Abstract: A method and system for controlling peak electrical demand placed on a source of electrical energy by a plurality of electrical loads that include at least one electrical load of lower priority than at least another of the loads. Demand for electrical energy by the loads connected to the source of electrical energy is sensed and, in response to the sensed demand exceeding a predetermined value the loads are selectively disconnected from the source. Normally, all the loads are connected to the source in the absence of a sensed excessive demand condition. Therefore, all demand control is lost in the event of failure of the controller. Accordingly, the system senses an abnormal operating condition of the controlling system of the type that renders the selective disconnecting means inoperative to disconnect the loads from the source. The electrical load of lower priority is then disconnected from the source for the duration of the sensed abnormal condition.

Abstract: A fluid pumping system includes a pump driven at a variable speed by a motor connected to the pump by a fluid cooled transducer. A regulator, connected to the transducer, controls, the speed of the pump responsive to an analog signal related in value to the flow rate of the pump and responsive to a control signal provided by a pump cycle controller. The pump cycle controller senses the level of a basin of fluid to be pumped and provides the control signal. The control signal is operative to start the pump when the fluid level reaches a predetermined starting level, to vary the pump speed responsive to changes in fluid levels higher than the starting level, and to run the pump at a minimum speed when the fluid level is between the starting level and a predetermined stopping level, lower than the starting level.

Abstract: An electrocardiograph electrode assembly is disclosed which includes a stretchable elastic strip having apertures in which electrodes are detachably mounted. The electrodes may be six in number and have a proportional spacing with respect to each other corresponding to the average proportional spacing of desired positions on the chest for electrocardiograph monitoring. A holder or retainer is provided for releasably engaging ends of the elastic strip to position and maintain the electrodes in contact with the chest of the patient. The holder may include a system of belts buckled to the strip and threaded through a base member positioned beneath the chest of the patient. Alternatively, weights may be attached to the ends of the strip to maintain the electrodes in contact with the patient's chest without placing a holder or retainer behind the patient.

Abstract: A water cooling tower and method which provides for both wet and dry cooling within the same vertical space and significantly reduces the discharge of water particles out of the tower. Water is deposited on one side of each of a plurality of trickler plates and flows downwardly under the influence of gravity substantially undisturbed as a low speed film. Air flows at low speed by natural draught in a substantially undisturbed path on the other side of each of the plates. Important dimensional ratios and construction details are disclosed.

Abstract: An improvement is disclosed in a process for the manufacture of metal halide particles containing at least one lanthanide metal halide in which the metal halide is melted and passed through a discharge conduit into an inert, quenching atmosphere. The improvement comprises adding a minor amount of hydrogen halide (the halide radical of the lanthanide metal halide and of the hydrogen halide being of the same halogen species) to the molten lanthanide metal halide to promote wetting of the molten lanthanide metal salt on the discharge conduit. The resulting particles show excellent uniformity of particle size and size distribution.

Abstract: The disclosure relates to a method of bending elongated materials such as pipe by applying a compressive primary bending force to the material at locations on either end of the portion of the material to be bent and locally stimulating bending of that portion of the material by the application of heat or a secondary bending force. The end portions of the materials are engaged by clamps, each clamp having an arm extending normal to the principle axis of the material. The compressive primary bend force is applied by exerting a force on locations on the arms displaced from the principal axis of the material, which force tends to draw the ends of the arms together.

Abstract: A compact, efficient grave digger is disclosed including a support frame and an excavation assembly which is carried by the support frame. The excavation assembly moves in a vertical direction beneath the support frame so that a grave may be excavated in a single downward pass of the excavation assembly. The grave digger includes a plurality of endless conveyors which loosen and remove the earth from beneath the excavation assembly. The support frame includes ground engaging wheels so that the grave digger may be selectively positioned at the grave site. Hydraulic jacks connect the excavation assembly with the support frame so that the excavation assembly may be raised and lowered with respect to the support frame. The excavation assembly may be adjusted so that graves of different lengths may be excavated.

Abstract: An improved apparatus for generating finely divided particulate gas bubbles in a liquid. The apparatus includes an outer body with a hollow shaft and a cavity defining means carried by the shaft. The shaft is apertured for communication with a gas supply and the cavity is apertured for communication with a liquid supply. The outer body also carried an inner body which includes a shaft and a plurality of vanes. The shaft of the inner body is journaled for rotation within the hollow shaft of the outer body.

Abstract: A heat pipe element comprising an outer pipe member and an inner tubular member incorporated in the inner circumference of the outer pipe member with a capillary space defined between the two members, which inner tubular member is formed by winding in a spiral shape from a web of sheet material with a narrow continuous space between the adjacent surfaces of thus-shaped inner member so that a capillary action may occur in the narrow space. A multiplicity of fine recesses extending longitudinally of the inner and/or outer members may be formed in the inner and/or outer circumference of the inner member and/or in the inner circumference of the outer member.

Abstract: A fluid pump dispenser includes a dispenser trigger which may be located in pivotable engagement with the dispenser housing and pump piston after shipment. The initial actuation of the trigger moves the pump piston and a container conduit, engaged thereto, to open a container vent shipping seal provided by mating surfaces on the conduit and the container cap. Fluid carried from the container by the conduit enters the pump chamber through a central orifice in the piston. A flexible member located on the piston functions as an inlet check valve for the conduit and as a piston ring. The fluid dispenser also includes a nozzle structure having a flexible member which functions as an outlet check valve and O-ring seal, and which cooperates with a threaded nozzle cap to vary the discharge pattern of the dispenser responsive to twisting adjustment of the cap.
