FILLD OF TI-~E IN~IE~~IOI~
xhe present invention relates to the field of ice making equipment arid more particularly, to an ice resurfaces fox forming a layer of ice on a cool surface, such as may be found in hockey and ice skating arenas.
. - iD BACICGROLrLVD QF'I'FiE 1NVENTTON
Arenas used fox hockey and ice skating are typically formed on concrete floors in which are embedded pipes carrying a chilled solution. The chilled solution lowers the temperature of the concrete floor to as low as 10°x, well below the 32'F freezing temperature of water. The chilled Floor is then ~taaded with water which freezes to foam an ice surface. Typically indoor ire skating rinks have a layer of ice of about 1 %x inches in total. The ice is built up to this thickness by repeatedly flooding the surface with layers of water. The layers freeze ane onto the next to foam the full layer of iee. Tn a typical application, after the first couple layers of ice are placed on 2o the chilled surface, the ice is painted white to prorride a good contrast to the ice surface. A couple more layers of ice are placed over the paix<ted layer for protecting the painted ice layer. At this point, additional graphics are painted on the ice such as, for example, the red and blue lines, goal lines and the like for hockey as well as any additional advertising graphics, such as corporate logos. A couple more layers of ice are then placed on top of these ice surfaces to provide for the final Layer of ice far hockey or ice skating.
In order to provide for the optimum surface for hockey attd ice skating, it is desirable that the ice be relatively dense. This is generally accomplished through the use of ktot water as it freezes to a more dense and harder ice surface then cooler water.
Generally, the water is heated to about 150°F for the making of ice xn an arena.
During maintenance of the ice, after the initial ice is Formed, an ice resurfaces such as a ZamboniTM or alympiaTM is used to shave the ice to remove slush, snow and dirt front the surface of the ice. The resurfaces then floods the surface of the ice with fresh water. This is generally accomplished by dragging a rag or cloth at the rear of the ice resurfaces onto which water is spread to provide ~or a uniform film of water to be distributed over the ice surface. The snow and shavings picked xxp by the ... ., rJ-12 773CA , . .
resurfaces are stored in a snow tank which are then dumped after the resur~facer is , finished. , . ."
. 'T~pically, to resurface a sheet of arena ice, about 12~ gallons of water is heated to ' 150'F. This requires a significant amount of energy to both hr at the water as well as czeate a refrigeration load in the cooling solution of the chilled floor to properly freeze the surface of the ice. , There have been attempts in the past to provide for reduced energy consumption io during ice making and maintenance. por exannple, US Patent 5,536,411 describes a process whereby the water used to flood the ice rink is de-mineralized by reverse , osmosis and carbon filtered. In this way it is only necessary to heat the wakes to ' about 90°F. However, this skill requires some additional energy to be used far the ' processing of the water. , ' 1~
US Patent 4,953,360 describes the use of an additive in the water used to form the ice or ice layers, The additive comprises a surfactant, a primary alcohol arid a silicone.
The surfactant acts to reduce the surface tension of the water while the silicone acts as a defoamer collapsing any bubbles formed on the surface and also as a.Iubricant 2o when pressure is applied on the ice such as an ice skate blade. The alcohol is believed to aid in providing a generally homogenous mixture when added to the water. Through the use of the additive this allows the water to be only heated to about 45 - 55'F. However, the savings in energy are offset soruewhat by the cost of ;
the additives.

DETAILED DESCRIPTION ~F THE INVENTION
An ice resurfacing machine 10 according to the present invention is illustrated in Figure 1. The ice resurfaces 10 includes a tank assembly 12, wheels 14, an operatax position I6 and an ice resurfacing unit 18.
. ~ The ice resurfacing unit includes a scraper bar 20 to shave the ice surface and prepare fvr receiving the water from the resurfacing. The shavings from the scraper bar 20 are fed by means of a conveyor unit 2z to the snow holding tank 24 contained within , the top portion of the tank assembly 12. 'T'he bottom parkion of the tank assembly 12 holds a water tank 26 which contains the water for application to the surface of the ice. A delivery pipe 2$ distributes the water from the water tank 26 to the flood bar ' assembly 30 to thereby be applied to the flood cloth 32 to form the ice surface. ' . , As illustrated in. Figures 2 and 3, one or more magnets 34 axe provided at one or more locations along the delivery pipe z8 and flood bar assembly 30. Tne magnets 34 1 , are attached to the exterior surface of the delivery pipe 28 or flood bar assembly 30 such that the water flowing in the pipes are subject to the magnetic field generated . 25 by the magnets. The magnets 34 are arranged on the pipes such that the north pole is oriented outwardly and the south pale of the magnet is oriented inwardly to the , . , pipe.
Preferably, the magmets 34 are ceramic magnets, as these have been found to be most effective but other types of magnets may be utilized. For example, an energized coil ' , electromagnet or ferrous magnets may also be employed.
It has also been found that the magnetic field effect of the present invention rrtay be ;
enhanced by providing the magnet 34 with a steel ox other ferrous metal backing 38 plate on north pole of the magnet, . The use of the steel backing plate 38 appears to , ' better focus the magnetic field within the pipe.
. . , _4' T!-zz rr3cA
,' There are a number of different locations at which the magnets,34 can be placed to provide far the desired effect on the water flowing through the pipe. The magnets 34 rnay be placed on the delivery pipe 28 to surround the delivery pipe 2$ such that the water is treated by the magttetit field prior to its distribution through the flood bar assembly 30. Alternatively, one or more magnets 34 may be placed along the flood bar assembly 30 such that the water is subjected to the magnetic field just prior to its exiting the flood bar assembly 30 through the openings 36 provided along the length ' of the flood bar assembly 30. Preferably, for a maximum effect, it has been found that a number o~ magnets 34 placed around the delivery pipe 28 as well as magnets 34 placed along the length of the flood bar assembly 30 are most effective for the desired treatment.
- To resurface the ice utilizing the apparatus of the present invention, the operator operates the ice resurtacer i11 the normal manner scraping the i,ce and flooding the ice ' 15 with the thin layer of water applied to the ice through the flood loth.
In operation the water from the water tank 26 is dispensed along the delivery pipe 28 to the flood bar assembly 30 where it exits the flood bar assembly 30 through the openings 36, The water then falls on the flood cloth 32 ~rorn which it is dispensed onto the surface of the ice.

Tt has been found that utilizing the magnets on the delivery pipe and/or flood bar assembly in accordance with the present invention provides numerous benefits to art operator of the ice resurfacing machine. Firstly, the ice prepared utilizing the apparatus of the present invention has been found to be very dense and high quality zS such that ruts formed in the surface of the ice as a result of the skaters movement of the skate blades are not as deep as those formed in ice utilizing a standard ice resurfacer of the prior art. In addition and more importantly, is has been found that this ice may be formed utilizing much lower temperature water than has previously commonly been used in ice resurfacing machines. While Typically the water in a ice 30 resurfacing rrxaclune is heated to about 150°F for the making of ice in an arena, with the apparatus of the present invention, it has been found that water of 90°F or perhaps even less may be utilized to form the dense high quality ice. The ice formed with the apparatus of the present invention has been also found to be nnuch clearer perhaps as a result o~ less dissolved gases wi hin the water. The denser ice also 35 allows for better conductivity of the chilling effect of the chilled floor to the surface of the lee. It has also beer: found that ice formed with the ice resurfacex of the present invention is a faster zce where a skater's movement is quicker. In addition, for .hockey games the puck has been found to move faster on such ice.
_S_ - . ' . 11-~.z 7r~~.
In addition to using the magnets to treat the water applied to an ice surface with an ' ' ice resurfacing machine, the water utilized to build up the original ice layers may also be nta~tetically treated. 'This may be accomplished by providing oxte or more magnets on the hose used to flood the chilled surface to produce the ice layer. The , magnets are preferably provided in a collar either attached to the hose ox tkuough which the hose passes. In this way, the original ice layers are dense and of high ' ' quality, making the resurfacing of the ice much easier.
While it is not exactly known how the magnets iz~creasE the density and quality of the ice, it is postulated that it may be in part due to the magnetic field acting on the . water molecules to reduce the bond angles and allow for denser packing of the water molecules in the ice as it is forming.
