Abstract: ABSTRACT OF THE DISCLOSURE     Improved low linting, low sodium ion content, wettable nonwoven wiper is provided through the use of a treatment involving a mixture of wetting agents.          The wiper of the invention maintains the excellent wiping and low linting characteristics of nonwoven wipers while greatly reducing the amount of sodium ions pre-sent in the wiper and avoiding contamination problems especially prevalent in wipe applications for the electronics industry.  Specifically, the combined wetting agent treatment includes a mixture of sodium dioctyl sulfosuccinate such as Aerosol* OT and a nonionic surfactant such as alkyl phenoxy ethanol (Triton*X-100).          The preferred mixtures are about 25 to 75% sodium dioctyl sulfosuccinate with a ratio of about 40 to 60 preferred and about 50/50 especially preferred.          The result is a wiper having essentially the desired wettability of those made with 100% sodium dioctyl sulfosuccinate wetting agent and yet having only about half the sodium ion content.  The wiper, therefore, can be employed advantageously in clean room applications such as the manufacture of micro-electronic devices where the presence of greater amounts of sodium ions can be very detrimental due to changes of electrical properties of the semiconductor devices.  Substrates for the wiper may include various synthetic filamentary material such as polyolefins, including polyethylene *trade mark and polypropylene, and others which will be apparent to those skilled in the art.

Title: Stabilisation of compounds, and the use of stabilised   compounds
Inventor: REID PAUL I
IPC: G03C1/73
Filed: 1982-07-05
Granted: 1984-11-20
Abstract: ABSTRACT:      The stabilisation of selected photochromic compounds, selected from certain fulgides and fulgimides, is made possible by associating with such compounds a clay mineral having an expanding crystal lattice, which can stabilize a selected photochromic compound in a higher-energy coloured form.   The stabilized photochromic compound may be one included in a coating composition, such as a paper coating composition, or may constitute or be incorporated in a filler for a papermaking furnish or for a plastics material. The stabilizer serves to maintain the photochromic compound in its higher-energy coloured state or one of its higher-energy coloured states, thereby tending to prevent deterioration of colour as the photochromic compound converts to an uncoloured or weakly coloured lower-energy state.

Abstract: ABSTRACT OF THE DISCLOSURE A reinforcing member for use in a grouted anchor is an axially elongated steel rod with hot-rolled helically extending ribs formed on its outside surface.  The ribs form a discontinuous helical thread onto which a connecting or anchoring member with a corresponding counter-thread can be attached.  The rod has a circularly shaped outside surface with oppositely disposed axially elongated recesses formed in the outside surface and located between the adjacent ends of the discontinuous ribs.  The recesses provide the rod with a necked-down cross-sectional appearance.  Axially elongated tubular members are positioned within the recesses and the tubular members are dimensioned so that they do not project outwardly beyond the circular line defining the outside surface of the steel rod.  When the reinforcing member is inserted into a bore hole, the tubular members within the recesses are protected against mechanical damage.

Abstract: ABSTRACT A method and an apparatus are provided for con-trast intensification in the reproduction of masters in the field of electronic image processing by engraving devices and scanners.  In the image-point wise, opto-electronic master scanning, two outer field signals are obtained in addition to the image signal by scanning a first outer field and a larger, second outer field.  A first differential signal and a second differential signal are generated from the image signal and the outer field signals and a third differential signal is gener-ated from the two outer field signals.  The first differential signal is combined with at least one of the other two differential signals to form an auxiliary signal which is added to the first differential signal in order to obtain a correction signal.  The correction signal is then superimposed on the image signal for the purpose of contrast intensification.  By employing a second outer field signal, it is particularly the disturbing edges around hard master contours which are avoided.
