Abstract: A communication system includes a browser system coupled to a communication network. A first server system is coupled to the communication network and has a plurality of first processes and a first proxy group. The first proxy group has a first shared memory and a first proxy. The first shared memory has a plurality of first slots, each first slot being assigned to one of the plurality of first processes and configured to store data transmitted by or to be received by the assigned first process. The first server system further includes a plurality of process mark devices and a single proxy mark device to regulate the data flow of the first proxy group. A second server system is coupled to the communication network and has a plurality of second processes and a second proxy group. The second proxy group has a second shared memory and a second proxy, wherein the first proxy and the second proxy are configured to form a communication link with the other.

Abstract: A drinking vessel 38 in which a beverage, for example a draught beer, is to be served is cooled by formation thereon of ice formed of frozen potable liquid for example a small volume of the same beer. The potable liquid can be sprayed at 40 onto the inside 42 of the vessel 38 and/or onto the outside 44 of the vessel, and the liquid is then frozen on the vessel wall by the effect of a cooling coil 28 surrounding the vessel which can be rotated by a rotatably driven platform 30. The cooled vessel 38 will in turn cool beverage dispensed into it for drinking.

Abstract: A beverage, for example a draught beverage, which may already be cooled before introduction into a drinking vessel is introduced into the vessel into which additional cooled material is introduced. The cooled material may be frozen water which is used to dilute the beverage to a desired strength e.g. a desired alcoholic strength. Alternatively the cooled material may be frozen beverage.

Abstract: A font 2 to be mounted on a counter of a drinks bar to dispense draught beverage has a cantilever shaped body 6 with two ascending legs 8 which are either side of a through opening 4 and rise from a base 16 to an overhanging head 9 provided with a beverage dispenser nozzle 10 through which the beverage issues upon operation of lever 12. The base 16 has a rotatably driven platform 14 on which a drinking glass 20 stands to be filled. The font can have various lights to illuminate the glass which can be seen by a customer looking in direction. A through the opening 4 from a side of the font remote from the platform 14.

Abstract: A method of dispensing a draught beverage, for example a beer, having a water content and a dissolved gas content; the beverage issuing from a mixing nozzle 24 into a drinking glass 26. The beverage is subjected to nucleation causing nucleation sites to occur in the beverage, at which sites ice is encouraged to form. Draught beverage from a beverage supply 12 is initially cooled by chiller 16 before reaching the mixing nozzle 24 in which the beverage mixes with coolant from a coolant supply 14 before going into the glass 26. This mixing and cooling by the coolant in the mixing nozzle causes nucleation and ice to form in the beverage before it is delivered into the glass. The coolant may be cold liquified gas, for example liquid nitrogen, or may be solid carbon dioxide.

Abstract: A method of dispensing a draught beverage which may be alcoholic, for example a lager, and having a water content and a dissolved gas content in which the beverage which may be prior chilled, issues into a glass 2 from a nozzle 3 supplied by beverage supply line 4. Mechanical shear is induced in the beverage in the glass 2 by rotating paddles 23 of a stirring device 21 driven by a motor 24. The occurrence of shear can cause nucleation sites to develop in the glass at which sites gas bubbles can form and encourage the formation of ice in the beverage.
