Abstract: ABSTRACT OF THE DISCLOSURE           A process for the production of beads of a vinyl-aromatic polymer which comprises polymerising a vinylaromatic monomer in an aqueous suspension system in the presence of a suspending agent, a suspension polymerisation catalyst and an alkyl hydrogen poly-siloxane comprising the repeating unit   where R is an alkyl group having from 1 to 4 carbon atoms.          The process reduces the incidence of occluded water especi-ally in portions of the bead adjacent the surface and is particularly useful in the production of foamable polymer beads.

Abstract: ABSTRACT OF THE DISCLOSURE:           A process for purifying-raw gases produced by gasifica-tion of solid or liquid fossile fuels, by treatment with water vapor and oxygen under superatmospheric pressure, in order to remove therefrom catalyst-deteriorating impurities, such as mono- or polyunsaturated hydrocarbons, mercaptans, HCN, HCl, H2S, CS2, COS, and NH3, and to desulfurize the gases, while producing an exhaust gas which is rich in H2S, which process comprises indirectly cooling to ambient temperature the raw gas, which is available at a temperature of 150-170°C, separating and removing therefrom the condensible hydrocarbons, subsequently scrubbing the gas with water to remove ammonia in a first scrubbing stage, in which the water rate is controlled to be just sufficient to remove the ammonia, then scrubbing the gas with a high-boiling organic solvent, which is miscible with water, adding sulfur to that solvent and using it in a second scrubbing stage, in which the solvent rate is controlled in dependence on the solubility of the methylmercaptan, which is to be removed, in the solvent, subsequently adding to the same solvent a soluble activator having a boiling point which is approximatively as high as or higher than that of the boiling organic solvent, adjusting the activator content and using the so adjusted solvent in a third scrubbing stage, in which the water content of the solvent is kept at 5-30 mole percent H2O and in which H2S and COS are entirely and selectively removed from the gas, the scrubbing solvents from the second and third scrubbing stages being separately regenerated and recycled to the second and third scrubbing stages for re-use. The resulting pure gas may be directly used for various chemical syntheses, such as ammonia, methane, methanol, oxosyntheses or Fisher Tropsch syntheses.

Abstract: Abstract of the Disclosure The present invention relates to novel 1,3,4-thiadiazol-2-ylureas characterized by a cyanoalkyl group at the 5-position.  The alkyl group to which the cyano group is attached is always branched, and is preferably branched at the carbon atom adjacent to the ring.  The compounds are also characterized by small alkyl or alkoxy groups on the urea nitrogens.  The new compounds are outstandingly effective herbicides and are also effective, when used at low application rates, in the control of plant pathogens.  They are produced by reacting a 2-alkylamino-5-cyanoalkyl-1,3,4-thiadiazole with an alkylisocyanoate or an alkyl-substituted carbamoyl chloride.

Abstract: ABSTRACT OF THE DISCLOSURE       A method for curing reinforced vulcanizable elastomeric articles disposed between a mold surface and a pressure chamber and articles produced thereby.  The method comprises delivering into the chamber a hot fluid of relatively high heat capacity and pressurizing the fluid to a first pressure; maintaining the fluid in the chamber at the first pressure for a residence period sufficient to at least partially soften the elastomeric article but insufficient to significantly vulcanize the elasto-meric article; while the elastomeric article is in a softened state delivering into the chamber in admixture with the fluid a gas of low heat capacity relative to the hot fluid; pressurizing the gas and fluid in the chamber to a second pressure from about 300 to about 520 psi thereby causing the elastomeric article to flow into' conformance with the mold surface; and thereafter vulcanizing the elastomer article by heating the mold surface.          The method is particularly suited to the production of power transmission belting, and the article produced thereby is characterized by superior wear life.

Abstract: TESTING EMBEDDED ARRAYS                         Abstract A large scale integrated (LSI) chip or semiconductor device includes a memory array and associated logic circuitry.  The array is "embedded" in the sense that it is not directly accessible, either in whole or in part, from the input and output terminals or pads of the device.  To facilitate testing there is added to the device gating means to the memory array and wiring extending from primary access points of the device to the memory array bypassing and in parallel with the logic circuitry.  The device further includes control means operatively associated with the gating means for switching the input to the array between the logic circuitry and the primary access points.  In the latter condition direct access to the array is permitted, thereby facilitating testing.

Abstract: ABSTRACT         An improved chuck actuator assembly includes a fluid motor which is utilized to open and close a chuck.  The actuat-or motor is effective to apply forces to the chuck to hold it closed during rotation of a workpiece.  In the event of an accidental loss of fluid pressure to the actuator motor, a check valve is closed to prevent the exhausting of large quantities of fluid from the motor.  However, as the check valve closes, a small quantity of fluid is discharged from the actuator motor.  The loss of even a small quantity of fluid could tend to cause the chuck to relax its grip on the work-piece.  To prevent this from happening, a compensator assembly is provided to maintain the fluid pressure in the actuator motor chamber substantially constant by making up for the small quantity of fluid which is lost upon closing of the check valve.  The compensator assembly includes a piston which is moved under the influence of a biasing spring.  This move-ment of the piston discharges fluid from an auxiliary chamber into the motor chamber to thereby makeup for the fluid which is lost during the closing of the check valve.  The spring pressure bias against the piston is effective to maintain the fluid pressure in the motor chamber substantially constant so that the forces urging the chuck closed remain substantially constant.  The compensator assembly is advantageously mounted on the main piston in the actuator motor and is rotated with the actuator motor during operation of the machine tool.

Abstract: ABSTRACT       A front projection screen is disclosed which is made from a transparent material.  Prism-like elements are formed on the backside thereof so that light incident upon the screen from a preferred direction will be totally reflected by the screen while light incident upon the screen from other directions will pass therethrough.  Sides of the prism-like elements are curved for dispersion in the horizontal plane while the front surface of the projection screen has segments of cylindrical columns formed thereon perpendicular to the prism-like elements to provide an angular spread in the vertical plane.  The thickness of the screen is between 30% and 70% of the focal length of the cylindrical columns to allow the screen to be tilted in the vertical plane.  Such a screen substantially reduces unwanted relections.

Abstract: A VEHICLE SEAT ASSEMBLY     ABSTRACT OF THE DISCLOSURE        A vehicle seat assembly comprising a substantially horizontal seat structure and a normally upright backrest structure.  The backrest structure is carried on support arms pivotally connected to the seat structure for swinging movement about a fixed pivot axis extending laterally of the latter.       A four-bar linkage adjuster mechanism is interposed between the seat structure and the backrest structure.  The four-bar linkage of the adjuster mechanism terminates in a movable abutment engageable by an abutting portion of the backrest structure.  Under control of the linkage the abutment is movable in the path taken by the abutting portion of the backrest when the latter is swung rearwardly from its normal upright position to a predetermined rearwardly inclined position.        A releasable brake means holds the four-bar linkage and thereby the abutment against movement to block rearward inclination of the backrest structure.  The backrest is forwardly swingable, however, from any position relative to the seat structure independently of engagement with the adjuster mechanism.
