Abstract: ABSTRACT OF THE DISCLOSURE A coolant manifold system for distribution of cool coolant to,  and collection of hot coolant from,  a heat source such as the blanket of a fusion reactor.          The manifold system comprises a number of mani-fold modules disposed around the blanket corresponding to blanket subdivisions.  Each manifold has  an inner duct with  hot,  low-pressure  fluid flow therethrough and an outer duct with cool, high-pressure flow therethrough.  A liner in the inner duct insulates the walls of the inner duct and thereby lowers structural component temperatures, which assists in the support of the manifold.  The overall pressurization of  the manifold causes  the  manifold  to resist  deformation  and  increases  manifold  structural strength.

Abstract: TRIM PRESS                 ABSTRACT OF THE INVENTION           A trim press for severing cup-shaped articles from a sheet of thermoplastic material in which the arti-cles have been integrally formed as by a vacuum forming operation.  A horizontally reciprocable punch is driven to sever articles positioned in a stationary die by a linkage arranged to drive the punch at a relatively slow speed during the severing operation to achieve a smooth shearing separation of the relatively soft thermoplastic material.          The sheet is fed into the die in step-by-step movement through vertical sheet guides fixedly mounted in a treadle which is reciprocated with the punch at a proportionate speed.  A flexible sheet guide connected between the guides in the treadle and a fixed point on the machine frame flexes to accommodate reciprocation of the treadle while contin-uously guiding the sheet to the guides on the treadle. Feed fingers mounted on the treadle advance the sheet to the die in step-by-step movement synchronized with the stroke of the punch.

Abstract: ABSTRACT A hydraulic system (10) for a log grapple device (12), including an unloader valve (20) and an accumulator (22) located downstream of a control valve (18) which determines the direction of fluid flow to the actuating cylinder (108) controlling the opening and closing of the grapple device.  When a predetermined operating pressure is reached the unloader valve diverts outlet flow from a pump (16) to a reservoir (14) and isolates the system downstream of the unloader valve, the accumulator maintaining pressure on the grapple device.  When the grapple device is to be opened, a pilot check valve assembly (60) within the unloader valve permits reverse flow through the unloader valve.

Abstract: ABSTRACT OF THE DISCLOSURE:         Tooth brush having a handle and a bristle head with supports on which tufts of bristles are secured, the supports automatically coming into motion when the user, after applying the bristles against his teeth, gives the brush a reciprocating rectilinear movement, the supports being of a first and of a second type. The supports of the first types are mounted on the housing to allow oscillation of the tufts of bristles thereof in a plane which is perpendicular to the housing when the user applies the aforesaid reciprocating rectilinear movement.  The supports of the second type, on the other hand, are mounted on the housing to allow rotation of their tufts of bristles about their axis of symmetry.  A mechanical interconnecting mechanism joints the supports of the first and of the second type so that oscillation of the support of the first type causes reciprocation of the support of the second type.

Abstract: ABSTRACT    The invention relates to a process and an apparatus for metal arc welding with a consumable electrode.  A pul-sating current is supplied to the electrode from a constant current source.  During the interpulse periods between pulses there flows a minimum current which is at least sufficient to maintain the arc.  The switch from pulse current to interpulse current occurs as a function of the arc voltage, with switching to pulse current occurring if a minimum voltage is detected and to interpulse current occurring if a maximum voltage is detected.          Compared with conventional metal arc welding with a consumable electrode, this method offers the advantage of a better welding quality.

Abstract: A B S T R A C T           The present invention provides a method of con-verting petroleum residues containing a high percentage of asphaltic materials into hydrocarbons of higher commercial value.  The method comprises the steps of viscosity reduc-tion, deasphaltation and hydrotreatment.  The petroleum residues are submitted to a viscosity reduction process under prescribed pressure and temperature conditions.  The resulting viscosity-reduced residue is submitted to a deasphaltation process with aliphatic hydrocarbons saturated at prescribed conditions of temperature, pressure and sol-vent:batch weight ratio to obtain a deasphalted oil and an asphalt.  The deasphalted oil is hydrotreated with catalysts containing certain metals, under prescribed conditions of pressure, temperature, spatial velocity and H2:batch ratio, to obtain liquid products useful as low sulfur content fuels or as a basis for obtaining light distillates or gasolines.
