Abstract: An automated telephone calling system receives a group of telephone numbers from a host computer. For each telephone number there is a corresponding record of unique information. The host computer is connected to drive a plurality of operator display terminals. Each number is automatically called and equipment provides detection of rings, busy signals, recordings and voice answers. When a party answers a call, the called line is connected to a non-busy one of a group of operations. At the same time a report is sent from a central controller to the host computer reporting which number has been successfully called and which operator has been selected for the audio connection. The host computer then calls up the record for the called number and transmits at least a portion of the record to the display for the selected operator. The operator is thus provided with an audio connection to the called party as well as a screen display of relevant information for that party.

Abstract: A luminous gas filled tube system has a direct current source, a pulse transformer secondary winding, the emitter-collector path of a transistor, and the gas filled tube connected in series. The voltage of the source is below the ionization potential of the gas in the tube but adequate to supply current when the gas is ionized. A pulse source is connected for selectively generating a high voltage pulse in the winding of magnitude such that, when added to the voltage from the source, the ionization potential of the gas is exceeded. A starter circuit is provided for selectively actuating the pulse source to initiate ionization of the gas in the tube. A variable resistor is provided for selecting the amount of current flowing in the series circuit at any level below a maximum rating of the transistor.

Abstract: A door lock (10) includes a strike case (18) adapted to receive a dead bolt (14). A rotatable keeper (20) is rotatable between an open and closed position for opening and closing the strike case (18). An abutment member (30) is connected to the rotatable keeper (20) and is selectively rotatable with the rotatable keeper (20). A sensing arm (34) is connected to the strike case (18) for sensing the presence of the dead bolt (14) in the strike case (18). The sensing arm (34) selectively disengages the abutment member (30) for allowing the abutment member (30) to rotate with the rotatable keeper (20) if the dead bolt (14) is detected within the strike case (18).

Abstract: A circular temperature gauge includes tubing which encloses a temperature sensor and a housing which encloses a needle connected to the sensor and a dial connected to the housing. The housing is secured with respect to the tubing such that the housing can be rotated to calibrate the indicator needle with respect to the dial. A slip bezel is mounted on the periphery of the circular housing. The force required to rotate the bezel with respect to the housing is less than the force required to rotate the housing with respect to the tubing. This prevents a worker who is in the process of installing the gauge from inadvertently rotating the housing with respect to the tubing and substantially miscalibrating the gauge.

Abstract: An apparatus (10) for concentrating the level of a proppant in a slurry under pressure includes a cyclone chamber (22) having a reduced diameter end with an exhaust outlet (40) therein. A slurry and proppant mixture is introduced under pressure into the chamber at an inlet (120) substantially along a path tangential to the side wall of the chamber. Flow of fluid into the cyclone chamber causes the slurry and proppant mixture to follow a spiraled path toward the exhaust outlet such that the heavier constituents in the mixture move near the inside wall of the chamber. A reflux tube (140) is positioned within the chamber and permits the removal of fluid from the low proppant concentration area of the fluid chamber and directs the fluid across a choke (90, 90') and to a deenergizer (94, 94'). The deenergizer includes a housing having an inner longitudinal tube (184) with an inlet (180) for receiving fluid from the cyclone chamber and a closed end opposite the inlet.

Abstract: A process for the alkylation of aromatic hydrocarbons in a reaction zone containing a crystalline silica polymorph silicalite catalyst. The feed stock to the reaction zone comprises an alkylating agent and an aromatic substrate contains sulfur in an amount, greater than 2 ppm, which heretofore has considered to be unacceptable to zeolite catalysts. A steam cofeed may also be applied to the reaction zone in an amount sufficient to reduce the deposition of coke on the catalyst due to the presence of sulfur. Sulfur may be present as a contaminant in the aromatic substrate or the alkylating agent.

Abstract: A knee ligament testing device (10) is disclosed for use in testing the ACL ligament of the knee. The device includes a force application arm (12) and reference arm (18) which are hinged at a pivot joint (20). A predetermined maximum force can be applied to the force application arm (12) by exerting force on a torque limiter (26) inserted in an aperture (38) in the force application arm (12). The torque limiter (26) insures that the identical force will be applied on a leg for every test to insure reproducibility and prevents the application of excessive force to the leg. Displacement of the tibia relative to the femur is sensed by movement of an inner tube (56) relative to an outer tube (54) which is translated into rotational movement of an input shaft through potentiometer (66). The change in resistance in the potentiometer (66) is analyzed and converted to a linear measurement which is displayed on a display (72).
