Abstract: ELECTRICAL  CONNECTOR FOR ATTACHMENT TO MULTI-CONDUCTOR CABLES     ABSTRACT     The subject connector includes a hollow body having a plurality of ang-ularly spaced contacts mounted therein.   Each of the contacts has a terminal end for electrical connection to a bare end of one of the conductors of a multi-conductor cable. The hollow body is formed of insulating material and contains compartments which enclose the terminal ends of the spaced contacts. The con-tacts may carry either male blades or female contacts for engagement with mat-ing contacts carried by an opposing connector.   A cap or cover closes a rear end of the hollow body and contains spac-ed funnel-shaped openings which receive and guide the bare ends of the respec-tive contacts. The bare ends of the conductors are clamped in firm electrical contact with the terminal ends by means of a lovable wiring insert. The insert carries cams which engage with and urge movable ends of leaf springs against the bare ends of the conductors and force the conductors against the terminal ends of the contacts in movement of the insert in one direction in the body.  The wiring insert is moved in said one direction against a return spring by a screw which threadably engages with the insert and has a headed end accessible from a front face of the body. The clamping action for a number  of conductors takes place simultaneously in response to turning the single screw in one direction.   Release of the conductors is obtained by turning the screw in the opposite dir-ection. The screw and the spring raise the insert to permit the ends of the conductors to be withdrawn from engagement with the terminal ends of the con-tacts.

Abstract: ABSTRACT 2-Keto-L-gulonic acid is prepared directly from D-glucose by microbial conversion utilizing mixed culturing on or mixed con-tacting with a medium containing D-glucose, employing at least two kind of microorganisms; 2,5-diketo-D-gluconic acid producing strains which belong to the genera of Acetobacter, Acetomonas and Gluconobacter and strains capable of converting the 2,5-diketo-D-gluconic acid into 2-keto-L-gulonic acid which belong to the genera of Brevibacterium and Corynebacterium.  Both the incubation of the microorganisms in a medium containing D-glucose and the direct contact of any products obtained from the cells of the microorganisms with the substrate may be used in the disclosed process.  By-production of the undesired optical isomer, 2-keto-D-gluconic acid, of the intended product is effectively prevented by employing the mixed culturing or contacting because of the presence of the 2,5-diketo-D-gluconic acid producing strain or any products thereof in the medium during at least part of the entire process.

Abstract: ABSTRACT OF THE DISCLOSURE The present invention provides an oil detecting element capable of accurately detecting oil floating on water.  The oil detecting element comprises a water-repellent, oil-passing filtering member for preventing water entering the element.          Oil can be detected by detecting change in the electric resistance of a conductive particle layer due to its contact with oil arriving through the member.  According to an embodiment of the invention, the water-repellent, oil-passing filtering member is impregnated with a material which is toxic to water life such as algae and shells to prevent settling of such water life on the surface of the element and thereby to prolong the life of the element.  Examples of an oil detector incorporating the oil detecting element, including an electrical circuit which detects change in electric resistance of the element upon its contact with oil and actuates a suitable alarm such as a buzzer, are described.

Abstract: ABSTRACT OF THE DISCLOSURE         A method of continuously feeding coal or the like to coal gasifier means or the like operating under a predetermined elevated pressure and of continuously removing ash or the like therefrom in which the coal feeding and ash removing procedures are interrelat-ed to provide energy conservation by removing heat from the ash and transferring the heat to the coal, such energy conservation being performed by means of the liquid medium (water) used to feed the coal and remove the ash.  In the coal feeding procedure, coal is continuously introduced into a first low energy water circuit from which successive volumes of coal particles and entrained water are transferred to a second high energy water circuit during which transfer the first circuit gains water from the second circuit, the second circuit includes a first liquid volume having a free liquid surface maintained at a high pressure level at or near the pres-sure level of the gasifier through which the coal is moved to sup-ply the gasifier.  In the ash removal procedure, a second volume of water having a free surface is maintained at the outlet pressure of the gasifier to receive the discharged ash therethrough, the second volume of water forms part of a third high energy water cir-cuit from which successive volumes of ash and entrained water are transferred to a fourth low energy water circuit, the heated water from the second and third circuits after ash removal therefrom is utilized to supply the loss of water from the second circuit and the excess cool water from the first circuit is utilized to control and maintain, in conjunction with a fresh cool water supply, the tem-perature and level of the second volume.

Abstract: CLOSED LOOP ELECTRO-FLUIDIC CONTROL SYSTEM                  Abstract of the Disclosure Two embodiments of closed loop electro-fluidic con-trolled systems are disclosed for controlling the velocity, acceleration, torque, force or pressure applied to a member.  The system includes a source of electrical command signals correlated-to the desired magnitude of the parameter being controlled, a transducer responsive to the controlled member for providing an electrical feedback signal correlated to the actual value of the parameter, and a circuit for providing an error signal correlated in magnitude and polarity to the magnitude and sense of the difference between the actual and desired values of the controlled parameter.  Also included is a transducer responsive to the error signal for applying a positioning force to a movable valve closure element, which is subjected to no other forces, to regu-late the application of pressurized fluid through the valve to the controlled member in dependence upon the error signal.  No feedback, mechanical, fluidic or otherwise, exists between the valve element and the transducer which positions it.  An important advantage of the system is that the error signal is zero under steady state conditions when the actual and desired magnitude of the controlled parameter are equal nonzero values.  In addition, electrical command offset signals and/or electrical integrators operating on the error signal and/or centering springs operating on the movable valve element are not required.  Nor is feedback required between the movable valve element and the transducer which positions it.
