Abstract: A training apparatus for teaching and practicing skills for sports. The apparatus includes at least one removable electronic device having at least one proximity sensor, a playing surface having a cavity which receives the at least one removable electronic device, and a gamepiece, such as a ball. Each proximity sensor is adapted to sense the gamepiece and activates a visual or audio indicator on the at least one removable electronic device if the gamepiece is within a range of the at least one proximity sensor.

Abstract: A snow making system, suitable for making man-made snow for ski-runs or ski-slopes, uses a snow making machine, where ice is converted into snow-like particles and directed in an upwardly-directed stream, into which a spray or mist of water droplets is introduced. The snow-like particles operate as nucleating agents for the water droplets to convert the droplets into flakes of snow. The flakes of snow may be introduced into the snow making machine, converted into snow-like particles and be incorporated into the stream to produce further flakes of snow. The flakes of snow can be “recycled” to the snow making machine until the desired quantity of snow has been produced. The system enables snow to be made at ambient air temperatures just above, or below, the freezing point of water.

Abstract: A frozen beverage device to convert a liquid beverage into a semi-frozen or frozen form has inner and outer walls forming at least one refrigerant cavity containing a refrigerant material with a freezing point below the freezing point of the liquid, the refrigerant material occupying at least 60% of the volume of the refrigerant cavity. The walls of the device can be squeezed to accelerate the heat transfer from the liquid to the refrigerant material; and the device may be placed in a squeezing apparatus. Where the device is to be disposable, the device can be placed in a flexible sheath or outer container before being squeezed to protect the device and/or insulate the user from the refrigerant material. A freezing spoon or stirrer can be used to assist, or accelerate, the freezing process.

Abstract: A system for producing snow incorporates a snow-making machine with ice supplied externally or manufactured on-site. The snow-making machine has one or more multi-bladed impellers fitted blades which impact ice blocks, pieces or tubes fed to the inlet of a snow-making chamber. The impact of the blades with the ice in a velocity range 150-300 Km/h produces artificial snow, with characteristics very similar to natural snow, suitable for ski-fields or other applications for snow. The blades may incorporate serrated or jagged cutter portions the break the latter ice pieces to sizes suitable for conversion to snow.

Abstract: A frozen beverage device to convert a liquid beverage into a semi-frozen or frozen form has inner and outer walls forming a refrigerant cavity containing a refrigerant material with a freezing point below the freezing point of the liquid, the refrigerant material occupying at least 80% of the volume of the refrigerant cavity. The outer wall has a base portion which can be moved from a first position, where the liquid is at least semi-frozen, to a second position where the internal pressure in the refrigerant cavity urges the inner wall outwardly towards the outer wall so that the refrigerant material contacts a maximum area of the surface of the inner wall in the refrigerant cavity for maximum heat transfer and to minimise constriction of access to the frozen beverage. Alternative methods to seal the inner and outer walls to close the refrigerant cavity are also disclosed.

Abstract: A frozen beverage device (10) has a container (20) and sealable cover (30) to convert a liquid (60), such as a non-alcoholic or alcoholic beverage into an at least semi-frozen slurry containing ice crystals (61). Freezing device(s) (50), which may have a range of shapes, contain refrigerant to from a thin layer of ice/ice crystals on the deformable wall(s) of the freezing device(s) (50), the ice crystals (61) being released therefrom due to agitation of the liquid (60) by shaking/rotation and/or squeezing on the container (20) and/or cover (30).
