Abstract: Abstract of the Disclosure The invention relates to an apparatus for treatment of water comprising inclined lamellae arranged so that settling materials as well as floating materials are separated from the water.  The apparatus is devised so that the water flows in opposite directions through separate spaces between the lamellae, wherein heavy materials (sludge) settle to the bottoms of the spaces while floating materials (scum) are retained and separated in a chamber where the water changes its direction of flow. The apparatus may be arranged for separation of sludge in two fractions and for purification of the water by a combination of flotation by aeration and settling.  The apparatus is useful for all types of purification processes based on separation by settling and flotation within the water and sewage treatment art.  Especially of interest is the favorable application of the apparatus for treating storm water and overflow water.

Abstract: ABSTRACT OF THE DISCLOSURE           A torque transmitting device for insertion into a bore in a workpiece, the device being, for example, a stud extractor, has slots spaced around the periphery of a shaft and extending longitudinally of the shaft, each of the slots having a bottom surface inclined towards the periphery of the shaft, and a workpiece-engaging blade in each of the slots.          Each blade is formed with an outer cutting edge for biting engagement with the wall of the bore and has, at one of its end, a radially outwardly extending projection.  An annular blade retainer extends around the blades and the shaft and engages the projections for retaining the blades on the shaft, the retainer being displaceable along the shaft.  A nut in threaded engagement with the shaft serves for longitudinally displacing the blades on rotation of the nut relative to the shaft.

Abstract: ABSTRACT OF THE DISCLOSURE      A circuit for efficiently operating two arc discharge flashlamps.  The lamps are series connected and directly coupled through series circuitry across an alternating current (AC) source.  A storage capacitor is connected between the function of the lamps and one terminal of the source.

Abstract: ABSTRACT        An ink writing tip includes a housing with a ball retained in a socket at one end of the housing.  A fibrous feed core having ink feeding capillaries extends into a bore in the housing from the other end thereof.  Ink is transferred from a source to the ball via a grooved feed passage between the bore and socket.  More reliable ink transfer from the core to the grooved feed passage is achieved by inserting the feed core into the end of the grooved feed passage remote from the ball in such a way that the core material is substantially uncompressed within the grooves of the feed passage and assumes substantially the cross-section of the grooved feed passage.

Abstract: Case 77050 METHOD OF SIZING PAPER AT THE SIZE PRESS AND RESULTING WATER-RESISTANT PAPER ABSTRACT A method of sizing paper at the size press of a Fourdrinier-type papermaking machine, and the resulting water-resistant paper. A starch which has been reacted with octenyl succinic anhydride is applied to a formed paper web from the size press. The starch com-bines with a multivalent metal ion (aluminum) already present in the paper web to become hydrophobic, and thereby impart a high level of water resistance concentrated at the surface of the paper. The sub-ject method attains water resistance in the finished paper which is equivalent to internally sized papers using combinations of alum and rosin applied at the wet-end of the papermaking process. Economies in the use of the starch derivative are realized by means of the sur-face sizing method disclosed because the starch derivative is concen-trated at the surfaces of the paper.

Abstract: ABSTRACT OF THE DISCLOSURE       Improved means are disclosed for supporting the cut-ting teeth on the periphery of a rotating cylindrical drum ice cutter affixed to a floating arctic structure.  The cutting teeth are individually removably affixed to brackets which extend spirally (either continuously or in segments) around the drum periphery and are supported in spaced re-lationship radially outwardly therefrom by very sturdy struts.          Several benefits are obtained with this configuration:   (1) hydrodynamic drag is minimized; (2) the teeth-support struc-ture can be made more rugged than individual ones for each tooth; (3) the teeth can be configured for a minimum of re-placeable material at the cutting tips; (4) more free volume is available around the drum periphery for disposal flow of disaggregated material and (5) tooth spacing can be readily adjusted for optimum performance according to requirements.

Abstract: Abstract of the Disclosure Hyperacidified tumors having high .beta.-glucuronidase activity can be treated with glucuronides with aglycones toxic to the tumor cells with great safety toward the rest of the body by first administering an alkalinizing agent in an amount sufficient to maintain the pH level of non-tumor tissues at approximately 7.4 during the glucuronide treatment.  This will cause inactivation of .beta.-glucuronidase activity in the rest of the body.  When nitrile-containing aglycones are used sodium thiosulfate is also administered to avoid cyanide poisoning.  Novel glucuronides are disclosed the aglycones of which exert a higher toxic effect in an acid environment or are water-soluble only in an alkaline environ-ment.  Such compounds have particular utility with the above process.  By substituting radioisotopes into the aglycone, diagnosis and in situ radiation therapy may be accomplished. Bacterial cells having .beta.-glucuronidase activity may also be diagnosed and treated in accordance with the present invention.  A urine test is disclosed to determine the amount of free glucuronic acid in the urine which is an indication of the presence of a tumor in the body having high .beta.-glucu-ronidase activity.  Novel methods of synthesizing the glucu-ronide used in the present invention are also disclosed.
