Abstract: A convenient method for the quantitative determination of a DNA polymerase includes contacting an aqueous test specimen suspected of containing the enzyme with the following: a single-stranded DNA template present in a concentration of at least 10<-><8> molar bases, a DNA primer complementary to the template, a source of a metal polymerase cofactor, sufficient deoxyribonucleoside triphosphates to synthesize double-stranded DNA in the presence of the polymerase, and a colorimetric or fluorescent dye which is capable of providing a detectable signal when a primed single-stranded nucleic acid is converted to double-stranded DNA by the polymerase. The rate of signal generation is then measured and can be correlated with the level of DNA polymerase in the specimen using graphical or mathematical means. The results of this method are precise, having a covariance of less than 10%. A test kit includes the reagents needed for carrying out this method. <IMAGE>

Abstract: Entomopathogenic nematodes are cultured in a culture vessel comprising a tray (10) with side walls (12) and an overlapping lid (11), also with side walls (13). A gasket (14) of polyether polyurethane foam is positioned around the inside edge of the lid. In the preferred vessel, stop members (16), mounted on the inside faces of the walls of the tray, prevent forced movement of the lid towards the tray when flanges (15) on the lid bear against the stop members. Such an arrangement enables the culture vessels to be stacked on each other without over-compression of the foam gasket. A method of rearing juvenile (J3 stage) nematodes using such a culture vessel, which involves inoculating the contents of the culture vessel with monoxenic suspension of nematodes, is also disclosed. A method and apparatus for harvesting nematodes, a vessel for incubating nematodes for use as an inoculum, and a method of separating J3 stage and adult nematodes are also described. The culture vessel can also be used to culture fungi, protozoa, bacteria and tissue cultures.

Abstract: A first phase locked loop (12) generates a first timing signal (on 17) at a first horizontal synchronizing frequency (1fH) corresponding to a horizontal synchronizing component (on 13) in a video signal (on 11). A converter circuit (56) derives from the first timing signal (on 17) a second timing signal (on 61), having a second frequency (2fH) at a multiple of the first frequency and subject to a variation in frequency at a rate corresponding to the first frequency. A second phase locked loop (62) receives the second timing signal (on 61), which can be asymmetric within the period of the first timing signal (on 17), and a feedback signal (on 73) in accordance with the second frequency, and includes a controllable oscillator (66) for generating a smooth horizontal synchronizing signal (on 67) at the second frequency. The second phase locked loop has a characteristic loop response, determined by a low pass filter (63), preventing the voltage controlled oscillator (66) from changing frequency as fast as the rate of variation of the second timing signal (on 61). This drives the error signal for the controllable oscillator (66) toward an average value, resulting in a corrected, symmetric synchronizing signal at the second frequency. A horizontal output deflection stage (68) may be coupled to the second phase locked loop (62) for synchronized horizontal scanning in accordance with the second frequency. No additional signal processing circuitry is needed to correct the symmetry of the first timing signal generated by the first phase locked loop or the symmetry of the second timing signal derived by the converter. <IMAGE>

Abstract: A zero-pressure accumulating conveyor including a bed defined by rotatable rollers mounted in parallel sidewalls and powered by an endless drive chain. Pneumatic actuators lift the drive chain into engagement with the rollers to empower same. Sensor rollers divide the bed into distinct zones. Sensor rollers are retained in operative position relative to the conveyor bed by unique sensor brackets. A primary sensor roller bracket includes a bore with a piston movable there within; the cooperating secondary sensor roller bracket is spring biased in a first direction. Valves, and pneumatic circuitry controlled by such valves, extend along the length of the conveyor. Such valves are operated by the primary sensor roller brackets to regulate the flow of air pressure into the bores of the brackets and into the actuators. The actuators, when the pressure therein is bled-off, allow the chain in a particular zone to drop out of contact with the rotatable rollers. When the bore in the primary sensor roller bracket is pressurized, the bracket moves in an arc that forces the sensor roller below the plane of the conveyor. In such position, the sensor roller is not actuated as items travel thereover, and the life of the accumulating conveyor is significantly extended.

Abstract: Source nodes (103(a)) in a network (101) for translating names into network addresses receive names (N109(i)) and have name caches (111) for translating the names; destination nodes (103(b)) have local name tables (114) containing correspondences between names and the network addresses (107(i)) served by the destination node. There is further a name server (119) accessible to the nodes which contains current correspondences between names and network addresses. A name is translated by first presenting it to the name cache (111) in a source node; if there is no entry for the name in the cache, name cache maintenance code in the source node obtains information about the name from the name server (119); once there is an entry, the name is translated and a call set up message containing the name and the network address is sent to the destination node (103(b)), which checks whether the name and network address are its local name table (114). If they are, the destination node returns a call complete message to the source node. Otherwise, it returns an unknown destination message to the source node. The name cache maintenance code responds to the unknown destination message by invalidating the cache entry and obtaining the correct information from the name server (119). <IMAGE>

Abstract: A novel method enabling stretch blow molding in a temperature range preferable for polyethylene, capable of releasing at a surface temperature suited to both releasing of a preform and subsequent stretch blow molding, by disconnecting the core die and the preform in advance by the use of pressure of gas. This is for injection molding a predetermined preform by filling an injection mold with molten polyethylene, releasing the preform from the cavity die and core die of the injection mold while a mouth portion of the preform is held by the lip die, and transferring the preform into a blow die to stretch blow mold into a hollow molded product of thin wall. Gas is forcedly entered into the boundary of the core die and the preform, before releasing the preform from the injection mold, to isolate the inside wall of the preform from the core die. Releasing is effected while the inside of the preform is not completely cooled and is still at high temperature, and in a temperature range in which the surface temperature of the preform right after releasing is 80 to 90 deg. C. The step of stretch blow molding is performed within the time interval before the surface temperature of the preform which is elevated by the internal heat of the preform reaches 120 deg. C.
