Abstract: ABSTRACT OF THE DISCLOSURE          An electro-osmotic method for the production of hydrocarbons utilizes in situ heating of earth formations having substantial electrical conductivity. A particular volume of an earth formation is bounded with a waveguide structure formed of respective rows of discrete elongated electrodes in a dense array wherein the active electrode area and the row separation are chosen in reference to the deposit thickness to avoid heating barren layers.  Electrical power is applied at no more than a relatively low frequency between respective rows of electrodes to deliver power to the formation while producing relatively uniform heating thereof and limiting the relative loss of heat to adjacent regions to less than a predetermined amount. At the same time the temperature of the electrodes is controlled near the vaporization point of water to maintain an electrically conductive path between the electrodes and the formation.  A heat sink is provided by supplying aqueous liquid electrolyte to space between the electrodes and the adjacent formation, thereby maintaining the temperature thereat no greater than about the boiling point of water and maintaining a conductive path between said formation.  A d.c. polarized potential is applied to enhance flow of reservoir fluid into a preselected row of electrodes, and collected reservoir fluids are removed from the electrodes in the preselected row.

Abstract: TEST DEVICE FOR AN OPTICAL INFRA RED DETECTOR           ABSTRACT      A test device for a multiple channel infra red detector utilizing photocells comprising an aperture plate mounted on the housing member of the detector.  In the embodiment described a test lamp is mounted on a surface portion of the aperture plate in fixed relationship with two openings in the plate which are concentrically disposed about the two photocells.  The system utilizes the characteristic of the dual channel detector that the ratio of the response of each of the two cells to emissions in the infra red range (as received from a fire) is a certain value.  The opening associated with one of the cells is larger in the path between the lamp and that cell so that more light energy impinges on it.  The electrical energy to the lamp is increased until a level is reached where the ratio of the response of the one cell to the response of the other cell simulates the responses of the two when monitoring a fire.  The warning system is triggered.  A numerical value can be determined which is indicative of the sensitivity of the detector and which is repeatable.

Abstract: Abstract A process is disclosed for the purification of a gaseous stream contaminated at least with CO2 and H2S.  The gaseous stream is preheated and subjected, in the presence of recycled SO2, to a catalytic conversion of H2S into elemental sulfur.  The thus-obtained sulfur is separated, and the residual gas, which contains at least H2S, SO2, CO2, and water, is freed absorptively from SO2 after oxidative conversion of H2S to SO2. It is proposed that the residual gas, after oxidative conversion of H2S to SO2, is cooled in heat exchangers, preferably regenerators, and is subsequently scrubbed with a solvent consisting predominantly of tetraethylene glycol dimethyl ether.

Abstract: ABSTRACT        A reserve tank is built into the vehicle, and communicates with a filler pipe.  A sleeve extends into the reserve tank, the upper end of which defines the reserve capacity, and the other end of which is connected with the inlet of the fuel tank.  The contents of the reserve tank can be transferred readily into the fuel tank via a bypass with a valve. An expansion tank with a volume of at least 10% of the fuel tank volume, is likewise connected with the fuel tank via a pipe.  An air vent connection of the fuel tank and an air vent connection of the expansion tank are alternately connected with the atmosphere via valves controlled by a closure device, in such a way that, when the filler is open, the air vent connection of the fuel tank is opened, while the air vent connection for the expansion tank is shut.  A non-return valve is incorporated in the passage which leads from the connection on the fuel tank via the expansion tank into the air vent connection for the expansion tank.

Abstract: Abstract of the Disclosure:         In a radio communication system comprising a fixed unit (10) carrying out a first scanning operation at a channel scanning period in a waiting state and a portable unit (11) intermittently put in a waiting state thereof into active and inactive for active and inactive durations, respectively, the portable unit comprises a power source circuit (30) for rendering a sum of the active and the inactive durations equal to the channel scanning period.  In each active state, a frequency synthesizer (39) carries out a second scanning operation to successively scan the radio channels one by one in cooperation with the controller (38) to detect whether or not each of the radio channels is idle.          The second scanning operation may proceeds either in the same order as the first scanning operation or in a reverse order relative to the first scanning operation.          Alternatively, the second scanning operation may be carried out in a phase different from the first scanning operation.  In this event, either one of the fixed and the portable units that is delayed in phase may skip from an actual channel to an additional one.

Abstract: ABSTRACT         The purpose of the Wicks efficient Fuel Utilization System (WEFUS) is to produce electric energy and head simultaneously in a fuel conserving and cost effective manner.  WEFUS is a new and novel system that combines the fuel conserving technique of cogeneration with the fuel conserving technique of condensing heating so that the resulting combined system has an additional fuel conservation benefit relative to a system that uses only one of these fuel conserving techniques.       The internal components are all conventional and in-clude an internal combustion engine (15), an electric induction machine (17), a fan (18), a high temperature heat exchanger (20), a low temperature condensing heat exchanger (21), along with a controller (14), that controls the position of a solenoid controlled fuel valve (11) and a solenoid controlled electric breaker (13) in response to a signal from a thermostat (27) and conditional to signals from an electric power sensor (25) and unsafe condition sensors.       WEFUS also has some inherent safety advantage rela-tive to conventional furnaces since there is no large combustion chamber and additional safety advantages result from conditions that are sensed and input to the controller which then isolates the system from the fuel and electric power connections if an unsafe condition is sensed.
