Abstract: A power burner adaptable for use in conjunction with a wood burning stove employs a blower to produce a forced flow of air and a fuel valve which provides selective fuel communication with a fuel nozzle. Forced air and fuel is mixed in the nozzle and propelled through the nozzle outlet along a generally unidirectional exit path. A target is spaced from the nozzle outlet and interposed in the exit path. A heating assembly which is spaced from the target heats the target to a temperature sufficient to ignite the mixture traversing the exit path. A blast tube surrounds the target and forms an axially extending passageway which functions as a combustion chamber and a passageway for propelling the combusted fuel through an outlet opening of the blast tube. The burner is automatically controlled by an electronic controller.

An impact absorbing frame is provided around the access opening at the front of the outer housing. The outer housing is mounted, by means of integral hubs, from a support by means of a yoke. The hubs are relatively rotatable with respect to the yoke to permit the outer housing to be positioned in a desired angular orientation.

Abstract: A tear-open strip is severed from a band of material having a width equal to the desired length of the tear-open strip by cooperation between a stationary knife-edge defining member and a pivotal knife-edge defining member. The knife edges form chords of a hyperboloid of revolution and are inclined relative to one another. The pivotal knive-edge defining member is provided with suction ports adjacent to the cutting edge whereby a severed strip may be transported by the knife to an intermittently moving sheet of packaging material to which the strip is subsequently bonded.

Abstract: Cigarettes are transferred by a rotatable device from the exit ends of guide channels in a receiving funnel to a device which arranges the cigarettes in layers for subsequent formation of cigarette blocks to be wrapped. The rotatable transfer device consists of a drum provided with spaced groups of cigarette receiving grooves on its periphery, the receiving funnel and the layer-forming device being generally oppositely situated with respect to the drum and being vertically separated whereby gravity feed to and discharge from the drum may be effected. A mechanism for insuring that cigarettes will be fed from the receiving means to all of the grooves of each group on the drum at the same time is associated with the drum.

Abstract: A container suitable for storing compact discs conveyed in motor vehicles comprises a housing from which the stored discs can be ejected by means of a single transporter associated with a plurality of discs. The transporter may be selectively coupled to only one disc holder. The transporter is preferably a slider member which is arranged to slide in the housing, can be locked in the housing against a spring bias and unlocked manually, and has a front wall to cover the open front of the housing when the slider member is inserted. The selector mechanism and the unlocking operation can be actuated from the outside of this front wall.

Abstract: A container carrier adapted for receiving a plurality of containers for transportation of same is assembled from a unitary sheet of plastic. The containers are captured between retainer edges of transverse members forming a supporting web at the lower portion of the carrier. The panels function to clamp the containers in position upon seating of the containers in the carrier. In a filled configuration the carrier is supportable on a plurality of legs which are configured to cooperate with the transverse members for retainably capturing the containers.

Abstract: A rotary fuel injection pump with a rotor having pumping plungers reciprocated for supplying high pressure charges of fuel for fuel injection and a spill control mechanism having one or two rotary spill valves mounted on the rotor and rotated in unison with the rotor and in synchronism with the reciprocable movement of the pumping plungers for spill control of the high pressure charges of fuel. The spill timing is adjustable by the spill control mechanism at the beginning and/or end of the fuel injection event.

Abstract: A multi-stage steel wire drawing machine has, in each stage, two dies and a single drive motor for drawing the wire through the two dies. In a preferred arrangement the dies are mounted side-by-side and an idler wheel used to define part of the wire path between the dies in the stage and a coaxial driven wheel is used to draw the wire through both dies in the stage and to define part of the wire path leading to the next stage. Dry wire lubrication before die entry and water cooling after passage through the dies are disclosed.

Abstract: An automatic compactor enhancement reduces the volume of compactable low-level radioactive wastes and transfers the reduced wastes to a nearby waste compactor. The wastes are shredded by a primary shredder assembly and a secondary shredder assembly. The system employs a pressure-controlled enclosure means to house the shredder assemblies and to control the release of wastes to the environment. A number of safety features are integrated into the system to enhance the operational safety of the system.

Abstract: A warning device is responsive to the failure of an electric power supply for activation to a warning mode. The warning device includes an arm pivotally mounted to a frame member and latched by an electromagnet in a non-warning mode. In the non-warning mode, a collapsible warning sign carrier is enclosed within an enclosure formed by the frame and the arm. When the supply of power is interrupted, the electromagnet releases the arm so that the arm pivots to a warning position.

Abstract: A predetermined amount of erosion of a material conveying conduit or the like is detected by inserting a probe in the conduit wall, from the side opposite to that subjected to the wear, to a predetermined depth. The probe comprises an insulated conductor which is in electrical contact, at the base of the blind hole, with the conduit. Wear of the conduit down to the level of the probe may be determined by periodic continuity measurements, a lack of continuity indicating that the inserted end of the probe has been exposed.
