Abstract: ONE CHUCK GRINDING APPARATUS FOR END MILLING  CUTTERS AND THE LIKE     ABSTRACT OF THE DISCLOSURE Apparatus for manually sharpening the bottom, radially divergent, flute ends or cutting edges of an end milling cutter (hereinafter referred to as an "end mill") which apparatus includes: a stationary, beveled disc-type or plain grinding wheel mounted for rotation about a horizontal axis (or y-axis), so as to present the face of the wheel to an operator, and a tool-holding fixture having a base member mounted on the worktable of a conventional tool grinder. The worktable of the grinder is capable of movement along three axes, namely a longitudinal axis (or x-axis), a horizontal axis (or y-axis) toward and away from the circular face of the disc, and a vertical axis (or z-axis), by manual manipulation of individual table-adjucting wheels. The fixture includes a workhead mounted on a carriage which inturn is translatably mounted for linear to and fro motion, on a base member withbearing means The workhead is mounted on the carriage for pivotable movement about a longitudinal axis (x-axis). An end mill holder comprising a bushing or collet is rotatably disposed in the workhead so that the end mill may be rotated about the end mill's longitudinal (vertical) axis. The end mill is held in a vertical plane, and index plate means are preferably provided for indexing each cutting tooth or edge of an end mill along the y-axis before it is sharpened. Once the end mill is locked into the holder, or "chucked", the end mill may be dished and gashed, and primary and secondary clearances of the flute ends may be provided, all without removingthe end mill, hence the "one chuck" designation.

Title: Purification of pertussis haemagglutinins
Inventor: IRONS LAURENCE I
IPC: C07K14/235
Filed: 1979-03-01
Granted: 1981-12-15
Abstract: ABSTRACT   The Leukocytosis Promoting Factor (LPF) of Bordetella haemagglutinin (HG) is separated from crude cell supernatant or partially purified protein by affinity chromatography on a column material consisting of an insoluble polymeric support to which is bound a sialoprotein (glycoprotein containing sialic acid) or other substance rich in sialic acid.  The sialoprotein was preferably a plasma sialoprotein such as haptoglobin or ceruloplasmin or a salivary mucin, and the polymeric support was preferably an agarose gel, though other conventional sup-ports could be used.  By this process, on treatment of an ammonium sulphate pre-cipitated extract, the haemagglutinating activity may be increased 300-600 fold over the extract and 10,000 times over the crude centrifuged cell supernatant. Alternatively a fraction substantially free from LPF-HG may be collected.  Pertus-sis LPF-HG is reported to have various useful clinical properties, in particular adjuvant effect on antigenicity and the abilities to induce leukocytosis and sensitivity to histamine.  By the process of the present invention LPF-HG may be produced cheaply and in large quantities or removed from other cell extracts.
