Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus for operating a gas turbine system are disclosed utilizing an adiabatic combustion process, employing combustion of a pre-mixed carbonaceous fuel-air admixture in a combustion zone.  The combustion and the combustion zone are maintained at an approximately constant temperature by selective control of the fuel-to-air ratio over a period of turbine operation during which the fuel demand or the combustion air temperature varies.  The fuel-air admixture is mixed with combustion products formed in a combustion zone into which the admixture is introduced. The fuel in the admixture is thermally combusted under essentially adiabatic conditions at a temperature approaching the adiabatic flame temperature to sustain the formation of combustion products.  The resulting effluent is characterized by high thermal energy useful for generating power and may be low in atmospheric pollutants, including oxides of nitrogen.

Abstract: Abstract of the Invention An injection molding machine is provided with a pair of opposed mold platens in a horizontal hydraulic press arrangement. The first mold platen is stationary and holds one half of the mold. The other half of  the mold is mounted on a moving platen which rides on a set of ways and is guided by two tie rods. The movable platen is powered by an arrangement of hydraulic cylinders. In the open most position of the platens, the movable platen is transversely adjacent a mold shuttle plate receiver station. A mold shuttle plate is supported on the front face of the movable plate and comprises a portion of the mold. After the injection molding machine has filled a mold, the platens separate to their fullest extent activating control mechanisms which withdraw the mold shuttle plate from the movable platen and transfer it to the receiver station. The receiver station is adjacent the confines of the hot molding area, permitting large, unweidly parts to be easily removed from the mold, and inserts, if any need be installed in the mold prior to the mold plate recycling again in the injection molding machine.

Abstract: ABSTRACT A spray booth installation has a water tank from which water is withdrawn by a pump to feed a water curtain covering a wall located above a dividing baffle plate in the tank and to feed sprays in an air extraction passage disposed above a back region of the tank. A surface-removal device including a venturi pump keeps the water surface clear of paint in the vicinity of the pump inlet and ejects the floating paint on the other side of the baffle plate. A surface baffle in the back region retains floating material while allowing water to circulate back to the front region.

Abstract: APPARATUS FOR REAL TIME TRANSFER OF DATA                  Abstract of the Disclosure There is disclosed an improved interface apparatus and technique for real time transfer of characters from a text processor to a magnetic card recorder.  Characters retrieved from a buffer are subject to reformatting and other operations, the duration of which varies within two character output cycles.  The disclosed technique permits time, in effect, to be borrowed from succeeding character cycles.  A character is processed and loaded temporarily in a register.  The parallel character is then transferred to a serializer register which outputs serial bits to a card writer control for recording on a magnetic card.  At the same time this transfer, seriali-zation, and output is occurring the processor is preparing the next character to be written.  A character can be output in real time so long as the interval between it and the preceding character is less than two character output cycles in length.

Abstract: METHOD OF PRODUCING MATERIAL PATTERN Abstract of the Disclosure The specification discloses a method of producing patterns of a material on a substrate.  In this method, a mask is located over the substrate and both elements are fixed in a substrate holder.  An evaporated film of the desired material is formed on the surface of the substrate by means of an evaporation source provided to confront the substrate through the mask.  The mask is formed with a plurality of reinforcing bridges located in desired portions of the mask openings.  The mask is held spaced from the substrate by a small distance during the evapora-tion, so that the evaporation may be effected through at least two pattern openings defined on opposite sides of each bridge.  The evaporation is performed by means of evaporation sources which are located such that a line interconnecting one of the edges of each bridge and an evaporation source located on the open side of said edge and another line interconnecting the other edge of the bridge and an evaporation source located on the open side of said other edge intersect each other at a point on the surface of the substrate or in the clearance between the substrate surface and the mask.  This method makes it possible to produce patterns of complex shape which could not be produced by the conventional evaporation method.

Abstract: CARRIER CONCENTRATION CONTROLLED SURFACE ACOUSTIC WAVE VARIABLE DELAY DEVICES                           ABSTRACT An electrically controlled surface acoustic wave (SAW) delay unit includes a piezoelectric and semiconductive sub-strate having a segmented rectifying contact disposed on the surface of an interaction region between launching and de-tecting transducers, with a controllable voltage applied to the rectifying contact, thereby to vary the concentration of carriers in the semiconductive material, so as to commensurately alter the velocity of surface acoustic waves in the module. The segmented contact provides significant increase in the achievable variation in velocity, and therefore in phase as well.  An oscillator configuration includes such a module with an amplifier and other circuit elements formed integrally there-with in a monolithic fashion.  Exemplary embodiments include depleting the carrier concentration of semiconductive material, both piezoelectric material and nonpiezoelectric material having a piezoelectric surface layer thereon, as well as enhancement of carrier concentration of semiconductive material at the interface with a piezoelectric surface layer thereon.

Abstract: DUAL MODULUS PROGRAMMABLE COUNTER              ABSTRACT OF THE DISCLOSURE    The inventive counter is operable to divide an input signal by the sum of two binary numbers, A and B.  Each number is stored in memory.  These numbers are alternately preset into a binary counter which also receives the input signal.  A logic gate monitors the counter output and changes state when the number previously preset in the counter equals the accumulated count.  The gate state transition is used to preset the counter with the alternate stored number. Thus, the process continues whereby the output from the logic gate represents the input signal divided by the sum of A and B.
