Abstract: ABSTRACT            The present invention relates to an assembly and a method for feeding electrodes which are used in electrothermic smelting furnaces. The electrode comprises an electrode casing having vertical ribs pro-jecting radially outwards from the casing. A plurality of electrode feeding units, each including a clamping means are arranged around the periphery of the electrode and each clamping means exerts a releasable pressure on a rib, the clamping means imposing only tangentially for-ces on to the electrode. When feeding the electrode, the pressure on one of the clamping means is temporary released and the clamping means is moved in vertical direction relative to the electrode, whereafter the pressure on the clamping means is reactivated. This is done for every electrode feeding unit with a preset time-delay between the movements. When all the electrode feeding units have been moved one at a time, all the electrode feeding units are moved together in vertical direction. The clamping means are formed of two substantially iden-tical reversed parts which are hinged around a central member.

Abstract: ABSTRACT     A padlock, which comprises a lock casing and a basically U-formed  shackle  slideable  therein between a  closed  and  an open position. The shackle has two legs of different length, of which at least one is provided with a locking notch. The padlock also comprises a cylinder lock mechanism,  operable by a key, and at least one locking member coacting with a guiding portion of a turnable member of the cylinder lock mechanism for locking the shackle to the lock casing.  The locking member is movable dependent on the angular position of  the  guiding  portion  of  the  cylinder  lock  mechanism between a locking and a releasing position.  The releasing position allows the shorter shackle leg to completely slide out from the lock casing. A retaining member is attached to the lock casing in order to keep the cylinder lock mechanism properly fitted  in the lock casing.  The removement of the retaining member from the lock casing requires turning of the  retaining  member  in  relation  to  the  lock  casing.  A blocking member is dimensioned in its blocking position to be partly received in a recess in the retaining member and partly in an opening in the lock casing. Thereby it prevents the turning of the retaining member in relation to the lock casing. The blocking member is removable from its blocking position when the shackle is in its open position.

Abstract: "THERMAL MASS FLOWMETERING"    ABSTRACT          Metering and related control of fluid flow are achieved both accurately and at high response speed by way of a unique sequencing of thermal exchanges with the fluid under closely-regulated and inter-dependent thermal conditions. The flowing fluid is first conditioned by being raised to a temperature above its highest anticipated ambient, preferably by way of a temperature-sensitive electrical heater resistance which is part of an exceptional self-balancing bridge and control-loop network, and the conditioned fluid is then similarly increased to yet higher temperature, with measurements related to energy involved in producing the second temperature increase being used to characterize the flow. When the fluid is at the same time further conditioned immediately downstream by another similar heating arrangement which allows the fluid to cool to between temperatures developed by the earlier sequencing, the measurements are rendered more stable and can advantageously be made more linearly proportional to mass flow rate. Addi-tional isolation from ambient temperature disturbances is promoted by controlling the environment within which the sequencing of thermal exchanges take place, preferably by way of a heated enclosure in which electrical regulation of temperature is also swift and exact.

Abstract: ROTARY FLUID PRESSURE DEVICE               Abstract of Disclosure A rotary fluid pressure device is described as comprising a housing having fluid inlet and outlet openings and in the housing is a gerotor device having an external stator having internal teeth and a rotor within the stator having external teeth, one less in number than those on the stator.  The rotor is eccentrically mounted with respect to the stator so that upon rotation of the rotor, the sealing engagement between the external and internal teeth forms expanding cells on one side of the line of eccentricity and forms contracting cells on the other side of the line.  A drive shaft concentric with the rotor has a hollow end within the housing and a solid drive end outside of the housing.  A wobble stick drivingly connects the rotor and the shaft and the wobble stick has a pivot point at its inner end connected by a rigid pivot pin with a central recess in the housing axially of the shaft which eliminates axial movement between the drive shaft and the rotor which would otherwise be caused by an uneven end formed by wear on the wobble stick.  A manifold, fixed in the housing, provides a double balance pad diametrically opposite each of an inlet passage for conducting inlet fluid to each of the cells between the stator and rotor.  Twelve shallow slots are hobbed over six angled holes conducting fluid to the ex-panding and contracting cells and over six radial holes lead-ing to the balance pads, giving the required accuracy.  A novel seal and thrust bearing structure, where the drive shaft exits from the housing, results in good concentricity of the seal carrier and a thrust bearing between the seal carrier and the adjacent end of the housing provides with a flow pumped by the bearing during rotation of the device, which results in a lower temperature on the seal and bearing.
