摘要:
A guiding device for the rolling means in a basin rolling assembly, comprising a guide path (6) following the shape of the periphery of the basin and a support element (7) for the rolling means movable on rollers (8, 9, 12, 13, 14, 15) along the guide path. In order to guide the support element exactly along the guide path, a roller (13) running along the inside of the guide path is rigidly mounted in the support element. Along the outside of the guide path run two rollers (14, 15) located one after the other which are mounted to a jaw (16) which is movable with respect to the support element (7) in the radial direction of the guide path (6) and which, by means of its shanks, determines the angular position of the support element (7) with respect to the guide path. The guiding device is moreover provided with a resilient member (23) under the action of which the rollers (13, 14, 15) resiliently abut against the inside and outside of the guide path (6).

The means (10) in milk gathering from milk producers taking place with the aid of tank cars comprises a flexible suction tube (13) or a suction pipe (11) and a flexible suction tube (13), an air separator (14) provided with a venting means (15), a pump means (18) and a volume meter (20). The means (10) is employed to draw the milk from a farm tank or from a milk can to the air separator (14), whence the milk is further conducted to the volume meter (20). With a view to avoiding technical problem solutions having a detrimental effect on the accuracy of measurement, the pump means (18) has been so disposed with reference to the air separator (14) that the air separator (14) is located on the intake side of the pump means (18). The pump means (18) has been provided with a control system (23) adapted to control the pump means (18) in such manner that when the milk surface reaches in the air separator (14) a first upper level (B) the pump means (18) is switched to operate at a slow pumping rate. When the milk surface in the air separator (14) reaches a second upper level (C) higher than the said first upper level (B) the pump means (18) is switched to operate at a higher pumping rate. The operation of the venting means (15) is so controlled with a control means (22) that the venting means (15) is switched to operate when the pressure in the air separator (14) is higher than a predetermined limit pressure (Pr), which is lower than atmospheric pressure. The control system (23) stops the pump means (18) when the milk surface in the air separator (14) falls to a lowest level (A).
摘要:
Die Erfindung betrifft eine Hohlladung mit gerichteter Sprengwirkung. Die Hohlladung (1) umfaßt ein den Sprengstoff (3) aufnehmendes Gehäuseelement (2), eine an dem einen Ende der Hohlladung (1) angebrachte Sprengkapsel (4) und einen am gegenüberliegenden Ende der Hohlladung gelagerten Metallkonus (5). Das Gehäuse (2) und der Metallkonus (5) der Hohlladung (1) sind auf einer gemeinsamen Symmetrieachse (6) genau zentriert, wobei auch die Sprengkapsel (4) auf dieser Symmetrieachse (6) angeordnet ist. Um zu erreichen, daß bei Explosion der Hohlladung die Massenelemente des Metallkonus eine im wesentlichen einzige, geschlossene Stoßmasse hoher Geschwindigkeit erzeugen, ist die Form des aus reinem Metall, vorzugsweise Kupfer, bestehenden Konus (5) der Hohlladung (1), aus der Blickrichtung des zu sprengenden Ziels gesehen, derart parabolisch oder hyperbolisch ausgebildet, daß der auf der Konkavseite des Konus gemessene Konuswinkel (2a) größer als 120° und kleiner als 180° ist. Die Konuswand weist über den gesamten Konusbereich eine gleichmäßige Dicke auf. Aufgrund dieser Ausgestaltung des Metallkonus (5) sind bei Explosion der Hohlladung (1) die Bewegungen der Massenelemente des Metallkonus in der Richtung der genannten Symmetrieachse (6) soweit, wie dies in der Praxis möglich ist, konstant.
摘要:
The invention concerns a procedure in collection of comestible liquids and particularly in milk collection with the aid of tank lorries from milk producers. The comestible liquid is conducted through a suction tube or equivalent to an air separator, where the air in the comestible liquid is separated, and from the air separator (9) the comestible liquid is conducted to a metering device (18), which meters the quantity of comestible liquid that has been caused to flow. The comestible liquid is then conducted along a passage (16) to a tank (1). In the procedure of the invention the comestible liquid is caused to flow from the air separator (9) to the volumetric metering device (18) along the flow line (16) without any pump means inserted in said flow line (16). The flow of comestible liquid in said flow line (16) is controlled with the aid of a valve means (14) inserted in said flow line (16) in a manner known in itself in the art, the liquid level height of the comestible liquid in the air separation tank (9) having been arranged to control said valve means. The invention also concerns apparatus applying the procedure.
摘要:
Selon un mode de réalisation de l'invention, une substance liquide circule à travers une conduite d'aspiration (14) ou un tube d'aspiration dans un séparateur d'air (16) et du séparateur d'air (16) en avant à travers un dispositif de pompage (23). L'air présent dans la substance liquide est séparé dans le séparateur d'air (16) par le vide, un dispositif de vide (20) étant actionné lorsque la pression régnant dans le séparateur d'air (16) dépasse une valeur prédéterminée. L'écoulement de la substance liquide vers le séparateur d'air (16) est régulé à l'aide d'un dispositif de commande (15) situé dans la conduite d'aspiration (14), ce dispositif de commande étant régulé en fonction du niveau de la substance liquide dans le séparateur d'air (16). Lorsque le niveau de la substance liquide atteint dans le séparateur d'air (16) un niveau inférieur (B) dépendant de l'ordre de grandeur de l'écoulement, le dispositif de commande (15) s'ouvre entièrement, et vice-versa. Lorsque le niveau de la substance liquide monte dans le séparateur d'air (16) entre ledit niveau supérieur (A) et ledit niveau infférieur (B), le dispositif (15) réduit (ou augmente, lorsque le niveau baisse) l'écoulement de la substance liquide pénétrant dans le séparateur d'air (16).
