Abstract: ABSTRACT OF THE DISCLOSURE An annular extrusion die for extruding tubular thermoplastic materials, such as foamed thermoplastic, which incorporates an internal spider mandrel and a novel choke ring for eliminating striations in the extruded thermoplastic material while Imparting an improved control over the uniformity in the gauge or thickness of the extruded plastic material.  In order to more accurately control the uniformity in the gauge of the extruded plastic material; rather than varying the width of the gap or restriction in the die flow passageway formed by the choke ring which, in response to even minor changes in the gap width considerably changes the flow quantity, may overcompensate or overcontrol variations in the gauge thickness; there is varied the length of the land of the choke ring in the direction of material flow, in effect, in the machine direction, downstream of the spiders supporting the internal mandrel.

Abstract: TOUCH PANEL WITH AUTOMATIC NULLING     Abstract of Disclosure A touch panel has panel scanning signals selectively applied to the four sides of a touch sensing surface of the panel so as to establish alternating current voltage gradient in desired directions across the touch sensing surface. When the panel is touched, touch signals result and are utilized by a touch location circuit in determining the location of touch. The impedence touch current resulting from a user's, touch may also be determined and used. The touch panel circuit automatically compensates for any variations in touch signals which occur when the touch panel is untouched and automatically nulls the touch signals under such circumstances to enhance the accuracy of touch location determination .

Abstract: Abstract:         The present invention relates to a method and apparatus for defining fine-line features on a wafer.  The method comprises the steps of generating narrow-bandwidth laser pulses and directing the pulses via a lens and scanning assembly to form a variable-size variable-shape virtual source composed of the multiple pulses.  The method further includes relaying the virtual source through a reticle pattern to illuminate a substantial portion of the entrance pupil of a diffraction-limited low-loss projection lens made of a single optical material, and directing the reticle pattern via the projection lens onto the surface of the wafer.  The apparatus comprises a laser that inherently is characterized by a relatively wide bandwidth and a lens assembly disposed in the path of radiation from the laser which exhibits unacceptably large chromatic aberrations in response to the relatively wide bandwidth.  A unit is provided for sufficiently narrowing the bandwidth of the radiation to cause the assembly to exhibit acceptably low chromatic aberrations.

Abstract: TITLE:  SOD HARVESTER AND METHOD FOR         ROLLING SOD WITH GRASS SIDE OUT (Divisional) ABSTRACT OF THE DISCLOSURE     A sod harvester in which sod is cut, conveyed upwardly, and then travels downwardly over a floppy con-veyor and falls into a roll forming enclosure formed by a bottom conveyor and a vertical conveyor.  The floppy con-veyor swings downwardly at the start of roll forming, to reduce the free fall of the sod, and swings upwardly as the roll grows.  When the roll is formed, the bottom con-veyor is unlatched and tilts downwardly to discharge the roll,  at  the same time pulling  into cocked position a core tube injector arm.   When the roll discharges,  the bottom conveyor snaps upwardly, releasing the core tube injector arm which injects a fresh core tube into the roll forming enclosure.  The sod is rolled with its grass side outwardly to facilitate laying and to protect the grass roots.  A tray on a cart at the end of the harvest-er receives  the discharged  roll  and  can convey  it  to either side of the cart.   When the tray reaches either side of the cart, a cam tilts the tray to discharge the roll onto the ground clear of the next pass of the har-vester.

Abstract: Heavy metal compounds are removed from the filter dust of industrial plants by thermal separation, by heating of the filter dust in a reaction vessel (4) up to the vaporisation temperature and quenching of the resulting heavy metal vapours in a cooler (13), condensing, subliming and taking off. Carrier gas (9) or circulating gas (16) is used for fluidising the filter dust, or a vacuum pump (32) is used for vaporising the heavy metal compounds under reduced pressure. Additives are used for promoting the vaporisation or conversion of the heavy metals into more volatile compounds. In plants operating continuously or discontinuously, the fine dust is advantageously separated off before the removal of the heavy metals and further treated separately. <IMAGE>

Abstract: Method of stabilizing ground 3, for example fine-grained soil or clay, by producing subsidences in the ground by means of vacuum pumping comprises the formation of vertical drainage holes which are connected to suction pumps 7 in order to carry away drainage water, and bringing about a negative pressure in an area of the ground which is covered by an airtight tarpaulin 6 which is fixed to the ground at its edges, in which way atmospheric pressure contributes to said subsidences. The ground is frozen first so as to form ice beads which grow by virtue of the fact that water is drawn out of the ground/clay between the ice beads which in this way exert a consolidating pressure on the mineral grain aggregate of the ground. The frozen area 2 is then thawed by supplying heat, after which excess water is drawn out of the ground and the drainage holes by means of vacuum pumping in order to produce said subsidences, the treated area then appearing as a depression. <IMAGE>

Abstract: A serial-bit digital processing system uses registers and latches to synchronize samples and justify sign-bits. Nominally each processing block in the system includes a sign extend register (16) preceding an arithmetic element (18) and an output register (20) following the arithmetic element. Input registers of one arithmetic element may merge with output registers of the preceding arithmetic element. The sign extend registers include a serially coupled latch which is selectively controlled to pass serial sample bits or to replicate the sign bit. The respective registers are clocked with one of two clock signals (CLOCKN, CLOCKP) having different numbers of pulses per sample period and the length of the respective registers are selected so that at the terminus of each sample period the bits of each sample in the processing system are appropriately justified.
