A Multi Port Extrusion tubing (MPE tubing) () made from a Multi Port Extrusion (MPE), the MPE being a web like extrusion (Web-MPE) with two or more individual tubes () interlinked with webs (). The webs have a thickness, which is less than the tube diameter of the individual tubes, and the MPE tubing includes at least one bending zone (A), and at least two straight zones (C, C). The web-MPE in the bending zone (A) is bent so that each individual tube has a U-shape, and the web-MPE in a first straight zone (C) is parallel to the web-MPE in an adjacent second straight zone (C). The web-MPE in the straight zones on each side of the bending zone (A) extend in substantially the same plane, so that all individual tubes of the web-MPE in the straight zones are parallel to each other, and extend in the same plane.

A method for controlling a refrigeration system with a variable compressor capacity, and at least two refrigeration entities, e.g. display cases, includes controlling suction pressure by either permitting or preventing the flow of refrigerant into the evaporators of one or more refrigeration entities. The method also includes controlling compressor capacity based on a signal derived from one or more properties of the one or more refrigeration entities, said signal reflecting a possible difference between the current compressor capacity and a current refrigeration demand of the refrigeration system. The method reduces wear on compressors by avoiding switching them ON or OFF to the largest extent possible, and also prevents problems relating to conflicting control strategies due to control parameters, e.g. suction pressure, being determined based on two or more controllable parts, e.g. compressors and flow of refrigerant into refrigeration entities.

Method for controlling a refrigeration system

A method for controlling a temperature in a refrigeration system using a quality decay value expressing an expected decay rate in quality of the products being refrigerated, and which depends on the temperature of air present in the refrigeration system. The quality decay value is obtained using a mathematical model reflecting one or more physical and/or biological processes in the products. Prevents or reduces the quality degradation of the products in terms of shelf life, appearance or tastiness. Furthermore, a method for controlling the temperature in such a way that effects of scheduled events, such as temperature increase during defrosts, can be compensated prior to the event.

It is known to make the performance of a loudspeaker 'environment adaptive' in controlling a filter unit based on a measurement of the velocity/acceleration of the loudspeaker diaphragm and the associated sound pressure in front of the diaphragm, by means of an accelerometer and a microphone, respectively, thereby determining the radiation resistance of the diaphragm. The two sensors have to exhibit a constant transfer function throughout the life time of the loudspeaker, which make them very expensive. With the invention it has been found that the accelerometer can be replaced by another microphone held in a small distance from the diaphragm, and this conditions the possibility of using the same microphone for both measurements, e.g. simply by physically moving the microphone from one position to another. It will then no longer be required to use long-time stable sensors, whereby the price of the sensor equipment can be reduced dramatically. Also alternative arrangements are disclosed.

A control system for a hydraulic servomotor () is disclosed. The control system comprises an electro hydraulic actuator () comprising a number of valves () for controlling fluid flows, a main control module (), and one or more connectors. The control system further comprises at least one extension control module () comprising one or more connectors. Finally, the control system comprises means () for communicating signals between the main control module () and each of the extension control module(s) (). Since the main control module () and the extension control module(s) () are able to communicate signals, it is possible to provide signals to/from the main control module () via an extension module (), thereby in effect providing additional connectors to the main control module (). Thereby the main control module () may be able to perform additional functions as compared to similar prior art control modules.

Control system for a hydraulic servomotor

A hydraulic actuator for a hydraulic servomotor () is disclosed. The hydraulic servomotor () is of a kind having at least one defined end position, and has a first chamber () and a second chamber () associated therewith. The actuator is connected to a fluid source () and a fluid drain (). The actuator comprises a first valve () fluidly connected between the fluid source () and the first chamber (), a second valve () fluidly connected between the first chamber () and the fluid drain (), and a third valve () fluidly connected between the fluid source () and the second chamber (). The actuator further comprises a flow channel (), preferably comprising a flow restrictor (), in fluid communication with the second chamber (). The valves () are such that, in the case of a power cut off, they will prevent a fluid flow out of the first chamber (), and a fluid flow out of the second chamber () takes place via the flow channel (). This will cause a servomotor piston member () to move towards the second chamber (), thereby moving the hydraulic servomotor () to an end position.

An axial piston micropump is disclosed, having a cylinder drum, in which several cylinders are provided a swash plate, with respect to which the cylinder drum is rotatable. It is desirable for such a micropump to have a small displacement combined with a long service life and in which the displacement or delivery volume can be achieved with great accuracy. For that purpose, at least two cylinders are provided, of which at least one is in the form of a working cylinder which has an associated working piston, while at least one other cylinder is in the form of a balance cylinder and has an associated balance piston.

Analysis apparatus

Distributor device, in particular for a chemical analysis arrangement

An analysis method is disclosed, in which several samples are passed in succession through a reaction channel to a detector (17), and at least one reagent is introduced into the reaction channel (16) for reaction with the samples. An apparatus for implementing the method is also disclosed. Using the method and the apparatus, it is intended to specify an analysis method more capable of coping with different flow characteristics of the samples in fluid form. For that purpose, each sample and its associated reagent is introduced in a controlled manner into the reaction channel so that they form a block, along the length of which the local volume ratio between sample and reagent, averaged over a segment of predetermined length, is substantially constant, the length of the segment being substantially shorter than half the length of the block.

The invention relates to a device and method for regulating the superheat temperature of the evaporator of a refrigeration or heat pump system. The existing and desired superheat values are compared at intervals of two and the rate of departure between these two values is utilized for adjusting the desired superheat value.
