Abstract: Apparatus for removing milk from a teat of an animal comprising an outer body having an opening into which the teat is insertable into a space defined by two or more resilient membranes. A pressure difference is applied between the space between the resilient membranes and a region outside the membranes to cause the membranes to ball on to the teat, thereby massaging it to extract milk. To avoid exerting excessive force on the end of the teat yet retain a useful massage pressure, the resilient membranes are under tension in a direction transverse to the direction of teat insertion before the provision of any pressure difference (before the insertion of the teat).

Abstract: Aspects of the invention relates to a system and method for determining the efficacy of the catalyst comprising means to detect any temperature change in the catalyst when oxygen is present in the anaerobic workstation and determine the efficacy of the catalyst in accordance with the temperature change. A detectable rise in the temperature of the catalyst is indicative of a catalytic reaction to remove oxygen from the anaerobic work station. Thus, the system determines the catalyst is an active catalyst if the temperature of the catalyst rises when oxygen is present in the anaerobic workstation. The system determines the catalyst is an inactive catalyst if the temperature of the catalyst does not rise when oxygen is present in the anaerobic workstation. Further aspect of the invention relate to a system and method for determining the atmosphere of an anaerobic workstation in accordance with the efficacy of the catalyst of the anaerobic workstation.

Abstract translation: 本发明的方面涉及用于确定催化剂功效的系统和方法，其包括在氧存在于厌氧工作站中时检测催化剂中任何温度变化的手段，并根据温度变化确定催化剂的功效。 催化剂温度的可检测的升高表明从厌氧工作站除去氧的催化反应。 因此，如果在厌氧工作站中存在氧气时催化剂的温度上升，则系统确定催化剂是活性催化剂。 如果在厌氧工作站中存在氧气时催化剂的温度不升高，则系统确定催化剂是惰性催化剂。 本发明的另一方面涉及根据厌氧工作站的催化剂的功效确定厌氧工作站的气氛的系统和方法。

Abstract: The invention relates to apparatus for milking animals such as cows, components of the apparatus and methods of milking animals employing the apparatus. The apparatus comprises at least two resilient membranes having a space therebetween into which the teat of the animal may be inserted. The membranes are held by a support structure under tension in a direction transverse to the direction of insertion of the teat, to protect the teat from excessive force when the membranes fall onto the teat.

Abstract: The present invention relates to a liquid barrier assembly (1) comprising at least two barriers (2,3) each comprising a substantially rigid container and a front wall (5) against which liquid is intended to be incident. Adjacent barriers (2,3) are linked by a connector (12) which comprises a first relatively rigid portion (13) and a second relatively deformable portion (15). The portions (13, 15) are received in respective recesses defined in neighbouring side walls of adjacent barriers (2,3). The second portion (15) is deformed upon juxtaposition of adjacent barriers (2,3) in a predetermined manner so as to form an effective water-tight seal between the barriers (2,3).

Abstract: The present invention relates to a liquid barrier assembly (1) for the prevention of flow of liquid from one area to an adjacent area. The assembly (1) comprises at least two barriers (2,3) each comprising a substantially rigid container and a front wall (5) against which, in use, liquid is intended to be incident. Adjacent barriers (2,3) are linked by a connector (12) which comprises a first relatively rigid portion (13) and a second relatively deformable portion (15). The portions (13, 15) are received in respective recesses defined in neighbouring side walls of adjacent barriers (2,3). The second portion (15) is deformed upon juxtaposition of adjacent barriers (2,3) in a predetermined manner so as to form an effective water-tight seal between the barriers (2,3). The arrangement is particularly suitable for flood defence barriers.

Abstract: A modulated bias unit is provided for controlling the direction of drilling of a rotary drill bit when drilling boreholes in subsurface formations. The unit comprises a plurality of hydraulic actuators spaced apart around the periphery of the unit and having movable thrust members hydraulically displaceable outwardly for engagement with the formation of the borehole being drilled. Each actuator has an inlet passage for connection to a source of drilling fluid under pressure and an outlet passage for communication with the annulus. A selector control valve connects the inlet passages in succession to the source of fluid under pressure, as the unit rotates, and a choke is provided to create a pressure drop between the source of fluid under pressure and the selector valve. A further choke is provided in the outlet passage from each actuator unit. The actuators and control valve arrangements may take a number of different forms.
