Title: Manufacture of specific vaccines
IPC: A61K41/00
Filed: 1920-08-20
Abstract: 150,328. Elektro-Osmose Akt.-Ges., (Graf Schwerin Ges.). Aug. 23, 1919, [Convention date]. Vaccines and immunizing serums.-Specific vaccines for the active immunization of men or animals are prepared by causing a continuous electric current to act on emulsions of dead bacteria so that the cell contents are liberated by osmotic action. The living bacteria are killed by the action of an electric current, as described in Specification 150,318, or otherwise and are then subjected to the action of a continuous current of medium strength and low voltage for several hours. In an example, a current of 12 amperes at 15 to 25 volts is employed in apparatus having an effective electrode surface of 400 sq. cms. The process causes the cell contents to issue into the surrounding medium, and in most cases causes granular disintegration of the cell walls. For immunization, the clear extract, or the cell walls or residues, or a mixture thereof, may be employed. The clear extract may be concentrated by evaporation under reduced pressure. Specified vaccines are those obtained from the bacilli of swine erysipelas, chicken cholera, and tuberculosis. Osmotic treatment of bacteria by simple immersion in water or in very dilute or concentrated sult solutions is also referred to.

Filed: 1951-10-18
Abstract: 714,081. Gauging-apparatus. SHEFFIELD CORPORATION. Oct. 18, 1951 (Nov. 4, 1950], No. 24320/51. Class 106 (2) Apparatus for gauging or checking the contour of a workpiece comprises a carrier for gauge heads each having gauging means including a movable work contactor and a fluid leakage orifice controlled thereby, and indicating means responsive to each of the gauging means. As shown, the apparatus comprises a base 10, Figs. 2 and 4, on which is mounted a holder 11 for a workpiece such as a turbine blade 12, and carriers 13, 14 which may be moved by operating handles 22, along guides 19, 20 until arrested by adjustable stops in a predetermined gauging position. Fig. 4. On each carrier are brackets such as 30 supported by bolts 33 vertically adjustable along slots 34, and each bracket carries gauge heads 15 held by clamps 38 and adjustably mounted by bolts 39 engaging threaded holes 40. Each gauge head is similar to that described in Specification 705,708 and comprises a spring- urged work contactor 37, Fig. 8, whose pointed end controls an air leakage orifice 42 at the end of tube 46. Air pressure is supplied through regulators 50 and 51, Fig. 3, to tapered tubes 17, containing indicating floats, the air flow continuing to the tubes 46 via.passages 52 and flexible conduits 48. Thus the height of the float in a tube 17 depends on the size of the corresponding orifice 42, Fig. 8, and therefore on the position to which the contactor 37 is moved by the workpiece when engaged therewith. The base of the workpiece may be clamped in a member 64, Fig. 3, by depressing a valve-controlling foot pedal 59 thereby supplying air pressure from regulator 56 to cylinder 60 and operating plunger 61. To set up the apparatus the bifurcated ends of tolerance limit feelers 67, 68, Fig. 10, are engaged in turn with a gauge head contactor 37, Fig. 8, between surfaces 69, 70, and the corresponding float brought to the level of respective limit lines 68<SP>1</SP>, Fig. 2, on a vertically adjustable screen 67' by adjustment :of valves 53, 54; Fig. 3. The gauge head is then placed on a carrier (in gauging position) in contact with a master blade (which need not be of perfect form provided its deviations from normal are known and within the tolerance limits), and is adjusted until the float indicates the correct reading for the point at which the master blade is engaged, this process being repeated for all the other gauge heads.
