A procedure and a device that is utilised to localise insulation faults between several alternative linked cables and sheath (2') or screen in a metal-sheathed or screened cable. A signal source (4) is placed so that it can be connected between each defective cable and the sheath or screen at the one end of the cable so that it gives rise to a signal current through the sheath or screen respective...

In a device for providing a direct indication of an error position (R') on a metal-sheathed cable (1'), we utilise a signal assembly that can be connected to the one end of the cable (1a') an initial terminal (5a') being connected to the cable sheath and a second terminal (5b') to a defective cable (3'). When the assembly is activated, a signal current will flow through the metal sheath, the error...

By a method of reproducibly testing the resistance to wear and change in appearance as well as the soil resistance of construction units (4) in full size within the furniture field with associated environments, the construction unit (4) or parts thereof in its full construction is positioned secured on the inner side of a rotatable large drum (1) and subjected to stresses from various stress membe...

The drum for a cable has a contact fitment at each end, and comprises a primary core (1) with a gable (2) at one end, and two other gables (3,4) at its other end. The latter two gables are separated by a secondary core (5) on which the cable inner end is accomodated. The remainder of the cable is wound on to the primary core. The exterior of one of the latter two gables (4) has a space (6) which c...

The keyboard keys have electrical contacts, being arranged in rows on a base. The base has a right (15) and a left (14) half, with holders (18-20). By virtue of the holders, the base halves can be moved from a position where the keyboard rows in the two halves form straight lines, to one where they form broken lines. This provides a facility for adjustment to suit the direction of the arms of a us...

In the plasma spray deposition of an abrasive grit coating on a substrate, abrasive grit particles are injected into a high temp. plasma stream at a location downstream of the location at which matrix material particles are injected, in a direction 180 deg. apart at the plasma stream circumference from the direction of matrix particle injection and at a distance from the substrate such that the ma...

The combustion control device comprises a fuel container (3) with a bottom outlet through which solid fuel is fed to a primary combustion chamber (4) for burning with air deficiency. A fan (6) partly blows in primary air into the primary combustion chamber, and partly blows secondary air into a secondary combustion chamber. - In the secondary chamber, secondary combustion of gases coming from the ...

The adjustable door hinge has first (2) and second (1) fixed parts for respective fitment on a door frame and panel. The fixed parts are pivotable relative to each other around a pin (11) accommodated in a hole. The pin is eccentrically fitted on an adjustment body. A fixture pin (10) is pivotable around an axis parallel to the hinge pivot axis, and is movable in a height direction by an adjustmen...

The post removal device has an upper (9) and a lower (10) ring-shaped component, of which at least the upper component comprises two circular parts. At one end the circular parts are joined to each other by hinges. At their other end the ring-shaped component parts are provided with a lock unit which holds them together in a circular shape. The upper component has radial tensioners (23,24) acting ...

1. Tap changing switch of the load selector type with a plurality of stationary contacts (K1, K2, K3) which are arranged on a path (1), are electrically insulated from one another, and are intended for being connected to the taps of the regulating transformer, with a movable contact carrier (2) carrying one main contact (H) and two auxiliary contacts (M1, M2) located on one side each of the main c...
