摘要： A system and a method for maintaining operation of a signaling interconnection between a first ring network and a separate second ring network. Each ring network comprises two communication paths transmitting data in opposite directions and at least two nodes connected to both communication paths. The networks are interconnected via two adjacent gateways, which receive data from the two communication paths on one network, and transmit the data onto the other network directed away from the other gateway. Data traffic is stopped in both directions in an inactive segment on each ring network, so that a node situated on a ring network receives traffic from only one of the two gateways.

摘要： An active booster transformer system with a booster transformer core (S, 10, 17) of the type which is applied around an electrical cable (K, 1, 13) for reducing stray currents and in which the booster transformer core is a body built up of a magnetizable material provided with a continuous channel intended to accommodate the cable. The system includes a current sensor (G, 2-3, 14-15) which senses the net current in the cable (K, 1, 13), an amplifier unit (F, 4-7), the input signal of which is controlled by the current (Iv) sensed by the current sensor, and a magnetizing winding (L, 3, 15) situated on the booster transformer core (S, 10, 17). The output of the amplifier unit is arranged to drive the magnetizing winding and to create a magnetic flow in the booster transformer core, the flow, in turn, inducing a longitudinal voltage in the cable which counteracts the stray current.

摘要： In an ice-breaking ship, having sufficient power and being generally designed for efficient ice-breaking, the breaking of the ice is made more effective by changing the zone of ice crushing and shearing which occurs at the stem during normal ice-breaking of level ice, to a zone where the breaking occurs due to bending. This is obtained by forming the front portion of the ship so that at least within the area where the stem contacts and breaks level ice, the basically wedge-formed stem is truncated to form a relatively broad runner-like portion being inclined forwards in a relatively small angle to the water line plane of the ship. The width of the runner-like portion is determined in conformity with the general ice-breaking ability of the ship, whereby the driving power (P) of the ship, in kW, and the maximum beam (B) of the ship at its design water line, in meters, forms the basis for calculating, in meters, the width (W) of the runner-like portion by means of the formula:W=(0.02 to 0.08)(P/B).sup.0.63. spThis application is a continuation-in-part of co-pending application Ser. No. 826,674 filed Aug. 22, 1977, which is a continuation of application Ser. No. 594,491 filed July 9, 1975, both now abandoned.

摘要： In a spark gap device a number of arc-resistant insulating elements are stacked in spaced relationship to form spaces between adjacent insulating elements with each element having a through-hole. At least two metallic electrodes are sandwiched between the respective surfaces of adjacent insulating elements in spaced relation to form a spark-over gap therebetween. Each electrode includes a recessed portion and the recessed portions of aligned electrodes on respective opposite sides of an insulating element extend through each of the through-holes in contacting relationship. The insulating elements each include at least one elevation which projects snugly into the recessed portion of an associated electrode.
