Abstract: ABSTRACT OF THE INVENTION    A surgical clip applying device having a main body, a clip magazine coupled to the main body for holding a plurality of clips, clip deforming jaws coupled to the main body for receiving and deforming clips, a clip loading mechanism for loading clips from the magazine to a clip feed blade which moves clips from the clip magazine to the deforming jaws, and a spring activated actuating mechanism.  The clip loading mechanism includes a double ratchet apparatus coupled to a pawl for advancing the clips through the magazine. The actuating mechanism includes handle portions, a ratchet member having a cam follower which is coupled to a camming surface which is in turn coupled to one of the handle portions, a spring connected to the main body and the ratchet member, and a latch adapted to engage the ratchet member.  By movement of one of the handle portions with respect to the other handle portion, the camming surface engages the cam follower to store energy in the spring, which is retained therein via engagement of the latch with the ratchet member.  In operation, a slight movement of one of the handle portions with respect to the other handle portion disengages the latch from the ratchet member so that the energy stored in the spring is converted into rapid forward movement of the clip feed blade.  This forward movement causes the clip loading mechanism to advance a clip and, in addition, causes the clip feed blade to slide through the magazine to rapidly place a clip in the deforming jaws.

Abstract: HYDRAULIC POWER STEERING SYSTEM     Abstract of the Disclosure A hydraulic power steering system has a steering valve which operates in accordance with steering input signals generated by a steering wheel operated metering pump and follow-up signals generated by a pair of follow-up cylinders to effect a desired turn. The steering valve acts in response to a relatively large signal, representing a desired sharp or full turn, to interrupt or block the follow-up signal whereby sharp turns may be accomplished without requiring as many turns of the steering wheel as would be necessary if follow-up flow were nullifying the input signal.

Abstract: ABSTRACT          A triphonic sound system in which three in-dependent stereophonically  related   audio frequency source signals L, R and C are combined to derive three other audio frequency signals M, S, and T which re-spectively comprise (L + 1.4C + R), (L-R) and (-1.4C). In a preferred transmitter embodiment, useful in television broadcasting, the audio signals S and T modulate two quadrature-related sub-carriers of the same frequency to develop two double-sideband,  suppressed-carrier sig-nals,  the frequency of the subcarriers being suffi-ciently high as to assure a frequency gap between the lower sidebands of the modulated subcarrier signals and the audio frequency signal (L + 1.4C + R).  The afore-mentioned signals, and a pilot signal having a frequency which lies within the frequency gap, are combined and frequency-modulated onto a high frequency carrier for the purpose of transmitting the same to one or more remote receivers.  The receiver is operative in response to reception of the high frequency carrier to reproduce each of the audio frequency source signals L, R and C, and includes means for reproducing conventional monophonic and two-channel stereophonic broadcasts.  The described matrix equations are amenable to and useful with multi-channel television sound systems currently under con-siderarion for future broadcast service in the United States.

Abstract: ABSTRACT        A divider for a carton is formed from a one piece blank and includes a partion defining a handle.  The handle is secured in a stored position to an anchor panel of the divider by severable connections in the form of straps as that the handle can be moved outwardly into a carrying position.  The straps are connected to the anchor panel and handle at respective points lying on a line perpendicular to the line of severance between the anchor panel and handle.  The straps have a length greater than the distance between the connection points so that upon application of a force to separate the handle from the anchor panel, a couple is set up in the strap to promote tearing of the strap and release of the handle.

Abstract: ABSTRACT OF THE DISCLOSURE     A method for producing stable, layered electrets includes the steps of placing a thin sheet of glassy polymer or copolymer of high molecular weight, such as polyethylene terephthalate, between two, somewhat larger in plan form, sheets of polyvinyl chloride and/or polyvinyl acetate formu-lation, to form a sandwich structure which is then compressed and heated to approximately 300°F.  At this temperature the exterior polyvinyl chloride or copolymer sheets are polarized and displaced under pressure over the interior sheet to charge the interfaces of the exterior and interior sheets.  The heat, furthermore, bonds the peripheral edges of the larger exterior sheets to each other thus forming a hermetically closed container within which the charged interfaces will reside.          Alternatively, two or more sheets of electret (polymer) material may be pressed and heated against each other to a point where plastic deformation occurs but below melting.  At this point surface charges on each sheet induce internal charges or polarization which is then fixed by rapid cooling.

Abstract: TURBO-COMPRESSOR APPARATUS         ABSTRACT OF THE DISCLOSURE         A turbo-compressor apparatus in which the turbine section and the compressor section are placed back-to-back.         A non-rotating shaft axially supported in the apparatus sup-ports an anti-friction bearing which, in turn, rotationally support a rotor assembly.  A separating member preferably comprised of a material of low thermal conductivity is pro-vided between the turbine section and the compressor section.         A fully floating, non-rotating sleeve bearing incorporating both thrust and radial surfaces is allowed to float freely on the shaft.  Thus, thrust forces from the spinning rotor are initially absorbed at the large radial bearing surfaces located at approximately the center of the bearing and are thereby transferred to the small areas at either end of the sleeve bearing.  The thrust forces are finally transferred from the sleeve bearing to the stationary shaft.  The mech-anically locked sleeve bearing also serves to retain the rotor on the stationary shaft.  In the preferred embodiment, the stationary shaft is supported at only one of its ends, the unsupported end extending into a cylindrical opening in the rotor assembly which opening may be a blind hole.  The sleeve bearing has opening which receive rotation preventing means extending from the shaft.

Abstract: FILLER-CONTAINING POLYURETHANE(UREA) COMPOSITIONS      AND PROCESS FOR THE PRODUCTION THEREOF                 ABSTRACT OF THE DISCLOSURE The invention relates to a process for the production of polyurethane(urea) compositions which contain lignite and/or peat bound in an abrasion proof manner, which are preferably modified cationically and which have a very high water absorbability.  The compo-sitions are produced by reacting isocyanate-terminated prepolymers, which are preferably cationically modified, and which preferably have a functionality of more than 2.1, with more than the stoichiometric quantity of water in the presence of lignite and/or peat and optionally in the presence of organic and/or inorganic fillers and biomasses (living cells; living bacteria or enzymes). The corresponding polyurethane(urea) compositions contain up to 95% by weight of lignite and/or peat in the filler-containing polyurethane(urea) composition and are already swollen from production.  The water absorb-ability (WAF) value thereof when suspended in water is from 33 to 97% by weight of water.         The compositions can be used, in a form option-ally containing biomasses incorporated therein, as carriers in microbial synthesis processes for the production of complicated organic compounds, or as carriers for the growth of plants.
