Abstract: METHOD OF PREVENTION AND REMOVAL OF SULFUR     ABSTRACT OF THE DISCLOSURE           A commercially feasible method is provided for con-trolling depositions of solid sulfur within plant equipment utilized in absorptive-regenerative processes for the removal of H2S from sour gas streams which eliminates costly shut-downs and manual cleaning of the plant equipment and permits removal of solid sulfur therefrom in conjunction with that produced during the regular process itself.  The method com-prises adding ammonia to such H2S removal systems during running thereof in order to solubilize any solid sulfur and remove the same with the sulfur produced by circulating alkali absorption solution employed.  Ammonia may be added to either the sour gas stream or directly to the absorption solution, and more-over can be added intermittently to remove preexisting sulfur deposits or on a semi-continuous basis as needed to substan-tially prevent undesirable sulfur buildup.  The present method finds application in connection with known desulfurization pro-cesses such as the Stretford, Ferrox and Takahax.

Abstract: ABSTRACT         A blocking circuit for thyristors comprises a DC power source coupled to a capacitor which is switched into a thyristor circuit by a switching transistor and a pair of auxiliary thyristors.  A high power current pulse from the capacitor is applied to the thyristor for blocking purposes.          A common blocking circuit may be switched into a plurality of thyristor circuits eliminating separate capacitors and power sources, a separate pair of the auxiliary thyristors being provided for each thyristor circuit to be controlled.          In a second embodiment, a high power DC output voltage would be generated from a three phase current source by means of three full wave rectifiers coupled to achieve a charging process six times per cycle.  This latter arrangement offers the possibility of saving the charging capacitor altogether as the rectified phases overlap with only a slight ripple.

Abstract: ABSTRACT OF THE DISCLOSURE        A dispatch indicator is disclosed for a vehicle or other merchandise-enclosing container to provide shipping instructions therefor.  The indicator includes a horizontal shaft having a control knob for rotation and also limited axial sliding movement of the shaft, and a relatively large diameter circular rear dial plate and a relatively small diameter circular front dial plate coaxial with the shaft and having centrally disposed openings through which the shaft loosely projects, the rear dial plate presenting indicia sectors which are visible through a first viewing opening in a housing of the indicator, and the front dial plate presenting indicia sectors which are visible through a second viewing opening in the housing.  The front and rear dial plates are yieldingly biased apart against a fixed front reaction plate and a fixed rear plate, respectively, each dial plate being centrally formed with radially extending clutch recesses with which a clutch finger mounted on the shaft is selectively cooperable depending upon the axial position of the shaft, with the shaft being yieldingly biased to a medial position in which the clutch finger is out of effective engage-ment with the dial plates.  A circular row of detent depres-sions and a series of fixed cooperating detent protuberances effective between each dial plate and its associated fixed reaction plate restrains rotational movement of such plate when an indicia sector thereon is in register with its associated viewing opening.

Abstract: MICROMIST JET PRINTER                ABSTRACT OF THE DISCLOSURE    A micromist printing arrangement wherein a micromist of ink particles, provided by an ultrasonic nebulizer, is forced through a small nozzle to form an aerosol jet.          The micromist ink particles are entrained in the jet and focused to print a narrow width region which is substan-tially smaller in size than the overall jet diameter and the nozzle opening.  Particle size, jet stream velocity and air or other carrier gas viscosity are considered in establishing focusing characteristics of the aerosol jet, which is directed against the paper to wet the same, thereby obtaining dense, well defined print lines.  Accord-ing to a first embodiment, modulation of the aerosol jet is achieved by fluid logic control whereby a vacuum is introduced into the path of the aerosol jet to shunt it from its printing path.  In another embodiment, control may be achieved through the use of sonic excitation of turbulence into the aerosol jet.  The sonic excitation changes the aerosol jet from laminar flow to turbulent flow, resulting in a reduction of the velocity of the aerosol jet such that the aerosol ink particles do not wet the paper.

Abstract: ABSTRACT OF THE DISCLOSURE      The specification describes a method and apparatus for producing a highly pure metal powder from a rod-shaped metal feed material.  The feed material is progressively melted down by heating it with an electron beam in a vacuum.  The molten material which is thus formed is temporarily intercepted on a high speed centrifugal plate which throws off particles of the molten material.  The material on the centrifugal plate is exposed to the focal spot of an electron beam which has a diameter several times less than the diameter of the plate.          The electron beam is controlled and deflected between the centre of rotation and the peripheral edge of the plate result-ing in the focal spot of the beam sweeping a radial zone above the spinning plate.  The particles thrown off the plate are then cooled substantially by radiation to the point of solidification.  This particular method produces a highly pure metal powder having a precisely defined particle distri-bution that  is required for metal coatings and/or the formation of a number of super-alloys.

Abstract: RADIO RECEIVER BLANKER GATE                         ABSTRACT    A balanced, doubly tuned gate couples between the mixer and intermediate frequency (IF) stages of a conventional radio receiver.  The network is comprised of a pair of matched transformers interconnected in a balanced configu-ration, with the first transformer tuned to the mixer and the remaining transformer tuned to the IF stage.  Capacitors interconnect the two transformers resulting in a Butterworth filter network.    Two diode pairs connect in shunt across selected wind ings of the transformers.  Direct current bias normally biases the diodes to a nonconducting state, thereby allowing the mixer signals to pass to the IF stage.  A blanking signal from the receiver blanker drives the diodes to conduc-tion thereby decoupling the mixer from the IF and blanking the receiver.    Due to the doubly balanced nature of the gate, blanking is accomplished with a minimum of switching time.  Moreover, the shunt diode switching scheme provides superior attenua-tion in the blanking mode and enhanced operation in the normal mode.

Abstract: ABSTRACT OF THE DISCLOSURE              This invention relates to electrical contact members employing insulation opening or penetrating means which are enabled to complete electrical connections when an insulated conductor is installed in the contact member. In the prior art, insulation opening slots terminate in an open extremity at one end of the contact and the insu-lated conductor is introduced through that open extremity. There is no provision in this prior art for admitting the insulated conductor through the wall of the contact and no way in which the conductor may be twisted around the slot and through the contact.  Other prior art connectors suffer from being formed of two or more distinct parts. The present invention overcomes these problems by provid-ing an electrical contact member formed from an axially extended tube having intermediate its ends an axially extending insulation-opening slot.  The slot is terminated at one end in an entry opening through the tube.  The entry opening and an inwardly tapered entry ramp are formed by a free-ended piece of the tube wall bent into the inner opening of the tube.  The tube at a section apart from the slot may be crimped to secure the conductor after the conductor is positioned in the slot.  A contact member or plurality of contact members may be assembled with insulating means to form a connector.
