Abstract: Abstract of the Disclosure A die for the extrusion of a tube of plastic polymer consists of at least two coaxially mounted die parts forming one or more annular die gaps between them from which the tube is extruded.         The die parts have two respective axial cylindrical surfaces.          There is provided between these surfaces an annular member of material of higher coefficient of expansion than the material from which the die parts are made.  As the die becomes heated this annular member also becomes heated and its additional expansion causes its outside diameter to expand and its inside diameter to contract into forcible engagement with the surfaces thereby stablizing the radial gap between the die lips.

Abstract: ABSTRACT OF THE DISCLOSURE         A portable heating unit is provided herein comprising a heater and a low velocity blower, an elongated lightweight collapsible flexible, heat-carrying duct, and an intermediate high velocity intake fan unit for mixing the low velocity heated air from the portable heater with ambient air and for introducing the mixed air streams into the inlet end of the flexible duct.  The intake fan unit includes a venturi for assuring ade-quate mixing of the air within the elongated flexible collapsible tube to provide a high velocity flow of air at a substantially constant tempera-ture level along the length of the flexible tube.  The tube is provided with a plurality of openings arranged in spaced intervals to eject high velocity jets of heated air at locations where they may be used most effec-tively.  The unit is designed to be positioned upon the ground and the remote end is sealed and preferably staked or otherwise held to the ground to prevent undue movement.  The diameter of the elongated flexible tube is selected to enable the tube to fit beneath a bench, preferably made of a metallic material to provide good heat conductivity.  Openings are pro-vided in the tube to emit air beneath the bench in order to heat the bench and thereby to provide much needed warmth to persons sitting on the bench. Additional openings are arranged to emit the heated air at an angle chosen to direct the air toward the back part of the knees of persons sitting upon the bench.  High velocity jets of heated air emitted from such open-ings may also be utilized as handwarming means for simultaneously warming the hands of a large group of persons in the vicinity of the tube by place-ment of the hands into the jets of heated air being emitted by the tube without danger of burning.  The lightweight collapsible nature of the apparatus greatly facilitates both assembly and disassembly as well as the transportability of the portable heating system.

Abstract: ABSTRACT OF THE DISCLOSURE   A lighting feedback control system for applying AC power to at least one lamp, which includes a conduction angle controlled phase switching cir-cuit connected in series with the lamp and an AC power source for switching power across the lamp, and a line switching circuit for enabling the appli-cation of AC power to the lamp through the phase switching circuit.  A light sensor is provided for generating a light control signal indicative of the amount of ambient light present in the predetermined location.  Coupled to the light sensing circuit is a phase angle conduction control circuit which generates and applies to a control terminal of the phase switching circuit a phase control signal to control the phase angle conduction time of the phase switching circuit based on the amount of ambient light measured by the light sensing circuit to maintain a constant level of lighting.  Integrated within the phase angle conduction control circuit is an RC filter circuit which gradually increases the phase angle conduction time switching circuit from zero, or a predetermined minimum value, to a steady state phase angle conduction time based on the ambient light conditions sensed by the light sensing circuit, after power enabling by the line switching circuit.

Abstract: ABSTRACT A system is disclosed for positioning a transducer with respect to a disk surface responsive to analog signals generated in the transducer. Equally spaced synchronization signals establish a lock between a voltage con-trolled oscillator and the rotating disk.  Track seeking is accomplished using a Gray coded absolute track address system uniquely identifying each track. Once the target track is reached, an analog signal generated in response to odd numbered and even numbered bits on alternate tracks, produces a position error signal for returning the transducer to its centered position.  Improved coarse positioning is the result of the sensing of transitions or zero crossings of the analog transducer signal for more reliable signal detection and closer spacing of servo information.

Abstract: ABSTRACT A mounting arm is disclosed on one end of which a piece of electronic or other equipment is mounted and the other end of which is detachably fastened to the edge of a supporting surface.  The arm has three moving joints that permit the equipment fastened thereto to be moved with multiple degrees of freedom for desired positioning of the equipment.  One joint utilizes a friction washer assembly and a preloaded torsion spring  counterbalancing the weight of the equipment.  The torsion spring tension is adjustable to compensate for differing weight equipment on the one end of the arm. Another joint utilizes a friction ball joint arrangement having double concentric friction ball surfaces in an assembly that permits multiple degrees of freedom of motion and is easily removed from the remainder of the arm without disassembling the ball joint.
