Dewatering device and process of a machine for at least one of production and processing of a material web, as well as a glazing device an process. The dewatering device includes a circulating flexible continuous belt and an opposite surface. The circulating flexible continuous belt and the opposite surface are arranged to form a nip elongated in a web travel direction, and at least one screen is adapted to guide the material web through the nip. A saddle, which is arranged to support the circulating flexible continuous belt, is segmented in the web travel direction into saddle segments connected to each other. The saddle segments are at least partially separately pressurized. The dewatering process includes guiding the material web through the nip, and at least partially separately pressurizing the saddle segments against the opposite surface. The glazing device includes a heated roller composed of a saddle roller and a mating roller, and the heated roller and the mating roller are arranged to form a nip elongated in a web travel direction. The saddle roller may include a flexible roller jacket supported by a saddle which is segmented in the web travel direction into saddle segments connected to each other. The saddle segments are at least partially separately pressurized. The glazing process includes guiding the material web through the nip, and at least partially separately pressurizing the saddle segments against the mating roller.

Headbox of a paper machine and a process of supplying a material suspension, The headbox includes at least one material suspension supplying system, and a headbox nozzle that includes a first dividing wall having a machine width and a second dividing wall having a machine width. The first and second dividing walls are arranged to form a first path in which a total nozzle cross-section steadily and continually decreases in a material flow direction and to form a second path, arranged to follow the first path, in which a total nozzle cross-section continually increases in the material flow direction. The process includes includes accelerating the material suspension along a first path having a total nozzle cross-section that steadily and continually decreases in a material flow direction, and decelerating the material suspension along a second path having a total nozzle cross-section that continually increases in the material flow direction. The second path is arranged to follow the first path.

The invention describes a method for the modulation of the light intensity of fluorescent lamps via the supply main by modification of the form and/or the amplitude of the power supply provided. An electronic control element, provided as a component of the logical circuit, temporarily blocks current flow after at least every second zero-crossing of the voltage, dependent upon time and/or voltage. Blocking of the current flow occurs only during the time period in which there is no flow of charging current for the downstream direct-current mains supply circuit. The advantage thus obtained is that the control pulses for the logical circuit do not influence the electric current flowing through the fluorescent lamps.

A process and equipment for safeguarding the operation of gambling machines with electronic cards in a manner that protects against counterfeiting and fraud. The microchip cards are numbered and a central computer stores at least the amount paid in for playing under the particular card number upon issuing the card. A card is inserted in a gambling machine, which has a read/write unit that compares the amount available for playing with the credit stored under the respective card number in the central computer before releasing the gambling machine for playing. Only if the two amounts match is the machine released for playing and the prevailing credit balance for the card is transmitted continuously during play to the central computer.

A method of producing durable, structurally strong, investment quality gold articles of high troy weight, excellent color and revealing properties and the method of their production are described, including the formation of a structural base from an alloy containing not over 8.33% of a strengthening material such as chromium, titanium or vanadium, which can provide the required strength and hardness in low concentrations, and overlayment or "overarching" with a gold alloy coating in a manner such that both alloys are visible. The structural base provides the support, strength and resistance to corrosion in articles of various shapes, while retaining a high degree of gold purity.

A compact fluorescent lamp including one lamp with one or more tubular lamp members, and an electronic ballast constructed as a unit separate from the foregoing, which constituting an adapter, is electrically and mechanically connectable with the lamp by means of a plug-in connection. In order to achieve the smallest possible length of the compact fluorescent lamp, the plug-in connection between the lamp and the ballast, extends in the direction of the lamp at least partially into the space surrounded by the lamp.

According to this invention, cold is conveyed into a cooling chamber by means of convectors, and fresh air of a higher temperature is supplied in a controlled manner so that the temperature decreases. To avoid power loss due to the quantity of heat supplied, the displaced cold air is channeled towards a heat exchanger in the condenser of the cooling machine. Since the fresh air which circulates is always above 0.degree. C., the humidity content of the fresh air supplied can be controlled and be filtered to remove odors.

In a grip-less water mixer unit, the quantity of water outflow and the mixing temperature are controlled by pivot-mounting the water outlet about two independent axes in a valve body. The water outlet is coupled to two regulating elements of which, one serves to regulate the water quantity and the other the adjustment of the mixing temperature. In a first embodiment example both regulating elements are formed as cylindrical bodies rotatable in the valve body, and in a second embodiment example, both regulating elements are concentrated in a ball which is rotatable in the valve body.

Fittings for adapting conventional fluorescent light fixtures to receive smaller-diameter T5 fluorescent tubes are described. The fittings include transparent tubes adapted to fit around the small-diameter T5 light, electronic components for supplying high-frequency current, and insulation caps having pins which correspond to the receptacle for the lamp that is being replaced.
摘要:
A method and device for controlling electric discharge lamps with electronic fluorescent lamp ballasts, using a bistable reverse switch system in the electric circuit in such manner that in turning the lamp on to a first switching condition, and after a short period of interruption of the electric circuit to the current supply of the lamp, the bistable reverse switch system acquires a second switching condition. It is thereby possible to reduce the lamp from a first level of brightness to a second lower level of brightness. It has the effect of a "dimmer" used with fluorescent lamps.
