Abstract: ABSTRACT OF THE DISCLOSURE     The disclosure describes an apparatus for the electropho-resis of multiple agarose slab gels.  It comprises a train of at least three elongated box-like containers such as twelve, which are set consecutively in substantially parallel fashion at a variable distance from one another, each container to contain a running buffer.   The first and last containers are each provided with an electrode for connection to a single suitable power supply.   A plurality of horizontal plates, each to contain a slab gel, are disposed in bridging fashion over adjacent spaced apart containers, to cover gaps between all the containers.  The apparatus comprises first means capable of establishing capillary contact between one end of the slab gel and the running buffer which is present in a given container, and second means capable of establishing capillary contact between the other end of the slab gel and the running buffer which is present in the next container.          A method for the separation of components from a mixture of molecules of mixed molecular weights, wherein a solution of said molecules is added to wells formed in a horizontal slab gel and the gel is thereafter treated by the above electro-phoresis to produce localized bands each being characteristic of a specific molecular weight, is also disclosed.

Abstract: Abstract of the Disclosure A device for dispensing molten thermoplastic material in which a solid block of thermoplastic material is pressed through a sleeve and into a heated melting chamber from which the molten thermoplastic material is discharged through a nozzle.  A cooling assembly can be disposed between the melting chamber and the nozzle to provide means for substantially cooling the molten thermoplastic material (e.g., by about 19 Centegrade degrees) which can be advantageous where the temperature of molten thermoplastic material in the melting chamber can become so high that it will damage certain substrates on which the molten material will be dispensed.

Abstract: Title SCROLL MACHINE USING DISCHARGE PRESSURE FOR      AXIAL SEALING                         Inventors James C. Tischer Robert E. Utter Abstract A scroll compressor in which a fluid compressed by the ma-chine is applied to one side of an orbiting scroll plate to provide an axial sealing force directed toward an opposing stationary scroll plate.  Intermeshed involute wrap elements on facing surfaces of the two scroll plates define pockets in which the fluid is compressed as a motor drives one of the plates in an orbital motion relative to the other.  Both the motor and scroll plates are enclosed in a hermetic shell.  The volume enclosed by the shell is divided by the driven scroll plate and an internal supporting frame into one part that is at suction pressure and another part at discharge pressure.  A seal extending from the frame abuts the back side of the driven scroll plate and defines the relative areas of that plate which are exposed to suction and discharge pressure.  The net force resulting from these pressures acts on the orbiting plate, biasing it toward the stationary plate to provide axial sealing between the involute wrap elements and the scroll plates.

Abstract: ABSTRACT            PILOT OPERATED SUPPLY AND WASTE CONTROL VALVE      Supply and waste diaphragm valves communicate with each of two load ports 26, 28 and all valves are controlled by a pilot valve 78 and a pressure reversing valve 74.  In one form, the pilot valve 356 has a rocker arm valve member 366.  The pilot valve 78 applies high or low fluid pressure to control chambers 48, 64 and the control faces of two main diaphragms 40, 46, and it applies the same pressure to a diaphragm 90 which actuates the reversing valve 74.  The pressure reversing valve 74 applies a reverse pressure to the control chambers 56, 62 and the control faces of the other two main diaphragms 42, 44.  The pressure reversing valve 74 is a pressure actuated, supply and waste type valve in which the pressure applied by the pilot valve actuates a pressure driven element.  The pressure driven element may be a diaphragm 90 or bellows 100. A higher control pressure is obtained with a ram nozzle 66 directed into the supply fluid at a point of maximum flow velocity.  Seat loading of the diaphragms may be created by positioning valve seats 260, 266 beyond the free positions of the diaphragms 252, 270.
