Abstract: ABSTRACT OF THE DISCLOSURE An oxygen ion conductive solid electrolyte elec-trochemical cell is employed to pump oxygen for combustible reaction with fuel constituents of a combustibles gas en-vironment which diffuse through an aperture of a housing. The housing in combination with the solid electrolyte elec-trochemical cell forms an internal chamber.  The EMF estab-lished across the electrodes of the solid electrolyte elec-trochemical cell pumps sufficient oxygen for complete com-bustion with the fuel diffusing through the aperture into the internal chamber.  The resulting current of the solid electrolyte electrochemical is indicative of the rate of diffusion of the fuel or combustibles constituent through the aperture.  The rate of diffusion is proportional to the fuel or combustibles content of the combustibles gas en-vironment.  An EMF measuring circuit connected to an auxiliary pair of electrodes associated with the solid electrolyte electrochemical cell is used to sense the condition wherein the atmosphere within the internal chamber changes between a reducing atmosphere and an oxidizing atmosphere.  This EMF indication can be used to identify a predetermined level of pumping electrical potential at which variations in the solid electrolyte electrochemical cell current is indicative of the rate of diffusion of the fuel or combustibles consti-tuent through the aperture.

Abstract: AUTOMATED POST BURN STATION            Abstract of the Disclosure An automated apparatus for sequentially forming integrally fused battery terminals on a plurality of storage batteries is des-cribed wherein a head means having a mold means adjustably mounted thereon is automatically movable with respect to a vertical axis, and has slidably mounted thereon a burning means for automatically producing a variable-intensity flame for melting said battery elements to form said integrally fused battery terminal during a vertical stroke thereof.   An automated post burn station is further described having a conveyor means for advancing batteries sequen-tially to said burning station and for aligning said batteries with respect to said station for the above described fusing process.   A plurality of novel sensors incorporated into the automated post burn station facilitates the rapid, automatic processing of batteries, while providing a high degree of safety and reliability.          In alternate embodiments of the present invention, members may be welded together by indirect application of heat, as for welding internal battery posts for connecting groups of plates or terminal posts electrically, through the use of a plurality of heated elements simultaneously engaging posts to be welded together, and wherein the configuration of molten metal is con-trolled as the weld cools, by the use of a template.   The elements are heated, preferably by application of open flame through a plurality of mixing systems for the fuel, with one system being provided for each element.     In both the indirect and direct heat applications relating to welding mechanisms for forming terminal posts for batteries, a novel molding means is described comprising a structural member composed of aluminum or other high heat transfer material, which is adapted to interchangeably engage an aluminum mold member which mates with the structural housing and which actually forms the voids in which the melting and casting processes take place.   The mold members, which are also composed of aluminum or other high heat transfer material, are provided with a novel mold coating consisting essentially of aluminum oxide formed through an anodization process.   This novel mold coating is disposed on the surfaces of the mold members which define the molding voids, and act as a thermal barrier to cause momentary delay of heat transfer from the melted terminal posts to the remainder of the mold members and their associated structural housings.   This novel mold coating is described as having superior release characteristics, while facilitating the formation of high quality battery terminal posts.

Abstract: C-2893                                D-2,698 DIESEL ENGINE GLOW PLUG ENERGIZATION CONTROL DEVICE            Abstract of the Disclosure A glow plug or plugs for a Diesel engine is energized directly or indirectly through the normally closed contacts of a thermally operated switch, preferably a bimetal switch, in thermal communication with the engine and a local electric heater that is energized by the same source as the glow plug and controlled in unison with the glow plug.  The bimetal switch is arranged to switch off at a temperature of the order of 80°C which, at an initial engine temperature of the order of -18°C, permits the glow plug to heat to the order of 900°C.          The hysteresis in the bimetal switch is arranged to close the switch when the glow plug has cooled to the order of 810°C, thus the glow plug is cycled between the order of 800°C and 900°C.  It has been found that the glow plug temperature rise at elevated temperatures is substantially less than propor-tional to heat input.  As a consequence, the effect of lower engine temperature is to produce increased glow plug  tempera-ture less than proportional to the bimetal temperature rise over engine temperature prior to switch opening, and the effect of increased engine temperature is to lower the glow plug temperature less than in proportion to the lesser bimetal temperature rise over engine temperature.  With proper selec-tion of the bimetal switch characteristics, the variation of glow plug temperature with engine temperature substantially matches the engine requirement for ease of start.  Further, the glow plugs are initially heated at a very rapid rate and reach temperatures suitable for engine crank more quickly than with conventional, continuous, glow plug energization.

Abstract: ABSTRACT OF THE DISCLOSURE         A computer terminal employs a CRT display, a micro-processor, and a random access memory which both stores character codes for information to be displayed on the CRT screen and serves as working storage for the processor.  To generate a line of text across the display the processor loads a memory address counter with the address of a memory location containing the code for the first character of the line.  The counter is incremented in timed relation to the generation of the display and sequentially outputs consecutive memory addresses in which the consecutive character codes forming the line are stored.          During the generation of the line the activity of the processor is inhibited.  Following generation of the line the processor regains access to the RAM and tends to I/O duties or modifies the display memory contents until it passes control of the RAM back to the address counter for generation of another line of display.

Abstract: METHOD OF MAKING A HELICALLY CORRUGATED TUBE     ABSTRACT OF THE DISCLOSURE         A helically corrugated tube with improved heat transfer characteristics is made by twisting a deformable tube of circular cross section and at the same time moving the ends of the tube axially relative to one another.  First the tube is twisted while the axial ends of the tube are moved relatively toward each other to cause helical corrugations to develop progressively along the tube.  When the corrugations have been formed, the twisting and moving of the ends of the tube are terminated and then the tube is reverse twisted and axially stretched to a length greater than the length of the original tube.  The resulting tube is corrugated and longer than the original tube, and has improved heat transfer and fluid flow characteristics.

Abstract: ABSTRACT OF DISCLOSURE     An improved locknut has an axially extending central opening with standard thread convolutions which freely engage an externally threaded member and lock thread convolutions which interfere with the threads on the externally threaded member to provide a locking action. The lock thread convolutions have an axial extent which is less than half of the total axial extent of the internal threads on the nut.  The lock thread convolutions are formed by making a plurality of indentations in the nut body.  Each of these indentations is defined by a continuously curving surface which forms part of a cylindrical plane.  Each indentation has continuously curving edges which intersect at a pair of peaks at opposite ends of the indentation.  Each indentation also has a height which is less than one-third of the height of a wrenching flat and a width which is less than one-third of the width of a wrenching flat.  This enables the number of free running standard thread convolutions on the inside of the nut to be maximized and minimizes galling between the locking thread convolutions and the external thread convolutions.
