Abstract: ABSTRACT OF THE DISCLOSURE:       The invention is concerned with a process of directly reducing iron oxide-containing material to produce sponge iron in a rotary kiln by a treatment with solid carbonaceous reducing agents having a high content of volatile combustible constituents, in which the charge is moved through the rotary kiln opposite to the direction of flow of the kiln atmosphere, oxygen-containing gases are blown at controlled rates through nozzle blocks into the charge disposed over nozzle blocks in the heating up zone in that region thereof which begins with the occurrence of ignitable particles of the solid reducing agents and terminates before the reducing zone, and oxygen-containing gases are blown at a controlled rate through shell tubes into the free kiln space at least in that region.  The process of the invention is characterized in that the solid carbonaceous reducing agent consists at least in part of disintegrated waste rubber.  The advantages afforded by the invention reside in that a direct reduction can be effected in an economical and simple manner with waste rubber as inex-pensive reducing agent and fuel whereas an additional process step is  not required.  Besides, the problems and casts related to a dump for waste rubber or to another processing of waste rubber can be avoided without need for an additional expendi-ture.  The zinc contained in automobile tires can be recovered for utilization, and the iron content is included in the sponge iron so that the processing of the waste rubber does not result in waste products.

Abstract: PROCESS AND SYSTEM FOR RECOVERING                SOLID PARTICULATE ADDITIVES FROM                       A DRILLING FLUID     ABSTRACT OF THE DISCLOSURE             A  process and system is provided permitting the recovery of solid particulate material, particularly solid copolymer beads, from a drilling fluid which also contains drilled solids of the same and larger size as the particulate material.  The drilling fluid returns are passed to a separator, such as a shale shaker, which screens from the fluid a major proportion of the drilled solids along with the particulate material.  The latter fraction is then passed into a vessel containing a weighted liquid having a specific gravity less than that of the drilled solids but greater than that of the particulate material.  In such vessel, the particulate material is allowed to rise to the surface of the liquid while the drilled solids settle therein.  The particulate material can then be skimmed from the upper portion of the vessel and returned to the will for recirculation therein.  To conserve the weighted liquid, the particulate material removed from the vessel can be passed through a separator to separate it from any weighted liquid so that the  latter can be returned to the vessel.   Similarly, the drilled solids removed from the vessel can likewise be separated from any weighted liquid removed with them and the liquid returned to the vessel.     * * * * * * * * * * * * * * *

Abstract: ABSTRACT OF THE DISCLOSURE An arrangement for controlled engagement of the tools of a mining machine, especially a coal planer, with a mine face comprises an abutment, for instance a scraper conveyor, provided on its front face directed toward the mine face with a guide rail guiding the mining machine for reciprocation in substantially horizontal  direction along the mine face and a mechanism for tilting the abutment and the mining machine guided thereon about a sub-stantially horizontal axis.  The tilting mechanism is connected to the rear face of the abutment and extends in its entirety rearwardly of the rear face of the latter.  The tilting mechanism comprises a guide linkage pivotally connected at its front end to the rear face of the scraper conveyor while its rear end portion forms a housing for a fluid operated cylinder and piston unit, the piston rod of which is connected to a connecting rod guided by the guide linkage for movement in longitudinal direction and having an upwardly extending front section pivotally connected at its upper free end to the above mentioned rear face of the scraper conveyor.  The tilting unit, that is the fluid operated cylinder-and-piston unit is thus considerably spaced from the scraper conveyor and the material transported thereby and especially coal dust raised during transport of the mined coal by the conveyor, whereby maintenance of the tilting unit is reduced.  In addition, the guide link-age, the connecting rod and the tilting unit are all in close proximity to the sole of the mine gallery to leave a considerable free space between the arrangement and the roof of the mine gallery.

Abstract: ABSTRACT    A method of producing endless drive belts of natural or synthetic rubber with thread-like embedded strength carriers which preferably extend in the longitudinal direction. This method relates especially to multiple V-belts and similar belts having longitudinal ribs extend-ing continuously over the inner periphery or circumfer-ence thereof.  A raw belt member is built up in upside-down sequence of layering, and is placed into an outer form or mold, in which it is formed-out and vulcanized.  The belts are then turned or folded or rolled over into the use condition thereof. The raw belt member, which is pro-duced oversize with respect to the outer form or mold, is retracted, pulled-in, or drawn-in to an outer diameter cor-responding to the smallest inner diameter of the outer form, and is expanded within the outer form to, or essentially to, the original outer diameter thereof.  The raw belt member may be subjected to a pressure drop effective from the out-side toward the inside for retracting, pulling-in, or draw-ing-in the diameter thereof.  The raw belt member has strength carriers of synthetic polymers which shrink in the heat, and may be subjected to an elevated temperature for retracting, pulling-in or drawing-in the diameter thereof.

Abstract: ADAPTIVE AUDIO COMPRESSOR                         ABSTRACT    An amplitude modulated transmitter includes an audio amplifier which, via a radio frequency (RF) power supply modulator, modulates an RF amplifier and carrier.  Fluctua-tions in the direct current DC bias to the RF amp, such as are common in mobile applications, vary the modulation index of the transmitted signal.    To minimize DC bias affects on the modulation index, the invention contemplates an audio compressor which senses both audio signal level and DC bias level and, in response thereto, controls audio signal compression to maintain the desired percent modulation.  Compression is effected by changing the bias on a semiconductor device which, in turn, attenuates audio signals at the input of a fixed gain audio amplifier.  A feedback path around the audio amplifier senses both DC voltage and audio signal level and produces an appropriate control signal to bias the semiconductor device, thereby altering audio compression.

Abstract: RCA 73,996 Abstract of the Disclosure Apparatus is disclosed in a video signal processing system for automatically monitoring and controlling the blanking (black) current level of an image reproducing kinescope having cathode and grid intensity control electrodes.  When cathode blanking current is monitored, a reference voltage is applied to the cathode over the entire monitoring interval, and an auxiliary voltage is applied to the grid electrode during a portion of the monitoring interval.  A version of the grid voltage appears as an induced cathode output voltage proportional to the level of cathode blanking current conduction.  A voltage responsive sensing network coupled to the cathode provides an output voltage proportional to the difference in cathode current conducted over the monitoring interval. This voltage is processed by a sampling network to produce a control voltage for modifying the cathode bias in a direction to produce the desired cathode blanking current level at or in the vicinity of kinescope cut-off. The sampling network includes two similar time sequential sample and hold circuits.  The first circuit samples the induced cathode output voltage, and the second circuit subsequently samples the cathode reference voltage.  The sampled voltages are differentially processed to remove unwanted common mode interference signals from the control voltage.
