Abstract: ABSTRACT OF THE DISCLOSURE     An apparatus and method for sealing the wall of a concrete pipe.  The apparatus includes a frame having two longitudinally-opposed slidable carriages mounted at the horizontal top portion of the frame.  Both carriages support two axially-aligned longitudinal and inwardly-extending cylindrical insertion members of a diameter slightly less than the inside diameter of the pipe.  These members are movable by their respective carriage into the axial bore of the concrete pipe, sealing the same at both its ends.  One of the insertion members is provided with a tube communicating with the sealed axial bore at one end and with a source of pressurized sealing fluid at its other end.  The concrete pipe is first closed by the insertion members, then sealed with sealing fluid fed under pres-sure in the annular zone defined between the pipe and insertion members.

Abstract: ABSTRACT           A device for use with an eraser of a rubber compo-sition having magnetic particles dispersed therein.  The de-vice has a permanent magnet for attracting the magnetic dust created by use of the eraser.  For the ready removal of the collected dust the device further comprises a shield normal-ly enclosing the magnet.  When held close to or in direct contact with a dust collecting wall forming a part of the shield, the magnet attracts eraser dust therethrough.  The eraser dust attached to the dust collecting wall can be readily released, as into a suitable receptacle such as a trash can, as the magnet is moved away from the dust col-lecting wall as by being pulled out of the shield.  The device may incorporate a magnetic eraser to provide a con-venient eraser/dust collector combination, as in some embod-iments disclosed herein.  Additional embodiments suggest the combined use of a brush for collecting eraser dust, and the provision of an open space for confining the collected dust on the dust collecting wall of the shield.

Abstract: METHOD OF GROWING CHEESE STARTER MICROORGANISMS            Abstract of the Disclosure An improved method of growing acid-producing microorganisms (bacteria) used in cheese making is provided which gives enhanced bacterial counts and activities, and yields proper coccus/rod ratios in the case of mixed cultures used for making Italian cheeses such as mozzarella.  The preferred method involved inoculating  a  starter  medium  with  the  appropriate microorganisms,  followed by  initial  incubation until the pH of the medium drops to about 3.9-5.5; at this point the pH is raised to about 5.5-7.5, typically by the addition of a base such as sodium hydroxide,  The medium is then allowed to further incubate to comple-tion.   In particularly preferred forms,  the starter medium includes whey, nonfat dry milk, and a minor proportion of lecithin, inasmuch as this medium gives enhanced results when used in conjunction with the improved method.

Abstract: ABSTRACT OF THE DISCLOSURE    The invention relates to a quadrupole for resistive matching of a reactance of the RLC type connected in series or in parallel, which permits to compensate for the loss of gain of an amplifier as the frequency rises, in a manner independent of the frequency.  This quadrupole comprises two impedance circuits Z1 and Z2 in series between an input terminal and an output terminal, and in parallel with these, a third impedance circuit Z3. It also comprises a fourth impedance circuit Z4 connected between the point common to the first two circuits Z1,Z2 and the point common to the two other terminals of the quadrupole.  The reactance which is to be matched is Z3 if it is of the RLC type connected in parallel.  It is Z4 if it is of the RLC type connected in series. The values of the three other impedances Z1,Z2 and Z4 or Z3 are related so that the input impedance may be equal to the output impedance.

Abstract: ABSTRACT OF THE DISCLOSURE A needle valve having improved accuracy and wear characteristics is disclosed in which the valve stem is subjected to a constant force to prevent backlash throughout its entire movement with respect to the valve seat.  In addition, the needle contained within the valve stem has a tapered end which moves within the cylindrical bore in a valve seat to control fluid passing through the valve and such needle is affixed to the valve stem only at its other end remote from its tapered end.  The needle thus floats for a substantial portion of its length and its tapered end is relatively flexible and free of movement.  The needle is, however, angled with respect to its valve seat such that the needle physically makes contact with the internal surface of the valve seat and maintains that contact throughout its lateral movement within the valve seat.

Abstract: Abstract An improved color picture tube has an inline electron gun for generating and directing three inline electron beams along initially coplanar paths toward a screen of the tube.  The beams pass through a deflection zone adapted to have two orthogonal magnetic deflection fields established therein.  A first of the fields causes deflection of the beams perpendicular to the inline direction of the beams, and a second of the fields causes deflection parallel thereto.  The improvement comprises the electron gun including four magnetically permeable members located near the exit of the electron gun in a fringe portion of the deflection zone.  A first and a second of the members are located between the center beam path and a first and a second outer beam path, respectively.  A third and a fourth of said members are spaced from the first and second members, respectively, and located on the outside of the respective outer beam paths.  The first and third members and the second and fourth members bypass a part of the fringe portion of each of the two orthogonal deflection fields around the respective outer beam paths, while allowing another part of each of the same fringe portions to pass through the respective outer beam paths.  The first and second members bypass a part of the fringe portion of each of the orthogonal deflection fields around the center beam path, while allowing another part of each of the same fringe portions to pass through the center beam path.

Such catalysts are are prepared by introducing a substantially pentavalent vanadium-containing compound and a pentavalent phosphorus-containing compound into an alcohol medium capable of reducing the vanadium to a valence state less than +5 in the presence of an alcohol-modifying agent to form a phosphorus-vanadium mixed oxide catalyst precursor.  The catalyst pre-cursor is recovered, dried, formed into desired structures, and calcined at temperatures from about 250° C to about 600° C.  The catalysts are highly effective in that they exhibit a weight/weight productivity of at least 70 grams of maleic anhydride per kilogram of catalyst per hour.

The ends of the loop are in the form of a plastic snap connection with a pin and a cooperating sleeve, the halves of the loop being united permanently merely by pressing them together.  The ends of the loop provide abutment shoulders which prevent the loop from sliding through the transverse passage.  Connected to the loop under the cables is a cable supporting surface, the ends of which are bent downwardly.  Located thereunder is an eye for a clamping strip.  The latter is located in the lateral area, at the side of the cables, in slots in the loop, and is guided and tightened by a clamping eye.
