Filed: 1985-03-28
Abstract: The preparation of poly(arylene ketones) and in particular all para-linked poly(arylene ether ketones) by Friedel-Crafts polymerization in the presence of a Lewis acid generally results in an intractible reaction product difficult to remove from the reaction vessel and difficult to purify. The addition of a liquefaction agent, such as a hydrogen halide and in particular hydrogen chloride, to the reaction mixture, results in a tractible gel or a liquid which can be readily handled. The hydrogen halide is preferably under pressure and a diluent may also be added along with the hydrogen halide.

Abstract: The invention concerns a method and an apparatus for measuring the level of a material with microwave signals. The apparatus consists of a signal processing unit (10) and a transmitter unit (1) of known type. The transmitter unit produces a measuring signal having a frequency (f m ) corresponding to the distance (H) to be measured and a reference signal having a frequency (f,) corresponding to an accurately known length (L). In the signal processing unit (10) the reference signal is multiplied by a selectable number (AQ) which is proportional to the quotient of an assumed value for the distance divided by the known length (L), after which the frequency is divided by a fixed number (Z) so that the frequency of the signal after multiplication and division becomes equal to the expected frequency of the measuring signal. Thereafter the control signal thus produced is mixed with the measuring signal, for determination of the phase difference between them which is sampled in each of a succession of regular sampling intervals, and the change in phase difference through the successive sampling intervals is calculated for determining a correction term for the assumed distance.

Abstract: The plough consists of two portions separable by rams (72). Each portion comprises a beam (14, 16) joined to a plough body part (18, 20). The portions include two pairs of longitudinally-spaced arms (69) interconnected by pivots (70). At each end of the plough a support including bearers (61) is closed by a ram (59) to entrap the pipeline (26). Another ram lifts the support to raise the pipeline between the plough body parts (18, 20). The support ram is connected to a pressurised accumulator so that the support rollers (62) are kept against the pipeline (26) as the plough rises and falls and pitches. The elevated positions of the arms (69) and the relatively short separation between the two pairs of arms (69) allows the plough to descend and pitch relatively to the pipeline. In a modification the two beams are joined by rigid bridging structure and the plough body parts are pivotally connected to their respective beams. In other modifications the supports are dispensed with; or only one is used.

Abstract: A tire press, loader and method employs a stationary bottom mold section (181) and a vertically movable top mold section (176) which moves upwardly to open the press clearing the area therebetween for discharge of the cured tire and loading of the green or uncured tire. The press loads the green tire initially into the top mold section centering and holding the top bead of the green tire on the bead ring of the top mold section. To position the uncured tire for such top loading there is provided a loader (35) which engages the uncured tire at the lower shoulder of the tread area. The loader includes pivotally movable chuck sector assemblies (113), each mounted on a ring (98). The ring can readily be centered with respect to the axis of the mold sections and each assembly can be moved concurrently uniformly radially of the ring to accommodate tires of different sizes. The loader elevates the uncured tire from in front of the press and then positions it within the open press at the proper elevation with respect to the top mold section after the cured tire has cleared the press. The top mold section includes a mechanical chuck the segments (163) of which then extend to flower from cylindrical form to a conical form of increasing apex angle and then to a horizontal plate form in which they are locked. During opening of the press the bladder (161) after at least partial deflation and the bringing of the bladder clamp rings together overlies the bottom bead of the cured tire. This ensures that the tire properly remains on the bottom bead ring during stripping from the upper mold half and then the lower mold half,and as the bladder is drawn into the bladder well or bead lift can.

Abstract: A carrier wave recovery system for a slotted ALOHA system is disclosed. A reference carrier wave is provided by a voltage controlled oscillator (20) whose control signal (S4) is formed (adder 18) as the sum of a mean error signal (S6) and the current error signal (S3) derived by a phase comparator (12) from the input (S1) and reference (S2) signals. An averaging circuit (16) provides the mean error signal (S6) as the mean of the current control signal (S4) and the previous control signal stored in a register (28). In a time slot where no burst is input, the frequency of the oscillator (20) is locked to the mean value of carrier wave frequencies of bursts which were received in the past, thereby allowing a minimum of initial frequency offset to occur. In an alternative embodiment, the mean error signal is derived from stored maximum and minimum values of the control signal so that the oscillator frequency is controlled at initial pull-in to an average frequency of the highest and lowest carrier wave frequencies of an input burst signal.

Abstract: The present invention provides a disposable absorbent article such as an incontinent pad that is both comfortable and suitable for absorbing and containing large volumes of body liquids rapidly without leakage, especially a subsequent gush of liquid. Such an absorbent article comprises a liquid pervious topsheet, a liquid impervious backsheet, a layered expandable absorbent core positioned between the topsheet and the backsheet, at least two resilient shaping members, an acquisition channel, a liquid acquisition zone and at least two liquid impervious shelves. The present invention also relates to an absorbent article provided with an expandable overwrap having an expansion means for allowing the overwrap to expand when the absorbent core swells when wetted. 
     The overwrap of the absorbent article is provided with an expansion means for permitting the overwrap to expand as the absorbent core swells when it is wetted. The expansion means is a releasable tack or other means that releases the overwrap when a slight shearing or peeling force or action is applied to the expansion means. Thus the swelling of the absorbent core is less likely to deform the shape of the pad or cause a loss of the absorptive capacity of the article, escpecially for subsequent gushes of liquids.

Abstract: A method for surface treating of thin substrates such as semiconductor wafers, wherein a semiconductor wafer formed with deep and minute trenches on its surface is horizontally placed on a spinner in a chamber with its trenched surface directed up, and then ultraviolet light is emitted to the surface of the wafer to dissolve impurities sticking in the trenches, and thereafter etchant is spouted from a nozzle to the trenched surface of the wafer being spinned about a vertical axis at a high speed, and next the inside of the chamber is rendered at a lower pressure than atmospheric pressure and the atmospheric pressure is recovered after the lapse of a predetermined time, and thus a series of these steps of etchant supplying, pressure reducing, and pressure recovering are carried out until the complete entrance of the etchant into the interior surfaces of the trenches is effected, so as to even or smooth the interior surfaces, and finally the wafer is treated with rinsing, and heating and drying.
