Patent FR-2467525-A1 (FR)
Inventor: DURAND ROGER
IPC: H04R11/12
Filed: 1980-09-01
Abstract: The stylus contrivance for a moving-magnet magnetic sound reproduction unit includes a tip-carrying tube (10), the end of which has been shaped to form a collar (11), and in which has been introduced a cylindrical permanent magnet (14). A suspension block (16), made from a flexible material such as polyvinyl chloride or an elastomer, is moulded over the said end of the tube (10). The edges of the suspension block (16), of square cross-section, make a specified angle alpha with the longitudinal axis of the tube (10), and the plane defined by the two upper and lower edges of the suspension block makes an angle beta equal to 90 DEG with the axial plane of the tube (10) containing the horizontal border of the flattened end of this tube, in such a way that the playing tip, which is mounted at the other end of the tube, is perfectly perpendicular to the plane of a record, after the assembly has been fitted to the playing arm framework.

Abstract: Monokines having the immunostimulant activity of Lymphocytes Activating Factor, or Interleukine I (LAF or IL -2), but free from pyrogenicity, are prepared from cell lines capable of liberating cytokines, such as lymphokines or monokines. The cell lines are incubated in primary cultures or in continued lines in an appropriate culture medium in the presence of homologues or derivatives of N-acetyl muramyl-L- alanyl-D-isoglutamine (MDP) that are themselves free from pyrogenicity. The product is recovered from the supernatant layer of the culture medium after the necessary incubation and may then be purified. The pref. cell lines are normal or tumoral granulocytes-macrophagic lines. Suitable homologues of MDP have been described in EP---6068.

Title: Vapour pressure control of iodide decomposition cell - for metal purificn., by direct vapour pressure measurement
IPC: C22B9/02
Filed: 1982-05-27
Abstract: The vapour pressure in an iodide decompsn. cell is controlled by direct measurement of the vapour pressure in the cell and use of this measurement to control the vapour pressure, e.g. by controlling the temp. of the cell lid or the amt. of iodine in the cell.
