Abstract: Regression associated antigens (RAAs) are identified in material from neoplastic cells by their immunological reactivity with regression associated antibodies from the serum of patients diagnosed as undergoing regression of a tumor. Regression associated antibodies (RAAbs) are identified by their absence during progression of a neoplastic disease state and by their presence in a diagnosed state of regression. The antigens are purified, used to monitor the condition of cancer patients, and production of antibodies and treatments employing those antibodies are described. It is also disclosed that RAAs are expressed by  M .  hyorhinis  and may be expressed by expression of provided nucleotide sequences in recombinant host cells. RAAs and nucleic acids encoding RAAs (or portions thereof) and RAAbs may be used in diagnostic assays and immunotherapy. RAAbs and fragments portion thereof may be used in passive immunization therapy and radioisotope or magnetic resonance scanning. A monoclonal RAAb and a hybrdoma secreting it are also provided.

Abstract: A bellows assembly (30) is secured to a retainer (40) by extrusions having a mushroom or arrow shaped cross section. Air flowing through the terminal (10) impinges upon an imper­vious film coving the central portion of the device and is diverted into two flow paths. Initially the flow paths ex­tend between the film and the cutoff plates (24,25) which coact to form a tight shut off. Downstream of the cutoff plates (24,25), the flow paths are between a porous foam covering the bellows and foam(50) surrounding the cutoff plates (24,25) to provide a sound reducing effect. If necessary or desirable, the back of the retainer (40) may be covered with foam or other suitable sound insulating material.

Abstract: Oxydiphthalic anhydrides of the formula
      are prepared by reacting a halophthalic anhydride with potassium carbonate in:
     (1) a solvent-free reaction medium wherein the molar ratio of halophthalic anhydride:potassium carbonate is greater than 2:1; or   (2) a high boiling solvent which improves the mixing of the components, and aids in subsequent purification of the product. The molar ratio of halophthalic anhydride to potassium carbonate is about 1.5:1 or greater.    The oxydiphthalic anhydride can be purified by filtering or centrifuging a hot solution of the oxydiphthalic anhydride in a high boiling solvent to remove impurities, followed by cooling the solution to precipitate the oxydiphthalic anhydride, which can be removed from the solution by filtration or centrifuging.

Abstract: The invention relates to a method of active attenuation of pressure pulsation in the stock fed into the headbox (10) of a paper or board machine in such a way that the pressure pulsations in the stock are measured and the water flow to be fed into the stock is controlled on the basis of the results of the measurement. The volume available for the stock flow is controlled by means of water flow changes. Pressure variations achieved by volume variations are arranged substantially in opposition in relation to the pressure variations to be attenuated thus attenuating the pressure variations in the stock. The invention also relates to an apparatus for carrying out the above method. The apparatus comprises a sensor (6) or a set of sensors, on the basis of whose output signal/signals a regulator (7) has been arranged to automatically control the water flow to be fed into the stock by an adequately fast valve arrangement (1) moved by the controlling element (2) of the regulator (7).

Abstract: A unipolar ignition of the invention provides a current waveform at the ignitor plug which initially rises relatively slowly, followed by a transition to a fast rising current which quickly peaks and thereafter slowly dissipates. Such a current waveform provides an initially hotter and longer lasting spark which does not harm the ignitor plug of the system or shorten its life expectancy. Neither does the spark create stress on the solid state circuitry which delivers the energy to the ignitor plug. To provide the foregoing spark and current characteristics, an inductor having a saturable core is in series with the ignitor plug, and it provides an initially high inductance which limits the rate of current rise at the plug as energy is transferred from an energy storage device to the plug. As the current through the inductor increases, its core begins to saturate and the effective inductance begins to decrease, allowing the current to rise more quickly. As energy is transferred to the ignitor plug, the increasing saturation, decreasing inductance and increasing current complement one another, causing the rate of current rise to increase quickly to a high value desirable for ignition. Related features of the invention provide for easy diagnostics of the spark and for timing an ignition sequence and providing a repetition rate which aids in a successful ignition.

Abstract: A process for preparing sucrose fatty acid esters by reacting sucrose and a fatty acid alkyl ester in an aqueous reaction system in the presence of a catalyst, adding water to the reaction mixture to dissolve it, adjusting the reaction mixture to a neutral pH region, adding a neutral salt to the solution to precipitate the sucrose fatty acid esters, separating and washing the precipitate with an acidic water, and subjecting the washing liquid to ultrafiltration. The precipitate washed with the acidic water is spray-dried in the form of an aqueous slurry to give a dry powder of the sucrose esters having low HLB, and the concentrate obtained by ultrafiltration is spray-dried to form a dry powder of the sucrose esters having high HLB, and the liquid obtained by separating the precipitate is contacted with a reverse osmosis membrane to recover sucrose. According to the invention, purifed sucrose fatty acid esters can be obtained without using an organic solvent, while sucrose can be recovered in high yield.

Abstract: In an imaging system (20) employing an array of detectors (22) and an optical system (26) for focusing rays of an image (24) upon the detectors, there is provided a protection system (50) in the form of a cell (56) of gaseous lasing material disposed along a path of the imaging rays. A pair of electrodes (64) and a supply of electric power (68) induces an electric discharge through the lasing medium to heat the medium so as to enhance interaction between intense laser radiation which might inadvertently or deliberately, be directed toward the array of detectors. The laser radiation induces still further heating of the lasing medium with a resultant absorption of a relatively narrow frequency band of radiation, at the lasing frequency, so as to prevent damage to the array of detectors while allowing scene radiation outside of the narrow band to be received by the detectors. A further detector (74) may be located offset from a path of propagation of the laser radiation for detecting fluorescent rays produced by interaction of the laser radiation with the lasing medium. If desired, a shutter (46) activated by a signal of the further fluorescent detector may be employed to provide additional protection of the array of detectors from the laser radiation.

Abstract: In the present pressure measurement process the damping signal of a tuning fork quartz manometer, which is a measure of the prevailing pressure, is so combined with the correction value proportional to the resonant frequency that a measurement result is obtained, which is independent of any contamination of the tuning fork quartz. Apart from the resonant frequency (fR) of the measuring quartz (11), preferably also the resonant frequency (fR') of a reference quartz (21) kept at constant pressure is determined. Thus, the damping signal (RS) can be corrected by a correction value proportional to the difference between the two reference frequencies (RR'-fR), which is substantially temperature-independent.
