Abstract: STRAW SPREADER            ABSTRACT OF THE DISCLOSURE         Straw spreaders are normally controlled manually by the operator and it is therefore extremely difficult to continually adjust the speed of the spreader so that the straw layer is reasonably even because the density of the straw varies continuously across the average field. The present device includes a rheostat sensor at the straw walker that controls the speed of the orbital motor driv-ing the spreader blade assemblies.  This results in a re-latively even spread of straw taking place regardless of the variation in straw density as the motor slows down under a light load and speeds up when heavy straw is en-countered.  The operator can, of course, control the on/ off functions from the cab if, for example, it is desired to spread alternate swaths.

Abstract: Abstract of the Disclosure A hydropyrolysis process for upgrading heavy, high molecular  weight  feedstocks  such  as  coal-derived liquids, petroleum crudes,  tar sand bitumens,  shale oils, bottom residues from process streams, and the like,  to  lighter,  lower  molecular  weight  liquid products.   The  process   includes   subjecting  the feedstocks to pyrolysis in the presence of hydrogen under carefully controlled conditions of temperature and pressure.  The process  can be  defined as hydrogen-modified, thermal cracking in the specific temperature range of 450°C to 650°C and in the hydrogen pressure range of about 120 psi to 2250 psi.  The amount of hydrogen present can be varied according to the type of feedstock and the liquid product desired.  Although the hydrogen is not  consumed in large amounts,  it does participate in and modifies the process, and thereby provides a means of controlling the process as to the molecular weight range and structural type distribution of the liquid products.  The presence of hydrogen also inhibits coke formation.  The process also eliminates the requirement for a catalyst so that the reaction will proceed in the presence of heavy metal contaminants in the feedstock which contaminants would otherwise poison any catalyst.

Abstract: ABSTRACT OF THE DISCLOSURE            The invention provides an electrophotographic device by which the surface potential of a photosensitive member is substantially uniformalized at the time of termination of the photocopying process by rotating through one revolution the photosensitive member after completion of the copying process and subjecting the photosensitive member to A.C. corona discharge or light exposure.  Moreover, a reflecting mirror and an in-mirror lens are integrally rotated so as to adjust the light path length to obtain the most effective exposure.  Furthermore, the ratio of width of the central portion and of both end portions of the slit for exposure can be varied to obtain a uniform and effective exposure.

Abstract: ABSTRACT OF THE DISCLOSURE          An  improved method and apparatus for recording and playing back a video signal on a video disc, such that selected video frames can be played back in a stop-motion fashion, with accompanying audio.   Each stop-motion video frame is recorded on a single recording track on the disc, and an associated digitized stop-motion audio signal is combined with a continuous-play video signal and recorded on a plurality of preceding tracks.  During playback, the tracks recording the continuous-play video signal are first scanned, to recover and display the contin-uous-play video frames, and to recover and enter into a memory the digitized stop-motion audio signal.  The track recording the corresponding stop-motion video signal is then scanned, in a repeated fashion, to provide a stop-motion display of the video frame, while the stop-motion audio signal is extracted from the memory and converted back to its original analog format, for playback along with the stop-motion video frame.

Abstract: ABSTRACT OF THE DISCLOSURE           An improved method and apparatus for froth flotation separation of the components of a slurry, having particular utility for the beneficiation of coal by the flotation separation of coal particles from impurities associated therewith such as ash and sulfur.  In this arrangement, a spray nozzle is positioned above a flo-tation tank having a water bath therein, and sprays an input slurry through an aeration zone into the surface of the water.  The spraying operation creates a froth on the water surface in which a substantial quantity of particulate matter is floating, while other components of the slurry sink into the water bath.  A skimming arrangement skims the froth from the water surface as a cleaned or beneficiated product.  Moreover, a recycling operation is provided wherein particulate materials which do not float after being sprayed through the primary spray nozzle are recycled to a further recycle spray nozzle to provide a second opportunity for recovery of the recycled particles.

Abstract: Abstract A controller for controlling fluid flow from a source to a motor, such as the steering motor of a motor vehicle.  The controller includes a metering section and a control valve section comprising a stacked assembly of plate valve members which control flow and, along with the metering section, define the outer periphery of the controller, and minimize the need for complex cast housing members.  The controller is compact and yet is constructed to respond to an input signal from an input shaft to direct needed flow from the source to the primary steering motor, and excess flow to an auxiliary motor.  The controller is also characterized by a unique spring centering mechanism which applies a spring centering force to the assembly of plate valve members.  Additionally, the controller is characterized by a special seal arrangement for resisting leakage of high pressure fluid about the input shaft, and by structure for forming pressure dams to resisting leakage of metered fluid.
