Abstract: ABSTRACT     "Improvements in Mechanical Seals"     A mechanical seal for a shaft (10) exiting a housing (12) has an end plate (22) secured to the housing and a sleeve (26) secured to the shaft.  The sleeve (26) carries a rotary seal element (40) and the end plate a stationary seal element (52) which form a running seal at faces (48,50). A multipurpose bush (60) is a close fit on the sleeve (26), it positions a spring (64) pressing the seal elements (40,52) together, it carries a lipseal (78) and it prevents collar (30) securing the sleeve (26) to the shaft (10) from contacting the end plate (22) in the event that the sleeve becomes unsecured from the shaft (10). The bush (60) is constructed from spark resistant material.            A removable key 88 positions the sleeve (26), and hence the seal elements (40,52) and bush (60) with respect to the end plate (22) prior to tightening sleeve-security screws (32).

Abstract: ABSTRACT     A method of felling trees and a felling head for doing the same.  The method involves driving a horizontally sharpened blade on the felling head partially into a tree from one side and applying a selected force to the opposite side of the tree at a position above the cutting member, moving a driven saw on the felling head through the tree to cut the same and immediately the tree has been cut, shifting the same laterally onto a support plate.  The apparatus includes a frame having a hydraulically operated sweep arm pivotally mounted on the frame for movement toward and away from an area in which the trees are collected and a plate on the frame for supporting the butt ends of the trees.  The plate has a sharpened edge for penetrating a standing tree to be cut and an arm is mounted on the frame and movable toward and away from the cutting member so as to press the cutting member partially into the tree. A hydraulically driven chain saw is mounted on such arm and hydraulically operated for cutting through the tree as it is pressed against by the sweep arm.

Abstract: ABSTRACT OF THE DISCLOSURE              A structural metal sheet employed as an outer sheet for a railway vehicle, for example, is generally pretensioned in order to prevent buckling.  Hitherto, the pretensioning is effected by various methods after or during the assembly of a structure.  According to the invention, the metal sheet itself is pretensioned by a plastic working for increasing the flexural rigidity thereof.  Thus, there is no bear of buckling, and the appearance is improved as compared with the prior art.

Abstract: PROCESS FOR PREPARING CITRUS JUICE CONCENTRATE                 John R. Powers Robert S. Moore ABSTRACT OF THE INVENTION       A process for preparing a citrus fruit juice concentrate having a high level of citrus juice aroma and flavor volatiles is disclosed. The fruit juice concentrate has at least 33% solids including pulp, sugars, pectin. The citrus juice concentrate contains at least 60% of the volatiles naturally occurring in the juice .      The process involves stripping the volatiles from citrus juice at reduced pressures using a stripping agent, such as steam, at temperatures about 100°F (37.7°C) to about 160°F (71°C). The volatiles are condensed. The condensate can be separated into two fractions: a limonene-based stripper oil and an aqueous stripper essence. The aqueous stripper essence is concentrated, usually with a carrier material. The concentrated aqueous stripper essence composition contains most of the highly volatile aroma and flavor components of the juice. The concentrated aqueous stripper essence and stripper oil compositions are blended with the conventionally concentrated citrus juice to make a superior citrus juice concentrate. Both an aqueous essence (evaporator essence) and an oil essence (evaporator essence oil) can be recovered from the evaporation step. Both of these contain much less of the volatile components than normally would be recovered from the evaporator because these components were removed in the stripping step.      The devolatilized juice is also concentrated using conventional evaporation or concentration techniques.

Abstract: FLUID JET PRINT HEAD AND STIMULATOR THEREFOR              Abstract of the Disclosure A fluid jet print head includes an orifice plate defining a plurality of orifices from which fluid emerges, and a stimulator means mounted in contact with the orifice plate for vibrating the orifice plate to produce a series of bending waves.          The bending waves travel along the orifice plate and break up the fluid into drops of substantially uniform size and spacing.  The stimulator means includes a stimulator member of a length equal to an integer half wavelength of acoustic waves of a frequency f passing therethrough.  The stimulator member contacts the orifice plate at one end of the member.  A pair of piezoelectric crystals are mounted on opposite sides of the stimulator member and, when driven by an appropriate A.C. drive signal, cause acoustic waves of a frequency f to pass along the member.  The member is supported at a nodal plane.  The member may enter the print head manifold and contact the orifice plate internally, with a seal arrangement being provided at a nodal plane along the member.  Alternatively, a pin, mounted on the end of the stimulator member, such as a half wave member, may be used to transmit mechanical vibrations to the orifice plate.

Abstract: DISSOLUTION OF METALS                    UTILIZING A LACTONE                         ABSTRACT         Improved metal dissolution rates are obtained when using a solution containing sulfuric acid, hydrogen peroxide and a cata-lytic amount of a lactone such as .gamma.-butyrolactone, .epsilon.-caprolactone or .gamma.-valerolactone.           The present invention relates to the dissolution of metals in an aqueous bath containing sulfuric acid and hydrogen peroxide, and in particular to a novel bath composition capable of effecting the dissolution at high rates.  In one specific aspect the invention is concerned with etching of copper in the production of printed circuit boards.         BACKGROUND OF THE INVENTION         As is well known in the art, in the manufacture of printed electronic circuits a laminate of copper and etch resistant material, usually plastic, is used.  A common method of obtaining the circuits is to mask the desired pattern on the copper surface of the laminate with a protective resist material, which is imper-vious to the action of an etch solution.  In a subsequent etching step, the unprotected areas of the copper are etched away, while the masked areas remain intact and provide the desired circuiting supported by the plastic.  The resist material can be a plastic material, an ink or a solder.         In the last few years, the industry has more and more turned to hydrogen peroxide sulfuric acid systems for etching the electronic circuits boards, due to the low cost of the etching solu-tions and to the relative ease with which copper values can be recovered from the spent etch solutions.

Abstract: GRF ANALOGS ABSTRACT OF THE DISCLOSURE Synthetic peptides are extremely potent in stimulating the release of pituitary GH in mammals because they are the replicates of the native (hormone) releasing factor of the hypothalamus of the particular species, i.e. porcine, bovine and caprine.  These peptides contain the following sequence:                  wherein R28 is Ser or Asn; and R41 is Arg or Lys.  The peptide or a biologically active fragment thereof, or analogs thereof having well-known substitutions and/or additions, as well as nontoxic salts of any of the foregoing, may be administered to mammals and may be used diagnostically.  The peptides are particularly useful in stimulating the release of GH so as to accelerate growth in warm-blooded non-human animals of the particular species and/or to improve aquiculture.
