Abstract:
A system and a method of providing PUR/PIR foam using flammable blowing agent. The flammable blowing agent is introduced to PUR/PIR manufacturing equipment via an independent feed-line. This enables a flammable blowing agent storage vessel to be located off site from the foam manufacturing equipment. The independent flammable blowing agent feed-line couples the off-site flammable blowing agent storage vessel with the foam production system. The preferred flammable blowing agent is pentane.
Abstract:
The invention relates to a safety device for a blender that consists of a blending container (10) which is placed on a base (7) that is equipped with a drive motor. The safety device has two vertically moveable actuating pins (1) which are arranged at a distance from each other and which protrude upwards through the wall of the base (7). The blending container (10) has corresponding actuating points (11) which simultaneously, evenly push the two actuating pins (1) downwards, horizontally when the blending container (10) is correctly positioned on the base, hereby closing the circuit that supplies the drive motor. Maloperation or the driving of the motor when the blending container (10) is not correctly positioned on the base is avoided by means of actuating members in the base (7) being connected to the actuating pins (1) in such a way that a safety switch only closes when the pins (1) are pushed down horizontally, simultaneously and evenly.
Abstract:
The safety and injection system (S) according to the present invention and for adding an additive into the fuel available in a fuel chamber (R) comprises a portable additive source (P) which has a body (9), an additive chamber (5) in which the additive to be added into the fuel is stored, a memory (6), a fuel inlet (7) and a fuel outlet (8) connected to the additive source (5); a fuel inlet valve (3) which is connected to the fuel chamber (R), which comprises at least one connector for connecting to the fuel inlet (7) and which supplies the fuel received from the fuel chamber (R) into the additive chamber (5) through the fuel inlet (7); a fuel outlet valve (4) which is connected to the fuel chamber (R), which comprises a connector for connecting to the fuel outlet (8) and which supplies the additive in the additive chamber (5) and the fuel from the fuel inlet (7) into the fuel chamber (R); a platform (1 ) which has a memory reader/writer (2) that reads the information in the memory (6) and is capable of writing information on the memory (6) and on which the said portable additive source (P) is placed; and at least one control unit which is connected with the memory reader/writer (2), which comprises a user interface device for receiving control information from the user, and which controls the operation of the safety and injection system (S).
Abstract:
Misch-, Rühr- oder Dispergierverfahren mit einer entsprechenden Vorrichtung (1) mit einem Gehäuse (2) und einem Behältnis (3). Das Behältnis (3) weist einen Mischraum (4) auf, in welchen Mischraum (4) ein stabförmiges Element (6) hineinragt. Am Eintritt in den Mischraum (4) ist dieses stabförmige Element (6) mit einer Membran (8) verbunden, welche Membran (8) Teil einer Wandung (9) des Behältnisses (3) ist. Zur Bearbeitung des Inhalts des Mischraums (4) wird das stabförmige Element (6) gemeinsam mit der Membran (8) durch einen Antrieb (7) in Bewegung versetzt. Zur Vermeidung eines unbeabsichtigten Versagens der Membran (8) wird im Rahmen des Verfahrens die Anzahl der Umdrehungen des Antriebes (7) gezählt und dieser bei Erreichen einer für die Belastbarkeit der Membran (8) zulässigen Höchstzahl von Umdrehungen und daraus ableitbaren Anzahl von Lastwechseln abgeschaltet.
Abstract:
L'invention concerne un dispositif (1) de formation de gouttes dans un circuit microfluidique, comprenant une chambre (3) contenant un premier fluide et délimitée par deux parois opposées (10, 11) qui divergent l'une par rapport à l'autre dans au moins une direction donnée, et un microcanal (8) qui contient un second fluide et qui débouche dans une zone amont de ladite chambre (3) par rapport à la direction donnée, le débouché du microcanal (8) dans la chambre (3) constituant un élargissement de la section de passage du second fluide et cet élargissement provoquant la formation de gouttes (14) du second fluide au sein du premier fluide.
Abstract:
A mixing machine includes a base, a head including a rotatable output member for receiving a mixer tool and a support column extending vertically from the base to the head. A bowl receiving assembly is below the head. The bowl receiving assembly is configured to move vertically along the support column and defining a bowl receiving location. A bowl lock assembly includes a moveable bowl lock member carried by the bowl receiving assembly and having an unlock position and a lock position. The bowl lock assembly is configured such that placement of the bowl lock member in the unlock position or the lock position depends on a vertical position of the bowl receiving assembly.
Abstract:
The invention refers to an agitator for agitating at least one liquid or solid material and/or mixing and/or dissolving at least two liquid and/or solid materials with a drive-stirrer shaft and at least one stirrer connected to the drive-stirrer shaft, wherein the at least one stirrer can be driven in a working state for stirring, mixing and/or dissolving the materials via the drive-stirrer shaft by means of a driving motor. Additionally, the agitator provides a creep speed motor and the at least one stirrer is driven in a creep speed state via the drive-stirrer shaft by means of the creep speed motor only, wherein the creep speed motor features a lower power output than the driving motor. The invention also refers to a respective method for cleaning an agitator.
Abstract:
In the method for venting and eliminating liquid material of a dispensing appliance prior to dispensing, the air as well as unusable material are eliminated via a deviating channel and the conditioned material is dispensed via a dispensing channel. The device (6) for implementing the method for eliminating unusable liquid material and for venting a dispensing appliance is provided with a valve assembly (8) for selectively connecting the inlet area of the device with a deviating channel (15) or with an outlet (9). The deviating channel is connected to a collecting container having venting means (7). The method and the device according to the invention allow advantageously venting a multicomponent dispensing appliance and leveling the components as well as eliminating incompletely mixed components in the starting phase after the latter have left the mixer elements, thereby ensuring a flawless application. In an advantageous development, a device (102) is provided that avoids the occurrence of an overpressure during dispensing.
