The pressurizable chamber is defined by an internal, tubular, substantially nondistensible portion and a concentric tubular sleeve.  The nondistensible portion is crimped so that it may expand in diameter.  Upon expansion, the prosthesis assumes a straight, erect state. The sleeve may elastically bias the nondistensible portion to its flaccid state.  Fluid for filling the nondistensible portion may be stored in a rear fluid reservoir having a rigid internal stabilizer.

Title: Barking drum and method of heating same
Inventor: ALANDER KEIJO
IPC: B27L1/00
Filed: 1987-02-19
Granted: 1992-02-18
Abstract: ABSTRACT OF THE DISCLOSURE           For supplying pressurized steam into a rotating barking drum during the barking of tree trunks in order to thaw and warm the bark.  Steam is supplied into the barking drum from the periphery of the drum in a substantially radial direction through a distribution ring on the periphery of the drum and a stationary member in sliding contact with the ring.

Filed: 1987-03-11
Granted: 1991-01-29
Abstract: ABSTRACT PROCESS FOR THE PREPARATION OF BITUMEN      Process for the preparation of bitumen in which a residual fraction of a thermally cracked hydrocarbon feedstock is distilled under subatmospheric pressure at a maximum distillation temperature that corresponds with the boiling point at the subatmospheric pressure of hydrocarbons having an atmospheric boiling point of 455-540°C and at least a part of the distillation residue is recovered as bitumen.

Title: Digital filters and demodulators
Inventor: BARTON STEPHEN K
IPC: H04L7/02
Filed: 1987-04-27
Granted: 1990-12-11
Abstract: ABSTRACT    Digital representations of a signal are stored in a store (8) e.g. in the order of their occurrence.          Multipliers (9) sultiply the samples by coefficients (C1 to C36) representing a function with which the samples are to be convolved.  The signal is subject to variable time delays.  To compensate for the variable time delays sets of coefficients are stored, the sets representing the function with different time delays.  The set to be convolved with the signal is chosen in dependence upon the time delay of the signal.  A signal indicative of the time delay is derived from an input to the shift register and fed-forward.    The filter is preferably used in a digital demodulator of phase and/or amplitude modulated signals.

Title: Pre-s gene coded peptide hepatitis b immunogens, vaccines, diagnostics, and synthetic lipid vesicle carriers
Inventor: NEURATH ALEXANDER R
IPC: A61K47/48
Filed: 1987-04-28
Granted: 1991-04-30
Abstract: ABSTRACT OF THE DISCLOSURE         A hepatitis B vaccine containing a peptide with an amino acid chain of at least six consecutive amino acids within the pre-S gene coded region of the envelope of hepatitis B virus.  The vaccine being free of an amino acid sequence corresponding to the naturally occurring envelope proteins of hepatitis B virus and a physiologically acceptable diluent.  The peptide being free or linked to a carrier.  The carrier being a conventional carrier or a novel carrier including a lipid vesicle stabilized by cross-linking and having covalently bonded active sites on the outer surface thereon.  Such novel carrier being useful not only to link the novel peptide containing an amino acid chain with amino acids within the pre-S gene coded region of the surface antigen of hepatitis B virus, but can also be used to bind synthetic peptide analogues of other viral proteins, as well as bacterial, allergen and parasitic proteins of man and animals.  The peptides of the invention can be utilized in diagnostics for the detection of antigens and antibodies.
