摘要:
A molybdenum silicide type-heating element and a method of manufacturing a heating element of the molybdenum silicide type. The heating element contains substantially Mo(Si1-x Alx)2 and Al2O3 and is prepared by mixing a molybdenum aluminum silicide-type material Mo(Si1-yAly)2 with SiO2, wherein the SiO2 has a purity of at least 98%.
摘要:
A method for the production of a heating element that is composed essentially of molybdenum silicide and alloys of that basic material, and a heating element formed from such material. A material is produced that contains substantially Mo(Si1-xAlx)2 and Al2O3 by mixing a molybdenum aluminum silicide Mo(Si1-yAly)2 with bentonite clay in a known manner. The bentonite clay contains impure or contaminating substances with which molybdenum silicide cannot be alloyed and with which the symmetry of the crystal lattice of the molybdenum silicide is retained with a combined content of less than 2000 ppm.

Electric connecting device for electrically controlled, so called pilot valves (21-25) connected to a corresponding number of valves (1-5) in a modular valve array. Each pilot valve has equally placed contact pins (26,27,28), which are connected to a common, flexible connecting cable (29) with a plurality of conductors (29) over an electric connecting module (30). Each connecting module (30) is constituted by a coupling plate (32) provided with on the one hand contact sockets (33,34,35) for connection to said contact pins (26,27,28) of the respective pilot valve, and on the other hand a multipolar contact means (37), which is connectable to a corresponding cable contact means (38), which is connected to conductors of the common connecting cable (29). The coupling plate (32) is provided with an array of preferably controllable electrical connections (36) for the desired connection between said multipolar cable contact means (37) and said contact sockets (33,34,35).
摘要:
Method and devices intended to be used at sensing of breathing of a man or an animal in order to with a breathing sensor securely sense the breathing regardless of whether it occurs through the nose or mouth. A device (1) conducts breathing air flows to and from the nose as well as the mouth past a position (5), at which the sensor is located. In one embodiment the device is tubular and has two orifices (2, 3) for location at the nose and mouth respectively, as well as a third orifice (5) onto which a sensor may be fastened by snap action.

The present invention relates to a height-adjustable table stand (1) comprising a height-adjusting arrangement for adjusting the height of the table, wherein the height-adjusting arrangement comprises at least one leg (2), each leg having an inner tubular member (3) and an outer tubular member (4) arranged for telescopic movement relative to each other. The height-adjusting arrangement further comprises a linear actuator coupled to said tubular members (3, 4) and adapted to provide the telescopic movement between the tubular members, an electric motor (12) connected to the linear actuator and adapted to operate the linear actuator for providing telescopic movement between the tubular members, and a control device (13) for controlling the operation of the electric motor (12). The table stand (1) further comprises a solar panel (10) connected to the height-adjusting arrangement for providing power to the electric motor (12).

A linear actuator (1), comprising a threaded spindle (10) with a longitudinal extension along a longitudinal axis (X), the spindle (10) having a right hand thread (11) and a left hand thread (12), both threads provided over a common longitudinal length of the spindle, the spindle (10) being adapted to be rotated by a driving device (60). The linear actuator further comprises a first nut member (20) provided with a right hand thread (21) and a second nut member (30) provided with a left hand thread (31). The first and the second nut members (20, 30) are in threaded connection with the spindle (10) in such a way that rotation of the spindle provides opposite linear movement of the nut members (20, 30) relative to each other along the longitudinal axis (X). Thereby, a linear actuator is provided with three parts that all move linearly relative to each other during rotation of the spindle.

摘要:
We present an optical probe arrangement that surrounds blood in a receptacle. It comprises LED's and light detector arranged to overcome the variations when the receptacle is translucent medical tubing and the like. Also, a signal processing algorithm is used to average signals from a plurality of light detectors, to further enhance results when measuring hematocrit. The invention makes it possible to add the feature of hematocrit measurement into dialysis system without major alterations to the dialysis machine or transport tubing.
