Abstract: WIDEBAND PHASE LOCKED LOOP SIGNAL  CONDITIONER FOR RADIO ALTIMETER                  Abstract of the Disclosure A wideband phase locked loop oscillator (PLLO) for tracking the frequency of an altitude signal in an FM/CW type radio altim-eter.  The phase locked loop oscillator conventionally includes a voltage controlled oscillator (VCO), a phase comparator for compar-ing the phase of the altitude signal to be tracked with the phase of the VCO output and an error signal amplifier for applying the output of the phase comparator as control voltage to the VCO.  The frequency range of the PLLO is extended by changing the natural frequency of the VCO in steps spanning the useful frequency range of the altitude signal.  Selection of the proper value of VCO natural frequency is effected through microprocessor directed digi-tal control.

Abstract: Abstract of the Disclosure A hydraulic control system comprising a hydraulic actu-ator having opposed openings adapted to alternately function as inlets and outlets for moving the element of the actuator in opposite directions, a pump for supplying fluid to said actuator, pilot operated meter-in valve to which the fluid from the pump is supplied for controlling the direction of movement of the actuator, and pilot operated meter-out valve associated with at least one opening of the actuator for controlling the flow out of said actuator.  The pressure of fluid being supplied to the actuator by the meter-in valve means is sensed and caused to produce a force opposing the movement of the meter-in valve means by the pilot pres-sure and also applied to a device for controlling an over-hauling load resulting in a smooth and accurate control of the movement of the actuator.

Abstract: Abstract Organomagnesium compounds represented by the formulas:       (I)         (II) in which R is a straight or branched chain alkyl group including alkyl groups of about 1-18 carbon atoms, aryl groups of about 6 to 14 carbon atoms, and the R groups are the same or different.  The alkyl or aryl R groups are preferably unsubstituted but may have inert substituents that are nonreactive to the highly reactive Mg-N bonds, preferred substituents being ether groups, tertiary amine groups, chloride and fluoride groups and combinations of these, R' is R or hydrogen, Y groups are R or -SiR?, all R' groups are the same or different, all R groups are the same or different and all Y groups are the same or different.  These compounds may be used in the synthesis of tertiary alcohols from ketones since they diminish secondary alcohol and enol formations.  They may also be used as catalysts with polymerization of 1-olefins.

Title: Apparatus for the pelletization of heat liquifiable  solid materials
Inventor: ORLANDER MICHAEL
IPC: C04B5/02
Filed: 1983-04-27
Granted: 1985-03-19
Abstract: ABSTRACT OF THE DISCLOSURE         Apparatus for the pelletization of heat liquifiable materials, such as metallurgical slags consists of a downwardly-extending feed plate onto which the molten material is fed together with water, if required to promote the expansion of the molten material and for control of the cooling.  The material discharges from the feed plate onto a rotating radially vaned drum or rotor by which it is projected into the air for simul-taneous cooling and pelletization after it has first passed through a flow control gap formed between the feed plate surface and the periphery of a second rotor mounted above the feed plate The second rotor is rotated in the direction such that it pro-motes the flow of the molten material down the plate, forcing the material between the vanes of the projecting rotor, while at the same time spreading the material across the width of the plate against its natural tendency to form a compact stream.          The flow of the material is thereby made more uniform, providing for more effective use of the projecting rotor and avoiding localized flooding of the vanes with consequent loss of pelletization.  The resulting apparatus can also be more compact for a given output.  In some circumstances the second rotor can with advantage be rotated against the direction of flow down the feed plate.

Abstract: ABSTRACT OF THE DISCLOSURE    A calorimeter and method of obtaining the calorific value of a test gas comprises a pair of constant flow pumps one for supplying air at known volumetric flow and the other for supplying a test gas at known volumetric flow.  The known volumetric flow of air if maintained at a level sufficient to provide enough oxygen to fully burn all oxidizable components of the test gas. The air and test gas are mixed and catalytically burned in a heated block and the combustion products are thereafter supplied to an electrochemical oxygen measuring cell which measures the remaining oxygen in the mixture.  A circuit arrangement is utilized to obtain a value pro-portional to the difference between the remaining oxygen and original amount of oxygen which value is proportional to the amount of oxygen util-ized and in turn proportional to calorific value of the test gas.

Abstract: ABSTRACT OF THE DISCLOSURE           A signal translating circuit is disclosed in which an input signal is supplied to a source follower transistor, a bootstrap capacitive component is presented between the gate and source of the source follower transistor, the signal from the source follower transistor is supplied through a first transmis-sion gate to a next stage, and also led out to an output terminal.          Further, the circuit formed of the source follower transistor and the first transmission gate is sequentially connected and the source follower transistor and the first transmission gate are alternately driven with different phases to each other whereby the input signal is sequentially transmitted at each stage.          Furthermore, a second transmission gate is connected between the output terminal of the source follower transistor and the ground in which after the output signal at the output terminal rises up and falls down once, the second transmission gate is turned on by the signal relating to the output from the stages following the succeeding stage to thereby make the level of the signal when the output signal at the output terminal falls down stable.          Thus, undesired potential fluctuation is not generated on the output line.
