Title: Immunoglobulins isolation from serum or plasma - by selective adsorption on inorganic adsorbents
Inventor: MUELLER HANS
IPC: C07K16/30
Filed: 1974-01-30
Abstract: Process for recovering or enriching immunoglobulins IgG, IgA and IgM from serum or plasma involves the steps of (a) precipitating a crude immunoglobulin fraction from serum or defibrinated plasma with a short-chain prim. alcohol; (b) bringing the ppte. into aq. soln. and pptg. the euglobins by adjusting to low conductivity and weakly acidic pH; (c) removing proteolytic enzymes from the supernatant by adsorption on a mineral adsorbant; (d) in the supernatant from step (c), adsorbing the majority of the IgM (together with other protens) on poorly soluble phosphate and separating of the adsorbate; (e) desorbing an IgM fraction from the adsorbate of step (d) and enriching by pptn. with a short-chain prim. alcohol; (f) bringing the ppte. from step (e) into aq. soln. and treating with aluminium hydroxide (which is subsequently separated off) to remove impurities; (g) precipitating IgG and IgA from the supernatant of step (d) with a short-chain prim. alcohol; and (h) opt. separating the IgG and IgA by selectively adsorbing the IgA on aluminium hydroxide. The purified immunoglobulins are of use in the immunotherapy of bacterial and viral infections, as well as in diagnostic reagents. Igg, IgA and IgM are produced in high yield and purity. The immunoglobulins are obtd. free from Australia antigen, and can therefore be regarded as being free from hepatitis virus.

Title: Conductor rails for AC rail traction - with each rail enclosed in insulation and held together into single assembly
Inventor: HOLTMEIER GERHARD DIPL ING
IPC: B60M1/34
Filed: 1974-05-22
Abstract: Each conductor rail (1, 2, 3) is formed with a constant cross section and has a raised edge (6) which forms the pick-up strip for the contact shoe. Each rail is enclosed in a separate insulator (7) which is moulded around the pick-up strip to form a slot (10) to guide and enclose the contact shoe. The separate conductor rails are then assembled into a single unit by an outside cover (15) and are arranged so that the adjacent rails are staggered in height. This reduces the impedance between adjacent rails and forms a compact layout. When used for three-phase traction in cranes etc. the impedance between closely spaced rails can be more than the resistance of the rails.
Patent DE-2429393-A1 (DE)
Title: Mixing polyelectrolyte flocculating soln without agglomeration - by drying followed by wetting with fine spray
Inventor: HOFFMANN HANS E
IPC: B01F5/20
Filed: 1974-06-19
Abstract: An appts. for the dissolving prepn. of flocculating agent, esp. polyelectrolytes, comprises a storage vessel for the dry powder or granulate, discharging through a controlled outlet into a dispersion tank mounted underneath, in which the granulate is dissolved in the water. The discharge from the granulate store is effected by a metering screw heated at its discharge end, so that the granulate is thoroughly dried; the granulate then falls through an open-topped, open-bottomed dispersion chamber, in which a system of water spray nozzles produce a turbulent zone of high-speed mixed water and air; the dried particles are thus thoroughly wetted while still dispersed, so that they do not form clumps as they commence to swell with absorption of moisture. The material then falls into a dissolving and collecting chamber. This chamber pref. consists of a number of compartments, each feeding the next through an overflow pipe and each contg. an agitator, the last compartment discharging through a metering pump. The dispersion chamber is pref. upwardly and downwardly tapering as a double conical frustrum. The water jets are pref. flat conical jets directed slightly downwards. Heating at the discharge end of the screw is by electrical resistance heaters. In the storage vessel, there may be an additional, wide-pitch screw around the discharge screw at its upper end, to loosen the material. Therefore plates may be mounted above the dispersion chamber, to prevent upward escape of disty mist. The appts. is useful for preparing flocculating agent for all types of water prepn. and treatment. The appts. enables the material to be thoroughly dried and then uniformly wetted by a fine spray before the granules can come together. This prevents clumping.
