Patent CA-2215738-A1 (CA)
Title: Rotary coin mechanism and token therefor
Inventor: SCHWARZLI JOSEF W
IPC: G07F1/06
Filed: 1997-09-17
Abstract: The invention provides a rotary coin mechanism in which the mechanism is provided with a boss which projects into the rotational path of the token. The boss allows rotation of the token carrier only if a token seated in the token receptacle is provided with a recess or groove complimentary to the boss and configured to approximate the rotational path of the token. In the preferred embodiment the groove has a first portion which is in line with the boss and a second portion which is offset from the first portion and connected thereto by a cam surface. As the token cycles past the boss, the boss passes from the first portion into the second portion of the groove and lifts the token within the token receptacle at the perimeter measuring point, so that only if the second portion of the groove is precisely positioned in the face of the token will the perimeter measuring device allow the token to pass. In a preferred embodiment the mechanism is also provided with a guide in the token receptacle comprising a pair of ribs compatible with one or more complimentary recesses or grooves in the token, to allow for insertion of the token. The preferred token thus has grooves in two directions: a first direction which is the direction of insertion of the token, and a second direction which is relatively orthogonal to the first and approximates the rotational path of the token as it is conveyed to the dispensing point by the token carrier. Also, in the preferred embodiment the grooves on opposite sides of the token are each formed deeper than one-half of the thickness of the token, so the points where these grooves intersect result in open spaces.

Inventor: PAUL HANNS-INGOLF
IPC: C07K1/18
Filed: 1998-05-29
Abstract: An improved process for the purification of antibodies from human plasma or other sources is disclosed. The process involves suspension of the antibodies at pH 3.8 to 4 5 followed by addition of caprylic acid and a pH shift to pH 5.0 to 5.2. A precipitate of contaminating proteins, lipids and caprylate forms and is removed, while the majority of the antibodies remain in solution. Sodium caprylate is again added to a final concentration of not less than about 15 mM. This solution is incubated for 1 hour at 25°C to effect viral inactivation. A precipitate (mainly caprylate) is removed and the clear solution is diluted with purified water to reduce ionic strength. Anion exchange chromatography using two different resins is utilized to obtain an exceptionally pure IgG with subclass distribution similar to the starting distribution. The method maximizes yield and produces a gamma globulin with greater than 99% purity.
