An arrangement of several machine assemblies (34, 38). The machine assemblies are arranged in a way that the material flow between the machine assemblies (34, 38) is at least technically mutually coupled. The machine assemblies are subsequently arranged to form treatment stations and/or processing stations of a machine (10) for processing, treatment and/or filling of containers. A method for coupling several machine assemblies (34, 38). The assemblies are subsequently arranged to form treatment stations and/or processing stations of a machine (10) for processing, treatment and/or filling of containers.

The invention relates to a lubricating pump which contains screw pistons of which one is in compression operation and the other is in suction operation in alternation. The invention further relates to a method for supplying lubricant, wherein a first screw piston is in a suction operation while a second screw piston is in a compression operation and vice versa, and wherein the two screw pistons are driven by means of a common gear train, which contains one piston gear for each screw piston.

Capsules for use in a beverage production machine. One capsule includes a base body having a flange-like rim and containing beverage-forming ingredients therein, the ingredients being sealed in the base body by a foil member attached to the flange-like rim, and at least one flow control porous member arranged between at least a portion of ingredients in the capsule and the foil member. Another capsule includes a first wall member for supporting beverage-forming ingredients, a second perforable wall member attached to the first wall member, and at least one porous layer located between the beverage-forming ingredients in the capsule and the second wall member, with the porous layer forming a multilayer laminate with the perforable non-porous foil member. These flow control porous members provide faster and more consistent flow of the liquid extract through the capsule and significantly reduces the resurgence of non-soluble solids.

A beverage system for selectively delivering, in a same coffee extraction device, short coffee liquid extracts and long coffee liquid extracts comprising: cartridges containing ground coffee; a receiving device for receiving one cartridge at a time and pumping means or injecting water under pressure in the cartridge; means for opening the cartridge wherein these means comprises retaining means to retain the liquid under pressure in the cartridge and engaging means which engage the retaining means to open the cartridge and deliver the coffee liquid extract; wherein the system comprises at least a first cartridge adapted to deliver a short coffee liquid extract, wherein the system comprises at least a second cartridge which has substantially the same external configuration and shape as the first cartridge so as to be capable of being received in the same receiving device as the first cartridge and which is adapted to deliver a longer coffee liquid extract upon allowing a larger amount of water to flow there trough, wherein the second cartridge for the longer coffee liquid extract is configured so that water flows through it at a higher rate than in the first cartridge during extraction.
摘要:
A method is provided for the electronic scanning of the intensity distribution of an optical interference pattern by means of a linear image sensor, wherein the interference pattern is produced by overlapping two temporally partly coherent beams striking at an arbitrarily predefined angle α in relation to one another and is provided with an interference strip having a carrier frequency greater than the scanning frequency, and amplitude modulation that can be varied slowly in relation to the pixel width, wherein at least one optical grating is disposed in the beam path of at least one of two incident beams and the image sensor is disposed in the diffraction image of the grating(s) such that, at the site of the image sensor, the beams interfere, and the beams enclose an angle β at the site of the image sensor, the angle being smaller than α.
摘要:
The invention relates to an arrangement for cooling equipment and network cabinets, particularly server cabinets, in which the fans are integrated into a door. The resulting fan door, in the closed position, covers an access area of the rear of the cabinet and longitudinally adjacent to the fan door is arranged in fixed manner an air-to-fluid heat exchanger, whilst covering a residual area of the rear of the cabinet and to which is articulated the fan door. The heat loss given off to a cooling liquid, particularly cold water, in the heat exchanger is removed via a pipe system outside the cabinet installation area and rigid connecting pipes of a gas-tight material can be used for the connection of the heat exchangers of the individual cabinets to the building-side pipe system.

The device serves the change of the length of the running path of an electromagnetic wave, and specifically of a light beam between the emitter and receiver. It comprises two oppositely lying reflection means between which the beam is reflected, as well as a means for changing the distance of these reflection means. The reflection means are arranged at an angle &bgr; to one another which lies between 0° and 45° so that the incident beam is thrown to and fro several times between the reflection means, until it is finally congruently thrown back.
