Title: Prodn. of gamma globulin solns. from intravenous injection - by treating a normal globulin soln. with e.g. ethyl acetimidate hydrochloride
Inventor: STEPHAN WOLFGANG DR PHIL
IPC: C07K16/00
Filed: 1976-04-03
Abstract: Prepn. comprises treating a normal soln. of gamma-globulin with (per g of protein) (A) 0.055g ethyl acetimidate hydrochloride; (B) 0.022g diketene; (C) 0.05g ethyl formimidate hydrochloride or (D) 0.077g propane sultone. Treatment is at 5 degrees C for (A), (B) and (C) and at 37 degrees C for (D), and at pH 9, and after allowing to react for 2 hr. the pH is adjusted to 7-7.5 then the mixt. dialysed and sterile-filtered. The parent patent described the modification of gamma-globulin with other alkylating or acylating agents such as beta-propiolactone. The compsns. have specific complement-fixing activity so cause bacteriolysis in cases of bacterial infections. In cases (A) and (B) reaction is more rapid than with propiolactone so can be carried out under milder conditions; (D) introduces sulphonamide gps. into the protein which themselves protect against infection and in (C) the mol. wt. of the treating agent is so low that only a minimal alteration in the immunological properties of the globulin occurs so tolerance is improved on longer-term administration.

Title: Continuous hot strip rolling mill - using min. strip tension in finishing train so laminar water cooling of strip can be used
Inventor: KNUEHL HELMUT
IPC: B21B37/74
Filed: 1977-05-14
Abstract: Laminar water cooling of the rolled strip is carried out between roll stands in the finishing train of a continuous hot strip rolling mill, where minimum tension is exerted on the strip travelling through the six roll stands in the finishing train. Each of the six stands is driven by a d.c. motor using tension controllers to maintain a low tension of only 0.2-0.5kg/mm2 on the strip. The result is that the strip travels in a horizontal plane through a water bath so optimum cooling is achieved. There is no need to use loops of strip between the stands. Such looping entails the use of additional plant and measuring appts., and it is very difficult to achieve uniform cooling, whereas the invention uses laminar water flow which ensures uniform cooling.
