Title: Interferon assay
Inventor: RYBACEK LUDVIK
IPC: G01N33/68
Filed: 1987-10-14
Granted: 1991-09-10
Abstract: ABSTRACT OF THE DISCLOSURE    A  rapid  assay  for  quantifying  the  amounts  of interferon in liquid samples  is provided.   The assay employs  an  affinity  column,  containing  immobilized anti-interferon   antibodies,    in   series   with   a reversed-phase column.   The assay  is  able to measure interferon    concentrations    as    low    as    1-2 micrograms/milliliter in total assay times of less than one hour.   By suitably adjusting the elution gradient used   with   the   reversed-phase   column,   different interferon subtypes,  e.g.,  monomeric  and  oligomeric forms of .alpha.2-interferon, can be separately detected and quantified.   In certain preferred embodiments,  errors due to non-speciic binding are minimized by treating the affinity column with an albumin-contalning buffer prior to each assay.

Granted: 1992-04-28
Abstract: Abstract A gondola for the transport of animals to be slaugh-tered  preferably hogs, in an anaesthesia system A gondola for the transport of animals to be slaugh-tered, preferably hogs, in an anaesthesia system, said gondola (9) comprising two end gables including an outer and gable (10)  and an inner end gable (11). The inner end gable (11) is permanently fas-tened to a bottom (14) and a second side wall (15). The bottom (14) with the inner end gables (11) and the second side wall  (15)  are pivotably mounted around a fixed rotational shaft (16). The gondola comprises furthermore a first side wall (17) above pivotably mounted around a shaft  (23)  extending parallel to the shaft (16) between the two outer end gables (10). The upper parts of the inner end gables (11) adjacent the first side wall are pro-vided with a traverse shaft extending in the longi-tudinal direction of the gondola. The end of said shaft facing the first side wall (17) carries a pulley in engagement with a guide track (20) on the first side wall (17), while the opposite end of said shaft carries  a projecting pulley  (37) provided to engage with a cam-forming guide means (39) when the gondola passes an exit of the anaes-thesia system.  Under the influence of the guide means (39) the bottom (14) with the second side wall (15) and the inner end gable (11) is rotated around the rotational  shaft  (17),  while  the pulley in engagement with the guide track (20) rotates the first  side wall  (17)  in the  opposite direction around the rotational shaft (23) by moving in the guide track. As a result a gap is provided between the bottom (14) and the first side wall (17), said gap being automatically closed when the permanently fixed guide means (39) enables the rotating parts to return to their starting positions by means of the force of gravity. Thus the permanently fixed guide means (39) enables the gondola (9) to auto-matically deliver the unconscious animals.

Granted: 1992-04-07
Abstract: ABSTRACT OF THE DISCLOSURE      To secure roadways and wall surfaces of open cuts and tunnels, a rock anchor assembly is inserted into and secured within a borehole in a receiving material.  The rock anchor assembly is made up of an axially elongated tension member laterally enclosed in part by an axially elongated sheathing tube so that the tension member projects outwardly from the opposite ends of the sheathing tube.  In the insertion direc-tion, the leading end of the sheathing tube is secured in tension-resistant locked engagement with the tension member.          Initially, a hardenable adhesive material is injected into a borehole and then the assembled tension member and sheathing tube are inserted into the adhesive material so that the un-sheathed end of the tension member is anchored in the base of the borehole.  The trailing end of the sheathing tube has a flange which bears against a anchor plate in contact with the surface of the receiving material in which the borehole is formed.  An anchor nut is secured on the tension member and presses the trailing end of the sheathing tube against the anchor plate and the anchor plate against the receiving mate-rial.  Accordingly, the leading end of the tension member and the anchor plate can be used in common by both the tension member and the sheathing tube for anchoring purposes with the sheathing tube anchored at both of its ends.

Abstract: ABSTRACT     Hollow porous and non-porous microspheres are made from dispersed particle film forming compositions comprising dispersed particles, a binder, a film stabilizing agent, a dispersing agent and a continuous liquid phase.  The hollow porous microspheres have walls with voids which are interconnected to each other and to the inner and outer wall surfaces.  The microspheres can be made from dispersed particles of ceramic, glass, metal, metal glass, plastic, and mixtures thereof.  The microspheres can be used as filler materials and as supports and enclosures for catalysts.  The hollow microspheres are made by feeding the dispersed particle composition and a blowing gas to a coaxial blowing nozzle having an inner coaxial nozzle for the blowing gas and an outer coaxial nozzle for the dispersed particle composition.  The blowing gas is fed to the inner nozzle and the dispersed particle composition is fed to the outer nozzle to blow and form, in the region of the coaxial blowing nozzle orifice, hollow dispersed particle composition microspheres.  The hollow microspheres are removed from the region of the orifice and treated to bring the dispersed particles into point to point contact and to harden them to obtain hollow green microspheres, which are subjected to a sufficiently high temperature to remove the continuous liquid phase from the hollow green microspheres and to sinter the dispersed particles to obtain hollow porous microspheres.  The hollow porous microspheres can be treated with semipermeable membrane forming materials to make them non-porous and suitable for use in selective separation processes and in biotech processes.
