Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to a method of manufactur-ing integral melt conveying nozzle probes for injection molding. The generic term nozzle probe is used herein to include both nozzles through which the melt flows centrally and probes which it flows along the outside of.      The method includes forming a stainless steel outer member to receive an electrical heater member therein with a longitudinal space therein.  A long thin thermo-couple sleeve have a closed forward end is located in the space, which is then sealed against leakage by applying a nickel brazing paste to the joints and brazing them in a vacuum furnace.  Copper  is then cast into the space in a vacuum furnace to provide a metallurgical bond between the highly conductive copper and the heating element, the thermocouple sleeve and the other parts of the nozzle probe.  After casting, a long thin drill is inserted into the sleeve to drill through the closed forward end and a predetermined distance into the copper.  The use of the sleeve avoids the problem of the drill wondering slightly off line and ruining the whole unit.  A thermocouple can be removably inserted into the bore with its head precisely located in the highly conductive material adjacent the forward end of the nozzle probe to provide an accurate and reliable measurement of temperature in this critical area.

Abstract: ABSTRACT OF THE DISCLOSURE Lead-type ballast apparatus operable to program and control the operating performance of a high-intensity-discharge sodium lamp.  The basic lead-type ballast com-prises a current-limiting high-reactance transformer hav-ing a capacitor connected between the transformer output terminals and the lamp to be operated.  A pulse-generating means is normally associated with the transformer secon-dary and is operable to generate high-voltage pulses when the apparatus is energized which are applied through the capacitor to initiate a discharge within the lamp.  There is also provided an additional inductor which is connected in circuit in one of (1) a parallel connection across the capacitor and  (2)  a connection across  the  transformer secondary.  An "open or closed" switch connects in circuit with the additional inductor.  A sensing and programming means operates to sense at least one lamp operating param-eter to control the proportion of time the switch is open and closed,  in order to vary the current input to the lamp.  Any of a variety of lamp operating parameters may be sensed in order to control any of a plurality of de-sired lamp operating parameters.

Abstract: ABSTRACT        The present invention provides a chain having links each of which comprises opposed C-shaped end portions con-nected by joining limb portions.  The links are constructed such that when viewed normal to the plane of a link, each link presents a waisted configuration at the joining limb portions.    Alternatively,  the  outer peripheral parts  of the joining limb portions can have bevelled edges so that the link presents a waisted or scalloped form when viewed at 40°  to 90°  to the plane of the link.   A central stud is  preferably provided  in  each  link.   By arranging the chain  links  to  have  the  above  configuration,  the stress loading of the chain can be considerably improved,  part-icularly for  the  case where the chain is passing around a wildcat, fairlead, hawsepipe or other curving chain guide means.

Abstract: Abstract of the Invention A utility data gathering system is disclosed as comprising a register including a series of index members coupled to a meter mechanism.  Each index member includes a plurality of contacts and a switch arm moveable with its index member.  The meter mechanism is responsive to utility consumption for moving the index members to positions indicative of the utility consumed, whereby each switch arm completes in normal operation a circuit with just one of its plurality of contacts dependent upon the position of its index member.  A digital computer is programmed for performing first and second scans of each contact of each index member to obtain corresponding first and second sets of data indicative of a completed circuit through the switch arm and contacts of each index member. The completed circuit data obtained from each of the first and second scans are compared and if the circuit data of The first and second scans are different,  an alarm manifestation is generated.

Abstract: Abstract A disconnect switch is provided for a metal-clad, pressurized-gas insulated, high-voltage switch gear installation.          The disconnect switch includes:  first and second contact assemblies which have a common longitudinal axis and are switch-able between an open position and a closed position.  An isolating tube is positioned inside one of the first contact assemblies and is movable therein along the axis during a switching operation between an open position at which the contact element is completely within the said one contact assembly and a closed position at which the said contact element engages the other contact assembly.  First and second resistors are positioned within the isolating tube and are movable along the axis inside the isolating tube during switching toward and from the other of the contact assemblies.  The disconnect switch for a metal-clad, pressurized-gas insulated, high-voltage switch gear installation discourages generating of high frequency oscillations and arcing to the metal of the encapsulation during switching.  The disconnect switch uses two resistors of equal size which move inside an isolating tube to make electrical contact prior to the main contacts and to break electrical contact after the main contacts.          In this manner, the arc is encouraged to exist between the two resistors inside the isolating tube.
