Abstract: According to the present invention a vaccine can be prepared containing a mutant Serpulina hyodysenteriae which is defective in its production of biologically active hemolysin. The mutation by which Serpulina hyodysenteriae is made defective in its production of hemolytically active hemolysin is established by means of genetical engineering techniques. Such mutations comprise e.g. deletion of part or the entire gene coding for hemolysin and/or nucleotide sequences controling the production of hemolysin, or insertion of an extra nucleotide or polynucleotide into the gene encoding hemolysin and/or the nucleotide sequences controling the production of hemolysin, or a combination of said deletion and insertion. These vaccines are useful in the prevention of Serpulina infections in susceptible animals such as swine.

Abstract: A combination valve in a side port adapter prevents back flow through the side port and through a main channel has an adapter (11) with a main channel (13) along an axis thereof. The adapter has a side port (12) that intersects with the main channel for flow therethrough. A resilient member (19) with a passage therethrough has therein a check valve located normal to the axis and across the passage. The check valve opens with flow along the axis in a direction and closes to flow in an opposite direction. The resilient member normally closes the intersection until the member deflects when fluid pressure within the side port exceeds its resiliency. The check valve is a web across the passage with a slit that is normally closed. The web shape is a duck bill. The main channel has an inlet and an outlet positioned along the axis. The outlet can be connected for fluid tight communication to a catheter or other fluid line. The inlet is in fluid communication with a fluid supply to provide flow through the main channel to the outlet. The resilient member and the main channel have a cylindrical shape of a circular cross section. The resilient member has an edge at a distal end thereof. The adapter has an annular shoulder within the main channel distal along the axis and relative to the side port to locate the edge. A method has the steps of providing an adapter with a main channel and a side port, placing a resilient member having a passage therethrough in the main channel to prevent flow from the main channel to the side port and providing a duck bill check valve in the passage to permit flow through the main channel in one direction and prevent flow in the opposite direction. The valve and adapter are packed and sterilized. <IMAGE>

Abstract: A plastic sheet (10), preferably of plasticized partial polyvinyl butyral, for a laminated safety glazing (10), having means dispersed on its surface, preferably comprising a multiplicity of spaced projections (56), capable of resisting adhesion to a rigid panel (52, 54), such as glass, of such a glazing when the sheet is laminated to the panel, the area of the sheet surface without such dispersed means having high affinity for adhesion. The projections physically block adhesion of a dispersed area of the sheet to the panel in that the means on the sheet surface have no or weak interfacial adhesion. The multiplicity of space projections also have low or no affinity for adhesion when in blocking contact with each other or with another plasticized partial polyvinyl butyral surface and thereby increase blocking resistance. Also, a laminated glazing (10) having improved impact strength comprising a), b) and c) in sequence: a) a glass layer (52); b) a plasticized layer (10) containing partial polyvinyl butyral; c) another glass layer (54); and d) means (56) dispersed on the surface of at least one of the foregoing layers capable of resisting adhesion to the layer with which it is in contact, the area without said dispersed means of said at least one of the foregoing layers having high affinity for adhesion to the layer with which it is in contact; said laminated glazing at a specific pummel adhesion having a greater mean break height than that of a laminated glazing containing layers a), b) and c) but without d).

Abstract: The invention relates in general to low bit-rate encoding and decoding of information such as audio information. More particularly, the invention relates to computationally efficient adaptive bit allocation and quantization of encoded information useful in high-quality low bit-rate coding systems. In one embodiment, an audio split-band encoder splits an input signal into frequency subband signals, quantizes the subband signals according to values established by an allocation function, and assembles the quantized subband signals into an encoded signal. The allocation function establishes allocation values in accordance with psychoacoustic principles based upon a masking threshold. The masking threshold is established by estimating the power spectral density (PSD) of the input signal, generating an excitation pattern by applying a spreading function to the PSD, adjusting the excitation pattern by an amount equal to a signal-to-noise ratio (SNR) offset sufficient to achieve psychoacoustic masking, comparing the level of the adjusted pattern to the threshold of hearing and generating a masking threshold which is equal to the larger of the two. The spreading function may be implemented by applying one or more IIR filters to the input signal PSD.
