The fuse is thermally coupled to pole pieces of the assembly and is in electrical circuit with the coil.

Abstract: Electromagnet system for influencing a dipper armature forms part of a closing unit. A solenoid coil with a U-shaped magnetic core for influencing a dipper armature is mounted on a cylindrical core and has on each end a flat pole piece, each of which is connected to the cylindrical core so as to be connected mechanically and conduct magnetically. The U-shaped magnetic flux element of the electromagnet system is mounted with its two pole pieces on support bars of the recipient housing. Stop lugs are mounted on the field spool and are locked in position with appropriately shaped parts of the recipient housing.

Abstract: A refrigeration apparatus includes a cooling chamber having a given useful space therein, and a cold generator having a cold air loop connected to the cooling chamber for cooling the given useful space, the cold air loop including a compressing device, a heat exchanger disposed downstream of the compressing device and exposed to the ambient air for cooling air drawn from the useful space with a relatively high temperature level almost to the temperature of the ambient air after compression, cooling device downstream of the heat exchanger, an expansion device downstream of the cooling device, the air being returned to the useful space after subsequent expansion and corresponding cooling below the lowest temperature level, and an additional heat exchanger for dehumidifying the circulated air current in the loop, the additional heat exchanger including heat exchanger surfaces, air drawn from the cooling chamber being dried from the upper temperature level with the aid of expanded cold air by the of condensation

Abstract: Apparatus for supplying water to a carbonator tank in a liquid dispensing system includes a water supply delivery control circuit which generates a periodic supply enabling signal of a relatively short duration when the water level in the tank falls below a predetermined level and an enabling signal of a comparatively longer duration when an initial filling of the tank is desired or a system reset switch is manually activated. Both periods are selected so as to prevent damage to the delivery pump, for example, due to an overload condition caused by an interruption of the water supply.

Abstract: A disposable syrup package for use in a post-mix beverage dispenser including a collapsible bag for containing the syrup; a discharge spout extending from the bag; and a break-away proportioning insert in the spout, which is broken when a dosing valve assembly is attached to the spout. The package structure substantially precludes the refilling and reuse thereof.

Abstract: A water-carbonation system having a pressurized tank which is preferably cooled, a water supply and a CO.sub.2 gas supply. The CO.sub.2 gas supply has a pressure-reducing valve assembly in the supply line. The valve of this assembly is maintained in a closed position by the gas pressure in the tank. However, when this pressure falls below a predetermined limit, the valve will move to an open position to vent the tank to the atmosphere. A signal may be used in conjunction with the valve to notify an operator of the drop in pressure. The valve may also be manually operated to vent the tank. This water-carbonation system can be used in beverage dispensers in which the carbonized water is mixed with beverage concentrates to prepare a beverage that is ready for consumption.

Abstract: A circuit for the control of a refrigeration circuit for at least two refrigeration areas such as the carbonated water supply and beverage concentrate chamber of a beverage dispenser. Priority cooling of one area is achieved by use of a combinational logic circuit in conjunction with refrigeration-requirement sensors so that the CO.sub.2 water supply will be cooled first regardless of a requirement for the cooling of the concentrate chamber.

Abstract: An easy to use system for connecting a bottle-type, gas containing pressurized vessel to a gas-withdrawal unit includes a valve assembly mounted on the pressurized vessel. A longitudinal axis of this valve assembly is substantially perpendicular to a longitudinal axis of the pressurized vessel resulting in an offset outlet design. The system also includes a housing with slotted links for guiding and holding the pressurized vessel as well as a centering device located in front of the gas-withdrawal unit for aiding alignment of an outlet of the valve assembly with an inlet port of the gas-withdrawal unit. A pivot lever is also provided to press and hold the outlet of the valve assembly gastight against the inlet port of the control unit.

Abstract: A beverage vessel, includes a receptacle formed of vitreous material, a handle, and a layer of adhesive material fastening said handle to said receptacle.

Abstract: Container assembly for beverage concentrates, including a container having an opening formed therein, a carrier disposed in the opening, a membrane-type seal disposed in the opening sealing the carrier to the container, a reusable measuring device having an end section for attachment to the container at the opening, at least one tab projecting from the end section for punching through the seal, and at least one barbed hook disposed on the at least one tab being solidly snappable-in on the carrier when attaching the measuring device to the container at the opening, the measuring device being detachable from the container after being attached exclusively by pulling the carrier from the opening.

Abstract: Cooling appliance, including a housing having an opening formed therein, at least one door for sealing the opening, at least one first bearing part fixed on the housing in vicinity of the opening, at least one second bearing part being movably disposed on the first bearing part, at least one supporting tray disposed in the housing and having a given region being disposed on the at least one second bearing part, the supporting tray having a curved portion opposite the given region for permitting the tray to be at least partly swung out of the housing when the door is open, damping means disposed on the tray opposite the housing for damping the impact thereof when swung into the housing, and retaining means disposed on the tray opposite the housing for catching the tray when swung into the housing.

Abstract: Automatically operating washing machines adjust the washing time, the wash water temperature and the motion, i.e. agitation, of the laundry based on predetermined cycles, such as wash, spin, or rinse, etc. An adjustable program course controls these cycles. Naturally, certain cycles require hotter or colder temperatures than others. The method of the invention varies the program course to cycles requiring hotter or colder temperature, depending on the temperature available. Therefore, if a cycle requires hot water but only cold water is available, another cycle will be chosen or the cycle will run for a shorter time. The automatically operating washing machine has at least one cold water inlet and at least one warm water inlet.

Abstract: A fluid timing element, comprising a nozzle, a needle being at least partly insertable into the nozzle forming a choke gap therebetween, at least one of the nozzle and the needle being axially tapered, the nozzle and the needle being axially movable relative to each other for adjusting the choke gap, the nozzle and the needle having different cross-sectional shapes and having at least two wall sections distributed over the peripheries thereof projecting into and constricting the choke gap.
