Abstract: SHEET ROLL SPLITTER HAVING HORIZONTAL CUTTER    Abstract A roll splitter apparatus is described for splitting a roll of paper or other sheet material using a cutter blade which moves substantially horizontally toward the roll core.  A pair of generally horizontal extending holding arms are provided with hooks on the ends of such arms which engage a shaft extending through the core of the sheet roll to hold such roll while the cutter blade is moved radially inward toward the core to cut the roll.          The cutter blade is driven by a fluid cylinder and has guide members which slide along the holding arms to guide the movement of such blade.  The holding arms and blade are raised and lowered by means of another fluid cylinder in order to accomodate rolls of different diameter.  A knife guard is provided which covers the cutter blade in its retracted position, such guard being raised and lowered by cams provided on the blade.  The entire roll splitter apparatus is mounted on a wheeled cart for mobility, such that the apparatus can be positioned adjacent the paper machine from which the unused rolls are taken and split before being turned back into pulp.

Abstract: MARINE PROPULSION CONTROL TRANSFER SYSTEM                 Abstract of the Disclosure A plurality of single lever control stands are provided at remote locations for controlling a pneu-matically operated marine propulsion system. Control of the propulsion system is transferred between the several control stands by connecting each stand to a source of supply air under pressure. The control stands each include a throttle valve which will produce a set of three pres-sure signals. A valve located at each stand must be actuated by an operator at that location before the air supply will be activated for that station. Two of the signals select the ahead and astern direction of motion for the vessel and the third signal varies in propor-tion to the throttle lever position and controls engine speed. Banks of shuttle valves receive pairs of sets of these pressure signals and pass onto the control the signals at the higher pressure level. The system includes transfer valves at the main and secondary stations which cannot be overridden by stations of lower priority.

Abstract: METHOD OF PREVENTING FOULING OF        HOT SEPARATOR IN HYDROCONVERSION           OF HEAVY HYDROCARBON OILS            Abstract of the Disclosure The operation of a hydrocracking process to recover valuable liquid hydrocarbons from heavy hydro-carbon oils, such as heavy bituminous oil extracted from tar sands, is significantly improved when the downstream liquid-gas separator is operated at the pressure of the hydrocracking stage and the effluent from the hydro-cracking stage is introduced into the liquid-gas separator below the liquid level in the separator.  This reduces settling of mineral matter contained in  the effluent, prevents phase separation of the hydrocarbon liquid in the separator, reduces hydrogen starvation thereby preventing polymerization and coking of the hydrocarbon liquid in the separator and substantially eliminates sludge formation in the separator and plugging of the liquid outlet.

Abstract: PHOTOVOLTAIC CELL MANUFACTURE            Abstract of the Disclosure A quality control technique is based on the observation that trapping centers contribute to inefficient operation of junction devices.  Devices are irradiated by a first radiation source of intensity sufficient to populate traps and a second radiation source of varying wavelength.          Trapping centers are detected by a deviation from the expected photovoltaic output-incident wavelength relationship.  Such "structure" is utilized as the basis for altering production conditions to minimize currents of such centers.  While the procedure is of general applicability, it is particularly suitable as applied to photovoltaic cells.

Abstract: 20-TR-1216 A control system for a self-excited alternator which includes an auxiliary winding adapted to supply excitation to the alternator field winding incorporates a circuit for supplementing field excitation when the available energy from the auxiliary winding is less than the desired magnitude of field excitation. The self-exciting a-c current from auxiliary winding is coupled through a phase-controlled rectifier circuit to the alternator field winding. A secondary excitation source such as a battery is coupled to the alternator field winding through a chopper circuit. A regulating circuit is responsive to a field current reference signal for controlling the conduction of the phase controlled rectifier circuit and the chopper circuit in a manner to regulate the alternator field excitation to the desired value. The regulating circuit is adapted to supplement the situation supplied by the auxiliary winding with excitation from the secondary source until the excitation available from the auxiliary winding is sufficient to supply the desired magnitude of alternator field excitation.

Abstract: YARN STRIPPER            Abstract of the Disclosure Disclosed is a plate-like yarn stripper device for use in removing staple fiber yarns from rotatable elements of circular cross-section, such as in the removal of yarn wraps underwound beneath a spindle blade to anchor the yarn threadline in the doffing and donning of cops on a ring spinning frame. The stripper is formed with a central hole defining stripping edges at a sur-face of the plate, these edges being spaced from the yarn-wound element by a prescribed distance such that when the element is rotated the wound yarn will buffet the edges and be abraded, weakened and cut or otherwise severed in the stripping action. Personnel safety is enhanced in use of the stripper by the absence of periph-eral sharp edges, bristles or other abrasive external surfaces.

Abstract: ABSTRACT            The present invention relates to deuterium iso-tope separation and enrichment.  Presently, multi-stage equilibrium partition methods are employed to concentrate naturally occurring deuterium.  Such methods involve bulky equipment and large materials handling problems because of low enrichment factors per stage.  Therefore, there is low throughput and long time periods involved in order to attain steady state equilibrium conditions.  The present invention overcomes these deficiencies by providing a method of separ-ating deuterium from certain normally commercially available sources such as ethylene, vinyl chloride, 1,2-dichloroethane and propylene using tuned infrared lasers to selectively decompose such compounds into enriched molecular products containing deuterium atoms.  The deuterium containing mole-cules can be easily separated from the starting material by absorption, distillation or other simple chemical separation techniques and methods.  After evaporation such deuterium containing molecules can be burned to form water with an enriched deuterium content or pyrolyzed to form hydrogen gas with an enriched deuterium content. The present inven-tion results in obtaining amounts of deuterium or heavy water as a valuable by-product from commercial chemical process.
