Title: Improved meningococcal polysaccharide conjugate vaccine
Inventor: JENNINGS HAROLD J
IPC: C08B37/00
Filed: 1990-12-13
Abstract: Neisseria meningitidis group B polysaccharide (GBMP) modified by having sialic acid residue N-acetyl groups replaced by N-aryl groups exhibits enhanced immuno response thereto. In addition, induction of antibodies which cross-react with un-modified group B meningococcal and E. coli K1 capsular polysaccharide and other tissue cells having a common epitope is mini-mized. Conjugation of the modified polysaccharides with a physiologically acceptable protein such as tetanus toxoid induces the production of specific protective antibodies with negligible levels of GBMP-cross reactive antibodies, to thereby afford protection against infections caused by group B meningococci and E. coli K1.

Title: Process for using energy potentials, in particular with small temperature differences
Inventor: WOLF BODO
IPC: F24V50/00
Filed: 1991-05-29
Abstract: ABSTRACT OF THE DISCLOSURE            The invention relates to a process for using thermal energy potentials, in particular with small temperature differences between each other, or mechanical energy potentials, in particular environmental energy carriers such as sea currents flowing in opposite directions, sea currents and atmospheric air which occur in nature or are produced during secondary and environmental energy carriers produced in industrial processes for conversion and application of energy, and whose temperature differences are sufficient to drive power processes for generating electrical energy. The temperature drop between the energy potentials is used on site or nearby for electrolysis of liquid or gaseous water and metal oxides. The hydrogen evolved and the metals are combined with each other chemically to from metallic hydrides and then transported as energy carrier, i.e. synthetic fuels, to the site at which the energy is required, where they are burned with industrial oxygen or air in fuel cells, with release of electrical and possibly heat energy, or in special combustion chambers, with release of heat energy, to form metal oxides and water vapour.

Patent CA-2090408-A1 (CA)
Title: Optical communications system
Inventor: RARITY JOHN GILROY
IPC: H04B10/70
Filed: 1991-08-08
Abstract: An optical communications system (10) comprises a transmitter (12) and a receiver (14). A source (16) of correlated pairs of photons of conjugate energies provides first and second photon beams (38, 36). The first photon beam (38) passes through a modulated filter (50) to which a communications signal (52) is applied. A  variable spectrum beam (54) is produced which is con-verted to a timing signal (68) of macroscopic optical pulses (66). The second photon beam (36) and timing signal (68) are trans-mitted to the receiver (14). The received timing signal (84) is converted to a series of electrical timing pulses (90). The received sec-ond photon beam (82) passes through an unmodulated filter (94) matched to the modulated filter (50) when the signal (52) is not applied. The unmodulated filter splits the beam (82) into two conjugate spectra photon beams (96, 98) which are then converted to first and second series of electrical pulses (108, 110) respectively. The pulses (90, 108, 110) enter a coincidence counter (92) which records coincidences between the timing pulses (90) and the first series of pulses (108) and between the timing pulses (90) and the second series of pulses (110). Two coincidence rates are obtained and subtraction of one from the other yields an output communications signal (112).

Patent CA-2094541-A1 (CA)
Inventor: KREMER WILHELM
IPC: H04Q11/04
Filed: 1993-04-21
Abstract: Communications circuit connectivity in a bidirectional line-switched ring transmission system is continued in the presence of the failure of a first ring node for communications circuits terminated in the ring node which are redirectable to an alternate (dual hubbing) ring node. The communications circuits are redirected by establishing a bidirectional communications circuit to the alternate ring node. In one example, redirection of the communications circuits is further realized by not squelching communications circuits terminated in the failed ring node in a ring node adjacent the failed ring node on one prescribed side which normally would have been squelched, while squelching communications circuits terminated in the failed ring node in a ring node adjacent to the other side of the failed ring node.  This allows the redirectable communications circuits to be loop back switched so that they may be redirected to the alternate ring node. Then, the alternate ring node directly intercepts the redirected communications circuits. This is realized by providing provisioning information to the ring nodes which includes the identity of all communications circuits active in the ring and whether there is an alternate ring node to which any of the communications circuits may be redirected.
