Abstract: A method of remotely determining an impedance of an earth connection (142) of a first electrical equipment (122) connected to a power supply network (300). The method comprises receiving (606), from a first measurement node (302) connected to the first electrical equipment, a first value of an insulation impedance of the power supply network and receiving (612), from a second measurement node (304) connected to the power supply network, a second value of an insulation impedance of the power supply network. The method further comprises calculating (614) the impedance of the earth connection of the first electrical equipment using the first value of the insulation impedance of the power supply network, the second value of the insulation impedance of the power supply network and a known impedance value of an earth connection (144) of the second measurement node.

Abstract: Systems, methods, and processor-readable storage media for processing merchandise shipping are provided to ensure that a supplier fulfills a purchase order in a manner that will keep a supply chain filled with the product based on a demand. For example, when a purchase order is generated, a timer can be activated. Within a predetermined period, the supplier can confirm fulfilment of purchase order through an online platform. Based on this confirmation and historical data collected for the supplier, a shipping location and other shipping parameters can be predicted by the online platform. If the timer is expired and no supplier's confirmation is received or if the supplier denies confirming the fulfilment of purchase order, a default operation is initiated. The default operation may cause canceling of purchase order or communicating to the supplier to resolve any issues.

Abstract: An armrest for a chair is provided which has an improved anti-rotation and mechanical connection between an armrest body and a frame tube of the chair. The end of the frame tube is mechanically deformed or is shaped so as to have a non-circular profile with a central opening defined by inwardly projecting arcuate surfaces of the frame tube. The armrest includes a cooperating, non-circular socket which fits onto the frame tube wherein a suitable fastener is threaded downwardly into direct, self-threading engagement with an upper opening formed in the end of the frame tube.

Abstract: A separator system has a plurality of separator stages (11, 12, 13) and operates to remove particulates from air, particularly in the inlet to an engine. Each stage includes a plurality of side-by-side inertial separators (26) through which the air flows and by which particulates are removed. Each stage (11, 12, 13) produces a pressure drop and the additional total pressure drop produced by each stage after the first is less than the additional total pressure drop produced by the preceding stage in an upstream direction. This allows particulates to be removed by the separator stages (11, 12, 13) alone without the use, in normal operation, of a barrier filter (14).

Abstract: A clasp for releasably grasping a snap hook to aid attachment of said hook to a remote eyelet, the clasp adapted to be mounted on a pole and comprising a flexible, curved and grooved member shaped to receive and partially and releasably encircle the outer surface of a snap hook such that the hook opening faces away from the pole.

Abstract: A tilt control mechanism for an office chair includes a spring arrangement which permits forward and rearward tilting of the chair while also urging the chair to a normal upright position. The spring arrangement includes front and rear springs which act in combination such that the upward acting forces acting on the chair can be varied during use. The forces being applied by the front spring are adjusted by a side-actuated tension adjustment mechanism which incorporates a wedge block for adjusting the spring forces. Further, the rear springs provide a variable spring force such that the spring force is maximized when in the normal position but is decreased substantially once the chair is fully reclined. This reduction in spring force allows a user to maintain the chair in the fully reclined position with significantly less force than was required to tilt the chair rearwardly while a sufficient spring force continues to be applied by the front spring to urge the chair to the normal position.
