than the
hauler); labor costs are reduced too as there are no longer hauler operators to employ. In terms of manpower, the excavator or wheel loader
operator can control the complete crushing operation. Fuel usage is also drastically reduced and there is also no longer a need to build
elaborate and well-maintained haul roads — a significant additional and ongoing expense.
With a similar lifespan to that of stationary systems mobile plants have few disadvantages. There are even significant environmental advantages
of using a mobile system: eliminating haulers reduces noise, vibrations and emissions — and fuel. Safety too is enhanced, as fast moving
vehicles play a significant role in site accident statistics.

Mobile systems will not totally replace the stationary variety. In quarries where supply is large (more than 500,000 tons per annum) and constant
in a small radius the stationary plant is justified. But where supply is not large then mobile plants have the advantage of being able to
circulate between locations and build up stockpiles. In mining, the advantages of having a primary crusher feeding a conveyor system are
becoming more recognized as an effective solution. Once this is fully established the industry will move to a mobile second stage and finally
third stage of crushing. The United Kingdom is already at this third stage, whereas the United States has been catching up fast from a late
start.
With their lower capital and operating costs, flexibility of siting and elimination of the need for haulers and haul roads, mobile crushing
plants offer an attractive alternative to the traditional stationary crusher and hauler system. The reduction in manpower, fuel usage and
pollution is mirrored by an increase in health and safety.
Offering higher productivity and low cost per ton production, truly mobile tracked crushing plants are destined to become a more common sight
in quarries and mines worldwide.
