Title: Induction of the acrosome reaction to evaluate the fertilization capability of mammalian sperm
Inventor: TEZON JORGE G
IPC: C12N5/076
Filed: 1995-02-21
Abstract: Disclosed  is  a  method  of  evaluating  the in vitro or in vivo fertilization capability of a given sperm  sample.    The  method  involves the  steps  of capacitating a sample of mammalian sperm cells followed by incubating the capacitated sperm with a predetermined amount of a glycoside-macromolecule conjugate such as a neoglycoprotein or a glycodendrimer for a period of time and under conditions sufficient to induce an acrosome reaction in the sperm.  This step effectively mimics the physiological reaction that occurs in vivo between a sperm and an egg.  The extent of the conjugate-induced acrosome  reaction in the  sperm cells  relative  to  a positive control and a negative control, which account for the percent of sperm in the sample that acrosome react     non-physiologically     and     spontaneously, respectively,  is then calculated.   The  fertilization capability of the sperm is then evaluated as a function of the extent of this calculation.   Also disclosed are kits  which  contain  the  necessary  materials   for conducting the method in a clinical laboratory.

Title: Safety equipment for passenger conveying plants
Inventor: STAWNIAK ANDRZEJ
IPC: B66B29/06
Filed: 1996-04-23
Abstract: Safety equipment for passenger conveying plants, in particular for escalators and moving walkways with at least one comb plate which actuates a safety switch by way of trigger means in the case of a force action exceeding a settable amount in horizontal or in vertical direction. The comb plate is movable horizontally and vertically against the static force of a force F or against its components Fh and Fv. The static triggering force F is set by means of a biasable spring (5) and divided into the static triggering force components Fh and Fv by an adjustable angular position of the line of action of the spring (5). The ratio Fh:Fv is selectable by appropriate angular position of the line of action of the spring (5). The setting of the angular position is possible by simple manual resetting within a certain angular range without constructional action on the safety equipment.      Detent notches (12) and detent pins (13) assure a constant maintenance of the set angle.

Abstract: An annular nozzle  for an oxygen lance, e.g. an oxygen lance for blowing steel in a converter, gives an annular hot spot on the liquid steel in the converter .  When exiting the nozzle, the annular jet has disruptions that result in ambient atmosphere being sucked in  towards the centre of the annular jet.  Thus, a sub-pressure is prevented which would otherwise prevent the jet from diverging conically.  In one embodiment, the nozzle can be switched during a blowing operation between forming a tight jet and forming a diverging jet.

Title: Adhesive sealant composition
Inventor: BARROWS THOMAS H
IPC: A61L24/00
Filed: 1995-06-23
Abstract: This invention is related to an adhesive composition which may be used to bond or seal tissue in vivo. The adhesive composition is readily formed from a two-component mixture which includes a first part of a protein, preferably a serum albumin protein, in an aqueous buffer having a pH in the range of about 8.0-11.0 and a second part of a water-compatible or water-soluble bifunctional crosslinking agent. When the two parts of the mixture are combined, the mixture is initially a liquid which cures in vivo on the surface of tissue in less than about one minute to give a strong, flexible, pliant substantive composition which bonds to the tissue and is absorbed in about four to sixty days. The adhesive composition may be used either to bond tissue, to seal tissue or to prevent tissue adhesions caused by surgery.
