Abstract: ABSTRACT OF THE DISCLOSURE             A two-way electronic kWh meter is disclosed for metering electrical power and energy consumption in a single or polyphase electrical system wherein power and energy may be imported to the system or exposed from the system to another system.  Pairs of analog signals representing current and voltage variables are derived. Each pair of analog signals is multiplied together to derive partial instantaneous power signals.  These signals are summed and integrated to thereby provide a signal which is proportional to the total energy being imported or exported with respect to the electrical system.  Depending upon the polarity of the signal being detected, an import or export record and display arrangement is connected to receive the pulse train to record the quantity of energy being imported or exported with respect to the system.

Abstract: PROCESS FOR THE SUSPENSION SMELTING OF SULFIDE CONCENTRATES               ABSTRACT OF THE DISCLOSURE A process for the suspension smelting of sulfide concentrates by causing a suspension flowing downwards in a suspension reaction zone to impinge against the surface of a melt below the suspension reaction zone in order to unload the solid and molten particles of the suspension into the melt and by causing the gases to flow further in the suspension reaction zone countercurrently in relation to the suspension in order to discharge the gases from the upper section of the suspension reaction zone, in which sulfide concentrate and oxygen or oxygen-enriched air are fed into the suspension reaction zone symmetri-cally and in the form of so dense a suspension spray that the iron oxide of the high-temperature suspension is in a molten state and absorbs the free oxygen present in the suspension before the suspension, at a temperature of at least 1400°C, unloads into the melt, the heat is recovered indirectly in the suspension reaction zone from the gases rising symmetrically and smoothly around the suspension, and the melt is fed from the suspension reaction zone into a separate melt reaction space.

Abstract: ABSTRACT OF THE DISCLOSURE           A presence sensor for safeguarding a machine has a plurality of light sources and opposed light detectors provi-ding a protective curtain in front of an area to be protected.      The photodetectors are connected to respective gates which are enabled in sequence as the corresponding light sources are energized in sequence.  Each light path that is obstructed causes a pulse from the gates and these pulses are totalled for each sequence to provide a total count output.  A compar-ator compares the total count output to a predetermined number representing a permissible number of obstructed light paths.          If the total count output exceeds the predetermined number the comparator provides a signal which stops the machine.  The predetermined number is set at a low number which is sufficient to permit material to be fed into the machine through the protective curtain  but which is not sufficient to permit the operator to reach the dangerous operating area.  In the prior art it is possible to set the safeguard to permit certain light paths to be obstructed and no others.  Thus  a change in the angle of feed as the material extends through the curtain could stop the machine unnecessarily.  The presence sensor of this invention permits the obstructed light paths to be anywhere as long as the number obstructed does not exceed the predetermined number  so that the angle of feed can be changed from horizontal if this is necessary  or the material can be bent in the machine causing a projecting part to alter its position in the curtain  stopping the machine.  Different die heights can be used in the machine without altering the set-up of the guard curtain.

Abstract: ABSTRACT OF THE DISCLOSURE                     IMPROVEMENTS IN OR RELATING TO MEDICAL RADIOGRAPHIC APPARATUS           In a computer-assisted tomography (CAT) apparatus, in which a fan-shaped X-ray distribution (2) is rotated about the patients body (4), it is possible to use a ring of stationary detectors (7) disposed to received the radiation after passage through the body.   In this arrangement the ring of detectors is of smaller radius than the locus of motion (5) of the radiation source (1).   It would appear that this would cause the detectors to obscure the body from the radiation.   An arrangement disclosed moves out of the radiation beam thos detectors which would present an obstruction so that only those required to collect radiation lie in the beam.

Abstract: "ARRANGEMENT FOR CONCENTRATING SEA WAVES"     Abstract of the Disclosure Arrangement for concentrating sea waves, com-prising a grid-like structure of stopping and/or delaying elements adapted to influence the amplitude and/or phase of the waves and located in such positions in the water that the ele-ments in interaction with the incident sea waves form an inter-ference pattern which gives a concentration of the wave energy in a limited area (concentration area).  When the wave energy is to be utilized for power production, the grid-like element structure is designed to give a concentration of the wave energy in a concentration area being located in the short-range field of the element structure.  Preferably the elements in the structure are mainly situated in front of the concen-tration area with respect to the dominant wave incident di-rections.  Moreover, the element structure may have an exten-sion (aperture) which is substantially larger than the wave length of the dominant waves at the location.
