Abstract: Title: Apparatus for preparing hot drinks.                       Abstract Apparatus for brewing, in particular, a multiplicity of consumption units of a hot drink, such as coffee. The apparatus comprises a combination of a filter pan and a disposable filter cartridge with cellulose web filter. According to the invention, the filter cartridge and the filter pan have parts cooperating to provide a circumferential seal, dimensioned so that when introduced the filter cartridge rests loosely in the filter pan without being clamped therein, and a seal is provided by means of capillary forces that occur during brewing in the gap between the cooperating parts.      The filter cartridge may have an axially symmetrical body, and the parts of the filter pan and the filter cartridge co-operating to provide a seal may have a substantially equal axially symmetrical conicity.

Abstract: METHOD AND APPARATUS FOR CONSTRUCTING REINFORCED CONCRETE WALLS IN THE EARTH                ABSTRACT OF THE DISCLOSURE        Reinforced concrete walls, particularly circular shafts are constructed in difficult and rocky ground by casting a pair of guide walls spaced apart a distance larger than the nominal thickness of the final wall structure and the trench excavation for the wall is carried out between the two guide walls.  Initially, backfilling is of a plastic erodable mix-ture such as cement-bentonite, sand-cemente-bentonite, which have no large aggregates.  At the surface above the guide walls, forms are set for casting the reinforced structures which are to form the concrete wall per se and hollow pipes are embedded in the structure at spaced intervals, each with pipe couplings extending out of the concrete, along with the vertical runs of the steel reinforcing bars, for the next succeeding section.  Water is then injected into the pipes gradually washing the erodable backfill material and facili-tating the descent of the cast concrete section, which is lowered by jacks anchored to the guide walls.  The material of the backfill is washed out of alternate pipes (water is injected in one ,soil and water exits from the next pipe). As the wall section is lowered, the next concrete wall-section is formed and concreted in sequence.  As each wall section is formed, the next pipe section is coupled to the protruding sections and the next reinforcing elements are secured to the protruding reinforcing bars of the element that has been lowered.  The sequence continues until the whole structure has reached the design depth, or a bearing stratum or rock. Finally, as the structure reaches the design depth, the pipes can be used as grout pipes to extend a drill curtain below the bottom, fill the contact between the structure and the rock and grout any voids left around the structure by washing of the backfill.

Abstract: ABSTRACT OF THE DISCLOSURE A pulsed coolant thermocouple temperature measur-ing  system  is  arranged to measure  temperature above a limit operating temperature of the thermocouple includes a rake which is disposed across a hot gas path combustion turbine.          Multiple thermocouple are disposed in respective channels in the rake to sense the temperature of hot gas from surplus which enter the thermocouple channels through respective  sampling ports in the rake.  The sample gas flows merge with a common channel and exhaust through a hot gas sample valve.          When any of the thermocouples reaches a limit temperature,  a coolant valve is opened as the hot gas valve is closed so as to drive coolant air into the common channel  over the  thermocouple  through  the  thermocouple channels and the sampling ports into the hot gas path.          A microcomputer receives and records the thermo-couple signals and generates control signals to sequence the coolant and gas sample valves on and off as a function of the thermocouple temperature signals so the system is cycled  through  successive  temperature  reading  periods without exceeding a predetermined temperature limit of the thermocouples.          The microcomputer  extrapolates  the actual gas temperature as the endpoint temperature computed by a fast integrating   method   from   the   recorded  thermocouple readings.

Abstract: OIL RECOVERY PROCESS     ABSTRACT OF THE DISCLOSURE      A process for recovering oil from an oil-bearing subterranean reservoir penetrated by at least one injection well and at least one production well which comprises the steps of:         (1)  injecting into the oil-bearing subter-ranean reservoir through the injection well a first injecting fluid consisting essentially of (a) 1% to 30% by weight of an internal olefin sulfonate having 10 to 26 carbon atoms and a disulfonate content of 20% by weight or less, (b) 0.1% to 20% by weight of a cosur-factant, and (c) a brine;         (2)  injecting, as a second injecting fluid, an aqueous polymer solution having a viscosity higher than that of the first injecting fluid into the oil-bearing subterranean reservoir; and (3)  recovering oil replaced with the first and second injecting fluids through the production well.    This process can recover oil from subterranean reservoirs at a high oil recovery efficiency without destroying a micro-emulsion during sweeping in the subterranean reservoir even when the salt concentration of the formation water is widely changed.

Abstract: ABSTRACT      A power switching circuit for switching power repetitively to a load at a relatively low frequency employs a power switching device which is driven across an isolating transformer interface.  The drive signals are high frequency pulse signals which are modulated with the low frequency switching information, the modulations being detected in the secondary circuit of the transformer.  Such an arrangement affords isolated driving with fast switching edges and requires only a small transformer.  Power for the detection circuit is derived by rectification of the high frequency signals induced in the transformer secondary.

Abstract: ABSTRACT         A fast, low power integrated circuit logic is provided which is particularly suited for integration with high electron mobility substrates such as gallium arsenide (GaAs) or indium phosphide (InP).  A forward biased Schottky diode serves as the nonlinear logic element and is used to switch a field effect transistor (FET).          The FET is preferably a depletion mode metal-semiconductor field effect transistor (MESFET). A reverse biased Schottky diode is connected in parallel with the forward biased Schottky diode to improve circuit performance, and in particular, switching speed.  Alternatively, if the switching speed is held constant, the present invention dissipates less power than similar logic circuits which do not employ the reverse biased Schottky diode.
