Abstract: ABSTRACT OF THE DISCLOSURE    An improper or wrong operational mode fault detection and control system for a reverse cycle refrigeration system for detecting faulty operation, i.e., operation in the cooling mode when heating is desired or in the heating mode when cooling is requested, and for controlling the system in response to the detection of a fault by inhibiting the compressor and for providing a fault indication, the control system comprising a controller means receiving inputs indica-tive of the outdoor air temperature, the temperature of the outdoor heat exchanger coil refrigerant, and an output indicative of a demand from a building temperature sensing means for heating or cooling of the building.  The controller means also includes timing means and means for comparing the value of the outdoor heat exchanger coil refrigerant tempera-ture and the value of the outdoor air temperature.  Further, the controller means has an operative connection to control means for controlling the operation of the compressor and functioning to inhibit any further operation of the compres-sor means unless the value of the difference between the temperature of the outdoor heat exchanger refrigerant and the temperature of the outdoor air is less than a first preselected value when the thermostat requests heating, and unless said difference exceeds a second preselected value when the thermostat requests cooling.

Abstract: ABSTRACT OF THE DISCLOSURE           A reaction-jet torquer system carried in a projectile to aim the projectile to a target.  The torquer system uses the thrust of sonic nozzles to control a gyro rotor inertial frame of reference.  The reaction force applied to the gimbal gives the rotor the capability of tracking the target.  A sensor carried by the gyro provides logic which identifies and activates the appropriate nozzle or nozzles of the system to generate the required gimbal force.

Manfred Schmidt Sandgrubenstra.beta.e 19, 7032 Sindelfingen 3. Dr. Peter Biermann K?nzenstra.beta.e 6, 7250 Leonberg 7 ABSTRACT OF DISCLOSURE:     A cross country ski binding for securing a ski shoe by a forwardly directed extension of its sole to a ski features a recess defined between two side walls, a top wall and a base plate with at least one and preferably two bracing members arranged within the recess and extending vertically at right angles to the top wall of the recess. The bracing members are adapted in operation to engage in corresponding longitudinally extending slots in the sole extension and serve to stiffen the recess and to react the tilting moments occurring during skiing. A securing device in the form of a toggle lever mechanism includes a hooked member which serves to engage behind a corresponding projection on the sole extension to draw the same into the binding and to prevent the ski shoe from moving rearwardly out of the binding, Various modifications are disclosed including an embodiment in which the bracing members are formed by inwardly turned portions of the sheet metal base plate of the binding.

Abstract: The invention concerns a process for the recovery of the uranium contained in an impure phosphoric acid. The impure acid is treated with an organic phase capable of extracting U (VI), and the resultant organic phase is then re-extracted with an aqueous solution containing complexing acid and an oxidizing-reducing agent in the reduced state, said oxidizing-reducing agent being capable of reducing U+6 to U+4 in said aqueous solution. The resultant aqueous phase is then subjected to electrochemical oxidation, followed by extraction with a second organic phase from which the uranium is recovered, the depleted aqueous solution being recycled to the re-extraction after electrochemical reduction, with the process comprising two organic phase cycles and a cycle of a complexing aqueous solution. The process is of particular interest when applied to the recovery and concentration of uranium contained in a wet process phosphoric acid.

Abstract: ABSTRACT OF THE DISCLOSURE     This invention relates to modular interconnection systems.  In a well known interconnection technique, a cable is extended from the telephone signalling and switching equipment to a telephone station via a pair of mating connector units.  The present invention provides an improved interconnection system in which the modular concept is provided with added flexibility in the interconnection of telephone signaling and switching equipment and telephone stations.  The present invention provides a telephone connection system for interconnecting circuits of telephone switching and signaling equipment to circuits of a telephone station employs a first multi-conductor cable connected to the switching and signaling equipment and a second cable having a lesser number of conductors connected to the telephone station. Matable connector apparatus connects the conductors of the second cable to selected conductors of the first cable, the connector apparatus including first, second, third and fourth electrical connectors.  The first and second electrical connectors are cooperably matable, and third and fourth electrical connectors are cooperably matable, the third electrical connector being mounted on and covered by a common hood with the second electrical connector. The contacts of the third electrical connector may be connected to selective contacts of a second electrical connector, or such connections may be per-manent and the positions of the contacts of the second electrical connector may be changed in order to provide flexibility in associating the circuits of the telephone station with selected circuits of the switching and signaling equipment.

Abstract: SLM-20.1524 TO ALL WHOM IT MAY CONCERN:           Be it known that I, JAMES H. MORAN, citizen of the United States, residing in the State of Texas, have invented an improvement in INDUCTION LOGGING APPARATUS AND METHOD   of which the following is a SPECIFICATION                 ABSTRACT OF THE DISCLOSURE     An induction well logging apparatus and method is disclosed for determining dip and/or anisotropy parameters of formations surrounding a borehole. A transmitter is provided and includes a first  transmitter coil having an axis which is substantially parallel to the borehole axis and a second transmitter coil having an axis which is sub-stantially perpendicular to the borehole axis.  A receiver is provided and includes first and second receiver coils having axes which are substantially mutually orthogonal. Each of the receiver coils is substantially perpendicular to the borehole axis.  The transmitter and receiver are mounted in a mechanically passive manner on a support member adapted for movement through the borehole.  The transmitter coils are energized in a manner which permits the  separate detection at the receivers of the currents induced in the formations by each of the two transmitter coils. The reactive components of the detected signals are used to obtain dip and/or anisotropy parameters of the formations.  The forma-tion dip angle and/or dip azimuth angle can be determined without dependence on anisotropy. Anisotropy can also be obtained using the described configuration. All advantage of the disclosed technique is that dip angle and dip azimuth angle can be obtained from voltages induced (via the forma-tions) as between coils which are orthogonal to each other. Accordingly, most of the usual problems associated with direct coupling are avoided.

Abstract: ABSTRACT OF THE DISCLOSURE            The phospholes and P-functional phospholes correspond to the general formula:                   in which :  R1 and R2 are identical or different and represent hydrogen or a lower alkyl group of C1 to C4 such as a methyl group, and R3 represents an aryl group (such as -C6H5) or a substituted aryl group (such as -CH2C6H5) or an alkyl group (such as -CH3, -C2H5, -C3H7 to C12H25) or a--(CH2)nz group where Z denotes a function of the -COO-alkyl type (such as -COOC2H5), -CH, -CO-aryl (such as -COC6H5), -CO-alkyl (such as -COCH3) or -OH and n ? 1.   At least one alkyl- or arylhalogeno phosphine is reacted with a butadiene whose carbons in the 2 and/or 3 positions carry possibly a lower alkyl substituent, then subjecting the cyclic adduct resulting from this reaction to the action of a tertiary amine selected from among those having a pKa comprised between 5 and 11, then functionalizing the product obtained if the corresponding P-functional product is desired.  Some of the phospholes thus produced are novel, particularly those of the above formula wherein R3 = -(CH2)nZ such as above defined with n ? 2 for Z = CN.  These novel phospholes are of simpler structural formulas than most known phospholes.  The process disclosed for manufacture of phospholes is less expensive and more efficient than known processes.
