Abstract: ABSTRACT     A product and method for increasing fertility in sheep.          By "increasing fertility" is meant increasing the potential of a flock of sheep to multiply by increasing ovulation in ewes.          The product is an immunogenic conjugate of 4-androstene-3, 17-dione and a soluble milk protein (SMP):  6-hydroxyandrost-4-ene-3, 17-dione 6-hemisuccinyl:  SMP.  The method comprises immunizing the ewes in a flock of sheep against 4-androstene-3, 17-dione by administering 6-hydroxyandrost-4-ene-3, 17-dione 6-hemisuccinyl SMP at the rate of 3 to 5 mg per ewe.  In previously untreated ewes, two administrations are required at between 8 to 9 and 4 to 5 weeks before the planned commencement of mating.  Subsequent administrations are annually and are recommended at 5 weeks before the commencement of mating.

Granted: 1991-09-17
Abstract: ABSTRACT OF THE DISCLOSURE           There is a metallic gasket comprising: a compensating plate having a combustion chamber hole and a folded edge which is formed by folding back the edge on the side of this hole; an intermediate plate laminated onto the compensating plate; and an elastic metal base plate having a bead which is laminated onto at least one of the compensating and intermediate plates.  This gasket is further provided with a compensating portion having a predetermined thickness consisting of the compensating plate and the edges of the intermediate plate and base plate.  There is also another metallic gasket comprising an elastic metal base plate having a circular bead so as to surround the combustion chamber hole and a compensating portion which is provided for the edge on the side of the combustion chamber hole of the base plate so as to surround this hole.  A spring constant of the bead increases as the distance from the bolt fastening portion increases, thereby allowing the uniform sealing pressure to be applied to the sealing portion. A thickness of the compensating portion gradually increases as the distance from the bolt fastening portion increases.  With this gasket, the increase and decrease in the gap between the deck surfaces are prevented and the stable sealing effect is obtained.

Abstract: ABSTRACT OF THE DISCLOSURE     A channel bank speech synthesizer for reconstructing speech from externally-generated acoustic feature inforamtion without using externally-generated voicing or pitch information is disclosed.  An N-channel pitch-excited channel bank synthesizer (340) is provided having a first low-frequency group of channel gain values (1 to M) and a second high-frequency group of channel gain values (M+1 to N).  The first group control a first group of amplitude modualtors (950) excited by a periodic pitch pulse source (920), and the second group controls amplitude modulators excited by a noise source (930). Both groups of modulated excitation signals are applied to the bandpass filters (960) to reconstruct the speech channels, and then combined at the summation network (970) to form a reconstructed synthesized speech signal. Additionally, the pitch pulse source (920) varies the pitch pulse period such that the pitch pulse rate decreases over the length of the word.

Abstract: METHOD OF DETERMINING ENDOTHELIAL CELL COVERAGE OF A PROSTHETIC SURFACE     ABSTRACT        Determination of the effectiveness of endothelial cell seeding upon a vascular graft surface within the operating room environment would be desirable to maintain quality control in any clinical trial,  In this study, five fluorescent stains, mithramycin, Hoechst 33342, sulfofluorescein diacetate, Nile red, and rhodamine 123 were evaluated for their ability to fluorescently label endothelial cells on graft material and subsequently allow determination of seeded cell number and cell spreading.  Of these agents, rhodamine 123 produced the most desirable characteristics.  It allowed excellent cell visualization after a 30 minute incubation.  Unlike the other four stains, using rhodamine 123 caused the cellular cytoplasm to fluoresce bright orange at a 510 nm excitation wavelength while the underlying dacron or expanded polytetrafluoroethylene demonstrated minimal autofluorescence.  No inhibitory effact on cell attachment to plastic or subsequent cell growth in culture was observed.  This technique can be utilized in the operating room to visualize part or all of an endothelial cell-seeded graft and to permit a quantitative as well as qualitative evaluation of the seeding process.

Abstract: SCROLL TYPE FLUID DISPLACEMENT APPARATUS WITH IMPROVED FIXED SCROLL CONSTRUCTION            ABSTRACT OF THE DISCLOSURE      A scroll type fluid displacement apparatus including an orbiting scroll and a fixed scroll, each having an end plate and a spiral element is disclosed.  The spiral ele-ments interfit at an angular and radial offset to form a plurality of line contacts between the spiral curved sur-faces to define at least one pair of fluid pockets.  A driv-ing  mechanism  is  operatively  connected  to  the  orbiting scroll for orbiting the orbiting scroll relative to the fixed  scroll  while  preventing  rotation  of  the  orbiting scroll.  This changes the volume of the fluid pockets.  A plurality of threaded holes are formed through the end plate of the fixed scroll for attaching the fixed scroll to the inner end surface of projecting portions of the compressor housing.   The projecting portions extend toward the fixed scroll and have threaded holes formed therein.  A bolt is screwed through the fixed scroll holes and into the holes in the projecting portions to attach the fixed scroll to the housing.

To prevent a gap from   remaining  in  the  closed  position  between  the peripheral  edges  of  the  lid  liner  and  fixed  liner opening,  which  would make possible penetration of noise into  the  vehicle  interior,  it  is  provided  that the peripheral  edge  of the lid liner possesses a downwardly facing   bearing  surface,  opposite  which  there  is  a correspondingly  upwardly  facing  counter-surface at the peripheral  edge of  the  fixed liner opening, in such a manner  that  the bearing surface and the counter-surface bear  against  each  other  without  a  gap in the closed position.    As soon as a slight upward movement occurs, the  bearing  surface  lifts  off  the counter-surface to form a ventilating gap.
