Abstract: ABSTRACT OF THE DISCLOSURE     A converter valve which is constructed from modular elements is disclosed.  Each of these modular elements comprises a group of thyristors arranged in side-by-side relationship and the drive means and circuit component group associated with such thyristor group.  A metallic shield surrounds the thyristor group and its associated drive means and a portion of its associated component group.  The shield, in turn, is supported within a metallic pressure tube which has both its ends closed off by bulkheads and is adapted to receive SF6 gas.  The aforesaid bulkheads may be separate connecting members which, in addition, may also be designed as nodal elements and mechanical support points.  The converter valve is constructed from a small number of the aforesaid modular elements, each element being replaceable without removing the gas from the entire valve.

Abstract: ABSTRACT            The invention concerns the packaging of commodities into vacuum-sealed packs formed from sheet plastics packaging material.          In accordance with this invention, the packaging material is formed from a two-layer laminate the inside layer of which has a much lower softening point than the outside layer.  The commodity is sandwiched between two sheets of the packaging material and is passed to a vacuum chamber in which it is sealed between the two sheets under reduced pressure.  Simultaneously the material is heated to a tem-perature at which the inner laminate softens, and when the chamber is aerated, the heated material collapses around the commodity and the inner layers fuse together around the margins to form a highly effective hermetic seal around the commodity.

Abstract: ABSTRACT OF THE DISCLOSURE       A suction line/capillary tube assembly which provides improved heat exchange between the cool gaseous  refrigerant conveyed by the suction line and the warm liquid re-frigerant conveyed by the capillary tube in a refrigeration system. The assembly is generally characterized by the capillary tube being within and in direct thermal contact with the suction line wall along a substantial length thereof. In a first specific embodiment, the capillary tube is soldered to the inside of the suction line, as opposed to merely being loosely passed therethrough. In a second specific embodiment, an aluminum suction line is fabricated with a internal extruded channel defined between a pair of ridges extending from the interior surface of the suction line. A copper capillary tube is snugly positi-oned in the channel and preferably the ridges are deformed toward each other so as to substantially surround the capillary tube. In a method of providing a suction line-capillary tube assembly as contemplated by the second speci-fic embodiment, the operation of deforming the ridges is accomplished by forcing a closure tool through the suction line. In a third specific embodiment, the capillary tube is snugly positioned within a longitudinal bore formed within the wall of the suction line.

Abstract: CLOSED LOOP METHOD AND APPARATUS FOR CUTTING                SHEET MATERIAL                 ABSTRACT OF THE DISCLOSURE            A method and apparatus for cutting sheet material utilizes a closed loop automatically controlled cutting machine having a reciprocating cutting blade as the cutting tool. Sheet material to be cut is spread in multiple plies to form a layup, and the cutting blade and the material are then moved relative to one another in cutting engagement along predefined lines of cut. During cutting a sensor detects a cutting parameter that is  affected by the interaction of the cutting blade and sheet material, and signals provided by the sensor are fed back in the closed loop automatic control mechanism to adjust or initiate further steps in the cutting operation. Such adjustment or ini-tiation alters the cutting machine operation for cutting condi-tions in real time in order to improve the overall performance of the machine.

Abstract: Abstract of the Disclosure The invention relates to a process for the preparation of a gamma globulin fraction suitable for intravenous administra-tion and being substantially free of anti-complementary activity.          The process involves extracting a paste or powder of Fraction II or II + III plasma protein or of a placental extraction contain-ing the Fraction with pyrogen-free water at a pH of from 4.9 to 6;  separating the extract thus obtained from solid material and treating the extract with polyethylene glycol in an amount of about 4% weight/volume;  separating the glycol-treated extract from solid material thus precipitated and subsequently treating with ethanol in an amount of from 4 to 12% weight/volume at temperatures of from -6 to 10°C;  separating solid material from the ethanol-treated extract thus obtained to yield a further extract;  and isolating the gamma globulin fraction from the further extract at temperatures of from -6 to 20°C and at a pH of from 7 to 8.2 by means of the addition of either polyethylene glycol in an amount of up to 12% weight/volume or of ethanol in an amount of up to 30% volume/volume, the gamma globulin fraction being substantially free of anti-complementary activity.

Abstract: ABSTRACT OF THE DISCLOSURE            A connector module for loadbreak operation having an insulating housing and a switch insert. The insert includes a container with a major portion of uniform diameter and a configuration such that the diameter does not increase from its outer end to its inner end, to permit the insert to be installed in the finishing housing. Inside the container is a snuffer-contact assembly which has a bore lined with an ablative material. A bore contact having a gas port is attached to a snuffer tube of the assembly and has fixed to it a piston adaptor for driving the snuffer-contact assembly toward the open end of the container tube in response to gas generated by arcing inside the bore. Resilient sliding contact means are fixed to the piston and press against the inside wall of the container tube to establish continuous electrical contact with it even while the piston is moving. A gas check valve member is resiliently seated against the inner side of the gas port and forms a gas retaining chamber the inner end of the container. Keyways in the piston ride over longi-tudinal keyribs formed in the wall of the container to prevent rotation of the piston in the container. A nose-piece is threaded into an expanded end of the container tube. Matching opposing grooves about the outer perimeter hold an open retaining ring which resiliently restrains the snuffer-contact assembly from axial movement in the container. An adapter ring rests against the inside should of the container tube where the diameter becomes expanded, to change the should configuration to a right angle. An O-ring gasket is fitted between the shoulder of the  adapter and the end of the nosepiece to provide a seal between the container and the snuffer-contact assembly.

Abstract: ABSTRACT OF THE DISCLOSURE         A pump for grinding materials contained in a liquid includes a comminutor located at the pump inlet to grind the material as it passes therethrough and into a pumping chamber. The pumping action is created by an impeller which communicates with the pumping chamber but which is located outside thereof to draw the material through the comminutor and into the chamber for radial discharge therefrom.          The comminutor includes a stationary annular ring in the inlet having a plurality of grinding teeth which form the internal diameter of the ring.  A cutting impeller is rotatable within the ring and has at least one blade which extends from one side of the impeller body axially outwardly beyond the ring to force the material between the teeth of the ring.  The other side of the impeller body is provided with means to provide additional shearing of the material and prevent clogging of the material between the teeth of the ring.

Abstract: Abstract.      To draw thin lines in a direction leading to a point it is necessary to locate the ruling edge of a common ruler or straight-edge on the fixed point each time such a thin line is drawn, and in the case of thick lines care has to be taken to put the ruling edge away from the fixed point by a distance equal to one-half the thickness of the line to be drawn.      When the fixed point is a comparatively long distance away necessitating the manipulation of a long and hence cumbersome straight-edge, the process becomes tedious and laborious and tends to lack in accuracy.      The invented instrument with its telescopic and rotating action combined with its aligning device is intended to facili-tate the accurate and quick drawing of such lines.
