Abstract: Abstract Of The Disclosure A small diameter fluid-driven pump for subterranean fluid sampling, and including an elongated cylindrical body formed by a centrally disposed control valve block assembly and a pair of hollow motor piston chambers on opposite sides of the valve block and joined thereto.  Interconnected motor pistons are reciprocably disposed in the motor piston chambers, and each is connected to a pump piston.  Each pump piston works within an axial bore in a tubular pump housing.  The pump housings are secured to the opposite ends of the cylindrical body.  A pump valve assembly is secured to the end of each pump housing, and each includes intake and discharge valves.  Within the centrally disposed control valve block assembly in axial alignment with the motor pistons are a spool pilot valve and a spool fluid distribution valve.          The spool pilot valve is constructed to obviate stalling during its reciprocation under the impress of a power fluid directed thereto, and it functions to control the shifting of the distribution valve to which it is internally connected within the valve block assembly.  The distribution valve functions to alternately charge one motor piston chamber while receiving power fluid discharged from the other, then shifts, upon direction from the spool pilot valve, to charge the other motor piston chamber and receive exhausted power fluid from the one previously charged.

Abstract: Abstract of the Disclosure A low noise frequency converter particularly adapted for the large bandwidth environment encountered in extended bandwidth cable television (CATV) systems is disclosed.  The CATV converter includes an upconverter/ downconverter combination for translating the received RF signal to an intermediate frequency (IF) carrier signal.          A first IF signal is generated by heterodyning the received RF signal with the output of a voltage controlled oscillator in a first double balanced mixer.  The upconverted signal thus produced is then mixed in a second double balanced mixer with the reference output of a second local oscillator to provide a fixed, downconverted second IF carrier signal.          The upconverter portion of the CATV converter includes a pin diode attenuator between an RF amplifier and the first double balanced mixer.  The pin diode attenuator is driven by the RF amplifier and is regulated by the signal receiver's automatic gain control (AGC) system permitting signal level to be increased at a faster rate than noise figure resulting in an improved converter signal-to-noise ratio and improved large signal handling capability.  The downconverter portion of the CATV converter includes a double balanced diode mixer between the first IF amplifier and the second IF amplifier.  With the double balanced diode mixer for the second mixer in the downconverter section, cross-modulation and intermodulation distortion from adjacent channels is reduced.  In addition, the double balanced diode mixer provides an improved overall noise figure due to its lower noise performance than that available with either a single ended diode mixer or active mixer.

Abstract: A B S T R A C T     A coupler for light between the termination of an optical fiber and one or more detector or emitter elements in which the optical path between the termination and the detectors and emitters includes one or more focussing surfaces. The coupler is designed as a molded plastic body adapted to precisely position the optical fiber termination and the emitters and detectors so that the optical path between them via the focussing surfaces couples light efficiently. The focussing surfaces are molded into the coupler during manufacture and are preferably angled to the radiation to provide total internal reflection, avoiding reflective coatings. In the case where the focussing surfaces are reflecting, they are preferably ellipsoidal or paraboloidal in shape. In a second case, one surface is beam splitting and a second surface provides focussed reflection. In another case one focussing surface is reflecting while a second focussing surface is refracting. The coupler permits the realization of various features including precise alignment between the fiber, emitters and detectors; physically separated surfaces; cross-talk elimination; insensitivity to variations in radiation wavelength, index of refraction and dimensions of the coupler; aberration correction; ease of molding without side actions in the mold; and design flexibility in the placement of the focussing surfaces.

Abstract: DATA PROCESSOR HAVING MULTIPLE BUS CYCLE OPERAND CYCLES       Abstract of the Disclosure In a data processor adapted to perform operations upon operands of a given size, a bus controller is provided to communicate the operands with a storage device having a data port which may be a submultiple of the operand size.  In response to a signal from the bus controller requesting the transfer of an operand of a particular size, the storage device provides a size signal indicating the size of the data port available to accommodate the requested transfer. Depending upon the size of the operand to be transferred and the size of the data port of the storage device, the bus controller may break the operand transfer cycle into several bus cycles in order to completely transfer the operand.  In the process, the bus controller compensates for any address misalignment between the operand and the data port.  In order to distinguish individual operand cycles from the several bus cycles which may comprise the operand cycle, the bus controller provides an operand cycle start signal only at the start of the first bus cycle of each operand cycle.
