Abstract: ABSTRACT OF THE DISCLOSURE          The present invention relates to a process for making compounds having the formula (I):                             (I) wherein R1 represents a methyl, phenyl, piperidino, 1-pyrroli-dinyl, morpholino or 4-methyl-1-piperazinyl group, an alkyl or alkoxy group having from 1 to 4 carbon atoms, an amino group, a substituted amino group of the formula NHR' (wherein R'  repre-sents an alkyl group having from 1 to 4 carbon atoms, a cyclo-alkyl. group, a benzyl group, or a phenyl group) or a substituted amino group of the formula NR" R" I (wherein R" and R"' both represent alkyl groups having from 1 to 4 carbon atoms);         R2 represents a hydrogen atom, an alkyl group having from 1 to 4 carbon atoms, or a phenyl group;         R3 represents a fluorine atom, a cyano, difluoromethyl, difluorobromomethyl, trifluoromethyl, methylthio, methylsulphonyl or sulphonamido group, an alkoxy group having from 1 to 4 carbon atoms, an acyl group having from 2 to 4 carbon atoms, or a benzoyl group;     R4 represents a hydrocarbon group having from 1 to 4 carbon atoms;         R5 represents a hydrogen atom or a methoxy group;         R6 represents a hydrogen or halogen atom or a methyl group; and R7 represents a hydrogen atom or a methyl group.  The 2-cyano derivatives are especially preferred.  The compounds of the general formula (I) as defined hereinbefore are useful as antihypertensive agents and have moderate to good anti-prolactinic activity, while exhibiting fewer and more reduced side effects as compared with prior art preparations.  When compared to the prior art preparations, they exhibit a good therapeutic ratio, the same or lower LD50 and reduced variations of heart rate.

The assembly includes temperature-controlled member, preferably cylindrical in shape, having a closed end and an open end.  The open end is fit-ted with standard threads to facilitate attachment of the nozzle member to the feed barrel of a conventional screw-type molding ma-chine.  The nozzle member has an internal temperature controlling means and a plurality of feed outlets positioned on the periphery of the nozzle member near the closed end.  The temperature main-tained in the nozzle member is sufficiently high to maintain the thermosetting molding material within the nozzle member in a plas-ticized state and sufficiently low that no substantial curing of the thermosetting molding material takes place.  In an alternate mode, the assembly includes a sleeve member positioned around the periphery of the nozzle member and moveable to cover and uncover the feed outlets in the periphery of the nozzle member.  In such alternate mode, means are provided to move the sleeve member from a position wherein the feed outlets are covered when the mold faces are open to a position wherein the feed outlets are uncovered when the mold faces are closed.

Abstract: ADJUSTABLE LABOR-DELIVERY-RECOVERY HOSPITAL BED        Abstract:      The same hospital bed may be employed for labor, delivery and recovery by providing two different adjustable back support sections (33a,33b) in the mattress supporting structure.  The expectant mother occupies the entire bed during labor and one back support (33a), at the head end of the bed, may be tilted upward to raise the patient's back and head to maximize comfort.  Prior to delivery, the patient is moved to the foot end of the bed and a second back support (33b) is tilted upward so that the patient will be held in a semi-sitting optimum position for delivery.  The patient's legs may be held at a desired elevated level by a pair of crutches (65). In effect, the bed is convertible from a somewhat conventional hospital bed to an obstetrical table. After delivery, the second back support may be lowered so that the entire bed may then be used by the patient for recovery.

Abstract: ABSTRACT OF THE DISCLOSURE          A magnetometer is moved along the route of a pipeline and the output of the magnetometer is observed to identify pipeline characteristics.  Used with a buried pipeline the magnetometer is moved over the surface of the overlay to identify and locate girth welds, pipeline fittings and accoutrements, changes in pipeline metallurgy such as occur with large hard spots and changes in wall thickness as occur in extensive and severe corrosion.          Similar functions can be performed with underwater pipelines using a magnetometer which is located in an appropriate container and trolled along the route of the pipeline by a vessel.  The pipeline is formed of pipe sections which are arranged in an identifiable pattern according to their magnetic characteristics to facilitate inspection and maintenance.

Abstract: ROTARY ELECTRICAL JUNCTION ASSEMBLY                       Abstract A rotary electrical junction assembly includes a rotor and a stator which are each separable into halves to facilitate installation and maintenance thereof.  In a preferred embodiment, the rotor includes a plurality of brushes, and the stator includes a plurality of split slip rings engaged by the brushes.  The slip ring halves are interconnected with corresponding ring halves and are positioned on individual non-conductive backing members which are stacked together to form slip ring stack halves.  The slip ring stack halves are mounted on the stator halves which are clamped onto a stationary support member.  The backing members are semi-circular, and each includes a circumferential wall to separate and insulate each slip ring from an adjacent slip ring.  Each insulator wall has opposite ends which extend past an associated ring half and overlap the ends of a corresponding wall in the opposite stack half to provide continuous insulation between the slip rings.  The brushes are mounted on brush racks which have rollers that engage tracks on the stator.  A split outer housing provides protective cover for the rotor and stator and recesses receiving the brush racks.  The housing is clamped onto a rotary support member rotatably engaged with the stationary support member whereby the brush racks revolve about the stator upon rotation of the rotor support member, thereby providing continuous conductive contact between the brushes and slip rings.  In another embodiment, the stator includes a plurality of brushes and the rotor includes a plurality of split slip rings whereby the rings revolve around the brushes and provide continuous conductive contact.

Abstract: GC108+         ABSTRACT            Liquid Detergent Compositions The present invention relates to aqueous alkaline built detergent compositions containing hydrogen peroxide. Alkaline conditions present particular difficulties for preventing the hydrogen peroxide from decomposing excessively rapidly during storage.  Aqueous compositions containing a builder, especially polyphosphate or citrate, anionic sulphate or sulphonate surfactant, nonionic ethoxylate surfactant and hydrogen peroxide of acceptable peroxide stability can be obtained by employing an alcohol, preferably ethanol, or a polyhydroxy carboxylate, preferably gluconate, or especially both, in conjunction with a phosphonate, especially an ethylene amine methylene phosphonate.  Many of such alkaline compositions are formulated to permit the anionic surfactant to work at or near to its optimum pH in conjunction with the builder.  The invention also provides similar, but unbuilt compositions containing instead of the builder, additional surfactant, generally nonionic surfactant, and having a somewhat lower pH.

Abstract: METHOD AND APPARATUS FOR OPTICAL FIBER FAULT LOCATION       Abstract of the Disclosure A discontinuity within a fiber is located using a reflectometry technique.  A swept frequency sinusoidal signal is launched into the fiber from one end and propagates along the fiber.  If the discontinuity is reflecting the signal is reflected, while if non-reflecting, backscatter is markedly reduced.  Both conditions can be monitored when a signal returned to the fiber input end interferes constructively or destructively with the input signal depending on the phase difference between them.  Both the amplitude and phase of the resulting interference signal vary periodically with frequency.  From the periodicity, the distance from the input end of the fiber to the discontinuity can be derived.
