Abstract: Abstract of the Disclosure A low stress stem connection structure (77) for connecting the rotatable stem (43) and the gate member (33) of a non-rising stem type gate valve (1). The stem (43) has an externally threaded end section (47) and the gate member (33) has an externally threaded extension (79) with a longitudinal bore (83) in which the end section (47) of the stem (43) is received. A stem nut (87) is threadably received on the end (47) of the stem (43) and engages the gate member extension (79) to reciprocally move the gate member (33) in response to rotation of the stem (43). The gate member (33) may move relative to the longitudinal axis of the stem (43) in the direction of flow of a fluid through the gate valve (1). A gate nut (97) is threadably received on the gate member extension (79) to hold the stem nut (87) in position on the stem (433 and limit movement of the gate member (33). The structure facilitates movement of the gate member (33) to open and close the gate valve (1) even though the gate member (38) is subjected to high fluid pressures.

Abstract: ABSTRACT OF THE DISCLOSURE         A fluorescent lamp having a multi-U-bent tubular envelope of convoluted  configuration  is  combined  with circuit means, a translucent protective cover and a base module to provide an efficient lamp unit of high bright-ness and long life that is compact enough to be used as a replacement for incandescent lamps in fixtures designed for  residential  and  commercial  lighting  installations.          Various spatial arrangements for including the ballast and starter components of the energizing circuit as integral parts  of the compact  lamp unit,  despite the stringent space limitations,  and also venting the cover and base module to provide  convection cooling of the convoluted fluorescent lamp and the other electrical components are also disclosed.  Tubulations provided on U-bent portions of the lamp envelope serve  as phosphor-drainage means during lamp manufacture and are subsequently tipped off to form mercury-condensation  chambers  within  the  finished lamp that regulate the mercury-vapor pressure during lamp operation.  The vapor-pressure regulating tubulations are so located relative to the vent openings in the lamp unit that they are exposed in the cool air which circulates through the lamp unit when the latter is energized and in use.

Abstract: ABSTRACT OF THE DISCLOSURE     A clock generator for producing a two phase output comprises a bistable circuit having two stages. The output of each stage is cross coupled to the input of the other and each cross coupling path includes a high-resistance transfer gate.  Each transfer gate forms part of an RC delay element which is so arranged that at a transition of clock signals the output of one of the stages completes its transition substantially at the same time as the output of the other stage begins its transition.  This results in non-overlapping outputs from the generator.

Abstract: ABSTRACT OF THE DISCLOSURE         A device for radiographically inspecting the girth weld seam on a double jointed pipe including a cart on which the pipe is mounted, for transporting the pipe longitudinal-ly to a location where it surrounds a radiation source mounted on one end of a cantilevered boom.  A radiation de-tection unit that produces a visible image of radiation penetrating through the pipe is disposed on the outside of the pipe in alignment with the radiation source.  When the girth weld on the pipe is brought into registry with the radiation source by the cart, rollers on the cart are actua-ted to rotate the pipe about its longitudinal axis, thereby enabling the entire periphery of the girth weld to be in-spected.  The video image of the girth weld can be observed on a video monitor, and recorded by means of a video cas-sette recorder and a facsimile unit.  In addition to the girth weld image, appropriate instructions relating to re-pairs to be performed on the pipe can be included in the recordings.  A spray marker located adjacent the radiation detection unit enables an operator to precisely mark the location of detected flaws on the pipe, to facilitate subse-quent repairs in accordance with the instructions on the recorded medium.

Abstract: ABSTRACT OF THE DISCLOSURE    A circuit for driving a power transistor that forms a part of an inverter circuit used in motor control in which the circuit is switched at high voltages.  The motor drive circuit isolates and amplifies a control signal so as to operate the power switching transistors.  The base drive circuit employs two characteristics of power transistors to derive maximum protection and maximum performance simultaneously.  This control is accomplished by sensing both the collector-to-emitter voltage of the power transistor as well as the base-to-emitter voltage thereof.  In an alternate embodiment described herein, a feedback circuit is also provided sensitive to collector-to-emitter voltage for shortening the try-time associated with the power transistor.

Abstract: ABSTRACT OF THE DISCLOSURE      A data processor having a plurality of processing elements and a mechanism to receive strings of object code, form them into higher level tasks and to determine sequences of such tasks which are logically independent so that they may be separately and concurrently executed by the plurality of processing elements.  The mechanism makes all memory accesses required by the various tasks and stores those tasks along with corresponding pointers or references to local memory in which the various data items have now been stored. The mechanism employs a symbol translation table in which the tasks are stored in forms of queues along with symbols representing the various references or pointers to local memory.  In this manner, various data items can be assigned different symbols or symbolic names for use with different tasks thus further limiting dependency between various tasks and controlling data changes.
