Abstract: Apparatus is disclosed for collecting plasma. The blood collected at from a blood access is temporarily stored in a blood reservoir and subsequently allowed to pass through a plasma separator at increased speed per unit time by the action of circulating pump located downstream of the reservoir. The plasma separator is connected at its outlet to a circuit communicating with the blood reservoir, whereby the blood cells substantially free of plasma are combined with a fresh feed of blood from the blood access. Blood cells of higher Ht values, while in blood return, come predominantly out of the plasma separator so that the latter involves no sudden increase in pressure.

Abstract: A degassing apparatus, adapted for use in a molding apparatus having a mold cavity, includes a spool having a bore, a gas inlet opening and a gas outlet opening. The gas inlet and outlet openings are in selective communication and non-communication with each other. A reciprocatingly slidable valve body engages a conforming valve seat formed on the spool for selectively controlling the communication and non-communication between the gas inlet and gas outlet openings. A piston is mounted in the bore and coupled to the valve body. The piston is reciprocatingly slidable between a first position and a second position. First and second chambers are situated on opposite axial sides of the piston. First, second and third fluid ports are formed in the spool. The first and second ports are in communication with the first and second chambers, respectively.

Abstract: A method of controlling the speed of a piston in an injection molding or die casting machine utilizing a flow rate change characteristic inherent in a hydraulic pressure circuit including a cylinder and a flow rate adjusting valve. The characteristic effects the operation delay due to the compressibility and inertia of the oil and other factors, in changing the speed or the flow rate of a operation oil from a lower value to a higher value. The characteristic is formulated in time or piston stroke expressed by a function of the speed or the flow rate between the lower and higher values under an actuation pattern of the valve in which the valve opening is forced to change at a constant velocity.

Abstract: A floating bush bearing comprising: a pair of an outer member having a cylindrical inner surface and an inner member having a cylindrical outer surface which is inserted in the outer member substantially coaxially, one of said pair of outer and inner members being rotatable and another member being fixed; a floating bush having inner and outer cylindrical surfaces fitted between the outer and inner members; a substantially cylindrical hole which is defined by opposed substantially semicylindrical outer and inner grooves which are formed in the opposed surfaces of the rotatable member and the floating bush; and a small cylindrical pin which is fitted into the hole.

Abstract: A polypropylene composition useful for producing a shaped article, for example, a bumper, having excellent rigidity, resistance to mechanical impact at a low temperature and superior lacquer-bonding property and appearance, comprises:(A) 40% to 75% by weight of at least one crystalline ethylene-propylene block copolymer in which the content of the polymerized ethylene is in the range of from 5% to 10% by weight, in which the polypropylene component has a fraction thereof insoluble in boiling n-heptane, in an amount of 97% or more, in which a fraction of the block copolymer soluble in p-xylene at room temperature, has an intrinsic viscosity of from 2.5 to 4 determined in decahydronaphthalene at a temperature of 135.degree. C. and which has a melt flow index of from 11 to 70;(B) 20% to 40% by weight of at least one amorphous ethylene-propylene copolymer having an intrinsic viscosity of from 1.0 to 2.0 determined in decahydronaphthalene at a temperature of 135.degree. C., and a Mooney viscosity ML.sub.

Abstract: A method of using 4-anilinoquinazoline derivatives of formula (I): ##STR1## (in which: R.sup.1 represents a hydrogen atom, a halogen, atom, a trifluoromethyl group or a nitro group;R.sup.2 represents a hydrogen atom, a C.sub.1 -C.sub.4 alkyl group, an alkoxy group or a halogen atom; andR.sup.3 represents a hydrogen atom or a C.sub.1 -C.sub.4 alkyl group)and pharmaceutically acceptable salts thereof are, provided that R.sup.1 does not represents a hydrogen atom or a chlorine atom in the 6- position when R.sup.2 and R.sup.3 both represent hydrogen atoms, as an analgesic and anti-inflammatory in the treatment of mammals.

Abstract: Apparatus for moving an injection cylinder of a molding machine between an injection position and a teeming position comprises a drive means, a link mechanism disposed between a pin on the side of the injection cylinder and a stationary pin secured to a lower platen so as to be expanded and collapsed by the drive means, a cam plate secured to oppose the side of the injection cylinder and provided with guide slot comprised of a longitudinal slot parallel with the axis of the injection cylinder when it is in the injection position and an inclined slot contiguous with the longitudinal slot, a first roller mounted on the side of the injection cylinder to be moved along the guide slot in accordance with the operation of the link mechanism, a guide member including a guide slot for moving the injection cylinder in the axial direction at the injection position, and a second roller positioned in the guide slot to act as a center of swinging of the injection cylinder.

Abstract: An inverted U-shaped frame is provided to straddle the injection molding machine, and a chain conveyor provided with spaced apart groups of L-shaped insert carriers is moved along the frame. An insert chute is provided for working side of the frame for loading cylindrical inserts on the carriers. An insert transfer device is provided on the other side of the frame for transferring the inserts from the chain conveyor to an insert holder which is swung between the insert transfer device and the metal mold. The holder holds the inserts in a pattern corresponding to the pattern of the inserts when they are disposed in the metal mold. The chain conveyor is moved intermittently at a predetermined feed pitch. An insert detector is provided near the chute and when the detector detects that an insert carrier is not loaded with an insert, the direction of movement is reversed to return the empty insert carrier to the chute to load an insert thereon.
